# 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
|
||||

* 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
|
||||
those enforcing the Code of Conduct, for a specified period of time. This
|
||||
includes avoiding interactions in community spaces as well as external channels
|
||||
like social media. Violating these terms may lead to a temporary or
|
||||
permanent ban.
|
||||
|
||||
### 3. Temporary Ban
|
||||
|
||||
**Community Impact**: A serious violation of community standards, including
|
||||
sustained inappropriate behavior.
|
||||
|
||||
**Consequence**: A temporary ban from any sort of interaction or public
|
||||
communication with the community for a specified period of time. No public or
|
||||
private interaction with the people involved, including unsolicited interaction
|
||||
with those enforcing the Code of Conduct, is allowed during this period.
|
||||
Violating these terms may lead to a permanent ban.
|
||||
|
||||
### 4. Permanent Ban
|
||||
|
||||
**Community Impact**: Demonstrating a pattern of violation of community
|
||||
standards, including sustained inappropriate behavior, harassment of an
|
||||
individual, or aggression toward or disparagement of classes of individuals.
|
||||
|
||||
**Consequence**: A permanent ban from any sort of public interaction within
|
||||
the community.

#### 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:

```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.

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`).
|
||||
|
||||
To route OpenAI models through `/v1/responses`, keep using `langchain_openai:ChatOpenAI` and set `use_responses_api: true` with `output_version: responses/v1`.
|
||||
|
||||
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.

### 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)

### 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。

**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)

- 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)

**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.

# 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 |

||||
- 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。

|

|
||||

|
||||
loop 每个 chunk
|
||||
Agent-->>Worker: (mode, chunk)
|
||||
Worker->>Bridge: publish(run_id, event, serialize(chunk))
|
||||
end
|
||||
Worker->>Bridge: publish_end(run_id)

||||

|
||||
SSE-->>Client: "event: <name>\ndata: <json>\n\n"
|
||||
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。

without changing their event-handling logic.

|

Token-level streaming
|
||||
~~~~~~~~~~~~~~~~~~~~~
|
||||
This method subscribes to LangGraph's ``messages`` stream mode, so
|
||||
``messages-tuple`` events for AI text are emitted as **deltas** as
|
||||
the model generates tokens, not as one cumulative dump at node
|
||||
completion. Each delta carries a stable ``id`` — consumers that
|
||||
want the full text must accumulate ``content`` per ``id``.
|
||||
``chat()`` already does this for you.
|
||||
|
||||
Tool calls and tool results are still emitted once per logical
|
||||
message. ``values`` events continue to carry full state snapshots
|
||||
after each graph node finishes; AI text already delivered via the
|
||||
``messages`` stream is **not** re-synthesized from the snapshot to
|
||||
avoid duplicate deliveries.
|
||||
|
||||
Why not reuse Gateway's ``run_agent``?
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
Gateway (``runtime/runs/worker.py``) has a complete streaming
|
||||
pipeline: ``run_agent`` → ``StreamBridge`` → ``sse_consumer``. It
|
||||
looks like this client duplicates that work, but the two paths
|
||||
serve different audiences and **cannot** share execution:
|
||||
|
||||
* ``run_agent`` is ``async def`` and uses ``agent.astream()``;
|
||||
this method is a sync generator using ``agent.stream()`` so
|
||||
callers can write ``for event in client.stream(...)`` without
|
||||
touching asyncio. Bridging the two would require spinning up
|
||||
an event loop + thread per call.
|
||||
* Gateway events are JSON-serialized by ``serialize()`` for SSE
|
||||
wire transmission. This client yields in-process stream event
|
||||
payloads directly as Python data structures (``StreamEvent``
|
||||
with ``data`` as a plain ``dict``), without the extra
|
||||
JSON/SSE serialization layer used for HTTP delivery.
|
||||
* ``StreamBridge`` is an asyncio-queue decoupling producers from
|
||||
consumers across an HTTP boundary (``Last-Event-ID`` replay,
|
||||
heartbeats, multi-subscriber fan-out). A single in-process
|
||||
caller with a direct iterator needs none of that.
|
||||
|
||||
So ``DeerFlowClient.stream()`` is a parallel, sync, in-process
|
||||
consumer of the same ``create_agent()`` factory — not a wrapper
|
||||
around Gateway. The two paths **should** stay in sync on which
|
||||
LangGraph stream modes they subscribe to; that invariant is
|
||||
enforced by ``tests/test_client.py::test_messages_mode_emits_token_deltas``
|
||||
rather than by a shared constant, because the three layers
|
||||
(Graph, Platform SDK, HTTP) each use their own naming
|
||||
(``messages`` vs ``messages-tuple``) and cannot literally share
|
||||
a string.

"""Custom vLLM provider built on top of LangChain ChatOpenAI.

vLLM 0.19.0 exposes reasoning models through an OpenAI-compatible API, but

LangChain's default OpenAI adapter drops the non-standard ``reasoning`` field
|

from assistant messages and streaming deltas. That breaks interleaved

thinking/tool-call flows because vLLM expects the assistant's prior reasoning to

be echoed back on subsequent turns.

- non-streaming responses
