Conciseness

The body is dense and rule-per-sentence with no beginner-concept padding — e.g. "Candidates are the .md files under `<root>/solutions/`, excluding `README.md` and anything under `_archived/`" — assuming Claude's competence throughout. It sits below anchor 5 because of trimmable rhetorical rationale ("The store only compounds value if every doc can be trusted" and the similar closing flourish in Discoverability) and a somewhat convoluted Worth-lens paragraph that re-explains the confirm-before-investigate rule.

Actionability

Concrete, executable gating throughout: exact config-resolution steps ("Read `docs_root` from `<repo-root>/.compound-engineering/config.yaml` only (`<repo-root>` = `git rev-parse --show-toplevel`)"), a copy-paste numbered-options question block, and a verbatim subagent clause. It stops short of anchor 5 because the operational substance of most steps (classification criteria, per-doc fix procedures) lives one level deeper in the references — the body is an orchestrator that gates on reading them rather than containing the executable detail itself.

Workflow Clarity

A clearly sequenced pipeline (Mode → Worth lens → Artifact Root → Scope → Investigate → Classify → Execute → Vocabulary Capture → Report → Commit → Discoverability) with explicit error-recovery loops in the body: "A failed write is recorded as **recommended**, and the run continues", the git-failure fallback, and the blocking-question-or-numbered-options fallback. For a batch/destructive skill, anchor 5 requires explicit validation steps, but the body only names the validation machinery ("the auto-delete rule and its pre-checks", "unverifiable-is-not-false") and delegates its content to classify.md — a minor validation gap relative to anchor 5, comfortably above anchor 3.

Progressive Disclosure

Model progressive disclosure: an ~80-line overview that splits all detail across ten reference files, each verified to exist, each clearly signaled at the exact workflow point it is needed ("Read `references/classify.md` before assigning any of them"), with scripts and the assets template pushed out of the overview. Reference cross-links (e.g. per-action-flows.md → classify.md) target files also reachable directly from the body, keeping navigation one level deep and easy — matching anchor 5.

Specificity

The description names the domain ("captured learnings" against the current codebase) and one core action ("Refresh") plus four concrete audit conditions ("stale, overlapping, superseded, or drifted"), but does not list the several distinct actions the skill actually performs (update, consolidate, replace, delete, report, commit). This matches anchor 3 (domain and 1-2 concrete actions, not comprehensive); it is below anchor 4 because the condition list enumerates what is checked, not multiple specific actions taken.

Completeness

It explicitly answers both parts: what ("Refresh the repo's captured learnings against the current codebase") and when ("Use when auditing stale, overlapping, superseded, or drifted learnings") with concrete trigger phrases, mirroring the anchor-5 good example structure. It is not anchor 4 because the 'when' clause is already explicit and trigger-phrase-specific rather than needing more precision.

Trigger Term Quality

Natural trigger terms are well covered — "auditing", "stale", "overlapping", "superseded", "drifted", "learnings" — and the negative boundary ("avoid general refactor, debugging, or code review") sharpens matching. It falls short of anchor 5 because common user phrasings like "outdated", "prune", or "clean up the solutions docs" are absent (clean-up intent is handled only inside the body).

Distinctiveness Conflict Risk

A clear niche (maintaining a captured-learnings store) with distinct triggers, plus an explicit de-confliction clause ("avoid general refactor, debugging, or code review unless the learnings store is explicit") that fences off its nearest competing skills. Minimal conflict risk, matching anchor 5.
