Project history and usage

actionlint is a static checker for GitHub Actions workflow files. It matters in CLI package culture because it brought fast local linting, expression checks, action input validation, and CI-friendly diagnostics to a workflow format that many repositories otherwise validate only after pushing.

Project history

The rhysd/actionlint repository was created on 2021-05-25. Its README presents the tool as a static checker for GitHub Actions workflow files with syntax checks, expression type checks, action input/output checks, reusable workflow checks, ShellCheck and pyflakes integrations, and security checks.

The first GitHub release, v1.0.0, was published on 2021-06-16. The project continued as a Go command-line tool with install, usage, configuration, API, and reference documentation.

Adoption history

actionlint was packaged broadly across developer distributions. The supplied package-manager facts list apk, Homebrew, MacPorts, Nix, pacman, Scoop, and winget, matching the official installation documentation's emphasis on released binaries, Homebrew, go install, Docker, and integrations.

GitHub repository metadata showed nearly 4,000 stars by June 2026, a strong adoption signal for a specialized workflow linter.

How it is used

The common local workflow is simply running actionlint at the repository root so it auto-detects workflow files. Optional configuration files live at .github/actionlint.yaml or .github/actionlint.yml, mainly for self-hosted runner labels, repository variables, and path-specific ignores.

Why package nerds care

Package maintainers care about actionlint because it packages a fast, self-contained static analysis tool for a file format used by a huge share of open source projects. It also bridges ecosystems by integrating ShellCheck, pyflakes, reviewdog, pre-commit, editor tooling, Docker images, and GitHub Actions itself.
