github-code-review（GitHub 代码审查）

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"

🔄 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 (< 100 lines): ring topology
# Medium PR (100-500 lines): mesh topology
# Large PR (> 500 lines): hierarchical topology
npx ruv-swarm github pr-topology --pr 123

🎬 PR Comment Commands

Execute swarm commands directly from PR comments:

<!-- In PR comment -->
$swarm init mesh 6
$swarm spawn coder "Implement authentication"
$swarm spawn tester "Write unit tests"
$swarm status
$swarm review --agents security,performance

// 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');
  }

🔐 Security Considerations

Best Practices

1. Token Permissions: Ensure GitHub tokens have minimal required scopes
2. Command Validation: Validate all PR comments before execution
3. Rate Limiting: Implement rate limits for PR operations
4. Audit Trail: Log all swarm operations for compliance
5. Secret Management: Never expose API keys in PR comments or logs

Security Checklist

• GitHub token scoped to repository only
• Webhook signatures verified
• Command injection protection enabled
• Rate limiting configured
• Audit logging enabled
• Secrets scanning active
• Branch protection rules enforced

📚 Best Practices

1. Review Configuration

• ✅ Define clear review criteria upfront
• ✅ Set appropriate severity thresholds
• ✅ Configure agent specializations for your stack
• ✅ Establish override procedures for emergencies

2. Comment Quality

• ✅ Provide actionable, specific feedback
• ✅ Include code examples with suggestions
• ✅ Reference documentation and best practices
• ✅ Maintain respectful, constructive tone

3. Performance Optimization

• ✅ Cache analysis results to avoid redundant work
• ✅ Use incremental reviews for large PRs
• ✅ Enable parallel agent execution
• ✅ Batch comment operations efficiently

4. PR Templates

<!-- .github$pull_request_template.md -->
## Swarm Configuration
- Topology: [mesh$hierarchical$ring$star]
- Max Agents: [number]
- Auto-spawn: [yes$no]
- Priority: [high$medium$low]

## Tasks for Swarm
- [ ] Task 1 description
- [ ] Task 2 description
- [ ] Task 3 description

## Review Focus Areas
- [ ] Security review
- [ ] Performance analysis
- [ ] Architecture validation
- [ ] Accessibility check

5. Auto-Merge When Ready

# Auto-merge when swarm completes and passes checks
SWARM_STATUS=$(npx ruv-swarm github pr-status 123)

if [[ "$SWARM_STATUS" == "complete" ]]; then
  # Check review requirements
  REVIEWS=$(gh pr view 123 --json reviews --jq '.reviews | length')

  if [[ $REVIEWS -ge 2 ]]; then
    # Enable auto-merge
    gh pr merge 123 --auto --squash
  fi
fi

🔗 Integration with Claude Code

Workflow Pattern

1. Claude Code reads PR diff and context
2. Swarm coordinates review approach based on PR type
3. Agents work in parallel on different review aspects
4. Progress updates posted to PR automatically
5. Final review performed before marking ready

Example: Complete PR Management

[Single Message - Parallel Execution]:
  // Initialize coordination
  mcp__claude-flow__swarm_init { topology: "hierarchical", maxAgents: 5 }
  mcp__claude-flow__agent_spawn { type: "reviewer", name: "Senior Reviewer" }
  mcp__claude-flow__agent_spawn { type: "tester", name: "QA Engineer" }
  mcp__claude-flow__agent_spawn { type: "coordinator", name: "Merge Coordinator" }

  // Create and manage PR using gh CLI
  Bash("gh pr create --title 'Feature: Add authentication' --base main")
  Bash("gh pr view 54 --json files,diff")
  Bash("gh pr review 54 --approve --body 'LGTM after automated review'")

  // Execute tests and validation
  Bash("npm test")
  Bash("npm run lint")
  Bash("npm run build")

  // Track progress
  TodoWrite { todos: [
    { content: "Complete code review", status: "completed", activeForm: "Completing code review" },
    { content: "Run test suite", status: "completed", activeForm: "Running test suite" },
    { content: "Validate security", status: "completed", activeForm: "Validating security" },
    { content: "Merge when ready", status: "pending", activeForm: "Merging when ready" }
  ]}

🆘 Troubleshooting

Common Issues

Solution:

# 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

<$details>

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

<$details>

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
