history
Project history and usage
action-validator is a standalone linter for GitHub Actions and workflow YAML files, checking structure against schemas and validating path globs.
Project history
The repository was created in October 2021 and published v0.1.0 the same day. The README describes a focused Rust-based tool intended for pre-commit hooks and similar validation workflows.
Adoption history
The official README documents several distribution paths: pre-built binaries from GitHub releases, cargo, asdf, mise, npm packages, direct repository builds, GitHub Action usage, and pre-commit integration. That spread is unusually broad for a small validator and reflects demand across Rust, Node, version-manager, and CI users.
How it is used
The core workflow is to pass one or more GitHub workflow or action YAML files to action-validator. The README also shows pre-commit hook usage, npx usage, a Node API, and running the validator inside GitHub Actions.
Why package nerds care
action-validator is package-nerd friendly because it packages a CI correctness check as a local command, not only as hosted platform behavior. It is also notable for offering the same validation idea through native binaries, cargo, npm, asdf, mise, pre-commit, and a composite GitHub Action.
