2. Create a GitHub Actions Workflow File (.github/workflows/claude-review.yml):

name: Claude Code Review

on:
  pull_request:
    types: [opened, synchronize, reopened]

jobs:
  review:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4
        with:
          fetch-depth: 0 # Fetch all history for better context

      - name: Get Changed Files
        id: changed_files
        run: | 
          FILES=$(git diff --name-only --diff-filter=d HEAD~1...HEAD)
          echo "::set-output name=files::${FILES}"

      - name: Run Claude Code Review
        uses: actions/github-script@v7
        with:
          script: |
            const fs = require('fs');
            const claudeApiKey = process.env.CLAUDE_API_KEY;
            const changedFiles = process.env.CHANGED_FILES.split('\n').filter(f => f.endsWith('.py') || f.endsWith('.js')); // Example: only review Python/JS

            if (changedFiles.length === 0) {
              console.log('No relevant files changed. Skipping Claude review.');
              return;
            }

            let reviewComments = '';
            for (const file of changedFiles) {
              const fileContent = fs.readFileSync(file, 'utf-8');
              // In a real scenario, you'd use the Anthropic API here
              // For demonstration, we'll simulate a response
              const simulatedReview = `// Claude Code Review for ${file}\n// Potential issue found: Missing docstring. Please add a docstring explaining the function's purpose.\n// Suggestion: Improve variable naming for clarity.`;
              reviewComments += `
### File: ${file}
${simulatedReview}
`;
            }

            // In a real integration, you'd call the Anthropic API here
            // For example:
            /*
            const { Anthropic } = require('anthropic');
            const anthropic = new Anthropic({ apiKey: claudeApiKey });
            const prompt = `Review the following code changes for potential issues, security vulnerabilities, and adherence to best practices. Provide constructive feedback for each file.\n\nCode:\n---\n${changedFiles.map(f => `File: ${f}\nContent:\n${fs.readFileSync(f, 'utf-8')}`).join('\n\n---\n')}\n---`;
            const response = await anthropic.messages.create({
              model: 'claude-3-opus-20240229', // Or your preferred model
              max_tokens: 1024,
              messages: [{ role: 'user', content: prompt }]
            });
            reviewComments = response.content[0].text;
            */

            if (reviewComments) {
              await github.rest.issues.createComment({
                owner: context.repo.owner,
                repo: context.repo.repo,
                issue_number: context.issue.number,
                body: `**Claude Code Review Findings:**\n${reviewComments}`
              });
            } else {
              console.log('Claude Code found no issues.');
            }
        env:
          CLAUDE_API_KEY: ${{ secrets.CLAUDE_API_KEY }}
          CHANGED_FILES: ${{ steps.changed_files.outputs.files }}

Explanation:

The workflow triggers on pull_request events.
It checks out the code and identifies changed files.
The github-script step (simulating the actual Claude API call) processes these files. In a production setup, you would replace the simulation with actual calls to the Anthropic API using their SDK. You can find more details on prompt engineering for Claude at Mastering Prompt Engineering Claude: Beyond GPT-Centric Strategies for 2026.
If issues are found, Claude Code posts a comment on the pull request. This provides immediate feedback to developers.

This Claude Code GitHub Actions integration is a prime example of how AI enhances developer workflow AI by automating crucial quality gates.
