validating-pre-commit

The skill content is coherently aligned with its stated purpose of enforcing a pre-commit quality gate using standard developer tooling. Its data flows are largely confined to local project operations with minimal risk of credential exposure or external data exfiltration, provided users follow the documented safe usage of environment variables and do not commit real secrets into those examples. Overall risk is low to moderate (benign) with minor credential exposure considerations only if real secrets are mishandled in examples.
