Conciseness

The body is lean and 'caveman'-terse — 'Write commit messages terse and exact. No fluff. Why over what.' — with no explanation of concepts Claude already knows; every token earns its place.

Actionability

Concrete, copy-paste-ready guidance: enumerated types, char limits, imperative-mood rules, and full before/after commit examples with body and trailers, all directly executable.

Workflow Clarity

A simple single-task skill whose action is unambiguous — 'Output the message as a code block ready to paste' — with explicit non-destructive Boundaries (no commit, stage, or amend), so the simple-skill exception applies and no validation checkpoint is required.

Progressive Disclosure

No bundle files exist and none are needed; content is organized into well-signaled sections (Rules, Examples, Auto-Clarity, Boundaries) with no nested references, satisfying the simple-skill progressive-disclosure criterion.

Specificity

Lists multiple concrete actions and constraints — 'Ultra-compressed commit message generator', 'Cuts noise from commit messages while preserving intent', 'Conventional Commits format', 'Subject ≤50 chars', 'body only when why isn't obvious' — matching the 'Lists multiple specific concrete actions' anchor.

Completeness

Clearly answers both what (terse Conventional Commits generator with stated constraints) and when (an explicit 'Use when...' clause with concrete triggers), matching the top anchor.

Trigger Term Quality

Explicit natural triggers users would say — 'write a commit', 'commit message', 'generate commit', '/commit', '/caveman-commit', plus 'Auto-triggers when staging changes' — giving good coverage of common variations.

Distinctiveness Conflict Risk

Narrow niche (commit-message generation only) with distinct, specific triggers and a named slash command, making conflict with other skills unlikely.
