Bash Script Validator

Overview

This skill validates Bash and POSIX shell scripts with layered checks:

1. Syntax validation (bash -n or sh -n)
2. ShellCheck static analysis (system binary or wrapper fallback)
3. Custom security, portability, and optimization checks

Use the default flow below, then branch to fallbacks only when the environment is constrained.

Trigger Guidance

Use this skill when the request includes script quality, linting, syntax checking, or shell portability work.
