Lists multiple concrete actions: generates commit messages, cuts noise while preserving intent/reasoning, uses Conventional Commits format, enforces subject ≤50 chars constraint, includes body only when 'why' isn't obvious.

Clearly answers both 'what' (ultra-compressed commit message generator with Conventional Commits format, subject ≤50 chars, body only when needed) and 'when' (explicit 'Use when...' clause with multiple trigger phrases plus auto-trigger condition).

Excellent coverage of natural trigger terms: 'write a commit', 'commit message', 'generate commit', '/commit', '/caveman-commit', and 'staging changes'. These are phrases users would naturally say when needing this skill.

Highly distinctive with a clear niche: commit message generation with a specific style (ultra-compressed, caveman). The unique slash commands and specific format constraints make it unlikely to conflict with other skills.

Every line earns its place. No explanations of what Conventional Commits are or how git works. The anti-patterns ('What NEVER goes in') are terse and high-value. The writing style itself embodies the skill's philosophy of terseness.

Provides concrete format rules, specific type lists, exact character limits, and complete before/after examples with realistic diffs. The examples show both subject-only and subject+body patterns with real commit messages that are copy-paste ready.

This is a single-task skill (generate a commit message) with clear decision points: when to add a body, when body is mandatory (breaking changes, security fixes, data migrations, reverts), and explicit boundaries about what the skill does NOT do. The workflow is unambiguous for a single-output task.

For a standalone skill under 50 lines with no need for external references, the content is well-organized into logical sections (Rules, Examples, Auto-Clarity, Boundaries). No monolithic walls of text, and no unnecessary file splitting needed.
