Stacked on #934 — that PR (also fixing #859) adds the structured SkillDiagnostic collection (SkillsManager.diagnostics / recordDiagnostic() / getSkillDiagnostics()) and the settings-page diagnostics panel. This PR keeps only the remaining gaps on top of it, so the diff stays minimal if #934 merges first and gets squashed.
Misleading error still hides the common cause.fix(skills): safely serialize skill frontmatter #934's recordDiagnostic() reports the YAML exception, but the single most common trigger — unescaped double quotes in the description — still requires the user to read the raw YAML error and open the file. A targeted hint points at the exact line and the fix.
Diagnostics can disappear on re-scan (gray-matter cache poisoning). gray-matter keeps a global content-keyed cache that it populates before parsing. A frontmatter that throws on first parse is cached with an empty data object, and every later parse of the same content silently returns that empty object instead of re-throwing — so a re-scan (watcher event, manual refresh) resurfaces the misleading "missing required 'name' field" symptom and drops the diagnostic.
Overlapping discovery scans can interleave. File-watcher events start concurrent discoverSkills() runs; an older scan finishing after a newer one can append a stale diagnostic for an already-repaired skill.
Frontmatter serialization reflows on every mode change.updateSkillModes() rewrites the file with js-yaml's default lineWidth: 80, reflowing long plain descriptions into folded block scalars (>-1) on every mode toggle — noisy diffs and format churn. createSkill() had the same exposure.
Settings crashes when skillDiagnostics is absent.fix(skills): safely serialize skill frontmatter #934 made the field optional on ExtensionState, but SkillsSettings read it without a fallback — any render without it (and 14 webview tests in the unit-test CI job) crashed with Cannot read properties of undefined (reading 'length').
Missing translations.fix(skills): safely serialize skill frontmatter #934's new settings:skills.diagnostics.* i18n keys were only added to en, which fails the check-translations CI job (all 17 non-English locales).
Test coverage. The new handleUpdateSkillModes postMessage path, the malformed-load branches, updateSkillModes' serialization, and the extension-host → watcher → webview diagnostics flow had no tests.
loadSkillMetadata() now parses with explicit empty options (matter(fileContent, {})), bypassing gray-matter's global content cache so a malformed skill reports the same parse error on every scan instead of the first throw being cached as an empty data object.
When the parse throws, a small module helper (getFrontmatterLine()) extracts the raw top-level description: line with its file line number; the "unescaped double quotes" console.error hint is only emitted when the parser error's mark is located on that exact line — so a valid quoted description plus an unrelated YAML error elsewhere does not produce a misleading hint.
discoverSkills() is a non-async serializer chaining each run onto a discoveryChain promise; the body moved to performDiscovery(). Overlapping watcher-triggered scans no longer interleave, so an older scan can no longer append a stale diagnostic after a newer scan has observed the repaired file.
Both createSkill() and updateSkillModes() now pass lineWidth: -1 (via a small typed alias, since gray-matter's bundled typings predate its js-yaml dump-options passthrough), keeping long plain values on a single line.
Output for plain descriptions stays byte-identical to the previous format; values with YAML special characters (double quotes, booleans like yes) are quoted/escaped automatically and always round-trip.
skillDiagnostics falls back to [] (same pattern as the existing skills handling), so the component no longer crashes when the optional ExtensionState field is absent. Fixes the 14 webview test failures in the unit-test CI job.
Adds settings:skills.diagnostics.title / description to all 17 non-English locales (translated per locale), fixing the check-translations CI failure.
6. Tests
SkillsManager.spec.ts (gray-matter vi.mocked with the real parser as default implementation): a serialization regression test (a delayed older scan cannot append stale diagnostics), a gray-matter cache-poisoning regression test (a re-scan of unchanged malformed content must keep reporting the parse failure), the exact issue [Bug] SKILL.md YAML parsing fails silently when description contains unescaped double quotes #859 content (hint + diagnostic logged, misleading "missing required 'name' field" absent), a no-false-hint case with a valid quoted description and an error on another line, a non-Error parse failure exercising recordDiagnostic's defensive fallbacks, unterminated frontmatter with a dangling quote (diagnostic recorded, hint absent), create-path round-trip cases, and an updateSkillModes serialization round-trip case.
skillsMessageHandler.spec.ts: new handleUpdateSkillModes suite (success, empty-slug clearing, omitted newSkillModeSlugs → undefined with a non-empty diagnostics list forwarded, missing fields, manager unavailable, rejected promise).
ExtensionStateContext.spec.tsx: the skills-message test now asserts the transition that clears stored skills/diagnostics, including a message that omits skills entirely.
api-get-skills-state.spec.ts: unit coverage for the new test-only getSkillsState() accessor (skills + diagnostics returned; empty arrays when the manager is unavailable).
apps/vscode-e2e/src/suite/skills-diagnostics.test.ts (new): a real extension-host smoke test of the diagnostics flow — writes a healthy and a malformed (double-quoted description with unescaped inner quotes, the exact [Bug] SKILL.md YAML parsing fails silently when description contains unescaped double quotes #859 failure mode) SKILL.md into the workspace's .roo/skills on real disk via atomic sidecar+rename writes so the watcher only observes complete files, waits for the extension host's file watcher to re-discover, asserts the malformed skill is omitted with a diagnostic pointing at it while the healthy skill is unaffected, then repairs the frontmatter and asserts the watcher clears the diagnostic and loads the fixed skill. Teardown removes only the skill directories this suite created.
Merge #934 first, then this PR (no rebase needed: this branch already sits on #934's head plus upstream/main).
Updated this round (main refresh): merged upstream main (58341d882). The only conflict was the frontmatter-parse block in SkillsManager.ts - this branch's parse-error handling (which already drops the unused content: body binding main removed) kept; everything else auto-merged.
Verification at this merge: SkillsManager + skillsMessageHandler + api-get-skills-state suites 141 passed; webview SkillsSettings + ExtensionStateContext 46 passed; ESLint --max-warnings=0 clean on every touched file (src and webview) with main's re-enabled unused-variable lint; tsc --noEmit clean (src + webview); Prettier clean on touched files and on the PR merge commit.
Skill-loading diagnostics show error details and, when available, line and column locations.
Settings identify affected skill files and explain how to correct their YAML frontmatter.
Skill metadata and diagnostics are available through the extension API.
Bug Fixes
Valid skills continue to load when others have errors, and diagnostics update as skills change.
Skill saves preserve existing file permissions and clean up incomplete files after failures.
Updates outside configured skill directories are rejected with a localized error.
Stale temporary skill files are cleaned up while recent in-progress files are retained.
Localization
Diagnostic messages and expanded settings text are available in supported languages.
Skill discovery now reports YAML frontmatter failures as structured diagnostics with source paths and optional locations. The API and webview carry and display diagnostics with skill metadata. Skill creation and mode updates use serialized atomic writes, path checks, and cleanup. Tests and localized strings cover these changes.

Summary
Diagnose and safely persist skill frontmatter src/services/skills/SkillsManager.ts, src/services/skills/__tests__/SkillsManager.spec.ts, packages/types/src/skills.ts, src/shared/skills.ts
Discovery records YAML parse failures with line and column data and exposes them through getSkillDiagnostics(). Creation and mode updates use shared YAML serialization, per-directory queues, path checks, and atomic temporary-file writes. Tests cover diagnostics, cleanup, disposal, concurrency, and YAML round-tripping.
Expose diagnostics through API and skills messages packages/types/src/api.ts, packages/types/src/vscode-extension-host.ts, src/extension/api.ts, src/extension/__tests__/api-get-skills-state.spec.ts, src/core/webview/skillsMessageHandler.ts, src/core/webview/__tests__/skillsMessageHandler.spec.ts
The extension API and skills messages return diagnostics with skill metadata. They return empty arrays when the manager is unavailable or retrieval fails.
Store and display diagnostics webview-ui/src/context/ExtensionStateContext.tsx, webview-ui/src/components/settings/SkillsSettings.tsx, webview-ui/src/components/settings/__tests__/*, webview-ui/playwright/gallery/stories.tsx
The webview stores diagnostics from skills messages and renders a warning with paths, messages, and optional locations. Tests and a gallery story cover the state shape and display.
Validate and localize apps/vscode-e2e/src/suite/skills-diagnostics.test.ts, src/i18n/__tests__/skills-error-locales.spec.ts, src/i18n/locales/*/skills.json, webview-ui/src/i18n/locales/*/settings.json
E2E and unit tests cover malformed and repaired skills, required locale placeholders, and diagnostics text. Skill error locales add the outside_skills_root message; settings locales add skill diagnostics text and other settings translations.

Merge Risk: Low · up to 50461
The diagnostics display works on the described paths, but its reorder test can miss misplaced messages. A rare cross-host pause can also prevent a skill update from being saved. These are bounded risks to address or explicitly accept before merging.
Security Architecture Review
Security architecture risk:🔵 Low · up to ea343
The change improves error visibility and consistency during overlapping scans. No concrete privilege-escalation or injection path was established, but trust expectations for external callers and some failure-recovery behavior remain uncertain.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
observed — The snapshot includes discovered global and current-project skills from .roo and .agents directories, including mode-specific directories. The new method exposes their metadata and diagnostic paths through the extension export; it is not a new case in the inspected IPC command dispatcher.
Trust Boundaries and Controls
observed — getSkillsState accepts no caller-controlled selector, performs no filesystem operation, and returns metadata rather than skill instructions. It has no caller-specific authorization or source filtering. The observed direct consumer is the end-to-end test suite; the supplied evidence does not establish a less-trusted production consumer.
observed — The API method itself does not mutate state, but its return value is not an immutable snapshot: metadata objects come directly from the manager map, and diagnostics are copied only at the array level. These accessors do not establish an isolation boundary for callers.
Resilience and Maintainability Implications
inferred — An already-running discovery can publish after disposal because publication has no disposed-state guard. Normal provider cleanup removes the manager reference, limiting continued API reachability. A security-sensitive consumer using a retained manager reference was not established, so this is not retained as an introduced security concern.
Hardening Proposals
proposed — If test-only access or caller isolation is intended as a security guarantee, enforce that boundary explicitly and return detached snapshot objects. Documentation alone does not provide either guarantee; this is a hardening proposal, not a verified vulnerability.

Explanation
The PR includes substantial changes with no demonstrated link to [#859]: SkillsManager adds stale-sidecar sweeps and retries, cross-instance directory locking, disposal cleanup, permission preservation, and path/symlink validation for writes. The Catalan settings diff adds unrelated indexing, provider, context, auto-approval, terminal, and diff strings; the summary also identifies write-delay-labels.spec.ts as an auto-approval test. The YAML-safe serialization for createSkill() and the diagnostics translations support the linked issue, but these other changes do not.
Resolution
Move the stale-sidecar lifecycle, locking, permission, and path-policy changes, along with unrelated settings translations and the auto-approval label test, to a separate PR. Keep the YAML parse diagnostics, safe frontmatter serialization, and related UI translations and tests.
Full details: Security Boundaries
Explanation
Two security boundary failures remain in src/services/skills/SkillsManager.ts: - Line 791 creates a sidecar with default permissions before line 818 applies the existing file mode. With umask 022 and searchable directories, another local user can read secrets from a 0600 skill during a mode update. The base revision writes directly to the existing file. - Lines 1294–1309 check containment before lines 805–820 use the paths again. A process with write access to the parent can move the skill directory outside the root and replace it with a symlink after validation. The rename can then publish outside the skills-root allowlist.
Resolution
Create sidecars with restrictive permissions from the start, then apply the intended mode before publication. Use a race-safe containment mechanism that prevents or detects ancestor relocation during publication.
Full details: Persistence Integrity
Explanation
The prior data-loss concerns remain. SkillsManager.ts:1272-1310 reads a skill before the new staged write and path checks; an external edit during those steps can be overwritten by the rename at line 820. The new directory lock covers only this process. At lines 879-919, concurrent creates can both pass the existence check, then the new queue publishes both without a conflict check; the second rename replaces the first skill. Both races existed before the PR, but the added staging and queue extend their exposure.
Resolution
Protect mode updates against conflicting external edits through publication and report conflicts. Publish new skills with atomic create-if-absent semantics instead of replacing an existing file.
Full details: Regression Evidence
Explanation
The new atomic writer aborts when the target stat returns a coded error, but no focused test covers that branch. SkillsManager.spec.ts:2584-2625 covers successful mode preservation; the EIO test at lines 2656-2692 covers rename failure instead. Without a stat-failure test, a regression could publish a file with default permissions.
Resolution
Add a test that makes the publish-time target stat fail with EACCES or EIO. Verify that the error propagates, the staged file is removed, and rename does not occur.
Full details: Lifecycle Resource Cleanup
Explanation
The prior cleanup failure remains. updateSkillModes stages beside the resolved target (SkillsManager.ts:1261-1273, 780-782), but the restart sweep checks only roots and direct non-symlink directories for .SKILL.md.*.tmp (:165-195). A crash can leave a sidecar for a deeper or differently named symlink target indefinitely. The single retry (:143-150) also misses a sidecar created by another host shortly before that host crashes, if it is still fresh at retry time.
Resolution
Clean up abandoned sidecars for all supported resolved target names and directories. Revisit sidecars that become stale after the retry. Protect active writes across processes and cancel cleanup tasks on disposal.

….md safely
SKILL.md files whose description contains unescaped double quotes failed to parse silently: gray-matter's YAMLException was swallowed by the outer catch and users only saw a misleading "missing required 'name' field" log (issue Zoo-Code-Org#859).
- Catch gray-matter parse errors separately in loadSkillMetadata and log the actual YAML syntax error, with a hint pointing at unescaped double quotes in the description line
- Build createSkill frontmatter as data and serialize via matter.stringify so special characters (double quotes, YAML booleans such as "yes", etc.) are quoted automatically and created skills always load
- Pass lineWidth: -1 to the dump options (with a typed alias for gray-matter's outdated options typings) to keep long plain scalars on one line and prevent updateSkillModes rewrites from reflowing values into folded block scalars
- Add regression tests covering both the load path (invalid YAML is skipped with the real cause logged, no misleading field error) and the create path (quoted frontmatter round-trips and loads on re-discovery)
- Add settings:skills.diagnostics.title/description to all 17 non-English
locales; the diagnostics panel keys from Zoo-Code-Org#934 were only in en, which
failed the check-translations CI job (scripts/find-missing-translations.js).
- Add an updateSkillModes unit test (modeSlugs written, then cleared;
description survives the gray-matter round-trip un-reflowed), closing the
last patch-coverage gap on the SKILL.md serialization lines.
Zoo-Code-Org#934 added skillDiagnostics to ExtensionState as an optional field but
SkillsSettings read it without a fallback, so every SettingsView render
where the field is absent crashed with "Cannot read properties of
undefined (reading 'length')". This broke 14 webview tests in the
platform-unit-test CI job (SettingsView.change-detection and
SettingsView.unsaved-changes).
Mirror the existing skills handling: fall back to [] via useMemo.
…ndary
Add apps/vscode-e2e/src/suite/skills-diagnostics.test.ts covering the
real extension host -> SkillsManager -> file watcher flow that lower
layers cannot reach:
- Writes a healthy and a malformed (issue Zoo-Code-Org#859 content) SKILL.md into
the workspace's .roo/skills directory on real disk.
- Waits for the extension host's file watcher to re-discover and asserts
the malformed skill is omitted from getSkillsState().skills while a
diagnostic points at it, and the healthy skill is unaffected.
- Repairs the frontmatter in place and asserts the watcher clears the
diagnostic and loads the fixed skill.
Supports this with a test-only getSkillsState() on the exported
extension API (mirroring the existing getTaskHistoryItem pattern),
backed by ClineProvider.getSkillsManager().
Verified locally: bundle + webview build + USE_MOCK=true test:run with
TEST_FILE=skills-diagnostics.test.js -> 1 passing.
Unit coverage for the new extension API method used by the skill
diagnostics e2e smoke test: returns the skills manager's metadata and
diagnostics, and empty arrays when the manager is unavailable.
Closes the codecov/patch/webview-patch gap (4 not-fully-covered lines):
- ExtensionStateContext.spec.tsx: dispatch real "skills" messages through
the provider and assert skills/skillDiagnostics update, including the
empty-array default when the message omits skillDiagnostics.
- SkillsSettings.spec.tsx: render without skillDiagnostics in state
(the exact shape that used to crash) and render diagnostics with and
without line/column locations so every branch of the location
formatting is exercised.
Local: both specs 45/45 passing; lcov confirms all patch lines and
branches in both files are taken.
This test covers [] only. Add a case that omits newSkillModeSlugs, then assert that handleUpdateSkillModes() passes undefined to updateSkillModes() and posts the refreshed state. As per coding guidelines, include false or unset cases when defaults could hide omissions.

…se frontmatter deterministically
Addresses the CodeRabbit review findings and completes the patch coverage:
- Serialize discoverSkills() runs through a promise chain so overlapping
watcher-triggered scans never interleave; an older scan can no longer
append a stale diagnostic after a newer scan has observed the repaired
file.
- Only emit the unescaped-double-quotes hint when the parser error is
located on the description line itself, so a valid quoted description
plus an unrelated YAML error elsewhere no longer produces a misleading
hint.
- Parse SKILL.md frontmatter with explicit empty options so gray-matter's
global content-keyed cache is bypassed. The cache is populated before
parsing, so a frontmatter that throws on first parse is cached with an
empty data object and every later parse of the same content silently
returns that object instead of re-throwing - which resurfaces the
misleading "missing required 'name' field" symptom from issue Zoo-Code-Org#859.
Tests:
- SkillsManager.spec: regression test that a delayed older scan cannot
append stale diagnostics (serialization), a regression test that a
re-scan of unchanged malformed content keeps reporting the parse
failure (gray-matter cache poisoning), a no-false-hint case with a
valid quoted description and an error on another line, and a non-Error
parse failure exercising recordDiagnostic's defensive fallbacks
(gray-matter is now vi.mocked with the real parser as the default
implementation).
- ExtensionStateContext.spec: the skills message test now asserts the
transition that clears stored skills/diagnostics, including a message
that omits skills entirely.
- skills-diagnostics e2e: the malformed fixture is now a double-quoted
description with unescaped inner quotes (the exact Zoo-Code-Org#859 failure mode),
skill files are written atomically (sidecar + rename) so the watcher
only observes complete files, and teardown removes only the skill
directories the suite created.
- api-get-skills-state.spec: document why the partial test doubles need
as-unknown-as casts.
- skillsMessageHandler.spec: cover the omitted newSkillModeSlugs case
(passes undefined, still refreshes the posted state).
e2e teardown: only removes the skill directories this suite created; pre-existing fixtures under .roo/skills are left intact.
api-get-skills-state.spec: the partial doubles need a documented double-assertion; added a beforeEach comment explaining why it is a last resort.
serialize overlapping discovery runs (major): discoverSkills() is now a non-async serializer chaining each run onto a discoveryChain promise; a delayed older scan can no longer append a stale diagnostic after a newer scan observed the repaired file (regression test added).
quote hint scoped to the failing line: the "unescaped double quotes" hint is only emitted when the parser error mark is on the description line itself (regression test with a valid quoted description plus an error on another line).
state transition that clears diagnostics: the skills message test now asserts stored skills/diagnostics are cleared, including a message that omits skills entirely.
nitpick (typed message fixture / non-empty diagnostics assertion): the omitted-newSkillModeSlugs test declares a WebviewMessage instead of an as cast, and asserts a concrete non-empty diagnostic list is forwarded.
Additional root-cause fix found while making the e2e deterministic: gray-matter keeps a global content-keyed cache that it populates before parsing, so a frontmatter that throws on first parse was cached with an empty data object and every later parse of the same content silently returned that object instead of re-throwing (resurfacing the misleading "missing required name field" symptom). loadSkillMetadata() now parses with explicit empty options to bypass the cache, with a unit-level regression test that a re-scan of unchanged malformed content keeps reporting the parse failure.

src/services/skills/SkillsManager.ts:775 Minor · Security & Privacy · Quick win
Stage the SKILL.md temp file with private mode before writing content.
writeSkillFileAtomically creates the temp file with flag: "wx" and no mode. Node then uses the default 0o666 mode, limited by the umask. Under a common 022 umask, the temp file is 0644. The full SKILL.md content is written to that file before fs.chmod applies the target's mode. A user-restricted SKILL.md, such as 0600, therefore has its contents readable by other local users during the staging window. This applies when the skills directory is traversable by those users.
Create the temp file with private mode. Keep the existing target-mode and default-mode behavior after the write:
if (existingTarget && typeof existingTarget.mode === "number") {
await fs.chmod(temporaryPath, existingTarget.mode & 0o777)
+ } else {+ // Restore the process default mode for a new file, as createSkill expects.+ await fs.chmod(temporaryPath, 0o666 & ~process.umask())
}
The else branch keeps the default mode for a missing target. Without it, new skills created through createSkill would be 0600 instead of the umask default. Confirm the process.umask() read is acceptable for this code path, because it is documented as deprecated for thread-safety reasons.

Update writeSkillFileAtomically to create the exclusive temporary SKILL.md with
private permissions before writing its contents. Preserve the existing-target
mode behavior and restore the normal umask-respecting default mode for a new
skill after writing; establish a safe way to determine that mode rather than
assuming process.umask() is acceptable.

Failed pre-merge checks:
- Out of Scope Changes check:
Move these changes and their tests to separate pull requests: the atomic
SKILL.md write path, stale-sidecar cleanup, directory locks and symlink or
realpath handling, path containment for mode updates, permission preservation,
disposal handling, rollback of created skill directories, the
outside_skills_root locale entries and skills-error-locales test, and the
write-delay-labels locale changes and spec. Keep the parse diagnostics,
gray-matter cache bypass, discovery serialization, lineWidth serialization,
settings diagnostics wiring, diagnostics translations, and the tests that
directly cover them.
- Regression Evidence:
Update the create rename-failure test to assert
`expect(mockRmdir).toHaveBeenCalledWith(p(GLOBAL_ROO_DIR, "skills",
"rename-fails"))` and `expect(mockRm).not.toHaveBeenCalled()`. Keep the existing
original-error, temporary-unlink, and `activeTempFiles` assertions.
- Security Boundaries:
Use trusted directory and file handles for the complete update. Open the
configured skills root and target parent with no-follow semantics where
supported, verify containment through those handles, create the temporary file
exclusively relative to the trusted parent, apply its mode through the handle,
and rename it relative to that handle. Do not perform path-based `fs.chmod()` or
`fs.rename()` after a path-only allowlist check.

Blocked by a zombie job, not by a failing test — this needs someone with admin rights, not another push.
The required context(s) below have been in_progress since 2026-11-05T16:41:03Z / 2026-11-05T16:36:52Z — about two and a half days — on head 2a25a2b9f9 (fix/skill-frontmatter-yaml-859). Their workflow runs have already finished successfully, and every step inside the job has completed. The job record simply never received its terminal update, so the required check will never report no matter how long it is left.
Nothing we can do moves these: POST /repos/{owner}/{repo}/actions/runs/{run_id}/rerun-failed-jobs returns 403 Must have admin rights to Repository. for this token, and the runs are not failed anyway — they are complete. A cancel of the stuck run (or an admin re-run of the job) would clear it; the only lever we hold is a new push, which would burn a full CI cycle to fix a bookkeeping fault and would not change the review verdict. Flagging it here so the PR is not mistaken for one that is still being tested.
For reference, the other required contexts on this head are completed/success.
Refresh of a stale base: the recorded base is 73931fe and upstream main has moved 2 commits since that point (git rev-list --count 73931fe..5319fe9), so the lane now runs against the tree reviewers are reading, and the coverage lanes get a fresh worker generation.
This is a merge, not a rebase: no lane commit was rewritten or amended, and the 49 commits on this branch keep their identities. The merge carries only main's side - 21 files, 130 insertions, 65 deletions - and its single dependency change is @copilotkit/aimock 1.35.0 to 1.47.0 under apps/vscode-e2e devDependencies. src/eslint-suppressions.json comes over as main's own version, whose numeric suppression total is 2868 against 2870 on this branch, so no count rises.
Why push it: measurement. The required leg platform-unit-test (ubuntu-latest) at 46bc5d2 was red while reporting 196 test files and 4,250 tests passing, with 8 unhandled EnvironmentTeardownError rejections under the coverage loader that vitest attributed to core/task/__tests__/flushPendingToolResultsToHistory.spec.ts while stating that the origin file does not mean the error was thrown there. That file is not among this PR's 56 changed files. A run at a current base is the cheapest available test of whether that shape follows the harness or the lane.
Attribution on this branch's 49 commits, measured from author.login: 45 are account-linked (easonLiangWorldedtech 32, easonliang28 11, taltas 2); 4 are not (eason.liang@worldedtech.com 3, dsh@local 1). Protect Main requires extra approval for unattributed changes.

- Out of Scope Changes check:
Remove these changes from this PR and move them to separate pull requests with
their own linked issues: (1) the atomic SKILL.md write path in createSkill() and
updateSkillModes(), including exclusive temp files, rename, cleanup, disposal
tracking, and permission-bit preservation; (2) the stale-sidecar sweep at

serialization, lineWidth serialization, the settings fallback, the diagnostics
panel and its i18n keys, and their tests.
- Regression Evidence:
In the create rename-failure test, assert that `mockRmdir` receives
`p(GLOBAL_ROO_DIR, "skills", "rename-fails")` and that `mockRm` was not called.
Keep the existing error, temporary-file, and active-file assertions.
- Security Boundaries:
Pin the validated root and parent directories with trusted handles and publish
relative to those handles. Create the staged file with restrictive permissions
from the start, then apply the target permissions before publication.
- Persistence Integrity:
Protect the full read-modify-write operation with the directory lock. Also
detect or prevent concurrent external edits before publishing, and report a
conflict instead of overwriting them.
- Lifecycle Resource Cleanup:
Retry cleanup after skipped sidecars become stale. Preserve protection for
active writes in other processes, and dispose of any cleanup timer or task.

Triage of this pull request at head 9e287f60635228e9ce8042010785bab4b0e9eca7, branch fix/skill-frontmatter-yaml-859 on the fork, base main pinned at 5319fe91fb0caf4aa4ec66aac68fa03744ebbc23. Every number below is from a read taken 2026-11-09 16:16Z-16:20Z; the clock is GitHub's own Date header (first read Mon, 09 Nov 2026 16:16:24 GMT) and git dates are quoted with their own offsets.
Required contexts. All six required arms are completed/success at this head: check-translations 128832122802, compile 128832122916, e2e-mock 128832122209, knip 128832122595, platform-unit-test (ubuntu-latest) 128832122884, platform-unit-test (windows-latest) 128832122985. The register comes from /commits/9e287f606352…/check-runs, which answers 200 with total_count 22 over one page, 20 distinct check names, newest run per name. (/pulls/1321/check-runs?head_sha= answers 404 and is the wrong endpoint, not an absence of checks.) Of the advisory legs every one is completed/success — including mutation-diff 128832122277, which carries 8 warning annotations and a note that the extension mutation run exceeded 12 minutes — except webview-visual 128832123252 completed/failure. Advisory legs do not gate a merge, and the review-state workflow scopes its labels to the required checks only (.github/workflows/label-pr-review-state.yml reads required_status_checks off the branch ruleset and scopes to check.integrationId === null), so this failure is not what keeps the label where it is.
The one red leg, and what its fix needs. Its annotation is exact: Expected an image 488px by 620px, received 488px by 622px. 13760 pixels (ratio 0.05 of all image pixels) are different, snapshot skills-settings-diagnostics.png, which is in the tree as blob 105d252b4bb6 at 30,182 bytes against the test webview-ui/src/components/settings/__tests__/SkillsSettings.visual.tsx blob 27330ab8d768, 829 bytes. A 2 px height with a 5% pixel delta is a baseline recorded on a different renderer than the one CI runs, which is why the fix is a baseline re-record on the runner image CI uses and not a source edit; a Windows-local render cannot stand in for that proof, and the test and its snapshot are test paths, so they charge 0 of the 273 counted executable lines either way.
Main drift, measured rather than assumed.git merge-base e487cd7b2a49… 9e287f606352… is 5319fe91fb0caf4aa4ec66aac68fa03744ebbc23, which is the same commit the pull request's base is pinned at: main is 3 commits ahead of the branch and the branch is 4,374 commits ahead of that merge base. Main's 3 commits change 14 paths; this pull request touches 56 paths; the intersection is 0 paths, measured by diffing both ranges and intersecting the name lists. So the red advisory above sits in no file main also moved, and merging main would re-run 21 legs without changing that leg's outcome.
The automated review pass is finished even though its progress record is not. Check run 128835896696 (CodeRabbit, output title "Review in progress") still reports in_progress with started_at 2026-11-08T19:25:34Z and no completion, while four independent reads say the pass landed: the review event CHANGES_REQUESTED was submitted at 2026-11-08T19:34:29Z, the newest review comment on this pull request is 4507514975 at 19:34:27Z, the CodeRabbit commit status on this head is success at 19:34:41Z (status id 58375840547), and Zoo Code / reconcile PR review state (1321) 128838329239 finished success at 19:35:38Z. The progress record was never closed; the review it was tracking exists. The legacy Zoo Code / PR review gate status on this head is pending (status id 58375870779) and is advisory by the same workflow's own design.
Threads.reviewThreads paginated with first: 50 and after: $cur: 33 threads on 1 page (totalCount 33, hasNextPage false), and all 33 return a rootComment database id, which is what proves the grouping matched real comments before any count is quoted. 32 resolved, 1 open; 18 marked outdated and none of those is open. Resolutions: 17 by this account, 15 by coderabbitai[bot]. Opened by author: 32 by coderabbitai, 1 by edelauna. The open row is 4507514975 on src/extension/api.ts:313, filed 2026-11-08T19:34:27Z, Minor / Functional Correctness / Low value, and it is answered in its own thread.
Review state, which is what actually blocks. GraphQL reviewDecision is CHANGES_REQUESTED and mergeStateStatus is BLOCKED with all six required contexts green, and the only human review in the 61 review records is edelaunaCHANGES_REQUESTED 2026-10-20T04:34:10Z (review 5580793451); the other 60 records are coderabbitai[bot] (45) and this account (15), the latter's latest being COMMENTED 2026-11-05T16:36:50Z. That human change-request asks one thing — a description long enough to prove the description: line stays unfolded — and the answer landed in commit c26661b4448f240e15c1859e01a740d4817acfca, test(skills): pin single-line descriptions through the yaml round-trip, authored and committed Thu Oct 22 02:43:19 2026 +0800, which is an ancestor of this head; src/services/skills/__tests__/SkillsManager.spec.ts moved from blob f3c1c01a0829a7505523392ab6893a296175c5a2 there to 28b7a26b0746a38c8d7a30afadb89859e7036a4b at this head, and thread 4321491053 was resolved by this account on 2026-10-21. Per the workflow's own rule for maintainer blockers (label-pr-review-state.yml, the block beginning at the comment about a human maintainer's change request blocking the queue until that reviewer acts), a maintainer's change request clears on a newer review from that reviewer, a review re-request, or a GitHub dismissal — not on a push and not on a COMMENTED. So the pull request is awaiting-author because of a reviewer state whose content demand was met 19 days ago, and the merge additionally needs one approval plus a code-owner approval from the taltas/JamesRobert20/navedmerchant/edelauna wildcard.
No push in this pass, and why. The required arms are already green, so a push has no red required arm to clear; the only red is an advisory leg whose fix is a baseline re-record that this environment cannot produce; main moved no path this pull request touches, so a merge cannot clear it either; and a content commit would re-run the 21 legs and buy a fresh automated review pass, whose dismiss_stale_reviews_on_push behaviour cannot be relied on to dismiss a code owner's change request. Nothing was resolved, no label changed, no review requested, and the label read after these posts is unchanged.
One error in this pass, printed where it happened. My first GraphQL read of this pull request asked for latestCommit and then for resolvedAt on PullRequestReviewThread; neither field exists on that type, and both attempts failed with undefinedField before returning anything — the per-thread resolution table above comes from the retry that asked only for resolvedBy { login }.
Heard, and labelled as such: the earlier note in thread 4461202048 (2026-11-03T22:27:36Z) that this baseline must come from test:visual:docker:update on the image CI uses, and that a local Docker attempt failed here for worktree node_modules reasons — that is my own earlier record, not something re-measured in this pass.
Read the walkthrough's pre-merge checklist (comment 5365478111, updated_at 2026-11-08T19:34:35Z, 26,238 B, rewritten in place) and verified each row against head 9e287f606352 and blob d1c46a1235fbe79e887d7b173f841bbbe7f4f599 of src/services/skills/SkillsManager.ts, which is 1,469 lines. The checklist prints 3 errors and 2 warnings; here is what each row corresponds to in the code at this head, with the line numbers the row cites read at that head.
Security Boundaries (error) - real, partially mitigated, not closed. The row cites 1264-1270 and 789-804. At the head, 1264 is const targetPath = await fs.realpath(skill.path), 1265await this.assertTargetWithinSkillsRoots(targetPath, source), and 1269-1270 re-resolve and re-assert the target inside the callback passed to writeSkillFileAtomically. Inside that helper the callback is invoked at :780 (await validateTarget?.(filePath)), immediately before the mode-preserving fs.stat at :789 and the fs.rename(temporaryPath, filePath) at :804. So the publish path does re-check the resolved target just before renaming, and the file's own comment at :778-779 states the residual window: "the target (or an ancestor) can change between the caller's resolution and this publish". The row's remedy - pin the validated root and parent with trusted handles and publish relative to those handles - is a stronger guarantee than path re-resolution provides, and it is a code change rather than a sentence.
Persistence Integrity (error) - real.updateSkillModes() reads the file at :1242 (const fileContent = await fs.readFile(skill.path, "utf-8")) and only enters the per-directory lock later, at :1266 when writeSkillFileAtomically takes withDirectoryLock at :763. The read is therefore outside the lock that serialises the publish, so the read-modify-write is not fully serialised and a concurrent external edit between :1242 and the rename is not detected. Closing it means moving the read inside the same lock (and reporting a conflict), which is a code change.
Out of Scope Changes (error) - a scope demand, not a measurement. The row asks that the atomic SKILL.md write path in createSkill() and updateSkillModes() be removed from this pull and moved to separate pulls with their own linked issues, because the whole-PR summary shows changes that do not implement #859 and are not described in the current description. That path is not incidental: it is what :757-812 and the two call sites at :903 and :1266 implement, and the tests that exist for it were written against it. Clearing this row is either an author act (split the write path out) or a reviewer act (the checklist carries an override-pre-merge-checks box marked "Ignore (reviewers only)").
Regression Evidence (warning, optional) - test-only, and it prices at zero counted executable lines. The row cites 902-908, where createSkill removes its own newly created directory with fs.rmdir(skillDir) when writeSkillFileAtomically fails. It asks the create rename-failure test to assert that mockRmdir receives the expected path and that mockRm was not called. That is an assertion added to an existing test file.
Lifecycle Resource Cleanup (warning, optional) - real, measured in the file.initialize() memoises its own run (:131-133) and calls sweepStaleSkillTempFiles() once, at :137; the sweep skips any sidecar newer than SKILL_TEMP_SIDECAR_STALE_MS = 10 * 60 * 1000 (:98, applied at :184) and nothing in initialize() schedules a later pass - the only timer-free paths are dispose(), which removes tracked sidecars at :1454. So a sidecar skipped as "too fresh" is not revisited for the rest of that host's life. The row's remedy (retry once skipped sidecars become stale, dispose the timer) is a code change.
The walkthrough's coverage annotation is stamped sourceCommitId and coveredCommitId both 9e287f60635228e9ce8042010785bab4b0e9eca7, kind reviewed, and reads: "The diagnostics visual test still fails against its committed baseline and should be corrected before merging. Smaller remaining concerns are missing coverage for permission-read failures and mutable diagnostic results that can alter later API responses." That matches the one red leg in the check runs, webview-visual job 128832123252, annotated Expected an image 488px by 620px, received 488px by 622px. 13760 pixels (ratio 0.05 of all image pixels) are different; the attempt to re-record that baseline today stopped before regenerating anything, because the container cannot resolve this worktree's webview dependencies (webview-ui/node_modules/react is a symlink whose stored target is a Windows absolute path into a different worktree's pnpm store, which a Linux container cannot follow even with the containing drive mounted), and the CI image is digest-pinned to mcr.microsoft.com/playwright:v1.62.1-noble@sha256:dcc5531e97840b9b5e794f2814476b21571c5124a3fca2267d73041f56e7580e. A baseline rendered on a different image or a different platform is not a substitute for this one.
This note records measurements and states which of the five rows cannot be answered by measurement; it asks nothing of anyone. Written against head 9e287f606352 at 2026-11-09T17:13Z with git show 9e287f606352:src/services/skills/SkillsManager.ts (1,469 lines) and GET /repos/Zoo-Code-Org/Zoo-Code/issues/1321/comments?per_page=100&sort=created&direction=asc (66 records, page 2 empty), reading comment 5365478111 out of that list because GET /repos/.../issues/1321/comments/5365478111 answers 404.
updateSkillModes read SKILL.md outside the directory queue that guards its rename, so a
stale-sidecar sweep or a second update could land between that read and the publish, and
the older value won the race. writeSkillFileAtomically now takes a content producer and
runs it inside the lock, and updateSkillModes passes the read, the frontmatter edit and
the serialisation as that producer, so the read-modify-write occupies one queue slot.
The create rename-failure test now asserts the rollback removed the skill directory with
rmdir and never reached the recursive rm. The stale-sidecar sweep, which skips files too
fresh to touch because another process may still be writing them, now schedules one
unref'd retry after the staleness window and dispose() cancels it, so an abandoned
sidecar no longer waits for the next launch while live writes stay protected.

Review comments at @src/services/skills/__tests__/SkillsManager.spec.ts:
- Around line 2720-2724: Update the test around mockReadFile to return the
original content on the first read and edited content after the rename, then
assert that the second staged payload preserves the edited body or non-mode
field. Keep the existing read-order checks while ensuring the test detects when
the queued read result is discarded.
Review comments at @src/services/skills/SkillsManager.ts:
- Around line 1271-1272: Update the queued read in the skill update flow to read
from targetPath, and before proceeding reject the update if skill.path no longer
resolves to targetPath. Preserve the existing update behavior when the paths
still match.
- Around line 148-150: Update sweepStaleSkillTempFiles so cleanup coordinates
with writers across processes and does not delete a sidecar while an update is
staged or its writer is paused; establish and use a cross-process coordination
mechanism before deleting each sidecar, preserving the writer’s ability to
resume and rename it.
- Around line 148-152: Add timer tests around the stale-sidecar retry in
SkillsManager that verify a fresh sidecar is removed when the scheduled sweep
runs and that disposing the manager cancels the pending retry. Ensure the tests
fail if the callback does nothing or disposal no longer clears the timer.
---
Failed pre-merge checks:
- Out of Scope Changes check:
Remove the unrelated stale-sidecar lifecycle, cross-manager locking,
symlink/realpath containment, rollback, and disposal-cleanup features and their
tests. Remove the `outside_skills_root` messages and test, unrelated settings
translations, and `write-delay-labels` test. Keep the parse diagnostics,
user-visible diagnostics flow, and YAML serialization changes and their relevant
tests.
- Regression Evidence:
Add a test that makes the publish-time target `stat` fail with `EACCES` or `EIO`
and checks error propagation, temporary-file cleanup, and no rename. Add
timer-based tests that verify a fresh sidecar is swept after the retry and that
disposal cancels the retry.
- Security Boundaries:
Create the staged file with restrictive permissions from the start. Apply the
target permissions before publication. Pin the validated root and parent
directories with trusted handles, and publish relative to those handles.
- Persistence Integrity:
Detect and prevent external edits during mode updates, and report a conflict
instead of overwriting them. Make skill creation an atomic create-if-absent
operation so a queued create cannot replace an existing file.
- Lifecycle Resource Cleanup:
Make cleanup cover every supported resolved target and sidecar name. Revisit
sidecars that are still fresh or appear after initialization. Protect active
writes in other processes, and cancel cleanup timers or tasks on disposal.

Protect live sidecars during the delayed sweep.
If another extension host pauses after staging an update, the delayed sweep can delete its sidecar after ten minutes. The resumed rename then fails, and the update is not saved. Coordinate cleanup with writers across processes before deleting sidecars.

Update sweepStaleSkillTempFiles so cleanup coordinates with writers across
processes and does not delete a sidecar while an update is staged or its writer
is paused; establish and use a cross-process coordination mechanism before
deleting each sidecar, preserving the writer’s ability to resume and rename it.

Answering with what the code does rather than changing it, because what the row asks for is a cross-process coordination mechanism and that is a design decision for the maintainers, not a line edit I can make inside this pull request.
Measured from the file at 9714d1f, which my commit does not change in this area. withDirectoryLock serialises through a static Map keyed by realpath, so it coordinates writers inside one process only. The strings proper-lockfile and lockfile do not occur anywhere in src/services/skills/SkillsManager.ts: 0 occurrences, so there is no inter-process lock on either side of the sweep. sweepStaleSkillTempFiles skips a matching sidecar whose mtime is younger than SKILL_TEMP_SIDECAR_STALE_MS, defined at line 98 as 10 * 60 * 1000. The one delayed retry fires after that window, is unref'd, and is cancelled by a disposable pushed at line 152. dispose() unlinks only the sidecars this instance tracked in activeTempFiles, which is why a host that stops between staging and rename needs the sweep at all.
So the exposure you describe is real and this is its exact shape: a writer that stages a sidecar and then pauses for more than ten minutes before its rename loses the sidecar to another process's sweep, and its resumed rename then fails and the update is not saved. Inside a process the queue prevents it; across processes the only guard is elapsed time. Closing it needs something that outlives the process - a lockfile next to the sidecar, a lease the writer renews, or recording the staged write so a sweep can see a live owner. Each of those changes what a crashed host leaves behind, so I am leaving the choice to you rather than picking one here.
Not resolving this thread and not requesting a re-review.

@easonLiangWorldedtech Thanks for tracing this. The supplied code supports your analysis: the queue is process-local, so another host can remove a live sidecar after it ages past the threshold.
I understand that cross-process coordination needs a maintainer decision. The finding remains open. Would you like a GitHub follow-up issue for that decision?
Separately, the last saved pre-merge assessment reports blocking scope, security, and persistence checks. Their status on the current revision is unverified; rerun them before merging.

Restating the answer, naming the residual case, recording the status.,,The measurement behind the answer: the queue that orders these operations is withDirectoryLock taken per directory — defined at SkillsManager.ts:737, taken by the sweep at :182, taken by the writer at :775 — and it is process-local. Nothing in the changed path writes a lock file, uses a cross-process primitive, or compares owner identity. So on a second host the same directory is swept under that host's own lease: the freshness test at :194 (Date.now() - stats.mtimeMs < SKILL_TEMP_SIDECAR_STALE_MS, ten minutes per :98) can pass for a sidecar another process staged and has not yet renamed, and the unlink at :195 then removes it. Residual case, stated precisely: a writer that pauses more than ten minutes between staging the sidecar and renaming it can have that sidecar swept by another process. It is outside this box's test surface because every operation in the suite, and every operation the extension performs today, runs in one process.,,Why this is recorded as a design decision and not a defect in the shipped hunk: closing it needs a form of cross-process coordination this file does not currently have any version of — an on-disk lease the sweep must honour, identity comparison before unlinking (stat the staged sidecar and compare against what the writer recorded), or a shorter window that trades away the protection ten minutes give a slow rename. A lease file adds its own failure mode (a stale lease blocks every writer until something reaps it), identity comparison only narrows the window rather than closing it, and shortening it changes semantics for slow filesystems. That is a maintainer call, and I am not making it in this PR.,,On your offer of a follow-up issue: no from me — opening issues is not this lane's authorisation — so the decision stays recorded in this thread for a maintainer to place wherever they want it, and the issue is theirs to open if they want one.,,Heard, not measured: your line that the last saved pre-merge assessment reports blocking scope, security and persistence checks with unverified status on the current revision — that is your saved assessment. What I measured on this revision: GET /commits/9b6dc1a639db/check-runs at 2026-11-09T22:35:35Z reports 17 legs with filter=all and the same 17 with the filter omitted — 5 success, 1 skipped (CodeRabbit, "Review skipped: excluded by label configuration"), 11 in progress (mutation-diff, knip, compile, platform-unit-test on both runners, Build test VSIX, theme-fixtures, e2e-mock, the two visual jobs, Analyze). A mid-run read at that timestamp, so its counts are not a settled fact about the commit. Separately, CHANGES_REQUESTED review 5833291397 at 21:48:27Z carries a 111-byte body — "Pre-merge checks failed. Please resolve the failing checks before merging." — with zero attached comments and sits on the previous revision; recorded, not chased.,,Resolve state at head 9b6dc1a: the row you resolved (thread root 4516247295) reads resolved: true, outdated: true, as does the targetPath row (4516247328). With require_review_thread_resolution false a resolve here is courtesy only, so there was nothing for me to act on, and these two rows stay open exactly as you said you would leave them.

@easonLiangWorldedtech Thanks for documenting the residual case and the design tradeoffs. I understand that you are leaving the coordination decision to maintainers. I will not open a follow-up issue or request a re-review.
Your check-run report is a mid-run snapshot. I have not verified the current checks, approval, or thread status.
The saved pre-merge assessment remains blocking and flags scope, sidecar security, and persistence risks. Before merging, rerun those checks and verify the current required checks and review decision.

Test the delayed sweep and its cancellation.
Add timer tests that verify an initially fresh sidecar is removed after the retry and that disposal prevents the scheduled sweep. The current tests would still pass if the retry callback did nothing or disposal stopped clearing its timer.

Fixed in 17b2689, test only. Two tests added under the stale-sidecar sweep section. "revisits fresh sidecars once the delayed sweep fires" counts sweep invocations through the instance method and pins both halves the row describes: after initialize() there is one sweep, advancing to 9 min 59.999 s still leaves one, advancing one more millisecond makes two. "cancels the delayed sweep when disposal lands inside the window" disposes inside the window and advances past it, and asserts the count stays one.
Controls, both run, matching the two failures the row names: an empty retry callback makes the first test fail, and registering a disposable that does not clear the timer makes the second test fail; restoring each makes its test pass. SKILL_TEMP_SIDECAR_STALE_MS is module-private, so the ten-minute window is written in the tests rather than exported for them.

@easonLiangWorldedtech Thanks for the test details and the reported mutation checks. The tests, as described, cover retry timing and cancellation but do not verify that the delayed sweep removes a sidecar.

Verification added at 9b6dc1a — one commit on top of 17b2689, PR head now 9b6dc1a.,,The test that only counted sweep invocations now proves the removal. In revisits fresh sidecars once the delayed sweep fires (src/services/skills/__tests__/SkillsManager.spec.ts:4333) the readdir fixture lists .SKILL.md.789.ghi.tmp, mockStat reports mtimeMs: Date.now() - sidecarAgeMs, the counting wrapper delegates to the real sweep body and sets sidecarAgeMs to ten minutes after the first fire, and the assertions require: after initialize(), sweep count 1 and unlinkedSoFar()not containing the path (:4374); after advanceTimersByTimeAsync(10 * 60_000 - 1), still no unlink (:4379); after the final millisecond, sweep count 2 and unlinkedSoFar() containing sidecarPath (:4383, "the delayed sweep removes the sidecar the first sweep skipped"). The freshness skip at SkillsManager.ts:194 and the unlink at :195 are both pinned, so the retry the delayed timer exists to perform is what the test now checks.,,Two traps surfaced while writing it, both named in comments inside the test:,- fake timers in this suite do not fake Date, so a fixed planted mtime never ages and the second sweep would skip for the wrong reason — the fixture therefore returns Date.now() - sidecarAgeMs;,- capturing skillsManager["sweepStaleSkillTempFiles"] into a local and calling it unbound loses this, so the delegated call threw inside the sweep and fs.unlink(...).catch(() => {}) swallowed the throw — which is how the test passed before while removing nothing. The wrapper calls originalSweep.call(skillsManager) (:4365) for exactly that reason.,,Numbers: vitest run services/skills/__tests__/SkillsManager.spec.ts (cwd src, node v22.23.4) prints 1 file / 134 tests passed, exit 0. Control — replace the removal statement at SkillsManager.ts:195 with void stalePath and the same command prints 2 failed | 132 passed, exit 1, including expected [] to include '\...\.SKILL.md.789.ghi.tmp'; restore the committed file (SkillsManager.ts unchanged by me, 70a8791b3451081e) and it prints 134/134, exit 0. tsc -p tsconfig.json --noEmit exit 0. eslint --prune-suppressions --max-warnings=0 on this spec exit 0 with src/eslint-suppressions.json byte-identical before and after (30,910 B, 055a26991146ecea, 265 entries / 2,868 suppressed total). A first draft introduced a new any in the unlink-call mapping, which the prune run reported as a third error, so it was rewritten without one instead of raising that file's entry from 2.,,Gate pricing for this commit under the gate's own merge-base semantics: against its first parent 17b2689 — how the gate prices a two-parent head — no package is charged, the change is test-path only. Against base e487cd7b2a49 (read from GET /branches/main) with merge-base 5319fe91fb0c the PR charges package src (the extension package) 282 changed executable lines and webview-ui 37; the deciding package is src at 282, 218 lines under MAX_CHANGED_LINES 500. The 319 across both packages is descriptive, not the gate.,,Thread left open as you agreed; nothing resolved on this PR by me.

Produced by mcr.microsoft.com/playwright:v1.64.1-noble (digest sha256:47b510dd9230bf0b9bfc9b20102241e577ea7a99334ab4c3ca19f19770e9b8ea) running the repo's own playwright-ct.config.ts with --workers=2 --update-snapshots from a tree with its own frozen-lockfile install; the run rewrote exactly this one file.
The result is byte-identical to the actual image CI itself uploaded under artifact webview-visual-regression for run 42667399579 (44846 B, 488x622); the committed baseline it replaces is the expected image CI captured (30182 B, 488x620). A host-side run of the same command on Windows passes the old baseline, so the host is not a valid producer of this snapshot - only the pinned image reproduces the 488x622 rendering CI sees.
The change costs the diff-size gate nothing: scripts/stryker-diff.mjs packageForPath returns undefined for a .png path, so buildManifest includes no package for it and the charged executable-line count stays 308.
… and pin the sweep retry
The update path resolved skill.path once and then read through skill.path inside the
directory queue, so a container symlink retargeted while an update waited composed the new
target's contents and renamed them over the file the update was asked for. The queued producer
now reads targetPath, and the pre-rename validation rejects the update when the path the caller
named no longer resolves to it.
Tests: pin the retarget window end to end, give the queued double-update test two distinguishable
reads so a discarded read cannot pass, and add timer tests for the delayed stale-sidecar sweep and
for disposal cancelling it.

The retry-timing test counted sweep invocations and swallowed the sweep body, so it proved the

the real sweep with the manager instance preserved, the fixture ages the sidecar between the two
fires, and the assertions require the first sweep to leave it alone and the delayed sweep to
unlink it.

Mutation report at head 9b6dc1a: dispositions for all ten blocking rows
Read window. I re-read the gate comment 6663025908 once, at 2026-11-09T23:00:02Z, after the mutation-diff leg (check-run 129487371127) had completed: completed/success with 8 annotations, read at 22:59:43Z with filter=all. The comment was last updated 2026-11-09T22:52:11Z, its body is 5,052 bytes and its marker reads head:9b6dc1a639dba69c79bb2aabb44ba607db763ebd blocking:10 advisories:1. After normalising the marker sha, this body and the 17b2689 copy differ in four byte windows only: the "Report for PR head" short sha, and the reproduce line's --head value (c67b8d5 becomes f48af40). All ten survivor rows are identical in both copies, which is what a spec-only commit should produce.
Which package decides. The gate prices each package separately, so: deciding package extension, 282 changed executable lines against the 500-line cap (218 lines of headroom), reporting 0 valid / 0 killed / 0 timeout / 0 survived / 0 no-coverage with result "Advisory incomplete" and the advisory "extension mutation run exceeded 12 minutes. Split the PR or obtain a maintainer-reviewed narrow exclusion." That package is unmeasured, not clean. webview-ui is measured: 37 changed executable lines, 31 valid, 21 killed, 0 timeout, 10 survived, 0 no-coverage, result "Advisory findings". The ten rows below are its whole blocking set; webview-ui is not the deciding package and its 37 lines are not what prices this PR.
Baselines at this head (interpreter node v22.23.4, cwd webview-ui, entry webview-ui/node_modules/vitest/vitest.mjs): SkillsSettings.spec.tsx printed "Tests 22 passed (22)", exit 0; ExtensionStateContext.spec.tsx printed "Tests 42 passed (42)", exit 0.
Replay against the shipped suites, one mutant at a time, source restored after each run:
40 array: the mutated file is byte-identical to the original (sha256 4154162d9c72d047 before and after).
Controls I wrote, ran and then deleted (scratch files, never committed, worktree still clean):
u31-exact-control.spec.tsx renders SkillsSettings with the same mocks and asserts each diagnostics row by exact text instead of substring: clean tree "Tests 1 passed (1)" exit 0; under 249-outer-template exit 1 (1 failed); under 249-empty-string exit 1; under 250 exit 1; under 252 exit 0 (1 passed).
u31-seed-control.spec.tsx mounts the real provider with skills and skillDiagnostics in initialState, plus a second case with an empty initialState: clean tree "Tests 2 passed (2)" exit 0; under 391-arrow exit 1 (2 failed); under 391-logical exit 1 (2 failed); under 391-array exit 1 (1 failed | 1 passed, the empty-default case); the three 393 rows behave identically to their 391 twins.
Both controls pass on the unmutated tree, so the failures below are the mutants', not the harness's.
Dispositions. No Stryker directive is added anywhere in this PR.
SkillsSettings.tsx:40 ArrayDeclaration to "[]" - equivalent by construction: the array literal being replaced already is "[]", so the mutant reproduces the file byte for byte.
SkillsSettings.tsx:249 StringLiteral to "Stryker was here!" - the branch taken when a diagnostic has a line and no column. Not equivalent: it appends text the shipped spec cannot see, because SkillsSettings.spec.tsx:252 asserts with toHaveTextContent, a substring match. Killed by an exact-text assertion at that same position, which my control supplies.
SkillsSettings.tsx:250 StringLiteral to "Stryker was here!" - the branch taken when a diagnostic has no line. Same mechanism, invisible to the substring assertion at SkillsSettings.spec.tsx:250, and killed by the same class of exact-text assertion.
SkillsSettings.tsx:252 StringLiteral to the empty template - equivalent for everything this PR's tested flows can observe: that literal is React's key for every diagnostics row; the rendered text is unchanged, keys are not exposed to jsdom assertions, and neither suite reconciles a changing diagnostics list. It survives the shipped suite and it survives my exact-text control. Under the mutation-gate protocol a genuinely equivalent mutant is a maintainer's narrow-exclusion call, not a suppression, so I add no directive and I am not going to add a test whose only job is to restate a React key.
ExtensionStateContext.tsx:391 ArrowFunction to "() => undefined" - not equivalent: a webview mounted with skills in its initial state would get undefined. Killed by the seed control, both cases. The shipped suite misses it because its initialState test (ExtensionStateContext.spec.tsx:824-866) seeds seven other fields and never seeds skills or skillDiagnostics.
ExtensionStateContext.tsx:391 LogicalOperator to "initialState?.skills && []" - not equivalent, and strictly worse than the original: with a truthy seed it throws the seeded array away and yields an empty one. Killed by the seed control, both cases.
ExtensionStateContext.tsx:391 ArrayDeclaration to a one-element array - not equivalent: the default for a provider mounted without skills becomes a list holding one bogus skill. Killed by the seed control's empty-initialState case only, which is precisely the path the mutant changes.
ExtensionStateContext.tsx:393 ArrowFunction to "() => undefined" (skillDiagnostics) - same mechanism as row 5, killed by the seed control, both cases.
ExtensionStateContext.tsx:393 LogicalOperator to "initialState?.skillDiagnostics && []" - same mechanism as row 6, killed by the seed control, both cases.
ExtensionStateContext.tsx:393 ArrayDeclaration to a one-element array - same mechanism as row 7, killed by the seed control's empty-initialState case.
Width. Every test named above lives under a tests/ directory, and the gate leaves those paths unpriced, so writing them does not move the deciding 282. Nothing here needs a push: I pushed nothing in this unit and wt-r130-1321 is clean against 9b6dc1a. The extension package's own problem is width - a 12-minute overrun on 282 changed executable lines - and the remedy the gate itself names is a split or a maintainer-reviewed narrow exclusion, not killing mutants.
Unmeasured versus measured, across every gate report I have saved (scan of 6,091 files, 273,350,420 bytes under .tmp-cr-audit, node_modules and .git skipped). I print only numbers my own greps returned.
"exceeded 12 minutes": 14 hits in 14 files. Every one of them is this 1321 report, my own earlier writing about it, or a copy of my ledger, so within everything I have saved 1321 is the only PR unmeasured for wall clock.
"generated N mutants in preflight (limit 400)": 12 lines - 420 on 1311 (report comment 6639983485), 425 on 2385, 445 on 1930, 510 and 512 on 1911, and 512 and 535 in my saved u13 rows. Those packages are unmeasured for the mutant cap.
Every saved report whose marker says blocking:0 pairs it, in the same body, with a package row of 0 valid mutants: 1311 extension 449 lines / 0 valid, 2385 extension 448 / 0, 1911 extension 496 / 0, 1930 extension 494 / 0, and 1321 extension 282 / 0. Not one of those zero-blocking readings is a clean bill of health; each is an unmeasured package.
Measured packages all carry blocking rows: 1910 prints 347 lines / 318 valid / 57 survived / 2 uncovered; 2383 prints 386 / 372 valid / 78 survived / 8 uncovered; 1929 prints 368 / 349 valid with 56 survived / 5 uncovered in one row and 54 survived / 5 uncovered in another, under markers reading 61 and 59; PR 70 prints 339 / 279 valid / 34 survived / 38 uncovered under a marker reading 72; PR 71 prints 38 / 17 valid twice, 7 survived / 1 uncovered and 6 survived / 1 uncovered, under markers reading 8 and 7; 2393 carries 26 blocking by its marker. Where a saved file holds several markers I quote its rows and its markers without pairing them; the pairings above are only the ones where a file carries exactly one marker and one package row.
In everything I have saved, no PR is both measured and clean.
I also scanned "Advisory incomplete" (294 hits in 121 files) and "Advisory findings" (294 hits in 114 files); those counts are dominated by CI job-log self-test subtest names, not PR verdicts, so I draw no verdict counts from them.
Open human verdict: review 5580793451, from edelauna, state CHANGES_REQUESTED, submitted 2026-10-20T04:34:10Z, body 0 bytes. It is still CHANGES_REQUESTED at head 9b6dc1a. My own review read at 2026-11-09T23:07:04Z (GET /pulls/1321/reviews?per_page=100, page 1 then page 2: 86 rows then 0, so the read is complete) splits those 86 rows as COMMENTED 57, CHANGES_REQUESTED 25, DISMISSED 4. Of the 25 change requests, 24 are coderabbitai[bot] and one is edelauna's - one human verdict, not twenty-five.
Bot rows are answered or fixed. My two thread replies, both verified by GET /pulls/comments/ at 23:07:33Z (status 200): 4518837603, 3,223 bytes, in reply to 4516247317 on src/services/skills/SkillsManager.ts:152; 4518838207, 3,330 bytes, in reply to 4516247309 on SkillsManager.ts:150. My thread census of 22:41:30Z stood at 37 threads, 35 resolved, 2 unresolved, 21 outdated.
CI at 22:59:43Z, filter=all: 35 legs, total_count 35 (pagination complete), 34 completed/success, 1 completed/skipped (CodeRabbit, "Review skipped: excluded by label configuration"), 0 in progress. mutation-diff completed/success with 8 annotations; codecov/patch success at 97.71% of diff hit and webview-patch success at 100.00%. All six contexts the main ruleset requires are completed/success at this head; that list is from my own read of ruleset 15494382 "Protect Main" at 23:07:04Z with strict_required_status_checks_policy false: check-translations, platform-unit-test (ubuntu-latest), platform-unit-test (windows-latest), compile, knip, e2e-mock. REST says mergeable true and mergeable_state blocked.
Labels as of 22:59:43Z read ["awaiting-author"] (earlier in this round the same endpoint returned awaiting-coderabbit plus coderabbit-review-active). I issued no label mutation, no review mutation, no resolve and no review re-request in this unit. The label claims the author owes something; what is actually open is a human change request that this token cannot dismiss, cannot approve and cannot re-request, and a push would not clear it - this unit pushed nothing, and I am not treating dismiss_stale_reviews_on_push as a lever against another person's verdict.
… in initialState
Strengthens the SkillsSettings diagnostics assertions to exact element text so the StringLiteral
mutants CI reports at SkillsSettings.tsx:249 and :250 no longer survive, and seeds
skills and skillDiagnostics through initialState in ExtensionStateContext.spec.tsx so
the ArrowFunction, LogicalOperator and ArrayDeclaration mutants at :391 and :393 fail.
Spec-only: no Stryker directive, no source change.
What the next mutation report on this PR will clear and what it will not
The push landed as 6b59564, parent 9b6dc1a. Two files changed, 57 insertions and 2 deletions, and both of them are specs: webview-ui/src/components/settings/tests/SkillsSettings.spec.tsx and webview-ui/src/context/tests/ExtensionStateContext.spec.tsx. No source file changed and no Stryker directive was added.
Priced before writing, with the gate's own selectFromGit at 23:22:30Z against base e487cd7 (merge base 5319fe9): extension 282 changed executable lines, webview 37, identical to the head I pushed from. Feeding the two spec paths through buildManifest on their own returns 0 package entries, because packageForPath returns nothing for a path carrying /tests/ - gate line 85 is that exclusion list and both files are in it. So this push charges no lines: the deciding figure on this PR is still the extension package at 282 of 500 with 218 of headroom, and webview's 37 is not what prices it.
What the specs now do, with the command that shows the suites still pass. Interpreter C:/work/Zoo-Code-fork/.tmp-node22/node_modules/node/bin/node.exe v22.23.4, cwd webview-ui, entry webview-ui/node_modules/vitest/vitest.mjs. Before the edits the shipped suites printed Tests 22 passed (22) for SkillsSettings.spec.tsx and Tests 42 passed (42) for ExtensionStateContext.spec.tsx. After them the same two commands print Tests 22 passed (22) and Tests 44 passed (44), both exit 0. In the same directory tsc --noEmit exits 0 with no output, and eslint on the two spec files exits 0 with no output, both with and without --prune-suppressions. SkillsSettings.spec.tsx now asserts the exact text of each diagnostics row's location span rather than a substring match, and the case set gained a third row carrying both a line and a column so the inner column template is pinned too. ExtensionStateContext.spec.tsx now seeds skills and skillDiagnostics through initialState, and separately asserts both come back as empty arrays when initialState omits them.
Each of the ten reported mutants re-run against the suites as they now stand, one at a time, source restored after every run:
SkillsSettings.tsx:40, ArrayDeclaration to []: the mutated file is byte-identical to the original, sha256_16 4154162d9c72d047 on both sides, and the suite prints Tests 22 passed (22) at exit 0.
SkillsSettings.tsx:249, StringLiteral replacing the outer location template: Tests 2 failed | 20 passed (22) at exit 1. The same replacement applied to the inner column template on that line: Tests 2 failed | 20 passed (22) at exit 1.
SkillsSettings.tsx:250, StringLiteral replacing the empty fallback: Tests 1 failed | 21 passed (22) at exit 1.
ExtensionStateContext.tsx:391 and :393, ArrowFunction to () => undefined: each prints Tests 2 failed | 42 passed (44) at exit 1.
ExtensionStateContext.tsx:391 and :393, LogicalOperator to the form the report names, "initialState?.skills && []" and its twin: each prints Tests 2 failed | 42 passed (44) at exit 1.
ExtensionStateContext.tsx:391 and :393, ArrayDeclaration to the report's "["Stryker was here"]": each prints Tests 1 failed | 43 passed (44) at exit 1, failing the empty-initialState case, which is the case that fallback changes.
Two of the ten will still read Survived on the next report, and that is expected rather than a failed fix. SkillsSettings.tsx:40 is equivalent by construction: ArrayDeclaration replaces an empty array literal with an empty array literal, so the mutated file is the same bytes as the original and no test can tell them apart. SkillsSettings.tsx:252 is React's key for a diagnostics row; the reported replacement is an empty template literal, the rendered text and the element structure do not change, jsdom exposes no key, and that mutant survives the shipped suite and the strengthened exact-text suite alike. Under the gate's own guidance the route for that one is a narrow, reasoned exclusion with maintainer approval, which is a maintainer call and not mine to make.
CI at the new head, one read with the filter named: GET /repos/Zoo-Code-Org/Zoo-Code/commits/6b5956473168e9459b737724ce838f28f2d91a93/check-runs?per_page=100&filter=all at 23:32:15Z returned 17 legs with total_count 17 on a single page - 1 completed/success, 1 completed/skipped, 5 in_progress (mutation-diff 129515329886, knip, e2e-mock, platform-unit-test windows-latest and the CodeQL analyze leg) and 10 queued, so at that moment no required context had finished on this head and I am not claiming green. The extension advisory - 282 lines and a run that exceeded 12 minutes - will keep printing on this PR whatever the specs do, because that package has never been measured.

The test checks paths by row but checks messages on the alert as a whole. If two messages appear beside the wrong paths, these assertions can still pass. Select the rows by listitem role and compare their complete text in order.
Based on learnings, prefer role queries over markup selectors when a role query works. As per path instructions, tests require “behavior-focused assertions.”

New gate report for head 6b5956473168 read once, and what moved since 9b6dc1a639db
Upstream main read in this same call: 332d30fbb9d8852a61b4512a5ce550e10cf84f24 (2026-11-10T00:23:48Z). Widths below are quoted against that tip.
The read. One read, filter GET /repos/Zoo-Code-Org/Zoo-Code/issues/1321/comments?per_page=100 (issue-comment listing, picking bodies that carry the zoo-code-mutation-report marker), moment 2026-11-10T00:23:26Z→00:23:27Z, page 1 returned 70 comments and exactly one mutation-report body, comment 6663025908, which the gate updates in place. It now carries head:6b5956473168e9459b737724ce838f28f2d91a93 blocking:2 advisories:1, body 3,635 B (sha256-16 996127787e132ce5).

webview-ui/src/context/ExtensionStateContext.tsx no longer appears: its six rows (391 and 393, ArrowFunction / LogicalOperator / ArrayDeclaration) are gone from the report, which prints only Survived and NoCoverage mutants, so their absence means killed. The advisory block is unchanged, word for word: “extension mutation run exceeded 12 minutes. Split the PR or obtain a maintainer-reviewed narrow exclusion.”
The delta, with the deciding package named on every figure — every one of them is the webview package. Surviving/uncovered went 10 → 2 (webview). Killed went 21 → 29 (webview), so eight of the ten named rows died. Valid stayed 31 and changed executable lines stayed 37 (webview) — the push added no new code line for the gate to charge, it only added specs. Timeout stayed 0 (webview). No coverage stayed 0 (webview). The blocking count went 10 → 2 and advisories stayed 1, and the report body shrank 5,052 B → 3,635 B because two per-file tables are gone. Nothing in these figures comes from the extension package: its row prints 0 valid, 0 killed, 0 survived because its run never completed, so extension mutation behaviour is unmeasured, not clean.
Forecast check. Comment 6754372427 forecast eight of the ten dying and two surviving, naming SkillsSettings.tsx:40 and SkillsSettings.tsx:252. The new report prints exactly those two rows and nothing else, so the forecast is confirmed rather than corrected — the survivor set matches by name, not just by count.
Two sentences in the first version of this comment are corrected in place rather than left standing: “at exit 1? no: exit 0” superseded — the measured :40 arm prints Tests 22 passed (22) at exit 0; and “my measured arms could not separate” for :252 superseded — no :252 arm was re-run this round, so that row rests on the forecast plus the new report printing it, not on a fresh local measurement. :40 survives because ArrayDeclaration replaces an empty array literal with an empty array literal: the mutated file is byte-identical to the original (sha256-16 4154162d9c72d047 on both sides) and the suite prints Tests 22 passed (22) at exit 0. It is equivalent by construction, so no assertion can reach it. :252 is the empty-template StringLiteral in the same expression. Stated narrowly: this round I re-ran the :249 (both spellings), :250, :391 and :393 arms and did not re-run a :252 arm, so that row rests on the forecast plus the new report printing it, not on a fresh local measurement from me.
The two extension figures, stated as what they are. The extension row still prints 282 changed executable lines against the gate’s 500-line cap, unchanged from the 9b6dc1a639db report, and unchanged because of what the push touched: both files are specs, and the gate’s own path rules give __tests__ paths no charge (packageForPath returns undefined for them, and they are in EXCLUDED_PATH_SEGMENTS), so spec paths add nothing to the executable-line count. The extension 12-minute overrun is still standing whatever the specs do: the mutation-diff job ran 23:32:02Z → 23:49:34Z, which is 17m32s, and the advisory line is identical in both reports. Splitting or a maintainer-reviewed narrow exclusion remains the only route that changes that row.
Arms, read once, filter GET /repos/Zoo-Code-Org/Zoo-Code/commits/6b5956473168e9459b737724ce838f28f2d91a93/check-runs?per_page=100&filter=all at 2026-11-10T00:22:21Z (23 check runs, total_count 23, tally 22 completed/success and 1 completed/skipped). Each context separately, with its own conclusion:
check-translations — check run 129515335371: completed/success, 23:33:19→23:33:55.
platform-unit-test (ubuntu-latest) — check run 129515335406: completed/success, 23:33:37→23:42:02.
platform-unit-test (windows-latest) — check run 129515335732: completed/success, 23:32:10→23:46:45.
compile — check run 129515335419: completed/success, 23:33:35→23:37:55.
knip — check run 129515334808: completed/success, 23:32:06→23:33:28.
e2e-mock — check run 129515329707: completed/success, 23:32:02→23:37:02.
mutation-diff — check run 129515329886: completed/success, 23:32:02→23:49:34 (17m32s), 4 warning annotations. Success means the gate posted an advisory report, not that the mutation pass is clean: the extension leg is incomplete and the webview leg still reports 2 surviving mutants.
CodeRabbit — check run 129523582524: completed/success, 23:50:14→23:59:49. (the run that posted review body)
CodeRabbit — check run 129515359592: completed/skipped, 23:32:04→23:32:04. (the earlier run in the page, skipped)
Of the six contexts the branch ruleset requires, all six report a conclusion on this head: the two named above and compile (completed/success), knip (completed/success), e2e-mock (completed/success), check-translations (completed/success). The two platform-unit-test legs are named platform-unit-test (ubuntu-latest) (completed/success) and platform-unit-test (windows-latest) (completed/success) in the check-run listing, with the matrix value in parentheses.
What is still not measured. Extension mutation behaviour (0 valid because the leg times out), whether the eight newly killed webview rows stay killed on a re-run — answered below at head 504611564b61: all 31 valid webview mutants killed, none surviving — and requestedReviewers, which I did not query. The 2 remaining webview rows are the ones I forecast and the :40 one is provably equivalent, so the open decision on this PR is the extension split-or-exclusion conversation, not more webview assertions.
Delta at head 504611564b61 — both named rows now killed, read from the artifact first, then priced, then read on CI (added in place 2026-11-10T02:41Z)
Row set re-read from the artifact, not from this comment. Artifact 13721721618 (changed-code-mutation-report, 210447 B, sha256/16 9284fe2754dc0338, created 2026-11-09T23:49:25Z, run 42721208263, job 129515329886, four entries: pr-comment.md 2309 B baaf687571fcabac, webview/mutation.json 211822 B 7c286452fea58417, webview/mutation.html 446912 B 3bbe8c02e6b1d9ad, webview/vitest-related.json 628696 B 43773c216019844e). Its pr-comment.md carries head:6b5956473168e9459b737724ce838f28f2d91a93 blocking:2 advisories:1 and the rows quoted above. Counting webview/mutation.json with the gate own counters prints valid 31 / killed 29 / timeout 0 / survived 2 / noCoverage 0 / ignored 0 and two blocking records. Slicing the report column ranges out of the head source confirms the two records are source-position rows, and gives the replacement text: :40 columns 68-89 replace rawSkillDiagnostics]) with [] (ArrayDeclaration, dependency array emptied, 21 bytes removed / 2 added); :252 columns 21-81 replace the template `${diagnostic.path}-${diagnostic.line}-${diagnostic.column}` with `` (StringLiteral, 60 bytes removed / 2 added).
Both arms reproduced in the declaring package. Interpreter C:\work\Zoo-Code-fork\.tmp-node22\node_modules\node\bin\node.exe (v22.23.4), directory C:\work\Zoo-Code-fork\wt-r130-1321\webview-ui, entry node node_modules/vitest/vitest.mjs run src/components/settings/__tests__/SkillsSettings.spec.tsx, env CI=1, VITEST_MAX_THREADS=1. Clean control: Tests 22 passed (22) exit 0. Arm :40 (mutant file sha256/16 8e8dfdc0639e5f07): Tests 22 passed (22) exit 0, no failing test name — it survived the suite that already existed. Arm :252 (mutant sha256/16 4d5e79091dba6cac): Tests 22 passed (22) exit 0, likewise. After each arm the source was rewritten from the captured preimage and git hash-object -w webview-ui/src/components/settings/SkillsSettings.tsx printed 9c250e85149fbb2dfd72ec0e71a31625ce0b9d4c, the committed blob for that head at that path, with git status --porcelain empty. No blob was left moved between arms.
Classification, done before anything was written. Both rows are killable, and the mechanism is stated for each. :40: rendering with skillDiagnostics: [] and then pushing a non-empty list through the mocked extension state and rerendering the same tree shows the warning on clean source and fails on the mutant with Unable to find an accessible element with the role "alert" — the memo frozen at first render never sees the pushed value. :252: with three distinct diagnostics the rendered rows are byte-identical under clean and mutant (three rows, outerHTML lengths 121/121/121 on both, same text in both orders), so nothing about the text changes; what changes is list identity. Tagging each row on first render and reordering the list shows the row now reading broken-4 is the node first created for broken-4 (carried tag 2) on clean source, and the node first created for broken-2 (carried tag 0) under the mutant, because all three rows then carry the same key and React matches them by position; React 18.3.1 also logs 4 duplicate-key errors for the mutant (captured console entries 5, against 1 on clean, the extra one being the same react-i18next warning both sides). The shipped assertions name those visible consequences; no weaker assertion was written to manufacture a kill, and no directive or suppression was added.
Where the assertions went, and what ran.webview-ui/src/components/settings/__tests__/SkillsSettings.spec.tsx — the spec that owns the behaviour, package-local per AGENTS.md, with no source change: SkillsSettings.tsx is the same blob 9c250e85149fbb2dfd72ec0e71a31625ce0b9d4c at the new head. The spec went 22 to 24 it blocks and 16401 to 19609 bytes, committed blob 4452155988164676a1bdcc8bbe5d3af08beb4d9f (parent 6abaa3d3fa5984f8d6da2b0d5ae1c347aaa83206). Gates run in this span, each named with directory, entry and printed number: whole package node node_modules/vitest/vitest.mjs run in webview-ui → Test Files 188 passed (188), Tests 2498 passed (2498), 48.25 s; node ../node_modules/typescript/bin/tsc --noEmit -p tsconfig.json in webview-ui → exit 0, empty output; node_modules\.bin\eslint.cmd --max-warnings=0 src\components\settings\__tests__\SkillsSettings.spec.tsx in webview-ui → exit 0; node node_modules/prettier/bin/prettier.cjs --check webview-ui/src/components/settings/__tests__/SkillsSettings.spec.tsx at the repo root → exit 0, All matched files use Prettier code style!, and the --write run printed (unchanged). src/eslint-suppressions.json was not touched because no file under src was touched, and webview-ui carries no suppressions file.
Spec paths charge nothing. The gate path rule reads EXCLUDED_PATH_SEGMENTS containing /__tests__/ among the excluded segments, and packageForPath("webview-ui/src/components/settings/__tests__/SkillsSettings.spec.tsx") returns undefined where the same call on webview-ui/src/components/settings/SkillsSettings.tsx returns the webview package entry. Re-pricing at the delivered head lists 2 webview files (SkillsSettings.tsx, ExtensionStateContext.tsx) at 37 changed executable lines; the spec is not among them.
Push, hooks, head, price. One push. Commit 504611564b612b7869ca93e8f529700243031588 on parent 6b5956473168e9459b737724ce838f28f2d91a93, 1 file changed, 95 insertions(+). The pre-commit hook ran lint-staged for the staged file, including pnpm --dir webview-ui exec eslint --max-warnings=0 --no-warn-ignored, and left the file unformatted-forward: worktree, index and committed blob are all 4452155988164676a1bdcc8bbe5d3af08beb4d9f, so the committed blob is what I measured. The pre-push hook printed @roo-code/vscode-webview:check-types: cache miss, executing 688cc4404a100b93, Tasks: 11 successful, 11 total, Cached: 10 cached, 11 total, Time: 5.047s, and the push line printed 6b59564731..504611564b 504611564b612b7869ca93e8f529700243031588 -> fix/skill-frontmatter-yaml-859. HEAD from GET at 02:18:53Z: 504611564b61…, base main / 5319fe91fb0caf4aa4ec66aac68fa03744ebbc23, head repo the fork, mergeable true, mergeable_state blocked, labels awaiting-author, 56 commits, +5249/-528. My own git merge-base for the new head printed 5319fe91fb0caf4aa4ec66aac68fa03744ebbc23 against 5319fe91fb0c…, e487cd7b2a49…, a7157157239a… and 18861b2e3572… — one merge base for all four, so the tip move tonight changes nothing for this PR. selectFromGit at the delivered head printed extension 282 changed executable lines over 3 files and webview 37 over 2 files, against caps of 500 lines and 400 selectors, with no advisories.

CodeRabbit separately: check run 129589529196 completed/success 02:31:30→02:39:23, which is the run that evaluated this head; the push-moment run 129584534546 was completed/skipped. Also on the page and all completed/success: webview-visual 129584520075, extension-host-visual 129584520072, theme-fixtures 129584519668, Build test VSIX 129584516959, dependency-review 129584516807, invisible-chars 129584516540, CodeQL 129585324112, Analyze (javascript-typescript) 129584515313, codecov/patch 129589301210, codecov/patch/webview-patch 129589314575, and the two reconcile rows.
Delivered versus forecast. The leg priced a merge candidate, not the raw head: its own log prints Merge 504611564b612b7869ca93e8f529700243031588 into 18861b2e357203e6cb4d93930aa2ed122b1eecea at checkout e225aa8c4ea6b11ff9731d6208e6075abec7c41a, so the second parent is what CI had for main (lead reports that tip as current — heard, not read by me with my own command in this span). The artifact for this head exists and is dated after the merge, which is what makes it pricing evidence rather than a green row. Its pr-comment.md (1420 B) prints head:504611564b612b7869ca93e8f529700243031588 blocking:0 advisories:1; the table reads webview 37 changed executable lines / 31 valid / 31 killed / 0 timeout / 0 survived / 0 no coverage / Passed, and extension 282 / 0 / 0 / 0 / 0 / 0 / Advisory incomplete. The gate counters over webview/mutation.json (228671 B) print valid 31 / killed 31 / timeout 0 / survived 0 / noCoverage 0 / ignored 0 with blocking: [], and the per-file view shows SkillsSettings.tsx at 19 mutants, all Killed, and ExtensionStateContext.tsx at 12, all Killed. My forecast before the push was 31 valid / 31 killed / 0 surviving / blocking 0 on webview; CI printed those figures, so the difference between forecast and printout is zero on every webview figure. Extension: 282 changed executable lines and 0 valid, unchanged from the 6b5956473168 report, its mutation behaviour unmeasured — which is what I have claimed all along, and the two packages are named separately on every figure above.
Corrected in place. In the paragraph above, the clause “whether the eight newly killed webview rows stay killed on a re-run, and” superseded — measured at this head: all 31 valid webview mutants killed, none surviving. The clause “The 2 remaining webview rows are the ones I forecast and the :40 one is provably …” is superseded by the same measurement: neither row survives at 504611564b61, and the :40 arm was re-run here and died. The line about check run 129515329886 is left standing because it is scoped to head 6b5956473168 and remains true there.
Residual classes, by name. (1) Extension mutation behaviour: 282 changed executable lines, 0 valid, leg incomplete — CI own log prints core Stryker preflight could not start: spawnSync /tmp/stryker-launch-…/stryker ENOENT and Could not write the job summary: EISDIR; I ran no local Stryker preflight on this leg because the gate reads working-tree files, so a merge candidate cannot be priced locally. (2) packages/core/src/value.ts:1 Survived BooleanLiteral, an advisory outside the changed scope. (3) Review state, measured after the push: 87 reviews (COMMENTED 57, DISMISSED 4, CHANGES_REQUESTED 26), 0 APPROVED before and 0 after, so the dismiss-on-push rule had nothing to dismiss on this PR; the human zero-byte CHANGES_REQUESTED 5580793451 (2026-10-20T04:34:10Z) and the CodeRabbit CHANGES_REQUESTED 5834596925 (2026-11-09T23:59:40Z, 11464 B) both still stand, because a push does not clear CHANGES_REQUESTED; 38 review threads, 35 resolved, 21 outdated. I resolved no thread, approved nothing, dismissed nothing and requested no reviewer; the label is still awaiting-author and mergeable_state is still blocked. (4) requestedReviewers still not queried. (5) The routing question owed in comment 6753382426 for the delayed-body test on src/api/providers/utils/error-handler.ts is still open, with the 1311 leg budget measured at 449 of 500.
…rder
Two changed-code survivors in SkillsSettings.tsx had no assertion either way.
The first drops the useMemo dependency on rawSkillDiagnostics, so a diagnostic
that arrives after the view mounts never reaches the warning. The second empties
the <li> key expression, so every row carries the same key and a reordered list
reuses rows by position instead of keeping each row in the element it created.

Failed pre-merge checks:
- Out of Scope Changes check:
Move the stale-sidecar lifecycle, locking, permission, and path-policy changes,
along with unrelated settings translations and the auto-approval label test, to
a separate PR. Keep the YAML parse diagnostics, safe frontmatter serialization,
and related UI translations and tests.
- Regression Evidence:
Add a test that makes the publish-time target `stat` fail with `EACCES` or
`EIO`. Verify that the error propagates, the staged file is removed, and rename
does not occur.
- Security Boundaries:
Create sidecars with restrictive permissions from the start, then apply the
intended mode before publication. Use a race-safe containment mechanism that
prevents or detects ancestor relocation during publication.
- Persistence Integrity:
Protect mode updates against conflicting external edits through publication and
report conflicts. Publish new skills with atomic create-if-absent semantics
instead of replacing an existing file.
- Lifecycle Resource Cleanup:
Clean up abandoned sidecars for all supported resolved target names and
directories. Revisit sidecars that become stale after the retry. Protect active
writes across processes and cancel cleanup tasks on disposal.

Fixes #859
Stacked on #934 — that PR (also fixing #859) adds the structured
SkillDiagnosticcollection (SkillsManager.diagnostics/recordDiagnostic()/getSkillDiagnostics()) and the settings-page diagnostics panel. This PR keeps only the remaining gaps on top of it, so the diff stays minimal if #934 merges first and gets squashed.Problem (remainder after #934)
recordDiagnostic()reports the YAML exception, but the single most common trigger — unescaped double quotes in thedescription— still requires the user to read the raw YAML error and open the file. A targeted hint points at the exact line and the fix.dataobject, and every later parse of the same content silently returns that empty object instead of re-throwing — so a re-scan (watcher event, manual refresh) resurfaces the misleading "missing required 'name' field" symptom and drops the diagnostic.discoverSkills()runs; an older scan finishing after a newer one can append a stale diagnostic for an already-repaired skill.updateSkillModes()rewrites the file with js-yaml's defaultlineWidth: 80, reflowing long plain descriptions into folded block scalars (>-1) on every mode toggle — noisy diffs and format churn.createSkill()had the same exposure.skillDiagnosticsis absent. fix(skills): safely serialize skill frontmatter #934 made the field optional onExtensionState, butSkillsSettingsread it without a fallback — any render without it (and 14 webview tests in the unit-test CI job) crashed withCannot read properties of undefined (reading 'length').settings:skills.diagnostics.*i18n keys were only added toen, which fails thecheck-translationsCI job (all 17 non-English locales).handleUpdateSkillModespostMessage path, the malformed-load branches,updateSkillModes' serialization, and the extension-host → watcher → webview diagnostics flow had no tests.Changes
1. Deterministic frontmatter parsing + unescaped-quote hint (load path) —
src/services/skills/SkillsManager.tsloadSkillMetadata()now parses with explicit empty options (matter(fileContent, {})), bypassing gray-matter's global content cache so a malformed skill reports the same parse error on every scan instead of the first throw being cached as an empty data object.getFrontmatterLine()) extracts the raw top-leveldescription:line with its file line number; the "unescaped double quotes"console.errorhint is only emitted when the parser error's mark is located on that exact line — so a valid quoted description plus an unrelated YAML error elsewhere does not produce a misleading hint.2. Serialized discovery scans —
src/services/skills/SkillsManager.tsdiscoverSkills()is a non-async serializer chaining each run onto adiscoveryChainpromise; the body moved toperformDiscovery(). Overlapping watcher-triggered scans no longer interleave, so an older scan can no longer append a stale diagnostic after a newer scan has observed the repaired file.3. Stable SKILL.md serialization (create/update paths)
createSkill()andupdateSkillModes()now passlineWidth: -1(via a small typed alias, since gray-matter's bundled typings predate its js-yaml dump-options passthrough), keeping long plain values on a single line.yes) are quoted/escaped automatically and always round-trip.4. Settings crash fix —
webview-ui/src/components/settings/SkillsSettings.tsxskillDiagnosticsfalls back to[](same pattern as the existingskillshandling), so the component no longer crashes when the optionalExtensionStatefield is absent. Fixes the 14 webview test failures in the unit-test CI job.5. i18n completion —
webview-ui/src/i18n/locales/*/settings.jsonsettings:skills.diagnostics.title/descriptionto all 17 non-English locales (translated per locale), fixing thecheck-translationsCI failure.6. Tests
SkillsManager.spec.ts(gray-mattervi.mocked with the real parser as default implementation): a serialization regression test (a delayed older scan cannot append stale diagnostics), a gray-matter cache-poisoning regression test (a re-scan of unchanged malformed content must keep reporting the parse failure), the exact issue [Bug] SKILL.md YAML parsing fails silently when description contains unescaped double quotes #859 content (hint + diagnostic logged, misleading "missing required 'name' field" absent), a no-false-hint case with a valid quoted description and an error on another line, a non-Error parse failure exercisingrecordDiagnostic's defensive fallbacks, unterminated frontmatter with a dangling quote (diagnostic recorded, hint absent), create-path round-trip cases, and anupdateSkillModesserialization round-trip case.skillsMessageHandler.spec.ts: newhandleUpdateSkillModessuite (success, empty-slug clearing, omittednewSkillModeSlugs→undefinedwith a non-empty diagnostics list forwarded, missing fields, manager unavailable, rejected promise).ExtensionStateContext.spec.tsx: the skills-message test now asserts the transition that clears stored skills/diagnostics, including a message that omitsskillsentirely.api-get-skills-state.spec.ts: unit coverage for the new test-onlygetSkillsState()accessor (skills + diagnostics returned; empty arrays when the manager is unavailable).apps/vscode-e2e/src/suite/skills-diagnostics.test.ts(new): a real extension-host smoke test of the diagnostics flow — writes a healthy and a malformed (double-quoted description with unescaped inner quotes, the exact [Bug] SKILL.md YAML parsing fails silently when description contains unescaped double quotes #859 failure mode)SKILL.mdinto the workspace's.roo/skillson real disk via atomic sidecar+rename writes so the watcher only observes complete files, waits for the extension host's file watcher to re-discover, asserts the malformed skill is omitted with a diagnostic pointing at it while the healthy skill is unaffected, then repairs the frontmatter and asserts the watcher clears the diagnostic and loads the fixed skill. Teardown removes only the skill directories this suite created.Verification
Merge order
Merge #934 first, then this PR (no rebase needed: this branch already sits on #934's head plus upstream/main).
Updated this round (main refresh): merged upstream main (
