Create, edit, review, and harden GitHub Actions workflows using Bret Fisher's strongly opinionated DevOps rules. Use this skill whenever the user asks about GitHub Actions, GHA, workflow YAML, CI/CD pipelines, Docker image publishing, workflow security, action pinning, build caching, matrix builds, release automation, or `.github/workflows/*` files, even if they only ask for a small workflow change. This also compliments the "gasa" CLI tool which audits GitHub Actions workflows for security and best practices.
Set up local development linting by picking the right linters for each file type a project uses, then recording them as required pre-commit checks in AGENTS.md / CLAUDE.md and a `make lint` target. Uses the super-linter project as the live source of truth for which linters are current and popular per language. Use this skill whenever the user wants to add, choose, configure, or standardize linters for local development; asks "what linter should I use for X"; wants the agent to lint files before committing; sets up AGENTS.md/CLAUDE.md linting rules; or mentions super-linter, linting setup, pre-commit linting, or keeping linters up to date. This is for LOCAL developer/agent linting, not for authoring CI workflows.
Create, edit, and modernize Dockerfiles, .dockerignore, Docker Bake files, and Compose files using Bret Fisher's strongly opinionated modern Docker + BuildKit rules. Use this skill whenever the user asks about a Dockerfile, containerizing or "dockerizing" an app, base image choice, digest/SHA pinning of image tags, multi-stage builds, BuildKit, build caching or secrets, .dockerignore, docker-bake.hcl / `docker buildx bake`, hardened or distroless images (Chainguard, Docker Hardened Images / DHI), a compose.yaml / docker-compose file, or local dev environments with Compose — even for a small change to any of these files.
