Subagents like `general-purpose -> implement layout export` that generate
text without calling tools would emit no `task_progress` events, making
them appear to have no progress. Fix by emitting progress on every
assistant message, not only when tool_use is present.
Also fix three related issues:
- Local async/background/foreground agent `output_file` now points to the
real agent transcript path instead of the `.output` symlink, avoiding
empty files when symlink creation fails on Windows.
- Agent async output now includes `taskId` alongside `agentId` so callers
don't confuse which field to pass to `TaskOutput`.
- `TaskOutput` missing-task error now explains the task may have been
evicted or belong to another session, and suggests reading `output_file`.
- `initTaskOutputAsSymlink` fallback writes a diagnostic message with the
transcript path instead of creating a misleading empty file.

* fix(reverse-engineering): declare missing tool-binary prereqs for 4 servers
Real-world repro on a fresh Win11 machine showed 4 servers fail in ways
the desktop one-click install couldn't surface, because their declared
`prerequisites[]` only covered the runner (uvx / java) and not the
underlying tool binary the runner needs at startup.
Smoke from a clean machine (uvx just installed, no other tools):
Before this PR
--------------
ghidra ⚠️ spawned, no JSON-RPC response in 5s (uv pkg slow first start)
radare2 ❌ prereq missing: radare2 ← already correct
gdb ❌ prereq missing: gdb ← already correct
lldb ❌ process exited (code=1) ← cause invisible
jadx ⚠️ spawned, no JSON-RPC response in 5s ← cause invisible
apktool ❌ process exited (code=1) ← cause invisible
frida ❌ process exited (code=1) ← cause invisible
After this PR (same machine, same tools)
----------------------------------------
ghidra ⚠️ spawned, no JSON-RPC response in 5s (unchanged — Ghidra is a GUI binary configured via GHIDRA_INSTALL_DIR, not a PATH command)
radare2 ❌ prereq missing: radare2
gdb ❌ prereq missing: gdb
lldb ❌ prereq missing: lldb ← now actionable
jadx ❌ prereq missing: jadx ← now actionable
apktool ❌ prereq missing: apktool ← now actionable
frida ❌ prereq missing: frida ← now actionable
→ All actionable failures now route through the existing
`PluginPrerequisitesModal` one-click install flow with per-platform
install commands, instead of letting the server crash mid-startup.
What this PR adds (servers.json)
- lldb prereq adds `lldb` → win32 LLVM (winget/scoop), macOS xcode-select / brew, linux apt/dnf
- jadx prereq adds `jadx` → win32 scoop, darwin brew, linux apt/snap
- apktool prereq adds `apktool` → win32 scoop, darwin brew, linux apt/snap
- frida prereq adds `frida` → uv tool / pipx / pip / brew (frida-tools is a Python pkg providing the `frida` CLI)
Plus a sibling `scripts/smoke-reverse-engineering-mcps.ts` that:
- reads the same plugin's `servers.json`
- probes each prereq via `where` / `command -v` (same primitive as
the desktop's `prerequisitesService`)
- if all prereqs pass, spawns the server and sends an LSP-framed
JSON-RPC `initialize` request, waits 5 s for the response
- prints a status matrix + auto-generated install commands per
platform (sourced from servers.json itself, not duplicated)
- flags schema gaps where a server name implies a tool that's NOT
in its prereq list (e.g. catches future regressions of this PR's
fix, plus the existing ghidra/Ghidra-binary case is correctly
excluded since Ghidra is GUI/env-var driven)
Why a smoke script in the repo
The existing `scripts/dev-mcp-test.ps1` is **only** the chrome-devtools
browser-MCP environment launcher (Vite proxy + H5 token) — not an
RE-plugin smoke. There was no equivalent reverse-engineering smoke,
so each maintainer had to reproduce by hand. With this script, future
"is the RE plugin healthy?" questions are one `bun run` away.
Plugin version: 0.4.3 → 0.4.4
Verification
- Manually ran `bun run scripts/smoke-reverse-engineering-mcps.ts`
on a fresh Win11 26200 with uv 0.11.21 just installed:
→ 6/7 cleanly classified as `prereq missing`, 1/7 (ghidra) gets
no response (expected — it needs `GHIDRA_INSTALL_DIR` to point
at a user-installed Ghidra binary; not a PATH command).
- The script's schema-gap heuristic correctly flags zero remaining
gaps after this PR.
Tested: live smoke on a real machine; before/after diff above.
Not-tested: macOS / Linux paths (only Win32 install map exercised).
The macOS/Linux paths are direct mirrors of the Win32 ones using the
relevant native package managers, sourced from each tool's official
install docs.
Confidence: high
Scope-risk: narrow
* fix(reverse-engineering): only ship 3 end-to-end verified MCP servers
Live smoke on a fresh Win11 26200 + an HTTP proxy showed that **4 of
the 7 MCP servers in this plugin cannot be made to start** under any
reachable upstream configuration:
| Server | Upstream tried | Failure mode |
|---------|------------------------------------------------------|---|
| radare2 | npm @radareorg/radare2-mcp; drvcvt fork; r2 official | npm 404; drvcvt has no `dist/`; official is C/Meson requiring compile |
| lldb | stass/lldb-mcp; stableversion/lldb_mcp | both upstream are single .py with no pyproject.toml |
| jadx | zinja-coder/jadx-mcp-server; mseep-jadx PyPI | upstream raises `ModuleNotFoundError: 'src'`; PyPI republish is 0-byte placeholder |
| apktool | zinja-coder/apktool-mcp-server; SecFathy/APktool-MCP | uv git fetch errors `Git operation failed`, persists past `uv cache clean`; SecFathy is unpackaged |
The previous commit on this PR (3fef2390) added prerequisites entries
for these 4 servers' tool binaries. That fix was correct in spirit but
moot in practice, because even after every prereq is satisfied the
servers still don't run — the failure isn't on the user's machine, it's
in the upstream packaging.
This commit takes the pragmatic step of removing the 4 broken servers
from `mcp/servers.json` so users no longer see four permanently-red
"Unavailable" cards in the desktop MCP page. The plugin now ships only
the **3 servers that have been live-tested end-to-end**:
| Server | Source | Verified state |
|--------|---------------------------------------|---|
| ghidra | uvx pyghidra-mcp | spawns; awaits user-set GHIDRA_INSTALL_DIR (by design) |
| gdb | npx mcp-gdb | spawns; needs `gdb` on PATH (prereq declared) |
| frida | uvx **frida-mcp** (PyPI v0.1.1) | ✅ initialize OK in 694 ms; serverInfo.name == "Frida" v1.27.2 |
Note frida changed source: was `uvx --from git+...kahlo-mcp@main kahlo-mcp`
(the upstream repo turned out to be a Node project in a `kahlo-mcp/`
subdir, not a Python package — so uvx couldn't install it). The PyPI
package `frida-mcp` is a clean, properly-packaged equivalent.
What this commit changes
- `plugins/reverse-engineering/mcp/servers.json` (-254/+0 net):
remove radare2 / lldb / jadx / apktool entries; rewrite frida entry
to use `uvx frida-mcp` (PyPI) instead of git+kahlo-mcp.
- `plugins/reverse-engineering/.claude-plugin/plugin.json`: 0.4.4 → 0.4.5.
- `plugins/reverse-engineering/README.md`:
· summary changes "ships seven" → "ships three" with an inline note
pointing at the new "Currently unbundled MCP servers" section
· external-tool prereq table trimmed to ghidra/gdb/frida
· new "Currently unbundled MCP servers" section explains exactly
which upstream broke and how, plus how a user can wire the
missing tools manually via shell + skills
· References list marks the 4 removed servers as `(deferred)` with
the specific upstream issue
- `scripts/smoke-reverse-engineering-mcps.ts`:
· transport fix — MCP stdio is NDJSON, not LSP-style Content-Length
framing. The earlier draft's framing was the reason `frida-mcp`
logged `Invalid JSON: EOF while parsing`; with NDJSON it now
cleanly returns the initialize result.
· schema-gap heuristic excludes `ghidra` (GUI binary, configured
via env var, never on PATH) and `frida` (frida-mcp PyPI bundles
its own Python frida client, no separate `frida` CLI needed).
Verification
Re-running smoke on a fresh checkout of this branch with proxy 127.0.0.1:7887:
```

Servers: 3
ghidra ⚠️ spawned but no JSON-RPC response in 5010 ms
gdb ❌ prereq missing: gdb

```
3/3 outcomes are correctly classified, 0 schema-gap warnings, and the
"Install commands for missing prereqs" section guides the user to
`scoop install gdb` / `pacman -S mingw-w64-x86_64-gdb` for the only
missing tool on this machine.
Tested: live smoke on a real Win11 box; before/after manifest count

Phase 4 of editor-lsp-foundation. The CLI agent's FileEditTool /
FileWriteTool / NotebookEditTool path was already vendored from upstream
and already drives the upstream LSP system. This PR bridges agent edits
into the desktop workbench (CodeMirror editor + workspace panel) without
touching the vendored tool code: the desktop chatStore observes the
agent's tool stream and refreshes/conflict-flags the panel itself.
Approach (option A in the spec discussion):
- chatStore: when a FILE_EDIT tool ('Edit'/'Write'/'NotebookEdit'/
'MultiEdit') completes, remember the toolUseId -> file_path mapping
in a per-session pending map. On the matching tool_result with
isError === false, consume the entry and call
workspacePanelStore.notifyAgentFileEdit(sessionId, absolutePath).
- workspacePanelStore.notifyAgentFileEdit: refreshes loadStatus when
the panel is open, and sets a 'source: agent' conflict on any open
editor buffer whose workspace-relative path matches the agent's
absolute path by suffix on a normalized segment boundary. Skips
buffers that already have a conflict so user-source banners aren't
clobbered. Uses sentinel hash 'agent-edit' because the chat tool
stream carries no content hash.
- Path matching normalizes backslashes -> forward slashes and trims
trailing slashes, then either equals or endsWith('/' + bufferPath)
to avoid foobar.ts matching bar.ts.
- Cleanup: clearPendingFileEdits added at the 3 existing pending-map
cleanup sites (disconnect, clear messages, new-session path).
Why no FileEditTool change:
The vendored upstream tool has no sessionId in ToolUseContext and
shouldn't import server WS modules from CLI process scope. The chat
stream already carries (sessionId, toolName, toolUseId, input, isError)
to the desktop and is the natural seam for desktop-side reactions —
same pattern the store already uses for TodoWrite -> useCLITaskStore
and Task* tools -> refreshTasks.
Tests:
- desktop/src/stores/workspacePanelStore.test.ts +6 (30/30 total)
Suffix match, Windows backslash, non-suffix substring rejection,
existing-conflict preservation, loadStatus when panel open, no
loadStatus when closed.
- desktop/src/stores/chatStore.test.ts +6 (112/112 total)
Edit/Write/NotebookEdit forwarding, isError gate, non-edit tool
isolation (Bash), single-fire on duplicate tool_result.
Verifier (independent agent) ran lint + both test suites + build +
bundle budget + 9 ad-hoc helper edge cases (Unicode paths, trailing
slash, identical absolute, deeper suffix mismatch). All PASS.
Bundle delta: +2.41 KB gz vs origin/main @ 95931d49 baseline
(97.59 KB headroom remaining).

* fix(providers): route 'Fetch Models' through server to bypass mixed-content / CORS
The "获取模型 / Fetch Models" button in the provider settings dialog used
to call upstream `/v1/models` directly from the renderer with `fetch()`.
That works for HTTPS providers whose endpoint sets permissive CORS
headers (e.g. api.openai.com, api.anthropic.com), but fails for any
plain-`http://` provider — most commonly self-hosted relay endpoints
like `http://47.116.22.0:3000`.
Two failure modes both surface as the same opaque "Failed to fetch":
1. Mixed-content block. The desktop renderer runs in a secure context
(Tauri at `tauri://localhost`, Electron with web security on), and
modern webviews refuse to fetch plain-HTTP URLs from a secure-context
page. The request never leaves the browser.
2. CORS-missing. Even when reachable, many self-hosted relays do not
return `Access-Control-Allow-Origin` for `/v1/models`, so the browser
blocks the response.
The "Test Connection" button never had this problem because it already
proxies through `POST /api/providers/{id}/test`, which runs on the local
server (Node, no webview restrictions). The fix routes "Fetch Models"
through the same server so it inherits the same isolation.
What this PR adds
Server side
- ApiError.badGateway(message) — new 502 helper for upstream failures.
- POST /api/providers/fetch-models with the new FetchModelsSchema (zod):
{ baseUrl: url, apiKey: non-empty, apiFormat: 'anthropic' | 'openai_chat'
| 'openai_responses' default 'anthropic' }.
- ProviderService.fetchUpstreamModels(input) — server-side GET against
`${baseUrl}/v1/models` (or `${baseUrl}/models` if baseUrl already ends
in `/v1`), reusing the existing network-proxy / timeout plumbing. Sets
Bearer for OpenAI-compatible formats, x-api-key + anthropic-version
for native Anthropic. Returns `{ status, data }` where `data` is the
upstream JSON verbatim. Non-2xx upstreams surface as ApiError.badGateway
with the upstream's `error.message` if the body has one. Network
failures and timeouts also map to badGateway with a clear message.
Desktop side
- providersApi.fetchModels(input) — new client wrapping the endpoint.
- handleFetchModels in Settings.tsx now calls providersApi.fetchModels
instead of fetching directly. The existing `extractModelEntries`
parser already accepts arbitrary upstream JSON (data / models / items
/ results arrays, plus { id | name | model } per entry), so no
parsing change was needed.
Tests
- 5 new ProviderService unit tests covering the wire shape:
· OpenAI format → Bearer header, GET /v1/models, no x-api-key
· Anthropic format → x-api-key + anthropic-version, no Authorization
· URL hygiene — strips trailing slashes, doesn't duplicate /v1
· Non-2xx upstream → ApiError 502 with `HTTP {status}: {message}`
· Network error → ApiError 502 with "Upstream fetch failed: ..."
Verification
- `bun test src/server/__tests__/providers.test.ts -t "fetchUpstreamModels"`
→ 5/5 pass.
- `bun run lint` (desktop): tsc --noEmit clean (after `bun install` to
pick up the @codemirror packages added by an earlier PR — orthogonal
to this change).
- All existing provider tests unchanged (no regression in test file).
Tested: server unit (5 cases covering wire shape, URL hygiene, error
paths); existing testProviderConfig tests still pass; desktop tsc clean.
Not-tested: live smoke against an actual self-hosted relay (no provider
fixture configured locally). The bug repro is well-understood: the
secure-context webview's mixed-content block is documented browser
behaviour and the fix removes the renderer-side fetch entirely.
Confidence: high
Scope-risk: narrow
* test(providers): add desktop-side fetchModels client test (clears change-policy block)
Locks the renderer→server contract: providersApi.fetchModels must POST to the local server with baseUrl/apiKey/apiFormat in the body, NOT fetch the upstream URL directly. The same-origin assertion guards against any future regression that reintroduces the mixed-content / CORS bug class.
Two cases:
- success path: upstream JSON forwarded verbatim, body shape locked
- error path: 502 from server surfaces upstream message in thrown error

* feat(solo): wire LSP error count into Tier-1 signals + cleanup suggestion
Phase 5 of editor-lsp-foundation (tasks 41-45):
- src/server/services/soloSuggestions.ts: SoloSignalsTier1 gains
lspErrorCount field + new ruleLspError. Rule fires on positive
integer counts only (defensive against undefined / 0 / non-integer
/ negative). Score 80 — high enough to outrank other 'cleanup'
candidates (todo-marker / sync-upstream / stash) via the existing
per-category dedup pass, and to outrank test-gap / ship / finish-wip /
release base scores so the user is told to clear type errors first
whenever the LSP reports any.
- src/server/services/soloSignalsService.ts: gatherSoloSignalsTier1 now
accepts an optional `getLspErrorCount` provider. Wrapped in
Promise.allSettled so an LSP failure / missing prereq silently
leaves lspErrorCount undefined — the rule then sits the round out
rather than nagging users about a setup problem they didn't ask
about. Existing callers don't pass the option, so no behavioral
drift on the current call sites; the manager will inject a real
provider when the LspManager singleton from Phase 3 is wired into
the Solo welcome-card pipeline.
- desktop/src/i18n/locales/{en,zh,zh-TW,jp,kr}.ts: 3 keys ×
5 locales = 15 entries for solo.suggest.lspError.{title,detail,
taskPrompt}. The other LSP-related i18n keys mentioned in the
spec (lsp.indicator.*, editor.unsupportedEncoding, editor.conflict.*,
editor.unsavedClose.*) are deferred to the component-integration PR
that swaps Phase 2/3's hardcoded English for translated labels —
shipping keys without callers would create dead code that drifts
out of sync before integration lands.
- src/server/services/soloSuggestions.test.ts: 6 new tests for
ruleLspError covering undefined / 0 / non-integer / negative gates,
positive-count emission, per-category dedup outranks
todo / sync-upstream when LSP errors exist.
- src/server/services/soloSuggestions.i18n.test.ts: fixtureWithEverySignal
now includes lspErrorCount, so the existing en.ts contract scan
automatically validates the 3 new keys.
Tested:
- bun test src/server/services/soloSuggestions.test.ts (44/44, +6 new)
- bun test src/server/services/soloSignalsService.test.ts
- bun test src/server/services/soloSuggestions.i18n.test.ts
- 61/61 across 3 Solo-related test files
- bun run lint (desktop tsc --noEmit clean — 5 locales × TranslationKey
mapped Record gates the additions)
Note: pre-existing e2e/business-flow failures (~44) on origin/main
remain untouched.
_Requirements: 14.1, 14.2, 14.3, 14.4, 14.5, 15.6_
* test(desktop): add i18n contract test for solo.suggest.lspError
Phase 5 follow-up: change-policy CI gate refused PR #27 because the
desktop locale changes shipped without a matching desktop test —
production code in `desktop/src/i18n/locales/*.ts` requires a
desktop-side test. The server-side i18n contract test
(soloSuggestions.i18n.test.ts) only validates en.ts, leaving the
4 other locales unchecked at the desktop boundary.
This test mirrors that contract on the desktop side: 5 locales × 3
keys = 15 presence checks, plus interpolation checks for {count} and
absence-of-params check for the static detail key. 18/18 passing.
The test imports each locale as a named export (the file's `export
const zh: Record<TranslationKey, string>` is repeated across all
five locale files, so `zh-TW.ts` needs `import { zh as zhTW }` to
disambiguate at the call site).
Tested:
- bun run test src/i18n/lspError.test.ts (18/18 pass)

* feat(server): LSP foundation infra — feature flag, JSON-RPC framer, process limits
Phase 3 base layer (tasks 18-20 of editor-lsp-foundation):
- src/server/services/lspFeatureFlag.ts: local opt-in switch.
spec called for `feature('LSP_FOUNDATION')` from `bun:bundle`, but
that table is build-time vendored from upstream Anthropic CLI and
fork code can't register new flag names there. So Phase 3 ships its
own check: dev (NODE_ENV !== 'production') is on by default; prod
is opt-in via `CLAUDE_CODE_LSP=1` env var. Pure function so unit
tests can stub `process.env` directly. 5/5 tests pass.
- src/server/services/lspJsonRpc.ts: minimal Content-Length-framed
JSON-RPC. encodeLspFrame(payload) emits the wire bytes;
LspFrameDecoder accepts arbitrary stream chunks (LSP servers split
frames mid-header / mid-body / multiple-per-chunk) and yields
complete frames per push(). Throws LspFrameDecodeError on missing
or non-numeric Content-Length. ~110 lines, no vscode-jsonrpc
dependency. 10/10 tests pass.
- src/server/services/lspProcessLimits.ts: poll-fallback strategy
(5 s sample interval, terminate after 2 consecutive overages).
spec also lists posix-rlimit and windows-job-object — those need
native bindings or N-API plugins we don't carry yet, so this PR
ships poll-fallback only and exposes a stable LspProcessLimits
interface so a future PR can plug in native strategies without
touching call sites. Sampler is abstract (manager passes a real
ps/Get-Process wrapper in production; tests pass a synthetic
array). 5/5 tests pass.
Tested:
- bun test src/server/services/lspFeatureFlag.test.ts (5/5)
- bun test src/server/services/lspJsonRpc.test.ts (10/10)
- bun test src/server/services/lspProcessLimits.test.ts (5/5)

lazy spawn via injected LspClientFactory; sha-clean state machine
(starting -> ready -> unavailable with 5 reasons). mapLspSeverity
maps LSP wire severity 1-4 -> error/warning/info/hint, anything
else -> error. makeDiagnosticComparator orders by severity ->

caps at top-20 entries / 5 distinct files. Idle eviction
(default 600 s) + restart cap (2 attempts in 60 s rolling window

* feat(solo): wire Solo Pipeline mode end-to-end (toggle + WS + handler + prompt)
Lights up the Solo Pipeline foundation that PR #16 / #17 staged. The
prompt text, suggestion engine, and Tier-1 signals are already on main;
this PR plugs them into the runtime so a user toggle actually flips the
CLI subprocess into Solo's 5-stage workflow.
What this PR adds (one PR, 4 layers, mirror of coordinator mode):
1. WS protocol — `set_pipeline_mode { flavor: 'solo' | 'normal' }`
- src/server/ws/events.ts: ClientMessage variant
- desktop/src/types/chat.ts: matching desktop variant
2. Server handler — `handleSetPipelineMode`
- src/server/ws/handler.ts: new in-memory `soloPipelineModeSessions`
Set, switch case in the message dispatcher, and a sibling of
`handleSetCoordinatorMode` that defers restart until the active
turn completes (same enqueueRuntimeTransition geometry).
- Mutual exclusion enforced server-side: enabling Solo clears
coordinator for the same session and vice versa, so the CLI
subprocess never sees both `--append-system-prompt` addenda.
- `RuntimeSettings.soloPipelineMode` threaded through all three
getRuntimeSettings return paths.
- Session cleanup deletes from both sets.
3. CLI args — `getSoloPipelineSystemPrompt()` injection
- src/server/services/conversationService.ts: when
`options.soloPipelineMode === true`, append the Solo prompt via
`--append-system-prompt`, lazy-required from the existing
`src/coordinator/soloPipelinePrompt.ts` (zero-cost when the flag
is off, no module-load on default builds).
- src/utils/systemPrompt.ts: parallel env-driven branch
(CLAUDE_CODE_SOLO_PIPELINE_MODE) for users launching the CLI by
hand, checked BEFORE coordinator's branch so Solo wins if both
env vars are somehow set.
4. Desktop UI + state — toggle in the `+` menu
- desktop/src/stores/sessionRuntimeStore.ts: new
`soloPipelineModes` map with localStorage persistence under
`cc-haha-session-solo-pipeline`, mirroring `coordinatorModes`.
`setSoloPipelineMode`, `clearSelection`, `moveSelection` updated
to keep the new map in lockstep with siblings.
- desktop/src/stores/chatStore.ts: `setSessionSoloPipelineMode`
action with mutual-exclusion logic — flipping Solo on clears
the coordinator flag (locally + over the wire); the coordinator
setter has the symmetric branch. Connect-time replay also now
re-emits `set_pipeline_mode` on reconnect when persisted.
- desktop/src/components/chat/ChatInput.tsx: parallel button to
the coordinator `+`-menu entry, lucide `linear_scale` icon,
primary-color check when active.
- i18n: `chat.soloPipelineMode` key added in en / zh / zh-TW /
jp / kr — all 5 locales required by the i18n contract.
Tests added
- src/server/__tests__/conversations.test.ts: getRuntimeArgs
appends Solo prompt under soloPipelineMode=true, omits it when off,
and emits two distinct `--append-system-prompt` slots (one per
mode) if both flags are passed (defensive — the WS handler enforces
exclusion, but getRuntimeArgs must still produce a deterministic
shape).
- desktop/src/stores/chatStore.test.ts: persist-without-live-session,
push-when-live, and BOTH directions of mutual exclusion (Solo
enables → coordinator clears, and vice versa) — verified to flip
both the local store and the wire payload in lockstep.
Verification
- `bun test src/coordinator/soloPipelinePrompt.test.ts` — 11/11
(pre-existing, unchanged: confirms the prompt text contract held).
- `bun test src/server/__tests__/conversations.test.ts -t "Solo"` —
3/3 new tests pass.
- `bun test src/server/services/soloSuggestions.i18n.test.ts` —
i18n contract still passes after adding the new key.
- `bun run lint` (desktop): tsc --noEmit clean, exit 0.
- `bun run test stores/chatStore.test.ts -t "Solo|coordinator"` — 4/4.
- `bun run test stores/sessionRuntimeStore.test.ts` — 6/6
(pre-existing, confirms backward compatibility of the runtime store
with the new soloPipelineModes field).
Constraint: must coexist with the parallel coordinator-mode work (B1 #15,
B2 #18, worker-continue #21, research-fork #22) already on main. Solo
shares the COORDINATOR_MODE feature flag with coordinator (gating both
in the same product wave) and uses the same restart geometry.
Confidence: high
Scope-risk: narrow
Tested: server unit (getRuntimeArgs Solo branch + mutual-exclusion arg
shape); desktop store unit (Solo persistence + bi-directional exclusion);
i18n contract; full desktop tsc.
Not-tested: live agent-browser smoke (no provider model wired in this
PR); next session resume of a Solo session (in-memory only per v1, same
as coordinator mode).
* feat(solo): always-visible status chip in chat header for Solo / coordinator mode
Closes the steering contract that says "must be explicit about current
mode" — until now, the toggle in ChatInput's `+` menu was the only
surface that showed mode state, and that menu is closed by default.
A user who enabled Solo and then minimized the menu had no way to
tell from the chat view whether they were still in Solo mode.
This adds a persistent chip in the chat header session-meta strip
(next to the existing `↗ Continued` hand-off chip), one chip per active
mode. The chips:
- Render only when the corresponding mode is on for the active session
(mutually exclusive at the action layer, but the rendering is
defensive — both could theoretically appear and that is harmless).
- Use lucide material symbols `hub` (orchestration) and `linear_scale`
(Solo) at 12px to match the chip-strip type scale.
- Carry tooltips explaining what the mode does and where to toggle it.
- Use the same primary-color treatment as the hand-off chip so the
whole strip reads as one band of "session-level facts about this
conversation".
- Have `data-testid` selectors (`session-coordinator-chip`,
`session-solo-chip`) for downstream test access.
i18n: 4 new keys × 5 locales (en/zh/zh-TW/jp/kr).
Verification: `bun run lint` clean (tsc --noEmit), no new diagnostics.
The runtime store reads were already wired in the previous commit on
this branch (sessionRuntimeStore.soloPipelineModes), so the chip is a
pure rendering layer with no behavior change.
Tested: tsc clean; existing handoff-chip pattern reused (proven
locally rendered already).
Not-tested: per-locale visual snapshot (no snapshot suite for this
header). Manual smoke recommended in the merged build.
Confidence: high
Scope-risk: narrow
* revert(solo): drop systemPrompt env-driven branch to clear CLI-core change-policy block
Removes the CLAUDE_CODE_SOLO_PIPELINE_MODE branch from src/utils/systemPrompt.ts (CLI core file). The desktop Solo wireup does NOT depend on this branch — it injects the Solo prompt via --append-system-prompt through conversationService.getRuntimeArgs. The reverted branch was a defensive addition for users who launch the CLI manually with the env var set; that path can be re-added in a follow-up PR with the allow-cli-core-change label and a co-located test file.
Manual CLI users wanting Solo can pass --append-system-prompt themselves until the follow-up lands. Desktop toggle path remains fully functional.
Confidence: high
Scope-risk: narrow (single file, single block)

* feat(desktop): add CodeMirror deps + bundle budget + encoding utils
Phase 2 foundation pieces (tasks 6-7 of editor-lsp-foundation):
- Add 9 @codemirror/* dependencies (state, view, commands, search, language,
autocomplete, lang-{javascript,json,markdown}). Tree-shaking keeps the
current bundle delta at +0.00 KB until WorkspaceEditor.tsx imports them
in task 8.
- Add scripts/check-bundle-budget.ts + bun script "check:bundle-budget".
Asserts dist/assets/*.js gzipped total <= baseline + 100 KB. Baseline
captured at origin/main @ 95931d49 (post-R5, pre-CodeMirror) = 3299.76 KB.
- Add encodingDetect.ts: detectEncoding(bytes) -> 'utf-8' | 'utf-8-bom' |
'unsupported' (uses TextDecoder fatal:true to map invalid UTF-8 to
unsupported); detectLineEnding(text) -> 'LF' | 'CRLF' | 'CR' (dominant
style with LF as fallback for empty/single-line buffers).
Tested:
- bun run test src/components/workspace/encodingDetect.test.ts -- --run (18/18 pass)
- bun run scripts/check-bundle-budget.ts (OK, +0.00 KB delta)
_Requirements: 1.3, 1.6, 1.7, 1.8_
* feat(server,desktop): workspace file save endpoint + buffer/conflict store
Phase 2 backend pieces (tasks 9-12 of editor-lsp-foundation):
Server:
- src/server/events/workspaceFileSaved.ts: shared emitter
emitWorkspaceFileSaved() so both write paths (user now, agent in PR-4)
funnel through one well-typed WS message shape.
- src/server/services/workspaceFileService.ts: WriteWorkspaceFileSchema
(Zod), atomic write (temp file + fsync + rename, Windows EBUSY/EPERM
retry 3x50ms), realpath-based symlink containment, BOM/CRLF/CR
round-trip, sha256 stale-base check (409 on hash mismatch), structured
400/404/409/500 error bodies, post-write workspace.file.saved emit.
- src/server/api/sessions.ts: POST /api/sessions/:id/workspace/file
routes through new handleSessionWorkspacePost; GET path unchanged.
- src/server/services/workspaceFileService.test.ts: 17 tests covering
200 / 400 (bad request, path-escape, parent-missing, absolute-path) /
404 session-missing / 409 stale-base / BOM round-trip / CRLF round-trip /
CR round-trip / temp-file-not-leaked / 10 MiB content cap. Includes
symlink-escape coverage on POSIX (skipped on Windows where symlink
creation needs elevation).
Desktop store:
- desktop/src/stores/workspacePanelStore.ts: bufferStateByTabId record,
WorkspaceBufferState/Conflict types, initBuffer / setBufferState /
applyExternalSave / acknowledgeConflict / clearBuffer actions.
applyExternalSave is the WS-driven entry point — clean buffers rebase
silently when content is supplied; dirty buffers raise a conflict
banner. acknowledgeConflict('reload') resets to base, 'keepMine' /
'openConflict' just dismiss the banner. closePreviewTabs and
clearSession now drop matching buffer state to prevent leaks.
Tested:
- bun test src/server/services/workspaceFileService.test.ts (17/17 pass)
- bun run lint (server tsc clean)
- bun run test src/stores/workspacePanelStore.test.ts (24/24 pass — store
extension is purely additive, R5 tests still green)
Note: pre-existing e2e/business-flow failures in src/server/__tests__/e2e
remain untouched by this change (44 fails on baseline, no new fails
introduced).
_Requirements: 1.5, 2.1-2.9, 3.1-3.3_
* feat(desktop): WorkspaceEditor + ConflictBanner + UnsavedChangesModal
Phase 2 UI pieces (tasks 8, 13, 14, 15 of editor-lsp-foundation):
- desktop/src/components/workspace/WorkspaceEditor.tsx: CodeMirror 6
editor wrapping the workspace panel buffer state. Hooks
EditorView.updateListener -> setBufferState for live dirty tracking,
picks language by extension (ts/tsx/js/jsx/json/md), wires Save to
sessionsApi.saveWorkspaceFile (R2 atomic write endpoint), refreshes
base hash on success, falls back to a read-only message when
detectEncoding returns 'unsupported'. External rebases (e.g. clean
buffer applyExternalSave) are pushed back into the EditorView via
dispatch.
- desktop/src/components/workspace/ConflictBanner.tsx: clean buffer ->
single Reload button; dirty buffer -> three buttons (Reload (discard),
Keep mine, Open conflict view). Renders workspace-relative path,
hash first 8 hex, relative timestamp refreshing every 60 s.
- desktop/src/components/workspace/UnsavedChangesModal.tsx: Discard /
Save / Cancel modal. Cancel is the default focus, Esc triggers it.
While saving, all three buttons disable and the host calls onSave
which only resolves close on success. 30 s in-prompt timeout fires
onTimeout (host owns the toast).
- desktop/src/components/workspace/WorkspaceEditor.test.tsx: 8 RTL
tests covering buffer init / encoding detection / unsupported
fallback / dirty marker / unsaved-changes modal flows / conflict
banner clean-vs-dirty layouts.
- desktop/src/api/sessions.ts: SaveWorkspaceFileInput +
SaveWorkspaceFileResult types and sessionsApi.saveWorkspaceFile
POST helper.
Bundle delta: +0.28 KB gz (CodeMirror 6 + 3 lang packs imported but
WorkspaceEditor is not yet wired into WorkspacePanel — that integration
ships in a follow-up PR alongside Phase 3 LSP work, keeping this PR
focused on the foundation).
Tested:
- bun run lint (tsc --noEmit clean)
- bun run test (workspacePanelStore 24/24, encodingDetect 18/18,
WorkspaceEditor 8/8, WorkspacePanel 27/27 — 77/77 across 4 files)
- bun run check:bundle-budget (delta +0.28 KB gz, 99.72 KB headroom)
- bun run build (clean, 1.20s)
_Requirements: 1.1-1.8, 3.2-3.5, 4.1-4.6_

R5 changes the workspace panel's default activeView from 'changed' to
'all' and removes the loadStatus auto-switching logic. Users now see
the all-files tree on first open, regardless of whether the session
has changed files. Explicit setActiveView still wins and survives
subsequent loadStatus calls via hasUserSelectedView.
The downstream WorkspacePanel component tests that asserted the old
"auto-switch to changed view" behavior are updated:
- 4 tests now explicitly setActiveView('changed') when they need to
exercise the changed-files list.
- 2 tests are rewritten/renamed (R5 prefix) to assert the new
"default to all, never auto-flip" contract instead of the old
switch-back behavior.
Tested:
- bun run lint (tsc --noEmit clean)
- bun run test workspacePanelStore.test.ts (24/24 passed)
- bun run test WorkspacePanel.test.tsx (27/27 passed)
- bun run build (clean, 1.21s, no bundle impact)
Note: 3 pre-existing failures in electron/services/{sidecarManager,terminal}.test.ts
exist on origin/main baseline and are unrelated to this change.

Resolves the only path that could plausibly cut coordinator-mode token
cost without changing architecture. Coordinator mode normally rejects
implicit forks (the orchestrator is supposed to delegate to typed
workers); this opt-in carves out a narrow window for cache-sharing
research fan-out only.
Why
===
Coordinator-mode parallel research dispatches several workers of the
same type. Each worker prefills its own system prompt + full tool
schema, easily 10-30k tokens × N workers. Fork's byte-identical API
prefix bypasses that entirely — the parent's prompt cache is fully
reused, marginal cost is just the directive bytes. On a 3-worker
research fan-out we expect ~10x prefill savings for the research
phase.
Out of scope: implementation/verification spawns still go through
typed workers (independent context, independent cache). This PR is
about research only.
What's in this PR
=================
- forkSubagent.ts
- New helper: isCoordinatorResearchForkEnabled() — gated on
feature('FORK_SUBAGENT') + isCoordinatorMode() + non-interactive
+ CLAUDE_CODE_COORDINATOR_RESEARCH_FORK=1.
- New constant: COORDINATOR_RESEARCH_FORK_SUBAGENT_TYPE = 'fork'
(single source of truth for what callers spell as subagent_type).
- New ForkMode union: 'normal' | 'coordinator-research'.
- buildForkedMessages / buildChildMessage now take an optional mode
parameter (default 'normal'). 'coordinator-research' adds rule 11
to the boilerplate: "RESEARCH FORK: do not modify files; report
findings instead". The first 10 rules are byte-identical to the
normal mode (cache-friendly), and the framing tag at the top is
unchanged so isInForkChild's recursive-fork guard fires for both
modes.
- AgentTool.tsx
- Adds a coord-research-fork branch in the agent-resolution code:
`subagent_type === 'fork'` + isCoordinatorResearchForkEnabled() →
routes through the same fork path as an omitted subagent_type.
- The omitted-subagent_type path in coordinator mode is unchanged
(still requires explicit type, with the existing helpful error).
- Computed forkMode threads through to buildForkedMessages.
- invocationLimiter.ts
- 'fork' default cap = 10 (between verification's 5 and the 8
fallback). Generous for legitimate parallel research, tight enough
that pathological loops show up before the budget runs out.
- forkSubagent.test.ts (new, 11 cases)
- Env-flag gating across all combinations.
- Boilerplate rule-11 injection in research mode + byte-identical
first 10 rules across modes (cache contract).
- Recursive-fork guard fires for both mode variants.
- Subagent type constant matches the literal "fork".
- invocationLimiter.test.ts
- One new case: default cap for 'fork' is 10.
- scripts/dev-coordinator-e2e.ps1
- Adds 8th e2e step: type constant, boilerplate variants, recursion
guard cross-mode, env-flag gate.
Why opt-in (and double-gated)
=============================
- Lazy-delegation lint and specialist redirect are blacklists: specific
anti-patterns, near-zero false positives, safe to default on.
- Coordinator research fork is a positive-space affordance: "the
coordinator MAY use a fork for research." Defaulting it on would
encourage forks for spawns that legitimately want a clean context
(e.g. adversarial verification), which conflicts with coordinator's
independent-worker philosophy.
- Two gates needed: feature('FORK_SUBAGENT') is the bundle-time
feature flag (we share its plumbing), CLAUDE_CODE_COORDINATOR_RESEARCH_FORK=1
is the user-level opt-in. Both must be on.
Risks considered
================
- Boilerplate divergence between modes would defeat the parent prompt
cache. Mitigated: research-mode boilerplate IS the normal-mode
boilerplate plus rule 11 at the end; first 10 rules are byte-identical
(covered by a test asserting that property explicitly).
- Recursive-fork guard could miss the new boilerplate. Mitigated: the
framing tag at the top is unchanged across modes (covered by tests).
- Model abuses 'fork' for non-research spawns. Mitigated: rule 11 in
the boilerplate forbids file modifications + invocationLimiter cap
10 contains pathological loops + opt-in flag means nothing changes
for users who don't turn it on.

Tested: bun test src/tools/AgentTool/forkSubagent.test.ts (11/11); all coordinator unit tests (144/144); scripts/dev-coordinator-e2e.ps1 step 8 GREEN
Not-tested: live coordinator session with the flag on producing actual cache savings (telemetry-only follow-up; the flag is gated and the boilerplate contract is enforced by test)
Confidence: high
Scope-risk: narrow
Constraint: must NOT change buildChildMessage's first 10 rules (cache identity); must NOT change the boilerplate framing tag (recursion guard); must NOT widen the gate to non-coordinator paths (fork stays mutex with normal coordinator delegation by default)
Rejected: defaulting the gate on (positive-space affordance, false-positive cost too high); adding `fork_research` as a new AgentTool input parameter (schema change rejected on B2 by the same logic — too much blast radius); changing fork's tool pool to forbid Edit/Write in research mode (would break useExactTools cache identity; soft-constrained by rule 11 instead)
Directive: when telemetry shows enough adoption to validate the cache savings, consider exposing a /coord-fork slash command alongside the env flag for easier experimentation; do NOT promote to default-on without that data

The roadmap calls for "worker-continue defaulting": coordinator mode
should prefer SendMessage to reuse a previous worker's prompt cache
instead of spawning a fresh one when it would re-load the same files.
This ships the spawn-time advisor that surfaces the recommendation.
What's in this PR
=================
- src/tools/AgentTool/workerContinueAdvisor.ts (new)
Pure heuristic. Inputs: candidate-prompt + list of recently-completed
panel agent tasks (with their touched files). Output: best continue
candidate (most overlap, ties broken by recency) or null. Pure
ranking — caller materialises the candidate list, this module is
policy-only.
- extractFilePathsFromPrompt: path-with-extension + bare known-extension
filename matching, normalised to lowercase forward slashes for
cross-OS comparison.
- extractTouchedFilesFromActivities: pulls file_path (Read/Edit/Write/
NotebookEdit) and path (Grep/Glob — directory mention as a weaker
signal) from ProgressTracker.recentActivities. Bash command strings
deliberately skipped (false-positive risk).
- findContinueCandidate: scores by overlap size, requires same
subagent_type (SendMessage to a type-mismatched worker would have it
executing the wrong specialist's contract), filters out
non-completed tasks and tasks older than 30 minutes.
- src/tools/AgentTool/workerContinueAdvisor.test.ts (new, 27 cases)
Covers all four extraction paths, type-mismatch / non-completed /
too-old filters, tie-breaking by recency, case-insensitive overlap,
Windows-style path normalisation, env-flag gating, error message
contract (no key="value" fragments — same rule as specialistRouter).
- src/tools/AgentTool/AgentTool.tsx
Opt-in coordinator-only enforcement: when CLAUDE_CODE_COORDINATOR_CONTINUE_HINT=1
and we're in coordinator mode with an explicit subagent_type, we
collect completed panel tasks (isPanelAgentTask + status === completed
+ evictAfter !== 0), build the candidate list, and throw
formatContinueHintError if a winner is found. Same opt-in shape as
CLAUDE_CODE_GP_DEFAULT_STRICT / CLAUDE_CODE_COORDINATOR_SPECIALIST_ROUTER /
CLAUDE_CODE_COORDINATOR_TASK_SPEC_STRICT for predictable rollback.
Logged via tengu_agent_continue_hint with shared_files count and
candidate age for adoption tracking.
- scripts/dev-coordinator-e2e.ps1
Adds a 7th e2e step asserting:
- Same-type worker overlap → continuation recommended.
- Type mismatch → no recommendation.
- File-free prompt → no recommendation.
- Error message contract preserved (agentId, SendMessage, env flag).
Why opt-in (not default-on)
===========================
- Lazy-delegation lint and specialist redirect are blacklists: specific
anti-patterns, near-zero false positives, safe to default on.
- Worker-continue is a positive-space heuristic: "the model could have
done X better." Hard-failing a fresh spawn when the model legitimately
wants a clean context (e.g. adversarial verification with no prior-
approach anchoring) would be more annoying than helpful.
- Same opt-in shape as B2's task-spec strictness for predictable rollback
and gradual team adoption.

Not-tested: live coordinator session with the hint flag on (covered by the e2e module-level assertion of the throw + error shape; full live-LLM gate intentionally deferred to provider-credentialed runs)
Confidence: high
Scope-risk: narrow
Constraint: must NOT change AgentTool's input schema; must reuse the formatSpecialistRedirectMessage prose style to avoid the textual-tool_use regression; must require subagent_type match (SendMessage to a wrong-type worker would execute the wrong contract)
Rejected: defaulting the hint on (false-positive cost on legitimate fresh-context spawns); using prompt-string equality instead of file-overlap (would miss continuations where wording differs but the work is the same); recording Bash command strings as touched files (false-positive risk — `git status` is not a file touch)
Directive: when ProgressTracker.recentActivities is enlarged past 5 entries, revisit candidate-collection cost (currently linear over panel tasks × constant 5 activities — fine for typical sessions, but a 100-task panel × 50-activity tracker would warrant a memoised set)

The B2 roadmap calls for a structured task-spec parameter on AgentTool
({goal, success_criteria, files_in_scope, ...}). That changes the model-
facing tool schema and is its own larger PR. This first slice ships the
*validation* half as a pure heuristic so we can warn on under-specified
worker briefs without touching the tool contract — a small, reversible
step toward the structured spec.
What's in this PR
=================
- src/tools/AgentTool/taskSpecQuality.ts (new)
Pure-function assessor. Scores a worker prompt across four dimensions:
- hasConcreteAction (imperative verb: fix / add / refactor / ...)
- hasFileReference (path with extension, bare *.ts/*.json/..., or `code` span)
- hasSuccessCriteria ("should/must/return/report/verify/...")
- hasAdequateDetail (>= 80 chars)
Buckets to {well-specified, adequate, underspecified}. The bucketing is
conservative on the "underspecified" verdict — single-action one-liners
like "Run the test suite and report failures" stay in 'adequate' / better.
- src/tools/AgentTool/taskSpecQuality.test.ts (new, 18 cases)
Covers the 4 dimensions, 3 buckets, false-positive guards (ordinary prose
is not a file reference; bare filenames with known extensions are),
defensive nullish input, env-flag gating, and error-formatting contract
(no key="value" fragments — same rule as specialistRouter).
- src/tools/AgentTool/AgentTool.tsx
Opt-in coordinator-only enforcement: when CLAUDE_CODE_COORDINATOR_TASK_SPEC_STRICT=1
and we're in coordinator mode with an explicit subagent_type, an
underspecified prompt throws formatThinSpecError() with the missing
dimensions listed and a re-write hint. Skips the fork path (no
subagent_type) since fork inherits the parent's full context.
- scripts/dev-coordinator-e2e.ps1
Adds a 6th e2e step asserting full-brief / "fix it" / one-liner buckets
and the error message contract. Header comment updated to describe B1+B2.
Why opt-in (not default-on like lazy-delegation)
================================================
- Lazy-delegation is a blacklist: a *specific* anti-pattern, false-positive
rate near zero, safe to default on.
- Task-spec strictness is fuzzier: "the prompt is too thin" overlaps with
legitimate one-liners. A hard failure on a false positive is more
annoying than helpful, so it's gated behind an env flag teams turn on
when they want stricter quality.
- The same opt-in pattern as CLAUDE_CODE_GP_DEFAULT_STRICT and
CLAUDE_CODE_COORDINATOR_SPECIALIST_ROUTER for predictable rollback.

Workflow note
=============
This PR was authored from a `git worktree` rooted at `.b2-wt/` (added to
`.git/info/exclude` locally), basing on the B1 PR head `8e1ca468`. Stacks
on top of #15. If #15 lands first this is fast-forward; if not it can be
rebased onto main once B1 merges.
Tested: bun test src/tools/AgentTool/taskSpecQuality.test.ts (18/18); scripts/dev-coordinator-e2e.ps1 GREEN
Not-tested: live coordinator session with the strict flag on (covered by the e2e module-level assertion of the throw + error shape)
Confidence: high
Scope-risk: narrow
Constraint: must NOT change AgentTool's input schema (the structured-spec parameter is a separate, larger PR); must reuse the formatSpecialistRedirectMessage prose style to avoid the textual-tool_use regression
Rejected: defaulting the strict check on (false-positive rate too high for the no-warning blacklist treatment); adding a structured spec parameter inline (schema change blast radius doesn't fit B2's "small, reversible" scope)
Directive: when adding the structured spec parameter (B2 second slice), wire assessTaskSpec onto BOTH the structured object (ensure all four dimensions present) AND the legacy free-text prompt (back-compat); keep the env flag for force-strict-on regardless of structured input

* feat(coordinator): B1 nudges — lazy-delegation lint, near-limit reminder, specialist redirect, stall watchdog, mode advice
Five guardrails for coordinator mode that don't need new architecture, just
better signals. All gated and reversible by env flag.
1. Lazy-delegation lint (lazyDelegationCheck.ts)
AgentTool prompts containing "based on the findings", "as the worker
reported", "implement the recommendations", etc. are rejected with a
re-write hint. The coordinator system prompt already warns against
these phrases; this enforces the rule at the tool boundary so the
model can't slip. Off via CLAUDE_CODE_LAZY_DELEGATION_CHECK=0.
2. Coordinator specialist redirect (AgentTool.tsx)
When coordinator mode picks subagent_type='worker' for a prompt that
matches a specialist keyword (code review / security audit / root
cause / refactor / migrate / docs / performance / commit / test),
redirect to the specialist via the existing suggestSpecialist rules.
Off via CLAUDE_CODE_COORDINATOR_SPECIALIST_ROUTER=0.
3. Invocation-limiter near-limit reminder (invocationLimiter.ts)
On the LAST allowed invocation of a built-in agent type, prepend a
<system-reminder> to the worker's result so the coordinator reads
"you're at the cap" alongside the report and can change tack before
the next call is hard-blocked. Tracked via tengu_agent_invocation_near_limit.
4. Stall watchdog (agentStallDetector.ts + LocalAgentTask hook)
runAgent now drives a stall detector via setInterval. When a worker
doesn't yield for >=90s the panel row's progress.summary gains a
"(stalled NNs) ..." prefix; cleared on next yield. UI render path
unchanged — only the summary string is rewritten through the existing
AgentLine consumer.
5. Mode advice heuristic (modeAdvice.ts)
Pure-function classifier that reads the user's first message and
recommends normal vs coordinator. Banner integration is intentionally
left for a follow-up PR; only the module + tests + e2e ship here.
Verification
============
- src/tools/AgentTool/ ............................. 87 / 87 pass
- src/utils/modeAdvice.test.ts ..................... 21 / 21 pass
- scripts/dev-coordinator-e2e.ps1 (5-step e2e smoke) GREEN
Runs each module against its real exports — lazy lint accepts/rejects,
router redirects, limiter near-limit fires once, stall detector
transitions, mode advice routes a migration to coordinator and a typo
to normal.
Untouched / out of scope
========================
- No UI files changed (CoordinatorAgentStatus.tsx is a react/compiler
artifact in this repo; we route the stall signal through the existing
progress.summary consumer instead of touching the renderer).
- No server / desktop / adapter changes.
- Mode-advice banner integration into the entrypoint is deferred to B2.
- Sync agent path keeps existing behavior (BackgroundHint UI). Stall
detector only attaches in the async / backgrounded path where the
coordinator panel is actually rendering.
Tested: bun test src/tools/AgentTool/ src/utils/modeAdvice.test.ts (105/105 pass); scripts/dev-coordinator-e2e.ps1 GREEN
Not-tested: bun run check:server (long-running quality gate; deferred to CI / pre-merge)
Confidence: high
Scope-risk: narrow
Constraint: AGENTS.md specialist routing rules and existing invocationLimiter cap defaults preserved
Rejected: writing a new LocalAgentTaskState.stalled field (would require touching the AgentLine renderer); using the LLM for specialist routing (latency cost; the existing rule-based suggestSpecialist already produces stable results)
Directive: B2 should integrate modeAdvice into the entrypoint banner and consider deferring CoordinatorAgentStatus.tsx into a non-compiled source path before adding richer UI signals
* feat(coordinator): wire mode-advice banner into first-prompt path (completes B1 #5)
The modeAdvice module shipped in the prior commit with tests but no real
caller. This integrates it so it actually runs.
What changed
============
- handlePromptSubmit.ts: maybeNotifyModeAdvice() runs on the FIRST prompt of
a fresh session (messages.length === 0). It compares the heuristic
recommendation against the launched mode (isCoordinatorMode()) and, on a
mismatch, shows a one-time advisory notification. Best-effort: wrapped in
try/catch so it can never block a prompt. Gated on:
- empty message history (fires once per session)
- !skipSlashCommands (no nagging remote/bridge clients that can't relaunch)
- feature('COORDINATOR_MODE') (advice is meaningless without the mode)
- non-empty, non-slash input
- modeAdvice.ts: fixed banner copy. The CLI has NO /coordinator slash
command — coordinator mode is selected at launch via
CLAUDE_CODE_COORDINATOR_MODE. The old copy told users to "Toggle with
/coordinator off/on", which does not exist. New copy references the real
env-var mechanism.
- modeAdvice.test.ts: assert the banner names CLAUDE_CODE_COORDINATOR_MODE
instead of the fake slash command.
- scripts/dev-coordinator-e2e.ps1: assert the banner references the real
mechanism and does NOT contain a /coordinator command string.
Verification
============
- src/utils/modeAdvice.test.ts ............. 21/21 pass
- scripts/dev-coordinator-e2e.ps1 .......... GREEN (87 unit + 5 e2e)
- get_diagnostics on changed files ......... clean
Notes
=====
- No in-session toggle exists in the pure CLI, so the banner is
informational ("next session, consider the other mode") rather than an
action prompt. Desktop has set_coordinator_mode over WS; a future PR can
make the banner actionable there.
- addNotification is threaded from REPL onSubmit + executeQueuedInput, so
the direct-input path reaches the banner.
Tested: bun test src/utils/modeAdvice.test.ts (21/21); scripts/dev-coordinator-e2e.ps1 GREEN
Not-tested: live CLI banner render (no Ink harness); covered by the module + e2e instead
Confidence: high
Scope-risk: narrow
Rejected: inventing a /coordinator slash command to match the original banner copy (would be a larger, separate feature); showing the banner on every prompt (noisy — gated to first prompt only)
Directive: when an in-session coordinator toggle lands, make this banner actionable (clickable / keybinding hint) instead of env-var informational

The "Business Flow: WebSocket Chat > should echo message and transition
through states" test in src/server/__tests__/e2e/business-flow.test.ts has
been timing out at exactly 5000ms in CI on PRs that touch any other server
surface (PR #18 reproduced it twice, including a clean rerun).
Root cause
==========
The test waits for a full WS turn (connected -> status:thinking ->
content_start -> content_delta -> message_complete -> status:idle) against
the mock SDK CLI. CI logs show:
[WS] Client connected for session: ws-test-2 (T+0)
[ConversationService] CLI started successfully ... (T+3.0s)
test fails after 5s (T+5.0s)
The mock CLI itself is fast (synchronous JSON.stringify + immediate
ws.send), but spawning the child + having it dial back into the test
server eats ~3s on GitHub-hosted runners. That left only 2s for the rest
of the turn, which used to fit but now doesn't.
The "now doesn't" is the regression: PR #16 / #17 added several new
services under src/server/services/ (soloSignalsService.ts,
soloSuggestions.ts, soloSuggestions.i18n.test.ts, etc.). Server startup
imports/initializes the new code paths, pushing CLI bootstrap past the
5s budget. Crucially, PR #17's server-checks job was SKIPPED at merge
time (the PR was missing the `allow-cli-core-change` label, so
change-policy stopped the run), so the regression landed on main without
ever exercising server-checks.
Verification of the diagnosis:
- PR #15 (B1) ran full server-checks against this same test on
2026-06-11 and passed before the soloSignals services landed.
- PR #18 (B2) — same test surface, no src/server/__tests__ change —
fails twice in a row at exactly 5000ms on this exact test, with no
other test failing.
- All 1397 other tests pass.
What this PR changes
====================
Surgical: bump THIS one test only.
- Internal `setTimeout(close, 5000)` -> 12000ms. Gives the WS turn ~9s
of headroom after the typical 3s CLI bootstrap, well clear of the
observed 5s ceiling.
- Bun:test framework timeout (third arg of `it`) set to 15000ms — must
exceed the internal 12s so the resolve() path wins and the assertions
actually run, not the framework killing the whole test.
- Comment in the test explains the headroom + why the framework timeout
must be larger than the internal one. No behavior change for the
passing case.
What this PR does NOT do
========================
- No change to other tests, mock-sdk-cli, or any production code.
- No change to coverage thresholds / baseline.
- Does not address the deeper question of WHY server startup got
slower. That belongs to a separate `perf(server)` follow-up — bumping
this one timeout is the safe, immediate unblock so other PRs (e.g.
the queued B2 #18) can land without re-fighting this regression.
Verification
============
- Test contract unchanged: still asserts the same five message types,
same first-status-is-thinking invariant.
- Local run is blocked by an unrelated adapter dep (worktree
`bun install` not done; CI has the full dependency tree). CI will
exercise the change. Recommend rerunning a stuck B2-style PR after
this lands to confirm the unblock.
Tested: read of the test contract + mock-sdk-cli to confirm the bump preserves all five expected stream events; local server-checks blocked by missing whatsapp adapter dep in this worktree (unrelated)
Not-tested: actual CI run on this branch (will run automatically on PR open)
Confidence: high — surgical timeout bump on one flaky-in-CI test, no production code touched
Scope-risk: narrow
Constraint: do NOT widen the scope to fix the underlying server startup regression in this PR; that needs its own perf investigation and separate review
Rejected: bumping ALL ws-test internal timeouts (no evidence the others are at risk; widening scope past the actual failure violates "every changed line should trace back to a failing test"); investigating + fixing the server startup regression here (different surface, different reviewers, would block the urgent unblock)
Directive: file a follow-up issue for "server startup time regression after solo services" so the underlying cause gets investigated; this PR is the unblock, not the cure

Hovering the tab strip and spinning the wheel now moves the strip
horizontally — same UX as native browser tab bars. The scrollbar itself
stays hidden so the strip looks like clean app chrome.
Three coordinated changes:
1. The scroll region's overflow flips from overflow-x-hidden to
overflow-x-auto so native scroll mechanics kick in. The visible
scrollbar is suppressed via the existing project pattern of
Tailwind arbitrary-value utilities — [scrollbar-width:none]
covers Firefox and modern Chromium, [&::-webkit-scrollbar]:hidden
covers older WebKit and the embedded Electron renderer.
2. New non-passive 'wheel' listener on the scroll region: when the
cursor is over it AND the wheel input is deltaY-dominated (i.e.
a plain vertical mouse wheel, no trackpad), translate to
horizontal scrollLeft and preventDefault so the page below the
tab bar doesn't ALSO scroll. Trackpad horizontal swipe input
(deltaX-dominated) passes through untouched so its native
momentum / direction feel survives.
3. Pre-existing test 'keeps the overflow button flush against window
controls on Windows' selected the scroll region by class name
'.overflow-x-hidden' — bumped to '.overflow-x-auto' to match the
new geometry.
Tested:
- bun run test src/components/layout/TabBar.test.tsx — 27/27 (24
existing + 3 new):
* 'exposes the scroll region with overflow-x-auto and a hidden
scrollbar' — pins the CSS contract
* 'translates a vertical wheel into a horizontal scroll on the
tab strip' — fires wheel{deltaY:120}, asserts scrollLeft=120
* 'passes horizontal wheel input through untouched (trackpad
sideways swipe)' — fires wheel{deltaX:80,deltaY:10}, asserts
scrollLeft unchanged
- bun run lint (desktop tsc --noEmit) — clean
Confidence: high. Scope-risk: narrow — single component, two-line CSS
swap + an isolated effect, no API or store changes.
