Main's MegaLinter job invokes actionlint separately from pre-commit. The release workflow's valid GitHub background/wait steps were covered only by pre-commit's CLI exclusions, so main failed even though the PR checks passed.

Move the two compatibility exclusions into .github/actionlint.yaml, scoped to .github/workflows/release.yaml. Both MegaLinter and pre-commit now use native config discovery. Remove the broader hook-only arguments and run full-codebase MegaLinter on PRs as well as main so this entrypoint is checked before merge.

Keep the lint workflow token read-only and explicitly disable MegaLinter PR comments, which require write permissions. Results remain available in the Actions job output and summary.

Validation: reproduced the exact two actionlint failures on current main; the same bare actionlint invocation passes with the shared config; all pre-commit hooks pass. A negative fixture confirms an unrelated workflow with a missing command is still rejected. No release build or publication logic changes.

Summary by CodeRabbit

  • Chores
    • Improved workflow validation by running lint checks across all configured triggers and the full codebase.
    • Updated repository permissions for lint workflows to read-only access.
    • Refined action workflow linting to recognize supported syntax and configuration.
    • Disabled automated comment reporting from the MegaLinter.
    • Removed custom actionlint exceptions from the pre-commit configuration, allowing standard validation to apply to workflow files.

📝 Walkthrough

The change adds Actionlint configuration for the release workflow, removes selected Actionlint suppression arguments, and configures MegaLinter to validate the full codebase on all workflow-triggered runs.

Changes: Lint workflow and Actionlint configuration

.github/actionlint.yaml, .mega-linter.yml, prek.toml, .github/workflows/lint.yaml
Actionlint uses release-workflow configuration for selected diagnostics. The Actionlint hook no longer suppresses selected validation errors. MegaLinter runs on all configured workflow triggers, validates the full codebase, and has read-only repository contents permission.
