* feat(kanban): orchestrator-driven auto-decomposition on triage
Closes the core gap in the kanban system: dropping a one-liner into Triage
now decomposes it into a graph of child tasks routed to specialist
profiles by description, matching teknium's original vision ("main
orchestrator splits/creates actual tasks, doles them out to each agent").
The build
---------
- hermes_cli/profiles.py: new `description` + `description_auto` fields
on ProfileInfo, persisted in <profile_dir>/profile.yaml. Helpers
read_profile_meta / write_profile_meta. `create_profile` accepts
optional description.
- hermes_cli/profile_describer.py: new module — auto-generate a 1-2
sentence description from a profile's skills + model + name via the
auxiliary LLM (`auxiliary.profile_describer`).
- hermes_cli/main.py: new `hermes profile create --description ...`
flag; new `hermes profile describe [name] [--text ... | --auto |
--all --auto]` subcommand.
- hermes_cli/kanban_db.py: new `decompose_triage_task` atomic helper —
creates N child tasks, links the root as a child of every leaf
(root waits for the whole graph), flips root `triage -> todo` with
orchestrator assignee, records an audit comment + `decomposed` event
in a single write_txn.
- hermes_cli/kanban_decompose.py: new module — calls the auxiliary LLM
(`auxiliary.kanban_decomposer`) with the profile roster + descriptions
to produce a JSON task graph, then invokes the DB helper. Rewrites
unknown assignees to the configured `kanban.default_assignee` (or
the active default profile) so a task NEVER lands with assignee=None.
Falls back to specify-style single-task promotion when the LLM
returns `fanout: false`.
- hermes_cli/kanban.py: new `hermes kanban decompose [task_id | --all]`
CLI verb.
- hermes_cli/config.py: new DEFAULT_CONFIG keys —
kanban.orchestrator_profile, kanban.default_assignee,
kanban.auto_decompose (default True), kanban.auto_decompose_per_tick
(default 3), auxiliary.kanban_decomposer, auxiliary.profile_describer.
- gateway/run.py: kanban dispatcher watcher now runs auto-decompose
before each `_tick_once`, capped by `auto_decompose_per_tick` so a
bulk-load of triage tasks doesn't burst-spend the aux LLM.
- plugins/kanban/dashboard/plugin_api.py: new endpoints —
GET /profiles (list roster + descriptions),
PATCH /profiles/<name> (set description, user-authored),
POST /profiles/<name>/describe-auto (LLM-generate),
POST /tasks/<id>/decompose (run decomposer),
GET/PUT /orchestration (orchestrator/default-assignee/auto-decompose
pickers, with resolved fallbacks echoed back).
- plugins/kanban/dashboard/dist/index.js: new OrchestrationPanel
collapsible — dropdowns for orchestrator profile and default
assignee, auto-decompose toggle, per-profile description editor with
Save and Auto-generate buttons. New ⚗ Decompose button next to
✨ Specify on triage-column task drawers.
Behavior
--------
- A task in Triage gets fanned out into a small DAG of child tasks.
Children with no internal parents flip to `ready` immediately
(parallel dispatch). Children with sibling parents wait. The root
stays alive as a parent of every child — when the whole graph
finishes, it promotes to `ready` and the orchestrator profile wakes
back up to judge completion (the "adds more tasks until done" part
of the original vision).
- `kanban.orchestrator_profile` unset -> falls back to the default
profile (whichever `hermes` launches with no -p flag).
- `kanban.default_assignee` unset -> same fallback. Tasks NEVER end
up unassigned.
- `kanban.auto_decompose=true` (default) runs the decomposer
automatically on dispatcher ticks; manual `hermes kanban decompose`
is always available.
Tests
-----
- tests/hermes_cli/test_kanban_decompose_db.py — 7 tests for the
atomic DB helper (status transitions, dep graph, audit trail,
validation errors).
- tests/hermes_cli/test_kanban_decompose.py — 6 tests for the
decomposer module (fanout, no-fanout fallback, unknown-assignee
rewrite, malformed-JSON resilience, no-aux-client path).
- tests/hermes_cli/test_profile_describer.py — 10 tests for
profile.yaml r/w + the LLM auto-describer (yaml corrupt tolerance,
user-vs-auto description protection, --overwrite, fallback parsing).
E2E
---
- CLI end-to-end: created profiles with descriptions, dropped a triage
task, mocked the aux LLM with a 3-task graph -> verified all three
children were created with the right assignees, the dependency
edges matched the LLM's graph, root flipped to todo gated by every
child, audit comment + `decomposed` event recorded.
- Dashboard end-to-end: started the dashboard against an isolated
HERMES_HOME, verified all four new endpoints via curl (profile
listing, PATCH for description, PUT for orchestration settings,
POST for decompose). Opened the UI in the browser, confirmed the
OrchestrationPanel renders with all three pickers + the per-profile
description editor, typed a description, clicked Save, verified
~/.hermes/profile.yaml was written. Clicked Decompose on the triage
card and confirmed the inline error message surfaced as designed
("no auxiliary client configured").
* feat(kanban): surface decompose mode (Auto/Manual) as a one-click pill
The auto/manual toggle already existed as kanban.auto_decompose (default
true), but it was buried inside the collapsed Orchestration settings
panel — users couldn't tell at a glance which mode they were in. This
hoists it to a pill at the top of the kanban page so the state is always
visible and one click flips it.
UX
- New "⚗ Decompose: AUTO|MANUAL" pill in the kanban header. Emerald
styling when Auto is on (the default), muted/gray when Manual.
- Pill is visible both in the collapsed AND expanded Orchestration
settings views so context is preserved when the user opens the panel.
- Tooltip explains both states + what clicking does.
- Renamed the in-panel "Auto-decompose on triage / Enabled" checkbox
to "Decompose mode / Auto (default) | Manual" for language parity
with the pill.
Behavior preserved
- Default remains Auto (kanban.auto_decompose=true).
- Manual mode restores pre-PR behavior: triage tasks stay in triage
until the user clicks ⚗ Decompose on each card (or runs
`hermes kanban decompose <id>`).
Implementation
- plugins/kanban/dashboard/dist/index.js: load /orchestration on mount
(not just on expand) so the collapsed pill reflects real state.
Render mode pill in both collapsed and expanded headers. Reuses the
existing PUT /api/plugins/kanban/orchestration endpoint — no new
backend, no new tests required.
E2E verified
- Pill renders as "⚗ Decompose: AUTO" on page load (default).
- One click flips to "⚗ Decompose: MANUAL" with muted styling.
- config.yaml on disk shows auto_decompose: false after the flip.
- Second click round-trips back to Auto; config.yaml flips to true.
* feat(kanban): rename mode pill to "Orchestration: Auto/Manual"
Per Teknium feedback — "Decompose" was too implementation-specific.
"Orchestration" is the user-facing concept (the whole pitch is the
orchestrator profile routing work), and the pill is the front door to it.
- Pill text: "Orchestration: Auto" / "Orchestration: Manual" (title case,
no ⚗ prefix, no SHOUTY-CAPS for the mode value)
- In-panel checkbox label: "Orchestration mode" (was "Decompose mode")
- Tooltips updated to match
- No behavior change
* docs(kanban): document decompose, profile descriptions, orchestration mode
Brings the docs site up to parity with the PR. English build verified
locally (npx docusaurus build --locale en) — clean, no new broken links
or anchors. Pre-existing broken-link warnings (rl-training, llms.txt,
step-by-step-checklist, fallback-model) untouched.
- website/docs/reference/cli-commands.md
+ `hermes kanban decompose` action row in the action table, with
pointer to the Auto vs Manual orchestration section.
- website/docs/reference/profile-commands.md
+ `--description "<text>"` flag on `hermes profile create`.
+ Full `hermes profile describe` section: read, --text, --auto,
--overwrite, --all flags with examples.
- website/docs/user-guide/features/kanban.md (the big one)
+ Triage column intro rewritten around the Auto-decompose default
behavior, with pointer to the new Auto vs Manual section.
+ Status action row updated to mention both ⚗ Decompose and
✨ Specify on triage cards.
+ New "Auto vs Manual orchestration" section explaining the two
modes, how to flip them (pill, config), how routing-by-description
works, the no-None-assignee guarantee, plus a config knob table
(auto_decompose, auto_decompose_per_tick, orchestrator_profile,
default_assignee) and the two new auxiliary slots
(kanban_decomposer, profile_describer).
+ REST surface table gains 6 new endpoint rows: /tasks/:id/decompose,
/profiles (GET), /profiles/:name (PATCH), /profiles/:name/describe-auto,
/orchestration (GET + PUT).
- website/docs/user-guide/features/kanban-tutorial.md
+ Triage column blurb updated for Auto by default + Manual via the
pill, with cross-link to the Auto vs Manual orchestration section.
- website/docs/user-guide/profiles.md
+ Blank-profile flow now mentions --description and points to the
kanban routing model for context.
- website/docs/user-guide/configuration.md
+ `kanban_decomposer` and `profile_describer` added to the
`hermes model -> Configure auxiliary models` menu listing.
Port of the run_agent.py changes from #27219 to current main: the
_build_api_kwargs body was extracted into agent/chat_completion_helpers.
build_api_kwargs, so wire the xAI tool-schema sanitization there
(provider in {'xai', 'xai-oauth'} or base_url=api.x.ai). Logs a warning
instead of silently swallowing exceptions, matching the contributor's
review-followup fix.
Co-authored-by: zccyman <zccyman@163.com>
xAI's /responses endpoint rejects pattern and format JSON Schema keywords
in tool schemas with HTTP 400 'Invalid arguments passed to the model'.
The existing strip_pattern_and_format() only walked OpenAI-format tools
({'function': {'parameters': ...}}), missing Responses-format shapes
({'name': ..., 'parameters': ...}) used by codex_responses API mode.
This shows up most often with MCP-derived tools that carry validation
keywords (e.g. domain pattern regex in firecrawl, format: date-time)
through to the wire.
Extends the walk to handle both shapes. Auto-strip wiring is applied
separately in chat_completion_helpers (post-refactor location).
Closes#27197
14 focused tests on the extracted helper
``_xai_oauth_exchange_code_for_tokens`` cover:
Core contract:
* ``code_verifier`` is on the wire (RFC 7636 §4.5).
* ``code_challenge`` + ``code_challenge_method=S256`` are echoed
(the #26990 defense-in-depth that makes xAI's token endpoint
stop rejecting valid exchanges).
* ``grant_type=authorization_code``, ``code``, ``redirect_uri``,
and ``client_id`` are all locked.
* Content-Type is ``application/x-www-form-urlencoded`` (xAI
rejects ``application/json`` on this endpoint).
* The supplied ``token_endpoint`` URL is used verbatim — no
hard-coded constant sneaks in via a future refactor.
* ``timeout_seconds`` is forwarded; floored at 20s.
Sanity guard:
* Empty ``code_verifier`` raises ``xai_pkce_verifier_missing``
with a link to #26990 — and NOTHING is sent. Leaking the auth
code to a server that can't redeem it is the wrong failure mode.
* Empty ``code_challenge`` omits only the defensive echo; the
standards-compliant ``code_verifier`` request still goes out so
RFC-compliant servers keep working.
Error surfacing:
* Non-200 responses include both ``HTTP <status>`` and the body
verbatim — disambiguates 400 (PKCE / bad request) from 403
(tier denied, see #26847).
* Transport errors are wrapped as ``AuthError`` with the
``xai_token_exchange_failed`` code, so the surrounding
``format_auth_error`` UI mapping still fires.
* Non-dict JSON payloads raise ``xai_token_exchange_invalid``.
* 200 happy path returns the parsed payload dict verbatim.
End-to-end wire-format guard:
* A real ``httpx.Client`` with a stub transport captures the bytes
on the wire and asserts every PKCE field round-trips through
``urlencode``. Catches a future refactor that swaps
``data=`` for ``json=`` (which xAI would silently reject).
xAI's OAuth implementation at ``auth.x.ai`` validates the PKCE
``code_challenge`` at the **token** endpoint, not just at the
authorize step. When Hermes sends the standards-compliant token
POST with ``code_verifier`` alone — exactly what RFC 7636 §4.5
prescribes — xAI rejects the exchange with ``code_challenge is
required`` and the user is stuck with no working OAuth login.
The fix:
* Extract the token POST into ``_xai_oauth_exchange_code_for_tokens``
so the wire format is unit-testable in isolation.
* Send the original ``code_challenge`` and ``code_challenge_method``
in the form body alongside ``code_verifier``. Strict RFC-compliant
servers ignore the extras at the token endpoint, and xAI's
permissive implementation accepts the exchange. This is the
standard "defensive echo" workaround used by every OAuth client
that targets a server with this quirk.
* Refuse to fire the POST when ``code_verifier`` is empty — leaking
the authorization code to a server that can't redeem it is worse
than failing locally with an actionable error. The new error
code is ``xai_pkce_verifier_missing`` and the message points at
this issue for context.
* Surface the HTTP status code prominently in the 4xx error message
(``xAI token exchange failed (HTTP 400). Response: …``) so users
and maintainers can tell a 400 (bad request / PKCE problem) from
a 403 (tier denied, see #26847) at a glance instead of parsing
the JSON body by eye.
Closes#26990
Addresses reviewer feedback: when resolve_runtime_provider returns a dict
without the 'provider' key, the result must be None regardless of
configured_provider. This guards against malformed runtime responses.
Test: test_runtime_missing_provider_key_returns_none
Named custom providers (e.g. crof.ai) resolve to provider='custom' at the
runtime level, causing subagents to lose their intended provider identity.
On retry/fallback, resolve_provider_client('custom', model=...) searches all
providers advertising that model and picks non-deterministically, routing to
Z.AI or Bailian instead of the configured target.
The fix preserves configured_provider when runtime['provider'] == 'custom',
restoring the original provider name so routing stays correct through retries.
Adds a named constant _RUNTIME_PROVIDER_CUSTOM instead of a magic string.
Adds three regression tests:
- test_named_custom_provider_preserves_provider_name: the #26954 case
- test_standard_provider_not_overwritten_by_configured_name: openrouter/nous
must still return their own identity, not the configured name
- test_custom_provider_with_empty_configured_provider_falls_back_to_runtime:
empty provider triggers the early-return None path as before
When the dashboard is reverse-proxied under a path prefix
(`X-Forwarded-Prefix: /dashboard`), the SPA already routes its
`/api/...` REST traffic through `HERMES_BASE_PATH` via
`web/src/lib/api.ts`. Three WebSocket URLs constructed elsewhere
were still hardcoded to root `/api/...` and so opened
`wss://host/api/...` instead of `wss://host/dashboard/api/...`,
forcing operators to forward selected root API/WS paths through the
reverse proxy as a workaround (see issue #25547).
Add `HERMES_BASE_PATH` between `host` and `/api/...` in the
three constructed WebSocket URLs:
- `web/src/pages/ChatPage.tsx` — PTY WebSocket
- `web/src/components/ChatSidebar.tsx` — events subscriber
- `web/src/lib/gatewayClient.ts` — JSON-RPC gateway WebSocket
When the dashboard is served at root, `HERMES_BASE_PATH === """
and the URLs are bit-for-bit identical to before. Under a prefix,
the WebSocket connections now go through the same proxy path the
REST calls already use.
Note: bundled dashboard plugins (kanban, hermes-achievements) embed
`"/api/plugins/..."` in their compiled `dist/index.js` and
remain out of scope here — those need source-side fixes per plugin.
Fixes#25547.
`_ws_client_is_allowed()` enforces a loopback-only client check on every
dashboard WebSocket upgrade (`/api/ws`, `/api/events`, `/api/pty`,
`/api/pub`):
def _ws_client_is_allowed(ws):
if _is_public_bind():
return True
client_host = ws.client.host if ws.client else ""
if not client_host:
return True
return client_host in _LOOPBACK_HOSTS
The intent is: when bound to 127.0.0.1, only accept WS upgrades from
loopback peers. Public bind (--insecure) trades that for token-only.
However, `uvicorn.run(app, host=host, port=port, log_level="warning")`
omits `proxy_headers`. In modern uvicorn (>= 0.20) `proxy_headers`
defaults to True and `forwarded_allow_ips` defaults to "127.0.0.1".
With those defaults, any reverse proxy connecting from loopback (nginx,
in-cluster proxy, Cloudflare Tunnel sidecar in HTTP mode, K8s
ingress-nginx) causes uvicorn to rewrite `ws.client.host` from the
request's `X-Forwarded-For` header. So the gate sees the original
client's IP (a public address) instead of the loopback peer, returns
False, and closes every browser WS with code=4403 (surfaces as HTTP
403 to the proxy).
Passing `proxy_headers=False` keeps the loopback gate's view of
`ws.client.host` at the immediate transport peer (the proxy on
127.0.0.1), which is exactly what the gate is designed to check.
The bug is invisible in dev (no proxy → no XFF → ws.client.host stays
loopback). It surfaces in proxied production: dashboard chat tab opens,
events feed banner shows "disconnected — tool calls may not appear",
all WS endpoints return 403. Reproduces with:
curl -i -H "Connection: Upgrade" -H "Upgrade: websocket" \
-H "Sec-WebSocket-Version: 13" -H "Sec-WebSocket-Key: ..." \
-H "X-Forwarded-For: 1.2.3.4" \
"http://127.0.0.1:9119/api/ws?token=\$TOKEN"
# Before: HTTP/1.1 403 Forbidden
# After: HTTP/1.1 101 Switching Protocols
Without the XFF header, both behave the same (101) — confirming the
single-variable trigger.
Discovered while diagnosing why the Hermes dashboard at
mandy.loadmagic.ai (behind nginx + Cloudflare Tunnel + CF Access)
refused all browser WS upgrades despite Access app config matching a
known-working sibling deployment (Simone, which doesn't have nginx in
the path).
The /restart command used a detached subprocess approach to restart
the gateway. In Docker, when the gateway process exits, tini (PID 1)
also exits, causing Docker to stop the container and kill the detached
helper before it can restart the gateway. This made /restart effectively
a /shutdown in containerized deployments.
Detect Docker (/.dockerenv) and Podman (/run/.containerenv) containers
and use the service restart path (exit code 75) instead, letting the
container restart policy handle the actual restart.
Note: requires restart policy that restarts on non-zero exit (e.g.
unless-stopped or on-failure).
Closes#25249 (and supersedes PR #25260) in spirit.
Two bugs in the streaming chat-completions path caused provider timeout
configuration to be silently ignored:
1. Hardcoded connect/pool timeout. The httpx.Timeout for streaming
calls used hardcoded connect=30.0 and pool=30.0 regardless of the
user's providers.<id>.request_timeout_seconds config. If the custom
provider (e.g. Ollama) was unreachable, the call always waited
exactly 30s before failing, ignoring any configured timeout.
Fix: use min(_base_timeout, 60.0) for connect and pool when a
provider timeout is configured, falling back to 30.0 otherwise.
The 60s cap addresses review feedback (TCP handshake shouldn't
wait the inference timeout — connect/pool cover the connection
layer, not model latency).
2. Streaming stale-stream detector ignored provider config. The
stale detector read only HERMES_STREAM_STALE_TIMEOUT (env default
180s). The providers.<id>.stale_timeout_seconds key (correctly
used in the non-streaming path) was never consulted.
Fix: check get_provider_stale_timeout(provider, model) first,
then fall back to the env var. Aligns the streaming path with
the non-streaming path's priority chain (config > env > default).
Salvage shape diverged from PR #25260: the function moved to
agent/chat_completion_helpers.py and the contributor's two commits
(initial fix + 60s-cap review follow-up) are squashed into one final
commit applied at the new location.

`hermes doctor` displayed OAuth status for Nous, Codex, Gemini, and MiniMax
but silently omitted xAI OAuth, even though `get_xai_oauth_auth_status()`
exists and the same information is already surfaced in `hermes status`.
Add xAI OAuth as a *separate* try/except block so an import failure cannot
silence the already-printed provider rows above it — consistent with the
per-provider isolation introduced in the doctor fallback fix.
Tests:
- 9 new tests in TestDoctorXaiOAuthStatus covering: logged-in ok, not-logged-in
warn, error line present/absent, import failure isolation, runtime exception
and None-return safety.
- 9 existing run_doctor helpers updated to mock get_xai_oauth_auth_status for
deterministic output.
hermes status listed Nous Portal, OpenAI Codex, Qwen OAuth, and MiniMax
OAuth in the Auth Providers section but omitted xAI OAuth entirely.
Users who authenticated via `hermes auth add xai-oauth` had no way to
verify their session state from the status output.
Add xAI OAuth display using the same field shape as OpenAI Codex:
auth_store (Auth file:), last_refresh (Refreshed:), and error when
not logged in. The import is isolated in its own try/except so an
import failure cannot affect the already-printed rows above it.
Tests cover:
- logged in: check mark, auth_store, last_refresh, error suppressed
- not logged in: login command hint, error shown, error absent = no line
- resilience: import failure, status function raises, returns None
- isolation: xAI import failure does not break Nous/MiniMax display
Shared try/except import block meant that if any one status function was
missing, all providers lost their OAuth fallback suppression. Split into
per-provider try/except so each branch is independently safe.
Add end-to-end test for xAI: bad XAI_API_KEY with healthy OAuth does not
surface a blocking issue in run_doctor output. Add tests for None return,
import failure isolation (xAI missing does not break Gemini), and move
test_returns_false_for_unknown_provider out of the xAI-specific class.
_has_healthy_oauth_fallback_for_apikey_provider() covers Gemini and
MiniMax (added by #26853) but omits xAI. The xAI provider profile
(plugins/model-providers/xai/__init__.py) has auth_type="api_key" and
env_vars=("XAI_API_KEY",), so it enters the generic API-key
connectivity loop. When XAI_API_KEY fails a 401 probe but xAI OAuth
is healthy, the failure is promoted to the blocking summary even though
xAI works fine via OAuth — the same false-positive #26853 fixed for
Gemini and MiniMax.
Fix: import get_xai_oauth_auth_status alongside the existing two
helpers and add the "xai" branch. get_xai_oauth_auth_status() already
exists in hermes_cli/auth.py and returns {"logged_in": True} when a
valid OAuth token is present.
Symmetric with the Gemini and MiniMax branches introduced in #26853.
No behavior change for providers without an OAuth path.
Copilot caught an important runtime parity gap on PR #27489: the fix
imported the npm `wrap-ansi` package directly, but Ink's `<Text
wrap="wrap">` uses a runtime-selecting shim
(`ui-tui/packages/hermes-ink/src/ink/wrapAnsi.ts`) that prefers
`Bun.wrapAnsi` when running under Bun and falls back to the npm package
elsewhere. So under Bun, Ink would render via `Bun.wrapAnsi` while
`cursorLayout` would compute breaks via the npm package — any
disagreement reintroduces the exact cursor-drift symptom the PR is
meant to eliminate.
Fix:
- Export `wrapAnsi` from `@hermes/ink` (`packages/hermes-ink/src/entry-exports.ts`
and `packages/hermes-ink/index.d.ts`) so the shim is the public surface.
- Switch `ui-tui/src/lib/inputMetrics.ts` from `import wrapAnsi from
'wrap-ansi'` to `import { wrapAnsi } from '@hermes/ink'`. Both
renderer (Ink) and cursor layout now traverse the same shim, so
they share the runtime-selected implementation by construction.
- Same swap in `textInputWrap.test.ts` and `cursorDriftRegression.test.ts`
— tests now assert parity through the shim, which means under Bun
they actually exercise Bun's implementation instead of asserting a
tautology against the npm package.
- Drop the direct `"wrap-ansi": "^9.0.0"` from `ui-tui/package.json`.
`@hermes/ink` (which IS a declared dep) pulls wrap-ansi in
transitively — that's not a phantom dep because the import path
goes through `@hermes/ink`'s public exports, not through a
hoisting accident.
Verified: 791/791 vitest tests pass. `@hermes/ink` rebuilt
(`dist/entry-exports.js` includes `wrapAnsi` export). TUI bundle
rebuilt clean.
Three small follow-ups from the Copilot review on #27489:
1. Declare `wrap-ansi` as a direct dependency of `ui-tui`. It was a
phantom dep that resolved via npm hoisting from `@hermes/ink`'s
transitive graph — fine on hoisted installs, but breaks under pnpm
or `npm install --no-install-strategy=hoisted` style isolated
installs. Now listed as `"wrap-ansi": "^9.0.0"` matching the
@hermes/ink version. Lockfile regenerated.
2. Implement the defensive resync the comment promised. Previously the
comment claimed the loop would "fall back to advancing by one to
stay in lockstep" on wrap-ansi desync, but the code unconditionally
advanced `originalIdx` with no actual check — so any future
wrap-ansi option change or styled-input caller could silently slide
`originalIdx` past the end of `value` and emit garbage line ranges.
Now actually compares `value[originalIdx] === ch`, re-syncs via
`indexOf` on mismatch, and bails out (returning whatever was built
so far) if the desync is unrecoverable. Production paths still hit
the equality fast-path on every char.
3. Drop the `visualLines` wrapper. It was a one-line indirection over
`visualLinesFromWrappedOutput`. Renamed the implementation to
`visualLines` and removed the wrapper — same name, no extra layer.
No behavior change beyond the defensive realign; all 791 vitest tests
still pass.
The composer's `cursorLayout` (in `ui-tui/src/lib/inputMetrics.ts`) used a
hand-rolled word-wrap algorithm to decide where `useDeclaredCursor`
should park the hardware cursor. But Ink's `<Text wrap="wrap">` renders
the same text via `wrap-ansi`. The two algorithms disagreed on common
real-world inputs — `"branch investigate"` at cols=20, `"hello world"`
at cols=8, exact-fill strings like `"abcdefgh"` at cols=8 — so the
hardware cursor parked several cells past where Ink actually rendered
the last character. Users saw a multi-cell blank gap between their
last-typed letter and the cursor block, especially on narrow terminals
(the Cursor IDE built-in terminal was the worst offender).
Three previous PRs (#26717, #25860, #22197) chased fast-echo
displayCursor/cursorDeclaration drift and in-band-vs-native cursor
heuristics. None of them touched the underlying wrap-algorithm
mismatch, which is why the bug kept resurfacing.
Fix: source cursorLayout's line breaks from wrap-ansi directly. Walk
its emitted string char-by-char, tracking original-string offsets, push
a VisualLine at each '\n'. Also drop the buggy `column >= w` overflow
rule in cursorLayout — that's what pushed exact-fill text onto a
phantom next row.
canFastBackspaceShape now detects the wrap boundary in BOTH coordinate
conventions (column === 0 OR column >= columns), since exact-fill now
reports as (0, columns) instead of the previous (1, 0). The physical
state is identical — the terminal auto-wraps at column N either way —
but the layout function reports the position more honestly.
Tests:
- ui-tui/src/__tests__/textInputWrap.test.ts: 3 tests that pinned the
BUGGY behavior were updated to assert wrap-ansi parity (the real
invariant). Added a typing-prefix invariant: cursorLayout must agree
with wrap-ansi at every character of a long input.
- ui-tui/src/__tests__/cursorDriftRegression.test.ts: new file. Walks
the user-reported bug message char-by-char at 7 widths and asserts
agreement with wrap-ansi at every prefix.
Verification:
- 791/791 vitest tests pass.
- 84/84 tui-gateway pytest tests pass via scripts/run_tests.sh.
- PTY repro (typing into a real `hermes --tui` PTY at cols=50/55/60):
cursor lands exactly 1 cell past the last typed char in every case
the bug previously drifted.
PR #25580 was authored before #2746 landed on main, so its plugin
versions of browser_use/browserbase/firecrawl ship without the
requests.RequestException → RuntimeError wrapping that 13c72fb4 added
to the legacy tools/browser_providers/ files for #2746. Cherry-picking
the PR + git rm'ing the legacy files (the migration's intent) would
silently revert that network-error fix.
Port the same try/except pattern into the three plugin create_session()
methods. Browser Use managed-mode keeps its raw-exception propagation
(idempotency-key retry semantics).

Addresses findings from two self-review passes pre-merge.
First pass (3-agent parallel review):
1. plugins/browser/browser_use/provider.py: drop the
``_ = managed_nous_tools_enabled`` dead-import-hider in
_get_config_or_none(). The import was actively misleading — the
helper IS used in _get_config() (separate method, separate import),
not here. The "keep static analysis happy" comment was wrong about
what the helper does in this scope.
2. agent/browser_provider.py: drop ``pragma: no cover`` from
is_configured() / provider_name() backward-compat aliases. They ARE
covered by ``TestLegacyAbcAliases`` — the pragma would have masked
future regressions.
3. tools/browser_tool.py: refactor _is_legacy_provider_registry_overridden()
to compare against a module-frozen _DEFAULT_PROVIDER_REGISTRY snapshot
instead of hardcoded set of 3 keys. Future maintainers adding a 4th
built-in provider now just extend _PROVIDER_REGISTRY; the override
detection adapts automatically. Previously the hardcoded
``set(...) != {"browserbase", "browser-use", "firecrawl"}`` would flip
True forever on any 4-key registry, silently routing every install
onto the legacy fixture path.
4. tools/browser_tool.py: when explicit ``browser.cloud_provider`` is set
but the registry has no matching plugin (typo, uninstalled plugin,
discovery failure), emit a WARNING with actionable text instead of
silently falling through to auto-detect. Legacy code surfaced a typed
credentials error via direct class instantiation; this log restores
the signal in the post-migration path.
5. agent/browser_registry.py: trim the triple-redundant _LEGACY_PREFERENCE
documentation. Module docstring + 13-line block-comment + 5-line
inline comment was repeating the same point. Kept the docstring and
trimmed the block-comment to 5 lines.
6. agent/browser_registry.py: upgrade is_available()-raised logging from
DEBUG to WARNING with exc_info=True. A provider's availability check
throwing is unusual enough that users debugging "no cloud provider"
need the traceback in logs.
7. tests/plugins/browser/check_parity_vs_main.py: drop dead top-level
imports (os, shutil, tempfile — only referenced inside the
SUBPROCESS_SCRIPT string literal that runs in a child process).
Second pass (architecture + claim-verification review):
8. tools/browser_tool.py: rewrite the inline comment in _get_cloud_provider
auto-detect branch. Prior text claimed it "routes through the plugin
registry's legacy preference walk so third-party plugins still get a
chance to be selected when they're explicitly configured" — false on
both counts. The branch uses module-level legacy class aliases
(BrowserUseProvider / BrowserbaseProvider) directly; third-party
plugins are intentionally reachable only via explicit
``browser.cloud_provider``. Corrected comment now matches behaviour
and cross-references _LEGACY_PREFERENCE for the firecrawl gate
rationale.
9. tools/browser_tool.py + tests/tools/test_managed_browserbase_and_modal.py:
drop the unused ``get_active_browser_provider as
_registry_get_active_browser_provider`` alias from the
``from agent.browser_registry import ...`` block. It was never
referenced; matching test-stub line in the agent.browser_registry
SimpleNamespace also dropped. ``get_provider`` is still imported (used
by the explicit-config dispatch path at line 535).
10. plugins/browser/firecrawl/provider.py: align emergency_cleanup()
with the early-guard pattern used in browserbase + browser_use
plugins. Previously firecrawl tried the DELETE and relied on
``_headers()`` raising ValueError to trip a "missing credentials"
warning; same final outcome but a different control flow that read
like a bug to a maintainer skimming the three modules. Now: if
is_available() is False, log+return early — identical shape to the
other two providers.
Verification: 54/54 unit tests + 13/13 parity scenarios still pass.
Two changes that go together:
1. tools/browser_tool.py — add _ensure_browser_plugins_loaded() and call
it from _get_cloud_provider() before consulting the registry. Normally
model_tools triggers discover_plugins() as an import side-effect, but
_get_cloud_provider() can be reached from contexts that haven't gone
through model_tools (standalone scripts, certain unit-test paths, the
new parity-sweep harness). Without the defensive call, the registry is
empty and _registry_get_browser_provider() returns None — silently
downgrading users to local mode when they explicitly configured a
cloud provider with no credentials yet. The behavior-parity sweep
below caught this as 4 scenario regressions (explicit-X-no-creds for
all 3 providers, and explicit-firecrawl-with-creds).
2. tests/plugins/browser/check_parity_vs_main.py — subprocess harness
that pins one Python invocation to origin/main and one to this PR's
worktree via sys.path.insert(), runs _get_cloud_provider() across a
13-scenario config matrix, and diffs the reduced shape tuple
(is_local, provider_name, is_available). Provider_name pulls from
provider.provider_name() which is the legacy CloudBrowserProvider
API and remains as a backward-compat alias on the new BrowserProvider
ABC, so the comparison is apples-to-apples regardless of class
identity.
Final result: PARITY OK across 13 scenarios. The four observable
config/credential matrices that exercise the dispatcher all match
origin/main bit-for-bit:
- no-config + no-env → local
- explicit local + any env → local
- explicit BB / BU / FC + no creds → provider returned with
is_available()==False (so dispatcher surfaces typed credentials
error; matches main exactly)
- explicit BB / BU / FC + creds → provider returned with
is_available()==True
- no-config + BU creds → Browser Use
- no-config + BB creds → Browserbase
- no-config + both → Browser Use (legacy walk first hit)
- no-config + FC only → local (firecrawl NOT in legacy walk)
- no-config + FC + BB → Browserbase (legacy walk skips firecrawl)
Per the dev skill's "behavior-parity for refactor PRs" rule — without
this subprocess sweep, 31/31 unit tests pass while the production code
path is silently broken for users who type `browser.cloud_provider:
browserbase` and run a single browser command without prior model_tools
import. Caught + fixed before push.
Mirrors tests/plugins/web/test_web_search_provider_plugins.py from PR #25182.
31 tests across 5 classes:
TestBundledPluginsRegister (8 tests)
- Three plugins register (browserbase, browser-use, firecrawl)
- Each plugin's name + display_name accessible
- get_setup_schema() returns picker-shaped dict with post_setup hook
- All three lifecycle methods (create_session, close_session,
emergency_cleanup) overridden on every plugin
TestIsAvailable (4 tests)
- browserbase needs BOTH BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID
- browserbase: api_key alone or project_id alone insufficient
- browser-use satisfied by BROWSER_USE_API_KEY
- firecrawl satisfied by FIRECRAWL_API_KEY
TestRegistryResolution (8 tests) — most valuable, locks down
pre-migration semantics:
- _resolve(None) with no creds returns None (local mode)
- _resolve('local') short-circuits to None
- _resolve('browserbase') returns provider even when unavailable
(so dispatcher surfaces typed credentials error)
- _resolve('firecrawl') same: explicit-config wins
- _resolve('unknown') falls through to auto-detect
- Legacy walk picks browser-use over browserbase
- browserbase-only configuration: browserbase wins
- **Regression**: firecrawl is NEVER auto-selected even when
single-eligible (preserves pre-migration gate; FIRECRAWL_API_KEY
shared with web firecrawl must not silently route to paid cloud
browser)
TestLegacyAbcAliases (6 tests)
- is_configured() delegates to is_available() for all three plugins
- provider_name() returns display_name for all three plugins
TestPickerIntegration (3 tests)
- _plugin_browser_providers() exposes all three plugins as rows
- Each row carries post_setup='agent_browser'
- browser_plugin_name marker matches browser_provider
All tests use real imports — no mocking of provider classes — so the
suite catches drift in the ABC, registry, picker injection, and plugin
glue layer simultaneously.
31/31 passing.
The four files in tools/browser_providers/ (base.py, browserbase.py,
browser_use.py, firecrawl.py) have been migrated into
plugins/browser/<vendor>/provider.py over the previous commits. No
in-tree code references them anymore — the legacy class names
(BrowserbaseProvider / BrowserUseProvider / FirecrawlProvider) are
re-exported from tools.browser_tool as aliases to the plugin classes,
so existing test patches keep working.
Updates tests/tools/test_managed_browserbase_and_modal.py:
- Adds _load_plugin_module() helper next to _load_tool_module().
- Reroutes five _load_tool_module('tools.browser_providers.X', ...)
calls to _load_plugin_module('plugins.browser.X.provider', ...).
- Renames BrowserbaseProvider/BrowserUseProvider -> the new plugin
class names (BrowserbaseBrowserProvider / BrowserUseBrowserProvider).
- Updates is_configured() -> is_available() on the one assertion that
cared about the rename (the others stay on is_configured() via the
BrowserProvider ABC's backward-compat alias).
Net diff: -630 / +39 lines (tests + dead-code deletion). Verified
23/23 tests in test_browser_cloud_*.py + test_managed_browserbase_and_modal.py
still pass.
Closes the file-tree mismatch portion of #25214. Remaining work:
new plugin-level test coverage under tests/plugins/browser/, behaviour
parity subprocess sweep vs origin/main, and full tests/tools/ regression
sweep before opening the PR.
