* feat(models): add declarative reasoning capability contract (#5073)
Introduce an optional per-model `reasoning:` block beside the legacy
`supports_thinking` / `supports_reasoning_effort` booleans. It declares
thinking availability (unsupported | optional | required), the accepted
effort values with aliases, default, and serialization path, the payload
dialect, and the reasoning-history requirement. When present the booleans
are derived from it and contradictory profiles fail at config load.
`deerflow.models.reasoning` normalizes legacy and declared profiles into
one immutable contract and resolves every caller's generic request against
it. `create_chat_model` is the single enforcement point: required-thinking
models never receive a synthesized disable payload, unsupported effort
values never reach the provider, and the dialect synthesizes the on/off
payload when no template exists. Legacy profiles keep the historical path
byte-for-byte. The lead agent and subagent descriptor resolve the same
policy first so run metadata reports effective values.
`/api/models` and `DeerFlowClient` project the contract as `reasoning`;
the frontend derives mode clamping and effort choices from it through
`core/models/reasoning.ts`, and user preferences accept provider-specific
effort tokens. The setup wizard's Z.AI GLM-5.3-Flash profile migrates to
the contract, restoring its low/high/max effort control.
* docs(models): move the reasoning contract guidance into models/AGENTS.md
backend/AGENTS.md sits within 46 bytes of the 96 KiB effective-chain hard
limit for the middlewares, runtime, sandbox, and subagents guides, so the
new section pushed scripts/check_agent_guidance.py over it. The models
guide is the nearest file for the factory and the contract module, and
its chain has ample room.
* fix(models): address review on the reasoning contract
- vLLM dialect: the enable path now mirrors whichever chat_template_kwargs
switch the template declares, like the disable path already did, so a
template using the older `thinking` key no longer also grows
`enable_thinking`.
- Validate operator-supplied effort values at `effort.path` inside
`when_thinking_enabled`, `when_thinking_disabled`, and the `thinking`
shortcut against the contract, not only the profile-level value; they are
forwarded when the caller chooses nothing, so the "unknown values never
reach the provider" guarantee now holds for them too.
- Constrain `effort.path` to dotted identifiers and reject single-segment
paths that would replace a whole mapping (`extra_body`, `thinking`,
`model_kwargs`, `default_headers`, `default_query`).
- Z.AI GLM-5.3-Flash profile: `default: high` instead of `max`, because the
default also governs summarization, title generation, and subagent calls
that never choose an effort; `max` stays selectable. Documented in the
config example, the configuration manual, and the design note.
* fix(models): close reasoning contract review gaps
* fix(models): preserve native Ollama reasoning config
* fix(models): keep native reasoning strings and project reasoning into the descriptor
- `ModelConfig.reasoning` also accepts the level string ChatOllama takes
for gpt-oss style models (`low` / `medium` / `high`); the factory forwards
both the boolean and the string on the legacy path, so profiles that
passed `reasoning: high` through before the contract field existed keep
loading and keep sending it.
- The assembly descriptor no longer excludes `reasoning` from
`model_parameters`: the native ChatOllama value and a declared contract's
dialect/history/effort change the request payload, so they now move the
assembly fingerprint.
- e2e: the sidecar spec pinned the pre-contract body where a model without
effort control still received `reasoning_effort: minimal`; the preset is
now dropped for such models (the Gateway discarded it anyway), so the
assertion expects the key to be absent.

* feat(scheduler): add interval schedule type
Allow scheduled tasks to fire every N seconds from last dispatch, not
only wall-clock cron or a single run_at. Cadence is UTC now+N with no
missed-beat catch-up, bounded by min_once_delay_seconds and 30 days.
* fix(scheduler): let interval tasks create, edit, and keep next run
Create/edit now keep every_seconds. Unchanged interval spec no longer
resets next_run_at, including timezone-only PATCH.
* fix(scheduler): keep non-minute intervals on edit
Stop rounding every_seconds to whole minutes in the form. Values that
are not whole minutes or hours now use a seconds unit so edit/duplicate
round-trips the stored cadence instead of rewriting it and resetting
next_run_at. Document that min_once_delay_seconds is also the interval
floor.
* fix(scheduler): clamp interval seconds to the default 60s floor
The new seconds unit allowed 1–59, which the API rejects under the
default min_once_delay_seconds. Clamp the form to >= 60 and show the
floor next to the preview. Also mention interval in the scheduler
field_doc, matching config.example.yaml.
* fix(scheduler): do not clamp interval amount while typing
Keystroke clamp made 90 become 9 -> 60, then 600, and backspace could
not leave 60. Keep the raw field text and apply the 60s floor on blur
and emit only.
* test(scheduler): cover interval input editing
* fix(frontend): preserve saved interval cadence until edited
* style(tests): format scheduled task router tests

* test(threads): add red R3/R4 merge ordering regressions
* fix(threads): preserve trusted seq positions through content merge (R3/R4)
Extract the message ordering/identity logic into a pure
core/threads/message-order.ts module. Each normalized identity now tracks
latest visible content and trusted position separately: content replacement
no longer drops deerflow_seq/run_id/turn_duration (R3), and a seq-carrying
live message is placed by the ascending seq skeleton instead of the next
shared identity anchor (R4: 1,3,2,5 -> 1,2,3,5).
buildVisibleHistoryMessages converges repeated identities to the earliest
visible feed row (mirroring backend get_message_seqs), and the
summarization transient bridge plus rendered ledger share the same
position priority: trusted seq outranks anchor weaving, bridge refreshes
keep known seqs, and hidden control copies never contribute a visible
position.
* test(e2e): add long-thread ordering regression with compaction and pagination
Add tests/e2e/thread-ordering.spec.ts: a deterministic 68-row, 33-turn
fixture with two hidden compaction summaries, a paginated /messages/page
mock, and a live compaction during submit (real SSE frame shapes). Asserts
DOM group order at stage barriers, outline/scroll navigation across the
virtualized list, tool-card association, and order stability across reload.
Also close three mock gaps in mockLangGraphAPI (token-usage, mcp-tasks,
workspace-changes): unmocked they fell through to the absent gateway and
the 401 redirected thread pages to /login, breaking every thread-page spec
in a gateway-less Playwright environment.
* test(threads): address review on ordering regression coverage
- e2e: actually expand the collapsed web_search step and assert the
intermediate result payload (realistic JSON array fixture); assert the
new turn's DOM relative order via compareDocumentPosition instead of
racing viewport coordinates; add a Custom Agent route regression sharing
the same paginated fixture.
- Add a unit test for the hidden-control-only seq fallback path.
- Keep isNonEmptyString in hooks.ts (message-order.ts does not use it).
- Document the seq-first position authority contract in frontend/src/AGENTS.md.
* test(threads): type run_id fixtures via getMessageRunId accessor
* test(e2e): exercise the real collapsed-steps region for the tool payload check
The previous toolStep.click() was a no-op: as the last tool call, the
web_search step rendered unconditionally. Add a second tool call to the
turn-30 fixture so web_search falls into the collapsed moreSteps region,
assert the intermediate result payload is hidden while collapsed, then
click the "1 more step" button and assert it becomes visible.

* fix(frontend): default to Webpack over Turbopack in dev to avoid PostCSS worker leak on macOS
On macOS arm64, Turbopack + Next.js 16.2.11 + Tailwind CSS v4 causes an
unbounded spawn of PostCSS evaluator processes that consume high CPU and
memory and never return a response. Webpack is unaffected.
Change the no-override default in getDevBundler() from platform-dependent
Turbopack (all non-Windows) to Webpack. DEER_FLOW_DEV_BUNDLER=turbo
continues to work as an explicit opt-in for local diagnosis.
Fixes#5132
* docs(frontend): address webpack default review feedback
* docs(frontend): clarify webpack default rationale
* feat(frontend): render markdown artifacts in the new window
The artifacts panel's "open in new window" action handed the browser the
raw Gateway response. For markdown that is a `text/markdown` body the
browser can only show as source, so the new window was a text dump rather
than a reader.
Route markdown artifacts to a new `/artifacts/view` page that renders them
with the same components the panel uses (SafeStreamdown + the artifact
rehype chain + citation links/panel), including the truncated-preview
banner and its "load full file" action. Everything else keeps the raw
Gateway URL — notably HTML/SVG, which the Gateway deliberately serves as a
download so active content never executes in the application origin.
- `core/artifacts/viewer.ts` centralizes which stored artifacts are
markdown (`.skill` archives included, since they hold a SKILL.md), so
the panel and the viewer route cannot drift.
- `ArtifactFilePreview` and its siblings move out of
`artifact-file-detail.tsx` into `artifact-file-preview.tsx`; otherwise
the standalone route would pull the CodeMirror editor into its bundle.
- The window title comes from the route's `generateMetadata`, not
`document.title`, which the App Router overwrites after hydration.
- The viewer reads content through `useStandaloneArtifactContent`, which
shares `useArtifactContent`'s query key but not its `useThread`
dependency, since a detached window has no thread context.

* fix(frontend): keep the artifact target across re-authentication
Review found the standalone viewer unrecoverable from an expired session.
The window's target lives entirely in `?path=...&thread_id=...`, and both
auth paths dropped it:
- The layout guard redirected to `/login` with no `next` at all. A layout
cannot read `searchParams`, so the guard moves into the page, which can
— and rebuilds the full viewer address for `next`. The layout loses its
AuthProvider along the way: nothing under this route reads `useAuth`,
and the guard now makes a single `getServerSideUser` call per request.
- The shared fetch wrapper built `next` from `window.location.pathname`,
which silently truncated the query string. It now carries `search` too,
so any route holding state in the query survives a 401, not just this
one. `validateAuthNextPath` already accepts a query string.
`buildArtifactViewerURL` is split out of `resolveArtifactOpenURL`: the
guard needs the route itself, never the Gateway fallback that the latter
takes for non-markdown targets.
Tests: the login round trip (unit — the rebuilt URL survives
`validateAuthNextPath` and parses back to the same target), the fetch
wrapper preserving the query on 401 (unit), and the expired-session
window reaching `/login` with the artifact intact (E2E). The E2E asserts
on the popup's navigation *requests*, since `(auth)/layout` answers
`/login` with a server redirect under DEER_FLOW_AUTH_DISABLED and no
navigation commits.
`tests/unit/core/models/api.test.ts` stubbed `window.location` without
`search`; a real Location always has it.
Claude-Session: https://claude.ai/code/session_013AiCrC5SBc3HdFYNxsp1EC
* fix(frontend): keep public showcase artifacts out of the auth gate
Review found that the viewer's access check regressed `/showcase`. Those
pages render with `isMock`, their artifacts are served by the
unauthenticated demo route, and the raw artifact URL this window replaced
stayed public — so gating the window unconditionally bounced every
logged-out showcase visitor to /login for a document that is already
public.
`requiresAuthenticatedViewer` exempts a mock target only when
`resolveStaticDemoArtifact` would actually serve it. The allowlist is the
authority rather than the flag: `mock=true` is caller-supplied, so a
target the demo route answers with 404 — a non-allowlisted path, or a
thread that is not a demo thread — still needs a session.
Covered in `tests/e2e-auth/`, since the default E2E config disables auth
and cannot see this: a public showcase artifact renders without a
session, while a non-allowlisted path and a missing mock flag both land
on /login. Verified the positive case goes red without the exemption.

* Stabilize Windows frontend development startup
Next.js Turbopack can infer a user-level workspace root and hit an internal Rust task panic on Windows. Keep the frontend root explicit and select Webpack on Windows while preserving Turbopack elsewhere.
Constraint: The existing non-Windows development workflow should keep Turbopack.
Rejected: Disable Turbopack on every platform | unnecessary performance regression.
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Revisit the Windows Webpack fallback after the upstream Turbopack panic is resolved.
Tested: Prettier, ESLint, TypeScript, 139 frontend test files with 1060 tests, and Windows pnpm dev smoke test on port 3010.
Not-tested: Production build and browser E2E suite.
Related: #4957
* Make the frontend bundler fallback diagnosable
Keep the Windows Webpack fallback while allowing local diagnosis to select either supported Next.js bundler. Resolve the Turbopack root through the Node 20-compatible URL API so the explicit workspace boundary remains effective across the declared Next.js engine range.
Constraint: Windows defaults to Webpack because of the observed Turbopack panic, while non-Windows defaults to Turbopack.
Rejected: Accept arbitrary bundler values | Next.js only supports the two explicit flags and invalid values should fail early.
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Revisit the default Windows fallback when the upstream TaskGuard issue is resolved; the override is intentionally retained for diagnosis.
Tested: Frontend format, ESLint, TypeScript, 139-file/1062-test Rstest suite, target launcher tests, and next.config.js absolute-root load check.
Not-tested: Production build and browser E2E suite.

* feat(frontend): reopen the skill list after a skill is selected
Selecting a skill closed the composer's skill list for good: `/` no longer
reopened it, so a skill could not be looked up or swapped without deleting
the chip first.
The list now reopens from the editable text beside the chip, and picking an
entry swaps the chip rather than stacking a second activation, since the wire
format carries exactly one leading /skill. Builtin commands are withheld in
that state because they own the whole composer line, and Enter navigates the
list before submitting except while an IME is composing.
The trigger is unchanged: a slash still opens the list only at the start of
the input.
* fix(frontend): keep builtin names reserved in the reopened skill list
Withholding the builtin list from getMatchingSkillSuggestions in chip mode
also disabled the reserved-name filter it drives, so a custom skill named
after a builtin command became selectable there. Nothing rejects such a name
at install time, and submitting the resulting chip runs the command instead
of the skill.
Pass the builtin list as before and drop the builtin entries from the result
instead. The new regression covers both sides of the reservation, and the
reopen test now waits for the list before pressing Enter.
* fix(frontend): hide skills the slash parsers refuse from the picker
The composer picker reserved only the two builtin command names, while both
slash parsers refuse the seven names in the shared contract. A skill named
bootstrap, help, memory, models, new or status was therefore offered, could
be selected into a chip, and submitted — and then activated nothing, because
parse_slash_skill_reference drops the name on the way in. The turn reached
the model as literal text with no skill loaded and no error anywhere.
Reserve the contract names alongside the builtin ones, so the picker cannot
offer what the parsers will not honour.
* feat(artifacts): inline editing for text artifacts in the panel
Add a PUT /api/threads/{id}/artifacts/{path} endpoint that atomically
replaces an existing UTF-8 text file under /mnt/user-data/outputs after
verifying its SHA-256 revision. Active runs conflict (409); binary,
symlink, oversized, and non-output paths are rejected.
Frontend: edit/save/discard buttons, draft state with conflict detection,
CodeEditor onChange/onSave, loader SHA-256 from ETag, i18n, beforeunload guard.
Backend: PUT endpoint with thread reservation, atomic temp-file replacement,
sandbox sync for non-mounted providers, rollback on failure, ETag on GET.
Tests: 8 backend + 1 blocking-IO + 3 frontend test files.

* feat: show real-time context window usage in chat UI (#3125)
Adds a `context_usage` block to `GET /api/threads/{id}/token-usage`
(token count from the live checkpoint, the thread model's
`context_window`, and a percentage), introduces a new
`ModelConfig.context_window` distinct from the per-call `max_tokens`
output cap, and surfaces the percentage in the chat header — inside
`TokenUsageIndicator` when token-usage tracking is on, or as a
standalone badge when it's off so context capacity stays visible
independent of cost tracking.

* feat: per-category breakdown for context window usage
Replace the single-number context_usage payload with a Claude-Code-style
breakdown — messages, system prompt, skills, system/MCP tools (active +
deferred), custom agents, memory injection, autocompact buffer, and free
space — and surface it in the chat UI with a segmented progress bar and
per-row table.

* docs(config): document context_window across model examples
Add `context_window` to every example model in config.example.yaml so the
new chat-UI "% context used" indicator works out of the box for whichever
example a user adopts. Each value is the published default at the time of
writing; users are pointed at the official model spec to verify. Bumps
config_version to 11 so `make config-upgrade` flags outdated user configs.

* review: address Copilot bot comments on #3183
- token-usage-indicator: switch `{contextPercentage && (...)}` to an
explicit `!= null` check. (The string `"0"` is actually truthy in JS so
the original code wasn't buggy, but the explicit check is clearer.)
- context-usage-breakdown: drop the `useMemo` around segments/totals — the
computation is O(n) over a handful of rows and the previous memo deps
omitted `t.contextUsage.categories`, so the bar's tooltips/aria-labels
could stay in the old language after a locale switch.
- context_usage._split_tools: snapshot MCP names from
`get_cached_mcp_tools()` directly instead of re-reading
`extensions_config.json` after `get_available_tools()` already loaded
it. Removes redundant file I/O on every `/token-usage` poll.
(`get_available_tools()` still emits its own INFO logs — silencing
those is out of scope here.)

* fix(gateway): correct context-usage breakdown + add exact token counting
The context-usage indicator shipped two bugs that silently zeroed whole
breakdown rows (both caught by try/except, so the feature looked alive but
produced wrong numbers):
1. _count_system_prompt passed app_config= to get_deferred_tools_prompt_section,
which only accepts deferred_names -> TypeError swallowed -> system_prompt
row always 0, and used_tokens/percentage undercounted by the full prompt.
Also subtracted the deferred section twice (the rendered prompt already
excluded it). Fix: derive deferred names deterministically and pass them to
apply_prompt_template; drop the redundant subtraction.
2. _split_tools imported a non-existent get_deferred_registry -> ImportError
swallowed -> all four tool-category rows always 0. Fix: classify via the
public is_mcp_tool predicate + tool_search.enabled (mirrors
build_deferred_tool_setup); the MCP tag is set by get_available_tools.
Added token_usage.counting (approximate|exact). 'exact' routes text/schema/
message counting through the model tokenizer (tiktoken cl100k_base) via the
existing memory-module machinery (lazy load + cache + cooldown + CJK-aware
fallback), so CJK-heavy threads stop being undercounted by chars//4.
Regression + e2e tests added; 6621 backend tests pass.
* fix(gateway): harden context usage accounting
* fix(gateway): count promoted MCP tools as active in context usage
Promoted tools (deferred MCP tools the thread has fetched via tool_search)
have their full schema bound on every subsequent turn by
DeferredToolFilterMiddleware, so they consume context like any active tool.
The breakdown previously left them in the reserved *_deferred rows, under-
counting the thread's used_tokens.
Classification now treats a tool as deferred only when tool_search is enabled,
it is MCP-sourced, AND it has not been promoted. The promoted set is read from
the checkpoint's channel_values and scoped by catalog hash — matching the
runtime middleware, so a stale promotion from MCP-config drift cannot inflate
the active count.
The static system prompt still lists all deferred tool names (promotions only
affect schema binding, not the prompt), so _count_system_prompt's deferred
rendering is intentionally left unchanged.
8 new tests cover classification, catalog-hash scoping (match / drift /
compute-failure / malformed), and checkpoint extraction.

* fix(frontend): refresh active artifact content
* fix(frontend): remove 1Hz polling, keep only final refetch after run
Address review feedback: the 1Hz refetchInterval could poll
indefinitely when a write tool call is left unresolved (abort,
error, or missing ToolMessage). Removing the polling entirely
eliminates this risk while still satisfying the core requirement:
artifact content is refreshed once when the run settles, so edits
are visible without a manual reload.
- Remove refetchInterval / hasActiveWrite logic from hooks.ts
- Delete refresh.ts (hasActiveWriteForArtifact helper)
- Delete refresh.test.ts
* docs: align README and AGENTS.md with settle-time refetch behavior
A reasoning model's turn showed its thinking below its answer while
streaming, then flipped to thinking-above-answer once the turn settled.
One message is rendered by two components with opposite ordering rules:
while streaming, an AI message with content and reasoning but no tool
calls yet is deliberately held out of the terminal bubble (#4304) and
rendered by MessageGroup's chain-of-thought panel, which pinned the
trailing reasoning disclosure to the bottom; the settled bubble paints
its <Reasoning> disclosure above the content.
Render the trailing reasoning disclosure before the assistant text that
follows it, and emit a message's reasoning step before its content step
in convertToSteps -- the step list was content-first, so ordering by
step position alone could not fix it. Assistant text emitted before that
reasoning keeps its earlier position.
This also covers two cases the report does not mention: tool-using turns
reversed the same way, and expanding "N more steps" showed a message's
answer above its own thinking.
* fix(frontend): render one workspace-change card per run
The workspace-change card is resolved from (threadId, runId) alone, so
every AI message in a run fetches the identical summary. It was rendered
per AI message.
getMessageGroups() opens a separate terminal assistant group for every AI
message that has content and no tool calls, so a run ends in more than one
bubble whenever the model emits answer text mid-run that never gains a
tool call. Each bubble then painted a byte-identical "Edited N files"
card.
Fold the card onto a single position per run, matching how run duration
already anchors its own run-scoped display after the run's last visible
group. Anchoring keys on group index rather than message id because a
terminal assistant group holds exactly one message whose id may be absent.
Fixes#4555
* docs(frontend): explain the workspace-change anchor's group-type restriction
The helper narrows anchor candidates to terminal assistant groups while
getRunDurationDisplaysByGroupIndex accepts a run's last group of any type.
That asymmetry is load-bearing: run duration is emitted by MessageList
around every group, but the workspace-change card comes from
MessageListItem, which MessageList invokes only for human/assistant
groups. Anchoring a run that ends in an assistant:processing group would
pick a position that never renders and silently drop the card.
Record the rule in both places that could invite a future "unification":
the helper's docstring, and the frontend AGENTS.md paragraph that tells
maintainers where run-scoped displays belong.
The shared right panel is collapsible with collapsedSize="0%", so dragging
the divider past minSize makes the library collapse it to zero without
going through the state that owns the panel. The panel disappears while
that state still reads open, leaving the divider draggable but inert and
the panel's trigger needing two clicks to bring it back.
Mirror a zero-width resize back into the owning state so a drag-collapse
closes the panel the same way its trigger does, and keep recording
non-zero widths there as the size to reopen at.
* feat(frontend): allow chat replies during clarification
