Github Code Review

GitHub Code Review Skill

> AI-Powered Code Review: Deploy specialized review agents to perform comprehensive, intelligent code reviews that go beyond traditional static analysis.

🎯 Quick Start

Simple Review

# Initialize review swarm for PR
gh pr view 123 --json files,diff | npx ruv-swarm github review-init --pr 123

# Post review status
gh pr comment 123 --body "🔍 Multi-agent code review initiated"

Complete Review Workflow

# Get PR context with gh CLI
PR_DATA=$(gh pr view 123 --json files,additions,deletions,title,body)
PR_DIFF=$(gh pr diff 123)

# Initialize comprehensive review
npx ruv-swarm github review-init \
  --pr 123 \
  --pr-data "$PR_DATA" \
  --diff "$PR_DIFF" \
  --agents "security,performance,style,architecture,accessibility" \
  --depth comprehensive

🚀 Core Features

Multi-Agent Review System

Deploy specialized AI agents for comprehensive code review:

# Initialize review swarm with GitHub CLI integration
PR_DATA=$(gh pr view 123 --json files,additions,deletions,title,body)
PR_DIFF=$(gh pr diff 123)

# Start multi-agent review
npx ruv-swarm github review-init \
  --pr 123 \
  --pr-data "$PR_DATA" \
  --diff "$PR_DIFF" \
  --agents "security,performance,style,architecture,accessibility" \
  --depth comprehensive

# Post initial review status
gh pr comment 123 --body "🔍 Multi-agent code review initiated"

Benefits:

• ✅ Parallel review by specialized agents
• ✅ Comprehensive coverage across multiple domains
• ✅ Faster review cycles with coordinated analysis
• ✅ Consistent quality standards enforcement

🤖 Specialized Review Agents

Security Review Agent

Focus: Identify security vulnerabilities and suggest fixes

# Get changed files from PR
CHANGED_FILES=$(gh pr view 123 --json files --jq '.files[].path')

# Run security-focused review
SECURITY_RESULTS=$(npx ruv-swarm github review-security \
  --pr 123 \
  --files "$CHANGED_FILES" \
  --check "owasp,cve,secrets,permissions" \
  --suggest-fixes)

# Post findings based on severity
if echo "$SECURITY_RESULTS" | grep -q "critical"; then
  # Request changes for critical issues
  gh pr review 123 --request-changes --body "$SECURITY_RESULTS"
  gh pr edit 123 --add-label "security-review-required"
else
  # Post as comment for non-critical issues
  gh pr comment 123 --body "$SECURITY_RESULTS"
fi

🔄 PR-Based Swarm Management

Create Swarm from PR

# Create swarm from PR description using gh CLI
gh pr view 123 --json body,title,labels,files | npx ruv-swarm swarm create-from-pr

# Auto-spawn agents based on PR labels
gh pr view 123 --json labels | npx ruv-swarm swarm auto-spawn

# Create swarm with full PR context
gh pr view 123 --json body,labels,author,assignees | \
  npx ruv-swarm swarm init --from-pr-data

Label-Based Agent Assignment

Map PR labels to specialized agents:

{
  "label-mapping": {
    "bug": ["debugger", "tester"],
    "feature": ["architect", "coder", "tester"],
    "refactor": ["analyst", "coder"],
    "docs": ["researcher", "writer"],
    "performance": ["analyst", "optimizer"],
    "security": ["security", "authentication", "audit"]
  }
}

Topology Selection by PR Size

# Automatic topology selection based on PR complexity
# Small PR ( 500 lines): hierarchical topology
npx ruv-swarm github pr-topology --pr 123

🎬 PR Comment Commands

Execute swarm commands directly from PR comments:

/swarm init mesh 6
/swarm spawn coder "Implement authentication"
/swarm spawn tester "Write unit tests"
/swarm status
/swarm review --agents security,performance

Webhook Handler for Comment Commands

// webhook-handler.js
const { createServer } = require('http');
const { execSync } = require('child_process');

createServer((req, res) => {
  if (req.url === '/github-webhook') {
    const event = JSON.parse(body);

    if (event.action === 'opened' && event.pull_request) {
      execSync(`npx ruv-swarm github pr-init ${event.pull_request.number}`);
    }

    if (event.comment && event.comment.body.startsWith('/swarm')) {
      const command = event.comment.body;
      execSync(`npx ruv-swarm github handle-comment --pr ${event.issue.number} --command "${command}"`);
    }

    res.writeHead(200);
    res.end('OK');
  }
}).listen(3000);

🚪 Quality Gates & Checks

Status Checks

# Required status checks in branch protection
protection_rules:
  required_status_checks:
    strict: true
    contexts:
      - "review-swarm/security"
      - "review-swarm/performance"
      - "review-swarm/architecture"
      - "review-swarm/tests"

Define Quality Gates

# Set quality gate thresholds
npx ruv-swarm github quality-gates \
  --define '{
    "security": {"threshold": "no-critical"},
    "performance": {"regression": "
Issue: Review agents not spawning

**Solution:**
```bash
# Check swarm status
npx ruv-swarm swarm-status

# Verify GitHub CLI authentication
gh auth status

# Re-initialize swarm
npx ruv-swarm github review-init --pr 123 --force

Issue: Comments not posting to PR

Solution:

# Verify GitHub token permissions
gh auth status

# Check API rate limits
gh api rate_limit

# Use batch comment posting
npx ruv-swarm github review-comments --pr 123 --batch

Issue: Review taking too long

Solution:

# Use incremental review for large PRs
npx ruv-swarm github review-init --pr 123 --incremental

# Reduce agent count
npx ruv-swarm github review-init --pr 123 --agents "security,style" --max-agents 3

# Enable parallel processing
npx ruv-swarm github review-init --pr 123 --parallel --cache-results
