Shellcheck Configuration

This is your reference guide for setting up and configuring ShellCheck across projects and pipelines. It covers the practical stuff: writing .shellcheckrc files, understanding common error codes like SC2086 and SC2181, suppressing false positives, and integrating with CI/CD systems like GitHub Actions and GitLab. The skill walks through actual configuration examples for different scenarios, from strict POSIX compliance to relaxed Bash development environments. Use it when you're hardening shell scripts, setting up pre-commit hooks, or need to quickly decode what ShellCheck is complaining about. The error code reference alone saves time hunting through documentation.
