Conciseness

At ~70 words the body is lean and assumes Claude's competence: 'Keep PR titles and bodies concise; do not write essays. Focus on bullet points, Mermaid diagrams, and useful code samples.' Every directive carries new information with no padding or explanation of concepts Claude already knows, matching anchor 5 ('lean and efficient; every token earns its place').

Actionability

Directives are concrete and case-specific: 'include a before/after table with uploaded images or videos', 'For benchmarks, always include a before/after table', 'describe the final squash-merge outcome'. It falls short of anchor 5 because there is no example title or body template to copy, leaving minor gaps between the rules and a concrete artifact.

Workflow Clarity

This is a simple single-task skill and the action (write a concise PR title/body) is unambiguous, with explicit case branches for visual changes, benchmarks, and impressive changes. It does not reach 5 because 'truly impressive changes' leaves ambiguous when the technical-blog style applies, a minor checkpoint gap rather than the incoherence of anchor 3 or below.

Progressive Disclosure

The skill is under 50 lines with no bundle files and no need for external references, and the content is short and scannable. It misses anchor 5's bar of 'well-organized sections' — it is a single unsegmented paragraph where per-case rules (visual, benchmark, impressive changes) could be broken out — so anchor 4 ('good structure; minor organization gaps') is the best fit.

Specificity

The description names the domain ('pull request title or body') and the user's activity ('writing or editing'), but states no concrete capability of the skill itself — nothing about what conventions or guidance it provides. This matches anchor 2 ('names the domain but actions are minimal or generic') better than anchor 3, whose example ('Processes PDF files and extracts content') describes skill actions rather than the user's task.

Completeness

Only the 'when' is present ('Use when writing or editing a pull request title or body') with no 'what' at all — the skill's actual function is never stated. This exactly matches anchor 2 ('only when is present without what'); it cannot reach anchor 3, which requires a clear 'what'.

Trigger Term Quality

Natural terms are well covered: 'writing', 'editing', 'pull request', 'title', 'body' — phrases a user would plausibly say. It falls short of anchor 5 because common synonyms like 'PR', 'PR description', or 'draft pull request' are missing, matching anchor 4 ('good keyword coverage; a few natural terms missing').

Distinctiveness Conflict Risk

PR title/body authorship is a distinct niche with clear triggers, with only minor overlap risk against closely related commit-message or general-writing skills. It fits anchor 4 ('mostly distinct; minor overlap risk') rather than anchor 5, since it does not fully disambiguate from adjacent git-workflow skills.
