bash-patch-safe

To validate a Bash script after a patch, run this skill to execute syntax validation using `bash -n`, detect duplicate function definitions, and confirm essential entry points like `main "$@"` remain present and correctly ordered.

Bash scripts break after manual edits when function definitions are unintentionally removed, function calls are disrupted, or duplicate functions are introduced, leading to runtime errors that are difficult to detect without validation checks.

You can verify immediate `--help` execution by running this validation skill, which enforces checks to ensure the script properly exits when invoked with the `--help` option alongside performing standard Bash syntax validation.

No, this Bash script validation does not require external dependencies, as it enforces checks like duplicate function detection, syntax validation, and entry point verification using only standard Bash utilities.

The best way to prevent duplicate function definitions is to run this validation skill after modifying your Bash scripts, which actively detects duplicates and verifies that functions remain defined, called, and correctly ordered.
