Project Overview

Build a code review assistant that automatically reviews PRs, manages issues, and provides code quality feedback using OpenClaw and GitHub integration.

Step 1: GitHub MCP Configuration

// config.js
{
  mcp: {
    servers: [{
      name: 'github',
      type: 'stdio',
      command: 'npx',
      args: ['@mcp-servers/github'],
      env: {
        GITHUB_TOKEN: process.env.GITHUB_TOKEN
      }
    }]
  }
}

Step 2: PR Review Workflow

# GitHub Workflow (AGENTS.md)

## Pull Request Review
1. Fetch PR diff and metadata
2. Analyze changes for:
   - Code style consistency
   - Potential bugs or issues
   - Test coverage implications
   - Security concerns
3. Generate structured review
4. Post as PR comment

## Review Format
- Summary of changes
- Potential issues (critical/warning/suggestion)
- Recommended improvements
- Approval recommendation

Step 3: Automated PR Review

// Trigger: "Review PR #123"

const pr = await github.getPullRequest({
  owner: 'user',
  repo: 'project',
  number: 123
});

const diff = await github.getPullRequestDiff({ ... });

// Analyze with LLM
const review = await analyzePRDiff(diff, pr);

// Post review
await github.createPullRequestReview({
  owner: 'user',
  repo: 'project',
  number: 123,
  body: review.summary,
  comments: review.lineComments,
  event: review.shouldApprove ? 'APPROVE' : 'REQUEST_CHANGES'
});

Step 4: Issue Management

// "Summarize open issues"

const issues = await github.listIssues({
  owner: 'user',
  repo: 'project',
  state: 'open'
});

const summary = categorizeIssues(issues);

// Response format
"📋 Open Issues Summary:
- 🐛 Bugs (8): 3 critical, 5 normal
- ✨ Features (12): 4 in progress
- 📝 Docs (3): All low priority

Top priority: Issue #45 - Login failure"

Step 5: CI/CD Integration

// Monitor workflow runs
const workflows = await github.listWorkflowRuns({
  owner: 'user',
  repo: 'project',
  status: 'failure'
});

// Alert on failures
if (workflows.length > 0) {
  const report = analyzeFailures(workflows);
  notify(`🔴 ${workflows.length} workflow failures`);
}

Best Practices

  • Use fine-grained GitHub tokens with minimal permissions
  • Require human approval for merges
  • Log all automated actions
  • Set rate limits to avoid API throttling

Conclusion

Your OpenClaw agent can now assist with code reviews, reducing review time while maintaining code quality standards.
