About:
Action-validator is a static analysis tool designed to catch syntax errors and common mistakes in GitHub Actions workflow files and reusable actions before they are pushed. It validates YAML structure and checks against the GitHub Actions schema to ensure your CI/CD configurations are correct. This helps prevent runtime failures and reduces debugging time in your development pipeline.
Key Features:
  • Validates GitHub Actions workflows and actions YAML files
  • Checks for syntax errors and schema compliance
  • Fast static analysis without needing to run the actions
  • Command-line interface for easy integration into CI/CD
Use Cases:
  • Pre-commit hook to validate workflows before pushing
  • CI pipeline step to ensure workflow correctness
  • Debugging existing workflow configuration files
Alternatives:
  • actionlint – More feature-rich with additional linting rules, but action-validator is focused specifically on schema validation
  • yamllint – General YAML linter that doesn't understand GitHub Actions specific syntax and schemas
