Conciseness

The body is lean and assumes Claude's competence ('Write commit messages terse and exact. No fluff. Why over what.') with zero padding and no explanation of git or Conventional Commits basics; every token earns its place.

Actionability

Fully concrete guidance: exact subject format, enumerated types, char limits, an explicit never-includes list, and two complete copy-paste-ready example messages covering the common cases (feature with body, breaking change).

Workflow Clarity

A simple single-purpose skill whose single action is unambiguous: inspect the change, output the message as a paste-ready code block. The skill explicitly excludes destructive actions (no commit, no stage, no amend), so no validation cap applies.

Progressive Disclosure

A simple, well-sectioned skill (Rules, Examples, Auto-Clarity, Boundaries) with all content appropriately inline and no external files needed. Held at 4 rather than 5 because the body slightly exceeds the simple-skill line and the Auto-Clarity section partially duplicates the Body rules, a minor organization gap.

Specificity

The description names concrete, parameterized capabilities ('Ultra-compressed commit message generator', 'Conventional Commits format. Subject ≤50 chars, body only when "why" isn't obvious'), but describes a single core action with format constraints rather than several distinct actions, which is the anchor-5 pattern.

Completeness

It explicitly answers both what it does (generate ultra-compressed Conventional Commits messages with subject ≤50 chars) and when to use it, with a 'Use when...' clause listing concrete trigger phrases plus auto-trigger guidance.

Trigger Term Quality

Good natural keyword coverage ('write a commit', 'commit message', 'generate commit', '/commit', 'staging changes'), but common variations users actually say such as 'make a commit' or 'git commit' are missing.

Distinctiveness Conflict Risk

Clear niche (commit-message generation) with distinct, domain-specific triggers closely matching the rubric's own good example ('Generate descriptive commit messages by analyzing git diffs'); minimal overlap with other skills.
