Code Review

Code Review Plugin

Automated code review for pull requests using multiple specialized agents with confidence-based scoring to filter false positives.

Overview

The Code Review Plugin automates pull request review by launching multiple agents in parallel to independently audit changes from different perspectives. It uses confidence scoring to filter out false positives, ensuring only high-quality, actionable feedback is posted.

Commands

/code-review

Performs automated code review on a pull request using multiple specialized agents.

What it does:

1. Checks if review is needed (skips closed, draft, trivial, or already-reviewed PRs)
2. Gathers relevant CLAUDE.md guideline files from the repository
3. Summarizes the pull request changes
4. Launches 4 parallel agents to independently review:
   • Agents #1 & #2: Audit for CLAUDE.md compliance
   • Agent #3: Scan for obvious bugs in changes
   • Agent #4: Analyze git blame/history for context-based issues
5. Scores each issue 0-100 for confidence level
6. Filters out issues below 80 confidence threshold
7. Posts review comment with high-confidence issues only

Usage:

/code-review

Example workflow:

# On a PR branch, run:
/code-review

# Claude will:
# - Launch 4 review agents in parallel
# - Score each issue for confidence
# - Post comment with issues ≥80 confidence
# - Skip posting if no high-confidence issues found

Features:

• Multiple independent agents for comprehensive review
• Confidence-based scoring reduces false positives (threshold: 80)
• CLAUDE.md compliance checking with explicit guideline verification
• Bug detection focused on changes (not pre-existing issues)
• Historical context analysis via git blame
• Automatic skipping of closed, draft, or already-reviewed PRs
• Links directly to code with full SHA and line ranges
