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:
  5. Agents #1 & #2: Audit for CLAUDE.md compliance
  6. Agent #3: Scan for obvious bugs in changes
  7. Agent #4: Analyze git blame/history for context-based issues
  8. Scores each issue 0-100 for confidence level
  9. Filters out issues below 80 confidence threshold
  10. Outputs review (to terminal by default, or as PR comment with --comment flag)

Usage:

bash
/code-review [--comment]

Options:

  • --comment: Post the review as a comment on the pull request (default: outputs to terminal only)

Example workflow:
