Lists multiple specific review dimensions: correctness, security, performance, maintainability, testing, and release readiness. Also specifies concrete review targets: pull requests, diffs, and implementation changes.

Clearly answers both 'what' (review PRs/diffs/changes for correctness, security, performance, maintainability, testing, release readiness) and 'when' (explicit 'Use when...' clause with specific trigger scenarios).

Includes strong natural trigger terms users would actually say: 'PR', 'pull request', 'diff', 'patch', 'commit', 'code change', 'review'. These cover the most common variations of how users would phrase such requests.

Clearly scoped to code review of changes/diffs rather than general code writing or analysis. The focus on PR/diff/patch review with specific quality dimensions makes it distinct from general coding skills or static analysis skills.

Every section earns its place. No unnecessary explanations of what code review is or how git works. The content is dense with actionable guidance and avoids padding. The findings bar criteria and severity definitions are tight and useful.

Provides fully executable git and gh CLI commands for every review scenario, a complete output template with specific fields, concrete severity definitions, and a clear findings bar with four specific questions to answer for each finding.

The workflow is clearly sequenced with 8 explicit steps. The review mode section includes important validation/safety checkpoints: restore previous branch, clean up worktrees, ask before disturbing local work, and report any leftover state. The 'ask before reviewing deeply' instruction provides a feedback loop for ambiguous inputs.

The skill provides a clear overview with well-signaled one-level-deep references to five supplementary files (security.md, performance.md, quality.md, testing.md, error-handling.md) with explicit guidance to load only when relevant. Content is appropriately split between the main skill and reference files.
