Lists multiple specific concrete actions: 'Find bugs, security vulnerabilities, and code quality issues in local branch changes.' These are distinct, concrete capabilities.

Clearly answers both what ('Find bugs, security vulnerabilities, and code quality issues in local branch changes') and when ('Use when asked to review changes, find bugs, security review, or audit code on the current branch') with explicit trigger guidance.

Includes natural keywords users would say: 'review changes', 'find bugs', 'security review', 'audit code', 'current branch'. These cover common variations of how users would request code review.

Scoped specifically to local branch changes and code review/audit, which distinguishes it from general coding skills, linting tools, or broader code assistance. The 'local branch changes' qualifier creates a clear niche.

Every section serves a clear purpose. No unnecessary explanations of what bugs or security vulnerabilities are. The checklists are dense with actionable items and no padding. Claude doesn't need to be told what SQL injection is—just to check for it.

Provides a concrete git command for getting the diff, specific checklists to evaluate against, a clear output format with severity levels and required fields, and explicit instructions like 'read each changed file individually.' The guidance is specific and directly executable.

Five clearly sequenced phases with logical dependencies (gather input → map attack surface → check against checklist → verify findings → audit completeness). Phase 4 is an explicit verification/feedback loop ensuring issues are real, and Phase 5 is a pre-conclusion audit that prevents premature or incomplete reporting.

For a skill of this size (~60 lines of substantive content), the structure is well-organized with clear section headers and logical progression. No external references are needed since the content is self-contained and appropriately scoped. The checklist format enables quick scanning.
