The lead-agent prompt uses the same clamped values, so model-visible limits match enforcement.

Previously the exception fell through to the generic handler and was misclassified as `FAILED`, so the lead could not tell "broken subagent" from "out of budget" and the work already streamed into `final_state` was discarded. `task_tool.py` returns it through the shared `_task_result_command(status="max_turns_reached", result=partial, error=cap)`, which `format_subagent_result_message` renders as `Task reached max turns. Partial result: ` and `make_subagent_additional_kwargs` stamps on `additional_kwargs` — `max_turns_reached` is the one status that carries **both** `subagent_result_brief`/`subagent_result_sha256` (the recovered partial work, like `completed`) and `subagent_error` (the cap notice). The polling loop emits a `task_failed` event so the card transitions out of running; the structured `subagent_status` is the precise reason. The cross-language status contract (`contracts/subagent_status_contract.json` + `subagents/status_contract.py` + `frontend/.../subtask-result.ts`) collapses `max_turns_reached` to the frontend's `failed` pill while the cap detail and recovered work survive on `error`/`result_brief`; the durable delegation ledger prefers the partial `result_brief` and renders model-facing guidance to reuse it, retry with a tighter scope, or raise the per-agent `max_turns`. -**Step capture & persistence (#3779)**: `executor.py` captures both assistant turns (`AIMessage`) **and** tool outputs (`ToolMessage`) via `subagents/step_events.py::capture_new_step_messages`, which walks the *newly-appended tail* of each `stream_mode="values"` chunk (not just `messages[-1]`) so a multi-tool-call turn — where LangGraph's `ToolNode` appends several `ToolMessage`s in one super-step — keeps every tool output instead of dropping all but the last. `runtime/runs/worker.py::_SubagentEventBuffer` additionally persists these `task_*` custom events to the `RunEventStore` as `subagent.start`/`subagent.step`/`subagent.end` (`category="subagent"`, `task_id` in `metadata`). It **batches** writes via `put_batch` (flushing on a terminal `subagent.end`, at `FLUSH_THRESHOLD` events, and in the worker's `finally`) rather than one `put()` per step, since `put()` is a documented low-frequency path (per-thread advisory lock per call) and a deep subagent (`max_turns=150`) emits hundreds of steps on the hot stream loop. `build_subagent_step` caps both the per-step `text` and each tool call's serialized `args` at `SUBAGENT_STEP_MAX_CHARS` (flagged `truncated` / `args_truncated`) so a large `write_file`/`bash` payload can't produce an unbounded row. The dedicated category keeps them out of `list_messages` (the thread feed) while `list_events` returns them for the frontend's fetch-on-expand backfill. `list_events` accepts `task_id` (filters on `metadata["task_id"]` — SQL-side in `DbRunEventStore` via `event_metadata["task_id"].as_string()`, in-memory in the JSONL/memory stores) plus an `after_seq` forward cursor, so the card pages through one subagent's steps without the run-wide `limit` truncating the tail (no schema migration: the filter rides the existing run-scoped index). `step_events.py` is a pure, unit-tested layer (`build_subagent_step` / `subagent_run_event`). -**Deferred MCP tools** (if `tool_search.enabled`): `SubagentExecutor._build_initial_state` assembles deferral after policy filtering via the shared `assemble_deferred_tools` (fail-closed), appends the `tool_search` tool, injects the `` section into the subagent's `SystemMessage`, and threads the setup to `_create_agent`, which attaches `DeferredToolFilterMiddleware` through `build_subagent_runtime_middlewares(deferred_setup=...)`. Subagents thus withhold full MCP schemas until promotion, same as the lead agent; each task run gets a fresh `ThreadState` so promotion is isolated per run +**Handled LLM failures**: `LLMErrorHandlingMiddleware` deliberately converts provider/model exceptions into an `AIMessage` so the graph can end cleanly, stamping `additional_kwargs.deerflow_error_fallback=true` plus error metadata. Clean graph termination does not imply subagent success: `SubagentExecutor` inspects the last assistant message at terminalization and maps a marked fallback to `SubagentStatus.FAILED`, which then emits `task_failed` and the existing structured `subagent_error`. Only the marker is authoritative — error-looking assistant prose without it remains a normal completed result, so neither the executor nor frontend parses display text as a status protocol. +**Guardrail caps & `stop_reason` (#3875 Phase 2)**: three independent axes can end a subagent run early, and all now surface *why* through one additive field rather than a new status enum. **Turn axis**: `recursion_limit` on the subagent `run_config` equals `max_turns`, so exhausting the turn budget raises `GraphRecursionError` from `agent.astream`; `executor.py::_aexecute` catches it specifically (before the generic `except Exception`). **Token axis**: `TokenBudgetMiddleware` is attached per-agent via `build_subagent_runtime_middlewares` from `subagents.token_budget` (default `max_tokens` **coupled to `summarization.enabled`** — 1,000,000 when subagent summarization is on, 2,000,000 when off, warn at 0.7, hard-stop at 1.0; a user-set budget always wins regardless of the switch — #3875 Phase 3; a backstop against a subagent that burns tokens on trivial work). It does *not* raise: at the hard-stop threshold it strips the in-flight turn's tool calls, forces `finish_reason="stop"`, and lets the run complete naturally with a final answer. **Loop axis**: `LoopDetectionMiddleware` (attached at the same point) catches repeated identical tool-call sets — or one tool *type* called many times with varying args — and its hard-stop likewise strips `tool_calls` and forces a final answer without raising, recording `loop_capped`. Each guard exposes its cap on a per-`run_id` `consume_stop_reason(run_id)` accessor; `_aexecute` collects **every** middleware with that method (duck-typed via `hasattr`, so the executor has no import coupling to the guard classes) and surfaces the first non-`None` reason — adding a future guard needs no executor change. **Surfacing**: whichever axis fired, `_aexecute` stamps a normal status plus an additive reason — `completed` + `stop_reason=token_capped|turn_capped|loop_capped` when a usable final answer (or partial recovered from the last streamed chunk via `_extract_final_result` → `utils/messages.py::message_content_to_text`, returning a `"No response Generated"` sentinel when no text survived) was produced; `failed` + `stop_reason=turn_capped` when nothing usable survived. `SubagentResult.stop_reason` flows through `task_tool.py::_task_result_command` → `format_subagent_result_message` (renders `Task Succeeded (capped: ...)` / `Task failed (capped: ...)`) and `make_subagent_additional_kwargs`, which stamps the additive `subagent_stop_reason` key alongside the normal `subagent_status`. **Why additive, not an enum**: a new status value would break v1 consumers; an optional field is ignored by older frontends and ledger readers, so the cross-language contract (`contracts/subagent_status_contract.json` v2 + `subagents/status_contract.py` + `frontend/.../subtask-result.ts`, pinned by `test_status_values_match_contract` / `test_stop_reason_values_match_contract`) stays backward-compatible. The durable delegation ledger captures `stop_reason` onto the entry and renders model-facing guidance ("hit a guardrail cap with a partial result; reuse it, retry tighter, or raise the per-agent budget (`max_turns` / `token_budget`)") so the lead reuses a capped completion knowingly instead of mistaking it for a clean one. (Phase 1 shipped this surfacing as a `MAX_TURNS_REACHED` status enum in #3949; Phase 2 replaced that enum with the additive `stop_reason` field per the agreed design — the `max_turns_reached` status value and `SubagentStatus.MAX_TURNS_REACHED` are gone.) +**Context compaction (#3875 Phase 3, #4039)**: subagents inherit `DeerFlowSummarizationMiddleware` via `build_subagent_runtime_middlewares`, gated on the **same** `summarization.enabled` switch the lead reads (one config covers both chains; trigger/keep/model/prompt come from the shared `summarization` config so they cannot drift). The subagent builder attaches `DurableContextMiddleware` immediately before summarization, using the same skills path/read-tool settings as the lead chain. Compaction stores the generated summary in `ThreadState.summary_text` rather than as a `messages` item; the durable-context wrapper therefore projects it into the next model request as guarded hidden human data. This is required when a message-count keep policy preserves only an assistant tool-call plus its tool results: without the injected summary the next request begins with assistant/tool history and strict OpenAI-compatible providers can reject it. Because `DurableContextMiddleware` inserts a second `SystemMessage(authority_contract)` after the subagent's leading system prompt, the builder also appends `SystemMessageCoalescingMiddleware` innermost (mirroring the lead chain, appended after the optional summarization middleware so it is unconditionally last) to merge every `SystemMessage` into one leading `system_message` — otherwise the durable fix would trade #4039's assistant-first HTTP 400 for a duplicate-system 400 on the same strict backends (#4040). The factory is called with `skip_memory_flush=True` on the subagent path: the lead's `memory_flush_hook` (attached when `memory.enabled`) flushes pre-compaction messages into durable memory keyed by `thread_id`, and subagents share the parent's `thread_id`, so without skipping the hook a subagent's internal turns would pollute the **parent** thread's durable memory. Placement differs from the lead chain (lead appends summarization *before* the guard trio; subagent appends it *after*) — benign because the middleware implements only `before_model` (compaction) with no `after_model`/`consume_stop_reason`, so it cannot disturb the Phase 2 guard-cap stop-reason channel. Compaction rewrites the messages channel via `RemoveMessage(id=REMOVE_ALL_MESSAGES)`, which shrinks `len(messages)` below the step-capture cursor mid-run; `capture_new_step_messages` (see Step capture below) resets the cursor to the new tail on contraction so steps appended after the compaction point are not silently dropped. +**Step capture & persistence (#3779)**: `executor.py` captures both assistant turns (`AIMessage`) **and** tool outputs (`ToolMessage`) via `subagents/step_events.py::capture_new_step_messages`, which walks the *newly-appended tail* of each `stream_mode="values"` chunk (not just `messages[-1]`) so a multi-tool-call turn — where LangGraph's `ToolNode` appends several `ToolMessage`s in one super-step — keeps every tool output instead of dropping all but the last. `runtime/runs/worker.py::_SubagentEventBuffer` additionally persists these `task_*` custom events to the `RunEventStore` as `subagent.start`/`subagent.step`/`subagent.end` (`category="subagent"`, `task_id` in `metadata`).

The dedicated category keeps them out of `list_messages` (the thread feed) while `list_events` returns them for the frontend's fetch-on-expand backfill. `list_events` accepts `task_id` (filters on `metadata["task_id"]` — SQL-side in `DbRunEventStore` via `event_metadata["task_id"].as_string()`, in-memory in the JSONL/memory stores) plus an `after_seq` forward cursor, so the card pages through one subagent's steps without the run-wide `limit` truncating the tail (no schema migration: the filter rides the existing run-scoped index). `step_events.py` is a pure, unit-tested layer (`build_subagent_step` / `subagent_run_event`). **History contraction (#3875 Phase 3)**: `capture_new_step_messages` assumes append-only growth, but `DeerFlowSummarizationMiddleware` rewrites the messages channel via `RemoveMessage(id=REMOVE_ALL_MESSAGES)`, shrinking `len(messages)` below the cursor mid-run. On contraction (`total < processed_count`) the cursor resets to the new tail; `capture_step_message`'s id/content dedup prevents re-emitting pre-compaction steps, so steps appended after the compaction point are still captured instead of being dropped until `total` overtakes the stale cursor. +**Deferred MCP tools** (if `tool_search.enabled`): `SubagentExecutor._build_initial_state` assembles deferral after policy filtering via the shared `assemble_deferred_tools` (fail-closed), appends the `tool_search` tool, injects the `` section into the subagent's `SystemMessage`, and threads the setup to `_create_agent`, which attaches `McpRoutingMiddleware` (when PR1 routing metadata matches deferred tools) before `DeferredToolFilterMiddleware` through `build_subagent_runtime_middlewares(...)`.

(1) *Slash*: the run's most recent `/skill` activation, persisted as a source on the run context (only the activated skill's **canonical container path**, never its declared secrets) so the whole tool loop after the activation call keeps the binding; a new activation replaces it. Slash reads the genuine user text via `get_original_user_content_text`; `InputSanitizationMiddleware` preserves it (`ORIGINAL_USER_CONTENT_KEY`), so activation fires even after sanitization. (2) *In-context* (autonomous invocation): skills the model actually loaded in this thread — `ThreadState.skill_context` entries. **Both sources resolve the live registry skill by normalized container path on every call** (`_resolve_registry_skill`) and bind only that skill's own declared secrets — enabled + allowlist checked for both; the `secrets-autonomous: false` opt-out (malformed values fail closed to `false`) additionally gates the in-context path but exempts explicit slash. Resolving by registry — not by trusting the source's stored data — is what makes a caller-forged `__slash_skill_secret_source` harmless (`runtime.context` is caller-mergeable; the gateway also strips caller `__`-keys in `build_run_config`), #3938. Authorization is three-gated regardless of activation style: skill **enabled** by the operator × values **supplied per-request** by the caller (`context.secrets`) × names **declared** in frontmatter (∩ semantics). Because the set is recomputed per call, a skill evicted from `skill_context` (capacity) or a caller that stops supplying a value loses injection on the next call. The injected value always comes from the caller's request, never the host environment (scrubbed first — see below), so a declared name that also exists in the host env is safe: the caller's value wins and the host value is dropped (the #3861 per-user-key-overrides-shared-key case). Missing required secrets are logged once per binding change, not injected; binding changes are recorded as a `middleware:skill_secrets` journal event (skill and secret names only, never values). - **Inject**: `bash_tool` reads the injection set and passes it as `execute_command(env=...)`.

Each agent owns its own thread; cross-agent coordination flows through GitHub (PR comments, review threads), the source of truth humans see. + +`ChannelStore` uses `topic_id = f"{number}:{agent_name}"` as its cache key, so each agent's cached mapping is independent — a coder's mapping is invisible to a reviewer on the same PR. + +## Mention-handle Precedence + +For bindings that declare `require_mention: true` on a given event, the dispatcher must resolve **which** mention login gates the trigger.

The `_is_self_event` gate uses the same precedence (with the agent's whole `bindings[*].triggers[*].mention_login` aggregated across all bindings, plus an `agent.name` fallback) so the self-loop gate and the mention gate stay coherent. + +## GH Token Lifecycle + +GitHub Agents get push/write credentials as **per-call installation tokens**, not as inherited environment.

A Python callable does not survive that serialization. The harness side (`_github_env_from_runtime`) already accepts either shape, but only `str` round-trips through the SDK transport. + +**Token TTL caveat**: GitHub installation tokens are valid for ~1 hour. Most agent runs finish well inside that window. Truly long coder runs (multi-hour refactors at the higher `recursion_limit=250` ceiling) may see a 401 on a late `git push` / `gh pr create`. Auto-refresh past the 1h TTL is intentionally deferred — it requires registering a token-provider lookup on the harness side, which crosses the harness/app boundary (`tests/test_harness_boundary.py`). Until refresh ships, long runs should finish GitHub writes before expiry or accept the loss. If minting fails (bad App id, wrong installation_id, missing private key), the agent still runs without push/write credentials — read-only is better than no response. + +## Thread-create Race Recovery + +Two webhook deliveries for the same `(repo, number)` can land within milliseconds of each other and race on `threads.create(thread_id=preferred_thread_id)`.

Any other failure (transient DB outage, network error, 5xx) propagates so the delivery can fail/retry rather than silently caching `preferred_thread_id` into the store and mapping every future webhook on this issue/PR to a thread that was never created (every later run would 404 forever with no retry path). + +The follow-up `threads.get(preferred_thread_id)` is itself verified before caching — if it also rejects, the store underneath is in an inconsistent state and the failure surfaces. + +## Outbound is Log-only + +```mermaid +graph LR + classDef agent fill:#E5D2C4,stroke:#806A5B,color:#30251E + classDef send fill:#C9D7D2,stroke:#5D706A,color:#21302C + classDef gh fill:#D7D3E8,stroke:#6B6680,color:#29263A + + Run["GitHub agent run"]:::agent + GhCLI["gh CLI

The platform worker consumes `/connect ` (Telegram uses `/start ` over a deep link) before applying any `allowed_users` filter, so a not-yet-allowlisted user can complete their first bind. +3. **Strict ownership transfer** — the latest successful bind wins; `upsert_connection` revokes other owners' active rows for the same external identity.

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.

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.

Since the limit is 3 per turn, I will launch the first 3 now, and the rest in the next turn.\\\"\\n\\n**Available Subagents:**\\n- **general-purpose**: For ANY non-trivial task - web research, code exploration, file operations, analysis, etc.\\n\\n**Your Orchestration Strategy:**\\n\\n\\u2705 **DECOMPOSE + PARALLEL EXECUTION (Preferred Approach):**\\n\\nFor complex queries, break them down into focused sub-tasks and execute in parallel batches (max 3 per turn):\\n\\n**Example 1: \\\"Why is Tencent's stock price declining?\\\" (3 sub-tasks \\u2192 1 batch)**\\n\\u2192 Turn 1: Launch 3 subagents in parallel:\\n- Subagent 1: Recent financial reports, earnings data, and revenue trends\\n- Subagent 2: Negative news, controversies, and regulatory issues\\n- Subagent 3: Industry trends, competitor performance, and market sentiment\\n\\u2192 Turn 2: Synthesize results\\n\\n**Example 2: \\\"Compare 5 cloud providers\\\" (5 sub-tasks \\u2192 multi-batch)**\\n\\u2192 Turn 1: Launch 3 subagents in parallel (first batch)\\n\\u2192 Turn 2: Launch remaining subagents in parallel\\n\\u2192 Final turn: Synthesize ALL results into comprehensive comparison\\n\\n**Example 3: \\\"Refactor the authentication system\\\"**\\n\\u2192 Turn 1: Launch 3 subagents in parallel:\\n- Subagent 1: Analyze current auth implementation and technical debt\\n- Subagent 2: Research best practices and security patterns\\n- Subagent 3: Review related tests, documentation, and vulnerabilities\\n\\u2192 Turn 2: Synthesize results\\n\\n\\u2705 **USE Parallel Subagents (max 3 per turn) when:**\\n- **Complex research questions**: Requires multiple information sources or perspectives\\n- **Multi-aspect analysis**: Task has several independent dimensions to explore\\n- **Large codebases**: Need to analyze different parts simultaneously\\n- **Comprehensive investigations**: Questions requiring thorough coverage from multiple angles\\n\\n\\u274c **DO NOT use subagents (execute directly) when:**\\n- **Task cannot be decomposed**: If you can't break it into 2+ meaningful parallel sub-tasks, execute directly\\n- **Ultra-simple actions**: Read one file, quick edits, single commands\\n- **Need immediate clarification**: Must ask user before proceeding\\n- **Meta conversation**: Questions about conversation history\\n- **Sequential dependencies**: Each step depends on previous results (do steps yourself sequentially)\\n\\n**CRITICAL WORKFLOW** (STRICTLY follow this before EVERY action):\\n1. **COUNT**: In your thinking, list all sub-tasks and count them explicitly: \\\"I have N sub-tasks\\\"\\n2. **PLAN BATCHES**: If N > 3, explicitly plan which sub-tasks go in which batch:\\n - \\\"Batch 1 (this turn): first 3 sub-tasks\\\"\\n - \\\"Batch 2 (next turn): next batch of sub-tasks\\\"\\n3. **EXECUTE**: Launch ONLY the current batch (max 3 `task` calls). Do NOT launch sub-tasks from future batches.\\n4. **REPEAT**: After results return, launch the next batch. Continue until all batches complete.\\n5. **SYNTHESIZE**: After ALL batches are done, synthesize all results.\\n6. **Cannot decompose** \\u2192 Execute directly using available tools (ls, read_file, web_search, etc.)\\n\\n**\\u26d4 VIOLATION: Launching more than 3 `task` calls in a single response is a HARD ERROR. The system WILL discard excess calls and you WILL lose work. Always batch.**\\n\\n**Remember: Subagents are for parallel decomposition, not for wrapping single tasks.**\\n\\n**How It Works:**\\n- The task tool runs subagents asynchronously in the background\\n- The backend automatically polls for completion (you don't need to poll)\\n- The tool call will block until the subagent completes its work\\n- Once complete, the result is returned to you directly\\n\\n**Usage Example 1 - Single Batch (\\u22643 sub-tasks):**\\n\\n```python\\n# User asks: \\\"Why is Tencent's stock price declining?\\\"\\n# Thinking: 3 sub-tasks \\u2192 fits in 1 batch\\n\\n# Turn 1: Launch 3 subagents in parallel\\ntask(description=\\\"Tencent financial data\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Tencent news & regulation\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Industry & market trends\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n# All 3 run in parallel \\u2192 synthesize results\\n```\\n\\n**Usage Example 2 - Multiple Batches (>3 sub-tasks):**\\n\\n```python\\n# User asks: \\\"Compare AWS, Azure, GCP, Alibaba Cloud, and Oracle Cloud\\\"\\n# Thinking: 5 sub-tasks \\u2192 need multiple batches (max 3 per batch)\\n\\n# Turn 1: Launch first batch of 3\\ntask(description=\\\"AWS analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Azure analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"GCP analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n\\n# Turn 2: Launch remaining batch (after first batch completes)\\ntask(description=\\\"Alibaba Cloud analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Oracle Cloud analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n\\n# Turn 3: Synthesize ALL results from both batches\\n```\\n\\n**Counter-Example - Direct Execution (NO subagents):**\\n\\n```python\\n# User asks: \\\"Read the README\\\"\\n# Thinking: Single straightforward file read\\n# \\u2192 Execute directly\\n\\nread_file(\\\"/mnt/user-data/workspace/README.md\\\") # Direct execution, not task()\\n```\\n\\n**CRITICAL**:\\n- **Max 3 `task` calls per turn** - the system enforces this, excess calls are discarded\\n- Only use `task` when you can launch 2+ subagents in parallel\\n- Single task = No value from subagents = Execute directly\\n- For >3 sub-tasks, use sequential batches of 3 across multiple turns\\n\\n\\n\\n- User uploads: `/mnt/user-data/uploads` - Files uploaded by the user (automatically listed in context)\\n- User workspace: `/mnt/user-data/workspace` - Working directory for temporary files\\n- Output files: `/mnt/user-data/outputs` - Final deliverables must be saved here\\n\\n**File Management:**\\n- Uploaded files are automatically listed in the section before each request\\n- Use `read_file` tool to read uploaded files using their paths from the list\\n- For PDF, PPT, Excel, and Word files, converted Markdown versions (*.md) are available alongside originals\\n- All temporary work happens in `/mnt/user-data/workspace`\\n- Treat `/mnt/user-data/workspace` as your default current working directory for coding and file-editing tasks\\n- When writing scripts or commands that create/read files from the workspace, prefer relative paths such as `hello.txt`, `../uploads/data.csv`, and `../outputs/report.md`\\n- Avoid hardcoding `/mnt/user-data/...` inside generated scripts when a relative path from the workspace is enough\\n- Final deliverables must be copied to `/mnt/user-data/outputs` and presented using `present_files` tool (\\u26a0\\ufe0f Skills are NOT deliverables \\u2014 use `skill_manage` tool instead)\\n\\n\\n\\n\\n- Clear and Concise: Avoid over-formatting unless requested\\n- Natural Tone: Use paragraphs and prose, not bullet points by default\\n- Action-Oriented: Focus on delivering results, not explaining processes\\n\\n\\n\\n**CRITICAL: Always include citations when using web search results**\\n\\n- **When to Use**: MANDATORY after web_search, web_fetch, or any external information source\\n- **Format**: Use Markdown link format `[citation:TITLE](URL)` immediately after the claim\\n- **Placement**: Inline citations should appear right after the sentence or claim they support\\n- **Sources Section**: Also collect all citations in a \\\"Sources\\\" section at the end of reports\\n\\n**Example -

When writing long new content from scratch, split it\\n into sections: the first `write_file` call creates the file, then use\\n `write_file` with append=True to extend it section by section. This\\n keeps each tool call small and avoids mid-stream chunk-gap timeouts\\n on oversized single-shot writes. (See issue #3189.) \\n- Clarity: Be direct and helpful, avoid unnecessary meta-commentary\\n- Including Images and Mermaid: Images and Mermaid diagrams are always welcomed in the Markdown format, and you're encouraged to use `![Image Description](image_path)\\n\\n` or \\\"```mermaid\\\" to display images in response or Markdown files\\n- Multi-task: Better utilize parallel tool calling to call multiple tools at one time for better performance\\n- Language Consistency: Keep using the same language as user's\\n- Always Respond: Your thinking is internal.

Your role is to be a **task orchestrator**:\\n1. **DECOMPOSE**: Break complex tasks into parallel sub-tasks\\n2. **DELEGATE**: Launch multiple subagents simultaneously using parallel `task` calls\\n3. **SYNTHESIZE**: Collect and integrate results into a coherent answer\\n\\n**CORE PRINCIPLE: Complex tasks should be decomposed and distributed across multiple subagents for parallel execution.**\\n\\n**\\u26d4 HARD CONCURRENCY LIMIT: MAXIMUM 3 `task` CALLS PER RESPONSE. THIS IS NOT OPTIONAL.**\\n- Each response, you may include **at most 3** `task` tool calls. Any excess calls are **silently discarded** by the system \\u2014 you will lose that work.\\n- **Before launching subagents, you MUST count your sub-tasks in your thinking:**\\n - If count \\u2264 3: Launch all in this response.\\n - If count > 3: **Pick the 3 most important/foundational sub-tasks for this turn.** Save the rest for the next turn.\\n- **Multi-batch execution** (for >3 sub-tasks):\\n - Turn 1: Launch sub-tasks 1-3 in parallel \\u2192 wait for results\\n - Turn 2: Launch next batch in parallel \\u2192 wait for results\\n - ... continue until all sub-tasks are complete\\n - Final turn: Synthesize ALL results into a coherent answer\\n- **Example thinking pattern**: \\\"I identified 6 sub-tasks. Since the limit is 3 per turn, I will launch the first 3 now, and the rest in the next turn.\\\"\\n\\n**Available Subagents:**\\n- **general-purpose**: For ANY non-trivial task - web research, code exploration, file operations, analysis, etc.\\n\\n**Your Orchestration Strategy:**\\n\\n\\u2705 **DECOMPOSE + PARALLEL EXECUTION (Preferred Approach):**\\n\\nFor complex queries, break them down into focused sub-tasks and execute in parallel batches (max 3 per turn):\\n\\n**Example 1: \\\"Why is Tencent's stock price declining?\\\" (3 sub-tasks \\u2192 1 batch)**\\n\\u2192 Turn 1: Launch 3 subagents in parallel:\\n- Subagent 1: Recent financial reports, earnings data, and revenue trends\\n- Subagent 2: Negative news, controversies, and regulatory issues\\n- Subagent 3: Industry trends, competitor performance, and market sentiment\\n\\u2192 Turn 2: Synthesize results\\n\\n**Example 2: \\\"Compare 5 cloud providers\\\" (5 sub-tasks \\u2192 multi-batch)**\\n\\u2192 Turn 1: Launch 3 subagents in parallel (first batch)\\n\\u2192 Turn 2: Launch remaining subagents in parallel\\n\\u2192 Final turn: Synthesize ALL results into comprehensive comparison\\n\\n**Example 3: \\\"Refactor the authentication system\\\"**\\n\\u2192 Turn 1: Launch 3 subagents in parallel:\\n- Subagent 1: Analyze current auth implementation and technical debt\\n- Subagent 2: Research best practices and security patterns\\n- Subagent 3: Review related tests, documentation, and vulnerabilities\\n\\u2192 Turn 2: Synthesize results\\n\\n\\u2705 **USE Parallel Subagents (max 3 per turn) when:**\\n- **Complex research questions**: Requires multiple information sources or perspectives\\n- **Multi-aspect analysis**: Task has several independent dimensions to explore\\n- **Large codebases**: Need to analyze different parts simultaneously\\n- **Comprehensive investigations**: Questions requiring thorough coverage from multiple angles\\n\\n\\u274c **DO NOT use subagents (execute directly) when:**\\n- **Task cannot be decomposed**: If you can't break it into 2+ meaningful parallel sub-tasks, execute directly\\n- **Ultra-simple actions**: Read one file, quick edits, single commands\\n- **Need immediate clarification**: Must ask user before proceeding\\n- **Meta conversation**: Questions about conversation history\\n- **Sequential dependencies**: Each step depends on previous results (do steps yourself sequentially)\\n\\n**CRITICAL WORKFLOW** (STRICTLY follow this before EVERY action):\\n1. **COUNT**: In your thinking, list all sub-tasks and count them explicitly: \\\"I have N sub-tasks\\\"\\n2. **PLAN BATCHES**: If N > 3, explicitly plan which sub-tasks go in which batch:\\n - \\\"Batch 1 (this turn): first 3 sub-tasks\\\"\\n - \\\"Batch 2 (next turn): next batch of sub-tasks\\\"\\n3. **EXECUTE**: Launch ONLY the current batch (max 3 `task` calls). Do NOT launch sub-tasks from future batches.\\n4. **REPEAT**: After results return, launch the next batch. Continue until all batches complete.\\n5. **SYNTHESIZE**: After ALL batches are done, synthesize all results.\\n6. **Cannot decompose** \\u2192 Execute directly using available tools (ls, read_file, web_search, etc.)\\n\\n**\\u26d4 VIOLATION: Launching more than 3 `task` calls in a single response is a HARD ERROR. The system WILL discard excess calls and you WILL lose work. Always batch.**\\n\\n**Remember: Subagents are for parallel decomposition, not for wrapping single tasks.**\\n\\n**How It Works:**\\n- The task tool runs subagents asynchronously in the background\\n- The backend automatically polls for completion (you don't need to poll)\\n- The tool call will block until the subagent completes its work\\n- Once complete, the result is returned to you directly\\n\\n**Usage Example 1 - Single Batch (\\u22643 sub-tasks):**\\n\\n```python\\n# User asks: \\\"Why is Tencent's stock price declining?\\\"\\n# Thinking: 3 sub-tasks \\u2192 fits in 1 batch\\n\\n# Turn 1: Launch 3 subagents in parallel\\ntask(description=\\\"Tencent financial data\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Tencent news & regulation\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Industry & market trends\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n# All 3 run in parallel \\u2192 synthesize results\\n```\\n\\n**Usage Example 2 - Multiple Batches (>3 sub-tasks):**\\n\\n```python\\n# User asks: \\\"Compare AWS, Azure, GCP, Alibaba Cloud, and Oracle Cloud\\\"\\n# Thinking: 5 sub-tasks \\u2192 need multiple batches (max 3 per batch)\\n\\n# Turn 1: Launch first batch of 3\\ntask(description=\\\"AWS analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Azure analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"GCP analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n\\n# Turn 2: Launch remaining batch (after first batch completes)\\ntask(description=\\\"Alibaba Cloud analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Oracle Cloud analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n\\n# Turn 3: Synthesize ALL results from both batches\\n```\\n\\n**Counter-Example - Direct Execution (NO subagents):**\\n\\n```python\\n# User asks: \\\"Read the README\\\"\\n# Thinking: Single straightforward file read\\n# \\u2192 Execute directly\\n\\nread_file(\\\"/mnt/user-data/workspace/README.md\\\") # Direct execution, not task()\\n```\\n\\n**CRITICAL**:\\n- **Max 3 `task` calls per turn** - the system enforces this, excess calls are discarded\\n- Only use `task` when you can launch 2+ subagents in parallel\\n- Single task = No value from subagents = Execute directly\\n- For >3 sub-tasks, use sequential batches of 3 across multiple turns\\n\\n\\n\\n- User uploads: `/mnt/user-data/uploads` - Files uploaded by the user (automatically listed in context)\\n- User workspace: `/mnt/user-data/workspace` - Working directory for temporary files\\n- Output files: `/mnt/user-data/outputs` - Final deliverables must be saved here\\n\\n**File Management:**\\n- Uploaded files are automatically listed in the section before each request\\n- Use `read_file` tool to read uploaded files using their paths from the list\\n- For PDF, PPT, Excel, and Word files, converted Markdown versions (*.md) are available alongside originals\\n- All temporary work happens in `/mnt/user-data/workspace`\\n- Treat `/mnt/user-data/workspace` as your default current working directory for coding and file-editing tasks\\n- When writing scripts or commands that create/read files from the workspace, prefer relative paths such as `hello.txt`, `../uploads/data.csv`, and `../outputs/report.md`\\n- Avoid hardcoding `/mnt/user-data/...` inside generated scripts when a relative path from the workspace is enough\\n- Final deliverables must be copied to `/mnt/user-data/outputs` and presented using `present_files` tool (\\u26a0\\ufe0f Skills are NOT deliverables \\u2014 use `skill_manage` tool instead)\\n\\n\\n\\n\\n- Clear and Concise: Avoid over-formatting unless requested\\n- Natural Tone: Use paragraphs and prose, not bullet points by default\\n- Action-Oriented: Focus on delivering results, not explaining processes\\n\\n\\n\\n**CRITICAL: Always include citations when using web search results**\\n\\n- **When to Use**: MANDATORY after web_search, web_fetch, or any external information source\\n- **Format**: Use Markdown link format `[citation:TITLE](URL)` immediately after the claim\\n- **Placement**: Inline citations should appear right after the sentence or claim they support\\n- **Sources Section**: Also collect all citations in a \\\"Sources\\\" section at the end of reports\\n\\n**Example - Inline Citations:**\\n```markdown\\nThe key AI trends for 2026 include enhanced reasoning capabilities and multimodal integration\\n[citation:AI Trends 2026](https://techcrunch.com/ai-trends).\\nRecent breakthroughs in language models have also accelerated progress\\n[citation:OpenAI Research](https://openai.com/research).\\n```\\n\\n**Example -

Use web_search to find sources \\u2192 Extract {title, url, snippet} from results\\n2. Write content with inline citations: `claim [citation:Title](url)`\\n3. Collect all citations in a \\\"Sources\\\" section at the end\\n4. NEVER write claims without citations when sources are available\\n\\n**CRITICAL RULES:**\\n- \\u274c DO NOT write research content without citations\\n- \\u274c DO NOT forget to extract URLs from search results\\n- \\u2705 ALWAYS add `[citation:Title](URL)` after claims from external sources\\n- \\u2705 ALWAYS include a \\\"Sources\\\" section listing all references\\n\\n\\n\\n- **Clarification First**: ALWAYS clarify unclear/missing/ambiguous requirements BEFORE starting work - never assume or guess\\n- **Orchestrator Mode**: You are a task orchestrator - decompose complex tasks into parallel sub-tasks. **HARD LIMIT: max 3 `task` calls per response.** If >3 sub-tasks, split into sequential batches of \\u22643. Synthesize after ALL batches complete.\\n- Skill First: Always load the relevant skill before starting **complex** tasks.\\n\\n- Progressive Loading: Load skill resources incrementally as referenced\\n- Output Files: Final deliverables must be in `/mnt/user-data/outputs` (\\u26a0\\ufe0f Skills are NOT deliverables \\u2014 use `skill_manage` tool instead)\\n- File Editing Workflow: When revising an existing file, prefer\\n `str_replace` over `write_file` \\u2014 it sends only the diff and avoids\\n re-emitting the whole file (mirrors Claude Code's Edit and Codex's\\n apply_patch). When writing long new content from scratch, split it\\n into sections: the first `write_file` call creates the file, then use\\n `write_file` with append=True to extend it section by section. This\\n keeps each tool call small and avoids mid-stream chunk-gap timeouts\\n on oversized single-shot writes. (See issue #3189.) \\n- Clarity: Be direct and helpful, avoid unnecessary meta-commentary\\n- Including Images and Mermaid: Images and Mermaid diagrams are always welcomed in the Markdown format, and you're encouraged to use `![Image Description](image_path)\\n\\n` or \\\"```mermaid\\\" to display images in response or Markdown files\\n- Multi-task: Better utilize parallel tool calling to call multiple tools at one time for better performance\\n- Language Consistency: Keep using the same language as user's\\n- Always Respond: Your thinking is internal.

When a user query matches a skill's use case, immediately call `read_file` on the skill's main file using the path attribute provided in the skill tag below\\n2. Read and understand the skill's workflow and instructions\\n3. The skill file contains references to external resources under the same folder\\n4. Load referenced resources only when needed during execution\\n5. Follow the skill's instructions precisely\\n\\n**Explicit Slash Skill Activation:**\\n- If the user starts a request with `/`, that skill was explicitly requested for the current turn.\\n- Follow the activated skill before choosing a general workflow.\\n- The runtime injects the activated skill content for explicit slash activations; do not call `read_file` for that SKILL.md again unless the injected skill references supporting resources you need.\\n\\n**Skills are located at:** /mnt/skills\\n\\n\\n \\n academic-paper-review\\n Use this skill when the user requests to review, analyze, critique, or summarize academic papers, research articles, preprints, or scientific publications.

Your role is to be a **task orchestrator**:\\n1. **DECOMPOSE**: Break complex tasks into parallel sub-tasks\\n2. **DELEGATE**: Launch multiple subagents simultaneously using parallel `task` calls\\n3. **SYNTHESIZE**: Collect and integrate results into a coherent answer\\n\\n**CORE PRINCIPLE: Complex tasks should be decomposed and distributed across multiple subagents for parallel execution.**\\n\\n**\\u26d4 HARD CONCURRENCY LIMIT: MAXIMUM 3 `task` CALLS PER RESPONSE. THIS IS NOT OPTIONAL.**\\n- Each response, you may include **at most 3** `task` tool calls. Any excess calls are **silently discarded** by the system \\u2014 you will lose that work.\\n- **Before launching subagents, you MUST count your sub-tasks in your thinking:**\\n - If count \\u2264 3: Launch all in this response.\\n - If count > 3: **Pick the 3 most important/foundational sub-tasks for this turn.** Save the rest for the next turn.\\n- **Multi-batch execution** (for >3 sub-tasks):\\n - Turn 1: Launch sub-tasks 1-3 in parallel \\u2192 wait for results\\n - Turn 2: Launch next batch in parallel \\u2192 wait for results\\n - ... continue until all sub-tasks are complete\\n - Final turn: Synthesize ALL results into a coherent answer\\n- **Example thinking pattern**: \\\"I identified 6 sub-tasks. Since the limit is 3 per turn, I will launch the first 3 now, and the rest in the next turn.\\\"\\n\\n**Available Subagents:**\\n- **general-purpose**: For ANY non-trivial task - web research, code exploration, file operations, analysis, etc.\\n\\n**Your Orchestration Strategy:**\\n\\n\\u2705 **DECOMPOSE + PARALLEL EXECUTION (Preferred Approach):**\\n\\nFor complex queries, break them down into focused sub-tasks and execute in parallel batches (max 3 per turn):\\n\\n**Example 1: \\\"Why is Tencent's stock price declining?\\\" (3 sub-tasks \\u2192 1 batch)**\\n\\u2192 Turn 1: Launch 3 subagents in parallel:\\n- Subagent 1: Recent financial reports, earnings data, and revenue trends\\n- Subagent 2: Negative news, controversies, and regulatory issues\\n- Subagent 3: Industry trends, competitor performance, and market sentiment\\n\\u2192 Turn 2: Synthesize results\\n\\n**Example 2: \\\"Compare 5 cloud providers\\\" (5 sub-tasks \\u2192 multi-batch)**\\n\\u2192 Turn 1: Launch 3 subagents in parallel (first batch)\\n\\u2192 Turn 2: Launch remaining subagents in parallel\\n\\u2192 Final turn: Synthesize ALL results into comprehensive comparison\\n\\n**Example 3: \\\"Refactor the authentication system\\\"**\\n\\u2192 Turn 1: Launch 3 subagents in parallel:\\n- Subagent 1: Analyze current auth implementation and technical debt\\n- Subagent 2: Research best practices and security patterns\\n- Subagent 3: Review related tests, documentation, and vulnerabilities\\n\\u2192 Turn 2: Synthesize results\\n\\n\\u2705 **USE Parallel Subagents (max 3 per turn) when:**\\n- **Complex research questions**: Requires multiple information sources or perspectives\\n- **Multi-aspect analysis**: Task has several independent dimensions to explore\\n- **Large codebases**: Need to analyze different parts simultaneously\\n- **Comprehensive investigations**: Questions requiring thorough coverage from multiple angles\\n\\n\\u274c **DO NOT use subagents (execute directly) when:**\\n- **Task cannot be decomposed**: If you can't break it into 2+ meaningful parallel sub-tasks, execute directly\\n- **Ultra-simple actions**: Read one file, quick edits, single commands\\n- **Need immediate clarification**: Must ask user before proceeding\\n- **Meta conversation**: Questions about conversation history\\n- **Sequential dependencies**: Each step depends on previous results (do steps yourself sequentially)\\n\\n**CRITICAL WORKFLOW** (STRICTLY follow this before EVERY action):\\n1. **COUNT**: In your thinking, list all sub-tasks and count them explicitly: \\\"I have N sub-tasks\\\"\\n2. **PLAN BATCHES**: If N > 3, explicitly plan which sub-tasks go in which batch:\\n - \\\"Batch 1 (this turn): first 3 sub-tasks\\\"\\n - \\\"Batch 2 (next turn): next batch of sub-tasks\\\"\\n3. **EXECUTE**: Launch ONLY the current batch (max 3 `task` calls). Do NOT launch sub-tasks from future batches.\\n4. **REPEAT**: After results return, launch the next batch. Continue until all batches complete.\\n5. **SYNTHESIZE**: After ALL batches are done, synthesize all results.\\n6. **Cannot decompose** \\u2192 Execute directly using available tools (ls, read_file, web_search, etc.)\\n\\n**\\u26d4 VIOLATION: Launching more than 3 `task` calls in a single response is a HARD ERROR. The system WILL discard excess calls and you WILL lose work. Always batch.**\\n\\n**Remember: Subagents are for parallel decomposition, not for wrapping single tasks.**\\n\\n**How It Works:**\\n- The task tool runs subagents asynchronously in the background\\n- The backend automatically polls for completion (you don't need to poll)\\n- The tool call will block until the subagent completes its work\\n- Once complete, the result is returned to you directly\\n\\n**Usage Example 1 - Single Batch (\\u22643 sub-tasks):**\\n\\n```python\\n# User asks: \\\"Why is Tencent's stock price declining?\\\"\\n# Thinking: 3 sub-tasks \\u2192 fits in 1 batch\\n\\n# Turn 1: Launch 3 subagents in parallel\\ntask(description=\\\"Tencent financial data\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Tencent news & regulation\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Industry & market trends\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n# All 3 run in parallel \\u2192 synthesize results\\n```\\n\\n**Usage Example 2 - Multiple Batches (>3 sub-tasks):**\\n\\n```python\\n# User asks: \\\"Compare AWS, Azure, GCP, Alibaba Cloud, and Oracle Cloud\\\"\\n# Thinking: 5 sub-tasks \\u2192 need multiple batches (max 3 per batch)\\n\\n# Turn 1: Launch first batch of 3\\ntask(description=\\\"AWS analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Azure analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"GCP analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n\\n# Turn 2: Launch remaining batch (after first batch completes)\\ntask(description=\\\"Alibaba Cloud analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Oracle Cloud analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n\\n# Turn 3: Synthesize ALL results from both batches\\n```\\n\\n**Counter-Example - Direct Execution (NO subagents):**\\n\\n```python\\n# User asks: \\\"Read the README\\\"\\n# Thinking: Single straightforward file read\\n# \\u2192 Execute directly\\n\\nread_file(\\\"/mnt/user-data/workspace/README.md\\\") # Direct execution, not task()\\n```\\n\\n**CRITICAL**:\\n- **Max 3 `task` calls per turn** - the system enforces this, excess calls are discarded\\n- Only use `task` when you can launch 2+ subagents in parallel\\n- Single task = No value from subagents = Execute directly\\n- For >3 sub-tasks, use sequential batches of 3 across multiple turns\\n\\n\\n\\n- User uploads: `/mnt/user-data/uploads` - Files uploaded by the user (automatically listed in context)\\n- User workspace: `/mnt/user-data/workspace` - Working directory for temporary files\\n- Output files: `/mnt/user-data/outputs` - Final deliverables must be saved here\\n\\n**File Management:**\\n- Uploaded files are automatically listed in the section before each request\\n- Use `read_file` tool to read uploaded files using their paths from the list\\n- For PDF, PPT, Excel, and Word files, converted Markdown versions (*.md) are available alongside originals\\n- All temporary work happens in `/mnt/user-data/workspace`\\n- Treat `/mnt/user-data/workspace` as your default current working directory for coding and file-editing tasks\\n- When writing scripts or commands that create/read files from the workspace, prefer relative paths such as `hello.txt`, `../uploads/data.csv`, and `../outputs/report.md`\\n- Avoid hardcoding `/mnt/user-data/...` inside generated scripts when a relative path from the workspace is enough\\n- Final deliverables must be copied to `/mnt/user-data/outputs` and presented using `present_files` tool (\\u26a0\\ufe0f Skills are NOT deliverables \\u2014 use `skill_manage` tool instead)\\n\\n\\n\\n\\n- Clear and Concise: Avoid over-formatting unless requested\\n- Natural Tone: Use paragraphs and prose, not bullet points by default\\n- Action-Oriented: Focus on delivering results, not explaining processes\\n\\n\\n\\n**CRITICAL: Always include citations when using web search results**\\n\\n- **When to Use**: MANDATORY after web_search, web_fetch, or any external information source\\n- **Format**: Use Markdown link format `[citation:TITLE](URL)` immediately after the claim\\n- **Placement**: Inline citations should appear right after the sentence or claim they support\\n- **Sources Section**: Also collect all citations in a \\\"Sources\\\" section at the end of reports\\n\\n**Example - Inline Citations:**\\n```markdown\\nThe key AI trends for 2026 include enhanced reasoning capabilities and multimodal integration\\n[citation:AI Trends 2026](https://techcrunch.com/ai-trends).\\nRecent breakthroughs in language models have also accelerated progress\\n[citation:OpenAI Research](https://openai.com/research).\\n```\\n\\n**Example -

Use web_search to find sources \\u2192 Extract {title, url, snippet} from results\\n2. Write content with inline citations: `claim [citation:Title](url)`\\n3. Collect all citations in a \\\"Sources\\\" section at the end\\n4. NEVER write claims without citations when sources are available\\n\\n**CRITICAL RULES:**\\n- \\u274c DO NOT write research content without citations\\n- \\u274c DO NOT forget to extract URLs from search results\\n- \\u2705 ALWAYS add `[citation:Title](URL)` after claims from external sources\\n- \\u2705 ALWAYS include a \\\"Sources\\\" section listing all references\\n\\n\\n\\n- **Clarification First**: ALWAYS clarify unclear/missing/ambiguous requirements BEFORE starting work - never assume or guess\\n- **Orchestrator Mode**: You are a task orchestrator - decompose complex tasks into parallel sub-tasks. **HARD LIMIT: max 3 `task` calls per response.** If >3 sub-tasks, split into sequential batches of \\u22643. Synthesize after ALL batches complete.\\n- Skill First: Always load the relevant skill before starting **complex** tasks.\\n\\n- Progressive Loading: Load skill resources incrementally as referenced\\n- Output Files: Final deliverables must be in `/mnt/user-data/outputs` (\\u26a0\\ufe0f Skills are NOT deliverables \\u2014 use `skill_manage` tool instead)\\n- File Editing Workflow: When revising an existing file, prefer\\n `str_replace` over `write_file` \\u2014 it sends only the diff and avoids\\n re-emitting the whole file (mirrors Claude Code's Edit and Codex's\\n apply_patch). When writing long new content from scratch, split it\\n into sections: the first `write_file` call creates the file, then use\\n `write_file` with append=True to extend it section by section. This\\n keeps each tool call small and avoids mid-stream chunk-gap timeouts\\n on oversized single-shot writes. (See issue #3189.) \\n- Clarity: Be direct and helpful, avoid unnecessary meta-commentary\\n- Including Images and Mermaid: Images and Mermaid diagrams are always welcomed in the Markdown format, and you're encouraged to use `![Image Description](image_path)\\n\\n` or \\\"```mermaid\\\" to display images in response or Markdown files\\n- Multi-task: Better utilize parallel tool calling to call multiple tools at one time for better performance\\n- Language Consistency: Keep using the same language as user's\\n- Always Respond: Your thinking is internal. You MUST always provide a visible response to the user after thinking.\\n\\n\\n\\n\\n2026-07-09, Thursday\\n\"}", + "{\"human\": \"--- BEGIN USER INPUT ---\\nResearch the current state of solid-state EV batteries in 2025 and write a 1-page markdown briefing with sources.\\n--- END USER INPUT ---\"}", + "{\"ai\": \"[{\\\"name\\\": \\\"web_search\\\", \\\"args\\\": {\\\"query\\\": \\\"solid-state EV batteries 2025\\\"}, \\\"id\\\": \\\"call_e9OloaPirm6u3bFXXODEQP0L\\\", \\\"type\\\": \\\"tool_call\\\"}]\"}", + "{\"tool\": \"{\\n \\\"query\\\": \\\"solid-state EV batteries 2025\\\",\\n \\\"total_results\\\": 5,\\n \\\"results\\\": [\\n {\\n \\\"title\\\": \\\"Solid-state battery technology\\\",\\n \\\"url\\\": \\\"https://www.evinfrastructurenews.com/ev-battery/solid-state-battery-technology\\\",\\n \\\"content\\\": \\\"March 10, 2026 - One of Toyota\\u2019s latest patents (20260024805) from 2025 centres on ensuring that solid-state batteries can be manufactured in the factory while controlling lamination and pressing methods to prevent moisture and contamination in the battery.\\\"\\n },\\n {\\n \\\"title\\\": \\\"All Current And Upcoming EVs With Solid-State Batteries\\\",\\n \\\"url\\\": \\\"https://insideevs.com/news/771402/every-solid-state-battery-ev/\\\",\\n \\\"content\\\": \\\"January 5, 2026 - Update: The first product of the Volkswagen\\u2013QuantumScape partnership may not be an electric car at all, but a motorcycle.

Your role is to be a **task orchestrator**:\\n1. **DECOMPOSE**: Break complex tasks into parallel sub-tasks\\n2. **DELEGATE**: Launch multiple subagents simultaneously using parallel `task` calls\\n3. **SYNTHESIZE**: Collect and integrate results into a coherent answer\\n\\n**CORE PRINCIPLE: Complex tasks should be decomposed and distributed across multiple subagents for parallel execution.**\\n\\n**\\u26d4 HARD CONCURRENCY LIMIT: MAXIMUM 3 `task` CALLS PER RESPONSE. THIS IS NOT OPTIONAL.**\\n- Each response, you may include **at most 3** `task` tool calls. Any excess calls are **silently discarded** by the system \\u2014 you will lose that work.\\n- **Before launching subagents, you MUST count your sub-tasks in your thinking:**\\n - If count \\u2264 3: Launch all in this response.\\n - If count > 3: **Pick the 3 most important/foundational sub-tasks for this turn.** Save the rest for the next turn.\\n- **Multi-batch execution** (for >3 sub-tasks):\\n - Turn 1: Launch sub-tasks 1-3 in parallel \\u2192 wait for results\\n - Turn 2: Launch next batch in parallel \\u2192 wait for results\\n - ... continue until all sub-tasks are complete\\n - Final turn: Synthesize ALL results into a coherent answer\\n- **Example thinking pattern**: \\\"I identified 6 sub-tasks. Since the limit is 3 per turn, I will launch the first 3 now, and the rest in the next turn.\\\"\\n\\n**Available Subagents:**\\n- **general-purpose**: For ANY non-trivial task - web research, code exploration, file operations, analysis, etc.\\n\\n**Your Orchestration Strategy:**\\n\\n\\u2705 **DECOMPOSE + PARALLEL EXECUTION (Preferred Approach):**\\n\\nFor complex queries, break them down into focused sub-tasks and execute in parallel batches (max 3 per turn):\\n\\n**Example 1: \\\"Why is Tencent's stock price declining?\\\" (3 sub-tasks \\u2192 1 batch)**\\n\\u2192 Turn 1: Launch 3 subagents in parallel:\\n- Subagent 1: Recent financial reports, earnings data, and revenue trends\\n- Subagent 2: Negative news, controversies, and regulatory issues\\n- Subagent 3: Industry trends, competitor performance, and market sentiment\\n\\u2192 Turn 2: Synthesize results\\n\\n**Example 2: \\\"Compare 5 cloud providers\\\" (5 sub-tasks \\u2192 multi-batch)**\\n\\u2192 Turn 1: Launch 3 subagents in parallel (first batch)\\n\\u2192 Turn 2: Launch remaining subagents in parallel\\n\\u2192 Final turn: Synthesize ALL results into comprehensive comparison\\n\\n**Example 3: \\\"Refactor the authentication system\\\"**\\n\\u2192 Turn 1: Launch 3 subagents in parallel:\\n- Subagent 1: Analyze current auth implementation and technical debt\\n- Subagent 2: Research best practices and security patterns\\n- Subagent 3: Review related tests, documentation, and vulnerabilities\\n\\u2192 Turn 2: Synthesize results\\n\\n\\u2705 **USE Parallel Subagents (max 3 per turn) when:**\\n- **Complex research questions**: Requires multiple information sources or perspectives\\n- **Multi-aspect analysis**: Task has several independent dimensions to explore\\n- **Large codebases**: Need to analyze different parts simultaneously\\n- **Comprehensive investigations**: Questions requiring thorough coverage from multiple angles\\n\\n\\u274c **DO NOT use subagents (execute directly) when:**\\n- **Task cannot be decomposed**: If you can't break it into 2+ meaningful parallel sub-tasks, execute directly\\n- **Ultra-simple actions**: Read one file, quick edits, single commands\\n- **Need immediate clarification**: Must ask user before proceeding\\n- **Meta conversation**: Questions about conversation history\\n- **Sequential dependencies**: Each step depends on previous results (do steps yourself sequentially)\\n\\n**CRITICAL WORKFLOW** (STRICTLY follow this before EVERY action):\\n1. **COUNT**: In your thinking, list all sub-tasks and count them explicitly: \\\"I have N sub-tasks\\\"\\n2. **PLAN BATCHES**: If N > 3, explicitly plan which sub-tasks go in which batch:\\n - \\\"Batch 1 (this turn): first 3 sub-tasks\\\"\\n - \\\"Batch 2 (next turn): next batch of sub-tasks\\\"\\n3. **EXECUTE**: Launch ONLY the current batch (max 3 `task` calls). Do NOT launch sub-tasks from future batches.\\n4. **REPEAT**: After results return, launch the next batch. Continue until all batches complete.\\n5. **SYNTHESIZE**: After ALL batches are done, synthesize all results.\\n6. **Cannot decompose** \\u2192 Execute directly using available tools (ls, read_file, web_search, etc.)\\n\\n**\\u26d4 VIOLATION: Launching more than 3 `task` calls in a single response is a HARD ERROR. The system WILL discard excess calls and you WILL lose work. Always batch.**\\n\\n**Remember: Subagents are for parallel decomposition, not for wrapping single tasks.**\\n\\n**How It Works:**\\n- The task tool runs subagents asynchronously in the background\\n- The backend automatically polls for completion (you don't need to poll)\\n- The tool call will block until the subagent completes its work\\n- Once complete, the result is returned to you directly\\n\\n**Usage Example 1 - Single Batch (\\u22643 sub-tasks):**\\n\\n```python\\n# User asks: \\\"Why is Tencent's stock price declining?\\\"\\n# Thinking: 3 sub-tasks \\u2192 fits in 1 batch\\n\\n# Turn 1: Launch 3 subagents in parallel\\ntask(description=\\\"Tencent financial data\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Tencent news & regulation\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Industry & market trends\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n# All 3 run in parallel \\u2192 synthesize results\\n```\\n\\n**Usage Example 2 - Multiple Batches (>3 sub-tasks):**\\n\\n```python\\n# User asks: \\\"Compare AWS, Azure, GCP, Alibaba Cloud, and Oracle Cloud\\\"\\n# Thinking: 5 sub-tasks \\u2192 need multiple batches (max 3 per batch)\\n\\n# Turn 1: Launch first batch of 3\\ntask(description=\\\"AWS analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Azure analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"GCP analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n\\n# Turn 2: Launch remaining batch (after first batch completes)\\ntask(description=\\\"Alibaba Cloud analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\ntask(description=\\\"Oracle Cloud analysis\\\", prompt=\\\"...\\\", subagent_type=\\\"general-purpose\\\")\\n\\n# Turn 3: Synthesize ALL results from both batches\\n```\\n\\n**Counter-Example -

the system enforces this, excess calls are discarded\\n- Only use `task` when you can launch 2+ subagents in parallel\\n- Single task = No value from subagents = Execute directly\\n- For >3 sub-tasks, use sequential batches of 3 across multiple turns\\n\\n\\n\\n- User uploads: `/mnt/user-data/uploads` - Files uploaded by the user (automatically listed in context)\\n- User workspace: `/mnt/user-data/workspace` - Working directory for temporary files\\n- Output files: `/mnt/user-data/outputs` - Final deliverables must be saved here\\n\\n**File Management:**\\n- Uploaded files are automatically listed in the section before each request\\n- Use `read_file` tool to read uploaded files using their paths from the list\\n- For PDF, PPT, Excel, and Word files, converted Markdown versions (*.md) are available alongside originals\\n- All temporary work happens in `/mnt/user-data/workspace`\\n- Treat `/mnt/user-data/workspace` as your default current working directory for coding and file-editing tasks\\n- When writing scripts or commands that create/read files from the workspace, prefer relative paths such as `hello.txt`, `../uploads/data.csv`, and `../outputs/report.md`\\n- Avoid hardcoding `/mnt/user-data/...` inside generated scripts when a relative path from the workspace is enough\\n- Final deliverables must be copied to `/mnt/user-data/outputs` and presented using `present_files` tool (\\u26a0\\ufe0f Skills are NOT deliverables \\u2014 use `skill_manage` tool instead)\\n\\n\\n\\n\\n- Clear and Concise: Avoid over-formatting unless requested\\n- Natural Tone: Use paragraphs and prose, not bullet points by default\\n- Action-Oriented: Focus on delivering results, not explaining processes\\n\\n\\n\\n**CRITICAL: Always include citations when using web search results**\\n\\n- **When to Use**: MANDATORY after web_search, web_fetch, or any external information source\\n- **Format**: Use Markdown link format `[citation:TITLE](URL)` immediately after the claim\\n- **Placement**: Inline citations should appear right after the sentence or claim they support\\n- **Sources Section**: Also collect all citations in a \\\"Sources\\\" section at the end of reports\\n\\n**Example -

Use web_search to find sources \\u2192 Extract {title, url, snippet} from results\\n2. Write content with inline citations: `claim [citation:Title](url)`\\n3. Collect all citations in a \\\"Sources\\\" section at the end\\n4. NEVER write claims without citations when sources are available\\n\\n**CRITICAL RULES:**\\n- \\u274c DO NOT write research content without citations\\n- \\u274c DO NOT forget to extract URLs from search results\\n- \\u2705 ALWAYS add `[citation:Title](URL)` after claims from external sources\\n- \\u2705 ALWAYS include a \\\"Sources\\\" section listing all references\\n\\n\\n\\n- **Clarification First**: ALWAYS clarify unclear/missing/ambiguous requirements BEFORE starting work - never assume or guess\\n- **Orchestrator Mode**: You are a task orchestrator - decompose complex tasks into parallel sub-tasks. **HARD LIMIT: max 3 `task` calls per response.** If >3 sub-tasks, split into sequential batches of \\u22643. Synthesize after ALL batches complete.\\n- Skill First: Always load the relevant skill before starting **complex** tasks.\\n\\n- Progressive Loading: Load skill resources incrementally as referenced\\n- Output Files: Final deliverables must be in `/mnt/user-data/outputs` (\\u26a0\\ufe0f Skills are NOT deliverables \\u2014 use `skill_manage` tool instead)\\n- File Editing Workflow: When revising an existing file, prefer\\n `str_replace` over `write_file` \\u2014 it sends only the diff and avoids\\n re-emitting the whole file (mirrors Claude Code's Edit and Codex's\\n apply_patch). When writing long new content from scratch, split it\\n into sections: the first `write_file` call creates the file, then use\\n `write_file` with append=True to extend it section by section. This\\n keeps each tool call small and avoids mid-stream chunk-gap timeouts\\n on oversized single-shot writes. (See issue #3189.) \\n- Clarity: Be direct and helpful, avoid unnecessary meta-commentary\\n- Including Images and Mermaid: Images and Mermaid diagrams are always welcomed in the Markdown format, and you're encouraged to use `![Image Description](image_path)\\n\\n` or \\\"```mermaid\\\" to display images in response or Markdown files\\n- Multi-task: Better utilize parallel tool calling to call multiple tools at one time for better performance\\n- Language Consistency: Keep using the same language as user's\\n- Always Respond: Your thinking is internal. You MUST always provide a visible response to the user after thinking.\\n\\n\\n\\n\\n2026-07-09, Thursday\\n\"}", + "{\"human\": \"--- BEGIN USER INPUT ---\\nResearch the current state of solid-state EV batteries in 2025 and write a 1-page markdown briefing with sources.\\n--- END USER INPUT ---\"}", + "{\"ai\": \"[{\\\"name\\\": \\\"web_search\\\", \\\"args\\\": {\\\"query\\\": \\\"solid-state EV batteries 2025\\\"}, \\\"id\\\": \\\"call_e9OloaPirm6u3bFXXODEQP0L\\\", \\\"type\\\": \\\"tool_call\\\"}]\"}", + "{\"tool\": \"{\\n \\\"query\\\": \\\"solid-state EV batteries 2025\\\",\\n \\\"total_results\\\": 5,\\n \\\"results\\\": [\\n {\\n \\\"title\\\": \\\"Solid-state battery technology\\\",\\n \\\"url\\\": \\\"https://www.evinfrastructurenews.com/ev-battery/solid-state-battery-technology\\\",\\n \\\"content\\\": \\\"March 10, 2026 - One of Toyota\\u2019s latest patents (20260024805) from 2025 centres on ensuring that solid-state batteries can be manufactured in the factory while controlling lamination and pressing methods to prevent moisture and contamination in the battery.\\\"\\n },\\n {\\n \\\"title\\\": \\\"All Current And Upcoming EVs With Solid-State Batteries\\\",\\n \\\"url\\\": \\\"https://insideevs.com/news/771402/every-solid-state-battery-ev/\\\",\\n \\\"content\\\": \\\"January 5, 2026 - Update: The first product of the Volkswagen\\u2013QuantumScape partnership may not be an electric car at all, but a motorcycle.

The DSN is auto-generated into a Secret + (key `database-url`) and injected as `DATABASE_URL`; `config.yaml` references + it as `$DATABASE_URL` in `database.postgres_url`. Schema is bootstrapped + automatically on gateway startup (alembic `create_all` + `stamp head`). + For real HA, disable the bundled instance and point at a managed DB: + ```yaml + postgresql: + enabled: false + external: + host: mydb.example.com # or set databaseUrl / existingSecret + port: 5432 + database: deerflow + username: deerflow + password: changeme + ``` +- **Gateway replicas.** Postgres + the Redis stream bridge together make the + gateway's *persisted* state (checkpointer + run/thread metadata) and *live + stream* path cross-pod-safe. The default is still 1 replica: **do not raise + `gateway.replicas` past 1 yet.** Run control — `create_or_reject` dedup, + `cancel`, and orphan reconciliation — is still worker-local (in-process + `asyncio.Lock` + in-memory `record.task`), tracked by [issue + #3948](https://github.com/bytedance/deer-flow/issues/3948). With >1 replica a + double-submit can create two runs on one thread (checkpoint corruption), a + cancel can land on a non-owner pod (409), and a crashed pod's runs stay + `pending`/`running` forever. Stay on 1 replica until that work lands. +- **Redis stream bridge.** A bundled single-instance redis StatefulSet + (`redis.enabled: true`, `redis:7-alpine`) runs in the namespace and the + gateway connects via the in-cluster Service. Per-run SSE events are stored in + Redis Streams (PR #3191) so a client connected to any gateway pod receives + live events and reconnect resumes from `Last-Event-ID`. The URL is + auto-generated into a Secret (key `redis-url`) and injected as + `DEER_FLOW_STREAM_BRIDGE_REDIS_URL`; `config.yaml` sets `stream_bridge.type: + redis` by default. No-auth by default (ClusterIP isolation, matching compose); + set `redis.auth.password` to enable AUTH. For a managed Redis, disable the + bundled instance and point at it via `redis.external`. +- **Persistence.** A PVC (`-home`) backs `/app/backend/.deer-flow` + (sqlite DB, memory, custom agents, per-thread user-data). The gateway mounts + it with `subPath: deer-flow` so the layout matches the provisioner's PVC + user-data mode. Default `ReadWriteOnce`; use `ReadWriteMany` (NFS) on + multi-node clusters so sandbox Pods on other nodes can mount it. +- **Provisioner RBAC.** The provisioner gets a ServiceAccount with a namespaced + Role (get/list/watch/create/delete on pods + services) and a narrow ClusterRole + (namespace get/create). It uses in-cluster service-account creds — no + kubeconfig mount. The unused update/patch/pods-exec/events verbs were dropped + (audited against `docker/provisioner/app.py`). +- **Skills.** Disabled by default (emptyDir at `/app/skills`). Populate via + `skills.existingClaim` or `skills.configMap`, or bake skills into a custom + gateway image. + +## Security + +### Enforced posture + +All workloads run as **non-root** with **all Linux capabilities dropped**. No +container escalates privileges or runs as uid 0. + +| workload | runAsUser | fsGroup | writable-path handling | +|---|---|---|---| +| gateway | 1000 | 1000 | `.deer-flow` PVC group-writable via fsGroup; `PYTHONDONTWRITEBYTECODE=1` suppresses `.pyc` writes; `UV_CACHE_DIR=/tmp` | +| frontend | 1000 (`node`) | 1000 | `emptyDir` at `/app/frontend/.next/cache` (root-owned in the image) | +| nginx | 101 (`nginx`) | 101 | command writes the rendered config to `/tmp/nginx.conf` and loads `nginx -c /tmp/nginx.conf` (since `/etc/nginx` is root-owned); `emptyDir` at `/var/cache/nginx` | +| provisioner | 1000 | — | no PVC; `PYTHONDONTWRITEBYTECODE=1` | +| postgres | 999 (`postgres`) | 999 | official `postgres:16` entrypoint detects non-root and skips the chown/gosu dance; data PVC group-writable via fsGroup | +| redis | 999 (`redis`) | 999 | official `redis:7-alpine` entrypoint detects non-root and skips the gosu dance; data PVC group-writable via fsGroup | + +Every container sets: + +- `runAsNonRoot: true` +- `allowPrivilegeEscalation: false` +- `capabilities.drop: ["ALL"]` +- `seccompProfile: { type: RuntimeDefault }` + +All listening ports are >1024 (8001 / 3000 / 2026 / 8002 / 5432), so no +`NET_BIND_SERVICE` capability is required. + +**ConfigMap rollout.** ConfigMaps mount via `subPath`, which does **not** receive +in-place updates — a `helm upgrade` that changes only a ConfigMap would leave +pods on stale config. Each pod template carries a `checksum/*` annotation (SHA256 +of the rendered ConfigMap): `checksum/config` + `checksum/extensions` on the +gateway, `checksum/nginx` on nginx. Any content change alters the pod spec and +triggers a rolling restart. + +**Resource defaults.** Every workload ships with modest requests+limits in +`values.yaml`; override per workload (`gateway.resources`, `frontend.resources`, +`nginx.resources`, `provisioner.resources`, `postgresql.primary.resources`, +`redis.primary.resources`). + +### Not yet enforced (deferred hardening) + +These are intentionally **not** set in this chart revision. Each can be added +per-workload with testing: + +- **`readOnlyRootFilesystem: true`** — makes the container's root filesystem + immutable so a compromised process can't persist changes to the image. Not + enabled because it requires auditing every runtime write path and mounting an + `emptyDir` over each. Known paths: + - gateway / frontend / nginx / provisioner: `/tmp` (uv cache, python tempfiles, + the nginx config + pid, node temp) — one `emptyDir` at `/tmp` each. + - postgres: `/tmp` **and** `/var/run/postgresql` (the Unix-socket dir). + The first four are mechanical. **postgres is the hard case** — the official + image writes its socket to `/var/run/postgresql` and isn't designed for a + read-only root, so it may need socket-path redirection (`PGHOST`/`unix_socket_directories`). + Optionally, add `USER` directives to the `backend/Dockerfile`, + `frontend/Dockerfile`, and `docker/provisioner/Dockerfile` so the images are + non-root by default (defense in depth — the chart already forces the uid via + `securityContext`, so this is not required). A cluster enforcing the + `restricted` Pod Security Admission standard would require this setting. +- **Provisioner RBAC narrowing.** The Role grants get/list/watch/create/delete + on pods and services in the namespace (update/patch/pods-exec/events were + dropped as unused). These verbs still apply to *all* Pods in the namespace, + not just sandbox Pods — RBAC can't scope by label, so the remaining + options are a dedicated sandbox namespace or admission control (OPA/Kyverno). +- **`startupProbe`.** Workloads have readiness + liveness probes but no startup + probe. The gateway's `livenessProbe.initialDelaySeconds: 30` covers slow starts + today; a `startupProbe` would let it take arbitrarily long to initialize + without risking a liveness kill during a cold start (e.g. slow model config + load). + +None of these affect correctness of the current deployment. + +### Migrating an existing volume to non-root + +`fsGroup` does **not** apply to `subPath` mounts, and it changes group ownership +but not file mode — so a PVC written by an earlier **root** run (e.g. a cluster +that ran the gateway as root before enabling this hardening, or a backup restore +of root-owned files) will keep files like `.jwt_secret` at `0600 root:root`. The +non-root gateway (uid 1000) then can't read them and crashes on the first auth +request with `RuntimeError: Failed to read JWT secret from .../​.jwt_secret`. + +**Fresh installs are unaffected** — uid 1000 creates every file as `1000:1000`. + +To fix an existing root-written PVC, run a one-shot root pod that chowns the +volume to the gateway uid (1000), then restart the gateway: + +```bash +cat <<'EOF' | kubectl apply -n deer-flow -f - +apiVersion: v1 +kind: Pod +metadata: { name: fix-home-perms, namespace: deer-flow } +spec: + restartPolicy: Never + containers: + - name: chown + image: busybox:1.36 + command: ["sh", "-c"] + args: ["chown -R 1000:1000 /home-pvc/deer-flow && chmod -R g+rwX /home-pvc/deer-flow"] + volumeMounts: + - { name: home, mountPath: /home-pvc } + volumes: + - name: home + persistentVolumeClaim: { claimName: deer-flow-deer-flow-home } +EOF +kubectl -n deer-flow wait --for=condition=Ready pod/fix-home-perms --timeout=30s +kubectl -n deer-flow delete pod fix-home-perms +kubectl -n deer-flow rollout restart deploy/deer-flow-deer-flow-gateway +``` + +(On a single-node cluster the fix pod can mount the RWO PVC concurrently with the +gateway; on multi-node, scale the gateway to 0 first.) A durable alternative — +an opt-in root `volumePermissions` initContainer that chowns on every start (the +Bitnami pattern) — is not yet wired into this chart; it would introduce a root +container, so it's left as an operator decision for now. + +## Sandbox NodePort reachability + +The provisioner returns `http://{NODE_HOST}:{NodePort}` to the gateway so the +agent can reach its sandbox.

TanStack Query manages server state; localStorage stores user settings +6. Components subscribe to thread state and render updates `/goal` and `/compact` are built-in composer commands, not skill activations. `src/components/workspace/input-box.tsx` intercepts `/goal`, `/goal clear`, and `/goal ` before normal chat submission, calling Gateway `GET/PUT/DELETE /api/threads/{thread_id}/goal`. Setting `/goal ` 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. Human input requests are a structured message protocol layered on normal chat history. The backend writes request payloads to `ToolMessage.artifact.human_input`, `src/core/messages/human-input.ts` owns the runtime validators/types, and `src/components/workspace/messages/human-input-card.tsx` renders the reusable card. `MessageList` owns answered/latest/pending state for visible cards, but derives answered responses from raw `thread.messages` because replies are hidden; pending cards clear when the hidden reply appears, when dispatch is dropped, or when a new `thread.error` reports an async stream failure. Page-level submit callbacks must send a normal human message and put `hide_from_ui: true` plus the response payload in the fourth `sendMessage(..., options)` argument as `options.additionalKwargs`; the third argument remains run context such as `{ agent_name }`. Composer entry points should disable normal bottom input while `hasOpenHumanInputRequest(...)` is true so users answer through the card and preserve response metadata. +Tool-calling AI messages can contain user-visible text as well as `tool_calls`. `core/messages/utils.ts` keeps these turns in an `assistant:processing` group, and `components/workspace/messages/message-group.tsx` must render the visible text as a processing step instead of treating the message as only tool metadata. This preserves provider text such as error explanations or "trying another approach" notes during tool-heavy runs. + ### Key Patterns - **Server Components by default**, `"use client"` only for interactive components - **Thread hooks** (`useThreadStream`, `useSubmitThread`, `useThreads`) are the primary API interface - **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** (`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. `core/tasks/steps.ts` is the pure 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/subtask-update.ts::computeNextSubtask` is the pure per-subtask state transition (merge step deltas, keep terminal status stable); `core/tasks/context.tsx`'s `useUpdateSubtask` applies it 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. +- **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.
