Code Review

CodingIntermediate

Analyzes changes on the current branch or specific files, systematically reviewing for logic errors, security vulnerabilities, performance issues, and code style.

Junior developer anxious before submitting a PR? Run /review to catch issues before the senior reviewer does

Senior developer with a backlog of review requests? Use automated first-pass review to reduce review burden

Skill Code

# Code Review Skill ## Trigger: /review [file or branch] When invoked: 1. Get changes: - If file specified: read that file - If branch: run `git diff main...HEAD` - If nothing: run `git diff` 2. Analyze for: - 🔴 Logic errors and edge cases - 🔴 Security vulnerabilities (injection, XSS, etc.) - 🟡 Performance concerns - 🟡 Error handling gaps - 🟢 Code style and readability - 🟢 Test coverage suggestions 3. Output format: --- ## 🔍 Code Review ### 🔴 Critical (must fix) - [issue]: [explanation + suggestion] ### 🟡 Suggestions (should consider) - [issue]: [explanation + suggestion] ### 🟢 Positive - [what's done well] ### Summary [1-2 sentence overall assessment] ---

How Code Review Works

Code Review collects changed code on your current branch, runs four parallel checks — logic errors, security vulnerabilities, performance issues, and code style — then classifies findings by severity from Critical to Suggestion.

When to Use Code Review

Invaluable before submitting a PR when you want a thorough first-pass review, or for senior developers who need to triage a backlog of review requests by letting the skill handle the mechanical checks.

Key Strengths

  • Four-dimensional analysis covers logic, security, performance, and style
  • Severity-based classification helps prioritize fixes
  • Catches issues before human reviewers see the code
  • Reduces review turnaround time for the entire team
