Conciseness

The ~480-line body is mostly operational but includes sections that could be tightened or cut: "Best Practices" (8 generic bullets), "Multi-Agent Support" (restates the description's triggers), and "Detection Triggers" (repeats quoted phrases already in the frontmatter and Quick Reference). Not anchor 2 because the bulk is templates, commands, and tables rather than explanations of concepts Claude already knows.

Actionability

Guidance is fully executable: copy-paste entry templates, concrete commands ("mkdir -p .learnings", "grep -n \"Pattern-Key: <pattern_key>\" .learnings/LEARNINGS.md", "./skills/self-improvement/scripts/extract-skill.sh skill-name --dry-run"), a worked verbose-to-concise promotion example, and ready-made gitignore snippets. This matches the anchor-5 pattern of copy-paste-ready content covering the common cases.

Workflow Clarity

Multi-step flows are clearly sequenced with most checkpoints present: extraction step 5 "Verify: Read skill in fresh session", the Skill Quality Gates checklist, and the search-first dedupe step in the Simplify & Harden ingestion workflow. Not anchor 5 because the core logging and promotion workflows lack verification steps (e.g., no ID-uniqueness check against existing entries, no confirmation the promoted rule landed in the target file).

Progressive Disclosure

References are well signaled ("Read these only when installing or configuring the skill") and one level deep, but content that should be separate is inlined: the full entry templates in Logging Format duplicate the purpose-built assets/LEARNINGS.md, ERRORS.md, and FEATURE_REQUESTS.md files, and references/examples.md (383 lines) is never linked from the body, leaving it orphaned. Not anchor 2 because the structure, headers, and reference signaling are otherwise good.

Specificity

The description lists multiple concrete actions covering the skill's full lifecycle — "Captures learnings, errors, corrections, and feature requests", "distill into a memory file or new skill", and "review learnings before major tasks" — with concrete objects rather than abstract language. It fits the anchor-5 example's pattern of several verb+object actions with comprehensive coverage; anchor 4 (minor gaps) is too weak since capture, promotion, and review are all explicitly named.

Completeness

Both what ("Captures learnings, errors, corrections, and feature requests to enable continuous improvement") and when (an explicit "Use when: (1)…(5)" enumeration with concrete trigger phrases, plus "Also review learnings before major tasks") are clearly and explicitly stated. This matches the anchor-5 example structure of what + when with concrete trigger phrases; anchor 4's "when could be more explicit" does not apply.

Trigger Term Quality

Natural user phrases are quoted directly ("'No, that's wrong...'", "'Actually...'") alongside "knowledge is outdated or incorrect" and "a better approach is discovered", giving good keyword coverage. Not anchor 5 because it omits file extensions (e.g., ".learnings/") and common synonyms ("lessons", "user feedback") that the top anchor requires.

Distinctiveness Conflict Risk

The description carves a clear niche (passive accumulation and promotion layer) and explicitly resolves conflicts with siblings: "use `self-healing` instead" for active runtime failures and "use self-improvement-ci" for CI-only/headless capture. Trigger phrases and boundary guidance are distinct, so minimal conflict risk per anchor 5.
