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

• test.yml - Run pytest on push/PR

• lint.yml - Run ruff linting

• typecheck.yml - Run mypy type checking

• publish.yml - Publish to PyPI on release

Rust Workflows

• ci.yml - Combined test/lint/check workflow

• release.yml - Build and publish releases

TypeScript Workflows

• test.yml - Run Jest tests

• lint.yml - Run ESLint

• build.yml - Build for production

• 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

engine.render_file(template, output)
print(f"✓ Created: {output}")

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

4. Validate Workflows

Syntax check (requires act or gh CLI)

gh workflow list

Or manually check YAML syntax

python3 -c "import yaml; yaml.safe_load(open('.github/workflows/test.yml'))"

Verification: Run pytest -v to verify tests pass.

Workflow Best Practices

Use Latest Action Versions

Good - pinned to major version

• uses: actions/checkout@v4
• uses: actions/setup-python@v5

Avoid - unpinned or outdated

• uses: actions/checkout@v2
• uses: actions/setup-python@latest

Verification: Run pytest -v to verify tests pass.

Matrix Testing (Python)

strategy: matrix: python-version: ["3.10", "3.11", "3.12"] os: [ubuntu-latest, macos-latest, windows-latest]

Verification: Run pytest -v to verify tests pass.

Caching Dependencies

• uses: actions/setup-python@v5 with: python-version: '3.10' cache: 'pip' # Cache pip dependencies

Verification: Run python --version to verify Python environment.

Shell Script Safety in Workflows

When writing inline shell scripts in workflows, ensure proper exit code handling:

BAD - pipeline masks exit code

• run: | make typecheck 2>&1 | grep -v "^make[" echo "Typecheck passed" # Runs even if make failed!

GOOD - use pipefail

• run: | set -eo pipefail make typecheck 2>&1 | grep -v "^make["

GOOD - capture exit code explicitly

• run: | output=$(make typecheck 2>&1) || exit_code=$? echo "$output" | grep -v "^make[" || true exit ${exit_code:-0}

For complex wrapper scripts, run /pensive:shell-review before integrating.

Updating Workflows

To update workflows to latest versions:

/attune:upgrade-project --component workflows

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

Troubleshooting

Common Issues

Command not found Ensure all dependencies are installed and in PATH

Permission errors Check file permissions and run with appropriate privileges

Unexpected behavior Enable verbose logging with --verbose flag
