Action — shellcheck

Runs ShellCheck on all .sh files in the repository.

Usage

steps:
  - uses: actions/checkout@v7

  - uses: KevinDeBenedetti/github-workflows/.github/actions/shellcheck@main
    with:
      severity: warning

Inputs

Input	Type	Default	Description
severity	string	warning	Minimum severity level: error | warning | info | style
exclude-paths	string	*/test_helper/*	Glob passed to find -not -path to exclude from analysis
default-shell	string	bash	Dialect for scripts with neither a supported shebang nor a # shellcheck shell= directive

Notes

• Finds all *.sh files recursively under the current directory (excluding exclude-paths, and never descending into .git, node_modules or .venv).
• Each script is checked as the shell its shebang (or # shellcheck shell= directive) declares, so #!/bin/sh scripts get POSIX checks; only undeclared scripts, and scripts whose shebang names a shell ShellCheck does not support (zsh, fish…), fall back to default-shell.
• Reports issues in GCC format for clean integration with GitHub annotations.
• Installs a pinned ShellCheck release (x86_64 or aarch64) — nothing needs to be preinstalled on the runner.
