Conciseness

The body devotes significant space to re-teaching knowledge Claude already has: the conventional-commit format template, the full Types list (feat/fix/docs/style/refactor/perf/test/chore), and standard rules (imperative mood, max 50 chars). The examples and workflow steps are genuinely useful, so this is mostly efficient rather than noticeably verbose, but the redundant sections are more than minor and could be trimmed or reduced to project-specific deviations.

Actionability

Guidance is fully executable: concrete commands (`git diff --cached`, `git commit -m "..."`), an explicit output format spec, and three complete copy-paste-ready examples covering common cases (feat, fix, refactor). No vague or pseudocode guidance appears.

Workflow Clarity

The sequence is clear (run git diff --cached, analyze changes, generate message) and the Execution section provides a user-confirmation checkpoint before `git commit`. It falls short of level 5 because there are no explicit validation steps (e.g., checking that staged changes exist), but the operation is neither destructive nor batch, so the level-3 cap does not apply.

Progressive Disclosure

This is a simple, single-purpose skill with no bundle files, and none are needed: the ~68-line body is self-contained with well-organized sections (Instructions, Commit format, Types, Rules, Examples, Execution) and easy navigation. Content is appropriately placed with no buried or nested references.

Specificity

The description names the domain (commit messages, staged changes) and one concrete action ("Generate a conventional commit message"), but lists no further actions such as analyzing diffs or covering multiple commit types. It exceeds the generic level 2 but does not list several specific actions needed for level 4.

Completeness

The description has a clear "what" ("Generate a conventional commit message for staged changes") but no "Use when..." clause or equivalent trigger guidance inside the description itself — the when-guidance lives in a separate frontmatter when_to_use field. Per the rubric guideline, a missing 'Use when...' clause caps completeness at 3.

Trigger Term Quality

"conventional commit message" and "staged changes" are natural phrases users would say when needing this skill, plus the generic term "commit". A few natural variations are missing (e.g., "git commit", "write a commit message"), so it falls short of comprehensive synonym coverage at level 5.

Distinctiveness Conflict Risk

"Generate a conventional commit message for staged changes" carves out a clear niche (conventional-commit formatting for staged git changes) and closely matches the rubric's good example ("Generate descriptive commit messages by analyzing git diffs"). Triggers are distinct with minimal conflict risk against other skills.
