Conciseness

Lean and efficient throughout — terse rules ('No fluff. Why over what.'), no explanation of what a commit or Conventional Commits is, and every line earns its place; assumes Claude's competence.

Actionability

Fully actionable: concrete subject format, enumerated types, char limits, and two complete copy-paste-ready example messages covering the common cases (regular feature and breaking change).

Workflow Clarity

For a single-purpose skill the action is unambiguous, and the Auto-Clarity section adds an explicit checkpoint — always include a body for breaking changes, security fixes, migrations, and reverts — giving a clear validation rule for the risky cases.

Progressive Disclosure

Well-organized single-file skill under 50 lines with clear section headers (Rules, Examples, Auto-Clarity, Boundaries) and no need for external references; per the simple-skill guidance this scores top marks.

Specificity

Names the domain (commit message generator) and several concrete actions — 'Cuts noise', 'preserving intent and reasoning', Conventional Commits format, subject ≤50 chars, body only when why isn't obvious — covering most of what the skill does with only minor gaps.

Completeness

Explicitly answers both 'what' (ultra-compressed commit message generator, Conventional Commits, subject/body constraints) and 'when' ('Use when user says...' with concrete trigger phrases), matching the top anchor.

Trigger Term Quality

Comprehensive natural trigger phrases users would actually say: 'write a commit', 'commit message', 'generate commit', '/commit', and '/caveman-commit', plus an auto-trigger condition (staging changes), covering synonyms and exact command forms.

Distinctiveness Conflict Risk

Clear niche (terse Conventional-Commits messages) with distinct trigger terms and an explicit '/caveman-commit' command, giving it minimal overlap with other skills.
