Can I integrate this into my existing CI/CD workflow?

Yes, the skill is designed to be portable and includes examples for integration with Git pre-commit hooks and GitHub Actions workflows.

Can it detect if my script will work on different Linux distributions?

Yes, by using the portability check feature, it identifies 'bashisms' and ensures scripts adhere to POSIX standards for maximum cross-platform compatibility.

How does it help with script security?

It scans for dangerous patterns such as unquoted variables, unsafe use of eval, and potential command injection points that could be exploited in production.

What documentation is included with this skill?

It provides comprehensive references for Bash syntax, POSIX standards, ShellCheck error codes, and common text processing tools like awk, sed, and grep.

Does this skill require ShellCheck to be installed?

While the validator works best with ShellCheck, it includes an automatic wrapper that can install it via Python if missing, or perform basic syntax checks using native shell flags.
