Action Summary

The Nervous System Check GitHub Action enforces governance rules in CI pipelines by scanning pull requests for modifications to a configurable list of protected files. It automates the detection of unauthorized changes, failing the check and posting detailed violation reports as PR comments when protected files are altered. This ensures compliance with repository policies and safeguards critical files from unintended modifications.
