-description: Audit, prune, and update the project's architecture documentation — `codev/resources/arch.md` and `codev/resources/lessons-learned.md`. Use this skill when running MAINTAIN's arch-doc step, or when asked to update / audit / prune `codev/resources/arch.md` or `codev/resources/lessons-learned.md`. The skill is opinionated about what NOT to include in these files (per-spec changelogs, exhaustive enumerations, aspirational state, duplicate meta-spec content) and ships two operating modes: diff-mode (apply a specific change) and audit-mode (propose cuts with reasons). It edits files directly via normal file-edit tooling and does not invoke destructive shell commands.

+# bugfix-922 thread
+
+## Investigate
+Reproduced the YAML parse error with the snippet in the issue. Root cause is
+exactly as described: unquoted `description:` scalar containing
+`two operating modes: diff-mode` — the bare `: ` makes the parser try to
+nest a mapping inside the scalar.
+
+## Fix
+One-line change: wrapped the entire `description:` value in double quotes.
+No embedded double quotes in the string, so no escaping needed. Verified
+with the issue's repro snippet (now exits 0, parses successfully, prints
+the description starting with "Audit, prune, and update...").
+
+Scope adhered to: only `codev-skeleton/.claude/skills/update-arch-docs/SKILL.md`
+modified. The three live working copies (`.claude/`, `.codex/`, `.gemini/`)
+are intentionally left untouched per issue scope.
+
+## Flaky tests
+`pnpm test` fails locally on 3 pre-existing flaky tests in
+`packages/codev/src/terminal/__tests__/session-manager.test.ts`, tracked in
+#905. Not fixed here — out of scope.
+
+Note on intermediate history: I initially skipped these to unblock porch's
+phase-advance check (per the role file's "Handling Flaky Tests" section),
+but the architect corrected me — #905 documents that the same skip was
+already attempted and reverted from PR #904 as out-of-scope. The skip
+commit was reverted (`fe08391c`); diff vs main for the test file is empty.
+
+## PR
+Pushing to `mohidmakhdoomi/codev` fork per builder preference; PR
+fork → upstream (`cluesmith/codev`).
