* 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
- Support Enter key to submit text input (Shift+Enter for newline)
- Render question and context fields as Markdown instead of plain text
- Replace deprecated FormEventHandler type with structural typing
* test(frontend): add unit test cover optimize HumanInputCard UI interactions
* feat(frontend): disabled chatbox when has new human-input-card
* fix(style): lint error fix
* fix: sanitize hidden human input replies
- Preserve IME composition safety for human input card Enter submits
- Treat hidden human input responses as genuine user messages for sanitization
- 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.
* feat: add assistant turn branching
* fix(threads): skip workspace clone when branching from historical turn
Workspace files are not checkpointed, so cloning them onto a branch
rooted at an older assistant turn leaked files created in a later
timeline. Restrict the best-effort workspace copy to branches taken from
the latest turn; historical-turn branches now report
workspace_clone_mode="skipped_historical_turn" and keep only the
restored message history.
* style(frontend): fix prettier formatting in e2e mock-api
Collapse the branch-title normalization chain onto a single line to
satisfy the frontend lint (prettier --check) CI gate.

* 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
- switch useIsMobile to useSyncExternalStore to avoid hydration swap flash
- 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

* fix(frontend): gate workspace change badge to assistant messages
Only pass run_id to assistant MessageListItems so the workspace-change

run_id. Assert single badge render in the E2E flow.
* fix(workspace-changes): address review feedback on diff parsing and badge
- Restrict unified-diff header detection to "+++ "/"--- " (trailing space)
in both backend _count_diff_lines and frontend getWorkspaceChangeLineClass
so content lines beginning with +++/--- are counted/styled correctly
- Gate WorkspaceChangeBadge to ai messages so tool messages folded into an
assistant group don't render a duplicate badge
- Add regression tests for both diff-classification fixes
- Apply prettier formatting to workspace-changes files flagged by CI

* feat(frontend): add side conversations for quoted follow-ups
* style(frontend): apply prettier formatting to sidecar-chat files
* fix(frontend): surface sidecar cascade cleanup failures via console.warn
Previously deleteSidecarThreadsForParent silently swallowed both
lookup errors and per-thread deletion failures, so parent thread
deletions could succeed while orphaning sidecar threads with no
signal to the caller. Log a warning that includes the parent id
and the failed thread ids/reasons so the leak is discoverable in
telemetry, matching the existing console.warn/error pattern in
this file.
* fix(frontend): address all sidecar review feedback
Resolve every reviewer comment on PR #3934:
- input-box/hooks/sidecar-panel: clear quoted references only via an
`onSent` callback that fires after the in-flight guard, so a dropped
send no longer silently discards quotes (willem-bd #3550).
- message-list: flip the selection toolbar below the selection when it
would clip above the viewport (willem-bd #3551).
- reference-metadata/thread/input-box: keep referenced ids, roles, and
count arrays 1:1 parallel instead of deduping ids (willem-bd #3552).
- message-list: widen selection containment to the shared assistant-turn
container and hint when a selection crosses messages (willem-bd #3553).
- sidecar/api: coalesce concurrent sidecar creates for one parent behind
a single in-flight promise to prevent duplicates (willem-bd #3554).
- sidecar-trigger/context: force-restore on trigger click so a sidecar
deleted elsewhere self-heals instead of opening a dead thread
(willem-bd #3555).
- threads/hooks: surface sidecar cascade cleanup failures via
console.warn for both lookup and per-thread deletes (Copilot).
Add unit + e2e coverage for parallel metadata, atomic create, and
trigger self-healing.
* feat: add scheduled tasks MVP
* fix: harden scheduled task execution semantics
* feat(scheduled-tasks): preset-driven schedule form with timezone and live preview
Replace the raw cron input with a preset Select (hourly/daily/weekly/monthly/custom)
plus structured inputs (time picker, weekday toggles, day-of-month), datetime-local
for one-time tasks, a timezone selector defaulting to the browser timezone, and a
live human-readable preview. Reuses one ScheduledTaskScheduleInput for create and
edit; backend contract unchanged; zero new deps (pure Intl + DST-safe offset helpers).
* feat(scheduled-tasks): full-page i18n + recipe templates + E2E locale pin
Localize the rest of the scheduled-tasks page (filters, detail pane, actions,
edit form, run list, enum values) via t.scheduledTasks.* in en/zh. Add four
built-in recipe templates (GitHub Trending, news digest, issue triage, weekly
report) exposed as a chip row that pre-fills title + prompt + schedule. Pin
Playwright locale to en-US so E2E selectors stay stable against i18n. No backend
change, no new deps.
* fix(scheduled-tasks): idempotent 0003 migration, update head constants, future-date once test
Merge with main surfaced three CI failures:
- 0003_scheduled_tasks create_table collided with legacy test seeds that
build from full metadata; guard with inspector.has_table so the revision
no-ops when the table already exists (0004/0005 are already idempotent via
_helpers.py).
- persistence bootstrap concurrency/regression tests pinned HEAD to main's
0002_runs_token_usage; bump to the new head 0005_scheduled_task_thread_nullable.
- once-task router test used a fixed past run_at and tripped the
must-be-in-the-future validation; use a future date.
* address review: ok-check, 502 for trigger failure, mock fields, migration filename, doc fences
- fetchThreadScheduledTasks now checks response.ok like the other fetchers.
- trigger endpoint returns 502 (not 409) when dispatch fails outright, so
clients can distinguish a real conflict from a server-side failure.
- E2E mock normalizes scheduled-task objects with context_mode/last_thread_id
and nullable thread_id, matching the backend contract the UI renders against.
- Rename 0002_scheduled_tasks.py -> 0003_scheduled_tasks.py to match its
revision id (file was renamed in spirit already; filename now follows).
- CONFIGURATION.md: close the Tool Groups yaml fence and drop the stray fence
after the Scheduler notes so the sections render correctly.
* fix(scheduled-tasks): harden lease, poller, config, and frontend UX after review
* fix(scheduled-tasks): harden run lifecycle, overlap skip, non_interactive gating, and DST conversion after review
- defer a once task's terminal status to the run-completion hook; the task
stays running until the real outcome, and a startup sweep cancels once
tasks orphaned by a crash (launch-time 'completed' could stick forever)
- record interrupted runs as a distinct 'interrupted' run status with a
readable message; an interrupted once task ends 'cancelled', not 'failed'
- enforce overlap_policy=skip for fresh_thread_per_run via an active-run
pre-check (same-thread ConflictError can never fire across fresh threads)
- protect terminal run statuses from the late launch-path 'running' write
- honor context.non_interactive only for internally-authenticated callers;
arbitrary clients can no longer strip ask_clarification
- fix DST-stale timezone offset in zonedLocalToUtcIso by re-deriving the
offset at the resolved instant (once tasks fired an hour late around
spring-forward and the create->edit round-trip diverged)
- drop dead ScheduledTaskRunRepository.update_by_run_id; share one Gateway
API error helper between channels and scheduled-tasks frontends
* fix(scheduled-tasks): close review round-3 gaps in guards, concurrency, and API ergonomics
- scrub internal-only context keys (non_interactive) from the assembled run
config for non-internal callers: gating body.context alone left the same
key smuggle-able through the free-form body.config copied verbatim by
build_run_config
- guard update_after_launch with protect_terminal so the launch bookkeeping
write cannot clobber a once task already finalized by a fast-failing run's
completion hook (parent-row sibling of the run-row guard)
- reject a manual trigger while the task has an active run (409) instead of
launching a duplicate concurrent run on fresh_thread_per_run
- re-arm a terminal once task to enabled when PATCH pushes run_at into the
future; previously the endpoint returned 200 with a next_run_at that could
never be claimed
- make max_concurrent_runs a real global cap: each poll claims only into the
remaining budget of active (queued/running) scheduled runs
- paginate GET /scheduled-tasks/{id}/runs (limit<=200, offset) and push the
thread filter of /threads/{id}/scheduled-tasks into SQL
- stamp context.user_id on scheduler-launched runs, matching IM channels, so
user-scoped guardrail providers see the owning user

* feat(frontend): add citation sources evidence panel
Inline [citation:Title](URL) links render as badges, but with many
citations the reader has no consolidated, deduplicated list of what a
message or report actually drew on. Add a collapsible "sources" panel
that extracts citation links from AI messages and markdown artifacts,
dedupes by URL, counts occurrences, and offers per-source copy of a
reusable markdown reference.
- extractCitationSources: parse [citation:...](url) links, skip images
and fenced code, dedupe by normalized URL, fall back to domain for
generic labels
- CitationSourcesPanel: collapsible list with per-source cite counts,
internal scroll for long lists, and copy-to-clipboard reference button
- Wire panel into AI message content and markdown artifact preview
- Add en-US/zh-CN citation strings and types
- Unit tests for extraction and panel rendering
* fix(frontend): preserve default link styling in message content override
MessageContent_ passes a custom `a` renderer to MarkdownContent, whose
default `a` (primary underline + external target/rel) is overridden
because MarkdownContent spreads props components last. Restore that
styling/external behavior in the fallback branch so normal links in
messages aren't regressed, while keeping citation: and /mnt/ handling.
* fix(frontend): harden citation source extraction and dedupe link renderer
Address review findings on the citation sources panel:
- Use a non-consuming lookbehind so back-to-back citations no longer drop
every other source.
- Match balanced parenthetical groups in URLs so disambiguation links like
.../Foo_(a)_(b) are no longer truncated.
- Mask inline code (and unclosed streaming fences) so example citations in
code aren't scraped as real sources; masking preserves indices.
- Extract a shared createMarkdownLinkComponent factory used by both message
content and markdown content, removing the duplicated `a` renderer.
* implement goal continuations
* fix(goal): address review findings for goal continuations
- goal: key the no-progress breaker on a signature of the latest visible
assistant evidence instead of the evaluator's volatile free-text, so it
actually fires on stalled turns; thread the signature through every
worker persist / no-progress call site
- goal: align _stand_down_reason default caps with should_continue_goal
(8 / 2) so the two gate functions agree on goals missing the fields
- runtime: offload the synchronous checkpointer fallback via
asyncio.to_thread (goal.py + worker.py) to keep blocking IO off the loop
- frontend: i18n the GoalStatus "Goal" label (goalLabel in en/zh/types)
- frontend: extract pure composer helpers into input-box-helpers.ts with
unit tests (parseGoalCommand, readGoalResponseError, skill suggestions)
- tests: cover the evidence-based no-progress and default-cap behavior
- docs: align backend/AGENTS.md goal paragraph with actual behavior
- e2e: prettier-format chat.spec.ts (fixes the lint-frontend CI failure)

* feat(frontend): hide goal continuation counter until the agent continues
The goal status bar rendered a raw "0/8" before any auto-continuation, which
read as a mysterious score. Now the counter is hidden until
continuation_count > 0, then shows "Continuing N/M" with a tooltip explaining
the auto-continuation cap.
- Extract getGoalContinuationDisplay into a pure helper (hides at 0) + unit tests
- Add goalContinuing / goalContinuationTooltip i18n keys (en/zh/types)
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(goal): address review findings for goal continuations
Frontend correctness
- Fix the optimistic /goal result permanently shadowing server goal state:
the streamed continuation counter never surfaced for a goal set in-session.
Extract a shared useActiveGoal hook (used by both chat pages) that reconciles
the optimistic copy with server state via a goalReconciliationKey, de-duping
the copy-pasted goal block across the two pages.
- Stop /goal status|clear failures from escaping handleSubmit as unhandled
rejections (handleGoalCommand now returns success; the run only starts when a
goal was actually saved).
- Use a function replacer for the goal-status toast so an objective containing
$&/$1 isn't treated as a replacement pattern.
Backend cleanliness / correctness
- De-duplicate four byte-identical helpers (_call_checkpointer_method,
_message_type, _additional_kwargs, _is_visible_message) by importing them
from runtime.goal instead of re-defining them in the run worker.
- Remove the dead `checkpoint_tuple.tasks` durability guard (CheckpointTuple has
no tasks field) and document that pending_writes is the durability signal.
- Decompose the 176-line _prepare_goal_continuation_input: extract
_reread_goal_and_checkpoint and a _persist closure so the thread-unchanged
guard and stand-down persistence aren't open-coded three times. Document the
last-writer-wins write-window limitation as a follow-up.
- Add a shared parse_goal_command helper and use it from the TUI and IM-channel
/goal handlers (one place for the status/clear/set semantics).
Tests
- Restore the 11 command-registry tests dropped by the previous goal change
(filter_commands ranking/description, build_registry builtins/skills, resolve
cases) alongside the new goal tests.
- Add coverage for the IM-channel _handle_goal_command, the TUI _handle_goal
handler, parse_goal_command, and goalReconciliationKey.

The disabled panel previously said 'Set agents_api.enabled: true in

(matching the existing nameStepApiDisabledError copy). e2e now asserts the
contact-admin message and that no config.yaml/agents_api text is rendered.

* fix(agents): keep agents_api flag sticky during /api/features outage (#3757)
Failing open re-mounted the agents UI and re-triggered the 403 storm when
agents_api was genuinely disabled and /api/features was down. Persist the
last definitive answer and fall back to it (sticky) before failing open,
only failing open when nothing has ever been observed. Read the cached
value after mount so the first client render matches the server (no
hydration mismatch on the non-loading-gated sidebar).
* fix(sidebar): make disabled Agents entry keyboard/SR accessible (#3757)
The disabled-state explanation was hover-only: tabIndex={-1} removed the
entry from the tab order and the reason lived only in a pointer-triggered
tooltip. Keep it in the tab order and wire aria-describedby to a
visually-hidden reason so keyboard and screen-reader users learn why it is
disabled.

* fix(gateway): require admin for global skills management endpoints
The skills router exposed its management endpoints with no authorization
check (only Depends(get_config)), while the MCP router guards the
equivalent global extensions_config mutations with require_admin_user
(added in the #3425 security hardening). Skills storage is global/shared
across users (no per-user path), lives in the same extensions_config.json
as MCP servers, and custom skill SKILL.md content is injected into every
user's agent system prompt. Any authenticated non-admin user could mutate
or read global skills that affect all tenants:
- POST /api/skills/install: install from an arbitrary thread_id, writing
into the global custom skills tree
- PUT /api/skills/custom/{skill_name}: rewrite a global skill, injecting
instructions into all users' agent prompts (cross-tenant prompt injection)
- DELETE /api/skills/custom/{skill_name} and rollback: tamper with global skills
- GET /api/skills/custom, GET .../{skill_name}, GET .../history: read raw
global custom skill bodies/history
- PUT /api/skills/{skill_name} (enable toggle): writes the shared
extensions_config.json and refreshes the system prompt for every tenant,
so a non-admin could enable/disable any skill globally. There is no
per-user skill state, so this is a global mutation, not a preference.
Add require_admin_user to every endpoint above, mirroring the MCP router.
The shared read path used internally by update/rollback was extracted into
a non-auth helper (_read_custom_skill_response) so internal reuse does not
double-check auth.
Only the read-only GET /api/skills and GET /api/skills/{skill_name} stay
open to normal users: they return just name/description/enabled and back
the user-facing settings UI.
Tests:
- New tests/test_skills_router_authz.py: a non-admin user gets 403 on every
guarded endpoint (including the enable toggle); basic listing stays open;
admins can still toggle.
- Update tests/test_skills_custom_router.py to authenticate as admin.
- pytest tests/ -k skill -> 350 passed, 1 skipped; ruff clean.

* fix(frontend): gate skill enable/install UI behind admin + handle 403
Follow-up to the backend change that made the global skills mutations
admin-only. Without a matching UI change, a non-admin user would hit a
silent 403 when toggling a skill in Settings -> Skills or clicking
"Install skill" on a .skill artifact.
- core/skills/api.ts: add SkillRequestError (status + isAdminRequired),
throw it from loadSkills/enableSkill on non-ok responses and from
installSkill on 403 (other install errors keep the soft-failure
contract).
- core/skills/hooks.ts: useSkills no longer retries on SkillRequestError.
- skill-settings-page.tsx: show an "admin required" message on 403, and
disable the enable toggle for non-admins (mirrors the MCP tools page).
- artifact-file-detail.tsx / artifact-file-list.tsx: only render the
"Install skill" action for admins, and surface an admin-required toast
if a 403 still occurs.
- i18n: add settings.skills.adminRequired / installAdminRequired (en + zh).
Auth/no-auth and static-website modes synthesize an admin user, so these
gates do not affect single-user/local deployments.
Verified locally: pnpm check (eslint + tsc) passes with no new errors,
pnpm build succeeds, and the dev server renders / and /login (200) with
no compile/runtime errors.

* feat(subagents): persist and display subagent step history (#3779)
Capture both assistant turns and tool outputs during subagent execution,
stream them in task_running events, and persist them as subagent.* run
events so the subtask card's step timeline survives a reload.
Backend:
- step_events.py: pure layer (capture_step_message, build_subagent_step,
subagent_run_event) shared by streaming and persistence
- executor.py: capture ToolMessage outputs, not just AIMessage turns
- worker.py: persist task_* custom events to RunEventStore (category
"subagent" keeps them out of the thread feed; list_events backfills)
Frontend:
- core/tasks/steps.ts + api.ts: SubtaskStep model, messageToStep,
eventsToSteps, mergeSteps, fetchSubtaskSteps
- subtask card accumulates live steps and backfills on expand
- carry run_id onto history content messages for the events endpoint
* fix(subagents): show AI turns in subtask card + paginate step backfill (#3779)
Two follow-ups to the subagent step-history feature:
Problem 1 — reload backfill could silently truncate the step timeline because
list_events capped at 500 events (seq-ASC) across the whole run. Add task_id
filtering + an after_seq forward cursor to list_events (all three stores +
abstract base + the /events route), and make fetchSubtaskSteps page through one
task's subagent.step events until a short page. No schema migration: the DB
filter rides the existing run-scoped index via event_metadata["task_id"].
Problem 2 — the card only rendered tool steps, so persisted AI turns were never
shown. Replace toolStepsForDisplay with stepsForDisplay: interleave AI reasoning
turns (with text) and tool steps by message_index, drop blank-text AI turns, and
drop the trailing final-answer AI turn when completed (already shown as result).
Card renders AI steps as muted clamped markdown with a sparkles icon.
Tests: store task_id/after_seq filtering + pagination across memory/db/jsonl,
the /events route forwarding, stepsForDisplay rules, and fetchSubtaskSteps
pagination. Docs updated in both AGENTS.md.
* make format
* fix(subagents): capture full multi-tool step tail, batch step persistence, cap tool-call args (#3779)
Address PR review findings on the subagent step-history feature:
1. executor.py streamed on stream_mode="values" and captured only
messages[-1] per chunk, so a multi-tool-call turn (ToolNode appends
one ToolMessage per call in a single super-step) lost all but the last
tool output in both the live task_running stream and the persisted
history. Replace with capture_new_step_messages, which walks the
newly-appended tail (and still re-checks the trailing message on
no-growth chunks so id-less in-place replacements survive).
2. worker.py persisted each step with the store's low-frequency put()
(a per-thread advisory lock per call); a deep subagent (max_turns=150)
emits hundreds of steps on the hot stream loop. Replace with
_SubagentEventBuffer, which batches via put_batch (flush on terminal
subagent.end, at FLUSH_THRESHOLD, and in the worker finally).
3. build_subagent_step capped only text; tool_calls[].args were copied
verbatim, so a large write_file/bash payload produced an unbounded
subagent.step row. Cap each call's serialized args at
SUBAGENT_STEP_MAX_CHARS, flagged args_truncated.
Tests updated/added for all three; AGENTS.md refreshed.
* fix(subagents): merge backfill into latest subtask state; reuse message_content_to_text (#3779)
Address the remaining two PR review findings:
4. subtask-card's fetchSubtaskSteps().then(updateSubtask) closed over a
stale tasks snapshot: a late-resolving backfill wrote setTasks({...stale}),
clobbering SSE steps/status and sibling subtasks that arrived during the
fetch. useUpdateSubtask now reads/writes through a tasksRef mirroring the
latest state (ref-to-latest), and the pure per-subtask transition is
extracted to core/tasks/subtask-update.ts::computeNextSubtask (unit-tested).
5. step_events._content_to_text duplicated deerflow.utils.messages.
message_content_to_text; call the shared helper instead (guarding None
content with 'or ""' so a tool-call-only turn still renders as "").
Tests added for computeNextSubtask and the None-content case; AGENTS.md docs updated.
Closes#3192
Root cause
----------
The artifact preview header is driven by a Radix Select whose <SelectValue>
renders the label of the <SelectItem> matching the current value. The option
list was built solely from `artifacts` in ArtifactsContext, which is only
synced from `thread.values.artifacts` (chat-box.tsx). Artifacts surfaced via
the message-layer `present_files` tool call are never written back to
`thread.values.artifacts`, so when such a file is selected its filepath has
no matching <SelectItem>. Radix then renders an empty trigger and the header
filename appears blank, even though the preview body loads correctly.
Fix
---
Compute `artifactOptions` as a defensive union: if the currently selected
filepath is missing from `artifacts`, prepend it so a matching <SelectItem>
always exists. This keeps the header label in sync with the active file
without changing context semantics or coupling the UI to a future
auto-discovery mechanism (see existing TODO in chat-box.tsx).
Tests
-----
Add an e2e case that mocks a thread whose only artifact is delivered via
`present_files` (thread.values.artifacts = []) and asserts both the header
title and preview content render. All 21 e2e tests pass.
* fix(frontend): improve chat math rendering

itself is escaped.
- Thread inInlineCode state across lines so multi-line backtick code
spans are protected from delimiter conversion.
- Remove double math normalization: preprocessStreamdownMarkdown now
only handles Mermaid; math normalization lives solely in
ClipboardSafeStreamdown, preventing non-idempotent double passes.

Streamdown's streaming-incomplete-math handling is actually active
during streaming.

* fix(frontend): reset new chat on client-side navigation
Drive the chat reset effect with Next.js's reactive pathname instead of the render-time window.location-derived flag.

* fix(frontend): resolve stale subagent running state after stop
Subtask cards were recreated from task tool calls as in_progress whenever
the thread was loading. If a user stopped a run before the task tool returned
a ToolMessage, the card could remain running after reload, and could flip back
to running when a later user turn started streaming.
Derive pending subtask state from the current assistant turn instead of the
global thread loading flag. A task now stays in progress only while its own
turn is loading or while a matching ToolMessage exists for result parsing;
otherwise it is marked failed.
Add unit coverage for task ToolMessage matching and for the later-turn loading
regression.
* fix(frontend): refresh subagent card on terminal status transition
- notify React via a ref + post-render effect when a subtask flips to
completed/failed, so SubtaskCard updates without relying on an
unrelated MessageList re-render
- tighten the current-turn heuristic to `groupIndex === lastGroupIndex`
(precomputed once) — fixes the rare case where an earlier subagent
group in the same turn was kept in_progress, and drops the per-group
slice+some scan to O(1)
- rename `getPendingSubtaskStatus` → `derivePendingSubtaskStatus`
- narrow `toolCall.id` at MessageList call sites; skip task tool calls
without an id instead of `id!`
- add Playwright e2e covering reload-after-stop showing `Subtask failed`
* fix(channels): make runtime provider state authoritative
* make format
* fix(channels): close runtime provider config races and status gaps
Address review findings on the runtime-provider-state change:
- configure/disconnect now re-read the live app.state.channels_config
after the worker await and mutate only the affected provider key in
place, so a concurrent mutation for a different provider is no longer
clobbered by a stale pre-await snapshot.
- disconnect revokes DB connection rows before committing the store and
cache, so a repo failure cannot leave the store/cache "disconnected"
while the DB keeps "connected" rows a later re-configure would
silently reactivate.
- _provider_response preserves non-connected statuses (e.g. revoked)
when the provider is unavailable, only masking a stale "connected"
row as not_connected.

GET /api/mcp/config returns 403 for non-admin users, but the previous
client returned the error body as MCPConfig, causing MCPServerList to
crash with 'Cannot convert undefined or null to object' on
Object.entries(config.mcp_servers).
- api.ts: introduce MCPConfigRequestError; loadMCPConfig and
updateMCPConfig now throw it (carrying status + isAdminRequired)
instead of letting non-2xx bodies leak through as parsed config
- tool-settings-page.tsx: render a friendly 'admin privileges required'
empty state when the React Query error is an admin-required
MCPConfigRequestError; keep MCPServerList resilient with
Object.entries(servers ?? {}) and an empty-state for no servers
- i18n: add settings.tools.adminRequired and settings.tools.empty in
en-US, zh-CN and the Translations type
- tests: cover 403 / 5xx / instanceof / detail-fallback for both
loadMCPConfig and updateMCPConfig in tests/unit/core/mcp/api.test.ts
Refs: #3527
* fix(frontend): render user messages as plain text and cap blockquote nesting
User messages are typed or pasted plain text, not authored Markdown, but
they were rendered through the full Streamdown pipeline. Pasted source
files got fragmented (indented chunks become code blocks, paragraphs
collapse and lose indentation), "$...$" spans were KaTeX-ified, and a
message with thousands of nested ">" markers overflowed the call stack
in marked's recursive blockquote lexer, permanently crashing the thread
on every load.
Render human message content verbatim with pre-wrap instead, and cap
blockquote nesting at 100 levels at the Streamdown chokepoint so model
output cannot trigger the same recursion either.
Closes#3500
* fix(frontend): absorb marked lexer crashes with a render fallback boundary
Review found two gaps in the nesting cap: marked's list and blockquote
tokenizers are mutually recursive, so a list marker in front of the
quote chain ("- > > > ...") bypassed the blockquote-only regex and
still overflowed the stack; and the line-based rewrite was fence-blind,
silently truncating literal ">" runs inside code blocks.
Add an error boundary around Streamdown that renders the raw content as
plain pre-wrap text when rendering throws (retrying on the next content
change), keep the cap as a fast path for the dominant pure-">" case,
and make it skip fenced and indented code lines.

Frontend connect flow:
- Open the runtime-config dialog only when a provider still needs
credentials; configured providers go straight to the connect flow, so
the binding-code/deep-link path is reachable from the UI again.
- After saving credentials, continue into the connect flow when a user
binding is still required (multi-user mode) instead of stopping at a
"Connected" toast.
- Extract shared provider-state helpers to core/channels/provider-state
and add unit + e2e coverage for the direct-connect and
configure-then-connect paths.
Provider status semantics:
- Report connection_status from the user's newest connection row;
with no binding it is not_connected, except in auth-disabled local
mode where a configured running channel is effectively connected.
Concurrency and event-loop correctness:
- Offload ChannelRuntimeConfigStore construction and writes, channel
service construction, and Slack connection replies to threads; add a
tests/blocking_io/ anchor for the runtime-config handlers.
- Consume binding codes with a conditional UPDATE so a code can only be
used once under concurrent workers; retry upsert_connection as an
update when a concurrent insert wins the unique constraint.
- Serialize ensure_channel_ready per channel so concurrent provider
polls cannot double-start a channel worker.
Config and migration hardening:
- Stop mutating the get_app_config()-cached Telegram provider config;
the runtime store now owns the UI-entered bot username.
- Register channel_connections in STARTUP_ONLY_FIELDS with the
standardized startup-only Field description.
- Match the legacy unsafe-id bucket by recomputing its exact SHA-1 name
so another user's same-prefix bucket can never be migrated.
- Remove the unused Telegram process_webhook_update path and document
src/core/channels in the frontend docs.

* Address PR review comments on authz scoping and channel runtime
Security (review feedback from ShenAC-SAC):
- Scope internal-token callers to the connection owner carried in
X-DeerFlow-Owner-User-Id instead of bypassing owner checks outright,
in both require_permission(owner_check=True) and the stateless run
endpoints. Internal callers keep access to their own and
shared/legacy threads, and may claim a default-owned channel thread
for its real owner, but a leaked internal token no longer grants
cross-user thread access.
- Require admin privileges for POST/DELETE /api/channels/{provider}/
runtime-config: runtime credentials and channel workers are
instance-wide shared state (same model as the MCP config API).
Read-only provider listing stays available to all users.
Performance (review feedback from willem-bd):
- Skip the redundant thread channel-metadata PATCH after the first
successful backfill per thread.
- Reuse the per-connection Slack WebClient until its token changes
instead of constructing one per outbound message.
- Reconcile channel readiness for all providers concurrently in
GET /api/channels/providers.
Also resolve the code-quality unused-import flag in the blocking-io
anchor by pre-importing the channel service via importlib.

* Reconcile UI runtime channel config with config reload on restart
Main now reloads a channel's config.yaml entry on restart_channel()
(#3514, issue #3497). Adapt the user-owned connection flow to coexist:
- configure_channel() restarts with reload_config=False — the caller
just supplied the authoritative config (browser-entered credentials
that are never written to config.yaml), so a file reload must not
clobber it with the stale on-disk entry.
- _load_channel_config() re-applies the UI runtime-store overlay used
at startup, so an operator-triggered restart keeps browser-entered
credentials for channels without a config.yaml entry and does not
resurrect a channel disconnected from the UI.
- Offload the reload's disk IO (config.yaml + runtime store) with
asyncio.to_thread, matching the blocking-IO policy on this branch.

* fix(frontend): keep workspace interactive when SSR auth probe cannot reach gateway (#3493)
When the SSR auth probe at /api/v1/auth/me times out or fails, the
workspace layout used to render a static fallback page without
AuthProvider or QueryClientProvider, making logout and every other
interaction non-functional until the gateway recovered.
Render the normal WorkspaceContent in 'gateway_unavailable' mode
instead, surfacing a polite offline banner that re-probes the gateway
in the background and hides itself the moment refreshUser() returns
an authenticated user. The probe is reentrancy-guarded so a slow
gateway cannot pile up parallel /auth/me requests.
Closes#3493
* fix(workspace): silent probe in offline banner to avoid /login redirect during gateway recovery (#3493)
The banner previously delegated retry probes to AuthProvider.refreshUser(),
which treats any 401 from /api/v1/auth/me as 'session expired' and
force-redirects to /login. During gateway recovery, the first few requests
may transiently return 401 before the gateway is fully ready, which would
incorrectly kick the user out — defeating the purpose of the offline banner.
Now the banner silently fetches /api/v1/auth/me itself and only delegates
to refreshUser() on 200 OK. Non-200 responses (401 / 5xx / network) are
swallowed and retried on the next interval tick, ensuring the user stays
logged in across short gateway outages.
Verified in Docker:
- docker pause deer-flow-gateway → banner appears, page interactive
- docker unpause deer-flow-gateway → banner auto-disappears within 10s,
user remains on /workspace/chats/new with full session restored
- All 117 unit tests pass
* fix(workspace): fix banner polling leak and persistent 401 handling (#3493)
- Stop polling immediately after user recovery: add user to effect dependencies, cleanup interval when user !== null
- Handle persistent 401: trigger login redirect after 3 consecutive unauthorized responses
- Extract decision logic to pure helper, add 8 unit tests covering all critical paths
* fix(workspace): address CR feedback on gateway offline recovery (#3493)
- gateway-offline-banner-helpers: decrement (not reset) auth-failure
streak on transient outcomes so a flapping gateway (401 alternating
with 5xx) still converges on session-expired
- gateway-offline-banner: reuse probe response body to apply user
directly via new AuthProvider.applyUser, halving the recovery burst
against an already-struggling gateway
- gateway-offline-banner: extract classifyProbe into helpers for unit
testability; log probe failures via console.warn instead of swallowing
- gateway-offline-fallback: new shared component used by both workspace
and (auth) layouts so auth pages recover the same way the workspace
does, fixing the lockup where bare static HTML had no AuthProvider
- AuthProvider.logout: fall back to hard navigation when the gateway
logout fetch fails, matching legacy form-POST behaviour and avoiding
stale client state during outage
- tests: extend gateway-offline-banner-helpers.test with flapping
convergence and classifyProbe branch coverage (19 cases total)
* fix(frontend): paginate workspace chat list beyond 50 threads (#3482)
The sidebar 'Recent chats' and /workspace/chats list were hard-capped
at the first 50 threads returned by threads.search. Replace the
single-shot useThreads() consumers with useInfiniteThreads() and add
an IntersectionObserver sentinel to each list so further pages are
fetched on demand.
In search mode on the chats page, the sentinel is replaced by an
explicit 'Load more' button to prevent the observer from draining the
entire backend list while the filtered view stays empty.
- Add useInfiniteThreads + page-size constant and pure cache helpers
(map/filterInfiniteThreadsCache, getInfiniteThreadsNextPageParam)
- Mirror rename / delete / stream-finish updates into the new
infinite cache so optimistic UI stays consistent
- Extend the e2e mock to honour limit/offset slicing
- Unit tests for the cache helpers and pagination boundary
- Playwright e2e covering chats page + sidebar load-more, and the
search-mode guard against runaway auto-pagination
- Add en/zh i18n entries for the search-mode load-more button
Fixes#3482
* docs(frontend): clarify infinite-threads offset semantics and test post-delete invariant
- Add docstring to getInfiniteThreadsNextPageParam explaining that TanStack
Query freezes the returned offset into pageParams once, so optimistic cache
mutations that shrink page lengths (filterInfiniteThreadsCache on delete)
cannot retroactively move the offset backwards. Delete/rename paths
reconcile against the backend via invalidateQueries in onSettled.
- Add unit test covering the post-delete invariant.
- Fix misleading comment in thread-list-infinite-scroll.spec.ts: the
thread-search mock does not sort by updated_at; it returns the array in
the order provided.
Addresses Copilot CR comments on #3485.
* fix(frontend): mirror onCreated upsert into infinite cache; add sidebar Load-older button
Address review feedback on #3485:
- New upsertThreadInInfiniteCache helper; useThreadStream onCreated now
upserts into both the legacy ['threads','search'] cache and the new
infinite cache, so a freshly created thread appears in the sidebar
immediately during streaming instead of only after the run finishes
and onSettled invalidates the query. Restores parity with main.
- Sidebar Recent Chats now exposes a visible 'Load older chats' button
alongside the IntersectionObserver sentinel, so keyboard-only users
and environments where IO is unavailable can still reach older
conversations.
- Add zh-CN / en-US / types entry for chats.loadOlderChats.
- Cover the new helper with 3 unit tests (no-op on uninitialised cache,
prepend new thread to first page, merge with existing entry without
duplication).
The search input, filter tabs, and four action buttons were crammed into
a single horizontal row, which squeezed the search box into an unusable
sliver and truncated the "Summaries" filter tab to "Summarie".
Split the toolbar into two rows: search + filter tabs on the first,
actions on the second. The search input now keeps a usable min width,
filter tabs use whitespace-nowrap so they never truncate, and the
destructive "Clear all memory" button is pushed to the far right
(ml-auto) to separate it from the constructive actions.

* fix(frontend): truncate overflowing text in agent cards
Long custom agent names, descriptions, skills and tool-group labels
overflowed the agent card and broke its layout (issue #3389). The title
already had `truncate`, but it never took effect: an ancestor flex
container lacked `min-w-0`, so the flex item refused to shrink below its
content width.
- Restore the truncation chain by adding `min-w-0` to the title's flex
ancestors so `truncate` can finally take effect.
- Cap and ellipsize model / skill / tool-group badges via a small
`TruncatedBadge` (`block max-w-full truncate`).
- Reveal the full value on hover, but only when the text is actually
clipped (`TruncatedTooltip`, width + height detection), so names,
descriptions and labels stay readable without popping redundant
tooltips on short cards.
* fix(frontend): wrap unbreakable strings in agent card tooltips
A long token with no break opportunity (no spaces or hyphens) could still
overflow the tooltip horizontally. Add `break-words` next to the existing
`text-wrap` so such strings wrap instead of overflowing.
Addresses Copilot review feedback on tooltip wrapping robustness.
* fix(frontend): show agent card tooltips instantly
Drop the explicit `delayDuration` so card tooltips fall back to the
provider's default 0ms delay. Instant feedback is better UX for revealing
text that is already clipped, per maintainer review.
