GitHub Actions Workflow Skill

Step 1 — Detect Project Type

Identify the runtime and package manager before scaffolding:

• Language (Go, TypeScript/Node, Python, PHP, …)
• Package manager (pnpm, npm, Go modules, uv, Composer)
• Test and lint commands (from justfile, Makefile, or package.json)
• Deploy targets (container registry, cloud provider, static host)

For pnpm 12 projects, do not install pnpm with Corepack. Bootstrap pnpm with npx get-pnpm next-12, the standalone installer, or the repository's existing approved setup action if it installs pnpm directly.

Step 2 — Scaffold .github/workflows/ci.yml
