Agent Skills: diff-review-doc

Generate comprehensive, reviewer-ready code review documents from git diffs. Use this when the user provides code changes (git diff output, file changes, or asks to review code changes) and wants a structured review document. Creates detailed analysis covering change overview, business flow, key code explanation, risk assessment, and review recommendations. Supports both manual diff input and automatic git workspace detection. Particularly useful for reviewing pull requests, feature branches, or any code changes requiring thorough documentation for reviewers.
