🔧 GitHub Workflow Automation
Patterns for automating GitHub workflows with AI assistance, inspired by Codex CLI and modern DevOps practices.
When to Use This Skill
Use this skill when:
- Automating PR reviews with AI
- Setting up issue triage automation
- Creating GitHub Actions workflows
- Integrating AI into CI/CD pipelines
- Automating Git operations (rebases, cherry-picks)
1. Automated PR Review
1.1 PR Review Action
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: ${{ secrets.ANTHROPIC_API_KEY }}
1.2 Review Comment Patterns
# AI Review Structure
## 📋 Summary
Brief description of what this PR does.
## ✅ What looks good
- Well-structured code
- Good test coverage
- Clear naming conventions
## ⚠️ Potential Issues
1. **Line 42**: Possible null pointer exception
```javascript
// Current
user.profile.name;
// Suggested
user?.profile?.name ?? "Unknown";
```
- Line 78: Consider error handling
💡 Suggestions
- Consider extracting the validation logic into a separate function
- Add JSDoc comments for public methods
🔒 Security Notes
- No sensitive data exposure detected
- API key handling looks correct
### 1.3 Focused Reviews
```yaml
# Review only specific file types
- name: Filter code files
run: |
files=$(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)\n\n"
fi
done
# Send to AI with full file context
