# DeerFlow Smoke Test Skill
|
||||
|
||||
This skill guides the Agent through DeerFlow's full end-to-end smoke test workflow, including code updates, deployment (supporting both Docker and local installation modes), service availability verification, and health checks.
|
||||
|
||||
## Deployment Mode Selection
|
||||
|
||||
This skill supports two deployment modes:
|
||||
- **Local installation mode** (recommended, especially when network issues occur) - Run all services directly on the local machine
|
||||
- **Docker mode** - Run all services inside Docker containers
|
||||
|
||||
**Selection strategy**:
|
||||
- If the user explicitly asks for Docker mode, use Docker
|
||||
- If network issues occur (such as slow image pulls), automatically switch to local mode
|
||||
- Default to local mode whenever possible
|
||||
|
||||

|
||||
## Standard Operating Procedure (SOP)
|
||||
|
||||
### Phase 1: Code Update Check
|
||||
|
||||
1. **Confirm current directory** - Verify that the current working directory is the DeerFlow project root
|
||||
2. **Check Git status** - See whether there are uncommitted changes
|
||||
3. **Pull the latest code** - Use `git pull origin main` to get the latest updates
|
||||
4. **Confirm code update** - Verify that the latest code was pulled successfully
|
||||
|
||||
### Phase 2: Deployment Mode Selection and Environment Check
|
||||
|
||||
**Choose deployment mode**:
|
||||
- Ask for user preference, or choose automatically based on network conditions
|
||||
- Default to local installation mode
|
||||
|
||||
**Local mode environment check**:
|
||||
1. **Check Node.js version** - Requires 22+
|
||||
2. **Check pnpm** - Package manager
|
||||
3. **Check uv** - Python package manager
|
||||
4. **Check nginx** - Reverse proxy
|
||||
5. **Check required ports** - Confirm that ports 2026, 3000, 8001, and 2024 are not occupied
|
||||
|
||||
**Docker mode environment check** (if Docker is selected):
|
||||
1. **Check whether Docker is installed** - Run `docker --version`
|
||||
2. **Check Docker daemon status** - Run `docker info`
|
||||
3. **Check Docker Compose availability** - Run `docker compose version`
|
||||
4. **Check required ports** - Confirm that port 2026 is not occupied
|
||||
|
||||
### Phase 3: Configuration Preparation
|
||||
|
||||
1. **Check whether config.yaml exists**
|
||||
- If it does not exist, run `make config` to generate it
|
||||
- If it already exists, check whether it needs an upgrade with `make config-upgrade`
|
||||
2. **Check the .env file**
|
||||
- Verify that required environment variables are configured
|
||||
- Especially model API keys such as `OPENAI_API_KEY`
|
||||
|
||||
### Phase 4: Deployment Execution
|
||||
|
||||
**Local mode deployment**:
|
||||
1. **Check dependencies** - Run `make check`
|
||||
2. **Install dependencies** - Run `make install`
|
||||
3. **(Optional) Pre-pull the sandbox image** - If needed, run `make setup-sandbox`
|
||||
4. **Start services** - Run `make dev-daemon` (background mode, recommended) or `make dev` (foreground mode)
|
||||
5. **Wait for startup** - Give all services enough time to start completely (90-120 seconds recommended)
|
||||
|
||||
**Docker mode deployment** (if Docker is selected):
|
||||
1. **Initialize Docker environment** - Run `make docker-init`
|
||||
2. **Start Docker services** - Run `make docker-start`
|
||||
3. **Wait for startup** - Give all containers enough time to start completely (60 seconds recommended)
|
||||
|
||||
### Phase 5: Service Health Check
|
||||
|
||||
**Local mode health check**:
|
||||
1. **Check process status** - Confirm that LangGraph, Gateway, Frontend, and Nginx processes are all running
|
||||
2. **Check frontend service** - Visit `http://localhost:2026` and verify that the page loads
|
||||
3. **Check API Gateway** - Verify the `http://localhost:2026/health` endpoint
|
||||
4. **Check LangGraph service** - Verify the availability of relevant endpoints
|
||||
5. **Frontend route smoke check** - Run `bash .agent/skills/smoke-test/scripts/frontend_check.sh` to verify key routes under `/workspace`
|
||||
|
||||
**Docker mode health check** (when using Docker):
|
||||
1. **Check container status** - Run `docker ps` and confirm that all containers are running
|
||||
2. **Check frontend service** - Visit `http://localhost:2026` and verify that the page loads
|
||||
3. **Check API Gateway** - Verify the `http://localhost:2026/health` endpoint
|
||||
4. **Check LangGraph service** - Verify the availability of relevant endpoints
|
||||
5. **Frontend route smoke check** - Run `bash .agent/skills/smoke-test/scripts/frontend_check.sh` to verify key routes under `/workspace`
|
||||
|
||||
### Optional Functional Verification
|
||||
|
||||
1. **List available models** - Verify that model configuration loads correctly
|
||||
2. **List available skills** - Verify that the skill directory is mounted correctly
|
||||
3. **Simple chat test** - Send a simple message to verify the end-to-end flow
|
||||
|
||||
### Phase 6: Generate Test Report
|
||||
|
||||
1. **Collect all test results** - Summarize execution status for each phase
|
||||
2. **Record encountered issues** - If anything fails, record the error details
|
||||
3. **Generate the final report** - Use the template that matches the selected deployment mode to create the complete test report, including overall conclusion, detailed key test cases, and explicit frontend page / route results
|
||||
4. **Provide follow-up recommendations** - Offer suggestions based on the test results
|
||||
|
||||
## Execution Rules
|
||||
|
||||
- **Follow the sequence** - Execute strictly in the order described above
|
||||
- **Idempotency** - Every step should be safe to repeat
|
||||
- **Error handling** - If a step fails, stop and report the issue, then provide troubleshooting suggestions
|
||||
- **Detailed logging** - Record the execution result and status of each step
|
||||
- **User confirmation** - Ask for confirmation before potentially risky operations such as overwriting config
|
||||
- **Mode preference** - Prefer local mode to avoid network-related issues
|
||||
- **Template requirement** - The final report must use the matching template under `templates/`; do not output a free-form summary instead of the template-based report
|
||||
- **Report clarity** - The execution summary must include the overall pass/fail conclusion plus per-case result explanations, and frontend smoke check results must be listed explicitly in the report
|
||||
- **Optional phase handling** - If functional verification is not executed, do not present it as a separate skipped phase in the final report
|
||||
|
||||
## Known Acceptable Warnings
|
||||
|
||||
The following warnings can appear during smoke testing and do not block a successful result:
|
||||
- Feishu/Lark SSL errors in Gateway logs (certificate verification failure) can be ignored if that channel is not enabled
|
||||
- Warnings in LangGraph logs about missing methods in the custom checkpointer, such as `adelete_for_runs` or `aprune`, do not affect the core functionality
|
||||
|
||||
## Key Tools
|
||||
|
||||
Use the following tools during execution:
|
||||
|
||||
1. **bash** - Run shell commands
|
||||
2. **present_file** - Show generated reports and important files
|
||||
3. **task_tool** - Organize complex steps with subtasks when needed
|
||||

- If there are uncommitted changes, recommend that the user commit or stash them first to avoid conflicts while pulling
|
||||
- If the user confirms that they want to continue, this step can be skipped
|
||||
|
||||
---
|
||||
|
||||
### 1.3 Pull the Latest Code

### Issue: API Gateway Health Check Fails
|
||||
|
||||
**Symptoms**:
|
||||
Accessing `/health` returns an error or times out.
|
||||
|
||||
**Solutions** (local mode):
|
||||
1. Check gateway logs:
|
||||
```bash
|
||||
tail -f logs/gateway.log
|
||||
```
|
||||
|
||||
2. Confirm that config.yaml exists and has valid formatting
|
||||
3. Check whether Python dependencies are complete
|
||||
4. Confirm that the LangGraph service is running normally
|
||||
|
||||
**Solutions** (Docker mode):
|
||||
1. Check gateway container logs:
|
||||
```bash
|
||||
make docker-logs-gateway
|
||||
```
|
||||
|
||||
2. Confirm that config.yaml is mounted correctly
|
||||
3. Check whether Python dependencies are complete
|
||||
4. Confirm that the LangGraph service is running normally

# Copilot Onboarding Instructions for DeerFlow
|
||||
|
||||
Use this file as the default operating guide for this repository. Follow it first, and only search the codebase when this file is incomplete or incorrect.
|
||||
|
||||
## 1) Repository Summary
|
||||
|
||||
DeerFlow is a full-stack "super agent harness".
|
||||
|
||||
- Backend: Python 3.12, LangGraph + FastAPI gateway, sandbox/tool system, memory, MCP integration.
|
||||
- Frontend: Next.js 16 + React 19 + TypeScript + pnpm.
|
||||
- Local dev entrypoint: root `Makefile` starts backend + frontend + nginx on `http://localhost:2026`.
|
||||
- Docker dev entrypoint: `make docker-*` (mode-aware provisioner startup from `config.yaml`).
|
||||
|
||||
Current repo footprint is medium-large (backend service, frontend app, docker stack, skills library, docs).
|
||||
|
||||
## 2) Runtime and Toolchain Requirements
|
||||
|
||||
Validated in this repo on macOS:
|
||||
|
||||
- Node.js `>=22` (validated with Node `23.11.0`)
|
||||
- pnpm (repo expects lockfile generated by pnpm 10; validated with pnpm `10.26.2` and `10.15.0`)
|
||||
- Python `>=3.12` (CI uses `3.12`)
|
||||
- `uv` (validated with `0.7.20`)
|
||||
- `nginx` (required for `make dev` unified local endpoint)
|
||||
|
||||
Always run from repo root unless a command explicitly says otherwise.
|
||||
|
||||
## 3) Build/Test/Lint/Run - Verified Command Sequences
|
||||
|
||||
These were executed and validated in this repository.
|
||||
|
||||
### A. Bootstrap and install
|
||||
|
||||
1. Check prerequisites:
|
||||
|
||||
```bash
|
||||
make check
|
||||
```
|
||||
|
||||
Observed: passes when required tools are installed.
|
||||
|
||||
2. Install dependencies (recommended order: backend then frontend, as implemented by `make install`):
|
||||
|
||||
```bash
|
||||
make install
|
||||
```
|
||||
|
||||
### B. Backend CI-equivalent validation
|
||||
|
||||
Run from `backend/`:
|
||||
|
||||
```bash
|
||||
make lint
|
||||
make test
|
||||
```
|
||||
|
||||
Validated results:
|
||||
|
||||
- `make lint`: pass (`ruff check .`)
|
||||
- `make test`: pass (`277 passed, 15 warnings in ~76.6s`)
|
||||
|
||||
CI parity:
|
||||
|
||||
- `.github/workflows/backend-unit-tests.yml` runs on pull requests.
|
||||
- CI executes `uv sync --group dev`, then `make lint`, then `make test` in `backend/`.
|
||||
|
||||
### C. Frontend validation
|
||||
|
||||
Run from `frontend/`.
|
||||
|
||||
Recommended reliable sequence:
|
||||
|
||||
```bash
|
||||
pnpm lint
|
||||
pnpm typecheck
|
||||
BETTER_AUTH_SECRET=local-dev-secret pnpm build
|
||||
```
|
||||
|
||||
Observed failure modes and workarounds:
|
||||
|
||||
- `pnpm build` fails without `BETTER_AUTH_SECRET` in production-mode env validation.
|
||||
- Workaround: set `BETTER_AUTH_SECRET` (best) or set `SKIP_ENV_VALIDATION=1`.
|
||||
- Even with `SKIP_ENV_VALIDATION=1`, Better Auth can still warn/error in logs about default secret; prefer setting a real non-default secret.
|
||||
- `pnpm check` currently fails (`next lint` invocation is incompatible here and resolves to an invalid directory). Do not rely on `pnpm check`; run `pnpm lint` and `pnpm typecheck` explicitly.
|
||||
|
||||
### D. Run locally (all services)
|
||||
|
||||
From root:
|
||||
|
||||
```bash
|
||||
make dev
|
||||
```
|
||||
|
||||
Behavior:
|
||||
|
||||
- Stops existing local services first.
|
||||
- Starts LangGraph (`2024`), Gateway (`8001`), Frontend (`3000`), nginx (`2026`).
|
||||
- Unified app endpoint: `http://localhost:2026`.
|
||||
- Logs: `logs/langgraph.log`, `logs/gateway.log`, `logs/frontend.log`, `logs/nginx.log`.
|
||||
|
||||
Stop services:
|
||||
|
||||
```bash
|
||||
make stop
|
||||
```
|
||||
|
||||
If tool sessions/timeouts interrupt `make dev`, run `make stop` again to ensure cleanup.
|
||||
|
||||
### E. Config bootstrap
|
||||
|
||||
From root:
|
||||
|
||||
```bash
|
||||
make config
|
||||
```
|
||||
|
||||
Important behavior:
|
||||
|
||||
- This intentionally aborts if `config.yaml` (or `config.yml`/`configure.yml`) already exists.
|
||||
- Use `make config` only for first-time setup in a clean clone.
|
||||
|
||||
## 4) Command Order That Minimizes Failures
|
||||
|
||||
Use this exact order for local code changes:
|
||||
|
||||
1. `make check`
|
||||
2. `make install` (if frontend fails with proxy errors, rerun frontend install with proxy vars unset)
|
||||
3. Backend checks: `cd backend && make lint && make test`
|
||||
4. Frontend checks: `cd frontend && pnpm lint && pnpm typecheck`
|
||||
5. Frontend build (if UI changes or release-sensitive changes): `BETTER_AUTH_SECRET=... pnpm build`
|
||||
|
||||
Always run backend lint/tests before opening PRs because that is what CI enforces.
|
||||
|
||||
## 5) Project Layout and Architecture (High-Value Paths)
|
||||
|
||||
Root-level orchestration and config:
|
||||
|
||||
- `Makefile` - main local/dev/docker command entrypoints
|
||||
- `config.example.yaml` - primary app config template
|
||||
- `config.yaml` - local active config (gitignored)
|
||||
- `docker/docker-compose-dev.yaml` - Docker dev topology
|
||||
- `.github/workflows/backend-unit-tests.yml` - PR validation workflow
|
||||
|
||||
Backend core:
|
||||
|
||||
- `backend/packages/harness/deerflow/agents/` - lead agent, middleware chain, memory
|
||||
- `backend/app/gateway/` - FastAPI gateway API
|
||||
- `backend/packages/harness/deerflow/sandbox/` - sandbox provider + tool wrappers
|
||||
- `backend/packages/harness/deerflow/subagents/` - subagent registry/execution
|
||||
- `backend/packages/harness/deerflow/mcp/` - MCP integration
|
||||
- `backend/langgraph.json` - graph entrypoint (`deerflow.agents:make_lead_agent`)
|
||||
- `backend/pyproject.toml` - Python deps and `requires-python`
|
||||
- `backend/ruff.toml` - lint/format policy
|
||||
- `backend/tests/` - backend unit and integration-like tests
|
||||
|
||||
Frontend core:
|
||||
|
||||
- `frontend/src/app/` - Next.js routes/pages
|
||||
- `frontend/src/components/` - UI components
|
||||
- `frontend/src/core/` - app logic (threads, tools, API, models)
|
||||
- `frontend/src/env.js` - env schema/validation (critical for build behavior)
|
||||
- `frontend/package.json` - scripts/deps
|
||||
- `frontend/eslint.config.js` - lint rules
|
||||
- `frontend/tsconfig.json` - TS config
|
||||
|
||||
Skills and assets:
|
||||
|
||||
- `skills/public/` - built-in skill packs loaded by agent runtime
|
||||
|
||||
## 6) Pre-Checkin / Validation Expectations
|
||||
|
||||
Before submitting changes, run at minimum:
|
||||
|
||||
- Backend: `cd backend && make lint && make test`
|
||||
- Frontend (if touched): `cd frontend && pnpm lint && pnpm typecheck`
|
||||
- Frontend build when changing env/auth/routing/build-sensitive files: `BETTER_AUTH_SECRET=... pnpm build`
|
||||
|
||||
If touching orchestration/config (`Makefile`, `docker/*`, `config*.yaml`), also run `make dev` and verify the four services start.
|
||||
|
||||
## 7) Non-Obvious Dependencies and Gotchas
|
||||
|
||||
- Proxy env vars can silently break frontend network operations (`pnpm install`/registry access).
|
||||
- `BETTER_AUTH_SECRET` is effectively required for reliable frontend production build validation.
|
||||
- Next.js may warn about multiple lockfiles and workspace root inference; this is currently a warning, not a build blocker.
|
||||
- `make config` is non-idempotent by design when config already exists.
|
||||
- `make dev` includes process cleanup and can emit shutdown logs/noise if interrupted; this is expected.
|
||||
|
||||
## 8) Root Inventory (quick reference)
|
||||
|
||||
Important root entries:
|
||||
|
||||
- `.github/`
|
||||
- `backend/`
|
||||
- `frontend/`
|
||||
- `docker/`
|
||||
- `skills/`
|
||||
- `scripts/`
|
||||
- `docs/`
|
||||
- `README.md`
|
||||
- `CONTRIBUTING.md`
|
||||
- `Makefile`
|
||||
- `config.example.yaml`
|
||||
- `extensions_config.example.json`
|
||||
|
||||
## 9) Instruction Priority
|
||||
|
||||
Trust this onboarding guide first.
|
||||
|
||||
Only do broad repo searches (`grep/find/code search`) when:
|
||||
|
||||
- you need file-level implementation details not listed here,
|
||||
- a command here fails and you need updated replacement behavior,
|
||||
- or CI/workflow definitions have changed since this file was written.

# Contributor Covenant Code of Conduct
|
||||
|
||||
## Our Pledge
|
||||
|
||||
We as members, contributors, and leaders pledge to make participation in our
|
||||
community a harassment-free experience for everyone, regardless of age, body
|
||||
size, visible or invisible disability, ethnicity, sex characteristics, gender
|
||||
identity and expression, level of experience, education, socio-economic status,
|
||||
nationality, personal appearance, race, religion, or sexual identity
|
||||
and orientation.
|
||||
|
||||
We pledge to act and interact in ways that contribute to an open, welcoming,
|
||||
diverse, inclusive, and healthy community.
|
||||
|
||||
## Our Standards
|
||||
|
||||
Examples of behavior that contributes to a positive environment for our
|
||||
community include:
|
||||
|
||||
* Demonstrating empathy and kindness toward other people
|
||||
* Being respectful of differing opinions, viewpoints, and experiences
|
||||
* Giving and gracefully accepting constructive feedback
|
||||
* Accepting responsibility and apologizing to those affected by our mistakes,
|
||||
and learning from the experience
|
||||
* Focusing on what is best not just for us as individuals, but for the
|
||||
overall community
|
||||
|
||||
Examples of unacceptable behavior include:
|
||||
|
||||
* The use of sexualized language or imagery, and sexual attention or
|
||||
advances of any kind
|
||||
* Trolling, insulting or derogatory comments, and personal or political attacks
|
||||
* Public or private harassment
|
||||
* Publishing others' private information, such as a physical or email
|
||||
address, without their explicit permission
|
||||
* Other conduct which could reasonably be considered inappropriate in a
|
||||
professional setting
|
||||
|
||||
## Enforcement Responsibilities
|
||||
|
||||
Community leaders are responsible for clarifying and enforcing our standards of
|
||||
acceptable behavior and will take appropriate and fair corrective action in
|
||||
response to any behavior that they deem inappropriate, threatening, offensive,
|
||||
or harmful.
|
||||
|
||||
Community leaders have the right and responsibility to remove, edit, or reject
|
||||
comments, commits, code, wiki edits, issues, and other contributions that are
|
||||
not aligned to this Code of Conduct, and will communicate reasons for moderation
|
||||
decisions when appropriate.
|
||||
|
||||
## Scope
|
||||
|
||||
This Code of Conduct applies within all community spaces, and also applies when
|
||||
an individual is officially representing the community in public spaces.
|
||||
Examples of representing our community include using an official e-mail address,
|
||||
posting via an official social media account, or acting as an appointed
|
||||
representative at an online or offline event.
|
||||
|
||||
## Enforcement
|
||||
|
||||
Instances of abusive, harassing, or otherwise unacceptable behavior may be
|
||||
reported to the community leaders responsible for enforcement at
|
||||
willem.jiang@gmail.com.
|
||||
All complaints will be reviewed and investigated promptly and fairly.
|
||||
|
||||
All community leaders are obligated to respect the privacy and security of the
|
||||
reporter of any incident.
|
||||
|
||||
## Enforcement Guidelines
|
||||
|
||||
Community leaders will follow these Community Impact Guidelines in determining
|
||||
the consequences for any action they deem in violation of this Code of Conduct:
|
||||
|
||||
### 1. Correction
|
||||
|
||||
**Community Impact**: Use of inappropriate language or other behavior deemed
|
||||
unprofessional or unwelcome in the community.
|
||||
|
||||
**Consequence**: A private, written warning from community leaders, providing
|
||||
clarity around the nature of the violation and an explanation of why the
|
||||
behavior was inappropriate. A public apology may be requested.
|
||||
|
||||
### 2. Warning
|
||||
|
||||
**Community Impact**: A violation through a single incident or series
|
||||
of actions.
|
||||
|
||||
**Consequence**: A warning with consequences for continued behavior. No
|
||||
interaction with the people involved, including unsolicited interaction with

If Docker builds are slow in your network, you can override the default package registries before running `make docker-init` or `make docker-start`:
|
||||
|
||||
```bash
|
||||
export UV_INDEX_URL=https://pypi.org/simple
|
||||
export NPM_REGISTRY=https://registry.npmjs.org
|

```

||||
#### Recommended host resources
|
||||
|
||||
Use these as practical starting points for development and review environments:
|
||||
|
||||
| Scenario | Starting point | Recommended | Notes |
|
||||
|---------|-----------|------------|-------|
|
||||
| `make dev` on one machine | 4 vCPU, 8 GB RAM | 8 vCPU, 16 GB RAM | Best when DeerFlow uses hosted model APIs. |
|
||||
| `make docker-start` review environment | 4 vCPU, 8 GB RAM | 8 vCPU, 16 GB RAM | Docker image builds and sandbox containers need extra headroom. |
|
||||
| Shared Linux test server | 8 vCPU, 16 GB RAM | 16 vCPU, 32 GB RAM | Prefer this for heavier multi-agent runs or multiple reviewers. |
|
||||
|
||||
`2 vCPU / 4 GB` environments often fail to start reliably or become unresponsive under normal DeerFlow workloads.
|
||||
|
||||
#### Linux: Docker daemon permission denied
|
||||
|
||||
If `make docker-init`, `make docker-start`, or `make docker-stop` fails on Linux with an error like below, your current user likely does not have permission to access the Docker daemon socket:
|
||||
|
||||
```text
|
||||
unable to get image 'deer-flow-dev-langgraph': permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock
|
||||
```
|
||||
|
||||
Recommended fix: add your current user to the `docker` group so Docker commands work without `sudo`.
|
||||
|
||||
1. Confirm the `docker` group exists:
|
||||
```bash
|
||||
getent group docker
|
||||
```
|
||||
2. Add your current user to the `docker` group:
|
||||
```bash
|
||||
sudo usermod -aG docker $USER
|
||||
```
|
||||
3. Apply the new group membership. The most reliable option is to log out completely and then log back in. If you want to refresh the current shell session instead, run:
|
||||
```bash
|
||||
newgrp docker
|
||||
```
|
||||
4. Verify Docker access:
|
||||
```bash
|
||||
docker ps
|
||||
```
|
||||
5. Retry the DeerFlow command:
|
||||
```bash
|
||||
make docker-stop
|
||||
make docker-start
|
||||
```
|
||||
|
||||
If `docker ps` still reports a permission error after `usermod`, fully log out and log back in before retrying.

# DeerFlow Install
|
||||
|
||||
This file is for coding agents. If the DeerFlow repository is not already cloned and open, clone `https://github.com/bytedance/deer-flow.git` first, then continue from the repository root.
|
||||
|
||||
## Goal
|
||||
|
||||
Bootstrap a DeerFlow local development workspace on the user's machine with the least risky path available.
|
||||
|
||||
Default preference:
|
||||
|
||||
1. Docker development environment
|
||||
2. Local development environment
|
||||
|
||||
Do not assume API keys or model credentials exist. Set up everything that can be prepared safely, then stop with a concise summary of what the user still needs to provide.
|
||||
|
||||
## Operating Rules
|
||||
|
||||
- Be idempotent. Re-running this document should not damage an existing setup.
|
||||
- Prefer existing repo commands over ad hoc shell commands.
|
||||
- Do not use `sudo` or install system packages without explicit user approval.
|
||||
- Do not overwrite existing user config values unless the user asks.
|
||||
- If a step fails, stop, explain the blocker, and provide the smallest next action.
|
||||
- If multiple setup paths are possible, prefer Docker when Docker is already available.
|
||||
|
||||
## Success Criteria
|
||||
|
||||
Consider the setup successful when all of the following are true:
|
||||
|
||||
- The DeerFlow repository is cloned and the current working directory is the repo root.
|
||||
- `config.yaml` exists.
|
||||
- For Docker setup, `make docker-init` completed successfully and Docker prerequisites are prepared, but services are not assumed to be running yet.
|
||||
- For local setup, `make check` passed or reported no missing prerequisites, and `make install` completed successfully.
|
||||
- The user receives the exact next command to launch DeerFlow.
|
||||
- The user also receives any missing model configuration or referenced environment variable names from `config.yaml`, without inspecting secret-bearing files for actual values.
|
||||
|
||||
## Steps
|
||||
|
||||
- If the current directory is not the DeerFlow repository root, clone `https://github.com/bytedance/deer-flow.git` if needed, then change into the repository root.
|
||||
- Confirm the current directory is the DeerFlow repository root by checking that `Makefile`, `backend/`, `frontend/`, and `config.example.yaml` exist.
|
||||
- Detect whether `config.yaml` already exists.
|
||||
- If `config.yaml` does not exist, run `make config`.
|
||||
- Detect whether Docker is available and the daemon is reachable with `docker info`.
|
||||
- If Docker is available:
|
||||
- Run `make docker-init`.
|
||||
- Treat this as Docker prerequisite preparation only. Do not claim that app services, compose validation, or image builds have already succeeded.
|
||||
- Do not start long-running services unless the user explicitly asks or this setup request clearly includes launch verification.
|
||||
- Tell the user the recommended next command is `make docker-start`.
|
||||
- If Docker is not available:
|
||||
- Run `make check`.
|
||||
- If `make check` reports missing system dependencies such as `node`, `pnpm`, `uv`, or `nginx`, stop and report the missing tools instead of attempting privileged installs.
|
||||
- If prerequisites are satisfied, run `make install`.
|
||||
- Tell the user the recommended next command is `make dev`.
|
||||
- Inspect `config.yaml` only for missing model entries or referenced environment variable placeholders. Do not read `.env`, `frontend/.env`, or other secret-bearing files.
|
||||
- If no model is configured, tell the user they must add at least one entry under `models` in `config.yaml`.
|
||||
- If `config.yaml` references variables such as `$OPENAI_API_KEY`, tell the user which variable names still need real values, but do not verify them by opening secret-bearing files.
|
||||
- If the repository already appears configured, avoid repeating expensive work unless it is necessary to verify the environment.
|
||||
|
||||
## Verification
|
||||
|
||||
Use the lightest verification that matches the chosen setup path.
|
||||
|
||||
For Docker setup:
|
||||
|
||||
- Confirm `make docker-init` completed successfully.
|
||||
- Confirm `config.yaml` exists.
|
||||
- State explicitly that Docker services were not started and `make docker-start` is still the first real launch step.
|
||||
- Do not leave background services running unless the user asked for that.
|
||||
|
||||
For local setup:
|
||||
|
||||
- Confirm `make install` completed successfully.
|
||||
- Confirm `config.yaml` exists.
|
||||
- Do not leave background services running unless the user asked for that.
|
||||
|
||||
## Final Response Format
|
||||
|
||||
Return a short status report with:
|
||||
|
||||
1. Setup path used: Docker or local
|
||||
2. Setup level reached: Docker prerequisites prepared or local dependencies installed
|
||||
3. Files created or detected: for example `config.yaml`
|
||||
4. Remaining user action: model config, env var values, auth files, or nothing
|
||||
5. Exact next command to start DeerFlow
|
||||
|
||||
## EXECUTE NOW
|
||||
|
||||
Complete the steps above. When finished, stop after the setup boundary and report status instead of continuing into unrelated project work.

## One-Line Agent Setup
|
||||
|
||||
If you use Claude Code, Codex, Cursor, Windsurf, or another coding agent, you can hand it the setup instructions in one sentence:
|
||||
|
||||
```text
|
||||
Help me clone DeerFlow if needed, then bootstrap it for local development by following https://raw.githubusercontent.com/bytedance/deer-flow/main/Install.md
|
||||
```
|
||||
|
||||
That prompt is intended for coding agents. It tells the agent to clone the repo if needed, choose Docker when available, and stop with the exact next command plus any missing config the user still needs to provide.
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Configuration
|

@@ -104,149 +57,74 @@ That prompt is intended for coding agents. It tells the agent to clone the repo
|
||||
cd deer-flow
|
||||
```
|
||||
|
||||
2. **Run the setup wizard**
|
||||
2. **Generate local configuration files**
|
||||
|
||||
From the project root directory (`deer-flow/`), run:
|
||||
|
||||
```bash
|
||||
make setup
|
||||
make config
|
||||
```
|
||||
|
||||
This launches an interactive wizard that guides you through choosing an LLM provider, optional web search, and execution/safety preferences such as sandbox mode, bash access, and file-write tools. It generates a minimal `config.yaml` and writes your keys to `.env`. Takes about 2 minutes.
|
||||
This command creates local configuration files based on the provided example templates.
|
||||
|
||||
The wizard also lets you configure an optional web search provider, or skip it for now.
|
||||
3. **Configure your preferred model(s)**
|
||||
|
||||
Run `make doctor` at any time to verify your setup and get actionable fix hints.
|
||||
|
||||
> **Advanced / manual configuration**: If you prefer to edit `config.yaml` directly, run `make config` instead to copy the full template. See `config.example.yaml` for the complete reference including CLI-backed providers (Codex CLI, Claude Code OAuth), OpenRouter, Responses API, and more.
|
||||
|
||||
<details>
|
||||
<summary>Manual model configuration examples</summary>
|
||||
Edit `config.yaml` and define at least one model:
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-4o
|
||||
display_name: GPT-4o
|
||||
use: langchain_openai:ChatOpenAI
|
||||
model: gpt-4o
|
||||
api_key: $OPENAI_API_KEY
|
||||
|
||||
- name: openrouter-gemini-2.5-flash
|
||||
display_name: Gemini 2.5 Flash (OpenRouter)
|
||||
use: langchain_openai:ChatOpenAI
|
||||
model: google/gemini-2.5-flash-preview
|
||||
api_key: $OPENROUTER_API_KEY
|
||||
base_url: https://openrouter.ai/api/v1
|
||||
|
||||
- name: gpt-5-responses
|
||||
display_name: GPT-5 (Responses API)
|
||||
use: langchain_openai:ChatOpenAI
|
||||
model: gpt-5
|
||||
api_key: $OPENAI_API_KEY
|
||||
use_responses_api: true
|
||||
output_version: responses/v1
|
||||
|
||||
- name: qwen3-32b-vllm
|
||||

|
||||
use: deerflow.models.vllm_provider:VllmChatModel
|
||||
model: Qwen/Qwen3-32B
|
||||
api_key: $VLLM_API_KEY
|
||||
base_url: http://localhost:8000/v1
|
||||
supports_thinking: true
|
||||
when_thinking_enabled:
|
||||
extra_body:
|
||||
chat_template_kwargs:
|
||||
enable_thinking: true
|
||||
- name: gpt-4 # Internal identifier
|
||||
display_name: GPT-4 # Human-readable name
|
||||
use: langchain_openai:ChatOpenAI # LangChain class path
|
||||
model: gpt-4 # Model identifier for API
|
||||
api_key: $OPENAI_API_KEY # API key (recommended: use env var)
|
||||
max_tokens: 4096 # Maximum tokens per request
|
||||
temperature: 0.7 # Sampling temperature
|
||||
```
|
||||
|
||||
OpenRouter and similar OpenAI-compatible gateways should be configured with `langchain_openai:ChatOpenAI` plus `base_url`. If you prefer a provider-specific environment variable name, point `api_key` at that variable explicitly (for example `api_key: $OPENROUTER_API_KEY`).
|
||||
|
||||
4. **Set API keys for your configured model(s)**
|
||||
|
||||
To route OpenAI models through `/v1/responses`, keep using `langchain_openai:ChatOpenAI` and set `use_responses_api: true` with `output_version: responses/v1`.
|
||||
Choose one of the following methods:
|
||||
|
||||
For vLLM 0.19.0, use `deerflow.models.vllm_provider:VllmChatModel`. For Qwen-style reasoning models, DeerFlow toggles reasoning with `extra_body.chat_template_kwargs.enable_thinking` and preserves vLLM's non-standard `reasoning` field across multi-turn tool-call conversations. Legacy `thinking` configs are normalized automatically for backward compatibility. Reasoning models may also require the server to be started with `--reasoning-parser ...`. If your local vLLM deployment accepts any non-empty API key, you can still set `VLLM_API_KEY` to a placeholder value.
|
||||
- Option A: Edit the `.env` file in the project root (Recommended)
|
||||
|
||||
CLI-backed provider examples:
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-5.4
|
||||
display_name: GPT-5.4 (Codex CLI)
|
||||
use: deerflow.models.openai_codex_provider:CodexChatModel
|
||||
model: gpt-5.4
|
||||
supports_thinking: true
|
||||
supports_reasoning_effort: true
|
||||
|
||||
- name: claude-sonnet-4.6
|
||||
display_name: Claude Sonnet 4.6 (Claude Code OAuth)
|
||||
use: deerflow.models.claude_provider:ClaudeChatModel
|
||||
model: claude-sonnet-4-6
|
||||
max_tokens: 4096
|
||||
supports_thinking: true
|
||||
```
|
||||
|
||||
- Codex CLI reads `~/.codex/auth.json`
|
||||
- Claude Code accepts `CLAUDE_CODE_OAUTH_TOKEN`, `ANTHROPIC_AUTH_TOKEN`, `CLAUDE_CODE_CREDENTIALS_PATH`, or `~/.claude/.credentials.json`
|
||||
- ACP agent entries are separate from model providers — if you configure `acp_agents.codex`, point it at a Codex ACP adapter such as `npx -y @zed-industries/codex-acp`
|
||||
- On macOS, export Claude Code auth explicitly if needed:
|
||||
|
||||
```bash
|
||||
eval "$(python3 scripts/export_claude_code_oauth.py --print-export)"
|
||||
```
|
||||
|
||||
API keys can also be set manually in `.env` (recommended) or exported in your shell:
|
||||
|
||||
```bash
|
||||
OPENAI_API_KEY=your-openai-api-key
|
||||
TAVILY_API_KEY=your-tavily-api-key
|
||||
OPENAI_API_KEY=your-openai-api-key
|
||||
# Add other provider keys as needed
|
||||
```
|
||||
|
||||
</details>
|
||||
- Option B: Export environment variables in your shell
|
||||
|
||||
```bash
|
||||
export OPENAI_API_KEY=your-openai-api-key
|
||||
```
|
||||
|
||||
- Option C: Edit `config.yaml` directly (Not recommended for production)
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-4
|
||||
api_key: your-actual-api-key-here # Replace placeholder
|
||||
```
|
||||
|
||||
### Running the Application
|
||||
|
||||
#### Deployment Sizing
|
||||
|
||||
Use the table below as a practical starting point when choosing how to run DeerFlow:
|
||||
|
||||
| Deployment target | Starting point | Recommended | Notes |
|
||||
|---------|-----------|------------|-------|
|
||||
| Local evaluation / `make dev` | 4 vCPU, 8 GB RAM, 20 GB free SSD | 8 vCPU, 16 GB RAM | Good for one developer or one light session with hosted model APIs. `2 vCPU / 4 GB` is usually not enough. |
|
||||
| Docker development / `make docker-start` | 4 vCPU, 8 GB RAM, 25 GB free SSD | 8 vCPU, 16 GB RAM | Image builds, bind mounts, and sandbox containers need more headroom than pure local dev. |
|
||||
| Long-running server / `make up` | 8 vCPU, 16 GB RAM, 40 GB free SSD | 16 vCPU, 32 GB RAM | Preferred for shared use, multi-agent runs, report generation, or heavier sandbox workloads. |
|
||||
|
||||
- These numbers cover DeerFlow itself. If you also host a local LLM, size that service separately.
|
||||
- Linux plus Docker is the recommended deployment target for a persistent server. macOS and Windows are best treated as development or evaluation environments.
|
||||
- If CPU or memory usage stays pinned, reduce concurrent runs first, then move to the next sizing tier.
|
||||
|
||||
#### Option 1: Docker (Recommended)
|
||||
|
||||
**Development** (hot-reload, source mounts):
|
||||
The fastest way to get started with a consistent environment:
|
||||
|
||||
```bash
|
||||
make docker-init # Pull sandbox image (only once or when image updates)
|
||||
make docker-start # Start services (auto-detects sandbox mode from config.yaml)
|
||||
```
|
||||
1. **Initialize and start**:
|
||||
```bash
|
||||
make docker-init # Pull sandbox image (Only once or when image updates)
|
||||
make docker-start # Start services (auto-detects sandbox mode from config.yaml)
|
||||
```
|
||||
|
||||
`make docker-start` starts `provisioner` only when `config.yaml` uses provisioner mode (`sandbox.use: deerflow.community.aio_sandbox:AioSandboxProvider` with `provisioner_url`).
|
||||
`make docker-start` now starts `provisioner` only when `config.yaml` uses provisioner mode (`sandbox.use: src.community.aio_sandbox:AioSandboxProvider` with `provisioner_url`).
|
||||
|
||||
Docker builds use the upstream `uv` registry by default. If you need faster mirrors in restricted networks, export `UV_INDEX_URL=https://pypi.tuna.tsinghua.edu.cn/simple` and `NPM_REGISTRY=https://registry.npmmirror.com` before running `make docker-init` or `make docker-start`.
|
||||
|
||||
Backend processes automatically pick up `config.yaml` changes on the next config access, so model metadata updates do not require a manual restart during development.
|
||||
|
||||
> [!TIP]
|
||||
> On Linux, if Docker-based commands fail with `permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock`, add your user to the `docker` group and re-login before retrying. See [CONTRIBUTING.md](CONTRIBUTING.md#linux-docker-daemon-permission-denied) for the full fix.
|
||||
|
||||
**Production** (builds images locally, mounts runtime config and data):
|
||||
|
||||
```bash
|
||||
make up # Build images and start all production services
|
||||
make down # Stop and remove containers
|
||||
```

#### Startup Modes
|
||||
|
||||
DeerFlow supports multiple startup modes across two dimensions:
|
||||
|
||||
- **Dev / Prod** — dev enables hot-reload; prod uses pre-built frontend
|
||||
- **Standard / Gateway** — standard uses a separate LangGraph server (4 processes); Gateway mode (experimental) embeds the agent runtime in the Gateway API (3 processes)
|
||||
|
||||
| | **Local Foreground** | **Local Daemon** | **Docker Dev** | **Docker Prod** |
|
||||
|---|---|---|---|---|
|
||||
| **Dev** | `./scripts/serve.sh --dev`<br/>`make dev` | `./scripts/serve.sh --dev --daemon`<br/>`make dev-daemon` | `./scripts/docker.sh start`<br/>`make docker-start` | — |
|
||||
| **Dev + Gateway** | `./scripts/serve.sh --dev --gateway`<br/>`make dev-pro` | `./scripts/serve.sh --dev --gateway --daemon`<br/>`make dev-daemon-pro` | `./scripts/docker.sh start --gateway`<br/>`make docker-start-pro` | — |

|
||||
> **Gateway mode** eliminates the LangGraph server process — the Gateway API handles agent execution directly via async tasks, managing its own concurrency.
|
||||
|
||||
#### Why Gateway Mode?
|
||||
|
||||
In standard mode, DeerFlow runs a dedicated [LangGraph Platform](https://langchain-ai.github.io/langgraph/) server alongside the Gateway API. This architecture works well but has trade-offs:
|
||||
|
||||
| | Standard Mode | Gateway Mode |
|
||||
|---|---|---|
|
||||
| **Architecture** | Gateway (REST API) + LangGraph (agent runtime) | Gateway embeds agent runtime |
|
||||
| **Concurrency** | `--n-jobs-per-worker` per worker (requires license) | `--workers` × async tasks (no per-worker cap) |
|
||||
| **Containers / Processes** | 4 (frontend, gateway, langgraph, nginx) | 3 (frontend, gateway, nginx) |
|
||||
| **Resource usage** | Higher (two Python runtimes) | Lower (single Python runtime) |
|
||||
| **LangGraph Platform license** | Required for production images | Not required |
|
||||
| **Cold start** | Slower (two services to initialize) | Faster |
|
||||
|
||||
Both modes are functionally equivalent — the same agents, tools, and skills work in either mode.
|
||||
|
||||
#### Docker Production Deployment
|
||||
|
||||
`deploy.sh` supports building and starting separately. Images are mode-agnostic — runtime mode is selected at start time:
|
||||
|
||||
```bash
|
||||
# One-step (build + start)
|
||||
deploy.sh # standard mode (default)
|
||||
deploy.sh --gateway # gateway mode
|
||||
|
||||
# Two-step (build once, start with any mode)
|
||||
deploy.sh build # build all images
|
||||
deploy.sh start # start in standard mode
|
||||
deploy.sh start --gateway # start in gateway mode
|
||||
|
||||
# Stop
|
||||
deploy.sh down

||||
```

Notes:
|
||||
- `assistant_id: lead_agent` calls the default LangGraph assistant directly.
|
||||
- If `assistant_id` is set to a custom agent name, DeerFlow still routes through `lead_agent` and injects that value as `agent_name`, so the custom agent's SOUL/config takes effect for IM channels.
|
||||
|
||||
Set the corresponding API keys in your `.env` file:

||||

```
|
||||
|
||||
**Telegram Setup**
|
||||
|
||||
1. Chat with [@BotFather](https://t.me/BotFather), send `/newbot`, and copy the HTTP API token.
|
||||
2. Set `TELEGRAM_BOT_TOKEN` in `.env` and enable the channel in `config.yaml`.
|
||||
|
||||
**Slack Setup**
|
||||
|
||||
1. Create a Slack App at [api.slack.com/apps](https://api.slack.com/apps) → Create New App → From scratch.
|
||||
2. Under **OAuth & Permissions**, add Bot Token Scopes: `app_mentions:read`, `chat:write`, `im:history`, `im:read`, `im:write`, `files:write`.
|
||||
3. Enable **Socket Mode** → generate an App-Level Token (`xapp-…`) with `connections:write` scope.
|
||||
4. Under **Event Subscriptions**, subscribe to bot events: `app_mention`, `message.im`.
|
||||
5. Set `SLACK_BOT_TOKEN` and `SLACK_APP_TOKEN` in `.env` and enable the channel in `config.yaml`.
|
||||
|
||||
**Feishu / Lark Setup**
|
||||
|
||||
1. Create an app on [Feishu Open Platform](https://open.feishu.cn/) → enable **Bot** capability.
|
||||
2. Add permissions: `im:message`, `im:message.p2p_msg:readonly`, `im:resource`.
|
||||
3. Under **Events**, subscribe to `im.message.receive_v1` and select **Long Connection** mode.
|
||||
4. Copy the App ID and App Secret. Set `FEISHU_APP_ID` and `FEISHU_APP_SECRET` in `.env` and enable the channel in `config.yaml`.
|
||||
|
||||
**WeChat Setup**
|
||||
|
||||
1. Enable the `wechat` channel in `config.yaml`.
|
||||
2. Either set `WECHAT_BOT_TOKEN` in `.env`, or set `qrcode_login_enabled: true` for first-time QR bootstrap.
|
||||
3. When `bot_token` is absent and QR bootstrap is enabled, watch backend logs for the QR content returned by iLink and complete the binding flow.
|
||||
4. After the QR flow succeeds, DeerFlow persists the acquired token under `state_dir` for later restarts.
|
||||
5. For Docker Compose deployments, keep `state_dir` on a persistent volume so the `get_updates_buf` cursor and saved auth state survive restarts.
|
||||
|
||||
**WeCom Setup**
|
||||
|
||||
1. Create a bot on the WeCom AI Bot platform and obtain the `bot_id` and `bot_secret`.
|
||||
2. Enable `channels.wecom` in `config.yaml` and fill in `bot_id` / `bot_secret`.
|
||||
3. Set `WECOM_BOT_ID` and `WECOM_BOT_SECRET` in `.env`.
|
||||
4. Make sure backend dependencies include `wecom-aibot-python-sdk`. The channel uses a WebSocket long connection and does not require a public callback URL.
|
||||
5. The current integration supports inbound text, image, and file messages. Final images/files generated by the agent are also sent back to the WeCom conversation.
|
||||
|
||||
When DeerFlow runs in Docker Compose, IM channels execute inside the `gateway` container. In that case, do not point `channels.langgraph_url` or `channels.gateway_url` at `localhost`; use container service names such as `http://langgraph:2024` and `http://gateway:8001`, or set `DEER_FLOW_CHANNELS_LANGGRAPH_URL` and `DEER_FLOW_CHANNELS_GATEWAY_URL`.
|
||||
|
||||
**Commands**
|
||||
|
||||
Once a channel is connected, you can interact with DeerFlow directly from the chat:
|
||||
|
||||
| Command | Description |
|
||||
|---------|-------------|
|
||||
| `/new` | Start a new conversation |
|
||||
| `/status` | Show current thread info |
|
||||
| `/models` | List available models |
|
||||
| `/memory` | View memory |
|
||||
| `/help` | Show help |
|
||||
|
||||
> Messages without a command prefix are treated as regular chat — DeerFlow creates a thread and responds conversationally.
|
||||
|
||||
#### LangSmith Tracing
|
||||
|
||||
DeerFlow has built-in [LangSmith](https://smith.langchain.com) integration for observability. When enabled, all LLM calls, agent runs, and tool executions are traced and visible in the LangSmith dashboard.
|
||||
|
||||
Add the following to your `.env` file:
|
||||
|
||||
```bash
|
||||
LANGSMITH_TRACING=true
|
||||
LANGSMITH_ENDPOINT=https://api.smith.langchain.com
|
||||
LANGSMITH_API_KEY=lsv2_pt_xxxxxxxxxxxxxxxx
|
||||
LANGSMITH_PROJECT=xxx
|
||||
```
|
||||
|
||||
#### Langfuse Tracing
|
||||
|
||||
DeerFlow also supports [Langfuse](https://langfuse.com) observability for LangChain-compatible runs.
|
||||
|
||||
Add the following to your `.env` file:
|
||||
|
||||
```bash
|
||||
LANGFUSE_TRACING=true
|
||||
LANGFUSE_PUBLIC_KEY=pk-lf-xxxxxxxxxxxxxxxx
|
||||
LANGFUSE_SECRET_KEY=sk-lf-xxxxxxxxxxxxxxxx
|
||||
LANGFUSE_BASE_URL=https://cloud.langfuse.com
|
||||
```
|
||||
|
||||
If you are using a self-hosted Langfuse instance, set `LANGFUSE_BASE_URL` to your deployment URL.
|
||||
|
||||
#### Using Both Providers
|
||||
|
||||
If both LangSmith and Langfuse are enabled, DeerFlow attaches both tracing callbacks and reports the same model activity to both systems.
|
||||
|
||||
If a provider is explicitly enabled but missing required credentials, or if its callback fails to initialize, DeerFlow fails fast when tracing is initialized during model creation and the error message names the provider that caused the failure.
|
||||
|
||||
For Docker deployments, tracing is disabled by default. Set `LANGSMITH_TRACING=true` and `LANGSMITH_API_KEY` in your `.env` to enable it.

Each task gets its own execution environment with a full filesystem view — skills, workspace, uploads, outputs. The agent reads, writes, and edits files. It can view images and, when configured safely, execute shell commands.
|
||||
|
||||
With `AioSandboxProvider`, shell execution runs inside isolated containers. With `LocalSandboxProvider`, file tools still map to per-thread directories on the host, but host `bash` is disabled by default because it is not a secure isolation boundary. Re-enable host bash only for fully trusted local workflows.

Each task runs inside an isolated Docker container with a full filesystem — skills, workspace, uploads, outputs. The agent reads, writes, and edits files. It executes bash commands and codes. It views images. All sandboxed, all auditable, zero contamination between sessions.

Across sessions, DeerFlow builds a persistent memory of your profile, preferences, and accumulated knowledge. The more you use it, the better it knows you — your writing style, your technical stack, your recurring workflows. Memory is stored locally and stays under your control.

## Embedded Python Client

DeerFlow can be used as an embedded Python library without running the full HTTP services. The `DeerFlowClient` provides direct in-process access to all agent and Gateway capabilities, returning the same response schemas as the HTTP Gateway API. The HTTP Gateway also exposes `DELETE /api/threads/{thread_id}` to remove DeerFlow-managed local thread data after the LangGraph thread itself has been deleted:

## ⚠️ Security Notice
|
||||
|
||||
### Improper Deployment May Introduce Security Risks
|
||||
|
||||
DeerFlow has key high-privilege capabilities including **system command execution, resource operations, and business logic invocation**, and is designed by default to be **deployed in a local trusted environment (accessible only via the 127.0.0.1 loopback interface)**. If you deploy the agent in untrusted environments — such as LAN networks, public cloud servers, or other multi-endpoint accessible environments — without strict security measures, it may introduce security risks, including:
|
||||
|
||||
- **Unauthorized illegal invocation**: Agent functionality could be discovered by unauthorized third parties or malicious internet scanners, triggering bulk unauthorized requests that execute high-risk operations such as system commands and file read/write, potentially causing serious security consequences.
|
||||
- **Compliance and legal risks**: If the agent is illegally invoked to conduct cyberattacks, data theft, or other illegal activities, it may result in legal liability and compliance risks.
|
||||
|
||||
### Security Recommendations
|
||||
|
||||
**Note: We strongly recommend deploying DeerFlow in a local trusted network environment.** If you need cross-device or cross-network deployment, you must implement strict security measures, such as:
|
||||
|
||||
- **IP allowlist**: Use `iptables`, or deploy hardware firewalls / switches with Access Control Lists (ACL), to **configure IP allowlist rules** and deny access from all other IP addresses.
|
||||
- **Authentication gateway**: Configure a reverse proxy (e.g., nginx) and **enable strong pre-authentication**, blocking any unauthenticated access.
|
||||
- **Network isolation**: Where possible, place the agent and trusted devices in the **same dedicated VLAN**, isolated from other network devices.
|
||||
- **Stay updated**: Continue to follow DeerFlow's security feature updates.

||||

We welcome contributions! Please see [CONTRIBUTING.md](CONTRIBUTING.md) for development setup, workflow, and guidelines.
|
||||
|
||||
Regression coverage includes Docker sandbox mode detection and provisioner kubeconfig-path handling tests in `backend/tests/`.
|
||||
Gateway artifact serving now forces active web content types (`text/html`, `application/xhtml+xml`, `image/svg+xml`) to download as attachments instead of inline rendering, reducing XSS risk for generated artifacts.

## Installation en une phrase pour un coding agent
|
||||
|
||||
Si vous utilisez Claude Code, Codex, Cursor, Windsurf ou un autre coding agent, vous pouvez simplement lui envoyer cette phrase :
|
||||
|
||||
```text
|
||||
Aide-moi à cloner DeerFlow si nécessaire, puis à initialiser son environnement de développement local en suivant https://raw.githubusercontent.com/bytedance/deer-flow/main/Install.md
|
||||
```
|
||||
|
||||
Ce prompt est destiné aux coding agents. Il leur demande de cloner le dépôt si nécessaire, de privilégier Docker quand il est disponible, puis de s'arrêter avec la commande exacte pour lancer DeerFlow et la liste des configurations encore manquantes.
|
||||
|
||||
## Démarrage rapide
|
||||
|
||||
### Configuration
|
||||
|
||||
1. **Cloner le dépôt DeerFlow**
|
||||
|
||||
```bash
|
||||
git clone https://github.com/bytedance/deer-flow.git
|
||||
cd deer-flow
|
||||
```
|
||||
|
||||
2. **Générer les fichiers de configuration locaux**
|
||||
|
||||
Depuis le répertoire racine du projet (`deer-flow/`), exécutez :
|
||||
|
||||
```bash
|
||||
make config
|
||||
```
|
||||
|
||||
Cette commande crée les fichiers de configuration locaux à partir des templates fournis.
|
||||
|
||||
3. **Configurer le(s) modèle(s) de votre choix**
|
||||
|
||||
Éditez `config.yaml` et définissez au moins un modèle :
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-4 # Internal identifier
|
||||
display_name: GPT-4 # Human-readable name
|
||||
use: langchain_openai:ChatOpenAI # LangChain class path
|
||||
model: gpt-4 # Model identifier for API
|
||||
api_key: $OPENAI_API_KEY # API key (recommended: use env var)
|
||||
max_tokens: 4096 # Maximum tokens per request
|
||||
temperature: 0.7 # Sampling temperature
|
||||
|
||||
- name: openrouter-gemini-2.5-flash
|
||||
display_name: Gemini 2.5 Flash (OpenRouter)
|
||||
use: langchain_openai:ChatOpenAI
|
||||
model: google/gemini-2.5-flash-preview
|
||||
api_key: $OPENAI_API_KEY # OpenRouter still uses the OpenAI-compatible field name here
|
||||
base_url: https://openrouter.ai/api/v1
|
||||
|
||||
- name: gpt-5-responses
|
||||
display_name: GPT-5 (Responses API)
|
||||
use: langchain_openai:ChatOpenAI
|
||||
model: gpt-5
|
||||
api_key: $OPENAI_API_KEY
|
||||
use_responses_api: true
|
||||
output_version: responses/v1
|
||||
```
|
||||
|
||||
OpenRouter et les passerelles compatibles OpenAI similaires doivent être configurés avec `langchain_openai:ChatOpenAI` et `base_url`. Si vous préférez utiliser un nom de variable d'environnement propre au fournisseur, pointez `api_key` vers cette variable explicitement (par exemple `api_key: $OPENROUTER_API_KEY`).
|
||||
|
||||
Pour router les modèles OpenAI via `/v1/responses`, continuez d'utiliser `langchain_openai:ChatOpenAI` et définissez `use_responses_api: true` avec `output_version: responses/v1`.
|
||||
|
||||
Exemples de providers basés sur un CLI :
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-5.4
|
||||
display_name: GPT-5.4 (Codex CLI)
|
||||
use: deerflow.models.openai_codex_provider:CodexChatModel
|
||||
model: gpt-5.4
|
||||
supports_thinking: true
|
||||
supports_reasoning_effort: true
|
||||
|
||||
- name: claude-sonnet-4.6
|
||||
display_name: Claude Sonnet 4.6 (Claude Code OAuth)
|
||||
use: deerflow.models.claude_provider:ClaudeChatModel
|
||||
model: claude-sonnet-4-6
|
||||
max_tokens: 4096
|
||||
supports_thinking: true
|
||||
```
|
||||
|
||||
- Codex CLI lit `~/.codex/auth.json`
|
||||
- L'endpoint Responses de Codex rejette actuellement `max_tokens` et `max_output_tokens`, donc `CodexChatModel` n'expose pas de limite de tokens par requête
|
||||
- Claude Code accepte `CLAUDE_CODE_OAUTH_TOKEN`, `ANTHROPIC_AUTH_TOKEN`, `CLAUDE_CODE_OAUTH_TOKEN_FILE_DESCRIPTOR`, `CLAUDE_CODE_CREDENTIALS_PATH`, ou en clair `~/.claude/.credentials.json`
|
||||
- Sur macOS, DeerFlow ne sonde pas le Keychain automatiquement. Exportez l'auth Claude Code explicitement si nécessaire :
|
||||
|
||||
```bash
|
||||
eval "$(python3 scripts/export_claude_code_oauth.py --print-export)"
|
||||
```
|
||||
|
||||
4. **Définir les clés API pour le(s) modèle(s) configuré(s)**
|
||||
|
||||
Choisissez l'une des méthodes suivantes :
|
||||
|
||||
- Option A : Éditer le fichier `.env` à la racine du projet (recommandé)
|
||||
|
||||
|
||||
```bash
|
||||
TAVILY_API_KEY=your-tavily-api-key
|
||||
OPENAI_API_KEY=your-openai-api-key
|
||||
# OpenRouter also uses OPENAI_API_KEY when your config uses langchain_openai:ChatOpenAI + base_url.
|
||||
# Add other provider keys as needed
|
||||
INFOQUEST_API_KEY=your-infoquest-api-key
|
||||
```
|
||||
|
||||
- Option B : Exporter les variables d'environnement dans votre shell
|
||||
|
||||
```bash
|
||||
export OPENAI_API_KEY=your-openai-api-key
|
||||
```
|
||||
|
||||
Pour les providers basés sur un CLI :
|
||||
- Codex CLI : `~/.codex/auth.json`
|
||||
- Claude Code OAuth : handoff explicite via env/fichier ou `~/.claude/.credentials.json`
|
||||
|
||||
- Option C : Éditer `config.yaml` directement (non recommandé en production)
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-4
|
||||
api_key: your-actual-api-key-here # Replace placeholder
|
||||
```
|
||||
|
||||
### Lancer l'application
|
||||
|
||||
#### Option 1 : Docker (recommandé)
|
||||
|
||||
**Développement** (hot-reload, montage des sources) :
|
||||
|
||||
```bash
|
||||
make docker-init # Pull sandbox image (only once or when image updates)
|
||||
make docker-start # Start services (auto-detects sandbox mode from config.yaml)
|
||||
```
|
||||
|
||||
`make docker-start` ne lance `provisioner` que si `config.yaml` utilise le mode provisioner (`sandbox.use: deerflow.community.aio_sandbox:AioSandboxProvider` avec `provisioner_url`).
|
||||
Les processus backend récupèrent automatiquement les changements dans `config.yaml` au prochain accès à la configuration, donc les mises à jour de métadonnées des modèles ne nécessitent pas de redémarrage manuel en développement.
|
||||
|
||||
> [!TIP]
|
||||
> Sous Linux, si les commandes Docker échouent avec `permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock`, ajoutez votre utilisateur au groupe `docker` et reconnectez-vous avant de réessayer. Voir [CONTRIBUTING.md](CONTRIBUTING.md#linux-docker-daemon-permission-denied) pour la solution complète.
|
||||
|
||||
**Production** (build des images en local, montage de la config et des données) :
|
||||
|
||||
```bash
|
||||
make up # Build images and start all production services
|
||||
make down # Stop and remove containers
|
||||
```
|
||||
|
||||
> [!NOTE]
|
||||
> Le serveur d'agents LangGraph fonctionne actuellement via `langgraph dev` (le serveur CLI open source).
|
||||
|
||||
Accès : http://localhost:2026
|
||||
|
||||
Voir [CONTRIBUTING.md](CONTRIBUTING.md) pour le guide complet de développement avec Docker.
|
||||
|
||||
#### Option 2 : Développement local
|
||||
|
||||
Si vous préférez lancer les services en local :
|
||||
|
||||
Prérequis : complétez d'abord les étapes de « Configuration » ci-dessus (`make config` et clés API des modèles). `make dev` nécessite un fichier de configuration valide (par défaut `config.yaml` à la racine du projet ; modifiable via `DEER_FLOW_CONFIG_PATH`).
|
||||
|
||||
1. **Vérifier les prérequis** :
|
||||
```bash
|
||||
make check # Verifies Node.js 22+, pnpm, uv, nginx
|
||||
```
|
||||
|
||||
2. **Installer les dépendances** :
|
||||
```bash
|
||||
make install # Install backend + frontend dependencies
|
||||
```
|
||||
|
||||
3. **(Optionnel) Pré-télécharger l'image sandbox** :
|
||||
```bash
|
||||
# Recommended if using Docker/Container-based sandbox
|
||||
make setup-sandbox
|
||||
```
|
||||
|
||||
4. **Démarrer les services** :
|
||||
```bash
|
||||
make dev
|
||||
```
|
||||
|
||||
5. **Accès** : http://localhost:2026
|
||||
|
||||
### Avancé
|
||||
#### Mode Sandbox
|
||||
|
||||
DeerFlow supporte plusieurs modes d'exécution sandbox :
|
||||
- **Exécution locale** (exécute le code sandbox directement sur la machine hôte)
|
||||
- **Exécution Docker** (exécute le code sandbox dans des conteneurs Docker isolés)
|
||||
- **Exécution Docker avec Kubernetes** (exécute le code sandbox dans des pods Kubernetes via le service provisioner)
|
||||
|
||||
En développement Docker, le démarrage des services suit le mode sandbox défini dans `config.yaml`. En mode Local/Docker, `provisioner` n'est pas démarré.
|
||||
|
||||
Voir le [Guide de configuration Sandbox](backend/docs/CONFIGURATION.md#sandbox) pour configurer le mode de votre choix.
|
||||
|
||||
#### Serveur MCP
|
||||
|
||||
DeerFlow supporte des serveurs MCP et des skills configurables pour étendre ses capacités.
|
||||
Pour les serveurs MCP HTTP/SSE, les flux de tokens OAuth sont supportés (`client_credentials`, `refresh_token`).
|
||||
Voir le [Guide MCP Server](backend/docs/MCP_SERVER.md) pour les instructions détaillées.
|
||||
|
||||
#### Canaux de messagerie
|
||||
|
||||
DeerFlow peut recevoir des tâches depuis des applications de messagerie. Les canaux démarrent automatiquement une fois configurés — aucune IP publique n'est requise.
|
||||
|
||||
| Canal | Transport | Difficulté |
|
||||

|
||||
FEISHU_APP_SECRET=your_app_secret
|
||||
```
|
||||
|
||||
**Configuration Telegram**
|
||||
|
||||
1. Ouvrez une conversation avec [@BotFather](https://t.me/BotFather), envoyez `/newbot`, et copiez le token HTTP API.
|
||||
2. Définissez `TELEGRAM_BOT_TOKEN` dans `.env` et activez le canal dans `config.yaml`.
|
||||
|
||||
**Configuration Slack**
|
||||
|
||||
1. Créez une Slack App sur [api.slack.com/apps](https://api.slack.com/apps) → Create New App → From scratch.
|
||||
2. Dans **OAuth & Permissions**, ajoutez les Bot Token Scopes : `app_mentions:read`, `chat:write`, `im:history`, `im:read`, `im:write`, `files:write`.
|
||||
3. Activez le **Socket Mode** → générez un App-Level Token (`xapp-…`) avec le scope `connections:write`.
|
||||
4. Dans **Event Subscriptions**, abonnez-vous aux bot events : `app_mention`, `message.im`.
|
||||
5. Définissez `SLACK_BOT_TOKEN` et `SLACK_APP_TOKEN` dans `.env` et activez le canal dans `config.yaml`.
|
||||
|
||||
**Configuration Feishu / Lark**
|
||||
|
||||
1. Créez une application sur [Feishu Open Platform](https://open.feishu.cn/) → activez la capacité **Bot**.
|
||||
2. Ajoutez les permissions : `im:message`, `im:message.p2p_msg:readonly`, `im:resource`.
|
||||
3. Dans **Events**, abonnez-vous à `im.message.receive_v1` et sélectionnez le mode **Long Connection**.
|

|
||||
| `/memory` | Consulter la mémoire |
|
||||
| `/help` | Afficher l'aide |
|
||||
|
||||
> Les messages sans préfixe de commande sont traités comme du chat classique — DeerFlow crée un thread et répond de manière conversationnelle.
|
||||
|
||||
#### Traçage LangSmith
|
||||
|
||||
DeerFlow intègre nativement [LangSmith](https://smith.langchain.com) pour l'observabilité. Une fois activé, tous les appels LLM, les exécutions d'agents et les exécutions d'outils sont tracés et visibles dans le tableau de bord LangSmith.
|
||||
|
||||
Ajoutez les lignes suivantes à votre fichier `.env` :
|
||||
|
||||
```bash
|
||||
LANGSMITH_TRACING=true
|
||||
LANGSMITH_ENDPOINT=https://api.smith.langchain.com
|
||||
LANGSMITH_API_KEY=lsv2_pt_xxxxxxxxxxxxxxxx
|
||||
LANGSMITH_PROJECT=xxx
|
||||
```
|
||||
|
||||
Pour les déploiements Docker, le traçage est désactivé par défaut. Définissez `LANGSMITH_TRACING=true` et `LANGSMITH_API_KEY` dans votre `.env` pour l'activer.

||||
## Du Deep Research au Super Agent Harness
|
||||
|
||||
DeerFlow a démarré comme un framework de Deep Research — et la communauté s'en est emparée. Depuis le lancement, les développeurs l'ont poussé bien au-delà de la recherche : construction de pipelines de données, génération de présentations, mise en place de dashboards, automatisation de workflows de contenu. Des usages qu'on n'avait jamais anticipés.
|
||||
|
||||
Ça nous a révélé quelque chose d'important : DeerFlow n'était pas qu'un simple outil de recherche. C'était un **harness** — un runtime qui donne aux agents l'infrastructure nécessaire pour vraiment accomplir du travail.
|
||||
|
||||
On l'a donc reconstruit de zéro.
|
||||
|
||||
DeerFlow 2.0 n'est plus un framework à assembler soi-même. C'est un super agent harness — clé en main et entièrement extensible. Construit sur LangGraph et LangChain, il embarque tout ce dont un agent a besoin out of the box : un système de fichiers, de la mémoire, des skills, une exécution sandboxée, et la capacité de planifier et de lancer des sub-agents pour les tâches complexes et multi-étapes.
|
||||
|
||||
Utilisez-le tel quel. Ou démontez-le et faites-en le vôtre.
|
||||
|
||||
## Fonctionnalités principales
|
||||
|
||||
### Skills et outils
|
||||
|
||||
Les skills sont ce qui permet à DeerFlow de faire *pratiquement n'importe quoi*.
|
||||
|
||||
Un Agent Skill standard est un module de capacité structuré — un fichier Markdown qui définit un workflow, des bonnes pratiques et des références vers des ressources associées. DeerFlow est livré avec des skills intégrés pour la recherche, la génération de rapports, la création de présentations, les pages web, la génération d'images et de vidéos, et bien plus. Mais la vraie force réside dans l'extensibilité : ajoutez vos propres skills, remplacez ceux fournis, ou combinez-les en workflows composites.
|
||||
|
||||
Les skills sont chargés progressivement — uniquement quand la tâche le nécessite, pas tous en même temps. Ça permet de garder la fenêtre de contexte légère et de bien fonctionner même avec des modèles sensibles au nombre de tokens.
|
||||
|
||||
Quand vous installez des archives `.skill` via le Gateway, DeerFlow accepte les métadonnées frontmatter optionnelles standard comme `version`, `author` et `compatibility`, plutôt que de rejeter des skills externes par ailleurs valides.
|
||||
|
||||
Les outils suivent la même philosophie. DeerFlow est livré avec un ensemble d'outils de base — recherche web, fetch de pages web, opérations sur les fichiers, exécution bash — et supporte les outils custom via des serveurs MCP et des fonctions Python. Remplacez n'importe quoi. Ajoutez n'importe quoi.
|
||||
|
||||
Les suggestions de suivi générées par le Gateway normalisent désormais aussi bien la sortie texte brut du modèle que le contenu riche au format bloc/liste avant de parser la réponse en tableau JSON, de sorte que les wrappers de contenu propres à chaque provider ne suppriment plus silencieusement les suggestions.
|

|
||||
```
|
||||
|
||||
#### Intégration Claude Code
|
||||
|
||||
Le skill `claude-to-deerflow` vous permet d'interagir avec une instance DeerFlow en cours d'exécution directement depuis [Claude Code](https://docs.anthropic.com/en/docs/claude-code). Envoyez des tâches de recherche, vérifiez le statut, gérez les threads — le tout sans quitter le terminal.
|
||||
|
||||
**Installer le skill** :
|
||||
|
||||
```bash
|
||||
npx skills add https://github.com/bytedance/deer-flow --skill claude-to-deerflow
|
||||
```
|
||||
|
||||
Assurez-vous ensuite que DeerFlow tourne (par défaut sur `http://localhost:2026`) et utilisez la commande `/claude-to-deerflow` dans Claude Code.
|
||||
|
||||
**Ce que vous pouvez faire** :
|
||||
- Envoyer des messages à DeerFlow et recevoir des réponses en streaming
|
||||
- Choisir le mode d'exécution : flash (rapide), standard, pro (planification), ultra (sub-agents)
|
||||
- Vérifier la santé de DeerFlow, lister les modèles/skills/agents
|
||||
- Gérer les threads et l'historique des conversations
|
||||
- Upload des fichiers pour analyse
|
||||
|
||||
**Variables d'environnement** (optionnel, pour des endpoints custom) :
|
||||
|
||||
```bash
|
||||
DEERFLOW_URL=http://localhost:2026 # Unified proxy base URL
|
||||
DEERFLOW_GATEWAY_URL=http://localhost:2026 # Gateway API
|
||||
DEERFLOW_LANGGRAPH_URL=http://localhost:2026/api/langgraph # LangGraph API
|
||||
```
|
||||
|
||||
Voir [`skills/public/claude-to-deerflow/SKILL.md`](skills/public/claude-to-deerflow/SKILL.md) pour la référence API complète.
|
||||
|
||||
### Sub-Agents
|
||||
|
||||
Les tâches complexes tiennent rarement en une seule passe. DeerFlow les décompose.
|
||||
|
||||
L'agent principal peut lancer des sub-agents à la volée — chacun avec son propre contexte délimité, ses outils et ses conditions d'arrêt. Les sub-agents s'exécutent en parallèle quand c'est possible, remontent des résultats structurés, et l'agent principal synthétise le tout en une sortie cohérente.
|
||||
|
||||
C'est comme ça que DeerFlow gère les tâches qui prennent de quelques minutes à plusieurs heures : une tâche de recherche peut se déployer en une dizaine de sub-agents, chacun explorant un angle différent, puis converger vers un seul rapport — ou un site web — ou un jeu de slides avec des visuels générés. Un seul harness, de nombreuses mains.
|
||||
|
||||
### Sandbox et système de fichiers
|
||||
|
||||
DeerFlow ne se contente pas de *parler* de faire les choses. Il dispose de son propre ordinateur.
|
||||
|
||||
Chaque tâche s'exécute dans un conteneur Docker isolé avec un système de fichiers complet — skills, workspace, uploads, outputs. L'agent lit, écrit et édite des fichiers. Il exécute des commandes bash et du code. Il visualise des images. Le tout sandboxé, le tout auditable, zéro contamination entre les sessions.
|
||||
|
||||
C'est la différence entre un chatbot avec accès à des outils et un agent doté d'un véritable environnement d'exécution.
|
||||
|
||||
```
|
||||
# Paths inside the sandbox container
|
||||
/mnt/user-data/
|
||||
├── uploads/ ← your files
|
||||
├── workspace/ ← agents' working directory
|
||||
└── outputs/ ← final deliverables
|
||||
```
|
||||
|
||||
### Context Engineering
|
||||
|
||||
**Contexte isolé des Sub-Agents** : chaque sub-agent s'exécute dans son propre contexte isolé. Il ne peut voir ni le contexte de l'agent principal, ni celui des autres sub-agents. L'objectif est de garantir que chaque sub-agent reste concentré sur sa tâche sans être parasité par des informations non pertinentes.
|
||||
|
||||
**Résumé** : au sein d'une session, DeerFlow gère le contexte de manière agressive — en résumant les sous-tâches terminées, en déchargeant les résultats intermédiaires vers le système de fichiers, en compressant ce qui n'est plus immédiatement pertinent. Ça lui permet de rester efficace sur des tâches longues et multi-étapes sans faire exploser la fenêtre de contexte.
|
||||
|
||||
### Mémoire à long terme
|
||||
|
||||
La plupart des agents oublient tout dès qu'une conversation se termine. DeerFlow, lui, se souvient.
|
||||
|
||||
D'une session à l'autre, DeerFlow construit une mémoire persistante de votre profil, de vos préférences et de vos connaissances accumulées. Plus vous l'utilisez, mieux il vous connaît — votre style d'écriture, votre stack technique, vos workflows récurrents. La mémoire est stockée localement et reste sous votre contrôle.
|
||||
|
||||
Les mises à jour de la mémoire ignorent désormais les entrées de faits en double au moment de l'application, de sorte que les préférences et le contexte répétés ne s'accumulent plus indéfiniment entre les sessions.
|
||||
|
||||
## Modèles recommandés
|
||||
|
||||
DeerFlow est agnostique en termes de modèle — il fonctionne avec n'importe quel LLM implémentant l'API compatible OpenAI. Cela dit, il offre de meilleures performances avec des modèles qui supportent :
|
||||
|
||||
- **De longues fenêtres de contexte** (100k+ tokens) pour la recherche approfondie et les tâches multi-étapes
|
||||
- **Des capacités de raisonnement** pour la planification adaptative et la décomposition de tâches complexes
|
||||
- **Des entrées multimodales** pour la compréhension d'images et de vidéos
|
||||
- **Un usage fiable des outils (tool use)** pour des appels de fonctions et des sorties structurées fiables
|
||||
|
||||
## Client Python intégré
|
||||
|
||||
DeerFlow peut être utilisé comme bibliothèque Python intégrée sans lancer l'ensemble des services HTTP. Le `DeerFlowClient` fournit un accès direct in-process à toutes les capacités d'agent et de Gateway, en retournant les mêmes schémas de réponse que l'API HTTP Gateway. Le HTTP Gateway expose également `DELETE /api/threads/{thread_id}` pour supprimer les données de thread locales gérées par DeerFlow après la suppression du thread LangGraph :
|
||||
|
||||
```python
|
||||
from deerflow.client import DeerFlowClient
|
||||
|
||||
client = DeerFlowClient()
|
||||
|
||||
# Chat
|
||||
response = client.chat("Analyze this paper for me", thread_id="my-thread")
|
||||
|
||||
# Streaming (LangGraph SSE protocol: values, messages-tuple, end)
|
||||
for event in client.stream("hello"):
|
||||
if event.type == "messages-tuple" and event.data.get("type") == "ai":
|
||||
print(event.data["content"])
|
||||
|
||||
# Configuration & management — returns Gateway-aligned dicts
|
||||
models = client.list_models() # {"models": [...]}
|
||||
skills = client.list_skills() # {"skills": [...]}
|
||||
client.update_skill("web-search", enabled=True)
|
||||
client.upload_files("thread-1", ["./report.pdf"]) # {"success": True, "files": [...]}
|
||||
```
|
||||
|
||||
Toutes les méthodes retournant des dicts sont validées en CI contre les modèles de réponse Pydantic du Gateway (`TestGatewayConformance`), garantissant que le client intégré reste synchronisé avec les schémas de l'API HTTP. Voir `backend/packages/harness/deerflow/client.py` pour la documentation API complète.

## ⚠️ Avertissement de sécurité
|
||||
|
||||
### Un déploiement inapproprié peut introduire des risques de sécurité
|
||||
|
||||
DeerFlow dispose de capacités clés à hauts privilèges, notamment **l'exécution de commandes système, les opérations sur les ressources et l'invocation de logique métier**. Il est conçu par défaut pour être **déployé dans un environnement local de confiance (accessible uniquement via l'interface de loopback 127.0.0.1)**. Si vous déployez l'agent dans des environnements non fiables — tels que des réseaux LAN, des serveurs cloud publics ou d'autres environnements accessibles depuis plusieurs terminaux — sans mesures de sécurité strictes, cela peut introduire des risques, notamment :
|
||||
|
||||
- **Invocation non autorisée** : les fonctionnalités de l'agent pourraient être découvertes par des tiers non autorisés ou des scanners malveillants, déclenchant des requêtes non autorisées en masse qui exécutent des opérations à haut risque (commandes système, lecture/écriture de fichiers), pouvant causer de graves conséquences.
|
||||
- **Risques juridiques et de conformité** : si l'agent est utilisé illégalement pour mener des cyberattaques, du vol de données ou d'autres activités illicites, cela peut entraîner des responsabilités juridiques et des risques de conformité.
|
||||
|
||||
### Recommandations de sécurité
|
||||
|
||||
**Note : nous recommandons fortement de déployer DeerFlow dans un environnement réseau local de confiance.** Si vous avez besoin d'un déploiement multi-appareils ou multi-réseaux, vous devez mettre en place des mesures de sécurité strictes, par exemple :
|
||||
|
||||
- **Liste blanche d'IP** : utilisez `iptables`, ou déployez des pare-feux matériels / commutateurs avec ACL, pour **configurer des règles de liste blanche d'IP** et refuser l'accès à toutes les autres adresses IP.
|
||||
- **Passerelle d'authentification** : configurez un proxy inverse (ex. nginx) et **activez une authentification forte en amont**, bloquant tout accès non authentifié.
|
||||
- **Isolation réseau** : si possible, placez l'agent et les appareils de confiance dans le **même VLAN dédié**, isolé des autres équipements réseau.
|
||||
- **Restez informé** : continuez à suivre les mises à jour de sécurité du projet DeerFlow.

## Coding Agent に一文でセットアップを依頼
|
||||
|
||||
Claude Code、Codex、Cursor、Windsurf などの coding agent を使っているなら、次の一文をそのまま渡せます。
|
||||
|
||||
```text
|
||||
DeerFlow がまだ clone されていなければ先に clone してから、https://raw.githubusercontent.com/bytedance/deer-flow/main/Install.md に従ってローカル開発環境を初期化してください
|
||||
```
|
||||
|
||||
このプロンプトは coding agent 向けです。必要なら先にリポジトリを clone し、Docker が使える場合は Docker を優先して初期セットアップを行い、最後に次の起動コマンドと不足している設定項目だけを返します。
|
||||
|
||||
## クイックスタート
|
||||
|
||||
### 設定
|
||||
|
||||
1. **DeerFlowリポジトリをクローン**
|
||||
|
||||
```bash
|
||||
git clone https://github.com/bytedance/deer-flow.git
|
||||
cd deer-flow
|
||||
```
|
||||
|
||||
2. **ローカル設定ファイルの生成**
|
||||
|
||||
プロジェクトルートディレクトリ（`deer-flow/`）から以下を実行します：
|
||||
|
||||
```bash
|
||||
make config
|
||||
```
|
||||
|
||||
このコマンドは、提供されたテンプレートに基づいてローカル設定ファイルを作成します。
|
||||
|
||||
3. **使用するモデルの設定**
|
||||
|
||||
`config.yaml`を編集し、少なくとも1つのモデルを定義します：
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-4 # 内部識別子
|
||||
display_name: GPT-4 # 表示名
|
||||
use: langchain_openai:ChatOpenAI # LangChainクラスパス
|
||||
model: gpt-4 # API用モデル識別子
|
||||
api_key: $OPENAI_API_KEY # APIキー（推奨：環境変数を使用）
|
||||
max_tokens: 4096 # リクエストあたりの最大トークン数
|
||||
temperature: 0.7 # サンプリング温度
|
||||
|
||||
- name: openrouter-gemini-2.5-flash
|
||||
display_name: Gemini 2.5 Flash (OpenRouter)
|
||||
use: langchain_openai:ChatOpenAI
|
||||
model: google/gemini-2.5-flash-preview
|
||||
api_key: $OPENAI_API_KEY # OpenRouterもここではOpenAI互換のフィールド名を使用
|
||||
base_url: https://openrouter.ai/api/v1
|
||||
```
|
||||
|
||||
OpenRouterやOpenAI互換のゲートウェイは、`langchain_openai:ChatOpenAI`と`base_url`で設定します。プロバイダー固有の環境変数名を使用したい場合は、`api_key`でその変数を明示的に指定してください（例：`api_key: $OPENROUTER_API_KEY`）。
|
||||
|
||||
4. **設定したモデルのAPIキーを設定**
|
||||
|
||||
以下のいずれかの方法を選択してください：
|
||||
|
||||
- オプションA：プロジェクトルートの`.env`ファイルを編集（推奨）
|
||||
|
||||
```bash
|
||||
TAVILY_API_KEY=your-tavily-api-key
|
||||
OPENAI_API_KEY=your-openai-api-key
|
||||
# OpenRouterもlangchain_openai:ChatOpenAI + base_url使用時はOPENAI_API_KEYを使用します。
|
||||
# 必要に応じて他のプロバイダーキーを追加
|
||||
INFOQUEST_API_KEY=your-infoquest-api-key
|
||||
```
|
||||
|
||||
- オプションB：シェルで環境変数をエクスポート
|
||||
|
||||
```bash
|
||||
export OPENAI_API_KEY=your-openai-api-key
|
||||
```
|
||||
|
||||
- オプションC：`config.yaml`を直接編集（本番環境には非推奨）
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-4
|
||||
api_key: your-actual-api-key-here # プレースホルダーを置換
|
||||
```
|
||||
|
||||
### アプリケーションの実行
|
||||
|
||||
#### オプション1: Docker（推奨）
|
||||
|
||||
**開発環境**（ホットリロード、ソースマウント）：
|
||||
|
||||
```bash
|
||||
make docker-init # サンドボックスイメージをプル（初回またはイメージ更新時のみ）
|
||||
make docker-start # サービスを開始（config.yamlからサンドボックスモードを自動検出）
|
||||
```
|
||||
|
||||
`make docker-start`は、`config.yaml`がプロビジョナーモード（`sandbox.use: deerflow.community.aio_sandbox:AioSandboxProvider`と`provisioner_url`）を使用している場合にのみ`provisioner`を起動します。
|
||||
|
||||
**本番環境**（ローカルでイメージをビルドし、ランタイム設定とデータをマウント）：
|
||||
|
||||
```bash
|
||||
make up # イメージをビルドして全本番サービスを開始
|
||||
make down # コンテナを停止して削除
|
||||
```
|
||||
|
||||
> [!NOTE]
|
||||
> LangGraphエージェントサーバーは現在`langgraph dev`（オープンソースCLIサーバー）経由で実行されます。
|
||||
|
||||
アクセス: http://localhost:2026
|
||||
|
||||
詳細なDocker開発ガイドは[CONTRIBUTING.md](CONTRIBUTING.md)をご覧ください。
|
||||
|
||||
#### オプション2: ローカル開発
|
||||
|
||||
サービスをローカルで実行する場合：
|
||||
|
||||
前提条件：上記の「設定」手順を先に完了してください（`make config`とモデルAPIキー）。`make dev`には有効な設定ファイルが必要です（デフォルトはプロジェクトルートの`config.yaml`。`DEER_FLOW_CONFIG_PATH`で上書き可能）。
|
||||
|
||||
1. **前提条件の確認**：
|
||||
```bash
|
||||
make check # Node.js 22+、pnpm、uv、nginxを検証
|
||||
```
|
||||
|
||||
2. **依存関係のインストール**：
|
||||
```bash
|
||||
make install # バックエンド＋フロントエンドの依存関係をインストール
|
||||
```
|
||||
|
||||
3. **（オプション）サンドボックスイメージの事前プル**：
|
||||
```bash
|
||||
# Docker/コンテナベースのサンドボックス使用時に推奨
|
||||
make setup-sandbox
|
||||
```
|
||||
|
||||
4. **サービスの開始**：
|
||||
```bash
|
||||
make dev
|
||||
```
|
||||
|
||||
5. **アクセス**: http://localhost:2026
|
||||
|
||||
### 詳細設定
|
||||
#### サンドボックスモード
|
||||
|
||||
DeerFlowは複数のサンドボックス実行モードをサポートしています：
|
||||
- **ローカル実行**（ホストマシン上で直接サンドボックスコードを実行）
|
||||
- **Docker実行**（分離されたDockerコンテナ内でサンドボックスコードを実行）
|
||||
- **KubernetesによるDocker実行**（プロビジョナーサービス経由でKubernetesポッドでサンドボックスコードを実行）
|
||||
|
||||
Docker開発では、サービスの起動は`config.yaml`のサンドボックスモードに従います。ローカル/Dockerモードでは`provisioner`は起動されません。
|
||||
|
||||
お好みのモードの設定については[サンドボックス設定ガイド](backend/docs/CONFIGURATION.md#sandbox)をご覧ください。
|
||||
|
||||
#### MCPサーバー
|
||||
|
||||
DeerFlowは、機能を拡張するための設定可能なMCPサーバーとスキルをサポートしています。
|
||||
HTTP/SSE MCPサーバーでは、OAuthトークンフロー（`client_credentials`、`refresh_token`）がサポートされています。
|
||||
詳細な手順は[MCPサーバーガイド](backend/docs/MCP_SERVER.md)をご覧ください。
|
||||
|
||||
#### IMチャネル
|
||||
|
||||
DeerFlowはメッセージングアプリからのタスク受信をサポートしています。チャネルは設定時に自動的に開始されます。いずれもパブリックIPは不要です。
|
||||
|
||||
| チャネル | トランスポート | 難易度 |
|
||||
|---------|-----------|------------|
|
||||
| Telegram | Bot API（ロングポーリング） | 簡単 |
|

|
||||
```
|
||||
|
||||
対応するAPIキーを`.env`ファイルに設定します：
|
||||
|
||||
```bash
|
||||
# Telegram
|
||||
TELEGRAM_BOT_TOKEN=123456789:ABCdefGHIjklMNOpqrSTUvwxYZ
|
||||
|
||||
# Slack
|
||||
SLACK_BOT_TOKEN=xoxb-...
|
||||
SLACK_APP_TOKEN=xapp-...
|
||||
|
||||
# Feishu / Lark
|
||||
FEISHU_APP_ID=cli_xxxx
|
||||
FEISHU_APP_SECRET=your_app_secret
|
||||
```
|
||||
|
||||
**Telegramのセットアップ**
|
||||
|
||||
1. [@BotFather](https://t.me/BotFather)とチャットし、`/newbot`を送信してHTTP APIトークンをコピーします。
|
||||
2. `.env`に`TELEGRAM_BOT_TOKEN`を設定し、`config.yaml`でチャネルを有効にします。
|
||||
|
||||
**Slackのセットアップ**
|
||||
|
||||
1. [api.slack.com/apps](https://api.slack.com/apps)でSlackアプリを作成 → 新規アプリ作成 → 最初から作成。
|
||||
2. **OAuth & Permissions**で、Botトークンスコープを追加：`app_mentions:read`、`chat:write`、`im:history`、`im:read`、`im:write`、`files:write`。
|
||||
3. **Socket Mode**を有効化 → `connections:write`スコープのApp-Levelトークン（`xapp-…`）を生成。
|
||||
4. **Event Subscriptions**で、ボットイベントを購読：`app_mention`、`message.im`。
|
||||
5. `.env`に`SLACK_BOT_TOKEN`と`SLACK_APP_TOKEN`を設定し、`config.yaml`でチャネルを有効にします。
|
||||
|
||||
**Feishu / Larkのセットアップ**
|
||||
|
||||
1. [Feishu Open Platform](https://open.feishu.cn/)でアプリを作成 → **ボット**機能を有効化。
|
||||
2. 権限を追加：`im:message`、`im:message.p2p_msg:readonly`、`im:resource`。
|
||||
3. **イベント**で`im.message.receive_v1`を購読し、**ロングコネクション**モードを選択。
|
||||
4. App IDとApp Secretをコピー。`.env`に`FEISHU_APP_ID`と`FEISHU_APP_SECRET`を設定し、`config.yaml`でチャネルを有効にします。
|
||||
|
||||
**コマンド**
|
||||
|
||||
チャネル接続後、チャットから直接DeerFlowと対話できます：
|
||||
|
||||
| コマンド | 説明 |
|
||||
|---------|-------------|
|
||||
| `/new` | 新しい会話を開始 |
|
||||
| `/status` | 現在のスレッド情報を表示 |
|
||||
| `/models` | 利用可能なモデルを一覧表示 |
|
||||
| `/memory` | メモリを表示 |
|
||||
| `/help` | ヘルプを表示 |
|
||||
|
||||
> コマンドプレフィックスのないメッセージは通常のチャットとして扱われ、DeerFlowがスレッドを作成して会話形式で応答します。
|
||||
|
||||
#### LangSmithトレーシング
|
||||
|
||||
DeerFlowには[LangSmith](https://smith.langchain.com)による可観測性が組み込まれています。有効にすると、すべてのLLM呼び出し、エージェント実行、ツール実行がトレースされ、LangSmithダッシュボードで確認できます。
|
||||
|
||||
`.env`ファイルに以下を追加します：
|
||||
|
||||
```bash
|
||||
LANGSMITH_TRACING=true
|
||||
LANGSMITH_ENDPOINT=https://api.smith.langchain.com
|
||||
LANGSMITH_API_KEY=lsv2_pt_xxxxxxxxxxxxxxxx
|
||||
LANGSMITH_PROJECT=xxx
|
||||
```
|
||||
|
||||
Dockerデプロイでは、トレーシングはデフォルトで無効です。`.env`で`LANGSMITH_TRACING=true`と`LANGSMITH_API_KEY`を設定して有効にします。
|
||||
|
||||
## Deep Researchからスーパーエージェントハーネスへ
|
||||
|
||||
DeerFlowはDeep Researchフレームワークとして始まり、コミュニティがそれを大きく発展させました。リリース以来、開発者たちはリサーチを超えて活用してきました：データパイプラインの構築、スライドデッキの生成、ダッシュボードの立ち上げ、コンテンツワークフローの自動化。私たちが予想もしなかったことです。
|
||||
|
||||
これは重要なことを示していました：DeerFlowは単なるリサーチツールではなかったのです。それは**ハーネス**——エージェントが実際に仕事をこなすためのインフラを提供するランタイムでした。
|
||||
|
||||
そこで、ゼロから再構築しました。
|
||||
|
||||
DeerFlow 2.0は、もはやつなぎ合わせるフレームワークではありません。バッテリー同梱、完全に拡張可能なスーパーエージェントハーネスです。LangGraphとLangChainの上に構築され、エージェントが必要とするすべてを標準搭載しています：ファイルシステム、メモリ、スキル、サンドボックス実行、そして複雑なマルチステップタスクのためのプランニングとサブエージェントの生成機能。
|
||||
|
||||
そのまま使うもよし。分解して自分のものにするもよし。
|
||||
|
||||
## コア機能
|
||||
|
||||
### スキルとツール
|
||||
|
||||
スキルこそが、DeerFlowを*ほぼ何でもできる*ものにしています。
|
||||
|
||||
標準的なエージェントスキルは構造化された機能モジュールです——ワークフロー、ベストプラクティス、サポートリソースへの参照を定義するMarkdownファイルです。DeerFlowにはリサーチ、レポート生成、スライド作成、Webページ、画像・動画生成などの組み込みスキルが付属しています。しかし、真の力は拡張性にあります：独自のスキルを追加し、組み込みスキルを置き換え、複合ワークフローに組み合わせることができます。
|
||||
|
||||
スキルはプログレッシブに読み込まれます——タスクが必要とする時にのみ、一度にすべてではありません。これによりコンテキストウィンドウを軽量に保ち、トークンに敏感なモデルでもDeerFlowがうまく動作します。
|
||||
|
||||
Gateway経由で`.skill`アーカイブをインストールする際、DeerFlowは`version`、`author`、`compatibility`などの標準的なオプショナルフロントマターメタデータを受け入れ、有効な外部スキルを拒否しません。
|
||||
|
||||
ツールも同じ哲学に従います。DeerFlowにはコアツールセット——Web検索、Webフェッチ、ファイル操作、bash実行——が付属し、MCPサーバーやPython関数によるカスタムツールをサポートしています。何でも入れ替え可能、何でも追加可能です。
|
||||
|
||||
Gatewayが生成するフォローアップ提案は、プレーン文字列のモデル出力とブロック/リスト形式のリッチコンテンツの両方をJSON配列レスポンスの解析前に正規化するため、プロバイダー固有のコンテンツラッパーが提案をサイレントにドロップすることはありません。

|
||||
#### Claude Code連携
|
||||
|
||||
`claude-to-deerflow`スキルを使えば、[Claude Code](https://docs.anthropic.com/en/docs/claude-code)から直接、実行中のDeerFlowインスタンスと対話できます。リサーチタスクの送信、ステータスの確認、スレッドの管理——すべてターミナルから離れずに実行できます。
|
||||
|
||||
**スキルのインストール**：
|
||||
|
||||
```bash
|
||||
npx skills add https://github.com/bytedance/deer-flow --skill claude-to-deerflow
|
||||
```
|
||||
|
||||
DeerFlowが実行中であることを確認し（デフォルトは`http://localhost:2026`）、Claude Codeで`/claude-to-deerflow`コマンドを使用します。
|
||||
|
||||
**できること**：
|
||||
- DeerFlowにメッセージを送信してストリーミングレスポンスを取得
|
||||
- 実行モードの選択：flash（高速）、standard、pro（プランニング）、ultra（サブエージェント）
|
||||
- DeerFlowのヘルスチェック、モデル/スキル/エージェントの一覧表示
|
||||
- スレッドと会話履歴の管理
|
||||
- 分析用ファイルのアップロード
|
||||
|
||||
**環境変数**（オプション、カスタムエンドポイント用）：
|
||||
|
||||
```bash
|
||||
DEERFLOW_URL=http://localhost:2026 # 統合プロキシベースURL
|
||||
DEERFLOW_GATEWAY_URL=http://localhost:2026 # Gateway API
|
||||
DEERFLOW_LANGGRAPH_URL=http://localhost:2026/api/langgraph # LangGraph API
|
||||
```
|
||||
|
||||
完全なAPIリファレンスは[`skills/public/claude-to-deerflow/SKILL.md`](skills/public/claude-to-deerflow/SKILL.md)をご覧ください。
|
||||
|
||||
### サブエージェント
|
||||
|
||||
複雑なタスクは単一のパスに収まりません。DeerFlowはそれを分解します。
|
||||
|
||||
リードエージェントはオンザフライでサブエージェントを生成できます——それぞれ独自のスコープ付きコンテキスト、ツール、終了条件を持ちます。サブエージェントは可能な限り並列で実行され、構造化された結果を報告し、リードエージェントがすべてを一貫した出力に統合します。
|
||||
|
||||
これがDeerFlowが数分から数時間かかるタスクを処理する方法です：リサーチタスクが十数のサブエージェントに展開され、それぞれが異なる角度を探索し、1つのレポート——またはWebサイト——または生成されたビジュアル付きのスライドデッキに収束します。1つのハーネス、多くの手。
|
||||
|
||||
### サンドボックスとファイルシステム
|
||||
|
||||
DeerFlowは物事を*語る*だけではありません。自分のコンピューターを持っています。
|
||||
|
||||
各タスクは、完全なファイルシステムを持つ分離されたDockerコンテナ内で実行されます——スキル、ワークスペース、アップロード、出力。エージェントはファイルの読み書き・編集を行います。bashコマンドを実行し、コーディングを行います。画像を表示します。すべてサンドボックス化され、すべて監査可能で、セッション間の汚染はゼロです。
|
||||
|
||||
これが、ツールアクセスのあるチャットボットと、実際の実行環境を持つエージェントの違いです。
|
||||
|
||||
```
|
||||
# サンドボックスコンテナ内のパス
|
||||
/mnt/user-data/
|
||||
├── uploads/ ← あなたのファイル
|
||||
├── workspace/ ← エージェントの作業ディレクトリ
|
||||
└── outputs/ ← 最終成果物
|
||||
```
|
||||
|
||||
### コンテキストエンジニアリング
|
||||
|
||||
**分離されたサブエージェントコンテキスト**：各サブエージェントは独自の分離されたコンテキストで実行されます。これにより、サブエージェントはメインエージェントや他のサブエージェントのコンテキストを見ることができません。これは、サブエージェントが目の前のタスクに集中し、メインエージェントや他のサブエージェントのコンテキストに気を取られないようにするために重要です。
|
||||
|
||||
**要約化**：セッション内で、DeerFlowはコンテキストを積極的に管理します——完了したサブタスクの要約、中間結果のファイルシステムへのオフロード、もはや直接関係のないものの圧縮。これにより、コンテキストウィンドウを超えることなく、長いマルチステップタスク全体を通じてシャープさを維持します。
|
||||
|
||||
### 長期メモリ
|
||||
|
||||
ほとんどのエージェントは、会話が終わるとすべてを忘れます。DeerFlowは記憶します。
|
||||
|
||||
セッションをまたいで、DeerFlowはあなたのプロフィール、好み、蓄積された知識の永続的なメモリを構築します。使えば使うほど、あなたのことをよく知るようになります——あなたの文体、技術スタック、繰り返されるワークフロー。メモリはローカルに保存され、あなたの管理下にあります。
|
||||
|
||||
メモリ更新は適用時に重複するファクトエントリをスキップするようになり、繰り返される好みやコンテキストがセッションをまたいで際限なく蓄積されることはありません。
|
||||
|
||||
## 推奨モデル
|
||||
|
||||
DeerFlowはモデルに依存しません——OpenAI互換APIを実装する任意のLLMで動作します。とはいえ、以下をサポートするモデルで最高のパフォーマンスを発揮します：
|
||||
|
||||
- **長いコンテキストウィンドウ**（10万トークン以上）：深いリサーチとマルチステップタスク向け
|
||||
- **推論能力**：適応的なプランニングと複雑な分解向け
|
||||
- **マルチモーダル入力**：画像理解と動画理解向け
|
||||
- **強力なツール使用**：信頼性の高いファンクションコーリングと構造化された出力向け
|
||||
|
||||
## 組み込みPythonクライアント
|
||||
|
||||
DeerFlowは、完全なHTTPサービスを実行せずに組み込みPythonライブラリとして使用できます。`DeerFlowClient`は、すべてのエージェントとGateway機能へのプロセス内直接アクセスを提供し、HTTP Gateway APIと同じレスポンススキーマを返します：
|
||||
|
||||
```python
|
||||
from deerflow.client import DeerFlowClient
|
||||
|
||||
client = DeerFlowClient()
|
||||
|
||||
# チャット
|
||||
response = client.chat("Analyze this paper for me", thread_id="my-thread")
|
||||
|
||||

## ⚠️ セキュリティに関する注意
|
||||
|
||||
### 不適切なデプロイはセキュリティリスクを引き起こす可能性があります
|
||||
|
||||
DeerFlowは**システムコマンドの実行、リソース操作、ビジネスロジックの呼び出し**などの重要な高権限機能を備えており、デフォルトでは**ローカルの信頼できる環境（127.0.0.1のループバックアクセスのみ）にデプロイされる設計**になっています。信頼できないLAN、公開クラウドサーバー、または複数のエンドポイントからアクセス可能なネットワーク環境にエージェントをデプロイし、厳格なセキュリティ対策を講じない場合、以下のようなセキュリティリスクが生じる可能性があります：
|
||||
|
||||
- **不正な違法呼び出し**：エージェントの機能が権限のない第三者や悪意のあるインターネットスキャナーに発見され、システムコマンドやファイル読み書きなどの高リスク操作を実行する不正な一括リクエストが引き起こされ、重大なセキュリティ上の問題が発生する可能性があります。
|
||||
- **コンプライアンスおよび法的リスク**：エージェントがサイバー攻撃やデータ窃取などの違法行為に不正使用された場合、法的責任やコンプライアンス上のリスクが生じる可能性があります。
|
||||
|
||||
### セキュリティ推奨事項
|
||||
|
||||
**注意：DeerFlowはローカルの信頼できるネットワーク環境にデプロイすることを強く推奨します。** クロスデバイス・クロスネットワークのデプロイが必要な場合は、以下のような厳格なセキュリティ対策を実装する必要があります：
|
||||
|
||||
- **IPホワイトリストの設定**：`iptables`を使用するか、ハードウェアファイアウォール / ACL機能付きスイッチをデプロイして**IPホワイトリストルールを設定**し、他のすべてのIPアドレスからのアクセスを拒否します。
|
||||
- **前置認証**：リバースプロキシ（nginxなど）を設定し、**強力な前置認証を有効化**して、認証なしのアクセスをブロックします。
|
||||
- **ネットワーク分離**：可能であれば、エージェントと信頼できるデバイスを**同一の専用VLAN**に配置し、他のネットワークデバイスから隔離します。
|
||||
- **アップデートを継続的に確認**：DeerFlowのセキュリティ機能のアップデートを継続的にフォローしてください。

## Установка одной фразой для coding agent
|
||||
|
||||
Если вы используете Claude Code, Codex, Cursor, Windsurf или другой coding agent, просто отправьте ему эту фразу:
|
||||
|
||||
```text
|
||||
Если DeerFlow еще не клонирован, сначала клонируй его, а затем подготовь локальное окружение разработки по инструкции https://raw.githubusercontent.com/bytedance/deer-flow/main/Install.md
|
||||
```
|
||||
|
||||
Этот prompt предназначен для coding agent. Он просит агента при необходимости сначала клонировать репозиторий, предпочесть Docker, если он доступен, и в конце вернуть точную команду запуска и список недостающих настроек.
|
||||
|
||||
## Быстрый старт
|
||||
|
||||
### Конфигурация
|
||||
|
||||
1. **Склонировать репозиторий DeerFlow**
|
||||
|
||||
```bash
|
||||
git clone https://github.com/bytedance/deer-flow.git
|
||||
cd deer-flow
|
||||
```
|
||||
|
||||
2. **Сгенерировать локальные конфиги**
|
||||
|
||||
Из корня проекта (`deer-flow/`) запустите:
|
||||
|
||||
```bash
|
||||
make config
|
||||
```
|
||||
|
||||
Команда создаёт локальные конфиги на основе шаблонов.
|
||||
|
||||
3. **Настроить модель**
|
||||
|
||||
Отредактируйте `config.yaml` и задайте хотя бы одну модель:
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-4 # Внутренний идентификатор
|
||||
display_name: GPT-4 # Отображаемое имя
|
||||
use: langchain_openai:ChatOpenAI # Путь к классу LangChain
|
||||
model: gpt-4 # Идентификатор модели для API
|
||||
api_key: $OPENAI_API_KEY # API-ключ (рекомендуется: переменная окружения)
|
||||
max_tokens: 4096 # Максимальное количество токенов на запрос
|
||||
temperature: 0.7 # Температура сэмплирования
|
||||
|
||||
- name: openrouter-gemini-2.5-flash
|
||||
display_name: Gemini 2.5 Flash (OpenRouter)
|
||||
use: langchain_openai:ChatOpenAI
|
||||
model: google/gemini-2.5-flash-preview
|
||||
api_key: $OPENAI_API_KEY
|
||||
base_url: https://openrouter.ai/api/v1
|
||||
|
||||
- name: gpt-5-responses
|
||||
display_name: GPT-5 (Responses API)
|
||||
use: langchain_openai:ChatOpenAI
|
||||
model: gpt-5
|
||||
api_key: $OPENAI_API_KEY
|
||||
use_responses_api: true
|
||||
output_version: responses/v1
|
||||
```
|
||||
|
||||
OpenRouter и аналогичные OpenAI-совместимые шлюзы настраиваются через `langchain_openai:ChatOpenAI` с параметром `base_url`. Для CLI-провайдеров:
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-5.4
|
||||
display_name: GPT-5.4 (Codex CLI)
|
||||
use: deerflow.models.openai_codex_provider:CodexChatModel
|
||||
model: gpt-5.4
|
||||
supports_thinking: true
|
||||
supports_reasoning_effort: true
|
||||
|
||||
- name: claude-sonnet-4.6
|
||||
display_name: Claude Sonnet 4.6 (Claude Code OAuth)
|
||||
use: deerflow.models.claude_provider:ClaudeChatModel
|
||||
model: claude-sonnet-4-6
|
||||
max_tokens: 4096
|
||||
supports_thinking: true
|
||||
```
|
||||
|
||||
- Codex CLI читает `~/.codex/auth.json`
|
||||
- Claude Code принимает `CLAUDE_CODE_OAUTH_TOKEN`, `ANTHROPIC_AUTH_TOKEN` или `~/.claude/.credentials.json`
|
||||
- На macOS при необходимости экспортируйте аутентификацию Claude Code явно:
|
||||
|
||||
```bash
|
||||
eval "$(python3 scripts/export_claude_code_oauth.py --print-export)"
|
||||
```
|
||||
|
||||
4. **Указать API-ключи**
|
||||
|
||||
- **Вариант А**: файл `.env` в корне проекта (рекомендуется)
|
||||
|
||||
```bash
|
||||
TAVILY_API_KEY=your-tavily-api-key
|
||||
OPENAI_API_KEY=your-openai-api-key
|
||||
INFOQUEST_API_KEY=your-infoquest-api-key
|
||||
```
|
||||
|
||||
- **Вариант Б**: переменные окружения в терминале
|
||||
|
||||
```bash
|
||||
export OPENAI_API_KEY=your-openai-api-key
|
||||
```
|
||||
|
||||
- **Вариант В**: напрямую в `config.yaml` (не рекомендуется для продакшена)
|
||||
|
||||
### Запуск
|
||||
|
||||
#### Вариант 1: Docker (рекомендуется)
|
||||
|
||||
**Разработка** (hot-reload, монтирование исходников):
|
||||
|
||||
```bash
|
||||
make docker-init # Загрузить образ Sandbox (один раз или при обновлении)
|
||||
make docker-start # Запустить сервисы
|
||||
```
|
||||
|
||||
**Продакшен** (собирает образы локально):
|
||||
|
||||
```bash
|
||||
make up # Собрать образы и запустить все сервисы
|
||||
make down # Остановить и удалить контейнеры
|
||||
```
|
||||
|
||||
> [!TIP]
|
||||
> На Linux при ошибке `permission denied` для Docker daemon добавьте пользователя в группу `docker` и перелогиньтесь. Подробнее в [CONTRIBUTING.md](CONTRIBUTING.md#linux-docker-daemon-permission-denied).
|
||||
|
||||
Адрес: http://localhost:2026
|
||||
|
||||
#### Вариант 2: Локальная разработка
|
||||
|
||||
1. **Проверить зависимости**:
|
||||
```bash
|
||||
make check # Проверяет Node.js 22+, pnpm, uv, nginx
|
||||
```
|
||||
|
||||
2. **Установить зависимости**:
|
||||
```bash
|
||||
make install
|
||||
```
|
||||
|
||||
3. **(Опционально) Загрузить образ Sandbox заранее**:
|
||||
```bash
|
||||
make setup-sandbox
|
||||
```
|
||||
|
||||
4. **Запустить сервисы**:
|
||||
```bash
|
||||
make dev
|
||||
```
|
||||
|
||||
5. **Адрес**: http://localhost:2026
|
||||
|
||||
### Дополнительно
|
||||
|
||||
#### Режим Sandbox
|
||||
|
||||
DeerFlow поддерживает несколько режимов выполнения:
|
||||
- **Локальное выполнение** — код запускается прямо на хосте
|
||||
- **Docker** — код выполняется в изолированных Docker-контейнерах
|
||||
- **Docker + Kubernetes** — выполнение в Kubernetes-подах через provisioner
|
||||
|
||||
Подробнее в [руководстве по конфигурации Sandbox](backend/docs/CONFIGURATION.md#sandbox).
|
||||
|
||||
#### MCP-сервер
|
||||
|
||||
DeerFlow поддерживает настраиваемые MCP-серверы для расширения возможностей. Для HTTP/SSE MCP-серверов поддерживаются OAuth-токены (`client_credentials`, `refresh_token`). Подробнее в [руководстве по MCP-серверу](backend/docs/MCP_SERVER.md).
|
||||
|
||||
#### Мессенджеры
|
||||
|
||||
DeerFlow принимает задачи прямо из мессенджеров. Каналы запускаются автоматически при настройке, публичный IP не нужен.
|
||||
|
||||
| Канал | Транспорт | Сложность |
|
||||
|-------|-----------|-----------|
|
||||
| Telegram | Bot API (long-polling) | Просто |
|
||||
| Slack | Socket Mode | Средне |
|
||||
| Feishu / Lark | WebSocket | Средне |
|
||||
|
||||
**Конфигурация в `config.yaml`:**
|
||||
|
||||
```yaml
|
||||
channels:
|
||||
feishu:
|
||||
enabled: true
|
||||
app_id: $FEISHU_APP_ID
|
||||
app_secret: $FEISHU_APP_SECRET
|
||||
# domain: https://open.feishu.cn # China (default)
|
||||
# domain: https://open.larksuite.com # International
|
||||
|
||||
slack:
|
||||
enabled: true
|
||||
bot_token: $SLACK_BOT_TOKEN
|
||||
app_token: $SLACK_APP_TOKEN
|
||||
allowed_users: []
|
||||
|
||||
telegram:
|
||||
enabled: true
|
||||
bot_token: $TELEGRAM_BOT_TOKEN
|
||||
allowed_users: []
|
||||
```
|
||||
|
||||
**Настройка Telegram**
|
||||
|
||||
1. Напишите [@BotFather](https://t.me/BotFather), отправьте `/newbot` и скопируйте HTTP API-токен.
|
||||
2. Укажите `TELEGRAM_BOT_TOKEN` в `.env` и включите канал в `config.yaml`.
|
||||
|
||||
**Доступные команды**
|
||||
|
||||
| Команда | Описание |
|
||||
|---------|----------|
|
||||
| `/new` | Начать новый диалог |
|
||||
| `/status` | Показать информацию о текущем треде |
|
||||
| `/models` | Список доступных моделей |
|
||||
| `/memory` | Просмотреть память |
|
||||
| `/help` | Показать справку |
|
||||
|
||||
> Сообщения без команды воспринимаются как обычный чат — DeerFlow создаёт тред и отвечает.
|
||||
|
||||
#### Трассировка LangSmith
|
||||
|
||||
DeerFlow имеет встроенную интеграцию с [LangSmith](https://smith.langchain.com) для наблюдаемости. При включении все вызовы LLM, запуски агентов и выполнения инструментов отслеживаются и отображаются в дашборде LangSmith.
|
||||
|
||||
Добавьте в файл `.env` в корне проекта:
|
||||
|
||||
```bash
|
||||
LANGSMITH_TRACING=true
|
||||
LANGSMITH_API_KEY=lsv2_pt_xxxxxxxxxxxxxxxx
|
||||
LANGSMITH_PROJECT=deer-flow
|
||||
```
|
||||
|
||||
`LANGSMITH_ENDPOINT` по умолчанию `https://api.smith.langchain.com` и может быть переопределён при необходимости. Устаревшие переменные `LANGCHAIN_*` (`LANGCHAIN_TRACING_V2`, `LANGCHAIN_API_KEY` и т.д.) также поддерживаются для обратной совместимости; `LANGSMITH_*` имеет приоритет, когда заданы обе.
|
||||
|
||||
В Docker-развёртываниях трассировка отключена по умолчанию. Установите `LANGSMITH_TRACING=true` и `LANGSMITH_API_KEY` в `.env` для включения.
|
||||
|
||||
## От Deep Research к Super Agent Harness
|
||||
|
||||
DeerFlow начинался как фреймворк для Deep Research, и сообщество вышло далеко за эти рамки. После запуска разработчики строили пайплайны, генерировали презентации, поднимали дашборды, автоматизировали контент. То, чего мы не ожидали.
|
||||
|
||||
Стало понятно: DeerFlow не просто research-инструмент. Это **harness**: runtime, который даёт агентам необходимую инфраструктуру.
|
||||
|
||||
Поэтому мы переписали всё с нуля.
|
||||
|
||||
DeerFlow 2.0 — это Super Agent Harness «из коробки». Batteries included, полностью расширяемый. Построен на LangGraph и LangChain. По умолчанию есть всё, что нужно агенту: файловая система, memory, skills, sandbox-выполнение и возможность планировать и запускать sub-agents для сложных многошаговых задач.
|
||||
|
||||
Используйте как есть. Или разберите и переделайте под себя.
|
||||
|
||||
## Core Features
|
||||
|
||||
### Skills & Tools
|
||||
|
||||
Skills — это то, что позволяет DeerFlow делать почти что угодно.
|
||||
|

Agent Skill — это структурированный модуль: Markdown-файл с описанием воркфлоу, лучших практик и ссылок на ресурсы. DeerFlow поставляется со встроенными skills для ресёрча, генерации отчётов, слайдов, веб-страниц, изображений и видео. Но главное — расширяемость: добавляйте свои skills, заменяйте встроенные или собирайте из них составные воркфлоу.
|
||||
|
||||
Skills загружаются по мере необходимости, только когда задача их требует. Это держит контекстное окно чистым.

#### Интеграция с Claude Code
|
||||
|
||||
Skill `claude-to-deerflow` позволяет работать с DeerFlow прямо из [Claude Code](https://docs.anthropic.com/en/docs/claude-code). Отправляйте задачи, проверяйте статус, управляйте тредами, не выходя из терминала.
|
||||
|
||||
**Установка скилла**:
|
||||
|
||||
```bash
|
||||
npx skills add https://github.com/bytedance/deer-flow --skill claude-to-deerflow
|
||||
```
|
||||
|
||||
**Что можно делать**:
|
||||
- Отправлять сообщения в DeerFlow и получать потоковые ответы
|
||||
- Выбирать режимы выполнения: flash (быстро), standard, pro (planning), ultra (sub-agents)
|
||||
- Проверять статус DeerFlow, просматривать модели, скиллы, агентов
|
||||
- Управлять тредами и историей диалога
|
||||
- Загружать файлы для анализа
|
||||
|
||||
Полный справочник API в [`skills/public/claude-to-deerflow/SKILL.md`](skills/public/claude-to-deerflow/SKILL.md).
|
||||
|
||||
### Sub-Agents
|
||||
|
||||
Сложные задачи редко решаются за один проход. DeerFlow их декомпозирует.
|
||||
|
||||
Lead agent запускает sub-agents на лету, каждый со своим изолированным контекстом, инструментами и условиями завершения. Sub-agents работают параллельно, возвращают структурированные результаты, а lead agent собирает всё в единый итог.
|
||||
|
||||
Вот как DeerFlow справляется с задачами на минуты и часы: research-задача разветвляется в дюжину sub-agents, каждый копает свой угол, потом всё сходится в один отчёт, или сайт, или слайддек со сгенерированными визуалами. Один harness, много рук.
|
||||
|
||||
### Sandbox & файловая система
|
||||
|
||||
DeerFlow не просто *говорит* о том, что умеет что-то делать. У него есть собственный компьютер.
|
||||
|
||||
Каждая задача выполняется внутри изолированного Docker-контейнера с полной файловой системой: skills, workspace, uploads, outputs. Агент читает, пишет и редактирует файлы. Выполняет bash-команды и пишет код. Смотрит на изображения. Всё изолировано, всё прозрачно, никакого пересечения между сессиями.
|
||||
|
||||
Это разница между чатботом с доступом к инструментам и агентом с реальной средой выполнения.
|
||||
|
||||
```
|
||||
# Пути внутри контейнера sandbox
|
||||
/mnt/user-data/
|
||||
├── uploads/ ← ваши файлы
|
||||
├── workspace/ ← рабочая директория агентов
|
||||
└── outputs/ ← результаты
|
||||
```
|
||||
|
||||
### Context Engineering
|
||||
|
||||
**Изолированный контекст**: каждый sub-agent работает в своём контексте и не видит контекст главного агента или других sub-agents. Агент фокусируется на своей задаче.
|
||||
|
||||
**Управление контекстом**: внутри сессии DeerFlow агрессивно сжимает контекст и суммирует завершённые подзадачи, выгружает промежуточные результаты в файловую систему, сжимает то, что уже не актуально. На длинных многошаговых задачах контекстное окно не переполняется.
|
||||
|
||||
### Long-Term Memory
|
||||
|
||||
Большинство агентов забывают всё, когда диалог заканчивается. DeerFlow помнит.
|
||||
|
||||
DeerFlow сохраняет ваш профиль, предпочтения и накопленные знания между сессиями. Чем больше используете, тем лучше он вас знает: стиль, технологический стек, повторяющиеся воркфлоу. Всё хранится локально и остаётся под вашим контролем.
|
||||
|
||||
## Рекомендуемые модели
|
||||
|
||||
DeerFlow работает с любым LLM через OpenAI-совместимый API. Лучше всего — с моделями, которые поддерживают:
|
||||
|
||||
- **Большое контекстное окно** (100k+ токенов) — для deep research и многошаговых задач
|
||||
- **Reasoning capabilities** — для адаптивного планирования и сложной декомпозиции
|
||||
- **Multimodal inputs** — для работы с изображениями и видео
|
||||
- **Strong tool-use** — для надёжного вызова функций и структурированных ответов
|
||||
|
||||
## Встроенный Python-клиент
|
||||
|
||||
DeerFlow можно использовать как Python-библиотеку прямо в коде — без запуска HTTP-сервисов. `DeerFlowClient` даёт доступ ко всем возможностям агента и Gateway, возвращает те же схемы ответов, что и HTTP Gateway API:
|
||||
|
||||
```python
|
||||
from deerflow.client import DeerFlowClient
|
||||
|
||||
client = DeerFlowClient()
|
||||
|
||||
# Chat
|
||||
response = client.chat("Analyze this paper for me", thread_id="my-thread")
|
||||
|
||||
# Streaming (LangGraph SSE protocol: values, messages-tuple, end)
|
||||
for event in client.stream("hello"):
|
||||
if event.type == "messages-tuple" and event.data.get("type") == "ai":
|
||||
print(event.data["content"])
|
||||
|
||||
# Configuration & management — returns Gateway-aligned dicts
|
||||
models = client.list_models() # {"models": [...]}
|
||||
skills = client.list_skills() # {"skills": [...]}
|
||||
client.update_skill("web-search", enabled=True)
|
||||
client.upload_files("thread-1", ["./report.pdf"]) # {"success": True, "files": [...]}
|
||||
```

## ⚠️ Безопасность
|
||||
|
||||
### Неправильное развёртывание может привести к угрозам безопасности
|
||||
|
||||
DeerFlow обладает ключевыми высокопривилегированными возможностями, включая **выполнение системных команд, операции с ресурсами и вызов бизнес-логики**. По умолчанию он рассчитан на **развёртывание в локальной доверенной среде (доступ только через loopback-адрес 127.0.0.1)**. Если вы разворачиваете агент в недоверенных средах — локальных сетях, публичных облачных серверах или других окружениях, доступных с нескольких устройств — без строгих мер безопасности, это может привести к следующим угрозам:
|
||||
|
||||
- **Несанкционированные вызовы**: функциональность агента может быть обнаружена неавторизованными третьими лицами или вредоносными сканерами, что приведёт к массовым несанкционированным запросам с выполнением высокорисковых операций (системные команды, чтение/запись файлов) и серьёзным последствиям для безопасности.
|
||||
- **Юридические и compliance-риски**: если агент будет незаконно использован для кибератак, кражи данных или других противоправных действий, это может повлечь юридическую ответственность и compliance-риски.
|
||||
|
||||
### Рекомендации по безопасности
|
||||
|
||||
**Примечание: настоятельно рекомендуем развёртывать DeerFlow только в локальной доверенной сети.** Если вам необходимо развёртывание через несколько устройств или сетей, обязательно реализуйте строгие меры безопасности, например:
|
||||
|
||||
- **Белый список IP-адресов**: используйте `iptables` или аппаратные межсетевые экраны / коммутаторы с ACL, чтобы **настроить правила белого списка IP** и заблокировать доступ со всех остальных адресов.
|
||||
- **Шлюз аутентификации**: настройте обратный прокси (nginx и др.) и **включите строгую предварительную аутентификацию**, запрещающую любой доступ без авторизации.
|
||||
- **Сетевая изоляция**: по возможности разместите агент и доверенные устройства в **одном выделенном VLAN**, изолированном от остальной сети.
|
||||
- **Следите за обновлениями**: регулярно отслеживайте обновления безопасности проекта DeerFlow.

## 一句话交给 Coding Agent 安装
|
||||
|
||||
如果你在用 Claude Code、Codex、Cursor、Windsurf 或其他 coding agent，可以直接把下面这句话发给它：
|
||||
|
||||
```text
|
||||
如果还没 clone DeerFlow，就先 clone，然后按照 https://raw.githubusercontent.com/bytedance/deer-flow/main/Install.md 把它的本地开发环境初始化好
|
||||
```
|
||||
|
||||
这条提示词是给 coding agent 用的。它会在需要时先 clone 仓库，优先选择 Docker，完成初始化，并在结束时告诉你下一条启动命令，以及还缺哪些配置需要你补充。
|
||||
|
||||
## 快速开始
|
||||
|
||||
### 配置
|
||||
|
||||
1. **克隆 DeerFlow 仓库**
|
||||
|
||||
```bash
|
||||
git clone https://github.com/bytedance/deer-flow.git
|
||||
cd deer-flow
|
||||
```
|
||||
|
||||
2. **生成本地配置文件**
|
||||
|
||||
在项目根目录（`deer-flow/`）执行：
|
||||
|
||||
```bash
|
||||
make config
|
||||
```
|
||||
|
||||
这个命令会基于示例模板生成本地配置文件。
|
||||
|
||||
3. **配置你要使用的模型**
|
||||
|
||||
编辑 `config.yaml`，至少定义一个模型：
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-4 # 内部标识
|
||||
display_name: GPT-4 # 展示名称
|
||||
use: langchain_openai:ChatOpenAI # LangChain 类路径
|
||||
model: gpt-4 # API 使用的模型标识
|
||||
api_key: $OPENAI_API_KEY # API key（推荐使用环境变量）
|
||||
max_tokens: 4096 # 单次请求最大 tokens
|
||||
temperature: 0.7 # 采样温度
|
||||
|
||||
- name: openrouter-gemini-2.5-flash
|
||||
display_name: Gemini 2.5 Flash (OpenRouter)
|
||||
use: langchain_openai:ChatOpenAI
|
||||
model: google/gemini-2.5-flash-preview
|
||||
api_key: $OPENAI_API_KEY # 这里 OpenRouter 依然沿用 OpenAI 兼容字段名
|
||||
base_url: https://openrouter.ai/api/v1
|
||||
```
|
||||
|
||||
OpenRouter 以及类似的 OpenAI 兼容网关，建议通过 `langchain_openai:ChatOpenAI` 配合 `base_url` 来配置。如果你更想用 provider 自己的环境变量名，也可以直接把 `api_key` 指向对应变量，例如 `api_key: $OPENROUTER_API_KEY`。
|
||||
|
||||
4. **为已配置的模型设置 API key**
|
||||
|
||||
可任选以下一种方式：
|
||||
|
||||
- 方式 A：编辑项目根目录下的 `.env` 文件（推荐）
|
||||
|
||||
```bash
|
||||
TAVILY_API_KEY=your-tavily-api-key
|
||||
OPENAI_API_KEY=your-openai-api-key
|
||||
# 如果配置使用的是 langchain_openai:ChatOpenAI + base_url，OpenRouter 也会读取 OPENAI_API_KEY
|
||||
# 其他 provider 的 key 按需补充
|
||||
INFOQUEST_API_KEY=your-infoquest-api-key
|
||||
```
|
||||
|
||||
- 方式 B：在 shell 中导出环境变量
|
||||
|
||||
```bash
|
||||
export OPENAI_API_KEY=your-openai-api-key
|
||||
```
|
||||
|
||||
- 方式 C：直接编辑 `config.yaml`（不建议用于生产环境）
|
||||
|
||||
```yaml
|
||||
models:
|
||||
- name: gpt-4
|
||||
api_key: your-actual-api-key-here # 替换为真实 key
|
||||
```
|
||||
|
||||
### 运行应用
|
||||
|
||||
#### 部署建议与资源规划
|
||||
|
||||
可以先按下面的资源档位来选择 DeerFlow 的运行方式：
|
||||
|
||||
| 部署场景 | 起步配置 | 推荐配置 | 说明 |
|
||||
|---------|-----------|------------|-------|
|
||||
| 本地体验 / `make dev` | 4 vCPU、8 GB 内存、20 GB SSD 可用空间 | 8 vCPU、16 GB 内存 | 适合单个开发者或单个轻量会话，且模型走外部 API。`2 核 / 4 GB` 通常跑不稳。 |
|
||||
| Docker 开发 / `make docker-start` | 4 vCPU、8 GB 内存、25 GB SSD 可用空间 | 8 vCPU、16 GB 内存 | 镜像构建、源码挂载和 sandbox 容器都会比纯本地模式更吃资源。 |
|
||||
| 长期运行服务 / `make up` | 8 vCPU、16 GB 内存、40 GB SSD 可用空间 | 16 vCPU、32 GB 内存 | 更适合共享环境、多 agent 任务、报告生成或更重的 sandbox 负载。 |
|
||||
|
||||
- 上面的配置只覆盖 DeerFlow 本身；如果你还要本机部署本地大模型，请单独为模型服务预留资源。
|
||||
- 持续运行的服务更推荐使用 Linux + Docker。macOS 和 Windows 更适合作为开发机或体验环境。
|
||||
- 如果 CPU 或内存长期打满，先降低并发会话或重任务数量，再考虑升级到更高一档配置。
|
||||
|
||||
#### 方式一：Docker（推荐）
|
||||
|
||||
**开发模式**（支持热更新，挂载源码）：
|
||||
|
||||
```bash
|
||||
make docker-init # 拉取 sandbox 镜像（首次运行或镜像更新时执行）
|
||||
make docker-start # 启动服务（会根据 config.yaml 自动判断 sandbox 模式）
|
||||
```
|
||||
|
||||
如果 `config.yaml` 使用的是 provisioner 模式（`sandbox.use: deerflow.community.aio_sandbox:AioSandboxProvider` 且配置了 `provisioner_url`），`make docker-start` 才会启动 `provisioner`。
|
||||
|
||||
**生产模式**（本地构建镜像，并挂载运行期配置与数据）：
|
||||
|
||||
```bash
|
||||
make up # 构建镜像并启动全部生产服务
|
||||
make down # 停止并移除容器
|
||||
```
|
||||
|
||||
> [!NOTE]
|
||||
> 当前 LangGraph agent server 通过开源 CLI 服务 `langgraph dev` 运行。
|
||||
|
||||
访问地址：http://localhost:2026
|
||||
|
||||
更完整的 Docker 开发说明见 [CONTRIBUTING.md](CONTRIBUTING.md)。
|
||||
|
||||
#### 方式二：本地开发
|
||||
|
||||
如果你更希望直接在本地启动各个服务：
|
||||
|
||||
前提：先完成上面的“配置”步骤（`make config` 和模型 API key 配置）。`make dev` 需要有效配置文件，默认读取项目根目录下的 `config.yaml`，也可以通过 `DEER_FLOW_CONFIG_PATH` 覆盖。
|
||||
在 Windows 上，请使用 Git Bash 运行本地开发流程。基于 bash 的服务脚本不支持直接在原生 `cmd.exe` 或 PowerShell 中执行，且 WSL 也不保证可用，因为部分脚本依赖 Git for Windows 的 `cygpath` 等工具。
|
||||
|
||||
1. **检查依赖环境**：
|
||||
```bash
|
||||
make check # 校验 Node.js 22+、pnpm、uv、nginx
|
||||
```
|
||||
|
||||
2. **安装依赖**：
|
||||
```bash
|
||||
make install # 安装 backend + frontend 依赖
|
||||
```
|
||||
|
||||
3. **（可选）预拉取 sandbox 镜像**：
|
||||
```bash
|
||||
# 如果使用 Docker / Container sandbox，建议先执行
|
||||
make setup-sandbox
|
||||
```
|
||||
|
||||
4. **启动服务**：
|
||||
```bash
|
||||
make dev
|
||||
```
|
||||
|
||||
5. **访问地址**：http://localhost:2026
|
||||
|
||||
### 进阶配置
|
||||
#### Sandbox 模式
|
||||
|
||||
DeerFlow 支持多种 sandbox 执行方式：
|
||||
- **本地执行**（直接在宿主机上运行 sandbox 代码）
|
||||
- **Docker 执行**（在隔离的 Docker 容器里运行 sandbox 代码）
|
||||
- **Docker + Kubernetes 执行**（通过 provisioner 服务在 Kubernetes Pod 中运行 sandbox 代码）
|
||||
|
||||
Docker 开发时，服务启动行为会遵循 `config.yaml` 里的 sandbox 模式。在 Local / Docker 模式下，不会启动 `provisioner`。
|
||||
|
||||
如果要配置你自己的模式，参见 [Sandbox 配置指南](backend/docs/CONFIGURATION.md#sandbox)。

||||
|
||||
#### MCP Server
|
||||
|
||||
DeerFlow 支持可配置的 MCP Server 和 skills，用来扩展能力。
|
||||
对于 HTTP/SSE MCP Server，还支持 OAuth token 流程（`client_credentials`、`refresh_token`）。
|
||||
详细说明见 [MCP Server 指南](backend/docs/MCP_SERVER.md)。
|
||||
|
||||
#### IM 渠道
|
||||
|
||||
DeerFlow 支持从即时通讯应用接收任务。只要配置完成，对应渠道会自动启动，而且都不需要公网 IP。
|
||||
|
||||
| 渠道 | 传输方式 | 上手难度 |
|
||||
|---------|-----------|------------|
|
||||
| Telegram | Bot API（long-polling） | 简单 |
|
||||
| Slack | Socket Mode | 中等 |
|
||||
| Feishu / Lark | WebSocket | 中等 |
|
||||
| 企业微信智能机器人 | WebSocket | 中等 |
|
||||
|
||||
**`config.yaml` 中的配置示例：**
|
||||
|
||||
```yaml
|
||||
channels:
|
||||
# LangGraph Server URL（默认：http://localhost:2024）
|
||||
langgraph_url: http://localhost:2024
|
||||
# Gateway API URL（默认：http://localhost:8001）
|
||||
gateway_url: http://localhost:8001
|
||||
|
||||
# 可选：所有移动端渠道共用的全局 session 默认值
|
||||
session:
|
||||
assistant_id: lead_agent # 也可以填自定义 agent 名；渠道层会自动转换为 lead_agent + agent_name
|
||||
config:
|
||||
recursion_limit: 100
|
||||
context:
|
||||
thinking_enabled: true
|
||||
is_plan_mode: false
|
||||
subagent_enabled: false
|
||||
|
||||
feishu:
|
||||
enabled: true
|
||||
app_id: $FEISHU_APP_ID
|
||||
app_secret: $FEISHU_APP_SECRET
|
||||
# domain: https://open.feishu.cn # 国内版（默认）
|
||||
# domain: https://open.larksuite.com # 国际版
|
||||
|
||||
wecom:
|
||||
enabled: true
|
||||
bot_id: $WECOM_BOT_ID
|
||||
bot_secret: $WECOM_BOT_SECRET
|
||||
|
||||
slack:
|
||||
enabled: true
|
||||
bot_token: $SLACK_BOT_TOKEN # xoxb-...
|
||||
app_token: $SLACK_APP_TOKEN # xapp-...（Socket Mode）
|
||||
allowed_users: [] # 留空表示允许所有人
|
||||
|
||||
telegram:
|
||||
enabled: true
|
||||
bot_token: $TELEGRAM_BOT_TOKEN
|
||||
allowed_users: [] # 留空表示允许所有人
|
||||
|
||||
# 可选：按渠道 / 按用户单独覆盖 session 配置
|
||||
session:
|
||||
assistant_id: mobile-agent # 这里同样支持自定义 agent 名
|
||||
context:
|
||||
thinking_enabled: false
|
||||
users:
|
||||
"123456789":
|
||||
assistant_id: vip-agent
|
||||
config:
|
||||
recursion_limit: 150
|
||||
context:
|
||||
thinking_enabled: true
|
||||
subagent_enabled: true
|
||||
```
|
||||
|
||||
说明：
|
||||
- `assistant_id: lead_agent` 会直接调用默认的 LangGraph assistant。
|
||||
- 如果 `assistant_id` 填的是自定义 agent 名，DeerFlow 仍然会走 `lead_agent`，同时把该值注入为 `agent_name`，这样 IM 渠道也会生效对应 agent 的 SOUL 和配置。
|
||||
|
||||
在 `.env` 里设置对应的 API key：
|
||||
|
||||
```bash
|
||||
# Telegram
|
||||
TELEGRAM_BOT_TOKEN=123456789:ABCdefGHIjklMNOpqrSTUvwxYZ
|
||||
|
||||
# Slack
|
||||
SLACK_BOT_TOKEN=xoxb-...
|
||||
SLACK_APP_TOKEN=xapp-...
|
||||
|
||||
# Feishu / Lark
|
||||
FEISHU_APP_ID=cli_xxxx
|
||||
FEISHU_APP_SECRET=your_app_secret
|
||||
|
||||
# 企业微信智能机器人
|
||||
WECOM_BOT_ID=your_bot_id
|
||||
WECOM_BOT_SECRET=your_bot_secret
|
||||
```
|
||||
|
||||
**Telegram 配置**
|
||||
|
||||
1. 打开 [@BotFather](https://t.me/BotFather)，发送 `/newbot`，复制生成的 HTTP API token。
|
||||
2. 在 `.env` 中设置 `TELEGRAM_BOT_TOKEN`，并在 `config.yaml` 里启用该渠道。
|
||||
|
||||
**Slack 配置**
|
||||
|
||||
1. 前往 [api.slack.com/apps](https://api.slack.com/apps) 创建 Slack App：Create New App → From scratch。
|
||||
2. 在 **OAuth & Permissions** 中添加 Bot Token Scopes：`app_mentions:read`、`chat:write`、`im:history`、`im:read`、`im:write`、`files:write`。
|
||||
3. 启用 **Socket Mode**，生成带 `connections:write` 权限的 App-Level Token（`xapp-...`）。
|
||||
4. 在 **Event Subscriptions** 中订阅 bot events：`app_mention`、`message.im`。
|
||||
5. 在 `.env` 中设置 `SLACK_BOT_TOKEN` 和 `SLACK_APP_TOKEN`，并在 `config.yaml` 中启用该渠道。
|
||||
|
||||
**Feishu / Lark 配置**
|
||||
|
||||
1. 在 [飞书开放平台](https://open.feishu.cn/) 创建应用，并启用 **Bot** 能力。
|
||||
2. 添加权限：`im:message`、`im:message.p2p_msg:readonly`、`im:resource`。
|
||||
3. 在 **事件订阅** 中订阅 `im.message.receive_v1`，连接方式选择 **长连接**。
|
||||
4. 复制 App ID 和 App Secret，在 `.env` 中设置 `FEISHU_APP_ID` 和 `FEISHU_APP_SECRET`，并在 `config.yaml` 中启用该渠道。
|
||||
|
||||
**企业微信智能机器人配置**
|
||||
|
||||
1. 在企业微信智能机器人平台创建机器人，获取 `bot_id` 和 `bot_secret`。
|
||||
2. 在 `config.yaml` 中启用 `channels.wecom`，并填入 `bot_id` / `bot_secret`。
|
||||
3. 在 `.env` 中设置 `WECOM_BOT_ID` 和 `WECOM_BOT_SECRET`。
|
||||
4. 安装后端依赖时确保包含 `wecom-aibot-python-sdk`，渠道会通过 WebSocket 长连接接收消息，无需公网回调地址。
|
||||
5. 当前支持文本、图片和文件入站消息；agent 生成的最终图片/文件也会回传到企业微信会话中。
|
||||
|
||||
**命令**
|
||||
|
||||
渠道连接完成后，你可以直接在聊天窗口里和 DeerFlow 交互：
|
||||
|
||||
| 命令 | 说明 |
|
||||
|---------|-------------|
|
||||
| `/new` | 开启新对话 |
|
||||
| `/status` | 查看当前 thread 信息 |
|
||||
| `/models` | 列出可用模型 |
|
||||
| `/memory` | 查看 memory |
|
||||
| `/help` | 查看帮助 |
|
||||
|
||||
> 没有命令前缀的消息会被当作普通聊天处理。DeerFlow 会自动创建 thread，并以对话方式回复。
|
||||
|
||||
#### LangSmith 链路追踪
|
||||
|
||||
DeerFlow 内置了 [LangSmith](https://smith.langchain.com) 集成，用于可观测性。启用后，所有 LLM 调用、agent 运行和工具执行都会被追踪，并在 LangSmith 仪表盘中展示。
|
||||
|
||||
在 `.env` 文件中添加以下配置：
|
||||
|
||||
```bash
|
||||
LANGSMITH_TRACING=true
|
||||
LANGSMITH_ENDPOINT=https://api.smith.langchain.com
|
||||
LANGSMITH_API_KEY=lsv2_pt_xxxxxxxxxxxxxxxx
|
||||
LANGSMITH_PROJECT=xxx
|
||||
```
|
||||
|
||||
Docker 部署时，追踪默认关闭。在 `.env` 中设置 `LANGSMITH_TRACING=true` 和 `LANGSMITH_API_KEY` 即可启用。
|
||||
|
||||
## 从 Deep Research 到 Super Agent Harness
|
||||
|
||||
DeerFlow 最初是一个 Deep Research 框架，后来社区把它一路推到了更远的地方。上线之后，开发者拿它去做的事情早就不止研究：搭数据流水线、生成演示文稿、快速起 dashboard、自动化内容流程，很多方向一开始连我们自己都没想到。
|
||||
|
||||
这让我们意识到一件事：DeerFlow 不只是一个研究工具。它更像一个 **harness**，一个真正让 agents 把事情做完的运行时基础设施。
|
||||
|
||||
所以我们把它从头重做了一遍。
|
||||
|
||||
DeerFlow 2.0 不再是一个需要你自己拼装的 framework。它是一个开箱即用、同时又足够可扩展的 super agent harness。基于 LangGraph 和 LangChain 构建，默认就带上了 agent 真正会用到的关键能力：文件系统、memory、skills、sandbox 执行环境，以及为复杂多步骤任务做规划、拉起 sub-agents 的能力。
|
||||
|
||||
你可以直接拿来用，也可以拆开重组，改成你自己的样子。
|
||||
|
||||
## 核心特性
|
||||
|
||||
### Skills 与 Tools
|
||||
|
||||
Skills 是 DeerFlow 能做“几乎任何事”的关键。
|
||||
|
||||
标准的 Agent Skill 是一种结构化能力模块，通常就是一个 Markdown 文件，里面定义了工作流、最佳实践，以及相关的参考资源。DeerFlow 自带一批内置 skills，覆盖研究、报告生成、演示文稿制作、网页生成、图像和视频生成等场景。真正有意思的地方在于它的扩展性：你可以加自己的 skills，替换内置 skills，或者把多个 skills 组合成复合工作流。
|
||||
|
||||
Skills 采用按需渐进加载，不会一次性把所有内容都塞进上下文。只有任务确实需要时才加载，这样能把上下文窗口控制得更干净，也更适合对 token 比较敏感的模型。
|
||||
|
||||
通过 Gateway 安装 `.skill` 压缩包时，DeerFlow 会接受标准的可选 frontmatter 元数据，比如 `version`、`author`、`compatibility`，不会把本来合法的外部 skill 拒之门外。
|
||||
|
||||
Tools 也是同样的思路。DeerFlow 自带一组核心工具：网页搜索、网页抓取、文件操作、bash 执行；同时也支持通过 MCP Server 和 Python 函数扩展自定义工具。你可以替换任何一项，也可以继续往里加。
|
||||
|
||||
Gateway 生成后续建议时，现在会先把普通字符串输出和 block/list 风格的富文本内容统一归一化，再去解析 JSON 数组响应，因此不同 provider 的内容包装方式不会再悄悄把建议吞掉。

|

└── your-custom-skill/SKILL.md ← 你的 skill
|
||||
```
|
||||
|
||||
#### Claude Code 集成
|
||||
|
||||
借助 `claude-to-deerflow` skill，你可以直接在 [Claude Code](https://docs.anthropic.com/en/docs/claude-code) 里和正在运行的 DeerFlow 实例交互。不用离开终端，就能下发研究任务、查看状态、管理 threads。
|
||||
|
||||
**安装这个 skill：**
|
||||
|
||||
```bash
|
||||
npx skills add https://github.com/bytedance/deer-flow --skill claude-to-deerflow
|
||||
```
|
||||
|
||||
然后确认 DeerFlow 已经启动（默认地址是 `http://localhost:2026`），在 Claude Code 里使用 `/claude-to-deerflow` 命令即可。
|
||||
|
||||
**你可以做的事情包括：**
|
||||
- 给 DeerFlow 发送消息，并接收流式响应
|
||||
- 选择执行模式：flash（更快）、standard、pro（规划模式）、ultra（sub-agents 模式）
|
||||
- 检查 DeerFlow 健康状态，列出 models / skills / agents
|
||||
- 管理 threads 和会话历史
|
||||
- 上传文件做分析
|
||||
|
||||
**环境变量**（可选，用于自定义端点）：
|
||||
|
||||
```bash
|
||||
DEERFLOW_URL=http://localhost:2026 # 统一代理基地址
|
||||
DEERFLOW_GATEWAY_URL=http://localhost:2026 # Gateway API
|
||||
DEERFLOW_LANGGRAPH_URL=http://localhost:2026/api/langgraph # LangGraph API
|
||||
```
|
||||
|
||||
完整 API 说明见 [`skills/public/claude-to-deerflow/SKILL.md`](skills/public/claude-to-deerflow/SKILL.md)。
|
||||
|
||||
### Sub-Agents
|
||||
|
||||
复杂任务通常不可能一次完成，DeerFlow 会先拆解，再执行。
|
||||
|
||||
lead agent 可以按需动态拉起 sub-agents。每个 sub-agent 都有自己独立的上下文、工具和终止条件。只要条件允许，它们就会并行运行，返回结构化结果，最后再由 lead agent 汇总成一份完整输出。
|
||||
|
||||
这也是 DeerFlow 能处理从几分钟到几小时任务的原因。比如一个研究任务，可以拆成十几个 sub-agents，分别探索不同方向，最后合并成一份报告，或者一个网站，或者一套带生成视觉内容的演示文稿。一个 harness，多路并行。
|
||||
|
||||
### Sandbox 与文件系统
|
||||
|
||||
DeerFlow 不只是“会说它能做”，它是真的有一台自己的“电脑”。
|
||||
|
||||
每个任务都运行在隔离的 Docker 容器里，里面有完整的文件系统，包括 skills、workspace、uploads、outputs。agent 可以读写和编辑文件，可以执行 bash 命令和代码，也可以查看图片。整个过程都在 sandbox 内完成，可审计、会隔离，不会在不同 session 之间互相污染。
|
||||
|
||||
这就是“带工具的聊天机器人”和“真正有执行环境的 agent”之间的差别。
|
||||
|
||||
```text
|
||||
# sandbox 容器内的路径
|
||||
/mnt/user-data/
|
||||
├── uploads/ ← 你的文件
|
||||
├── workspace/ ← agents 的工作目录
|
||||
└── outputs/ ← 最终交付物
|
||||
```
|
||||
|
||||
### Context Engineering
|
||||
|
||||
**隔离的 Sub-Agent Context**：每个 sub-agent 都在自己独立的上下文里运行。它看不到主 agent 的上下文，也看不到其他 sub-agents 的上下文。这样做的目的很直接，就是让它只聚焦当前任务，不被无关信息干扰。
|
||||
|
||||
**摘要压缩**：在单个 session 内，DeerFlow 会比较积极地管理上下文，包括总结已完成的子任务、把中间结果转存到文件系统、压缩暂时不重要的信息。这样在长链路、多步骤任务里，它也能保持聚焦，而不会轻易把上下文窗口打爆。
|
||||
|
||||
### 长期记忆
|
||||
|
||||
大多数 agents 会在对话结束后把一切都忘掉，DeerFlow 不一样。
|
||||
|
||||
跨 session 使用时，DeerFlow 会逐步积累关于你的持久 memory，包括你的个人偏好、知识背景，以及长期沉淀下来的工作习惯。你用得越多，它越了解你的写作风格、技术栈和重复出现的工作流。memory 保存在本地，控制权也始终在你手里。
|
||||
|
||||
## 推荐模型
|
||||
|
||||
DeerFlow 对模型没有强绑定，只要实现了 OpenAI 兼容 API 的 LLM，理论上都可以接入。不过在下面这些能力上表现更强的模型，通常会更适合 DeerFlow：
|
||||
|
||||
- **长上下文窗口**（100k+ tokens），适合深度研究和多步骤任务
|
||||
- **推理能力**，适合自适应规划和复杂拆解
|
||||
- **多模态输入**，适合理解图片和视频
|
||||
- **稳定的 tool use 能力**，适合可靠的函数调用和结构化输出
|
||||
|
||||
## 内嵌 Python Client
|
||||
|
||||
DeerFlow 也可以作为内嵌的 Python 库使用，不必启动完整的 HTTP 服务。`DeerFlowClient` 提供了进程内的直接访问方式，覆盖所有 agent 和 Gateway 能力，返回的数据结构与 HTTP Gateway API 保持一致：
|
||||
|
||||
```python
|
||||
from deerflow.client import DeerFlowClient
|
||||
|
||||
client = DeerFlowClient()
|
||||
|
||||
# Chat
|
||||
response = client.chat("Analyze this paper for me", thread_id="my-thread")
|
||||
|
||||
# Streaming（LangGraph SSE 协议：values、messages-tuple、end）
|
||||
for event in client.stream("hello"):
|
||||
if event.type == "messages-tuple" and event.data.get("type") == "ai":
|
||||
print(event.data["content"])
|
||||
|
||||
# 配置与管理：返回值与 Gateway 对齐的 dict
|
||||
models = client.list_models() # {"models": [...]}
|
||||
skills = client.list_skills() # {"skills": [...]}
|
||||
client.update_skill("web-search", enabled=True)
|
||||
client.upload_files("thread-1", ["./report.pdf"]) # {"success": True, "files": [...]}
|
||||
```
|
||||
|
||||
所有返回 dict 的方法都会在 CI 中通过 Gateway 的 Pydantic 响应模型校验（`TestGatewayConformance`），以确保内嵌 client 始终和 HTTP API schema 保持同步。完整 API 说明见 `backend/packages/harness/deerflow/client.py`。

## ⚠️ 安全使用
|
||||
|
||||
### 不恰当的部署可能导致安全风险
|
||||
|
||||
DeerFlow 具备**系统指令执行、资源操作、业务逻辑调用**等关键高权限能力，默认设计为**部署在本地可信环境（仅本机 127.0.0.1 回环访问）**。若您将 agent 部署至不可信局域网、公网云服务器等可被多终端访问的网络环境，且未采取严格的安全防护措施，可能导致安全风险，例如：
|
||||
|
||||
- **未授权的非法调用**：agent 功能被未授权的第三方、公网恶意扫描程序探测到，进而发起批量非法调用请求，执行系统命令、文件读写等高危操作，可能导致安全后果。
|
||||
- **合规与法律风险**：若 agent 被非法调用用于实施网络攻击、信息窃取等违法违规行为，可能产生法律责任与合规风险。
|
||||
|
||||
### 安全使用建议
|
||||
|
||||
**注意：建议您将 DeerFlow 部署在本地可信的网络环境下。** 若您有跨设备、跨网络的部署需求，必须加入严格的安全措施。例如，采取如下手段：
|
||||
|
||||
- **设置访问 IP 白名单**：使用 `iptables`，或部署硬件防火墙 / 带访问控制（ACL）功能的交换机等，**配置规则设置 IP 白名单**，拒绝其他所有 IP 进行访问。
|
||||
- **前置身份验证**：配置反向代理（nginx 等），并**开启高强度的前置身份验证功能**，禁止无任何身份验证的访问。
|
||||
- **网络隔离**：若有可能，建议将 agent 和可信设备划分到**同一个专用 VLAN**，与其他网络设备做隔离。
|
||||
- **持续关注项目更新**：请持续关注 DeerFlow 项目的安全功能更新。

## Architecture
|
||||
|
||||
### Harness / App Split
|
||||
|
||||
The backend is split into two layers with a strict dependency direction:
|
||||
|
||||
- **Harness** (`packages/harness/deerflow/`): Publishable agent framework package (`deerflow-harness`). Import prefix: `deerflow.*`. Contains agent orchestration, tools, sandbox, models, MCP, skills, config — everything needed to build and run agents.
|
||||
- **App** (`app/`): Unpublished application code. Import prefix: `app.*`. Contains the FastAPI Gateway API and IM channel integrations (Feishu, Slack, Telegram).
|
||||
|
||||
**Dependency rule**: App imports deerflow, but deerflow never imports app. This boundary is enforced by `tests/test_harness_boundary.py` which runs in CI.
|
||||
|
||||
**Import conventions**:
|
||||
```python
|
||||
# Harness internal
|
||||
from deerflow.agents import make_lead_agent
|
||||
from deerflow.models import create_chat_model
|
||||
|
||||
# App internal
|
||||
from app.gateway.app import app
|
||||
from app.channels.service import start_channel_service
|
||||
|
||||
# App → Harness (allowed)

||||

Setup: Copy `config.example.yaml` to `config.yaml` in the **project root** directory.

**Config Versioning**: `config.example.yaml` has a `config_version` field. On startup, `AppConfig.from_file()` compares user version vs example version and emits a warning if outdated.

||||
### IM Channels System (`app/channels/`)
|
||||
|
||||
Bridges external messaging platforms (Feishu, Slack, Telegram) to the DeerFlow agent via the LangGraph Server.
|
||||
|
||||
**Architecture**: Channels communicate with the LangGraph Server through `langgraph-sdk` HTTP client (same as the frontend), ensuring threads are created and managed server-side.
|
||||
### Memory System (`src/agents/memory/`)
|
||||
|
||||
**Components**:
|
||||
- `message_bus.py` - Async pub/sub hub (`InboundMessage` → queue → dispatcher; `OutboundMessage` → callbacks → channels)
|
||||
- `store.py` - JSON-file persistence mapping `channel_name:chat_id[:topic_id]` → `thread_id` (keys are `channel:chat` for root conversations and `channel:chat:topic` for threaded conversations)
|
||||
- `manager.py` - Core dispatcher: creates threads via `client.threads.create()`, routes commands, keeps Slack/Telegram on `client.runs.wait()`, and uses `client.runs.stream(["messages-tuple", "values"])` for Feishu incremental outbound updates
|
||||
- `base.py` - Abstract `Channel` base class (start/stop/send lifecycle)
|
||||
- `service.py` - Manages lifecycle of all configured channels from `config.yaml`
|
||||
- `slack.py` / `feishu.py` / `telegram.py` - Platform-specific implementations (`feishu.py` tracks the running card `message_id` in memory and patches the same card in place)
|
||||
|
||||
**Message Flow**:
|
||||
1. External platform -> Channel impl -> `MessageBus.publish_inbound()`
|
||||
2. `ChannelManager._dispatch_loop()` consumes from queue
|
||||
3. For chat: look up/create thread on LangGraph Server
|
||||
4. Feishu chat: `runs.stream()` → accumulate AI text → publish multiple outbound updates (`is_final=False`) → publish final outbound (`is_final=True`)
|
||||
5. Slack/Telegram chat: `runs.wait()` → extract final response → publish outbound
|
||||
6. Feishu channel sends one running reply card up front, then patches the same card for each outbound update (card JSON sets `config.update_multi=true` for Feishu's patch API requirement)
|
||||
7. For commands (`/new`, `/status`, `/models`, `/memory`, `/help`): handle locally or query Gateway API
|
||||
8. Outbound → channel callbacks → platform reply
|
||||
|
||||
**Configuration** (`config.yaml` -> `channels`):
|
||||
- `langgraph_url` - LangGraph Server URL (default: `http://localhost:2024`)
|
||||
- `gateway_url` - Gateway API URL for auxiliary commands (default: `http://localhost:8001`)
|
||||

`DeerFlowClient` provides direct in-process access to all DeerFlow capabilities without HTTP services. All return types align with the Gateway API response schemas, so consumer code works identically in HTTP and embedded modes.

|

**Agent Conversation** (replaces LangGraph Server):
|
||||
- `chat(message, thread_id)` — synchronous, accumulates streaming deltas per message-id and returns the final AI text
|
||||
- `stream(message, thread_id)` — subscribes to LangGraph `stream_mode=["values", "messages", "custom"]` and yields `StreamEvent`:
|
||||
- `"values"` — full state snapshot (title, messages, artifacts); AI text already delivered via `messages` mode is **not** re-synthesized here to avoid duplicate deliveries
|
||||
- `"messages-tuple"` — per-chunk update: for AI text this is a **delta** (concat per `id` to rebuild the full message); tool calls and tool results are emitted once each
|
||||
- `"custom"` — forwarded from `StreamWriter`
|
||||
- `"end"` — stream finished (carries cumulative `usage` counted once per message id)
|
||||
- `chat(message, thread_id)` — synchronous, returns final text
|
||||
- `stream(message, thread_id)` — yields `StreamEvent` aligned with LangGraph SSE protocol:
|
||||
- `"values"` — full state snapshot (title, messages, artifacts)
|
||||
- `"messages-tuple"` — per-message update (AI text, tool calls, tool results)
|
||||
- `"end"` — stream finished
|
||||
- Agent created lazily via `create_agent()` + `_build_middlewares()`, same as `make_lead_agent`
|
||||
- Supports `checkpointer` parameter for state persistence across turns
|
||||
- `reset_agent()` forces agent recreation (e.g. after memory or skill changes)
|
||||
- See [docs/STREAMING.md](docs/STREAMING.md) for the full design: why Gateway and DeerFlowClient are parallel paths, LangGraph's `stream_mode` semantics, the per-id dedup invariants, and regression testing strategy

### IM Channels
|
||||
|
||||
The IM bridge supports Feishu, Slack, and Telegram. Slack and Telegram still use the final `runs.wait()` response path, while Feishu now streams through `runs.stream(["messages-tuple", "values"])` and updates a single in-thread card in place.
|
||||
|
||||
For Feishu card updates, DeerFlow stores the running card's `message_id` per inbound message and patches that same card until the run finishes, preserving the existing `OK` / `DONE` reaction flow.

### LangSmith Tracing
|
||||
|
||||
DeerFlow has built-in [LangSmith](https://smith.langchain.com) integration for observability. When enabled, all LLM calls, agent runs, tool executions, and middleware processing are traced and visible in the LangSmith dashboard.
|
||||
|
||||
**Setup:**
|
||||
|
||||
1. Sign up at [smith.langchain.com](https://smith.langchain.com) and create a project.
|
||||
2. Add the following to your `.env` file in the project root:
|
||||
|
||||
```bash
|
||||
LANGSMITH_TRACING=true
|
||||
LANGSMITH_ENDPOINT=https://api.smith.langchain.com
|
||||
LANGSMITH_API_KEY=lsv2_pt_xxxxxxxxxxxxxxxx
|
||||
LANGSMITH_PROJECT=xxx
|
||||
```
|
||||
|
||||
**Legacy variables:** The `LANGCHAIN_TRACING_V2`, `LANGCHAIN_API_KEY`, `LANGCHAIN_PROJECT`, and `LANGCHAIN_ENDPOINT` variables are also supported for backward compatibility. `LANGSMITH_*` variables take precedence when both are set.
|
||||
|
||||
### Langfuse Tracing
|
||||
|
||||
DeerFlow also supports [Langfuse](https://langfuse.com) observability for LangChain-compatible runs.
|
||||
|
||||
Add the following to your `.env` file:
|
||||
|
||||
```bash
|
||||
LANGFUSE_TRACING=true
|
||||
LANGFUSE_PUBLIC_KEY=pk-lf-xxxxxxxxxxxxxxxx
|
||||
LANGFUSE_SECRET_KEY=sk-lf-xxxxxxxxxxxxxxxx
|
||||
LANGFUSE_BASE_URL=https://cloud.langfuse.com
|
||||
```
|
||||
|
||||
If you are using a self-hosted Langfuse deployment, set `LANGFUSE_BASE_URL` to your Langfuse host.
|
||||
|
||||
### Dual Provider Behavior
|
||||
|
||||
If both LangSmith and Langfuse are enabled, DeerFlow initializes and attaches both callbacks so the same run data is reported to both systems.
|
||||
|
||||
If a provider is explicitly enabled but required credentials are missing, or the provider callback cannot be initialized, DeerFlow raises an error when tracing is initialized during model creation instead of silently disabling tracing.
|
||||
|
||||
**Docker:** In `docker-compose.yaml`, tracing is disabled by default (`LANGSMITH_TRACING=false`). Set `LANGSMITH_TRACING=true` and/or `LANGFUSE_TRACING=true` in your `.env`, together with the required credentials, to enable tracing in containerized deployments.

**Stream Mode Compatibility:**
|
||||
- Use: `values`, `messages-tuple`, `custom`, `updates`, `events`, `debug`, `tasks`, `checkpoints`
|
||||
- Do not use: `tools` (deprecated/invalid in current `langgraph-api` and will trigger schema validation errors)
|
||||
|
||||
**Recursion Limit:**
|
||||
|
||||
`config.recursion_limit` caps the number of graph steps LangGraph will execute
|
||||
in a single run. The `/api/langgraph/*` endpoints go straight to the LangGraph
|
||||
server and therefore inherit LangGraph's native default of **25**, which is
|
||||
too low for plan-mode or subagent-heavy runs — the agent typically errors out
|
||||
with `GraphRecursionError` after the first round of subagent results comes
|
||||
back, before the lead agent can synthesize the final answer.
|
||||
|
||||
DeerFlow's own Gateway and IM-channel paths mitigate this by defaulting to
|
||||
`100` in `build_run_config` (see `backend/app/gateway/services.py`), but
|
||||
clients calling the LangGraph API directly must set `recursion_limit`
|
||||
explicitly in the request body. `100` matches the Gateway default and is a
|
||||
safe starting point; increase it if you run deeply nested subagent graphs.
|
||||
|
||||
**Configurable Options:**
|
||||
- `model_name` (string): Override the default model
|
||||
- `thinking_enabled` (boolean): Enable extended thinking for supported models

# Docker Test Gap (Section 七 7.4)
|
||||
|
||||
This file documents the only **un-executed** test cases from
|
||||
`backend/docs/AUTH_TEST_PLAN.md` after the full release validation pass.
|
||||
|
||||
## Why this gap exists
|
||||
|
||||
The release validation environment (sg_dev: `10.251.229.92`) **does not have
|
||||
a Docker daemon installed**. The TC-DOCKER cases are container-runtime
|
||||
behavior tests that need an actual Docker engine to spin up
|
||||
`docker/docker-compose.yaml` services.
|
||||
|
||||
```bash
|
||||
$ ssh sg_dev "which docker; docker --version"
|
||||
# (empty)
|
||||
# bash: docker: command not found
|
||||
```
|
||||
|
||||
All other test plan sections were executed against either:
|
||||
- The local dev box (Mac, all services running locally), or
|
||||
- The deployed sg_dev instance (gateway + frontend + nginx via SSH tunnel)
|
||||
|
||||
## Cases not executed
|
||||
|
||||
| Case | Title | What it covers | Why not run |
|
||||
|---|---|---|---|
|
||||
| TC-DOCKER-01 | `users.db` volume persistence | Verify the `DEER_FLOW_HOME` bind mount survives container restart | needs `docker compose up` |
|
||||
| TC-DOCKER-02 | Session persistence across container restart | `AUTH_JWT_SECRET` env var keeps cookies valid after `docker compose down && up` | needs `docker compose down/up` |
|
||||
| TC-DOCKER-03 | Per-worker rate limiter divergence | Confirms in-process `_login_attempts` dict doesn't share state across `gunicorn` workers (4 by default in the compose file); known limitation, documented | needs multi-worker container |
|
||||
| TC-DOCKER-04 | IM channels skip AuthMiddleware | Verify Feishu/Slack/Telegram dispatchers run in-container against `http://langgraph:2024` without going through nginx | needs `docker logs` |
|
||||
| TC-DOCKER-05 | Admin credentials surfacing | **Updated post-simplify** — was "log scrape", now "0600 credential file in `DEER_FLOW_HOME`". The file-based behavior is already validated by TC-1.1 + TC-UPG-13 on sg_dev (non-Docker), so the only Docker-specific gap is verifying the volume mount carries the file out to the host | needs container + host volume |
|
||||
| TC-DOCKER-06 | Gateway-mode Docker deploy | `./scripts/deploy.sh --gateway` produces a 3-container topology (no `langgraph` container); same auth flow as standard mode | needs `docker compose --profile gateway` |
|
||||
|
||||
## Coverage already provided by non-Docker tests
|
||||
|
||||
The **auth-relevant** behavior in each Docker case is already exercised by
|
||||
the test cases that ran on sg_dev or local:
|
||||
|
||||
| Docker case | Auth behavior covered by |
|
||||
|---|---|
|
||||
| TC-DOCKER-01 (volume persistence) | TC-REENT-01 on sg_dev (admin row survives gateway restart) — same SQLite file, just no container layer between |
|
||||
| TC-DOCKER-02 (session persistence) | TC-API-02/03/06 (cookie roundtrip), plus TC-REENT-04 (multi-cookie) — JWT verification is process-state-free, container restart is equivalent to `pkill uvicorn && uv run uvicorn` |
|
||||
| TC-DOCKER-03 (per-worker rate limit) | TC-GW-04 + TC-REENT-09 (single-worker rate limit + 5min expiry). The cross-worker divergence is an architectural property of the in-memory dict; no auth code path differs |
|
||||
| TC-DOCKER-04 (IM channels skip auth) | Code-level only: `app/channels/manager.py` uses `langgraph_sdk` directly with no cookie handling. The langgraph_auth handler is bypassed by going through SDK, not HTTP |
|
||||
| TC-DOCKER-05 (credential surfacing) | TC-1.1 on sg_dev (file at `~/deer-flow/backend/.deer-flow/admin_initial_credentials.txt`, mode 0600, password 22 chars) — the only Docker-unique step is whether the bind mount projects this path onto the host, which is a `docker compose` config check, not a runtime behavior change |
|
||||
| TC-DOCKER-06 (gateway-mode container) | Section 七 7.2 covered by TC-GW-01..05 + Section 二 (gateway-mode auth flow on sg_dev) — same Gateway code, container is just a packaging change |
|
||||
|
||||
## Reproduction steps when Docker becomes available
|
||||
|
||||
Anyone with `docker` + `docker compose` installed can reproduce the gap by
|
||||
running the test plan section verbatim. Pre-flight:
|
||||
|
||||
```bash
|
||||
# Required on the host
|
||||
docker --version # >=24.x
|
||||
docker compose version # plugin >=2.x
|
||||
|
||||
# Required env var (otherwise sessions reset on every container restart)
|
||||
echo "AUTH_JWT_SECRET=$(python3 -c 'import secrets; print(secrets.token_urlsafe(32))')" \
|
||||
>> .env
|
||||
|
||||
# Optional: pin DEER_FLOW_HOME to a stable host path
|
||||
echo "DEER_FLOW_HOME=$HOME/deer-flow-data" >> .env
|
||||
```
|
||||
|
||||
Then run TC-DOCKER-01..06 from the test plan as written.
|
||||
|
||||
## Decision log
|
||||
|
||||
- **Not blocking the release.** The auth-relevant behavior in every Docker
|
||||
case has an already-validated equivalent on bare metal. The gap is purely
|
||||
about *container packaging* details (bind mounts, multi-worker, log
|
||||
collection), not about whether the auth code paths work.
|
||||
- **TC-DOCKER-05 was updated in place** in `AUTH_TEST_PLAN.md` to reflect
|
||||
the post-simplify reality (credentials file → 0600 file, no log leak).
|
||||
The old "grep 'Password:' in docker logs" expectation would have failed
|
||||
silently and given a false sense of coverage.

# Authentication Upgrade Guide
|
||||
|
||||
DeerFlow 内置了认证模块。本文档面向从无认证版本升级的用户。
|
||||
|
||||
## 核心概念
|
||||
|
||||
认证模块采用**始终强制**策略：
|
||||
|
||||
- 首次启动时自动创建 admin 账号，随机密码打印到控制台日志
|
||||
- 认证从一开始就是强制的，无竞争窗口
|
||||
- 历史对话（升级前创建的 thread）自动迁移到 admin 名下
|
||||
|
||||
## 升级步骤
|
||||
|
||||
### 1. 更新代码
|
||||
|
||||
```bash
|
||||
git pull origin main
|
||||
cd backend && make install
|
||||
```
|
||||
|
||||
### 2. 首次启动
|
||||
|
||||
```bash
|
||||
make dev
|
||||
```
|
||||
|
||||
控制台会输出：
|
||||
|
||||
```
|
||||
============================================================
|
||||
Admin account created on first boot
|
||||
Email: admin@deerflow.dev
|
||||
Password: aB3xK9mN_pQ7rT2w
|
||||
Change it after login: Settings → Account
|
||||
============================================================
|
||||
```
|
||||
|
||||
如果未登录就重启了服务，不用担心——只要 setup 未完成，每次启动都会重置密码并重新打印到控制台。
|
||||
|
||||
### 3. 登录
|
||||
|
||||
访问 `http://localhost:2026/login`，使用控制台输出的邮箱和密码登录。
|
||||
|
||||
### 4. 修改密码
|
||||
|
||||
登录后进入 Settings → Account → Change Password。
|
||||
|
||||
### 5. 添加用户（可选）
|
||||
|
||||
其他用户通过 `/login` 页面注册，自动获得 **user** 角色。每个用户只能看到自己的对话。
|
||||
|
||||
## 安全机制
|
||||
|
||||
| 机制 | 说明 |
|
||||
|------|------|
|
||||
| JWT HttpOnly Cookie | Token 不暴露给 JavaScript，防止 XSS 窃取 |
|
||||
| CSRF Double Submit Cookie | 所有 POST/PUT/DELETE 请求需携带 `X-CSRF-Token` |
|
||||
| bcrypt 密码哈希 | 密码不以明文存储 |
|
||||
| 多租户隔离 | 用户只能访问自己的 thread |
|
||||
| HTTPS 自适应 | 检测 `x-forwarded-proto`，自动设置 `Secure` cookie 标志 |
|
||||
|
||||
## 常见操作
|
||||
|
||||
### 忘记密码
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
|
||||
# 重置 admin 密码
|
||||
python -m app.gateway.auth.reset_admin
|
||||
|
||||
# 重置指定用户密码
|
||||
python -m app.gateway.auth.reset_admin --email user@example.com
|
||||
```
|
||||
|
||||
会输出新的随机密码。
|
||||
|
||||
### 完全重置
|
||||
|
||||
删除用户数据库，重启后自动创建新 admin：
|
||||
|
||||
```bash
|
||||
rm -f backend/.deer-flow/users.db
|
||||
# 重启服务，控制台输出新密码
|
||||
```
|
||||
|
||||
## 数据存储
|
||||
|
||||
| 文件 | 内容 |
|
||||
|------|------|
|
||||
| `.deer-flow/users.db` | SQLite 用户数据库（密码哈希、角色） |
|
||||
| `.env` 中的 `AUTH_JWT_SECRET` | JWT 签名密钥（未设置时自动生成临时密钥，重启后 session 失效） |
|
||||
|
||||
### 生产环境建议
|
||||
|
||||
```bash
|
||||
# 生成持久化 JWT 密钥，避免重启后所有用户需重新登录
|
||||
python -c "import secrets; print(secrets.token_urlsafe(32))"
|
||||
# 将输出添加到 .env：
|
||||
# AUTH_JWT_SECRET=<生成的密钥>
|
||||
```
|
||||
|
||||
## API 端点
|
||||
|
||||
| 端点 | 方法 | 说明 |
|
||||
|------|------|------|
|
||||
| `/api/v1/auth/login/local` | POST | 邮箱密码登录（OAuth2 form） |
|
||||
| `/api/v1/auth/register` | POST | 注册新用户（user 角色） |
|
||||
| `/api/v1/auth/logout` | POST | 登出（清除 cookie） |
|
||||
| `/api/v1/auth/me` | GET | 获取当前用户信息 |
|
||||
| `/api/v1/auth/change-password` | POST | 修改密码 |
|
||||
| `/api/v1/auth/setup-status` | GET | 检查 admin 是否存在 |
|
||||
|
||||
## 兼容性
|
||||
|
||||
- **标准模式**（`make dev`）：完全兼容，admin 自动创建
|
||||
- **Gateway 模式**（`make dev-pro`）：完全兼容
|
||||
- **Docker 部署**：完全兼容，`.deer-flow/users.db` 需持久化卷挂载
|
||||
- **IM 渠道**（Feishu/Slack/Telegram）：通过 LangGraph SDK 通信，不经过认证层
|
||||
- **DeerFlowClient**（嵌入式）：不经过 HTTP，不受认证影响
|
||||
|
||||
## 故障排查
|
||||
|
||||
| 症状 | 原因 | 解决 |
|
||||
|------|------|------|
|
||||
| 启动后没看到密码 | admin 已存在（非首次启动） | 用 `reset_admin` 重置，或删 `users.db` |
|
||||
| 登录后 POST 返回 403 | CSRF token 缺失 | 确认前端已更新 |
|
||||
| 重启后需要重新登录 | `AUTH_JWT_SECRET` 未持久化 | 在 `.env` 中设置固定密钥 |

|
||||
使用 `TitleMiddleware` 在 `after_agent` 钩子中：
|
||||
1. 检测是否是首次对话（1个用户消息 + 1个助手回复）
|
||||
2. 检查 state 是否已有 title
|
||||
3. 调用 LLM 生成简洁的标题（默认最多6个词）
|
||||
4. 将 title 存储到 `ThreadState` 中（会被 checkpointer 持久化）
|
||||

TitleMiddleware 会先把 LangChain message content 里的结构化 block/list 内容归一化为纯文本，再拼到 title prompt 里，避免把 Python/JSON 的原始 repr 泄漏到标题生成模型。

This guide explains how to configure DeerFlow for your environment.
|
||||
|
||||
## Config Versioning
|
||||
|
||||
`config.example.yaml` contains a `config_version` field that tracks schema changes. When the example version is higher than your local `config.yaml`, the application emits a startup warning:
|
||||
|
||||
```
|
||||
WARNING - Your config.yaml (version 0) is outdated — the latest version is 1.
|
||||
Run `make config-upgrade` to merge new fields into your config.
|
||||
```
|
||||
|
||||
- **Missing `config_version`** in your config is treated as version 0.
|
||||
- Run `make config-upgrade` to auto-merge missing fields (your existing values are preserved, a `.bak` backup is created).
|
||||
- When changing the config schema, bump `config_version` in `config.example.yaml`.

|

**Auth behavior for CLI-backed providers**:
|
||||
- `CodexChatModel` loads Codex CLI auth from `~/.codex/auth.json`
|
||||
- The Codex Responses endpoint currently rejects `max_tokens` and `max_output_tokens`, so `CodexChatModel` does not expose a request-level token cap
|
||||
- `ClaudeChatModel` accepts `CLAUDE_CODE_OAUTH_TOKEN`, `ANTHROPIC_AUTH_TOKEN`, `CLAUDE_CODE_OAUTH_TOKEN_FILE_DESCRIPTOR`, `CLAUDE_CODE_CREDENTIALS_PATH`, or plaintext `~/.claude/.credentials.json`
|
||||
- On macOS, DeerFlow does not probe Keychain automatically. Use `scripts/export_claude_code_oauth.py` to export Claude Code auth explicitly when needed

**Gemini with thinking via OpenAI-compatible gateway**:
|
||||
|
||||
When routing Gemini through an OpenAI-compatible proxy (Vertex AI OpenAI compat endpoint, AI Studio, or third-party gateways) with thinking enabled, the API attaches a `thought_signature` to each tool-call object returned in the response. Every subsequent request that replays those assistant messages **must** echo those signatures back on the tool-call entries or the API returns:
|
||||

||||
```

HTTP 400 INVALID_ARGUMENT: function call `<tool>` in the N. content block is
|
||||
missing a `thought_signature`.
|

```
|
||||
|
||||
Standard `langchain_openai:ChatOpenAI` silently drops `thought_signature` when serialising messages. Use `deerflow.models.patched_openai:PatchedChatOpenAI` instead — it re-injects the tool-call signatures (sourced from `AIMessage.additional_kwargs["tool_calls"]`) into every outgoing payload:

When you configure `sandbox.mounts`, DeerFlow exposes those `container_path` values in the agent prompt so the agent can discover and operate on mounted directories directly instead of assuming everything must live under `/mnt/user-data`.

# Guardrails: Pre-Tool-Call Authorization
|
||||
|
||||
> **Context:** [Issue #1213](https://github.com/bytedance/deer-flow/issues/1213) — DeerFlow has Docker sandboxing and human approval via `ask_clarification`, but no deterministic, policy-driven authorization layer for tool calls. An agent running autonomous multi-step tasks can execute any loaded tool with any arguments. Guardrails add a middleware that evaluates every tool call against a policy **before** execution.
|
||||
|
||||
## Why Guardrails
|
||||
|
||||
```
|
||||
Without guardrails: With guardrails:

||||

Tool runs Agent sees:
|
||||
normally "Guardrail denied:
|
||||
rm -rf blocked"
|
||||
```
|
||||
|
||||
- **Sandboxing** provides process isolation but not semantic authorization. A sandboxed `bash` can still `curl` data out.
|
||||
- **Human approval** (`ask_clarification`) requires a human in the loop for every action. Not viable for autonomous workflows.
|
||||
- **Guardrails** provide deterministic, policy-driven authorization that works without human intervention.

Built-in OAP Passport Custom
|
||||
Allowlist Provider Provider
|
||||
(zero dep) (open standard) (your code)
|
||||
│
|
||||
Any implementation
|
||||
(e.g. APort, or
|
||||
your own evaluator)
|
||||
```
|
||||
|
||||
The `GuardrailMiddleware` implements `wrap_tool_call` / `awrap_tool_call` (the same `AgentMiddleware` pattern used by `ToolErrorHandlingMiddleware`). It:
|
||||
|
||||
1. Builds a `GuardrailRequest` with tool name, arguments, and passport reference
|
||||
2. Calls `provider.evaluate(request)` on whatever provider is configured
|
||||
3. If **deny**: returns `ToolMessage(status="error")` with the reason -- agent sees the denial and adapts
|
||||
4. If **allow**: passes through to the actual tool handler
|
||||
5. If **provider error** and `fail_closed=true` (default): blocks the call
|
||||
6. `GraphBubbleUp` exceptions (LangGraph control signals) are always propagated, never caught
|
||||
|
||||
## Three Provider Options
|
||||
|
||||
### Option 1: Built-in AllowlistProvider (Zero Dependencies)
|
||||
|
||||
The simplest option. Ships with DeerFlow. Block or allow tools by name. No external packages, no passport, no network.
|
||||
|
||||
**config.yaml:**
|
||||
```yaml
|
||||
guardrails:
|
||||
enabled: true
|
||||
provider:
|
||||
use: deerflow.guardrails.builtin:AllowlistProvider
|
||||
config:
|
||||
denied_tools: ["bash", "write_file"]
|
||||
```
|
||||
|
||||
This blocks `bash` and `write_file` for all requests. All other tools pass through.
|
||||
|
||||
You can also use an allowlist (only these tools are permitted):
|
||||
```yaml
|
||||
guardrails:
|
||||
enabled: true
|
||||
provider:
|
||||
use: deerflow.guardrails.builtin:AllowlistProvider
|
||||
config:
|
||||
allowed_tools: ["web_search", "read_file", "ls"]
|
||||
```
|
||||
|
||||
**Try it:**
|
||||
1. Add the config above to your `config.yaml`
|
||||
2. Start DeerFlow: `make dev`
|
||||
3. Ask the agent: "Use bash to run echo hello"
|
||||
4. The agent sees: `Guardrail denied: tool 'bash' was blocked (oap.tool_not_allowed)`
|
||||
|
||||
### Option 2: OAP Passport Provider (Policy-Based)
|
||||
|
||||
For policy enforcement based on the [Open Agent Passport (OAP)](https://github.com/aporthq/aport-spec) open standard. An OAP passport is a JSON document that declares an agent's identity, capabilities, and operational limits. Any provider that reads an OAP passport and returns OAP-compliant decisions works with DeerFlow.
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────────────────────────────┐
|
||||
│ OAP Passport (JSON) │
|
||||

||||

|
||||
│ ], │
|
||||
│ "limits": { │
|
||||
│ "system.command.execute": { │

|
||||
Your own APort (ref. Other future
|
||||
evaluator implementation) implementations
|
||||
```
|
||||
|
||||
**Creating a passport manually:**
|
||||
|
||||
An OAP passport is just a JSON file. You can create one by hand following the [OAP specification](https://github.com/aporthq/aport-spec/blob/main/oap/oap-spec.md) and validate it against the [JSON schema](https://github.com/aporthq/aport-spec/blob/main/oap/passport-schema.json). See the [examples](https://github.com/aporthq/aport-spec/tree/main/oap/examples) directory for templates.
|
||||
|
||||
**Using APort as a reference implementation:**
|
||||
|
||||
[APort Agent Guardrails](https://github.com/aporthq/aport-agent-guardrails) is one open-source (Apache 2.0) implementation of an OAP provider. It handles passport creation, local evaluation, and optional hosted API evaluation.
|
||||
|
||||
```bash
|
||||
pip install aport-agent-guardrails
|
||||
aport setup --framework deerflow
|
||||
```
|
||||
|
||||
This creates:
|
||||
- `~/.aport/deerflow/config.yaml` -- evaluator config (local or API mode)
|
||||
- `~/.aport/deerflow/aport/passport.json` -- OAP passport with capabilities and limits
|
||||
|
||||
**config.yaml (using APort as the provider):**
|
||||
```yaml
|
||||
guardrails:
|
||||
enabled: true
|
||||
provider:
|
||||
use: aport_guardrails.providers.generic:OAPGuardrailProvider
|
||||
```
|
||||
|
||||
**config.yaml (using your own OAP provider):**
|
||||
```yaml
|
||||
guardrails:
|
||||
enabled: true
|
||||
provider:
|
||||
use: my_oap_provider:MyOAPProvider
|
||||
config:
|
||||
passport_path: ./my-passport.json
|
||||
```
|
||||
|
||||
Any provider that accepts `framework` as a kwarg and implements `evaluate`/`aevaluate` works. The OAP standard defines the passport format and decision codes; DeerFlow doesn't care which provider reads them.
|
||||
|
||||
**What the passport controls:**
|
||||
|
||||
| Passport field | What it does | Example |
|
||||
|---|---|---|
|
||||
| `capabilities[].id` | Which tool categories the agent can use | `system.command.execute`, `data.file.write` |
|
||||
| `limits.*.allowed_commands` | Which commands are allowed | `["git", "npm", "node"]` or `["*"]` for all |
|
||||
| `limits.*.blocked_patterns` | Patterns always denied | `["rm -rf", "sudo", "chmod 777"]` |
|
||||
| `status` | Kill switch | `active`, `suspended`, `revoked` |
|
||||
|
||||
**Evaluation modes (provider-dependent):**
|
||||
|
||||
OAP providers may support different evaluation modes. For example, the APort reference implementation supports:
|
||||
|
||||
| Mode | How it works | Network | Latency |
|
||||
|---|---|---|---|
|
||||
| **Local** | Evaluates passport locally (bash script). | None | ~300ms |
|
||||
| **API** | Sends passport + context to a hosted evaluator. Signed decisions. | Yes | ~65ms |
|
||||
|
||||
A custom OAP provider can implement any evaluation strategy -- the DeerFlow middleware doesn't care how the provider reaches its decision.
|
||||
|
||||
**Try it:**
|
||||
1. Install and set up as above
|
||||
2. Start DeerFlow and ask: "Create a file called test.txt with content hello"
|
||||
3. Then ask: "Now delete it using bash rm -rf"
|
||||
4. Guardrail blocks it: `oap.blocked_pattern: Command contains blocked pattern: rm -rf`
|
||||
|
||||
### Option 3: Custom Provider (Bring Your Own)
|
||||
|
||||
Any Python class with `evaluate(request)` and `aevaluate(request)` methods works. No base class or inheritance needed -- it's a structural protocol.
|
||||
|
||||
```python
|
||||
# my_guardrail.py
|
||||
|
||||
class MyGuardrailProvider:
|
||||
name = "my-company"
|
||||
|
||||
def evaluate(self, request):
|
||||
from deerflow.guardrails.provider import GuardrailDecision, GuardrailReason
|
||||
|
||||
# Example: block any bash command containing "delete"
|
||||
if request.tool_name == "bash" and "delete" in str(request.tool_input):
|
||||
return GuardrailDecision(
|
||||
allow=False,
|
||||
reasons=[GuardrailReason(code="custom.blocked", message="delete not allowed")],
|
||||
policy_id="custom.v1",
|
||||
)
|
||||
return GuardrailDecision(allow=True, reasons=[GuardrailReason(code="oap.allowed")])
|
||||
|
||||
async def aevaluate(self, request):
|
||||
return self.evaluate(request)
|
||||
```
|
||||
|
||||
**config.yaml:**
|
||||
```yaml
|
||||
guardrails:
|
||||
enabled: true
|
||||
provider:
|
||||
use: my_guardrail:MyGuardrailProvider
|
||||
```
|
||||
|
||||
Make sure `my_guardrail.py` is on the Python path (e.g. in the backend directory or installed as a package).
|
||||
|
||||
**Try it:**
|
||||
1. Create `my_guardrail.py` in the backend directory
|
||||
2. Add the config
|
||||
3. Start DeerFlow and ask: "Use bash to delete test.txt"
|
||||
4. Your provider blocks it

|

```
|
||||
|
||||
### DeerFlow Tool Names
|
||||
|
||||
These are the tool names your provider will see in `request.tool_name`:
|
||||
|
||||
| Tool | What it does |
|
||||
|---|---|
|
||||
| `bash` | Shell command execution |
|
||||
| `write_file` | Create/overwrite a file |
|
||||
| `str_replace` | Edit a file (find and replace) |
|
||||
| `read_file` | Read file content |
|
||||
| `ls` | List directory |
|
||||
| `web_search` | Web search query |
|
||||
| `web_fetch` | Fetch URL content |
|
||||
| `image_search` | Image search |
|
||||
| `present_file` | Present file to user |
|
||||
| `view_image` | Display image |
|
||||
| `ask_clarification` | Ask user a question |
|
||||
| `task` | Delegate to subagent |
|
||||
| `mcp__*` | MCP tools (dynamic) |
|
||||
|
||||
### OAP Reason Codes
|
||||
|
||||
Standard codes used by the [OAP specification](https://github.com/aporthq/aport-spec):
|
||||
|
||||
| Code | Meaning |
|
||||
|---|---|
|
||||
| `oap.allowed` | Tool call authorized |
|
||||
| `oap.tool_not_allowed` | Tool not in allowlist |
|
||||
| `oap.command_not_allowed` | Command not in allowed_commands |
|
||||
| `oap.blocked_pattern` | Command matches a blocked pattern |
|
||||
| `oap.limit_exceeded` | Operation exceeds a limit |
|
||||
| `oap.passport_suspended` | Passport status is suspended/revoked |
|
||||
| `oap.evaluator_error` | Provider crashed (fail-closed) |
|
||||
|
||||
### Provider Loading
|
||||
|
||||
DeerFlow loads providers via `resolve_variable()` -- the same mechanism used for models, tools, and sandbox providers. The `use:` field is a Python class path: `package.module:ClassName`.
|
||||
|
||||
The provider is instantiated with `**config` kwargs if `config:` is set, plus `framework="deerflow"` is always injected. Accept `**kwargs` to stay forward-compatible:
|
||||
|
||||
```python
|
||||
class YourProvider:
|
||||
def __init__(self, framework: str = "generic", **kwargs):
|
||||
# framework="deerflow" tells you which config dir to use
|
||||
...
|
||||
```
|
||||
|
||||
## Configuration Reference
|
||||
|
||||
```yaml
|
||||
guardrails:
|
||||
# Enable/disable guardrail middleware (default: false)
|
||||
enabled: true
|
||||
|
||||
# Block tool calls if provider raises an exception (default: true)
|
||||
fail_closed: true
|
||||
|
||||
# Passport reference -- passed as request.agent_id to the provider.
|
||||
# File path, hosted agent ID, or null (provider resolves from its config).
|
||||
passport: null
|
||||
|
||||
# Provider: loaded by class path via resolve_variable
|
||||
provider:
|
||||
use: deerflow.guardrails.builtin:AllowlistProvider
|
||||
config: # optional kwargs passed to provider.__init__
|
||||
denied_tools: ["bash"]
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
uv run python -m pytest tests/test_guardrail_middleware.py -v
|
||||
```
|
||||
|
||||
25 tests covering:
|
||||
- AllowlistProvider: allow, deny, both allowlist+denylist, async
|
||||
- GuardrailMiddleware: allow passthrough, deny with OAP codes, fail-closed, fail-open, passport forwarding, empty reasons fallback, empty tool name, protocol isinstance check
|
||||
- Async paths: awrap_tool_call for allow, deny, fail-closed, fail-open
|
||||
- GraphBubbleUp: LangGraph control signals propagate through (not caught)
|
||||
- Config: defaults, from_dict, singleton load/reset

## 1. 背景与动机
|
||||
|
||||
DeerFlow 后端当前是一个单一 Python 包（`src.*`），包含了从底层 agent 编排到上层用户产品的所有代码。随着项目发展，这种结构带来了几个问题：
|
||||
|
||||
- **复用困难**：其他产品（CLI 工具、Slack bot、第三方集成）想用 agent 能力，必须依赖整个后端，包括 FastAPI、IM SDK 等不需要的依赖
|
||||
- **职责模糊**：agent 编排逻辑和用户产品逻辑混在同一个 `src/` 下，边界不清晰
|
||||
- **依赖膨胀**：LangGraph Server 运行时不需要 FastAPI/uvicorn/Slack SDK，但当前必须安装全部依赖
|
||||
|
||||
本文档提出将后端拆分为两部分：**deerflow-harness**（可发布的 agent 框架包）和 **app**（不打包的用户产品代码）。
|
||||
|
||||
## 2. 核心概念
|
||||
|
||||
### 2.1 Harness（线束/框架层）
|
||||
|
||||
Harness 是 agent 的构建与编排框架，回答 **"如何构建和运行 agent"** 的问题：
|
||||
|
||||
- Agent 工厂与生命周期管理
|
||||
- Middleware pipeline
|
||||
- 工具系统（内置工具 + MCP + 社区工具）
|
||||
- 沙箱执行环境
|
||||
- 子 agent 委派
|
||||
- 记忆系统
|
||||
- 技能加载与注入
|
||||
- 模型工厂
|
||||
- 配置系统
|
||||
|
||||
**Harness 是一个可发布的 Python 包**（`deerflow-harness`），可以独立安装和使用。
|
||||
|
||||
**Harness 的设计原则**：对上层应用完全无感知。它不知道也不关心谁在调用它——可以是 Web App、CLI、Slack Bot、或者一个单元测试。
|
||||
|
||||
### 2.2 App（应用层）
|
||||
|
||||
App 是面向用户的产品代码，回答 **"如何将 agent 呈现给用户"** 的问题：
|
||||
|
||||
- Gateway API（FastAPI REST 接口）
|
||||
- IM Channels（飞书、Slack、Telegram 集成）
|
||||
- Custom Agent 的 CRUD 管理
|
||||
- 文件上传/下载的 HTTP 接口
|
||||
|
||||
**App 不打包、不发布**，它是 DeerFlow 项目内部的应用代码，直接运行。
|
||||
|
||||
**App 依赖 Harness，但 Harness 不依赖 App。**
|
||||
|
||||
### 2.3 边界划分
|
||||
|
||||
| 模块 | 归属 | 说明 |
|
||||
|------|------|------|
|
||||
| `config/` | Harness | 配置系统是基础设施 |
|
||||
| `reflection/` | Harness | 动态模块加载工具 |
|
||||
| `utils/` | Harness | 通用工具函数 |
|
||||
| `agents/` | Harness | Agent 工厂、middleware、state、memory |
|
||||
| `subagents/` | Harness | 子 agent 委派系统 |
|
||||
| `sandbox/` | Harness | 沙箱执行环境 |
|
||||
| `tools/` | Harness | 工具注册与发现 |
|
||||
| `mcp/` | Harness | MCP 协议集成 |
|
||||
| `skills/` | Harness | 技能加载、解析、定义 schema |
|
||||
| `models/` | Harness | LLM 模型工厂 |
|
||||
| `community/` | Harness | 社区工具（tavily、jina 等） |
|
||||
| `client.py` | Harness | 嵌入式 Python 客户端 |
|
||||
| `gateway/` | App | FastAPI REST API |
|
||||
| `channels/` | App | IM 平台集成 |
|
||||
|
||||
**关于 Custom Agents**：agent 定义格式（`config.yaml` + `SOUL.md` schema）由 Harness 层的 `config/agents_config.py` 定义，但文件的存储、CRUD、发现机制由 App 层的 `gateway/routers/agents.py` 负责。
|
||||
|
||||

|
||||
|
||||
### 3.2 Import 规则
|
||||
|
||||
两个层使用不同的 import 前缀，职责边界一目了然：
|
||||
|
||||
```python
|
||||
# ---------------------------------------------------------------
|
||||
# Harness 内部互相引用（deerflow.* 前缀）
|
||||
# ---------------------------------------------------------------
|
||||
from deerflow.agents import make_lead_agent
|
||||
from deerflow.models import create_chat_model
|
||||
from deerflow.config import get_app_config
|
||||
from deerflow.tools import get_available_tools
|
||||
|
||||
# ---------------------------------------------------------------
|
||||
# App 内部互相引用（app.* 前缀）
|
||||
# ---------------------------------------------------------------
|
||||
from app.gateway.app import app
|
||||
from app.gateway.routers.uploads import upload_files
|
||||
from app.channels.service import start_channel_service
|
||||
|
||||
# ---------------------------------------------------------------
|
||||
# App 调用 Harness（单向依赖，Harness 永远不 import app）
|
||||
# ---------------------------------------------------------------
|
||||
from deerflow.agents import make_lead_agent
|
||||
from deerflow.models import create_chat_model
|
||||
from deerflow.skills import load_skills
|
||||
from deerflow.config.extensions_config import get_extensions_config
|
||||
```
|
||||
|
||||
**App 调用 Harness 示例 — Gateway 中启动 agent**：
|
||||
|
||||
```python
|
||||
# app/gateway/routers/chat.py
|
||||
from deerflow.agents.lead_agent.agent import make_lead_agent
|
||||
from deerflow.models import create_chat_model
|
||||
from deerflow.config import get_app_config
|
||||
|
||||
async def create_chat_session(thread_id: str, model_name: str):
|
||||
config = get_app_config()
|
||||
model = create_chat_model(name=model_name)
|
||||
agent = make_lead_agent(config=...)
|
||||
# ... 使用 agent 处理用户消息
|
||||
```
|
||||
|
||||
**App 调用 Harness 示例 — Channel 中查询 skills**：
|
||||
|
||||
```python
|
||||
# app/channels/manager.py
|
||||
from deerflow.skills import load_skills
|
||||
from deerflow.agents.memory.updater import get_memory_data
|
||||
|
||||
def handle_status_command():
|
||||
skills = load_skills(enabled_only=True)
|
||||
memory = get_memory_data()
|
||||
return f"Skills: {len(skills)}, Memory facts: {len(memory.get('facts', []))}"
|
||||
```
|
||||
|
||||
**禁止方向**：Harness 代码中绝不能出现 `from app.` 或 `import app.`。
|
||||
|
||||
### 3.3 为什么 App 不打包
|
||||
|
||||
| 方面 | 打包（放 packages/ 下） | 不打包（放 backend/app/） |
|
||||
|------|------------------------|--------------------------|
|
||||
| 命名空间 | 需要 pkgutil `extend_path` 合并，或独立前缀 | 天然独立，`app.*` vs `deerflow.*` |
|
||||
| 发布需求 | 没有——App 是项目内部代码 | 不需要 pyproject.toml |
|
||||
| 复杂度 | 需要管理两个包的构建、版本、依赖声明 | 直接运行，零额外配置 |
|
||||
| 运行方式 | `pip install deerflow-app` | `PYTHONPATH=. uvicorn app.gateway.app:app` |
|
||||
|
||||
App 的唯一消费者是 DeerFlow 项目自身，没有独立发布的需求。放在 `backend/app/` 下作为普通 Python 包，通过 `PYTHONPATH` 或 editable install 让 Python 找到即可。
|
||||
|
||||
### 3.4 依赖关系
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────┐
|
||||
│ app/ (不打包，直接运行) │
|
||||
│ ├── fastapi, uvicorn │
|
||||
│ ├── slack-sdk, lark-oapi, ... │
|
||||
│ └── import deerflow.* │
|
||||
└──────────────┬──────────────────────┘
|
||||
│
|
||||
▼
|
||||
┌─────────────────────────────────────┐
|
||||
│ deerflow-harness (可发布的包) │
|
||||
│ ├── langgraph, langchain │
|
||||
│ ├── markitdown, pydantic, ... │
|
||||
│ └── 零 app 依赖 │
|
||||
└─────────────────────────────────────┘
|
||||
```
|
||||
|
||||
**依赖分类**：
|
||||
|
||||
| 分类 | 依赖包 |
|
||||
|------|--------|
|
||||
| Harness only | agent-sandbox, langchain*, langgraph*, markdownify, markitdown, pydantic, pyyaml, readabilipy, tavily-python, firecrawl-py, tiktoken, ddgs, duckdb, httpx, kubernetes, dotenv |
|
||||
| App only | fastapi, uvicorn, sse-starlette, python-multipart, lark-oapi, slack-sdk, python-telegram-bot, markdown-to-mrkdwn |
|
||||
| Shared | langgraph-sdk（channels 用 HTTP client）, pydantic, httpx |
|
||||
|
||||
### 3.5 Workspace 配置
|
||||
|
||||
`backend/pyproject.toml`（workspace root）：
|
||||
|
||||
```toml
|
||||
[project]
|
||||
name = "deer-flow"
|
||||
version = "0.1.0"
|
||||
requires-python = ">=3.12"
|
||||
dependencies = ["deerflow-harness"]
|
||||
|
||||
[dependency-groups]
|
||||
dev = ["pytest>=8.0.0", "ruff>=0.14.11"]
|
||||
# App 的额外依赖（fastapi 等）也声明在 workspace root，因为 app 不打包
|
||||
app = ["fastapi", "uvicorn", "sse-starlette", "python-multipart"]
|
||||
channels = ["lark-oapi", "slack-sdk", "python-telegram-bot"]
|
||||
|
||||
[tool.uv.workspace]
|
||||
members = ["packages/harness"]
|
||||
|
||||
[tool.uv.sources]
|
||||
deerflow-harness = { workspace = true }
|
||||
```
|
||||
|
||||
## 4. 当前的跨层依赖问题
|
||||
|
||||
在拆分之前，需要先解决 `client.py` 中两处从 harness 到 app 的反向依赖：
|
||||
|
||||
### 4.1 `_validate_skill_frontmatter`
|
||||
|
||||
```python
|
||||
# client.py — harness 导入了 app 层代码
|
||||
from src.gateway.routers.skills import _validate_skill_frontmatter
|
||||
```
|
||||
|
||||
**解决方案**：将该函数提取到 `deerflow/skills/validation.py`。这是一个纯逻辑函数（解析 YAML frontmatter、校验字段），与 FastAPI 无关。
|
||||
|
||||
### 4.2 `CONVERTIBLE_EXTENSIONS` + `convert_file_to_markdown`
|
||||
|
||||
```python
|
||||
# client.py — harness 导入了 app 层代码
|
||||
from src.gateway.routers.uploads import CONVERTIBLE_EXTENSIONS, convert_file_to_markdown
|
||||
```
|
||||
|
||||
**解决方案**：将它们提取到 `deerflow/utils/file_conversion.py`。仅依赖 `markitdown` + `pathlib`，是通用工具函数。
|
||||
|
||||
## 5. 基础设施变更
|
||||
|
||||
### 5.1 LangGraph Server
|
||||
|
||||
LangGraph Server 只需要 harness 包。`langgraph.json` 更新：
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": ["./packages/harness"],
|
||||
"graphs": {
|
||||
"lead_agent": "deerflow.agents:make_lead_agent"
|
||||
},
|
||||
"checkpointer": {
|
||||
"path": "./packages/harness/deerflow/agents/checkpointer/async_provider.py:make_checkpointer"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5.2 Gateway API
|
||||
|
||||
```bash
|
||||
# serve.sh / Makefile
|
||||
# PYTHONPATH 包含 backend/ 根目录，使 app.* 和 deerflow.* 都能被找到
|
||||
PYTHONPATH=. uvicorn app.gateway.app:app --host 0.0.0.0 --port 8001
|
||||
```
|
||||
|
||||
### 5.3 Nginx
|
||||
|
||||
无需变更（只做 URL 路由，不涉及 Python 模块路径）。
|
||||
|
||||
### 5.4 Docker
|
||||
|
||||
Dockerfile 中的 module 引用从 `src.` 改为 `deerflow.` / `app.`，`COPY` 命令需覆盖 `packages/` 和 `app/` 目录。
|
||||
|
||||
## 6. 实施计划
|
||||
|
||||
分 3 个 PR 递进执行：
|
||||
|
||||
### PR 1：提取共享工具函数（Low Risk）
|
||||
|
||||
1. 创建 `src/skills/validation.py`，从 `gateway/routers/skills.py` 提取 `_validate_skill_frontmatter`
|
||||
2. 创建 `src/utils/file_conversion.py`，从 `gateway/routers/uploads.py` 提取文件转换逻辑
|
||||
3. 更新 `client.py`、`gateway/routers/skills.py`、`gateway/routers/uploads.py` 的 import
|
||||
4. 运行全部测试确认无回归
|
||||
|
||||
### PR 2：Rename + 物理拆分（High Risk，原子操作）
|
||||
|
||||
1. 创建 `packages/harness/` 目录，创建 `pyproject.toml`
|
||||
2. `git mv` 将 harness 相关模块从 `src/` 移入 `packages/harness/deerflow/`
|
||||
3. `git mv` 将 app 相关模块从 `src/` 移入 `app/`
|
||||
4. 全局替换 import：
|
||||
- harness 模块：`src.*` → `deerflow.*`（所有 `.py` 文件、`langgraph.json`、测试、文档）
|
||||
- app 模块：`src.gateway.*` → `app.gateway.*`、`src.channels.*` → `app.channels.*`
|
||||
5. 更新 workspace root `pyproject.toml`
|
||||
6. 更新 `langgraph.json`、`Makefile`、`Dockerfile`
|
||||
7. `uv sync` + 全部测试 + 手动验证服务启动
|
||||
|
||||
### PR 3：边界检查 + 文档（Low Risk）
|
||||
|
||||
1. 添加 lint 规则：检查 harness 不 import app 模块
|
||||
2. 更新 `CLAUDE.md`、`README.md`
|
||||
|
||||
## 7. 风险与缓解
|
||||
|
||||
| 风险 | 影响 | 缓解措施 |
|
||||
|------|------|----------|
|
||||
| 全局 rename 误伤 | 字符串中的 `src` 被错误替换 | 正则精确匹配 `\bsrc\.`，review diff |
|
||||
| LangGraph Server 找不到模块 | 服务启动失败 | `langgraph.json` 的 `dependencies` 指向正确的 harness 包路径 |
|
||||
| App 的 `PYTHONPATH` 缺失 | Gateway/Channel 启动 import 报错 | Makefile/Docker 统一设置 `PYTHONPATH=.` |
|
||||
| `config.yaml` 中的 `use` 字段引用旧路径 | 运行时模块解析失败 | `config.yaml` 中的 `use` 字段同步更新为 `deerflow.*` |
|
||||
| 测试中 `sys.path` 混乱 | 测试失败 | 用 editable install（`uv sync`）确保 deerflow 可导入，`conftest.py` 中添加 `app/` 到 `sys.path` |
|
||||
|
||||
## 8. 未来演进
|
||||
|
||||
- **独立发布**：harness 可以发布到内部 PyPI，让其他项目直接 `pip install deerflow-harness`
|
||||
- **插件化 App**：不同的 app（web、CLI、bot）可以各自独立，都依赖同一个 harness
|
||||
- **更细粒度拆分**：如果 harness 内部模块继续增长，可以进一步拆分（如 `deerflow-sandbox`、`deerflow-mcp`）

# Memory System Improvements
|
||||
|
||||
This document tracks memory injection behavior and roadmap status.
|
||||
This document describes recent improvements to the memory system's fact injection mechanism.
|
||||
|
||||
## Status (As Of 2026-03-10)
|
||||
## Overview
|
||||
|
||||
Implemented in `main`:
|
||||
- Accurate token counting via `tiktoken` in `format_memory_for_injection`.
|
||||
- Facts are injected into prompt memory context.
|
||||
- Facts are ranked by confidence (descending).
|
||||
- Injection respects `max_injection_tokens` budget.
|
||||
Two major improvements have been made to the `format_memory_for_injection` function:
|
||||
|
||||
Planned / not yet merged:
|
||||
- TF-IDF similarity-based fact retrieval.
|
||||
- `current_context` input for context-aware scoring.
|
||||
- Configurable similarity/confidence weights (`similarity_weight`, `confidence_weight`).
|
||||
- Middleware/runtime wiring for context-aware retrieval before each model call.
|
||||
1. **Similarity-Based Fact Retrieval**: Uses TF-IDF to select facts most relevant to current conversation context
|
||||
2. **Accurate Token Counting**: Uses tiktoken for precise token estimation instead of rough character-based approximation
|
||||
|
||||
## Current Behavior
|
||||
## 1. Similarity-Based Fact Retrieval
|
||||
|
||||
Function today:
|
||||
### Problem
|
||||
The original implementation selected facts based solely on confidence scores, taking the top 15 highest-confidence facts regardless of their relevance to the current conversation. This could result in injecting irrelevant facts while omitting contextually important ones.
|
||||
|
||||
### Solution
|
||||
The new implementation uses **TF-IDF (Term Frequency-Inverse Document Frequency)** vectorization with cosine similarity to measure how relevant each fact is to the current conversation context.
|
||||
|
||||
**Scoring Formula**:
|
||||
```
|
||||
final_score = (similarity × 0.6) + (confidence × 0.4)
|
||||
```
|
||||
|
||||
- **Similarity (60% weight)**: Cosine similarity between fact content and current context
|
||||
- **Confidence (40% weight)**: LLM-assigned confidence score (0-1)
|
||||
|
||||
### Benefits
|
||||
- **Context-Aware**: Prioritizes facts relevant to what the user is currently discussing
|
||||
- **Dynamic**: Different facts surface based on conversation topic
|
||||
- **Balanced**: Considers both relevance and reliability
|
||||
- **Fallback**: Gracefully degrades to confidence-only ranking if context is unavailable
|
||||
|
||||
### Example
|
||||
Given facts about Python, React, and Docker:
|
||||
- User asks: *"How should I write Python tests?"*
|
||||
- Prioritizes: Python testing, type hints, pytest
|
||||
- User asks: *"How to optimize my Next.js app?"*
|
||||
- Prioritizes: React/Next.js experience, performance optimization
|
||||
|
||||
### Configuration
|
||||
Customize weights in `config.yaml` (optional):
|
||||
```yaml
|
||||
memory:
|
||||
similarity_weight: 0.6 # Weight for TF-IDF similarity (0-1)
|
||||
confidence_weight: 0.4 # Weight for confidence score (0-1)
|
||||
```
|
||||
|
||||
**Note**: Weights should sum to 1.0 for best results.
|
||||
|
||||
## 2. Accurate Token Counting
|
||||
|
||||
### Problem
|
||||
The original implementation estimated tokens using a simple formula:
|
||||
```python
|
||||
max_chars = max_tokens * 4
|
||||
```
|
||||
|
||||
This assumes ~4 characters per token, which is:
|
||||
- Inaccurate for many languages and content types
|
||||
- Can lead to over-injection (exceeding token limits)
|
||||
- Can lead to under-injection (wasting available budget)
|
||||
|
||||
### Solution
|
||||
The new implementation uses **tiktoken**, OpenAI's official tokenizer library, to count tokens accurately:
|
||||
|
||||
```python
|
||||
def format_memory_for_injection(memory_data: dict[str, Any], max_tokens: int = 2000) -> str:
|
||||
import tiktoken
|
||||
|
||||
def _count_tokens(text: str, encoding_name: str = "cl100k_base") -> int:
|
||||
encoding = tiktoken.get_encoding(encoding_name)
|
||||
return len(encoding.encode(text))
|
||||
```
|
||||
|
||||
Current injection format:
|
||||
- `User Context` section from `user.*.summary`
|
||||
- `History` section from `history.*.summary`
|
||||
- `Facts` section from `facts[]`, sorted by confidence, appended until token budget is reached
|
||||
- Uses `cl100k_base` encoding (GPT-4, GPT-3.5, text-embedding-ada-002)
|
||||
- Provides exact token counts for budget management
|
||||
- Falls back to character-based estimation if tiktoken fails
|
||||
|
||||
Token counting:
|
||||
- Uses `tiktoken` (`cl100k_base`) when available
|
||||
- Falls back to `len(text) // 4` if tokenizer import fails
|
||||
### Benefits
|
||||
- **Precision**: Exact token counts match what the model sees
|
||||
- **Budget Optimization**: Maximizes use of available token budget
|
||||
- **No Overflows**: Prevents exceeding `max_injection_tokens` limit
|
||||
- **Better Planning**: Each section's token cost is known precisely
|
||||
|
||||
## Known Gap
|
||||
### Example
|
||||
```python
|
||||
text = "This is a test string to count tokens accurately using tiktoken."
|
||||
|
||||
Previous versions of this document described TF-IDF/context-aware retrieval as if it were already shipped.
|
||||
That was not accurate for `main` and caused confusion.
|
||||
# Old method
|
||||
char_count = len(text) # 64 characters
|
||||
old_estimate = char_count // 4 # 16 tokens (overestimate)
|
||||
|
||||
Issue reference: `#1059`
|
||||
|
||||
## Roadmap (Planned)
|
||||
|
||||
Planned scoring strategy:
|
||||
|
||||
```text
|
||||
final_score = (similarity * 0.6) + (confidence * 0.4)
|
||||
# New method
|
||||
accurate_count = _count_tokens(text) # 13 tokens (exact)
|
||||
```
|
||||
|
||||
Planned integration shape:
|
||||
1. Extract recent conversational context from filtered user/final-assistant turns.
|
||||
2. Compute TF-IDF cosine similarity between each fact and current context.
|
||||
3. Rank by weighted score and inject under token budget.
|
||||
4. Fall back to confidence-only ranking if context is unavailable.
|
||||
**Result**: 3-token difference (18.75% error rate)
|
||||
|
||||
## Validation
|
||||
In production, errors can be much larger for:
|
||||
- Code snippets (more tokens per character)
|
||||
- Non-English text (variable token ratios)
|
||||
- Technical jargon (often multi-token words)
|
||||
|
||||
Current regression coverage includes:
|
||||
- facts inclusion in memory injection output
|
||||
- confidence ordering
|
||||
- token-budget-limited fact inclusion
|
||||
## Implementation Details
|
||||
|
||||
Tests:
|
||||
- `backend/tests/test_memory_prompt_injection.py`
|
||||
### Function Signature
|
||||
```python
|
||||
def format_memory_for_injection(
|
||||
memory_data: dict[str, Any],
|
||||
max_tokens: int = 2000,
|
||||
current_context: str | None = None,
|
||||
) -> str:
|
||||
```
|
||||
|
||||
**New Parameter**:
|
||||
- `current_context`: Optional string containing recent conversation messages for similarity calculation
|
||||
|
||||
### Backward Compatibility
|
||||
The function remains **100% backward compatible**:
|
||||
- If `current_context` is `None` or empty, falls back to confidence-only ranking
|
||||
- Existing callers without the parameter work exactly as before
|
||||
- Token counting is always accurate (transparent improvement)
|
||||
|
||||
### Integration Point
|
||||
Memory is **dynamically injected** via `MemoryMiddleware.before_model()`:
|
||||
|
||||
```python
|
||||
# src/agents/middlewares/memory_middleware.py
|
||||
|
||||
def _extract_conversation_context(messages: list, max_turns: int = 3) -> str:
|
||||
"""Extract recent conversation (user input + final responses only)."""
|
||||
context_parts = []
|
||||
turn_count = 0
|
||||
|
||||
for msg in reversed(messages):
|
||||
if msg.type == "human":
|
||||
# Always include user messages
|
||||
context_parts.append(extract_text(msg))
|
||||
turn_count += 1
|
||||
if turn_count >= max_turns:
|
||||
break
|
||||
|
||||
elif msg.type == "ai" and not msg.tool_calls:
|
||||
# Only include final AI responses (no tool_calls)
|
||||
context_parts.append(extract_text(msg))
|
||||
|
||||
# Skip tool messages and AI messages with tool_calls
|
||||
|
||||
return " ".join(reversed(context_parts))
|
||||
|
||||
|
||||
class MemoryMiddleware:
|
||||
def before_model(self, state, runtime):
|
||||
"""Inject memory before EACH LLM call (not just before_agent)."""
|
||||
|
||||
# Get recent conversation context (filtered)
|
||||
conversation_context = _extract_conversation_context(
|
||||
state["messages"],
|
||||
max_turns=3
|
||||
)
|
||||
|
||||
# Load memory with context-aware fact selection
|
||||
memory_data = get_memory_data()
|
||||
memory_content = format_memory_for_injection(
|
||||
memory_data,
|
||||
max_tokens=config.max_injection_tokens,
|
||||
current_context=conversation_context, # ✅ Clean conversation only
|
||||
)
|
||||
|
||||
# Inject as system message
|
||||
memory_message = SystemMessage(
|
||||
content=f"<memory>\n{memory_content}\n</memory>",
|
||||
name="memory_context",
|
||||
)
|
||||
|
||||
return {"messages": [memory_message] + state["messages"]}
|
||||
```
|
||||
|
||||
### How It Works
|
||||
|
||||
1. **User continues conversation**:
|
||||
```
|
||||
Turn 1: "I'm working on a Python project"
|
||||
Turn 2: "It uses FastAPI and SQLAlchemy"
|
||||
Turn 3: "How do I write tests?" ← Current query
|
||||
```
|
||||
|
||||
2. **Extract recent context**: Last 3 turns combined:
|
||||
```
|
||||
"I'm working on a Python project. It uses FastAPI and SQLAlchemy. How do I write tests?"
|
||||
```
|
||||
|
||||
3. **TF-IDF scoring**: Ranks facts by relevance to this context
|
||||
- High score: "Prefers pytest for testing" (testing + Python)
|
||||
- High score: "Likes type hints in Python" (Python related)
|
||||
- High score: "Expert in Python and FastAPI" (Python + FastAPI)
|
||||
- Low score: "Uses Docker for containerization" (less relevant)
|
||||
|
||||
4. **Injection**: Top-ranked facts injected into system prompt's `<memory>` section
|
||||
|
||||
5. **Agent sees**: Full system prompt with relevant memory context
|
||||
|
||||
### Benefits of Dynamic System Prompt
|
||||
|
||||
- **Multi-Turn Context**: Uses last 3 turns, not just current question
|
||||
- Captures ongoing conversation flow
|
||||
- Better understanding of user's current focus
|
||||
- **Query-Specific Facts**: Different facts surface based on conversation topic
|
||||
- **Clean Architecture**: No middleware message manipulation
|
||||
- **LangChain Native**: Uses built-in dynamic system prompt support
|
||||
- **Runtime Flexibility**: Memory regenerated for each agent invocation
|
||||
|
||||
## Dependencies
|
||||
|
||||
New dependencies added to `pyproject.toml`:
|
||||
```toml
|
||||
dependencies = [
|
||||
# ... existing dependencies ...
|
||||
"tiktoken>=0.8.0", # Accurate token counting
|
||||
"scikit-learn>=1.6.1", # TF-IDF vectorization
|
||||
]
|
||||
```
|
||||
|
||||
Install with:
|
||||
```bash
|
||||
cd backend
|
||||
uv sync
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
Run the test script to verify improvements:
|
||||
```bash
|
||||
cd backend
|
||||
python test_memory_improvement.py
|
||||
```
|
||||
|
||||
Expected output shows:
|
||||
- Different fact ordering based on context
|
||||
- Accurate token counts vs old estimates
|
||||
- Budget-respecting fact selection
|
||||
|
||||
## Performance Impact
|
||||
|
||||
### Computational Cost
|
||||
- **TF-IDF Calculation**: O(n × m) where n=facts, m=vocabulary
|
||||
- Negligible for typical fact counts (10-100 facts)
|
||||
- Caching opportunities if context doesn't change
|
||||
- **Token Counting**: ~10-100µs per call
|
||||
- Faster than the old character-counting approach
|
||||
- Minimal overhead compared to LLM inference
|
||||
|
||||
### Memory Usage
|
||||
- **TF-IDF Vectorizer**: ~1-5MB for typical vocabulary
|
||||
- Instantiated once per injection call
|
||||
- Garbage collected after use
|
||||
- **Tiktoken Encoding**: ~1MB (cached singleton)
|
||||
- Loaded once per process lifetime
|
||||
|
||||
### Recommendations
|
||||
- Current implementation is optimized for accuracy over caching
|
||||
- For high-throughput scenarios, consider:
|
||||
- Pre-computing fact embeddings (store in memory.json)
|
||||
- Caching TF-IDF vectorizer between calls
|
||||
- Using approximate nearest neighbor search for >1000 facts
|
||||
|
||||
## Summary
|
||||
|
||||
| Aspect | Before | After |
|
||||
|--------|--------|-------|
|
||||
| Fact Selection | Top 15 by confidence only | Relevance-based (similarity + confidence) |
|
||||
| Token Counting | `len(text) // 4` | `tiktoken.encode(text)` |
|
||||
| Context Awareness | None | TF-IDF cosine similarity |
|
||||
| Accuracy | ±25% token estimate | Exact token count |
|
||||
| Configuration | Fixed weights | Customizable similarity/confidence weights |
|
||||
|
||||
These improvements result in:
|
||||
- **More relevant** facts injected into context
|
||||
- **Better utilization** of available token budget
|
||||
- **Fewer hallucinations** due to focused context
|
||||
- **Higher quality** agent responses

# Memory System Improvements - Summary
|
||||
|
||||
## Sync Note (2026-03-10)
|
||||
## 改进概述
|
||||
|
||||
This summary is synchronized with the `main` branch implementation.
|
||||
TF-IDF/context-aware retrieval is **planned**, not merged yet.
|
||||
针对你提出的两个问题进行了优化：
|
||||
1. ✅ **粗糙的 token 计算**（`字符数 * 4`）→ 使用 tiktoken 精确计算
|
||||
2. ✅ **缺乏相似度召回** → 使用 TF-IDF + 最近对话上下文
|
||||
|
||||
## Implemented
|
||||
## 核心改进
|
||||
|
||||
- Accurate token counting with `tiktoken` in memory injection.
|
||||
- Facts are injected into `<memory>` prompt content.
|
||||
- Facts are ordered by confidence and bounded by `max_injection_tokens`.
|
||||
### 1. 基于对话上下文的智能 Facts 召回
|
||||
|
||||
## Planned (Not Yet Merged)
|
||||
**之前**：
|
||||
- 只按 confidence 排序取前 15 个
|
||||
- 无论用户在讨论什么都注入相同的 facts
|
||||
|
||||
- TF-IDF cosine similarity recall based on recent conversation context.
|
||||
- `current_context` parameter for `format_memory_for_injection`.
|
||||
- Weighted ranking (`similarity` + `confidence`).
|
||||
- Runtime extraction/injection flow for context-aware fact selection.
|
||||
**现在**：
|
||||
- 提取最近 **3 轮对话**（human + AI 消息）作为上下文
|
||||
- 使用 **TF-IDF 余弦相似度**计算每个 fact 与对话的相关性
|
||||
- 综合评分：`相似度(60%) + 置信度(40%)`
|
||||
- 动态选择最相关的 facts
|
||||
|
||||
## Why This Sync Was Needed
|
||||
**示例**：
|
||||
```
|
||||
对话历史：
|
||||
Turn 1: "我在做一个 Python 项目"
|
||||
Turn 2: "使用 FastAPI 和 SQLAlchemy"
|
||||
Turn 3: "怎么写测试？"
|
||||
|
||||
Earlier docs described TF-IDF behavior as already implemented, which did not match code in `main`.
|
||||
This mismatch is tracked in issue `#1059`.
|
||||
上下文: "我在做一个 Python 项目 使用 FastAPI 和 SQLAlchemy 怎么写测试？"
|
||||
|
||||
## Current API Shape
|
||||
相关度高的 facts:
|
||||
✓ "Prefers pytest for testing" (Python + 测试)
|
||||
✓ "Expert in Python and FastAPI" (Python + FastAPI)
|
||||
✓ "Likes type hints in Python" (Python)
|
||||
|
||||
```python
|
||||
def format_memory_for_injection(memory_data: dict[str, Any], max_tokens: int = 2000) -> str:
|
||||
相关度低的 facts:
|
||||
✗ "Uses Docker for containerization" (不相关)
|
||||
```
|
||||
|
||||
No `current_context` argument is currently available in `main`.
|
||||
### 2. 精确的 Token 计算
|
||||
|
||||
## Verification Pointers
|
||||
**之前**：
|
||||
```python
|
||||
max_chars = max_tokens * 4 # 粗糙估算
|
||||
```
|
||||
|
||||
- Implementation: `packages/harness/deerflow/agents/memory/prompt.py`
|
||||
- Prompt assembly: `packages/harness/deerflow/agents/lead_agent/prompt.py`
|
||||
- Regression tests: `backend/tests/test_memory_prompt_injection.py`
|
||||
**现在**：
|
||||
```python
|
||||
import tiktoken
|
||||
|
||||
def _count_tokens(text: str) -> int:
|
||||
encoding = tiktoken.get_encoding("cl100k_base") # GPT-4/3.5
|
||||
return len(encoding.encode(text))
|
||||
```
|
||||
|
||||
**效果对比**：
|
||||
```python
|
||||
text = "This is a test string to count tokens accurately."
|
||||
旧方法: len(text) // 4 = 12 tokens (估算)
|
||||
新方法: tiktoken.encode = 10 tokens (精确)
|
||||
误差: 20%
|
||||
```
|
||||
|
||||
### 3. 多轮对话上下文
|
||||
|
||||
**之前的担心**：
|
||||
> "只传最近一条 human message 会不会上下文不太够？"
|
||||
|
||||
**现在的解决方案**：
|
||||
- 提取最近 **3 轮对话**（可配置）
|
||||
- 包括 human 和 AI 消息
|
||||
- 更完整的对话上下文
|
||||
|
||||
**示例**：
|
||||
```
|
||||
单条消息: "怎么写测试？"
|
||||
→ 缺少上下文，不知道是什么项目
|
||||
|
||||
3轮对话: "Python 项目 + FastAPI + 怎么写测试？"
|
||||
→ 完整上下文，能选择更相关的 facts
|
||||
```
|
||||
|
||||
## 实现方式
|
||||
|
||||
### Middleware 动态注入
|
||||
|
||||
使用 `before_model` 钩子在**每次 LLM 调用前**注入 memory：
|
||||
|
||||
```python
|
||||
# src/agents/middlewares/memory_middleware.py
|
||||
|
||||
def _extract_conversation_context(messages: list, max_turns: int = 3) -> str:
|
||||
"""提取最近 3 轮对话（只包含用户输入和最终回复）"""
|
||||
context_parts = []
|
||||
turn_count = 0
|
||||
|
||||
for msg in reversed(messages):
|
||||
msg_type = getattr(msg, "type", None)
|
||||
|
||||
if msg_type == "human":
|
||||
# ✅ 总是包含用户消息
|
||||
content = extract_text(msg)
|
||||
if content:
|
||||
context_parts.append(content)
|
||||
turn_count += 1
|
||||
if turn_count >= max_turns:
|
||||
break
|
||||
|
||||
elif msg_type == "ai":
|
||||
# ✅ 只包含没有 tool_calls 的 AI 消息（最终回复）
|
||||
tool_calls = getattr(msg, "tool_calls", None)
|
||||
if not tool_calls:
|
||||
content = extract_text(msg)
|
||||
if content:
|
||||
context_parts.append(content)
|
||||
|
||||
# ✅ 跳过 tool messages 和带 tool_calls 的 AI 消息
|
||||
|
||||
return " ".join(reversed(context_parts))
|
||||
|
||||
|
||||
class MemoryMiddleware:
|
||||
def before_model(self, state, runtime):
|
||||
"""在每次 LLM 调用前注入 memory（不是 before_agent）"""
|
||||
|
||||
# 1. 提取最近 3 轮对话（过滤掉 tool calls）
|
||||
messages = state["messages"]
|
||||
conversation_context = _extract_conversation_context(messages, max_turns=3)
|
||||
|
||||
# 2. 使用干净的对话上下文选择相关 facts
|
||||
memory_data = get_memory_data()
|
||||
memory_content = format_memory_for_injection(
|
||||
memory_data,
|
||||
max_tokens=config.max_injection_tokens,
|
||||
current_context=conversation_context, # ✅ 只包含真实对话内容
|
||||
)
|
||||
|
||||
# 3. 作为 system message 注入到消息列表开头
|
||||
memory_message = SystemMessage(
|
||||
content=f"<memory>\n{memory_content}\n</memory>",
|
||||
name="memory_context", # 用于去重检测
|
||||
)
|
||||
|
||||
# 4. 插入到消息列表开头
|
||||
updated_messages = [memory_message] + messages
|
||||
return {"messages": updated_messages}
|
||||
```
|
||||
|
||||
### 为什么这样设计？
|
||||
|
||||
基于你的三个重要观察：
|
||||
|
||||
1. **应该用 `before_model` 而不是 `before_agent`**
|
||||
- ✅ `before_agent`: 只在整个 agent 开始时调用一次
|
||||
- ✅ `before_model`: 在**每次 LLM 调用前**都会调用
|
||||
- ✅ 这样每次 LLM 推理都能看到最新的相关 memory
|
||||
|
||||
2. **messages 数组里只有 human/ai/tool，没有 system**
|
||||
- ✅ 虽然不常见，但 LangChain 允许在对话中插入 system message
|
||||
- ✅ Middleware 可以修改 messages 数组
|
||||
- ✅ 使用 `name="memory_context"` 防止重复注入
|
||||
|
||||
3. **应该剔除 tool call 的 AI messages，只传用户输入和最终输出**
|
||||
- ✅ 过滤掉带 `tool_calls` 的 AI 消息（中间步骤）
|
||||
- ✅ 只保留： - Human 消息（用户输入）
|
||||
- AI 消息但无 tool_calls（最终回复）
|
||||
- ✅ 上下文更干净，TF-IDF 相似度计算更准确
|
||||
|
||||
## 配置选项
|
||||
|
||||
在 `config.yaml` 中可以调整：
|
||||
|
||||
```yaml
|
||||
memory:
|
||||
enabled: true
|
||||
max_injection_tokens: 2000 # ✅ 使用精确 token 计数
|
||||
|
||||
# 高级设置（可选）
|
||||
# max_context_turns: 3 # 对话轮数（默认 3）
|
||||
# similarity_weight: 0.6 # 相似度权重
|
||||
# confidence_weight: 0.4 # 置信度权重
|
||||
```
|
||||
|
||||
## 依赖变更
|
||||
|
||||
新增依赖：
|
||||
```toml
|
||||
dependencies = [
|
||||
"tiktoken>=0.8.0", # 精确 token 计数
|
||||
"scikit-learn>=1.6.1", # TF-IDF 向量化
|
||||
]
|
||||
```
|
||||
|
||||
安装：
|
||||
```bash
|
||||
cd backend
|
||||
uv sync
|
||||
```
|
||||
|
||||
## 性能影响
|
||||
|
||||
- **TF-IDF 计算**：O(n × m)，n=facts 数量，m=词汇表大小
|
||||
- 典型场景（10-100 facts）：< 10ms
|
||||
- **Token 计数**：~100µs per call
|
||||
- 比字符计数还快
|
||||
- **总开销**：可忽略（相比 LLM 推理）
|
||||
|
||||
## 向后兼容性
|
||||
|
||||
✅ 完全向后兼容：
|
||||
- 如果没有 `current_context`，退化为按 confidence 排序
|
||||
- 所有现有配置继续工作
|
||||
- 不影响其他功能
|
||||
|
||||
## 文件变更清单
|
||||
|
||||
1. **核心功能**
|
||||
- `src/agents/memory/prompt.py` - 添加 TF-IDF 召回和精确 token 计数
|
||||
- `src/agents/lead_agent/prompt.py` - 动态系统提示
|
||||
- `src/agents/lead_agent/agent.py` - 传入函数而非字符串
|
||||
|
||||
2. **依赖**
|
||||
- `pyproject.toml` - 添加 tiktoken 和 scikit-learn
|
||||
|
||||
3. **文档**
|
||||
- `docs/MEMORY_IMPROVEMENTS.md` - 详细技术文档
|
||||
- `docs/MEMORY_IMPROVEMENTS_SUMMARY.md` - 改进总结（本文件）
|
||||
- `CLAUDE.md` - 更新架构说明
|
||||
- `config.example.yaml` - 添加配置说明
|
||||
|
||||
## 测试验证
|
||||
|
||||
运行项目验证：
|
||||
```bash
|
||||
cd backend
|
||||
make dev
|
||||
```
|
||||
|
||||
在对话中测试：
|
||||
1. 讨论不同主题（Python、React、Docker 等）
|
||||
2. 观察不同对话注入的 facts 是否不同
|
||||
3. 检查 token 预算是否被准确控制
|
||||
|
||||
## 总结
|
||||
|
||||
| 问题 | 之前 | 现在 |
|
||||
|------|------|------|
|
||||
| Token 计算 | `len(text) // 4` (±25% 误差) | `tiktoken.encode()` (精确) |
|
||||
| Facts 选择 | 按 confidence 固定排序 | TF-IDF 相似度 + confidence |
|
||||
| 上下文 | 无 | 最近 3 轮对话 |
|
||||
| 实现方式 | 静态系统提示 | 动态系统提示函数 |
|
||||
| 配置灵活性 | 有限 | 可调轮数和权重 |
|
||||
|
||||
所有改进都实现了，并且：
|
||||
- ✅ 不修改 messages 数组
|
||||
- ✅ 使用多轮对话上下文
|
||||

# Memory Settings Review
|
||||
|
||||
Use this when reviewing the Memory Settings add/edit flow locally with the fewest possible manual steps.
|
||||
|
||||
## Quick Review
|
||||
|
||||
1. Start DeerFlow locally using any working development setup you already use.
|
||||
|
||||
Examples:
|
||||
|
||||
```bash
|
||||
make dev
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```bash
|
||||
make docker-start
|
||||
```
|
||||
|
||||
If you already have DeerFlow running locally, you can reuse that existing setup.
|
||||
|
||||
2. Load the sample memory fixture.
|
||||
|
||||
```bash
|
||||
python scripts/load_memory_sample.py
|
||||
```
|
||||
|
||||
3. Open `Settings > Memory`.
|
||||
|
||||
Default local URLs:
|
||||
- App: `http://localhost:2026`
|
||||
- Local frontend-only fallback: `http://localhost:3000`
|
||||
|
||||
## Minimal Manual Test
|
||||
|
||||
1. Click `Add fact`.
|
||||
2. Create a new fact with:
|
||||
- Content: `Reviewer-added memory fact`
|
||||
- Category: `testing`
|
||||
- Confidence: `0.88`
|
||||
3. Confirm the new fact appears immediately and shows `Manual` as the source.
|
||||
4. Edit the sample fact `This sample fact is intended for edit testing.` and change it to:

## Optional Sanity Checks
|
||||
|
||||
- Search `Reviewer-added` and confirm the new fact is matched.
|
||||
- Search `workflow` and confirm category text is searchable.
|
||||
- Switch between `All`, `Facts`, and `Summaries`.
|
||||
- Delete the disposable sample fact `Delete fact testing can target this disposable sample entry.` and confirm the list updates immediately.
|
||||
- Clear all memory and confirm the page enters the empty state.
|
||||
|
||||
## Fixture Files

|
||||
- Sample fixture: `backend/docs/memory-settings-sample.json`
|
||||
- Default local runtime target: `backend/.deer-flow/memory.json`

# DeerFlow 流式输出设计
|
||||
|
||||
本文档解释 DeerFlow 是如何把 LangGraph agent 的事件流端到端送到两类消费者（HTTP 客户端、嵌入式 Python 调用方）的：两条路径为什么**必须**并存、它们各自的契约是什么、以及设计里那些 non-obvious 的不变式。
|
||||
|
||||
---
|
||||
|
||||
## TL;DR
|
||||
|
||||
- DeerFlow 有**两条并行**的流式路径：**Gateway 路径**（async / HTTP SSE / JSON 序列化）服务浏览器和 IM 渠道；**DeerFlowClient 路径**（sync / in-process / 原生 LangChain 对象）服务 Jupyter、脚本、测试。它们**无法合并**——消费者模型不同。
|
||||
- 两条路径都从 `create_agent()` 工厂出发，核心都是订阅 LangGraph 的 `stream_mode=["values", "messages", "custom"]`。`values` 是节点级 state 快照，`messages` 是 LLM token 级 delta，`custom` 是显式 `StreamWriter` 事件。**这三种模式不是详细程度的梯度，是三个独立的事件源**，要 token 流就必须显式订阅 `messages`。
|
||||
- 嵌入式 client 为每个 `stream()` 调用维护三个 `set[str]`：`seen_ids` / `streamed_ids` / `counted_usage_ids`。三者看起来相似但管理**三个独立的不变式**，不能合并。
|
||||
|
||||
---
|
||||
|
||||
## 为什么有两条流式路径
|
||||
|
||||
两条路径服务的消费者模型根本不同：
|
||||
|
||||
| 维度 | Gateway 路径 | DeerFlowClient 路径 |
|
||||
|---|---|---|
|
||||
| 入口 | FastAPI `/runs/stream` endpoint | `DeerFlowClient.stream(message)` |
|
||||
| 触发层 | `runtime/runs/worker.py::run_agent` | `packages/harness/deerflow/client.py::DeerFlowClient.stream` |
|
||||
| 执行模型 | `async def` + `agent.astream()` | sync generator + `agent.stream()` |
|
||||
| 事件传输 | `StreamBridge`（asyncio Queue）+ `sse_consumer` | 直接 `yield` |
|
||||
| 序列化 | `serialize(chunk)` → 纯 JSON dict，匹配 LangGraph Platform wire 格式 | `StreamEvent.data`，携带原生 LangChain 对象 |
|
||||
| 消费者 | 前端 `useStream` React hook、飞书/Slack/Telegram channel、LangGraph SDK 客户端 | Jupyter notebook、集成测试、内部 Python 脚本 |
|
||||
| 生命周期管理 | `RunManager`：run_id 跟踪、disconnect 语义、multitask 策略、heartbeat | 无；函数返回即结束 |
|
||||
| 断连恢复 | `Last-Event-ID` SSE 重连 | 无需要 |
|
||||
|
||||
**两条路径的存在是 DRY 的刻意妥协**：Gateway 的全部基础设施（async + Queue + JSON + RunManager）**都是为了跨网络边界把事件送给 HTTP 消费者**。当生产者（agent）和消费者（Python 调用栈）在同一个进程时，这整套东西都是纯开销。
|
||||
|
||||
### 为什么不能让 DeerFlowClient 复用 Gateway
|
||||
|
||||
曾经考虑过三种复用方案，都被否决：
|
||||
|
||||
1. **让 `client.stream()` 变成 `async def client.astream()`**
|
||||
breaking change。用户用不上的 `async for` / `asyncio.run()` 要硬塞进 Jupyter notebook 和同步脚本。DeerFlowClient 的一大卖点（"把 agent 当普通函数调用"）直接消失。
|
||||
|
||||
2. **在 `client.stream()` 内部起一个独立事件循环线程，用 `StreamBridge` 在 sync/async 之间做桥接**
|
||||
引入线程池、队列、信号量。为了"消除重复"，把**复杂度**代替代码行数引进来。是典型的"wrong abstraction"——开销高于复用收益。
|
||||
|
||||
3. **让 `run_agent` 自己兼容 sync mode**
|
||||
给 Gateway 加一条用不到的死分支，污染 worker.py 的焦点。
|
||||
|
||||
所以两条路径的事件处理逻辑会**相似但不共享**。这是刻意设计，不是疏忽。

||||
## LangGraph `stream_mode` 三层语义
|
||||
|
||||
LangGraph 的 `agent.stream(stream_mode=[...])` 是**多路复用**接口：一次订阅多个 mode，每个 mode 是一个独立的事件源。三种核心 mode：

|

| Mode | 发射时机 | Payload | 粒度 |
|
||||
|---|---|---|---|
|
||||
| `values` | 每个 graph 节点完成后 | 完整 state dict（title、messages、artifacts）| 节点级 |
|
||||
| `messages` | LLM 每次 yield 一个 chunk；tool 节点完成时 | `(AIMessageChunk \| ToolMessage, metadata_dict)` | token 级 |
|
||||
| `custom` | 用户代码显式调用 `StreamWriter.write()` | 任意 dict | 应用定义 |
|
||||
|
||||
### 两套命名的由来
|
||||
|
||||
同一件事在**三个协议层**有三个名字：
|
||||
|
||||
```
|
||||
Application HTTP / SSE LangGraph Graph
|
||||
┌──────────────┐ ┌──────────────┐ ┌──────────────┐
|
||||
│ frontend │ │ LangGraph │ │ agent.astream│
|
||||
│ useStream │──"messages- │ Platform SDK │──"messages"──│ graph.astream│
|
||||
│ Feishu IM │ tuple"──────│ HTTP wire │ │ │
|
||||
└──────────────┘ └──────────────┘ └──────────────┘
|
||||
```
|
||||
|
||||
- **Graph 层**（`agent.stream` / `agent.astream`）：LangGraph Python 直接 API，mode 叫 **`"messages"`**。
|
||||
- **Platform SDK 层**（`langgraph-sdk` HTTP client）：跨进程 HTTP 契约，mode 叫 **`"messages-tuple"`**。
|
||||
- **Gateway worker** 显式做翻译：`if m == "messages-tuple": lg_modes.append("messages")`（`runtime/runs/worker.py:117-121`）。
|
||||
|
||||
**后果**：`DeerFlowClient.stream()` 直接调 `agent.stream()`（Graph 层），所以必须传 `"messages"`。`app/channels/manager.py` 通过 `langgraph-sdk` 走 HTTP SDK，所以传 `"messages-tuple"`。**这两个字符串不能互相替代**，也不能抽成"一个共享常量"——它们是不同协议层的 type alias，共享只会让某一层说不是它母语的话。

||||

|
||||
end
|
||||
end
|
||||
```
|
||||
|
||||
关键组件：
|
||||
|
||||
- `runtime/runs/worker.py::run_agent` — 在 `asyncio.Task` 里跑 `agent.astream()`，把每个 chunk 通过 `serialize(chunk, mode=mode)` 转成 JSON，再 `bridge.publish()`。
|
||||
- `runtime/stream_bridge` — 抽象 Queue。`publish/subscribe` 解耦生产者和消费者，支持 `Last-Event-ID` 重连、心跳、多订阅者 fan-out。
|
||||
- `app/gateway/services.py::sse_consumer` — 从 bridge 订阅，格式化为 SSE wire 帧。
|
||||
- `runtime/serialization.py::serialize` — mode-aware 序列化；`messages` mode 下 `serialize_messages_tuple` 把 `(chunk, metadata)` 转成 `[chunk.model_dump(), metadata]`。
|
||||
|
||||
**`StreamBridge` 的存在价值**：当生产者（`run_agent` 任务）和消费者（HTTP 连接）在不同的 asyncio task 里运行时，需要一个可以跨 task 传递事件的中介。Queue 同时还承担断连重连的 buffer 和多订阅者的 fan-out。
|
||||
|
||||
---
|
||||
|
||||
## DeerFlowClient 路径：sync + in-process
|
||||
|
||||
```mermaid
|
||||
sequenceDiagram
|
||||
participant User as Python caller
|
||||
participant Client as DeerFlowClient.stream
|
||||
participant Agent as LangGraph<br/>agent.stream (sync)
|
||||
|
||||
User->>Client: for event in client.stream("hi"):
|
||||
Client->>Agent: stream(stream_mode=["values","messages","custom"])
|
||||
loop 每个 chunk
|
||||
Agent-->>Client: (mode, chunk)
|
||||
Client->>Client: 分发 mode<br/>构建 StreamEvent
|
||||
Client-->>User: yield StreamEvent
|
||||
end
|
||||
Client-->>User: yield StreamEvent(type="end")
|
||||
```
|
||||
|
||||
对比之下，sync 路径的每个环节都是显著更少的移动部件：
|
||||
|
||||
- 没有 `RunManager` —— 一次 `stream()` 调用对应一次生命周期，无需 run_id。
|
||||
- 没有 `StreamBridge` —— 直接 `yield`，生产和消费在同一个 Python 调用栈，不需要跨 task 中介。
|
||||
- 没有 JSON 序列化 —— `StreamEvent.data` 直接装原生 LangChain 对象（`AIMessage.content`、`usage_metadata` 的 `UsageMetadata` TypedDict）。Jupyter 用户拿到的是真正的类型，不是匿名 dict。
|
||||
- 没有 asyncio —— 调用者可以直接 `for event in ...`，不必写 `async for`。
|
||||
|
||||
---
|
||||
|
||||
## 消费语义：delta vs cumulative
|
||||
|
||||
LangGraph `messages` mode 给出的是 **delta**：每个 `AIMessageChunk.content` 只包含这一次新 yield 的 token，**不是**从头的累计文本。
|
||||
|
||||
这个语义和 LangChain 的 `fs2 Stream` 风格一致：**上游发增量，下游负责累加**。Gateway 路径里前端 `useStream` React hook 自己维护累加器；DeerFlowClient 路径里 `chat()` 方法替调用者做累加。
|
||||
|
||||
### `DeerFlowClient.chat()` 的 O(n) 累加器
|
||||
|
||||
```python
|
||||
chunks: dict[str, list[str]] = {}
|
||||
last_id: str = ""
|
||||
for event in self.stream(message, thread_id=thread_id, **kwargs):
|
||||
if event.type == "messages-tuple" and event.data.get("type") == "ai":
|
||||
msg_id = event.data.get("id") or ""
|
||||
delta = event.data.get("content", "")
|
||||
if delta:
|
||||
chunks.setdefault(msg_id, []).append(delta)
|
||||
last_id = msg_id
|
||||
return "".join(chunks.get(last_id, ()))
|
||||
```
|
||||
|
||||
**为什么不是 `buffers[id] = buffers.get(id,"") + delta`**：CPython 的字符串 in-place concat 优化仅在 refcount=1 且 LHS 是 local name 时生效；这里字符串存在 dict 里被 reassign，优化失效，每次都是 O(n) 拷贝 → 总体 O(n²)。实测 50 KB / 5000 chunk 的回复要 100-300ms 纯拷贝开销。用 `list` + `"".join()` 是 O(n)。
|
||||
|
||||
---
|
||||
|
||||
## 三个 id set 为什么不能合并
|
||||
|
||||
`DeerFlowClient.stream()` 在一次调用生命周期内维护三个 `set[str]`：
|
||||
|
||||
```python
|
||||
seen_ids: set[str] = set() # values 路径内部 dedup
|
||||
streamed_ids: set[str] = set() # messages → values 跨模式 dedup
|
||||
counted_usage_ids: set[str] = set() # usage_metadata 幂等计数
|
||||
```
|
||||
|
||||
乍看像是"三份几乎一样的东西"，实际每个管**不同的不变式**。
|
||||
|
||||
| Set | 负责的不变式 | 被谁填充 | 被谁查询 |
|
||||
|---|---|---|---|
|
||||
| `seen_ids` | 连续两个 `values` 快照里同一条 message 只生成一个 `messages-tuple` 事件 | values 分支每处理一条消息就加入 | values 分支处理下一条消息前检查 |
|
||||
| `streamed_ids` | 如果一条消息已经通过 `messages` 模式 token 级流过，values 快照到达时**不要**再合成一次完整 `messages-tuple` | messages 分支每发一个 AI/tool 事件就加入 | values 分支看到消息时检查 |
|
||||
| `counted_usage_ids` | 同一个 `usage_metadata` 在 messages 末尾 chunk 和 values 快照的 final AIMessage 里各带一份，**累计总量只算一次** | `_account_usage()` 每次接受 usage 就加入 | `_account_usage()` 每次调用时检查 |
|
||||
|
||||
### 为什么不能只用一个 set
|
||||
|
||||
关键观察：**同一个 message id 在这三个 set 里的加入时机不同**。
|
||||
|
||||
```mermaid
|
||||
sequenceDiagram
|
||||
participant M as messages mode
|
||||
participant V as values mode
|
||||
participant SS as streamed_ids
|
||||
participant SU as counted_usage_ids
|
||||
participant SE as seen_ids
|
||||
|
||||
Note over M: 第一个 AI text chunk 到达
|
||||
M->>SS: add(msg_id)
|
||||
Note over M: 最后一个 chunk 带 usage
|
||||
M->>SU: add(msg_id)
|
||||
Note over V: snapshot 到达，包含同一条 AI message
|
||||
V->>SE: add(msg_id)
|
||||
V->>SS: 查询 → 已存在，跳过文本合成
|
||||
V->>SU: 查询 → 已存在，不重复计数
|
||||
```
|
||||
|
||||
- `seen_ids` **永远在 values 快照到达时**加入，所以它是 "values 已处理" 的标记。一条只出现在 messages 流里的消息（罕见但可能），`seen_ids` 里永远没有它。
|
||||
- `streamed_ids` **在 messages 流的第一个有效事件时**加入。一条只通过 values 快照到达的非 AI 消息（HumanMessage、被 truncate 的 tool 消息），`streamed_ids` 里永远没有它。
|
||||
- `counted_usage_ids` **只在看到非空 `usage_metadata` 时**加入。一条完全没有 usage 的消息（tool message、错误消息）永远不会进去。
|
||||
|
||||
**集合包含关系**：`counted_usage_ids ⊆ (streamed_ids ∪ seen_ids)` 大致成立，但**不是严格子集**，因为一条消息可以在 messages 模式流完 text 但**在最后那个带 usage 的 chunk 之前**就被 values snapshot 赶上——此时它已经在 `streamed_ids` 里，但还不在 `counted_usage_ids` 里。把它们合并成一个 dict-of-flags 会让这个微妙的时序依赖**从类型系统里消失**，变成注释里的一句话。三个独立的 set 把不变式显式化了：每个 set 名对应一个可以口头回答的问题。
|
||||
|
||||
---
|
||||
|
||||
## 端到端：一次真实对话的事件时序
|
||||
|
||||
假设调用 `client.stream("Count from 1 to 15")`，LLM 给出 "one\ntwo\n...\nfifteen"（88 字符），tokenizer 把它拆成 ~35 个 BPE chunk。下面是事件到达序列的精简版：
|
||||
|
||||
```mermaid
|
||||
sequenceDiagram
|
||||
participant U as User
|
||||
participant C as DeerFlowClient
|
||||
participant A as LangGraph<br/>agent.stream
|
||||
|
||||
U->>C: stream("Count ... 15")
|
||||
C->>A: stream(mode=["values","messages","custom"])
|
||||
|
||||
A-->>C: ("values", {messages: [HumanMessage]})
|
||||
C-->>U: StreamEvent(type="values", ...)
|
||||
|
||||
Note over A,C: LLM 开始 yield token
|
||||
loop 35 次，约 476ms
|
||||
A-->>C: ("messages", (AIMessageChunk(content="ele"), meta))
|
||||
C->>C: streamed_ids.add(ai-1)
|
||||
C-->>U: StreamEvent(type="messages-tuple",<br/>data={type:ai, content:"ele", id:ai-1})
|
||||
end
|
||||
|
||||
Note over A: LLM finish_reason=stop，最后一个 chunk 带 usage
|
||||
A-->>C: ("messages", (AIMessageChunk(content="", usage_metadata={...}), meta))
|
||||
C->>C: counted_usage_ids.add(ai-1)<br/>(无文本，不 yield)
|
||||
|
||||
A-->>C: ("values", {messages: [..., AIMessage(complete)]})
|
||||
C->>C: ai-1 in streamed_ids → 跳过合成
|
||||
C->>C: 捕获 usage (已在 counted_usage_ids，no-op)
|
||||
C-->>U: StreamEvent(type="values", ...)
|
||||
|
||||
C-->>U: StreamEvent(type="end", data={usage:{...}})
|
||||
```
|
||||
|
||||
关键观察：
|
||||
|
||||
1. 用户看到 **35 个 messages-tuple 事件**，跨越约 476ms，每个事件带一个 token delta 和同一个 `id=ai-1`。
|
||||
2. 最后一个 `values` 快照里的 `AIMessage` **不会**再触发一个完整的 `messages-tuple` 事件——因为 `ai-1 in streamed_ids` 跳过了合成。
|
||||
3. `end` 事件里的 `usage` 正好等于那一份 cumulative usage，**不是它的两倍**——`counted_usage_ids` 在 messages 末尾 chunk 上已经吸收了，values 分支的重复访问是 no-op。
|
||||
4. 消费者拿到的 `content` 是**增量**："ele" 只包含 3 个字符，不是 "one\ntwo\n...ele"。想要完整文本要按 `id` 累加，`chat()` 已经帮你做了。

## 为什么这个设计容易出 bug，以及测试策略
|
||||
|
||||
本文档的直接起因是 bytedance/deer-flow#1969：`DeerFlowClient.stream()` 原本只订阅 `["values", "custom"]`，**漏了 `"messages"`**。结果 `client.stream("hello")` 等价于一次性返回，视觉上和 `chat()` 没区别。
|
||||
|
||||
这类 bug 有三个结构性原因：
|
||||
|
||||
1. **多协议层命名**：`messages` / `messages-tuple` / HTTP SSE `messages` 是同一概念的三个名字。在其中一层出错不会在另外两层报错。
|
||||
2. **多消费者模型**：Gateway 和 DeerFlowClient 是两套独立实现，**没有单一的"订阅哪些 mode"的 single source of truth**。前者订阅对了不代表后者也订阅对了。
|
||||
3. **mock 测试绕开了真实路径**：老测试用 `agent.stream.return_value = iter([dict_chunk, ...])` 喂 values 形状的 dict 模拟 state 快照。这样构造的输入**永远不会进入 `messages` mode 分支**，所以即使 `stream_mode` 里少一个元素，CI 依然全绿。
|
||||
|
||||
### 防御手段
|
||||
|
||||
真正的防线是**显式断言 "messages" mode 被订阅 + 用真实 chunk shape mock**：
|
||||
|
||||
```python
|
||||
# tests/test_client.py::test_messages_mode_emits_token_deltas
|
||||
agent.stream.return_value = iter([
|
||||
("messages", (AIMessageChunk(content="Hel", id="ai-1"), {})),
|
||||
("messages", (AIMessageChunk(content="lo ", id="ai-1"), {})),
|
||||
("messages", (AIMessageChunk(content="world!", id="ai-1"), {})),
|
||||
("values", {"messages": [HumanMessage(...), AIMessage(content="Hello world!", id="ai-1")]}),
|
||||
])
|
||||
# ...
|
||||
assert [e.data["content"] for e in ai_text_events] == ["Hel", "lo ", "world!"]
|
||||
assert len(ai_text_events) == 3 # values snapshot must NOT re-synthesize
|
||||
assert "messages" in agent.stream.call_args.kwargs["stream_mode"]
|
||||
```
|
||||
|
||||
**为什么这比"抽一个共享常量"更有效**：共享常量只能保证"用它的人写对字符串"，但新增消费者的人可能根本不知道常量在哪。行为断言强制任何改动都要穿过**实际执行路径**，改回 `["values", "custom"]` 会立刻让 `assert "messages" in ...` 失败。
|
||||
|
||||
### 活体信号：BPE 子词边界
|
||||
|
||||
回归的最终验证是让真实 LLM 数 1-15，然后看是否能在输出里看到 tokenizer 的子词切分：
|
||||
|
||||
```
|
||||
[5.460s] 'ele' / 'ven' eleven 被拆成两个 token
|
||||
[5.508s] 'tw' / 'elve' twelve 拆两个
|
||||
[5.568s] 'th' / 'irteen' thirteen 拆两个
|
||||
[5.623s] 'four'/ 'teen' fourteen 拆两个
|
||||
[5.677s] 'f' / 'if' / 'teen' fifteen 拆三个
|
||||
```
|
||||
|
||||
子词切分是 tokenizer 的外部事实，**无法伪造**。能看到它就说明数据流**逐 chunk** 地穿过了整条管道，没有被任何中间层缓冲成整段。这种"活体信号"在流式系统里是比单元测试更高置信度的证据。
