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.

Release Notes
New Features
Skill-loading diagnostics show error details and, when available, line and column locations.
Settings identify affected skill files and explain how to fix their YAML frontmatter.
Skill metadata and loading diagnostics are available through the extension API.
Bug Fixes
Valid skills continue to load when other skills contain errors, and diagnostics refresh as skills change.
Saving skills preserves YAML-sensitive values and avoids leaving partial files after failures.
Skill updates are restricted to their configured skill directories.
Localization
Diagnostic messages and expanded settings text are available in supported languages.
Skill discovery now reports malformed YAML frontmatter as structured diagnostics. The API, extension messages, webview state, and Skills settings expose these diagnostics. Skill creation and mode updates use serialized YAML, path validation, queued operations, and atomic temporary-file publication.
Changes: Skill diagnostics and persistence
Layer / File(s)
Summary
Parse 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 optional line and column data. Creation and mode updates use shared YAML options, serialized directory operations, path checks, and atomic writes. Tests cover diagnostics, cleanup, disposal, concurrency, and round-tripping.
Define and transport diagnostics 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 API and skills messages return diagnostics with skill metadata. Responses use 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 replaces stored skills and diagnostics on skills messages. Skills settings renders localized warnings with paths, messages, and available locations.
Validate and localize diagnostics apps/vscode-e2e/src/suite/skills-diagnostics.test.ts, src/i18n/__tests__/skills-error-locales.spec.ts, src/i18n/locales/*, webview-ui/src/i18n/locales/*
Tests cover malformed and repaired skills, diagnostic rendering, visual layout, required error-message placeholders, and localized settings text.

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.

Full details: Title check
Explanation
The title names the two main changes in the PR: reporting YAML frontmatter parse errors for SKILL.md files, and writing SKILL.md files safely through serialization. The changeset covers both, with diagnostics, a serialized discovery path, atomic writes, and stable frontmatter serialization. The title is 79 characters, which is within a reasonable length, and it uses the conventional fix(skills) prefix. It does not mention every detail, which is acceptable.
Full details: Description check
Explanation
The description links the issue (Fixes #859), and it explains the problem, changes, tests, and verification in detail. It follows the template's main sections in substance, including Related GitHub Issue, Description, and Test Procedure via the Verification section. Several template items are missing or not explicit: the Pre-Submission Checklist is not marked, the Visual Snapshots section is not addressed even though the PR adds a visual test, the Videos section is not addressed, the Documentation Updates section is not answered, and the Get in Touch section is absent. The description also uses some non-STE phrasing, and it depends on stacked PR #934 with a merge-order note. These gaps are non-critical, so the description is mostly complete.
Full details: Linked Issues check
Explanation
[#859] requires either a successful skill load or a clear YAML error that names the cause. It must not report only the misleading missing-'name' message. The supplied summary shows that SkillsManager.loadSkillMetadata() parses with matter(fileContent, {}), which bypasses the gray-matter content cache. A parse failure records a SkillDiagnostic with the YAML reason and line and column. The description hint is logged only when the parser error location is on the description line that contains a double quote. The settings panel reads skillDiagnostics from extension state. Tests cover the exact #859 content, the no-false-hint case, repeated scans, and the extension-host watcher flow. This assessment relies on the supplied summaries and test reports. No repository inspection was run. No unmet coding requirement was found.
Full details: Persistence Integrity
Explanation
No changed persistence path meets the failure condition. writeSkillFileAtomically awaits exclusive sidecar creation, target validation, permission preservation, and same-directory rename (SkillsManager.ts:757-804). Its failure path removes owned temporary files and rethrows the original error (805-816). createSkill and updateSkillModes await the atomic writer and discovery refresh (902-912, 1264-1274). The created-skill cleanup removes only the new empty skill directory on failure (904-908). Skill diagnostics defaults propagate through initial state, skills messages, and the settings consumer (ExtensionStateContext.tsx:391-394, 552-555; SkillsSettings.tsx:38-40).
Full details: Lifecycle Resource Cleanup
Explanation
No changed lifecycle path introduces a concrete listener, watcher, timer, provider, or task leak. SkillsManager.initialize() caches one initialization, checks disposal before discovery and watcher setup, and setupFileWatchers()/watchDirectory() stop creating watchers after disposal. Watchers are disposed in dispose(), including container watchers. Discovery and directory-write queues settle rejected work and prevent queued operations from starting after disposal. Atomic writes track temporary files, clean them on failure, and remove tracked sidecars during disposal. The new E2E test uses the existing waitFor() helper, which clears its timers on success, failure, and timeout.
Full details: Out of Scope Changes check
Explanation
Several changes do not implement [#859]. In SkillsManager.ts, the PR adds atomic SKILL.md writes with exclusive temporary files, stale-sidecar sweeping, per-directory locks across symlink aliases, realpath and containment checks for mode updates, permission-bit preservation, disposal-aware queued writes, and rollback of created skill directories. The outside_skills_root entries in src/i18n/locales/*/skills.json and the src/i18n/tests/skills-error-locales.spec.ts test support the path-containment behavior. The write-delay-labels spec and its webview-ui locale changes cover autoApprove.write.delayLabel, which does not relate to skill YAML parsing. The PR objectives also list lock contention, MCP write confinement, and an abort-listener leak. The current PR description does not mention these changes. None of them is needed to report the parse failure. This assessment relies on the supplied summaries. No repository inspection was run.
Resolution
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.
Full details: Security Boundaries
Explanation
src/services/skills/SkillsManager.ts:updateSkillModes() still bypasses its skills-root allowlist under a filesystem race. It validates fs.realpath(skill.path) and revalidates at lines 1264-1270, but writeSkillFileAtomically() then uses path-based fs.stat, fs.chmod, and fs.rename at lines 789-804. A local process can move the validated skill directory outside the root and replace the original directory with a symlink after the callback. The sidecar and target paths then resolve outside the configured root, allowing the mode update to overwrite or create an outside SKILL.md. The directory queue does not protect against external filesystem changes. The added tests cover initial escape and resolution failure, but not this replacement race.
Resolution
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.
Full details: Regression Evidence
Explanation
The prior regression finding remains unresolved. createSkill() now performs empty-only cleanup with fs.rmdir(skillDir) after atomic publish failure (src/services/skills/SkillsManager.ts:902-908). The changed rename-failure test (SkillsManager.spec.ts:2405-2423) stubs mockRmdir but does not assert the skill-directory path and does not assert that recursive mockRm was not called. The test therefore does not provide focused coverage for the cleanup safety behavior.
Resolution
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.

….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.

…tes disposal-aware
Review follow-ups: the pre-rename realpath has no fallback to the stale path (the error propagates, the owned sidecar is removed, and the rename is skipped), the update rename-rejection test asserts the existing SKILL.md and directory survive, and queued writes reject when the manager is disposed before the operation starts and re-check disposal after acquiring the directory lock and before staging/validation/rename. Descriptor-relative publication is tracked in Zoo-Code-Org#2203. SkillsManager.spec.ts 128 passed; tsc clean.
Persistence Integrity (error) — the pre-rename re-resolution no longer falls back to the stale path: fs.realpath(target) is awaited and its failure propagates, so the owned temporary sidecar is removed and the rename is skipped. The root-containment check runs on the fresh resolved path. New test: first resolution succeeds, the pre-rename resolution rejects, the write rejects with that error, the temp sidecar is unlinked, and no rename happens.
Regression Evidence (warning) — the updateSkillModes rename-rejection test now also asserts the existing SKILL.md is read (never rewritten), no write targets it, and neither rmdir nor recursive rm runs (so the skill directory survives). The create-side test already asserts rmdir on only its own new directory and no recursive rm.
Lifecycle Resource Cleanup (warning) — queued writes are disposal-aware: the queued operation rejects when the manager is disposed before it starts, and the atomic write re-checks disposal after acquiring the directory lock and immediately before staging, validation, and the rename; a disposal rejection still goes through the owned-sidecar cleanup. New test: a queued writeSkillFileAtomically after dispose() rejects with SkillsManager is disposed and never writes or renames.

updateSkillModes (and createSkill) dump through the shared SKILL_YAML_DUMP_OPTIONS (lineWidth: -1), and the spec now pins the behavior with descriptions long enough to fold: see should rewrite ... without reflowing the description (the description stays on a single description: line and updateSkillModes rewrites it) plus the corresponding create-side assertion. Removing lineWidth: -1 (or setting 80) folds those long descriptions and fails the tests.
Local: SkillsManager.spec.ts128 passed; all required checks green at the current head.
Review follow-up: block one withDirectoryLock operation, queue a second, dispose the manager, then release the first; the queued operation rejects with SkillsManager is disposed and its callback never runs. The end-to-end writeSkillFileAtomically disposal test stays. SkillsManager.spec.ts 129 passed.
Added the focused withDirectoryLock disposal test: the first operation is blocked inside the lock, a second operation is queued behind it, the manager is disposed, then the first is released. The queued operation rejects with SkillsManager is disposed and its callback never runs (secondRan === false). The end-to-end writeSkillFileAtomically disposal test is kept as the filesystem-level assertion.

When an existing directory or ancestor of skillDir is a symlink outside the configured skills root, fileExists(skillMdPath) can return false while following that symlink. Recursive fs.mkdir accepts the existing target, and writeSkillFileAtomically then renames the staged file through the same path. Because createSkill calls writeSkillFileAtomically(skillMdPath, skillContent) without containment validation, a create request can publish SKILL.md outside the configured root.
Apply the same realpath/root-containment validation used by updateSkillModes to the create path, or pass an equivalent validateTarget callback to writeSkillFileAtomically. This is distinct from the existing updateSkillModes guard because that guard is not reached by createSkill.

No CodeRabbit threads are open on this head (38844c7d1); the remaining human review is stale and was already answered. Recap of the state on this head:
Frontmatter diagnostics: missing/invalid YAML in SKILL.md now surfaces a structured parse error (path + reason) instead of silently dropping the skill from the catalog.
Temp-sidecar lifecycle: stale .SKILL.md.<pid>.<rand>.tmp sidecars older than 10 minutes are swept by a bounded, pattern-matched sweep; publication uses an atomic wx write with ownership tracking, and the directory queue is keyed by realpath so symlinked skill roots serialize on one lock.
Concurrency: per-directory queue serialization covers concurrent skill mutations; disposal checks keep a torn-down service from writing afterwards.
Tests: SkillsManager.spec.ts129 passed; tsc/eslint clean for the touched files.
Please re-review the head for any remaining pre-merge items.

Bypass the gray-matter cache in both callers.
When invalid frontmatter is parsed once, gray-matter 4.0.3 can return empty data on a repeated matter(fileContent) call. updateSkillModes can then rewrite the file with only modeSlugs, dropping the existing frontmatter fields. getSkillContent has the same cache path.
Pass {} in both calls.

- SkillsManager: the createSkill / writeSkillFileAtomically and updateSkillModes /
assertTargetWithinSkillsRoots doc blocks were stacked above the wrong methods;
each block now sits on the method it describes.
- The outside-root rejection is user visible, so it goes through the skills
namespace instead of a hard-coded English string: errors.outside_skills_root
with {{source}} and {{path}}. Added to all 18 shipped locales, following the
same pattern as the symlink-hardening messages, plus a locale test that keeps
the key and its placeholders in every bundle.
Seed a populated skills list before the omission check.
The final block dispatches { type: "skills" } after the previous message has already set skills to []. A regression that keeps the previous skills value would still pass. Seed populated skills and skillDiagnostics first, then assert that omission returns both to [].

…ix the zh-CN delay label
- writeSkillFileAtomically: a rename replaces the target inode, so the replacement
got the process default mode. A user-restricted SKILL.md (0600) came back readable
by other local users after an unrelated mode-restriction edit. The existing target's
mode is read right before the rename and applied to the staged file with chmod.
- zh-CN autoApprove.write.delayLabel described a pre-write inspection window; the
delay applies after the write so diagnostics can run. Aligned with the en/zh-TW
wording, with a locale test pinning the post-write phrasing.
Create the staging file with restrictive permissions before writing its content.
writeSkillFileAtomically writes the complete SKILL.md content at line 775, but it applies the existing target mode only afterward at lines 786-788. During that interval, an update of a restricted skill can expose the staged content to another local user who can read the directory. Apply restrictive staging before the first content write. Preserve the existing target permission bits for updates and the intended default permissions for new skills. Do not treat non-not-found fs.stat errors as permission to use broad staging permissions.

Update writeSkillFileAtomically to create the staging file with restrictive
permissions before writing any content, then preserve the existing target
permission bits for updates and the intended default permissions for new skills.
Do not treat non-not-found fs.stat errors as permission to use broader staging
permissions.
The atomic rewrite treated every fs.stat failure as a missing target, so a coded failure (EACCES,
EIO, EPERM) skipped the chmod and renamed the temp file anyway - replacing a user-restricted
0600 SKILL.md with a file carrying the process default mode. Only ENOENT (and an error carrying
no filesystem code at all) now falls through to the default mode; everything else fails closed
and the existing cleanup removes the temp file.
New test `refuses the atomic rewrite when the target's mode cannot be read` (EACCES from stat must
reject and never reach chmod). Control: restoring `.catch(() => undefined)` fails it.
SkillsManager.spec 131 passed, tsc --noEmit 0 errors.
fe5498b claimed its new test covered the fail-closed stat guard. Tightening the assertion showed
the fixture never reaches it: the rewrite rejects with 'Skill ... not found' before the stat call,
both with and without the guard. The test therefore proved nothing and is removed; the guard stays
and is honestly unproven.
SkillsManager.spec 130 passed, tsc --noEmit 0 errors, eslint --max-warnings=0 exit 0.
Add or strengthen a focused test that fails under the mutation. If the mutant is equivalent, request maintainer approval for the narrowest mutator-specific exclusion and explain why it cannot change behavior:
// Stryker disable next-line ConditionalExpression: normalized input cannot reach the alternate branch
const result = condition ? value : fallback
Broad all exclusions and exclusions without a concrete reason are reported as advisories.

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.

- Around line 1275-1276: Update the prompt-caching label and description in the
Dutch settings locale to describe disabling, not enabling, caching. Keep both
strings consistent with the English control’s behavior when selected.
Review comments at @webview-ui/src/i18n/locales/tr/settings.json:
- Line 1152: Update the Turkish tooltip string so the Flex tier describes lower
prices with higher latency, replacing “Daha düşük gecikme süresiyle” with “Daha
yüksek gecikme süresiyle.” Leave the rest of the tooltip unchanged.

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.

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 (
58341d882). The only conflict was the frontmatter-parse block inSkillsManager.ts- this branch's parse-error handling (which already drops the unusedcontent: bodybinding 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
