Surface artifacts produced via the present_files tool in the CLI debug
REPL so headless clients without a frontend (VS Code launch configs,
etc.) can locate output files. Each turn prints newly added artifacts
plus their resolved host path. Works for any source that goes through
present_files — ACP agents, subagents, or sandbox writes.

* feat(middleware): inject dynamic context via DynamicContextMiddleware
Move memory and current date out of the system prompt and into a
dedicated <system-reminder> HumanMessage injected once per session
(frozen-snapshot pattern) via a new DynamicContextMiddleware.
This keeps the system prompt byte-exact across all users and sessions,
enabling maximum Anthropic/Bedrock prefix-cache reuse.
Key design decisions:
- ID-swap technique: reminder takes the first HumanMessage's ID
(replacing it in-place via add_messages), original content gets a
derived `{id}__user` ID (appended after). Preserves correct ordering.
- hide_from_ui: True on reminder messages so frontend filters them out.
- Midnight crossing: date-update reminder injected before the current
turn's HumanMessage when the conversation spans midnight.
- INFO-level logging for production diagnostics.
Also adds prompt-caching breakpoint budget enforcement tests and
updates ClaudeChatModel docs to reference the new pattern.

* fix: fix nginx
* fix(middleware): always inject date; gate memory on injection_enabled
Date injection is now unconditional — it is part of the static system
prompt replacement and should always be present. Memory injection
remains gated by `memory.injection_enabled` in the app config.
Previously the entire DynamicContextMiddleware was skipped when
injection_enabled was False, which also suppressed the date.

ambiguous 'None__user' derived IDs and message collisions
- Downgrade per-turn no-op log to DEBUG; keep actual injection events at INFO
- Add two new tests: missing-id UUID fallback and user-text false-positive

* fix(task): remove max_turns parameter from task tool interface
Subagents should always use their configured max_turns value. Exposing
this parameter allowed callers to override the admin-configured limit,
which is undesirable. The value is now exclusively driven by subagent
config (per-agent overrides and global defaults in config.yaml).

* fix(tools): introduce Runtime type alias to eliminate Pydantic serialization warning
Add deerflow/tools/types.py with:
Runtime = ToolRuntime[dict[str, Any], ThreadState]
Replace every runtime: ToolRuntime[ContextT, ThreadState] and
runtime: ToolRuntime[dict[str, Any], ThreadState] annotation in
sandbox/tools.py, present_file_tool.py, task_tool.py, view_image_tool.py,
and skill_manage_tool.py with the new Runtime alias.
The unbound ContextT TypeVar (default None) caused
PydanticSerializationUnexpectedValue warnings on every tool call because
LangChain's BaseTool._parse_input calls model_dump() on the auto-generated
args_schema while DeerFlow passes a dict as runtime context.
Binding the context to dict[str, Any] aligns Pydantic's serialization
expectations with reality and removes the noise from all run modes.

Remove the "context" substring condition from the Pydantic warning
filter — asserting that no PydanticSerializationUnexpectedValue fires
at all is both simpler and more comprehensive, since the test payload
contains only the tool's own args plus runtime.
Also update the module docstring to remove the version-specific warning
format example that was inconsistent with the looser filter.

* fix(chat): prevent first user message from being swallowed in new conversations
The optimistic message clearing effect cleared too eagerly — any stream
message (including AI messages from messages-tuple events) triggered the
clear before the server's human message had arrived via values events.
For new threads this caused the user's first prompt to disappear permanently.
Only clear optimistic messages once the server's human message has been
confirmed to arrive in thread.messages, not just when any message arrives.

* refactor(loop-detection): collapse dual validation to LoopDetectionConfig
Modifications
- LoopDetectionMiddleware.__init__: stripped of all ValueError raises;
becomes a plain field-assignment constructor.
- LoopDetectionMiddleware.from_config: classmethod that builds the
middleware from a Pydantic-validated LoopDetectionConfig and handles
the ToolFreqOverride -> tuple[int, int] conversion.
- agents/factory.py: SDK construction routed through
LoopDetectionMiddleware.from_config(LoopDetectionConfig()) so the
defaults path is Pydantic-validated too.
- agents/lead_agent/agent.py: uses from_config instead of unpacking
config fields by hand.
- tests/test_loop_detection_middleware.py: deleted TestInitValidation
(16 methods exercising the removed __init__ checks); added
TestFromConfig (4 tests: scalar field mapping, override tuple
conversion, empty overrides, behavioral smoke test).
Result: one validation layer (Pydantic), zero duplication, no __new__
hacks. Both production construction sites flow through LoopDetectionConfig.
Test results
make test -> 2977 passed, 18 skipped, 0 failed (137s)
make format -> All checks passed; 411 files left unchanged
* feat(agents): make loop_detection configurable in create_deerflow_agent
Adds a `loop_detection: bool | AgentMiddleware = True` field to
RuntimeFeatures, mirroring the existing pattern used by `sandbox`,
`memory`, and `vision`. SDK users can now disable LoopDetectionMiddleware
or replace it with a custom instance built from their own
LoopDetectionConfig — e.g.
`LoopDetectionMiddleware.from_config(my_cfg)` — instead of being stuck
with the hardcoded defaults previously installed by the SDK factory.
The lead-agent path (which already reads AppConfig.loop_detection) is
unchanged, and the default `True` preserves prior always-on behavior for
all existing callers.

* fix(frontend): defer thread id to onStart to avoid 404 on new chat
The LangGraph SDK's useStream eagerly fetches /threads/{id}/history the
moment it receives a thread id, and the local useThreadRuns issues
GET /threads/{id}/runs for the same reason. The chats page used to flip
isNewThread=false (and forward the client-generated thread id) inside
the synchronous onSend callback, before thread.submit had created the
thread on the backend. The two queries therefore raced ahead of
POST /runs/stream and returned 404 on the very first send.
Drop the onSend handler so isNewThread stays true until onStart fires
from useStream's onCreated — by then the backend has the thread, and
the SDK's submittingRef guard naturally suppresses the redundant
history fetch. The agent chat page already uses this pattern, so this
also unifies the two flows.
Adds an E2E regression that records request ordering and asserts
GET /history and GET /runs are never issued before POST /runs/stream
on the first send from /chats/new.
Closes#2746
* fix(frontend): split welcome layout from backend thread state
Removing onSend kept GET /history and GET /runs from racing ahead of
POST /runs/stream, but it also coupled the welcome layout (centered
input, hero, quick actions) to backend thread creation. Until onCreated
returned, the user's optimistic message and the welcome hero rendered on
top of each other.
Introduce a dedicated `isWelcomeMode` UI flag, separate from
`isNewThread`:
- `isNewThread` still tracks "backend has no thread yet" and gates the
thread id forwarded to useStream.
- `isWelcomeMode` drives the visual layout (header background, input
box position, max width, hero, quick actions, autoFocus) and flips to
false inside onSend so the layout animates immediately.
`isWelcomeMode` is kept in sync with `isNewThread` via an effect so
sidebar navigation and "new chat" still behave correctly. All 15 E2E
tests pass, including the ordering regression added in the previous
commit.
* test(e2e): use monotonic sequence for thread-init ordering check
Date.now() is millisecond-resolution, so two requests emitted within
the same tick would share a timestamp and slip past the strict `<`
ordering assertions. Replace the timestamp with a monotonic counter
that increments on every observed request/requestfinished event so the
ordering check is robust regardless of scheduling.
Per PR #2749 review feedback from copilot-pull-request-reviewer.
* refactor(input-box): rename isNewThread prop to isWelcomeMode
Inside InputBox, the prop named `isNewThread` is only ever consulted
for visual layout decisions — gating follow-up suggestions, the bottom
background strip, and the welcome-mode quick-action SuggestionList. It
never reflects "the backend has created the thread", which after #2746
is tracked separately via `isNewThread` in the chat pages themselves.
Rename the prop to `isWelcomeMode` and update both call sites
(workspace chats page and agent chats page) so the prop name matches
its actual semantics. No behavior change.
Per PR #2749 review feedback from @WillemJiang.
* feat(agent): add update_agent tool for in-chat custom-agent self-updates (#2616)
Custom agents had no built-in way to persist updates to their own SOUL.md /
config.yaml from a normal chat — `setup_agent` was only bound during the
bootstrap flow, so when the user asked the agent to refine its description
or personality, the agent would shell out via bash/write_file and the edits
landed in a temporary sandbox/tool workspace instead of
`{base_dir}/agents/{agent_name}/`.
Changes:
- New `update_agent` builtin tool with partial-update semantics (only the
fields you pass are written) and atomic temp-file + os.replace writes so
a failed update never corrupts existing SOUL.md / config.yaml.
- Lead agent now binds `update_agent` in the non-bootstrap path whenever
`agent_name` is set in the runtime context. Default agent (no
agent_name) and bootstrap flow are unchanged.
- New `<self_update>` system-prompt section is injected for custom agents,
instructing them to use `update_agent` — and explicitly NOT bash /
write_file — to persist self-updates.
- Tests: 11 new cases in `tests/test_update_agent_tool.py` covering
validation (missing/invalid agent_name, unknown agent, no fields),
partial updates (soul-only, description-only, skills=[] vs omitted),
no-op detection, atomic-write safety, and AgentConfig round-tripping;
plus 2 new cases in `tests/test_lead_agent_prompt.py` covering the
self-update prompt section.
- Docs: updated backend/CLAUDE.md builtin tools list and tools.mdx
(en/zh) with the new tool description.

* fix(loop-detection): avoid IMMessage leak to downstream consumer
* fix(channels): filter loop warning text from IM replies
* fix(frontend): unify gateway-config localhost fallback for prod (#2705)
`getGatewayConfig()` only fell back to localhost defaults when
`NODE_ENV === "development"`, while `next.config.js` always falls back
to `127.0.0.1:8001`. Running `make start` (which sets NODE_ENV=production
via `next start`) without `DEER_FLOW_INTERNAL_GATEWAY_BASE_URL` /
`DEER_FLOW_TRUSTED_ORIGINS` therefore caused zod to throw inside SSR
layouts and surfaced as a 500.
Drop the NODE_ENV gating and use localhost defaults everywhere — the
"force explicit config in prod" intent should be enforced by deployment
templates (docker-compose already sets both vars), not by request-time
crashes. Document the two vars in both .env.example files and add unit
coverage for the dev/prod env-unset paths.

* fix(gateway): return ISO 8601 timestamps from threads endpoints (#2594)
ThreadResponse documents created_at / updated_at as ISO timestamps,
matching the LangGraph Platform schema (langgraph_sdk.schema.Thread
exposes them as datetime, JSON-encoded as ISO 8601). The gateway
threads router was instead emitting str(time.time()) — unix-second
floats — breaking frontend new Date() parsing and producing a mixed
ISO/unix wire format that also corrupted the search sort order.
Centralize timestamp generation in deerflow.utils.time:
- now_iso() — datetime.now(UTC).isoformat()
- coerce_iso(x) — heals legacy unix-timestamp strings on read so the
store converges to ISO without a one-shot migration
threads.py: replace 6 time.time() call sites with now_iso(); wrap all
read paths and Phase-2 checkpoint metadata with coerce_iso(); _store_upsert
opportunistically heals legacy created_at on update; drop unused time import.
thread_runs.py: reuse now_iso() instead of a private duplicate _now_iso(),
preventing future drift between the two timestamp call sites.
Tests: 9 unit tests for the helper; 5 integration tests pinning the ISO
contract for create/get/patch/search and the legacy-healing path on the
internal store upsert. Full suite: 2144 passed, 15 skipped, 0 failed.
Closes#2594
* fix(gateway): coerce checkpoint metadata timestamps to ISO on read
After the merge with main, three additional read paths in ``threads.py``
were still emitting raw ``str(metadata.get("created_at", ""))`` —
``get_thread_state``, ``update_thread_state``, and ``get_thread_history``.
Same root cause as #2594: when the checkpoint metadata's ``created_at``
is a unix-second float (legacy data, or a checkpoint written by an older
Gateway version), ``str(float)`` produces ``"1777252410.411327"`` and the
frontend's ``new Date(...)`` returns ``Invalid Date``. The fix on the
``/threads/{id}`` GET path was already in place; these three sibling
endpoints needed the same treatment.
All four call sites now flow through ``coerce_iso``, so:
- legacy float metadata heals to ISO on the way out,
- ISO metadata passes through unchanged,
- ``datetime`` instances (which the new ``coerce_iso`` branch handles
explicitly) emit with the ``T`` separator instead of falling through
to the space-separated ``str(datetime)`` form.
Coverage added for the two endpoints not already pinned by the merge:
- ``test_get_thread_state_returns_iso_for_legacy_checkpoint_metadata``
- ``test_get_thread_history_returns_iso_for_legacy_checkpoint_metadata``
Both pre-seed a checkpoint whose metadata carries the literal float
from the issue body and assert the wire format is ISO.
* refactor: thread app config through lead prompt
* fix: honor explicit app config across runtime paths
* style: format subagent executor tests
* fix: thread resolved app config and guard subagents-only fallback
Address two PR review findings:
1. _create_summarization_middleware passed the original (possibly None)
app_config into create_chat_model, forcing the model factory back to
ambient get_app_config() and risking config drift between the
middleware's resolved view and the model's view. Pass the resolved
AppConfig instance through end-to-end.
2. get_available_subagent_names accepted Any-typed config and forwarded
it to is_host_bash_allowed, which reads ``.sandbox``. A
SubagentsAppConfig (also accepted upstream as a sum-type input) has
no ``.sandbox`` attribute and would be silently treated as "no
sandbox configured", incorrectly disabling the bash subagent. Guard
on hasattr and fall back to ambient lookup otherwise.
Adds regression tests for both paths.
* chore: simplify hasattr guard and tighten regression tests
- Collapse if/else into ternary in get_available_subagent_names; hasattr(None, ...) is False so the explicit None check was redundant.
- Drop comments that narrate the change rather than explain non-obvious WHY (test names already convey intent).
- Replace stringly-typed sentinel "no-arg" in regression test with direct args tuple comparison.

* fix(sandbox): pass no_change_timeout to exec_command to prevent 120s premature termination
The agent_sandbox library's shell API defaults no_change_timeout to 120
seconds. When AioSandbox.execute_command() called exec_command() without
this parameter, commands producing no output for 120s would return with

* fix(subagents): fully defer config.yaml load in executor __init__
The previous attempt only relocated the explicit get_app_config() call,
but left resolve_subagent_model_name(...) running eagerly in __init__.
That helper has its own internal get_app_config() fallback, which still
fired when both app_config and parent_model were None and
config.model == "inherit" — exactly the path unit tests hit, breaking
21 tests in CI with FileNotFoundError: config.yaml.
Skip the eager resolve in __init__ when it would require loading the
config file, and defer to _create_agent (which already has the
app_config or get_app_config() fallback).

* fix(agents): propagate agent_name into ToolRuntime.context for setup_agent (#2677)
When creating a custom agent via the web UI, SOUL.md was always written
to the global base_dir/SOUL.md instead of agents/<name>/SOUL.md.
Root cause: the bootstrap flow sends agent_name via body.context, but
two layers were broken:
1. services.py only forwarded body.context keys into config["configurable"];
config["context"] was never populated.
2. worker.py constructed the parent Runtime with a hard-coded
{thread_id, run_id} context, ignoring config["context"] entirely.
After the langgraph >= 1.1.9 bump (#98a5b34f), ToolRuntime.context no
longer falls back to configurable, so setup_agent's
runtime.context.get("agent_name") returned None and the tool's silent
agent_name=None -> base_dir fallback kicked in, overwriting the global
SOUL.md.
Fix:
- services.py: extract merge_run_context_overrides() and write the
whitelisted context keys into both configurable (legacy readers) and
context (langgraph 1.1+ ToolRuntime consumers).
- worker.py: extract _build_runtime_context() and merge config["context"]
into the Runtime's context (without letting callers override
thread_id/run_id).
The base_dir fallback in setup_agent_tool.py is left in place because
the IM /bootstrap channel command depends on it. That code path can
be tightened in a follow-up.
Adds regression tests covering both helpers.

Centralize log level parsing in `logging_level_from_config()` and
application in `apply_logging_level()` within `deerflow.config.app_config`.
- Gateway lifespan applies configured log level on startup
- `debug.py` uses shared helpers instead of local duplicates
- `apply_logging_level()` targets only `deerflow`/`app` logger hierarchies
so third-party library verbosity is not affected; root handler levels
are only lowered (never raised) to allow configured loggers through
without suppressing third-party output; root logger level is not modified
- Config field description updated to clarify scope
- Tests save/restore global logging state to avoid test pollution
