setup-github-actions

What this skill does

Generates a GitHub Actions CI workflow tuned to your project. Detects your package manager (npm, yarn, pnpm, bun), test runner, and linter, and writes a workflow with dependency caching, parallel jobs for lint, typecheck, and test, and PR-only triggers. Optional preview-deploy and release jobs are scaffolded as commented blocks.

Use cases

• Adding CI to a fresh repo in one shot
• Speeding up an existing slow CI pipeline with caching
• Standardising CI across many repos in an org
• Catching lint and type errors before merge
