Automated PR Review ### 1.1 PR Review Action ```yaml # .github/workflows/ai-review.yml name: AI Code Review on: pull_request: types: [opened, synchronize] jobs: review: runs-on: ubuntu-latest permissions: contents: read pull-requests: write steps: - uses: actions/checkout@v4 with: fetch-depth: 0 - name: Get changed files id: changed run: | files=$(git diff --name-only origin/${{ github.base_ref }}...HEAD) echo "files<<EOF" >> $GITHUB_OUTPUT echo "$files" >> $GITHUB_OUTPUT echo "EOF" >> $GITHUB_OUTPUT - name: Get diff id: diff run: | diff=$(git diff origin/${{ github.base_ref }}...HEAD) echo "diff<<EOF" >> $GITHUB_OUTPUT echo "$diff" >> $GITHUB_OUTPUT echo "EOF" >> $GITHUB_OUTPUT - name: AI Review uses: actions/github-script@v7 with: script: | const { Anthropic } = require('@anthropic-ai/sdk'); const client = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY }); const response = await client.messages.create({ model: "claude-3-sonnet-20240229", max_tokens: 4096, messages: [{ role: "user", content: `Review this PR diff and provide feedback: Changed files: ${{ steps.changed.outputs.files }} Diff: ${{ steps.diff.outputs.diff }} Provide: 1. Summary of changes 2. Potential issues or bugs 3. Suggestions for improvement 4. Security concerns if any Format as GitHub markdown.` }] }); await github.rest.pulls.createReview({ owner: context.repo.owner, repo: context.repo.repo, pull_number: context.issue.number, body: response.content[0].text, event: 'COMMENT' }); env: ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }} ``` ### 1.2 Review Comment Patterns ````markdown # AI Review Structure ## 📋 Summary Brief description of what this PR does. ## ✅ What looks good - Well-structured code - Good test coverage - Clear naming conventions ## ⚠️ Potential Issues 1. **Line 42**: Possible null pointer exception ```javascript // Current user.profile.name; // Suggested user?.profile?.name ?? "Unknown"; ``` ```` 2. **Line 78**: Consider error handling ```javascript // Add try-catch or .catch() ``` ## 💡 Suggestions - Consider extracting the validation logic into a separate function - Add JSDoc comments for public methods ## 🔒 Security Notes - No sensitive data exposure detected - API key handling looks correct ```` ### 1.3 Focused Reviews ```yaml # Review only specific file types - name: Filter code files run: | files=$(git diff --name-only origin/${{ github.base_ref }}...HEAD | grep -E '.(ts|tsx|js|jsx|py|go)$' || true) echo "code_files=$files" >> $GITHUB_OUTPUT # Review with context - name: AI Review with context run: | # Include relevant context files context="" for file in ${{ steps.changed.outputs.files }}; do if [[ -f "$file" ]]; then context+="=== $file ===n$(cat $file)nn" fi done # Send to AI with full file context ```` --- ## 2.
