If a trusted operator manages the configured skills directory through an external mount such as MinIO, NFS, or CSI, an administrator can call `POST /api/skills/reload` after changing files. This invalidates skill prompt caches for the current Gateway process and waits up to the bounded refresh timeout so subsequent runs rescan the latest files; running tasks are unchanged. A loader-level filesystem failure returns a generic server error and preserves the last successfully loaded process cache rather than publishing an empty catalog. Uvicorn workers and Kubernetes Pods must each be targeted separately. Direct mount writes bypass the validation, SkillScan, and history applied by DeerFlow's install/edit APIs, so only operator-controlled systems should have write access.
Skill installs and agent-managed skill edits run through **SkillScan**, a native deterministic safety scanner before the LLM-based skill scanner. Phase 1 runs offline with no Semgrep/OpenGrep dependency, blocks high-confidence `CRITICAL` findings such as private keys or shell execution, and passes warning findings to the LLM scanner for contextual review. Set `skill_scan.enabled: false` in `config.yaml` to disable only the deterministic analyzers; safe archive extraction and the LLM scanner still run.
Skill installs and agent-managed skill edits run through **SkillScan**, a native deterministic safety scanner before the LLM-based skill scanner. Phase 1 runs offline with no Semgrep/OpenGrep dependency, blocks high-confidence `CRITICAL` findings such as private keys or shell execution, and passes warning findings to the LLM scanner for contextual review. Python instance-client exfiltration checks follow a minimal same-scope evidence chain: a simple name bound to a known client constructor, optional name-to-name aliases, and an actual outbound method or context-manager use supported by that constructor. Constructor roots must be proven imports; bare canonical-looking names are not inferred as modules. Nested scopes do not inherit client handles and inherit only constructor import aliases that are never rebound in the enclosing scope. Comprehensions, walrus-bearing statements, annotations, complex binding targets, unsupported operations, and ambiguous branch flows produce no finding from this signal; skipped constructs conservatively invalidate every name they may bind so stale client state cannot create a finding. A deterministic work budget or recursion limit reached by this best-effort analysis does not discard findings already collected for the file. Set `skill_scan.enabled: false` in `config.yaml` to disable only the deterministic analyzers; safe archive extraction and the LLM scanner still run.
DeerFlow also ships with **skill-reviewer**, a public skill for read-only skill quality review. It uses the built-in `review_skill_package` tool to inspect installed skills, local packages, archives, or pasted `SKILL.md` content without activating the target skill, binding its secrets, executing its scripts, or installing it. The tool returns a compact, tag-neutralized JSON payload to the model context and keeps the full raw review payload in the tool artifact for programmatic consumers. The deterministic review core reuses DeerFlow parsing and SkillScan facts, emits versioned JSON contracts under `contracts/skill_review/`, and can be run from the backend CLI:

The Web UI composer can polish draft input before sending. The rewrite runs as a short Gateway LLM request using the `input_polish` model configuration, keeps slash skill prefixes such as `/data-analysis`, and only replaces the local draft after the user clicks the polish button; it does not create a thread run or persist a message.
Unsent Web UI composer drafts survive page reloads and switching between conversations within the same browser tab. Drafts are isolated by user, agent, and conversation, include a selected slash skill when present, and are cleared once a send is accepted. Attachments and quoted conversation context are intentionally not persisted.
The Web UI composer also supports browser-based voice dictation when the browser exposes the Web Speech API. The microphone button transcribes speech into the local draft only; DeerFlow receives only the transcribed text, while audio handling is delegated to the browser or operating system speech-recognition service according to that environment's policy. Users can review or edit the text before sending.
Interrupted first-turn runs still persist a fallback conversation title, so stopping a streaming response does not leave the thread as "Untitled" after refresh.
In the Web UI, completed assistant turns can be branched into a new main conversation. The new thread starts from that turn's checkpoint. Because workspace files are not checkpointed, the branch only receives a best-effort copy of the current workspace when you branch from the latest turn; branching from an older turn keeps just the restored message history so the branch never inherits files that were created in a later part of the conversation.
Web UI chat links percent-encode custom thread identifiers before placing them in route segments, so reserved URL characters such as `#` and `?` do not change which conversation is opened.

3. `extensions_config.json` in current directory (backend/)
4. `extensions_config.json` in parent directory (project root - **recommended location**)
Extensions are optional only in the fallback *search* mode (priority 3-4 above): `ExtensionsConfig.resolve_config_path()` returns `None` when neither an explicit `config_path` nor `DEER_FLOW_EXTENSIONS_CONFIG_PATH` is given and the search locations find nothing. An explicit `config_path` argument or a set `DEER_FLOW_EXTENSIONS_CONFIG_PATH` (priority 1-2) is an operator assertion that one particular file must be used, so a missing file in either of those modes raises `FileNotFoundError` instead — including when the file existed earlier and has since been deleted. The MCP tools cache's staleness check (`deerflow.mcp.cache._resolve_config_path`) is a narrow, deliberate exception to that rule: it catches that `FileNotFoundError` locally and treats it as "unconfigured" so a previously-valid config disappearing mid-run degrades the cache to serving its last-known-good tools instead of raising out of a per-request hot path (see the MCP System section below).

The Python instance-client signal deliberately follows only a one-level, same-scope evidence chain (PR #4265 review): a proven imported constructor bound to a simple name, optional name-to-name alias propagation, rebinding invalidation, and a constructor-supported outbound method or context-manager use; bare canonical-looking names never fall back to module identity. Nested scopes never inherit client handles and inherit only constructor aliases proven stable by a binding-only enclosing-scope prepass. Comprehensions, walrus-bearing statements, annotations, executable expressions inside complex binding targets, unsupported operations, and ambiguous flows produce no finding from this signal; skipped constructs invalidate all names they may bind, while representative false negatives are pinned by `test_python_declared_false_negatives_stay_unreported`. Compound bodies are walked from isolated copies so wrapping code in `if True:` is not a bypass, while copied scope entries, binding-only prepasses, and AST visits consume a deterministic work budget and the walk stops after its first sink. Budget or recursion exhaustion skips only this best-effort signal and retains deterministic findings already collected for the file.

- **Skill Review Core**: `packages/harness/deerflow/skills/review/` provides read-only package snapshots, deterministic facts, resource/eval analysis, report rendering, and the CLI (`python -m deerflow.skills.review.cli`). It reuses the shared frontmatter helper and SkillScan; it must not import `app.*`, execute target scripts, install dependencies, or call networks. JSON contracts live in `contracts/skill_review/`. The `review_skill_package` built-in tool labels results with `review_subject_entry` and never `skill_context_entry`, so reviewing a target does not activate it, bind its `required-secrets`, or apply its `allowed-tools`. Its model-visible `ToolMessage.content` is a compact JSON payload with untrusted control tags neutralized; the full raw review payload, including Markdown renders, stays in `ToolMessage.artifact`. CI should run the CLI with `--fail-on error --fail-on-incomplete` so blocker/error findings and truncated/not-assessed packages fail the gate. The public `skills/public/skill-reviewer` skill owns semantic readiness review and suggestions only; mutation and runtime experiments remain owned by `skill-creator`.

Request trace correlation is controlled by `logging.enhance.enabled` at **both** entry points, gated through the shared helper `deerflow.config.app_config.is_trace_correlation_enabled` so the Gateway and embedded paths cannot drift:
- **Gateway HTTP**: `app.gateway.trace_middleware.TraceMiddleware` binds one request-level trace id per HTTP request, inheriting inbound `X-Trace-Id` when present or generating a new id otherwise. The middleware writes the final value to every HTTP response at `http.response.start`, which covers SSE / streaming responses without consuming the body.
- **Gateway HTTP**: `app.gateway.trace_middleware.TraceMiddleware` binds one request-level trace id per HTTP request, inheriting inbound `X-Trace-Id` when present or generating a new id otherwise. A **valid** inbound header also marks the request so `runtime/runs/worker.py` prefers that id over `config.metadata.deerflow_trace_id`, keeping logs, response headers, Langfuse, and runtime context aligned when callers send both. The middleware writes the final value to every HTTP response at `http.response.start`, which covers SSE / streaming responses without consuming the body.
- **Embedded / TUI / CLI**: `DeerFlowClient.stream()` mints (or inherits) a request-level trace id per turn only when the flag is on. When it is off, no fresh id is minted — a caller that explicitly wraps `stream()` in `request_trace_context(...)` still opts in, because the downstream `get_current_trace_id()` read propagates that value into Langfuse metadata regardless of the flag. Because `stream()` is a sync generator (which shares the caller's context), the id binding is set/reset around each `next()` step rather than around `yield from`: this keeps LangGraph node execution and its log records inside the binding, while returning control to the caller with the ContextVar restored — avoids cross-request leak between yields and `ValueError: <Token> was created in a different Context` on GC-driven close of an abandoned generator (regression pinned by `tests/test_client_langfuse_metadata.py::test_stream_does_not_leak_trace_id_to_caller_context_between_yields` and `::test_stream_abandoned_generator_close_does_not_raise_cross_context`).
The same ContextVar value is injected into enhanced log records as `trace_id` and into Langfuse metadata as `deerflow_trace_id`.

Instructions:
1. Analyze the conversation for important information about the user
2. Extract relevant facts, preferences, and context with specific details (numbers, names, technologies)
3. Update the memory sections as needed following the detailed length guidelines below
Before extracting facts, perform a structured reflection on the conversation:
1. Error/Retry Detection: Did the agent encounter errors, require retries, or produce incorrect results?
If yes, record the root cause and correct approach as a high-confidence fact with category "correction".
2. User Correction Detection: Did the user correct the agent's direction, understanding, or output?
If yes, record the correct interpretation or approach as a high-confidence fact with category "correction".
Include what went wrong in "sourceError" only when category is "correction" and the mistake is explicit in the conversation.
3. Project Constraint Discovery: Were any project-specific constraints discovered during the conversation?
If yes, record them as facts with the most appropriate category and confidence.
{correction_hint}
Memory Section Guidelines:
**User Context** (Current state - concise summaries):
- workContext: Professional role, company, key projects, main technologies (2-3 sentences)
Example: Core contributor, project names with metrics (16k+ stars), technical stack
- personalContext: Languages, communication preferences, key interests (1-2 sentences)
Example: Bilingual capabilities, specific interest areas, expertise domains
- topOfMind: Multiple ongoing focus areas and priorities (3-5 sentences, detailed paragraph)
Example: Primary project work, parallel technical investigations, ongoing learning/tracking
Include: Active implementation work, troubleshooting issues, market/research interests
Note: This captures SEVERAL concurrent focus areas, not just one task
**History** (Temporal context - rich paragraphs):
- recentMonths: Detailed summary of recent activities (4-6 sentences or 1-2 paragraphs)
Timeline: Last 1-3 months of interactions
Include: Technologies explored, projects worked on, problems solved, interests demonstrated
- earlierContext: Important historical patterns (3-5 sentences or 1 paragraph)
Timeline: 3-12 months ago
Include: Past projects, learning journeys, established patterns
- longTermBackground: Persistent background and foundational context (2-4 sentences)
Timeline: Overall/foundational information
Include: Core expertise, longstanding interests, fundamental working style
**Facts Extraction**:
- Extract specific, quantifiable details (e.g., "16k+ GitHub stars", "200+ datasets")
- Include proper nouns (company names, project names, technology names)
- Preserve technical terminology and version numbers
- Categories:
* preference: Tools, styles, approaches user prefers/dislikes
* knowledge: Specific expertise, technologies mastered, domain knowledge
* context: Background facts (job title, projects, locations, languages)
* behavior: Working patterns, communication habits, problem-solving approaches
* goal: Stated objectives, learning targets, project ambitions
* correction: Explicit agent mistakes or user corrections, including the correct approach
- Fact lifetime (``expected_valid_days``, optional integer):
How many days before this fact should be reviewed for possible removal.
The system schedules review automatically; omit when uncertain.
* <= 14: highly transient - active bugs, immediate tasks, today's focus
* 15-60: short-term - current experiments, in-progress side projects, near-term goals
* 60-180: medium-term - current role, active tech stack, ongoing preferences
* 180-365: stable - professional background, established working patterns
* > 365: very stable - core skills, native language, personality traits
Assign the value that semantically fits; values above the server-configured
ceiling are silently reduced on storage.
- Confidence levels:
* 0.9-1.0: Explicitly stated facts ("I work on X", "My role is Y")
* 0.7-0.8: Strongly implied from actions/discussions
* 0.5-0.6: Inferred patterns (use sparingly, only for clear patterns)
**What Goes Where**:
- workContext: Current job, active projects, primary tech stack
- personalContext: Languages, personality, interests outside direct work tasks
- topOfMind: Multiple ongoing priorities and focus areas user cares about recently (gets updated most frequently)
Should capture 3-5 concurrent themes: main work, side explorations, learning/tracking interests
- recentMonths: Detailed account of recent technical explorations and work
- earlierContext: Patterns from slightly older interactions still relevant
- longTermBackground: Unchanging foundational facts about the user
**Multilingual Content**:
- Preserve original language for proper nouns and company names
- Keep technical terms in their original form (DeepSeek, LangGraph, etc.)
- Note language capabilities in personalContext

Important Rules:
- Only set shouldUpdate=true if there's meaningful new information
- Follow length guidelines: workContext/personalContext are concise (1-3 sentences), topOfMind and history sections are detailed (paragraphs)
- Include specific metrics, version numbers, and proper nouns in facts
- Only add facts that are clearly stated (0.9+) or strongly implied (0.7+)
- Use category "correction" for explicit agent mistakes or user corrections; assign confidence >= 0.95 when the correction is explicit
- Include "sourceError" only for explicit correction facts when the prior mistake or wrong approach is clearly stated; omit it otherwise
- Remove facts that are contradicted by new information
- When updating topOfMind, integrate new focus areas while removing completed/abandoned ones
Keep 3-5 concurrent focus themes that are still active and relevant
- For history sections, integrate new information chronologically into appropriate time period
- Preserve technical accuracy - keep exact names of technologies, companies, projects
- Focus on information useful for future interactions and personalization
- IMPORTANT: Do NOT record file upload events in memory. Uploaded files are
session-specific and ephemeral — they will not be accessible in future sessions.
Recording upload events causes confusion in subsequent conversations.

The following facts have reached their individual review window and may no longer
accurately reflect the user's current situation. Each entry shows a ``valid:Nd``

For each fact, decide KEEP, REMOVE, or EXTEND:
- KEEP: Still likely valid - even if not mentioned in this conversation.
Stable attributes (native language, core expertise, personality traits) often
remain true indefinitely.
- REMOVE: Outdated, contradicted by recent context, or no longer relevant.
Examples: tech-stack migrations, job changes, relocated offices, abandoned projects.
- EXTEND: Keep but recalibrate the review window (see below).
Add REMOVE decisions to "staleFactsToRemove" in your output JSON.
Each entry must be {{"id": "fact_id", "reason": "brief explanation"}}.
The reason should cite what signal in the conversation (or absence thereof)
supports the removal.
Optionally, for facts you KEEP and wish to recalibrate, add them to
"staleFactsToExtend" with the number of days from now before the next review:
{{"id": "fact_id", "extend_by_days": 365, "reason": "brief explanation"}}
Use this when the current window seems miscalibrated - e.g. a core skill marked
``valid:30d`` that is clearly stable, or a goal nearing completion whose window
should shrink. Omit facts whose current window already seems appropriate.
Be conservative - when in doubt, KEEP. Removing a valid fact is worse than
keeping a slightly stale one, because the next review cycle will re-evaluate it."""

- Include specific metrics, version numbers, and proper nouns in facts
- Only add facts that are clearly stated (0.9+) or strongly implied (0.7+)
- Use category "correction" for explicit agent mistakes or user corrections; assign confidence >= 0.95 when the correction is explicit
- Include "sourceError" only for explicit correction facts when the prior mistake or wrong approach is clearly stated; omit it otherwise
- Remove facts that are contradicted by new information
- When updating topOfMind, integrate new focus areas while removing completed/abandoned ones
Keep 3-5 concurrent focus themes that are still active and relevant
- For history sections, integrate new information chronologically into appropriate time period
- Preserve technical accuracy - keep exact names of technologies, companies, projects
- Focus on information useful for future interactions and personalization
- IMPORTANT: Do NOT record file upload events in memory. Uploaded files are
session-specific and ephemeral — they will not be accessible in future sessions.
Recording upload events causes confusion in subsequent conversations.
Return ONLY valid JSON, no explanation or markdown.

## Staleness Review
The following facts have reached their individual review window and may no longer
accurately reflect the user's current situation. Each entry shows a ``valid:Nd``
annotation - the number of days this fact was expected to remain valid before
re-evaluation. Use it to calibrate conservatism: a ``valid:30d`` fact was
considered volatile at creation; a ``valid:365d`` fact was considered stable.
<stale_facts>
{stale_facts}
</stale_facts>
For each fact, decide KEEP, REMOVE, or EXTEND:
- KEEP: Still likely valid - even if not mentioned in this conversation.
Stable attributes (native language, core expertise, personality traits) often
remain true indefinitely.
- REMOVE: Outdated, contradicted by recent context, or no longer relevant.
Examples: tech-stack migrations, job changes, relocated offices, abandoned projects.
- EXTEND: Keep but recalibrate the review window (see below).
Add REMOVE decisions to "staleFactsToRemove" in your output JSON.
Each entry must be {{"id": "fact_id", "reason": "brief explanation"}}.
The reason should cite what signal in the conversation (or absence thereof)
supports the removal.
Optionally, for facts you KEEP and wish to recalibrate, add them to
"staleFactsToExtend" with the number of days from now before the next review:
{{"id": "fact_id", "extend_by_days": 365, "reason": "brief explanation"}}
Use this when the current window seems miscalibrated - e.g. a core skill marked
``valid:30d`` that is clearly stable, or a goal nearing completion whose window
should shrink. Omit facts whose current window already seems appropriate.
Be conservative - when in doubt, KEEP. Removing a valid fact is worse than
keeping a slightly stale one, because the next review cycle will re-evaluate it.

``ExtensionsConfig.resolve_config_path()`` raises ``FileNotFoundError``
when an explicit `config_path` or `DEER_FLOW_EXTENSIONS_CONFIG_PATH`
points at a file that does not exist. That is deliberate for callers that
load the config for actual use (e.g. ``ExtensionsConfig.from_file()`` via
``get_mcp_tools()``): an operator-asserted explicit path going missing is
a real misconfiguration and must be surfaced loudly.
This helper is not one of those callers — it only backs the cache's own
staleness check (``_is_cache_stale``, via ``_current_config_state``),
which runs on every ``get_cached_mcp_tools()`` call and just wants to know
whether the previously loaded config is still current. If the file behind
a previously-valid explicit/env-var path becomes unreadable later
(deleted mid-run, a Docker mount hiccup, ...), raising here would crash
every subsequent call to that hot per-request path instead of leaving the
cache serving its last-known-good MCP tools. So this wrapper catches that
specific failure and treats it the same as "unconfigured", matching
``_is_cache_stale()``'s existing fail-soft handling of a ``None`` config
state (see its docstring). Scoping the catch here — rather than making
``resolve_config_path()`` itself return ``None`` for every caller — keeps
the loud failure intact for callers that actually need the file.

# DeerFlow behavioural tests (Monocle Test Tools)
Trace-based tests for DeerFlow. Monocle records each run as a structured trace
(the agent invocation, every tool call, token usage, timings), and these tests
assert against that trace with [Monocle Test Tools](https://github.com/monocle2ai/monocle).
## How this is meant to be used
Instrument the agent with Monocle and run it against a question. Once it answers
the way you expect and makes the agent and tool calls you expect, capture that
run as a trace. That trace is a golden, labelled reference for the question: a
record of correct behaviour, not just sample data. You turn it into assertions
(the offline example shows how), and then you point those same assertions at the
live agent for the same question, so every later run has to reproduce that
behaviour. The offline test is where you pin down what good looks like; the live
test is what enforces it against a real run.
## Layers
The suite has two:
- **One offline example** (`test_assertion_api_example`) loads a recorded trace
from file and shows the full fluent vocabulary in one place. It needs no keys
and no network. Because it asserts against frozen JSON, it guards the trace
format and the asserter wiring, not DeerFlow's behaviour. Treat it as the
worked example for writing your own assertions.
- **Two live tests** drive the agent end-to-end and assert on the trace the real
run emits. These are the behavioural guards: a change that alters routing, tool
selection, or token cost is caught here. They are explicit opt-in via
`MONOCLE_LIVE_TESTS=1` and skip by default, so a plain run never spends model
tokens or hits the network, even on a fully configured checkout.
## Layout
- `test_deerflow.py` — the offline example + two live tests
- `conftest.py` — the `run_agent` fixture (live path only)
- `_helpers.py` — paths and `run_deerflow()`
- `traces/` — the recorded trace the offline example loads
- `requirements.txt` — standalone dependencies
## The committed trace
`traces/web_research_ev_battery.json` is a full, unmodified recording of a real
run, committed whole so the offline example parses a genuine trace. That means
it embeds the DeerFlow system prompt as of the recording date and the content
the run fetched from the web, alongside the span structure the assertions read.
It contains no credentials.
The offline assertions are pinned to this exact trace and to the
`monocle_apptrace` 0.8.8 span shapes: the `LangGraph` agent span name, the tool
names, and the input phrasing. A rename of any of those breaks the offline test
even when behaviour is unchanged; re-record the trace when the prompt, tools, or
model change.
## Run
`monocle_test_tools` hard-depends on the ML eval stack (torch, transformers,
sentence-transformers), so it is a standalone `requirements.txt` install rather
than a backend dependency. When it is absent (e.g. a plain backend venv) the
whole suite skips cleanly via `pytest.importorskip`.
Because that dependency is deliberately absent from the backend deps, **none of
these tests run in CI** — `make test` collects and skips the whole module,
including the offline example. This is an on-demand suite: install the
requirements and run it locally (or wire a dedicated CI job with the
requirements installed) when changing agent behaviour, tools, or routing.
```bash
# from the repo root
pip install -r backend/tests/monocle/requirements.txt
# offline — no network, no keys; the live tests skip unless opted in
pytest backend/tests/monocle/
# opt in to the live behavioural tests (real model calls + web requests)
MONOCLE_LIVE_TESTS=1 pytest backend/tests/monocle/
```
Or, following the backend convention (from `backend/`, with uv):
```bash
uv pip install -r tests/monocle/requirements.txt
uv run pytest tests/monocle/ # offline
MONOCLE_LIVE_TESTS=1 uv run pytest tests/monocle/ # + live
```
The live tests are opt-in by design: without `MONOCLE_LIVE_TESTS=1` they skip
even on a checkout where credentials and `config.yaml` are present, so the
default command can never spend tokens or write to a sandbox. When opted in,
they still skip if the DeerFlow app is not importable or `config.yaml` is
missing. Model credentials are validated by the configured model itself —
`config.yaml` may select any provider (OpenAI, Anthropic, Gemini, and so on),
so there is no hard-coded key requirement. DeerFlow's `web_search` is
DuckDuckGo and needs no key of its own.
The `monocle_trace_asserter` fixture is provided by `monocle_test_tools`' own
pytest plugin, which registers automatically on install (a `pytest11` entry
point); no `pytest_plugins` configuration is needed.
## Add your own test
1. Run DeerFlow under Monocle and capture a trace of a run you are happy with
(Monocle writes trace JSON to `.monocle/` by default).
2. For an offline example, move it into `traces/` and load it with
`monocle_trace_asserter.with_trace_source("file", trace_path=path)`.
3. For a behavioural test, drive the agent live via the `run_agent` fixture and
`monocle_trace_asserter.validator.test_workflow(run_agent, {"test_input": (...)})`.
4. Assert with the fluent API: `called_agent(...)`, `called_tool(...)`,
`contains_input` / `contains_any_output(...)`, `under_token_limit(...)`,
`under_duration(..., span_type="workflow")`.
## Evaluations (note)
Structural assertions are the coverage here. Content/quality evaluations are
**not** wired in this suite because, on the current `monocle_test_tools`, local
evals do **not** compose with file-loaded traces:
- Declarative `test_spans[].eval` (`comparer:"metric"`) is silently ignored by
`validator.validate()` — `_evaluate_span` has no call sites, so an assertion
that should fail (e.g. a required keyword that is absent) passes vacuously.
- The fluent `check_eval()` path is wired for the Okahu eval-service signature
(`filtered_spans=`), which the local evaluators (`keyword_presence`, etc.) do
not accept — it raises `TypeError`.
So local evals are omitted rather than added as vacuous no-ops. The Okahu eval
layer (needs `OKAHU_API_KEY`) remains an option for content grading.

"""Trace-based behavioural tests for DeerFlow, using Monocle Test Tools.
Two layers:
* One **offline example** (``test_assertion_api_example``) loads a recorded
trace from file and shows the full fluent vocabulary in one place. It needs no
keys and no network, but because it asserts against frozen JSON it guards the
trace format and the asserter wiring, not DeerFlow's behaviour. Treat it as the
worked example for writing your own assertions.
* Two **live tests** drive the agent end-to-end through ``run_agent`` and assert
on the trace the real run emits. These are the behavioural guards: a change
that alters routing, tool selection, or token cost is caught here. They are
**explicit opt-in** via ``MONOCLE_LIVE_TESTS=1`` (default off, so a plain run
never spends tokens or hits the network) and need the DeerFlow app plus the
configured model's credentials.
The whole module is skipped when ``monocle_test_tools`` is not installed (see the
``importorskip`` below), so a plain backend venv collects it without error.

a real misconfiguration that must surface loudly (PR #4275 review,
fancyboi999 [P1]) instead of silently starting with every MCP server and
skill absent.
``deerflow.mcp.cache._resolve_config_path`` calls
``ExtensionsConfig.resolve_config_path()`` with no args and therefore
hits this exact branch whenever the env var is set; that module has its
own narrower catch around this specific exception so the MCP tools-cache
staleness check does not crash on every request once the file goes
missing after a successful init — see
``test_config_deleted_after_init_via_real_env_resolution_does_not_raise``
in ``test_mcp_cache.py`` for that regression.

5. TanStack Query manages server state; localStorage stores user settings
6. Components subscribe to thread state and render updates
Composer drafts are tab-scoped browser state. `core/threads/composer-draft.ts` stores only text plus the selected slash-skill name in `sessionStorage`, keyed by user, agent, and logical conversation scope. New-chat pages pass the stable scope `"new"` because their runtime `threadId` is a fresh UUID on every reload; established conversations use their real thread ID. `InputBox` waits for enabled skills before restoring a skill chip, degrades a missing/disabled skill back to editable slash text, and clears the stored draft through `SendMessageOptions.onSent` only after the send passes the in-flight guard. Attachments, sidecar quotes, voice state, and polish undo state are not persisted.
Auth UI note: the login page's "keep me signed in" option submits only `remember_me` to the Gateway and may persist only the email address through `core/auth/remember-login.ts`. Passwords and tokens must never be stored in frontend storage; the `HttpOnly access_token` and readable `csrf_token` cookies remain Gateway-owned.
`/goal` and `/compact` are built-in composer commands, not skill activations. `src/components/workspace/input-box.tsx` intercepts `/goal`, `/goal clear`, and `/goal <condition>` before normal chat submission, calling Gateway `GET/PUT/DELETE /api/threads/{thread_id}/goal`. Setting `/goal <condition>` also submits the condition text as the next user task so the agent starts running immediately; status and clear do not start a run. Goal and compact requests are tied to the current `threadId` with an `AbortController`, so switching threads or unmounting the composer aborts in-flight requests and stale responses cannot update the new thread's composer state. The chat pages render `GoalStatus` above the composer from `AgentThreadState.goal`, with local optimistic state until the next stream `values` update arrives. `/compact` calls `POST /api/threads/{thread_id}/compact` to summarize older active context while leaving the full visible chat history intact; it is skipped on new/empty threads and blocked server-side while a run is in flight.

- **Server Components by default**, `"use client"` only for interactive components
- **Thread hooks** (`useThreadStream`, `useSubmitThread`, `useThreads`) are the primary API interface
- **Thread routes** — construct Web UI chat paths through `core/threads/utils.ts::pathOfThread()`, which percent-encodes both custom agent names and thread IDs before inserting them into route segments
- **LangGraph client** is a singleton obtained via `getAPIClient()` in `core/api/`
- **Environment validation** uses `@t3-oss/env-nextjs` with Zod schemas (`src/env.js`). Skip with `SKIP_ENV_VALIDATION=1`
- **Subtask step history and runtime metadata** (`core/tasks/`) — the subtask card shows a subagent's full step timeline (#3779): its assistant reasoning turns interleaved with the tools it ran. `Subtask.steps[]` is accumulated live from `task_running` events (appended via `mergeSteps`, not overwritten) and backfilled on expand for historical runs by `fetchSubtaskSteps`, which pages the events endpoint scoped to one task (GET `/runs/{runId}/events?event_types=subagent.step&task_id=…&after_seq=…`) until a short page, so the run-wide limit can't truncate the timeline. `task_started` carries the effective `model_name`; `task_running` carries a cumulative usage snapshot after each completed LLM call. `core/tasks/lifecycle.ts` normalizes these additive events, and `computeNextSubtask` keeps the largest cumulative total so replayed or late SSE frames cannot double-count or roll the folded card backward. Terminal ToolMessage metadata (`subagent_model_name` / `subagent_token_usage`) restores the same values from normal history after reload; no per-card event fetch is needed. `core/tasks/steps.ts` is the pure step model: `messageToStep` (live), `eventsToSteps` (reload), `mergeSteps` (dedup by `message_index`), and `stepsForDisplay` (what the card renders — keeps tool steps + AI steps with text, drops the trailing final-answer AI step when completed since it's shown as `result`). `core/tasks/context.tsx`'s `useUpdateSubtask` applies updates against a `tasksRef` mirroring the latest state (not a closure snapshot), so a late-resolving `fetchSubtaskSteps` backfill merges into current state instead of clobbering SSE steps or sibling subtasks that arrived meanwhile. The owning `run_id` is carried onto history content messages in `buildVisibleHistoryMessages` so the card can resolve the events endpoint.
