Review Mode

Run a comprehensive code review on current branch changes.

Additional review focus

"$ARGUMENTS"

If provided, the above gives optional extra constraints or focus areas for the review. By default, the skill reviews all current branch changes without needing any arguments.

Process

Subagent 1: Review

Use a subagent to carry out the review.

IMPORTANT: This agent is a reviewer only - do NOT modify any code. Report issues for the fix agent to handle.

Before starting the review, the subagent should:

1. Read the plan file for context: Find and read plan-*.md in the current directory to understand the feature intent, expected changes, and architecture decisions.
2. The additional review focus above (if provided) gives extra constraints on what to concentrate on.

Then proceed with the full review workflow:

#### Step 1: Identify Changed Files

Check what files have been modified:

git status
git diff --name-only

Parse the output to get list of modified Python files.

#### Step 2: Deep Code Review

Review each modified file for:

Security Concerns:

• SQL injection vulnerabilities
• Unsafe data handling
• Credential exposure
• Input validation issues

Code Quality:

• Functions over 50 lines (should be broken down)
• Duplicated code patterns
• Missing type annotations
• Poor naming conventions
• Spaghetti code / complex control flow

Integration Issues:

• Breaking changes to existing APIs
• Missing error handling
• Race conditions
• Resource leaks

Edge Cases:

• Null/None handling
• Empty collections
• Boundary conditions
• Error scenarios

For each issue found, provide:

• File path and line number
• Severity (BLOCKING, HIGH, MEDIUM, LOW)
• Detailed explanation
• Suggested fix

#### Step 3: Generate Review Report

Create review.md with the following structure:

# Code Review Report

**Date**: [Current date]
**Branch**: [Branch name]
**Reviewer**: Code Review Agent

## Summary

[High-level summary of changes and overall assessment]

**Overall Status**: APPROVED / CHANGES REQUESTED / REJECTED

## Code Review Findings

### BLOCKING Issues
[Critical issues - these MUST be fixed]

### High Priority
[Security concerns, major quality issues]

### Medium Priority
[Code quality improvements, refactoring suggestions]

### Low Priority / Suggestions
[Nice-to-have improvements, style suggestions]

## Test Results

[Test run summary and any failures]

## Files Reviewed

[List of all files checked with brief notes]

Write the report to `review.md` in the current directory.

Subagent 2: Codex critique pass

After the review subagent writes review.md and before the fix subagent runs, get a second opinion from Codex:

• Critique: Invoke the /codex skill on the current branch diff (per its PR diff review recipe). Ask it to find things the primary review missed — bugs, security issues, design smells, untested paths, missed edge cases.
• Triage: Separate valid Codex findings from noise.
• Merge: Append the valid new findings into review.md under the appropriate severity sections, tagged as (Codex) so the fix subagent picks them up in the same pass.

Subagent 3: Fix

After the review and Codex critique are merged into review.md, use another subagent (opus high effort) to fix all issues:

1. Read review.md in the current directory
2. Fix all issues found in the review (including Codex-tagged items)
3. Briefly summarize what was fixed, calling out which fixes came from the Codex second pass

Important Notes

• Be thorough and skeptical - better to catch issues now than in production
• Provide specific feedback - include file:line references
• Explain the "why" - don't just say what's wrong, explain why it matters
• Be constructive - suggest fixes, not just criticism
