actions-lint-fix

Lint and fix reusable GitHub Actions by validating formatting, checking required keys like inputs and runs, and enforcing correct action versioning against YAML files in actions/**/*.yml or actions/**/*.yaml.

Validating GitHub Actions versioning and formatting requires yamllint, act, shellcheck, and jq to parse YAML structures, test execution logic, and enforce required keys while prohibiting root-level on and jobs.

Automatically correct invalid action version references in CI/CD pipelines by detecting unsupported versions like actions/checkout@v15 and suggesting stable alternatives such as @v6 or pinning to a specific SHA.

Required YAML keys for reusable GitHub Actions include name, description, inputs, and runs. The root of action definitions must prohibit on and jobs keys to ensure proper reusable action structure.

GitHub Actions linting applies specifically to reusable action definitions located at actions/**/*.yml or actions/**/*.yaml, targeting policy compliance and versioning security rather than linting general workflow YAML files.
