The reasoning-effort selector trigger only appended a value for the four
explicit efforts; when reasoning_effort was unset it rendered
"Reasoning Effort:" with an empty value. The dropdown already treats an
unset effort as medium (highlighted and checked), so the trigger and the
menu disagreed on the default. Show "Medium" in the trigger when unset to
match the dropdown's existing default.
* feat(agents): per-agent model and generation settings
Let each custom agent choose its own model and sampling settings
(temperature, max_tokens) plus thinking / reasoning_effort defaults,
so agents sharing a model profile are no longer stuck with one shared
temperature and output length (#4336).
AgentConfig gains optional model_settings / thinking_enabled /
reasoning_effort (None = inherit). create_chat_model applies per-caller
model_overrides on top of the profile before the thinking/Codex
transforms; the lead agent resolves each knob with precedence
request > agent config > profile/default. The /api/agents create/update
routes persist the fields and reject an unknown model. The default lead
agent path is unchanged (no agent config -> overrides None). The agent
chat composer also stops force-overriding an agent's configured default
model with models[0].
* fix(agents): tri-state thinking control and default-model capability gating
The model-settings dialog seeded the thinking switch to false, so opening
it to tweak temperature and saving silently disabled thinking (the runtime
default is on) with no way back to inherit. It also hid the thinking /
reasoning controls whenever the agent inherited the global default model,
since `__default__` never resolved through `models.find`.
Give thinking an explicit Inherit / On / Off tri-state so an untouched save
is a no-op, and resolve `__default__` to the effective default (models[0])
for the capability check. Logic lives in the tested helpers module.
The composer sent `/goal <objective>` of any length, so an objective past
the backend limit (`MAX_GOAL_OBJECTIVE_CHARS = 4000`) only failed after a
round-trip with a raw HTTP 422. Mirror the limit client-side: reject an
over-length objective before the PUT with a friendly toast, and reject the
submit so PromptInput keeps the user's text for editing instead of clearing
it. Add a live footer counter that surfaces near the limit and turns
destructive when exceeded. Length is measured with the same whitespace
normalization the backend applies, so the counts match exactly.
* feat(browser): add agentic browser control
* fix(frontend): format browser view changes
* fix(browser): keep browser optional and isolate sidecar layout
* fix(browser): address PR review security and IME findings
- Nginx: add a browser-stream WebSocket location before the generic
/api/threads regex so Live upgrades instead of downgrading to HTTP
(both nginx.conf and nginx.local.conf).
- Ownership: require an existing owned thread for the WS stream and REST
navigate, and tear down the browser session on thread deletion so a
later caller cannot reuse a retained page/cookies by guessing the id.
- SSRF: enforce the URL policy at the browser request boundary via a
context-level route guard covering redirects, popups, iframes, and
subresources (skipped for CDP-attached Chrome).
- IME: skip key forwarding while a composition is active so confirming a
CJK candidate with Enter no longer submits the remote page form.
Adds regression tests for the request guard, session teardown on delete,
and the composing-Enter key decision.
* fix(frontend): smooth streaming in long tool threads
* Revert "fix(frontend): smooth streaming in long tool threads"
This reverts commit f0462516eabe77f138d4027ea1c714fb226683cf.
* fix(browser): address review security and lifecycle findings
- Reject cross-origin WebSocket upgrades on the live browser stream
(Origin allow-list reuse of CORS/same-origin helpers) to close a
WS-CSRF hole, and fail closed when the ownership store is absent.
- Warn when a CDP-attached session runs with the SSRF request guard
off, and drop the unreachable CDP screencast teardown dead code.
- Read browser session launch config from a single canonical source
(browser_navigate) so it is deterministic regardless of call order.
- Bound per-thread Chromium accumulation with idle-timeout eviction
and an LRU max-sessions cap.
- Reset the Live reconnect counter on a successful open so the stream
can't permanently stall after the cumulative attempt cap.
* fix(frontend): reduce long tool thread render stalls
Reuse stable historical message groups during streaming, defer heavy Markdown and browser previews, and lazy-decode message images.
* fix(browser): keep live control responsive during continuous input
Why: Manual browser control felt laggy — a physical click ran the remote
Playwright click three times and each non-move input synchronously awaited a
JPEG screenshot, so events queued behind capture (queue wait up to ~237ms).
The first async attempt used a trailing-edge debounce, which froze the visible
page until a wheel/keyboard gesture stopped ("scroll finishes, then it jumps").
What:
- Frontend forwards one `click` per physical click instead of also emitting
`down`/`up`, so the remote page is not clicked twice per gesture.
- Backend detaches live-frame capture from input dispatch: non-move actions
start a rate-limited background refresh loop (leading frame + bounded cadence)
that keeps emitting frames while input continues and never blocks dispatch.
- Add regression tests: input dispatch no longer awaits the screenshot, rapid
inputs coalesce, and continuous input keeps refreshing before it stops.
Scenarios: Verified in the live Browser panel — a single click completes in
~57ms (was blocked behind a 171ms capture), and a 1.14s sustained wheel gesture
renders ~7 frames throughout the scroll instead of one frame after it ends.

* fix(frontend): harden artifact and markdown rendering
* fix(#4117): restore allow-scripts for scroll-restore, fix citation XSS bypass
willem-bd identified these issues:
1. [REGRESSION] sandbox removed allow-scripts which broke HTML artifact
scroll-restoration — the injected postMessage script could not run.
The prior config (allow-scripts allow-forms without allow-same-origin,
i.e. opaque origin) was already safe. Restored with corrected comment.
2. [XSS bypass] CitationLink rendered <a href={href}> directly before
isSafeHref ran, so prompt-injected [citation:x](javascript:...)
bypassed the safety check. Moved citation block after the guard.
Also:
- Added mailto: and tel: to SAFE_HREF_PROTOCOLS
- Kept anchor-only attributes off the <span> fallback (React DOM warning)
Note: the loadMessages re-throw originally in this commit was dropped
during the rebase — upstream #4065 rewrote useThreadHistory as a
TanStack useInfiniteQuery that already surfaces fetch failures.
* test(e2e): update sandbox assertion to match allow-scripts allow-forms
The artifact preview iframe's sandbox was restored to 'allow-scripts allow-forms'
for scroll-restoration. Update the E2E test to expect the corrected value.
* fix(#4117): address review — ArtifactLink XSS guard, urlOfArtifact sandbox e2e
- Apply the isSafeHref guard to ArtifactLink (artifact-link.tsx) so a
prompt-injected javascript:/data: href in a .md artifact preview cannot
reach a real anchor in the main document, matching the guard in
createMarkdownLinkComponent.
- Add an e2e asserting the urlOfArtifact iframe (non-code
browser-previewable files like PDF) keeps its empty sandbox.
Note: the loadMessages error-surfacing changes originally in this commit
were dropped during the rebase — upstream #4065 rewrote useThreadHistory
as a TanStack useInfiniteQuery whose queryFn already throws on
!response.ok and surfaces the failure via a toast.
* fix(frontend): let write_file non-code previewable artifacts render in sandboxed iframe
When a write_file artifact such as PDF is clicked in chat, the component receives a path that forced isCodeFile=true, hiding the sandboxed iframe behind the code editor. Now non-code browser-previewable files are detected early so the sandboxed iframe renders correctly.
Fixes the E2E test: renders sandboxed iframe for a browser-previewable non-code file.
* fix(#4117): align PDF artifact route pattern with convention (drop /mock/ prefix)
The test used /mock/api/threads/... for the PDF artifact content route,
but the urlOfArtifact helper generates /api/threads/... (without /mock/)
when isMock=false. The other tests (e.g. presented artifacts) already use
the correct /api/threads/... pattern.
* test(frontend): add render-level coverage for unsafe markdown/artifact links
- Render MarkdownLink and ArtifactLink via renderToStaticMarkup and
assert an unsafe javascript: href produces a disabled <span> (never an
<a>), including through the citation-labelled branch, and that safe
https hrefs render hardened anchors (target=_blank, rel=noopener).
- The new ArtifactLink render test caught the unsafe href leaking onto
the fallback <span> through the {...rest} spread; drop the spread in
both span fallbacks so anchor-only attributes (href/target/rel) and
react-markdown's node prop never reach the span.
- Cover mailto:/tel: in the isSafeHref unit cases and fix the stale
SAFE_HREF_PROTOCOLS docstring that still claimed http/https-only.
* fix(frontend): route the agent save-hint through the safe localStorage facade
Export safeLocalStorage from core/settings/local and use it for the
agent-create save-hint read/write so blocked browser storage (Safari
private mode, strict containers, embedded WebViews) cannot throw from
the effect. core/agents/feature-cache.ts already guards its
localStorage access with try/catch, so settings + agent pages are now
consistently best-effort.
* fix(frontend): allow scheme-less relative markdown links in isSafeHref
* fix(workspace-changes): classify a symlink replacing a file distinctly from deleted
scan_workspace_roots() skipped every symlinked path entirely
(host_file.is_symlink() -> continue), so the path was completely absent
from a snapshot instead of being recorded as a metadata-only stub the
way binary/large/sensitive-looking files already are. When an agent run
replaces a tracked file with a symlink (e.g. rm config.txt && ln -s
/some/other/path config.txt), the after-snapshot never contained that
path at all, so compare_snapshots()'s _status() saw after_file=None and
reported plain "deleted" -- silently hiding that the path is still alive
on disk, now as a symlink that can point anywhere on the host, including
outside the workspace root.
Add a "symlink" classification mirroring the existing binary/large/
sensitive pattern: scan_workspace_roots() now records a symlink as a
metadata-only FileSnapshot stub (symlink=True, symlink_target from
os.readlink(), lstat'd without ever following the link) instead of
omitting it. _status() reports "symlink_created" whenever a symlink
newly occupies a path that was not already a symlink (brand new or
replacing a prior file), so the security-relevant fact surfaces
distinctly instead of collapsing into "deleted". A symlink genuinely
removed with nothing replacing it is unchanged: still "deleted".
Verified against a real POSIX symlink (WSL; native Windows symlink
creation needs elevated privilege) driving the unmodified
scan_workspace_roots()/compare_snapshots() functions, and via a
patch-file revert/reapply cycle on this same fix to confirm the added
regression tests fail before and pass after.
* fix(workspace-changes): count symlink_created in the changed-file badge
getChangedFileCount summed only created + modified + deleted, so a run
whose only change was a symlink replacing a file (reported as the new
symlink_created status, not deleted) produced a count of 0 and
WorkspaceChangeBadge hid the badge entirely -- the exact scenario this
PR targets, with the opposite of the intended result.
Add symlink_created to the frontend WorkspaceChangeSummary interface
(already emitted by the backend) and include it in the count. The
per-file StatusIcon/statusLabel "modified" fallthrough is unaffected
and left as a follow-up, per review.
Regression test reverts cleanly to reproduce a count of 0 pre-fix.
* fix(workspace-changes): rank symlink_created in file sort and complete the type contract
sortWorkspaceChanges's statusRank had no entry for the new
symlink_created status, so statusRank[left.status] - statusRank[right.status]
evaluated to NaN for any comparison involving a symlink-created file,
violating Array#sort's ordering contract instead of producing a
deterministic order. The frontend WorkspaceChangeStatus and
DiffUnavailableReason unions, and the WorkspaceFileChange symlink
fields, also stayed narrower than what the backend now emits, so
TypeScript's satisfies Record<...> guard on statusRank could not catch
the gap.
Widen WorkspaceChangeStatus to include "symlink_created" and
DiffUnavailableReason to include "symlink", add the matching
symlink/symlink_target_before/symlink_target_after fields to
WorkspaceFileChange, and give symlink_created a rank alongside
modified in statusRank -- restoring the satisfies guard's ability to
catch a future unranked status. unavailableLabel now has an explicit
"symlink" branch (new symlinkUnavailable i18n string, en-US + zh-CN)
instead of falling through to the generic label.
Also fixes the failing e2e-tests CI check: the existing
workspace-changes.spec.ts mock summary predates the symlink_created
field, so getChangedFileCount computed 1 + 1 + 0 + undefined = NaN and
the badge rendered "Edited NaN files" instead of "Edited 2 files".
Added symlink_created: 0 to the mock to match the real backend
contract.
New sortWorkspaceChanges unit tests revert cleanly against the
unranked statusRank to reproduce the NaN-driven misordering. pnpm test
(626 tests), pnpm check, and pnpm format are clean, and the
previously-failing e2e spec plus the full e2e suite (94 tests) pass.
* fix(auth): let deployments close local self-registration
The OIDC provisioning policy (allowed_email_domains, require_verified_email,
auto_create_users) is enforced only in the SSO callback via
get_or_provision_oidc_user. POST /api/v1/auth/register creates a local account
without consulting any of it, and nothing can turn that path off, so a
deployment declaring an email-domain allowlist can still be joined by any
address through local registration.
Add auth.local.allow_registration (default true, so existing deployments are
unchanged) and gate /register on it before the account is created. Report the
flag from /setup-status so the login page stops offering a signup entry the
Gateway will reject.
/initialize is deliberately not gated: it is the bootstrap path, guarded by
admin_count == 0, and closing it would leave a fresh install unable to create
its first admin.
An unreadable config.yaml falls back to the pre-gate default (open) rather than
making these two endpoints a hard dependency on the file.
* docs(auth): align registration-gate fallback wording with the FileNotFoundError catch
* fix(frontend): use code-aware stripLeakedSystemTags for all internal marker tags
Replace the ad-hoc /<\/?memory>/g in ClipboardSafeStreamdown with a
dedicated stripLeakedSystemTags() function in preprocess.ts that:
- Covers all INTERNAL_MARKER_TAGS (<memory>, <system-reminder>,
<current_date>, <uploaded_files>, <slash_skill_activation>) instead
of only <memory>
- Is code-aware: skips fenced code blocks (```) and indented code
blocks (4-space indent), so user-written meta-discussions about the
memory system are not silently stripped
- Handles opening tags, closing tags, self-closing tags, and tags with
attributes
- Adds 15 unit tests covering all the above cases
* fix(frontend): use marker-aware fence tracking in stripLeakedSystemTags
The boolean insideFence toggle incorrectly closes a fence on any line
matching 3+ backticks or tildes, regardless of the actual delimiter.
This causes tags inside a tilde-fenced block containing a backtick
sub-fence, or a 4-backtick block containing a 3-backtick sub-fence, to
be silently stripped.
Track the opening fence marker (character and run length) so that only
a matching marker with at least the same length closes the fence.
Adds 4 new test cases:
- Tilde fence with inner backtick fence
- 4-backtick fence with inner 3-backtick fence
- Shorter tilde closing inside longer tilde fence
- Tags stripped after real closing fence
* fix(frontend): fix TypeScript strict errors in fence marker tracking
- Use non-null assertion (!) on fenceMatch[1] (guaranteed by regex)
- Use charAt(0) instead of [0] to avoid string | undefined type
* feat(memory): pluggable + self-contained memory system (MemoryManager plan phases 1 & 2)
Phase 1 — Pluggable (steps 0-10):
- ABC MemoryManager (9 methods) + singleton factory + drop-in backend discovery
- DeerMem default backend with core/ (storage/queue/updater/prompt/message_processing)
- NoopMemoryManager backend (proves pluggability)
- All call sites (middleware/hook/prompt/gateway/client/app) routed through manager
- hasattr capability probing for DeerMem-internal methods (no hard imports)
- MemoryConfig gains manager_class field; shared vs DeerMem-private annotated
Phase 2 — Self-contained DeerMem (steps 11-18):
- backend_config passthrough + DeerMemConfig (all DeerMem-private fields moved off MemoryConfig)
- DI: DeerMem owns storage/queue/updater/llm as instance attributes (no global singletons)
- Storage independence: core/paths.py with own root (~/.deermem or ),
factory auto-injects deer-flow's runtime_home() as absolute base_dir (zero-config)
- LLM independence: core/llm.py via langchain init_chat_model (no create_chat_model)
- Trace independence: optional tracing_callback replaces inject_langfuse_metadata/request_trace_context
- Message processing independence: hide_from_ui default-skip + optional should_keep_hidden_message hook
- Internal imports → relative (only deer_mem.py ABC import is host-relative)
- Carrier (deer_mem.py adapter) / portable (deermem/ config+core) split
- New tests: test_deermem_self_contained + test_memory_manager_pluggable; all memory tests migrated
- Other-agent demo: samples/other_agent_demo/ + automated portability test
- config.example.yaml memory section updated to phase-2 schema
* feat(memory): port consolidation + staleness fix into self-contained DeerMem; phase-2 host hooks
Port upstream #3996 (memory consolidation) and #3993 (staleness KeyError fix)
from origin/MemoryManager into the pluggable, self-contained DeerMem structure
(backends/deermem/deermem/), adapted to the DI MemoryUpdater (config injected,
not get_memory_config globals):
- DeerMemConfig: add consolidation_enabled (opt-in, default false) /
consolidation_min_facts / consolidation_max_groups_per_cycle /
consolidation_max_sources
- prompt.py: factsToConsolidate JSON field + {consolidation_section} placeholder
+ CONSOLIDATION_PROMPT constant
- updater.py: _coerce_source_confidence / _select_consolidation_candidates /
_build_consolidation_section module helpers (matching the existing
_select_stale_candidates style); consolidation normalization in
_normalize_memory_update_data; consolidation apply in _apply_updates (after
max_facts trim, with apply-time guardrails mirroring staleness); staleness
KeyError fix (f["id"] -> f.get("id") is not None) applied to both the
staleness guardrail and the consolidation allowed_source_ids comprehension
- config.example.yaml: consolidation section under memory.backend_config
- tests/test_memory_consolidation.py: 40 DI-adapted tests (running, not skipped)
incl. the staleness KeyError regression
Also includes in-flight phase-2 host-integration work: storage_path semantics
(any absolute/relative value = root dir) and host-default tracing_callback /
should_keep_hidden_message hooks injected into backend_config by the factory.

* feat(memory): add noop backend template and backends guide
- backends/noop/: complete drop-in template (config.py with zero deer-flow
imports, noop_manager.py with a 6-step new-backend walkthrough in its
docstring, commented optional fact-CRUD capabilities).
- backends/README.md: which files to touch when adding/swapping a backend,
the 5-item backend contract, and common pitfalls.
- manager.py: generalize backend examples in comments (drop mem0-specific
references).

* fix(frontend): guard formatTimeAgo against invalid timestamps
Return a neutral placeholder when the input date is invalid (e.g. an empty lastUpdated from a backend with no memories) instead of throwing 'Invalid time value' from date-fns.
Co-Authored-By: Claude <noreply@anthropic.com>
* feat(memory): wire tool-driven memory mode through the MemoryManager ABC
tools.py (memory_search/add/update/delete) now calls get_memory_manager()
instead of the removed host memory module, so tool mode (memory.mode: tool)
works for any backend. DeerMem.search is implemented (case-insensitive
substring match, ranked by confidence) as a stand-in for the planned
semantic retrieval; noop.search returns [] (unchanged). Fact-CRUD tools
use getattr+callable probing -- backends lacking those ops (noop) get a
clear JSON error instead of crashing.
Tests: test_memory_tools rewired to mock the manager (handler tests) +
TestModeGating retained; test_memory_search now covers DeerMem.search;
pluggable stubs test updated (search no longer a stub).

* fix: resolve lint errors (import sorting, type annotation quotes, E402 in skipped tests)
* docs: restore explanatory comments in config.example.yaml memory section
* fix(security): port html-escape memory facts fix (#4097) to vendored DeerMem prompt.py
* fix(memory): address review + port dropped upstream memory fixes
Review blockers (vendored DeerMem):
- #4044 restore _escape_memory_for_prompt (current_memory blob in
MEMORY_UPDATE_PROMPT) - prevents </current_memory> breakout
- #4028 html.escape staleness-section cat/content in _build_staleness_section
- #4119 add _escape_summary for injection-path summaries (Work/Personal/
Current Focus/Recent/Earlier/Background)
- default-model silent no-op: factory injects host default chat model via a
new host_llm slot (create_chat_model(name=None)); DeerMem prefers host_llm
over build_llm(model). Zero-config extraction works out of the box again
- MemoryConfigResponse: fix stale docstring (backend-agnostic shape; DeerMem
knobs live under backend_config, not top-level - restoring flat would
re-couple the API to DeerMem). Frontend audited: does not read /memory/config
- _host_default_tracing_callback: restore langfuse assistant_id/environment
- search: push category onto the ABC signature; DeerMem filters BEFORE the
top_k slice (was filtered client-side after slicing -> starved results)
- _do_update_memory_sync: split into wrapper+impl; bind trace_id into the
request-trace ContextVar on the Timer/executor worker via a new
trace_context_manager host hook (None trace_id left unbound - no fabrication)
- client.py fact-CRUD now passes user_id (was writing to the global bucket
while get_memory reads per-user)
- _resolve_manager_class: fail-fast (raise ValueError) on an unresolved
explicit manager_class instead of silently falling back to DeerMem (memory is
persistent state - a wrong store is a silent data-integrity footgun)
Upstream memory fixes dropped by the host->vendored rename conflict, re-ported
to backends/deermem/deermem/core/ (+ deer_mem.py):
- #4073 queue busy-timer-spin -> _reprocess_pending flag (core/queue.py)
- #4074 null source.confidence in staleness -> _coerce_source_confidence
(core/updater.py: _build_staleness_section + _apply_updates stale sort)
- #4075 factsToRemove is optional (drop from _REQUIRED_MEMORY_UPDATE_TOP_LEVEL_KEYS)
- #4076 null confidence in search ranking -> _coerce_source_confidence
(deer_mem.py DeerMem.search)
host_llm + trace_context_manager are host-injected via backend_config (factory
in manager.py), keeping backends/deermem/ at exactly one `from deerflow` line
(the ABC contract) - portability test preserved.

* fix: resolve lint errors (F541 f-string without placeholders, E501 line too long)
* fix(memory): restore hide_from_ui clarification preservation, expose mode
Two memory-system fixes (F541/E501 lint was already fixed on this branch):
- filter_messages_for_memory: restore default preservation of well-formed
human_input_response clarification answers (v2 regression). The
self-containment refactor made the bare function skip ALL hide_from_ui when
no hook was passed, but upstream preserves well-formed clarification
responses by default (test_hide_from_ui_human_input_response_is_preserved).
Inline a host-agnostic _is_human_clarification_response mirror of
read_human_input_response as the default keep-decision; the host-injected
should_keep_hidden_message hook still overrides (production path unchanged).
Portable package stays zero `from deerflow`.
- /memory/config: expose `mode` (middleware|tool) in MemoryConfigResponse +
the config/status endpoints + client.get_memory_config. mode is a host-
shared, behavior-determining field missing from the response projection.
Sync tests (mock .mode; e2e assert mode present).
- Align manager_class field docstring with fail-fast behavior.
Tests: filter/self-contained/portability (35) + memory-config (4) pass;
ruff clean.
Co-Authored-By: Claude <noreply@anthropic.com>
* fix(memory): resolve ruff format failures in memory module + tests
`make lint` runs `ruff format --check` in addition to `ruff check`; 8 memory
files had pending format changes -- 7 pre-existing (deer_mem, updater, tools,
test_memory_queue/router/search/tools) + message_processing from the
hide_from_ui fix. Apply `ruff format`: whitespace/wrapping only, no logic
change. 109 memory tests pass; ruff check + format --check both clean.

* fix(memory): address PR review - legacy field migration, fact_id contract, path/docs
Address willem-bd's review on PR head bc8bf0d4 (risk:high, persistent state):
- config: auto-migrate pre-abstraction top-level memory.* DeerMem fields
(storage_path, max_facts, debounce_seconds, model_name, token_counting,
staleness_*, consolidation_*) into backend_config on load + warn, so an
upgrade does NOT silently revert customized settings (was: silent
extra='ignore' drop). model_name -> backend_config.model.model. Unknown
top-level keys warned.
- factory: resolve a relative backend_config.storage_path against runtime_home()
(base_dir-relative, CWD-independent) to preserve pre-abstraction semantics;
paths.py stays portable (no runtime_home import).
- tools: memory_add uses the fact_id returned directly by create_fact instead of
re-deriving it via content-key matching (coupled the tool to the backend's
content normalization; could misreport a storage cap). create_fact now returns
(memory_data, fact_id); gateway/client/tool updated. Fix terse
{"error":"content"} -> {"error":"empty content"}.
- app.py: update stale token_counting=="char" warm-up comment to point at
manager.warm (DeerMem.warm re-checks char and returns early).
- router: comment explaining reload_memory silent fallback vs fact 501 asymmetry
(read-only degrade vs write fail-loud).
- CHANGELOG: document breaking changes (/memory/config + client.get_memory_config
shape flat->backend_config; custom storage_class path moved + __init__ must
accept config) and the legacy-field auto-migration.
- tests: add regression test pinning the per-user memory path
({storage_path}/users/{safe_user_id}/memory.json == host make_safe_user_id)
across the abstraction; update create_fact mocks for (memory_data, fact_id).
Tests: 273 passed (memory suite); ruff check + format clean.

* fix(memory): address PR review - storage_path, max_facts, tracing, parsing
Six review findings (willem-bd), each verified against upstream:
- storage_path semantics (file -> root dir): migration drops file-style
(.json) legacy values with a warning; factory raises if storage_path
resolves to an existing file (avoid silent NotADirectoryError write
failure). CHANGELOG + config.example.yaml comment updated.
- create_memory_fact enforces max_facts again (via _trim_facts_to_max) and
returns (memory, None) when the cap evicts the new fact; memory_add tool
reports "not stored", client raises ValueError, POST /memory/facts -> 409.
- max_facts trim uses _coerce_source_confidence (was raw f.get("confidence",
0) -> TypeError on non-float imported/legacy confidence, swallowed as
silent update failure).
- memory-tracing assistant_id restored to "memory_agent" (was "lead-agent"
copy-paste; matches upstream + DeerMem run_name).
- _is_human_clarification_response cross-checked against
read_human_input_response (drift guard test).
- empty-string legacy values skipped silently in migration (narrow fix, not
broad "if not value" which would skip explicit bool False).
8 new regression tests. make lint + 406 memory tests pass.
Co-Authored-By: Claude <noreply@anthropic.com>
* fix(memory): address internal review - storage fail-fast, build_llm degrade, config warn, noop template
Addresses 4 findings from the PR #4122 internal supplemental review
(parallel to willem-bd's review, no overlap):
- create_storage fail-fast: a misspelled/unimportable storage_class now
raises ValueError instead of silently falling back to FileMemoryStorage.
Memory is persistent state, so a wrong store is a data-integrity footgun;
mirrors the existing manager_class resolution policy. (storage.py)
- noop template create_fact signature: the commented template used
keyword-only `content` and returned a bare dict, while DeerMem's actual
create_fact takes positional `content` and returns tuple[dict, str|None]
(the memory_add tool passes content positionally; gateway/client/tools all
tuple-unpack). A backend copied from the template would 500 on fact-CRUD.
Template fixed; delete_fact/update_fact templates left (callers compatible).
(noop_manager.py)
- build_llm graceful degrade: wrap init_chat_model in try/except, degrade to
None + WARNING on failure (mirroring _host_default_llm) so a misconfigured
explicit model does not crash app startup -- non-LLM memory ops still work
and an update raises at runtime with the error logged. (llm.py)
- from_backend_config unknown-key warning: log a WARNING for unknown
backend_config keys (mirrors the host layer's load_memory_config_from_dict)
so a typo like `storage_pat` does not silently fall back to the default and
write memory to an unintended location. (config.py)
Tests: rewrote 3 create_storage fallback tests to expect ValueError; added 4
tests (build_llm zero-config/degrade, from_backend_config warn/silent).
make lint green; full memory suite passes.

* feat(frontend): show real project version on About page
The About page heading was hardcoded "About DeerFlow 2.0" while the real
version is 2.1.0, kept in lockstep across backend/pyproject.toml,
frontend/package.json, and Chart.yaml by scripts/verify_versions.sh.
With the nightly workflow shipping unreleased main daily, a hardcoded
version drifts further from reality every day.
Wire the heading to the real version, nightly-aware:
- src/version.ts reads NEXT_PUBLIC_APP_VERSION (nightly override) with a
package.json fallback for release/local builds.
- about-content.ts interpolates APP_VERSION into the heading; the
"DeerFlow 1.0 and 2.0" milestone copy in acknowledgments is left as-is.
- Dockerfile adds ARG APP_VERSION / ENV NEXT_PUBLIC_APP_VERSION in the
builder stage so nightly CI can stamp the version.
- nightly.yaml computes the nightly string once in prepare
(<base>-nightly.<date>-<sha>, mirroring the chart scheme) and feeds it
to both the frontend image build-arg and the chart publish (refactored
to consume the shared output, so the displayed version and chart
version can't drift). Release builds (container.yaml) are untouched
and fall back to package.json.
Tests cover the version branches and the heading interpolation;
RELEASING.md notes the About page as a derived version consumer.
* test(frontend): assert positive About-page version value
Address review feedback on #4126: the unset-env assertion was negative-only
(checked the stale "2.0" literal was gone), so it would still pass if
APP_VERSION interpolated to "" or undefined. Mirror version.test.ts by
asserting the heading carries the real resolved APP_VERSION.
* ci(nightly): fail loudly on empty base version
Address review feedback on #4126: the prepare step's BASE (parsed from
Chart.yaml) had no empty-guard. A malformed/missing version would yield
`-nightly.<date>-<sha>` (invalid semver) that now flows into both the
chart publish and the frontend About-page version. Add `set -euo pipefail`
plus a `test -n "$BASE"` guard mirroring publish-chart. `pipefail` matters
- without it the pipeline's exit code is awk's, so `set -e` alone wouldn't
catch a grep miss.
* feat(subagents): show runtime metadata on task cards
* fix(subagents): stop task-card render loop and dedupe model fetches
Address code review on the runtime-metadata cards:
- P1 render loop: the terminal ToolMessage is re-parsed on every
MessageList render and always carries modelName/usage, so the
presence-based setTasks condition fired a fresh state object each
render -> "Maximum update depth exceeded". computeNextSubtask now
returns a value-compared `changed` flag and a pure subtaskNotification()
routes terminal transitions through the deferred after-render path
while skipping no-op re-parses.
- Per-card useModels refetch: add staleTime: Infinity to the ["models"]
query so every subtask card shares one /api/models fetch instead of
refetching on each mount.
* make format
* refactor(subagents): dedupe token-usage validators + tidy event narrowing
Address PR review follow-ups:
- DRY: extract one shared token-usage validator per side. Backend
status_contract.normalize_token_usage() now backs both the terminal
ToolMessage metadata and the subagent.step/.end run events
(step_events.py), and frontend messages/usage.normalizeTokenUsage()
backs both the live task_running event (lifecycle.ts) and the terminal
ToolMessage metadata (subtask-result.ts). Prevents the input/output/
total_tokens validation from drifting across the four former copies.
- Nit: onCustomEvent narrows event.type once instead of re-checking the
object shape per branch; the redundant task_started early-return
(already validated by taskEventToSubtaskUpdate) is dropped.
Phase 2 of #3875. Two guardrail axes can end a subagent run early — the turn
budget (GraphRecursionError) and the token budget (TokenBudgetMiddleware) —
and both now surface *why* through one additive `subagent_stop_reason` field
instead of a status enum.
This completes and course-corrects Phase 1 (#3949), which shipped the
turn-budget cap as a `max_turns_reached` status enum. The agreed Phase 2
design replaces that enum with an optional `stop_reason` field
(token_capped | turn_capped | loop_capped): a new enum value would break v1
consumers, while an additive field is ignored by older frontends and ledger
readers. `max_turns_reached` and SubagentStatus.MAX_TURNS_REACHED are removed.
- subagents.token_budget config (default enabled, 2,000,000 tokens, warn 0.7)
with per-agent override; TokenBudgetMiddleware is now attached in
build_subagent_runtime_middlewares so the cost-ceiling backstop engages for
every subagent. The hard-stop does not raise — it strips tool_calls and
lets the run finish with a final answer, recording the cap on a per-run
consume_stop_reason() accessor.
- executor.py: on normal completion it reads consume_stop_reason() and stamps
completed + token_capped when the budget fired; on GraphRecursionError it
recovers the last AIMessage partial (completed + turn_capped) or, if nothing
usable survived, failed + turn_capped. SubagentResult gains stop_reason.
- status_contract.py / contracts/subagent_status_contract.json (v2) /
frontend subtask-result.ts: additive subagent_stop_reason field, pinned by
test_status_values_match_contract / test_stop_reason_values_match_contract.
- task_tool.py + delegation_ledger.py: drop the max_turns_reached paths; the
ledger captures stop_reason and renders model-facing "capped" guidance so
the lead reuses a capped completion knowingly.
The 2,000,000-token default is deliberately loose (tighten to taste) — it
would have roughly halved the reported 4.4M burn while leaving legitimate
deep-research runs (max_turns=150) room. Subagent summarization is a follow-up.
* feat(frontend): render slash-skill activations as inline chips
Show an explicit `/skill` activation as a compact inline chip in both the
composer and the chat transcript instead of raw slash text.
- Composer: selecting a skill suggestion stores it as a removable chip
aligned inline with the textarea; the leading `/skill ` prefix is
reattached only at submit time, so the backend activation protocol is
unchanged. Backspace on an empty input or the chip's close button clears
it; history navigation is disabled while a chip is active.
- Transcript: human messages that begin with `/skill` render the skill as a
read-only chip followed by the task text.
- Add a shared `core/skills/slash.ts` (`parseSlashSkillReference` +
`resolveSlashSkillDisplay`) mirroring the backend `slash.py` gate, so the
transcript only shows a chip when the skill actually exists and is enabled.
This removes a duplicated regex/reserved-name list and keeps display
semantics consistent with backend activation.
Add unit tests for the shared slash parser and extend the chat e2e to assert
the composer still submits `/skill <task>` after showing a chip.
* chore(frontend): format chat e2e test
* refactor(skills): address slash-skill chip review feedback
Follow-up to the inline slash-skill chip PR, resolving three second-order
review findings:
- Drive the reserved-command set and skill-name grammar from a shared
contracts/slash_skill_contract.json instead of a hand-copied
"keep in sync" pair. slash.ts and slash.py now reference the fixture, and
contract tests on both sides fail CI if either drifts.
- Extract a shared SlashSkillChip so the composer and transcript chips stay
in lockstep, and normalize the off-scale /8 and /12 opacity steps to the
standard /10 and /20 tokens.
- Split HumanMessageText into a pure parse gate plus a slash-only subtree
that owns the useSkills() lookup, so a skill-enabled toggle no longer
re-renders every plain-text human turn.
Verified: frontend eslint + tsc clean, pnpm test 572 pass (incl. new
slash-contract test); backend slash contract + slash-skills tests 31 pass.
* style(tests): sort slash skill contract imports
* fix(composer): inline the slash-skill text so the chip aligns with input
Address the "composer body layout change" review on #3981 by rendering the
active skill as an inline chip in the same text flow as the prompt, rather
than a separate flex row that drifted the box model across states.
- Render the chip + prompt inside one leading-6 wrapper and edit the prompt
through a `contentEditable` span, so the chip sits inline with the first
line and long/multi-line input wraps naturally back to the container edge.
- Align the chip with `align-top`: its h-6 (24px) height matches the text
line height, so chip and first-line centers coincide exactly (measured
delta 0), fixing the chip being raised above the baseline.
- Restore the placeholder in chip mode via a `data-empty` CSS `::before`,
which also gives the empty editable span width so it is no longer treated
as hidden.
- Widen the IME helper to `HTMLElement` and route the span's keydown/paste
through the shared skill-suggestion, prompt-history, backspace-to-clear,
and IME-composition handlers so contentEditable behaves like the textarea.
- Extend chat.spec.ts to drive the inline skill editor instead of the
textarea after a chip is shown.
* style(frontend): fix composer class order formatting
* fix(composer): break long unbroken input inside the slash-skill row
The inline slash-skill editor wrapped with `break-words`
(overflow-wrap: break-word), which only moves an over-long token to the
next line before breaking it. A long unbroken string therefore started
on the line below the chip, and when the string contained a break
opportunity such as a hyphen the browser wrapped there and pushed the
remaining run to the next line, leaving a wide gap on the right.
Switch to `break-all` (word-break: break-all) so the text fills each
line from the chip and packs tightly regardless of hyphens or CJK.
* feat: add composer input polishing
* Revert "Merge branch 'main' into feat/input-polish"
This reverts commit 5b6ceccf0db3092bc62fde3b05e7816829601756, reversing
changes made to 45fbc57fef5fa5fd878cf0176c37f3e3bc7ebef6.
* Merge main into feat/input-polish
* style(frontend): format input helper polish guard
* fix(input-polish): address composer polish review findings
Frontend
- Add a cancel affordance to the in-flight polish status pill that calls
abortInputPolishRequest(), so a slow/hung provider no longer hard-locks the
composer for up to stream_chunk_timeout with a page reload (and draft loss)
as the only escape.
- Reset promptHistoryIndexRef/promptHistoryDraftRef when a rewrite is applied
(and on undo), so a stale history-browse index can no longer let the next
ArrowDown silently overwrite the polished draft.
- Disable polishing while an open human-input card is present, matching the
frontend/AGENTS.md rule that composer entry points defer to the card so
card-reply metadata is preserved.
- canPolishInput now reuses parseGoalCommand/parseCompactCommand instead of a
third hardcoded reserved-command regex, and drops the phantom /help entry
(no /help parser exists in the composer), so future builtins only need to be
taught to the existing parsers.
Backend
- Extract the non-graph one-shot LLM path (build model + inject Langfuse
metadata + system/user invoke + text extract) into
deerflow.utils.oneshot_llm.run_oneshot_llm, shared by the input-polish and
suggestions routers so tracing-metadata and invocation shape cannot drift
between the two copies.
- strip_think_blocks gains truncate_unclosed (default True, preserving the
suggestions/goal JSON-prep behavior); input polish passes False so a draft
that legitimately contains a literal <think> substring is no longer
truncated into a partial rewrite or a spurious 503.
- Validate the empty-check and max_chars boundary against the same stripped
view of the draft that is sent to the model, so the user-facing length
boundary and the model input can no longer disagree.
Tests / docs
- Backend: literal-<think> preservation, whitespace-only rejection, and
normalized-length/model-input agreement cases; suggestions tests repoint the
create_chat_model patch to the shared helper module.
- Frontend: helper unit tests updated for the /help/reserved-command change; a
new Playwright case covers cancelling an in-flight polish request.
- backend/AGENTS.md documents the shared one-shot helper and the polish
normalization/think-tag behavior.

* feat(frontend): add structured human input cards for ask_clarification
Implement a reusable Human Input Card flow for ask_clarification while keeping
the existing text fallback for older clients and IM channels.
Backend:
- Add structured ToolMessage.artifact.human_input payloads for clarification requests.
- Preserve ToolMessage.content as the readable Markdown/text fallback.
- Normalize clarification options from native lists, JSON strings, plain strings,
mixed scalar values, None, and missing options.
- Derive input_mode as choice_with_other when options exist, otherwise free_text.
- Keep disable_clarification non-interactive behavior as a plain ToolMessage with
no human_input artifact.
- Cover artifact persistence and Gateway message metadata preservation in tests.
Frontend:
- Add human input protocol types, runtime guards, extractors, response builders,
and thread-state helpers.
- Add reusable HumanInputCard with option buttons, free-text input, pending,
read-only, disabled, and answered states.
- Render structured clarification cards from artifact.human_input, with Markdown
fallback for malformed or legacy tool messages.
- Preserve line breaks in structured question/context/option text.
- Hide submitted clarification bridge messages from the chat UI via
additional_kwargs.hide_from_ui.
- Send structured human_input_response metadata through the fourth sendMessage
options argument, preserving run context in the third argument.
- Wire submissions for normal chats, custom agent chats, agent bootstrap chats,
and sidecar chats.
- Derive answered state from raw thread.messages so hidden replies still update
the original card.
- Clear pending state when the hidden reply arrives, dispatch is dropped, or a
later async stream failure appears on thread.error.
* perf(frontend): optimize HumanInputCard UI interactions

- Keep hidden card replies in memory filtering while excluding malformed/internal hidden messages
- Add regression coverage for card IME handling and hidden reply sanitization
* fix: tighten human input response validation
- Reject empty hidden human input response values
- Remove invalid list ARIA role from human input card options
- Add backend coverage for empty response payloads

* fix(sidecar): make panel button delete the side chat instead of hiding it
The side chat panel's top-right button called `sidecar.close()`, which only
hid the panel — duplicating the header `SidecarTrigger` toggle. Repurpose the
button so the panel owns deletion and the header toggle owns hide/show.
- When a conversation exists, the button shows a trash icon and opens a
confirmation dialog before deleting via `useDeleteThread` (backend cascade).
- In the draft state (references only, no thread yet) the header trigger is not
rendered, so the button falls back to a plain close (X) that discards the
draft without a confirm — there is nothing persisted to delete.
Also fix a latent double-delete bug surfaced by the new dialog:
`useDeleteThread` deletes through the LangGraph route (which drops the
thread_meta row) and then calls `deleteLocalThreadData`, which hits the same
gateway handler whose `require_existing=True` guard now 404s. Treat that 404 as
idempotent success. The recent-chat delete used fire-and-forget `mutate`, so it
swallowed this error; the sidecar's `mutateAsync` surfaced it as a toast.
The e2e mock now mirrors the gateway ownership guard (second DELETE 404s once
the thread is gone) so the regression stays covered. Adds tests for delete,
draft-state close, and header-owned hide/show.
* fix(sidecar): lock delete dialog while deletion is in flight
The delete confirmation dialog disabled Cancel during an in-flight
delete but still allowed dismissal via the overlay, Esc, and the
built-in close (X). Those paths could imply the delete was cancelled
when it was actually still running. Ignore dismissals and drop the
close button while `isDeleting` so only the (disabled) Cancel path
controls the dialog.
On conversation pages the composer renders an opaque `bg-background` strip
just below itself to mask scrolled content peeking past the rounded corners.
The strip was a child of `PromptInput`, the element that draws the focus ring.
A parent's box-shadow always paints beneath its own descendants, so the strip
covered the bottom ~3px of the ring — the blue focus outline looked cut off
along the bottom edge whenever the composer sat flush at the viewport bottom.
Move the strip out of `PromptInput` to be a sibling with a lower stacking order
and give the composer `relative z-10`, so the ring composites above the strip.
The strip still masks the same region; only the paint order changes. Welcome
mode is unaffected (it never renders the strip).
* refactor(frontend): extract placeholder detection utility with unit tests
* fix(frontend): pass prompt text directly to onSelectPlaceholder to avoid stale DOM read
The onSelectPlaceholder callback was reading textarea.value immediately
after textInput.setInput(prompt), but React state updates are async so
the DOM had not yet reflected the new value. This caused the placeholder
auto-selection to silently fail when the textarea was previously empty.
Fix: accept the new text as a parameter instead of reading from the DOM.
* fix(frontend): resolve duplicate findSuggestionTemplatePlaceholder identifier
After rebasing onto main, the function existed both inline in
input-box-helpers.ts (from #3764) and as an import from our new
placeholders module, causing TS2300 duplicate identifier errors.
- Remove duplicate import in input-box.tsx
- Replace inline function in input-box-helpers with re-export from
@/core/suggestions/placeholders
- Export SUGGESTION_TEMPLATE_PLACEHOLDER_PATTERN from placeholders module
* refactor(frontend): remove dead hasUnreplacedPlaceholder export
No production call site uses this boolean wrapper — both existing
checks need the {start,end} range from findSuggestionTemplatePlaceholder.
Drop the function and its two unit tests.
* fix(sidecar): correct text-selection toolbar actions inside the side chat
The sidecar panel reuses MessageList, but it did not distinguish the side
chat surface from the main conversation, so selecting text inside the side
chat behaved as if it were the main list:
- The "Ask in side chat" action was shown even though the user is already
in the side chat, which is a no-op interaction.
- "Add to conversation" routed the snippet to the main composer's quotes
(conversationQuotes) instead of the side chat's own composer, so the
reference landed in the wrong input box.
Add a `sidecarSurface` prop to MessageList. On the sidecar surface, hide
"Ask in side chat" and route "Add to conversation" to `sidecar.openContext`
so the snippet attaches to the side chat's own composer (activeReferences).
Main-list behavior is unchanged.
* docs(sidecar): drop AGENTS.md note for the toolbar surface change
The sidecarSurface behavior is self-evident from the code; no dedicated
Interaction Ownership entry is needed.
* fix(subagents): surface turn-budget cap as MAX_TURNS_REACHED with partial result (#3875)
Phase 2 of #3875. When a subagent exhausts its turn budget
(recursion_limit == max_turns), LangGraph raises
GraphRecursionError from agent.astream. The generic
except Exception in _aexecute misclassified it as FAILED and
discarded the partial work already streamed into final_state, so the
lead could not tell 'broken subagent' from 'out of budget' and got an
empty failure.
Catch GraphRecursionError specifically (before the generic handler)
and set a distinct SubagentStatus.MAX_TURNS_REACHED terminal status,
recovering the partial result from the last streamed chunk via a shared
_extract_final_result helper (refactored out of the normal-completion
path so both paths render content identically).
Extend the cross-language status contract so the new value travels on
additional_kwargs.subagent_status: a capped run is result-bearing, so
make_subagent_additional_kwargs / read_subagent_result_metadata
carry subagent_result_brief + subagent_result_sha256 (the
recovered work, like completed) AND the cap notice on subagent_error
-- the one status that carries both. task_tool.py returns it via the
shared _task_result_command; the delegation ledger prefers the
partial result_brief and renders model-facing guidance (reuse / retry
tighter / raise max_turns). Frontend collapses max_turns_reached to the
failed pill with the cap notice on error.
No agent-loop, runner, or persistence behavior touched; default
max_turns is unchanged.
* refactor(subagents): consolidate content-stringify onto shared helper
Address review feedback on #3949 (willem-bd, copilot-pull-request-reviewer):
- executor.py: drop the private `_stringify_message_content` — a third
near-duplicate of `utils/messages.py::message_content_to_text`.
`_extract_final_result` now delegates to that canonical helper; the
"No response generated" sentinel is pushed down to the consumer (the
shared helper returns "" for no-text, matching every other call site).
- task_tool.py: align the live `task_failed` event's error string with
the canonical "Reached max_turns=N" used by the logger, the structured
`error=`, and the executor (was "Reached max turns (N)").
Behavior for real AIMessage content is unchanged; only atypical edge inputs
(consecutive bare-string list items; empty content) now match the canonical
helper that every other call site already uses.
`extract_response_text` is intentionally left as-is: it filters by OpenAI
content-block `type`, a different shape with many callers and its own tests.

Workspace files are not checkpointed, so cloning them onto a branch

* fix(frontend): address mobile workspace polish blockers
* fix(frontend): prevent mobile landing overflow
* fix(frontend): keep landing sections within mobile viewport
Section titles used a fixed text-5xl with no word breaking, and the
<section> flex items had default min-width:auto, so wider Linux font
metrics in CI pushed content past the viewport (scrollWidth 345 > 320).
Make titles/subtitles responsive with break-words, constrain section
width with min-w-0, and add an overflow-x-clip guard on the page root.
* fix(frontend): address review feedback on mobile landing PR
- add hamburger Sheet nav below sm: so mobile users keep docs/blog access

- memoize artifactContent so it isn't rebuilt on every streamed token
- use slot-based key in HeroWordRotate; drop flex-wrap so SuperAgent never orphans at 320px
- delete unused word-rotate.tsx dead code
- move section gutter to <main> for a uniform mobile padding contract
- harden e2e: per-viewport overflow tests, locale-stable artifact selector, focus-ring asserts light vs dark differ
