Conciseness

The body is lean: every line carries task-specific information Claude would not infer on its own ("A single dismissed finding is noise; the same class dismissed several times is a rule", "do not re-run a full PR crawl", the 400–1200 word constraint). There is no explanation of concepts Claude already knows and no padding, matching the score-5 anchor (every token earns its place); score 4 would require identifiable over-explanation, which is absent.

Actionability

Concrete guidance is present: named tool calls (`read_finding_outcomes`, `save_review_style_prompt`), the fields they return, the required payload fields (custom_prompt, analysis_summary, top_reviewers) with a word-count range and an example summary string. This matches the score-4 anchor (concrete commands with minor gaps) rather than 5, because no example of the actual save call with arguments is shown, and how the current custom_prompt is obtained ("it is summarized for you / available via the dashboard record") is left ambiguous.

Workflow Clarity

A clear three-step sequence (read outcomes → reconcile → save) with a decision heuristic ("Look for repetition, not one-offs") and an explicit guard for the destructive case — "If outcomes were empty and nothing changed... re-save the existing prompt unchanged rather than degrading it". This fits the score-4 anchor (clear sequence, most checkpoints present, minor validation gaps); it is not 5 because there is no post-save verification step or feedback loop, and not 3 because the main degradation risk is explicitly validated against.

Progressive Disclosure

The skill is under 50 lines with no bundle files (no references/, scripts/, or assets/ exist) and no external content is needed; the body is organized into three well-labeled sections that each fit on one screen. Per the rubric's simple-skill guideline (under 50 lines, no need for external references), this matches the score-5 anchor of well-organized structure with appropriate content placement.

Specificity

Quotes: "Read confirmed (resolved-by-commit / thumbs-up) and dismissed (thumbs-down) findings, promote the bug patterns the team actually fixes, demote the false-positive patterns, reconcile against the current prompt, and save the refined version" — five concrete, domain-specific actions covering the full workflow. This matches the score-5 anchor (multiple specific concrete actions, comprehensive coverage) and exceeds the score-4 anchor only by being complete rather than having minor gaps.

Completeness

The what is explicit ("Read confirmed... and dismissed... findings, promote..., demote..., reconcile..., and save the refined version") and the when is explicit with a concrete trigger condition ("Use this once outcomes exist; use bootstrap-repo-analysis for a cold-start repo"). Both what and when are clearly answered, matching the score-5 anchor; score 4 would require the when to be less specific than it is here.

Trigger Term Quality

Relevant keywords exist — "refinement", "review-style prompt", "finding outcomes", "confirmed", "dismissed", "false-positive patterns" — but these are internal jargon rather than the natural phrases a user would say (e.g. "update the review prompt", "learn from past review feedback", "recurring bug patterns"). This fits the score-3 anchor (some relevant keywords, missing common variations/synonyms) and is below score 4, which requires broader natural-term coverage.

Distinctiveness Conflict Risk

The niche is sharply delimited — "Nightly refinement of an existing per-repo review-style prompt using this reviewer's own finding outcomes" — and it actively disambiguates from the nearest neighbor skill ("use bootstrap-repo-analysis for a cold-start repo"), matching the score-5 anchor of a clear niche with distinct triggers and minimal conflict risk.
