Workflow Setup Skill

Set up GitHub Actions workflows for continuous integration and deployment.

When To Use

• Need CI/CD for a new project
• Adding missing workflows to existing project
• Updating workflow versions to latest
• Automating testing and quality checks
• Setting up deployment pipelines

When NOT To Use

• GitHub Actions workflows already configured and current
• Project uses different CI platform (GitLab CI, CircleCI, etc.)
• Not hosted on GitHub
• Use /attune:upgrade-project instead for updating existing workflows

Standard Workflows

Python Workflows

1. test.yml - Run pytest on push/PR
2. lint.yml - Run ruff linting
3. typecheck.yml - Run mypy type checking
4. publish.yml - Publish to PyPI on release

Rust Workflows

1. ci.yml - Combined test/lint/check workflow
2. release.yml - Build and publish releases

TypeScript Workflows

1. test.yml - Run Jest tests
2. lint.yml - Run ESLint
3. build.yml - Build for production
4. deploy.yml - Deploy to hosting (Vercel, Netlify, etc.)

Workflow

1. Check Existing Workflows

ls -la .github/workflows/

Verification: Run the command with --help flag to verify availability.

2. Identify Missing Workflows

from project_detector import ProjectDetector

detector = ProjectDetector(Path.cwd())
language = detector.detect_language()

required_workflows = {
    "python": ["test.yml", "lint.yml", "typecheck.yml"],
    "rust": ["ci.yml"],
    "typescript": ["test.yml", "lint.yml", "build.yml"],
}

missing = detector.get_missing_configurations(language)

Verification: Run pytest -v to verify tests pass.

3. Render Workflow Templates

workflows_dir = Path(".github/workflows")
workflows_dir.mkdir(parents=True, exist_ok=True)

for workflow in required_workflows[language]:
    template = templates_dir / language / "workflows" / f"{workflow}.template"
    output = workflows_dir / workflow
