review

/review - Code Review

Review code for bugs, security issues, performance problems, and readability improvements.

Usage

/review [file or directory]

Instructions

When the user invokes /review, perform a thorough code review of the specified file, directory, or the most recently edited files if no target is given.

Review Categories

Analyze the code across these dimensions and report findings grouped by category:

1. Bugs - Logic errors, off-by-one errors, null/undefined access, race conditions, unhandled edge cases
2. Security - Injection vulnerabilities (SQL, XSS, command), hardcoded secrets, insecure defaults, missing input validation
3. Performance - Unnecessary allocations, N+1 queries, missing indexes, blocking operations, inefficient algorithms
4. Readability - Unclear naming, overly complex functions, missing or misleading comments, inconsistent style

Output Format

For each finding, report:

• File and line number (e.g., src/auth.ts:42)
• Severity: Critical, Warning, or Info
• Category: Bug, Security, Performance, or Readability
• Description: What the issue is and why it matters
• Suggestion: How to fix it, with a code snippet when helpful

Behavior

• If no file or directory is specified, review files changed in the current git working tree (git diff --name-only and git diff --cached --name-only).
• Skip binary files, lock files, and generated files.
• Prioritize findings by severity (Critical first).
• At the end, provide a brief summary with counts by category and severity.
