What it does

Once installed, the agent can advise on configuring ShellCheck, a static analysis tool that finds bugs and portability problems in shell scripts without running them. It explains ShellCheck error codes, how to suppress false positives with documented exclusions, how to set up linting in CI pipelines, pre-commit hooks and editors, and how to fix flagged issues. The skill's text is a guide; its only additional file, references/details.md, holds longer pattern documentation that the agent reads when needed.

Great for

  • Developers maintaining bash or sh scripts who want consistent linting in CI
  • Teams adding ShellCheck to a repository or pre-commit setup for the first time
  • Anyone trying to understand a specific ShellCheck warning code and how to fix it

Skip it if

  • Non-programmers who need to write shell scripts from scratch, since this skill focuses on checking and configuring rather than authoring
  • Projects that do not use shell scripts, where the skill has no use
  • Relying on it to guarantee script correctness: static analysis catches common pitfalls but not all logic errors

Try asking

  • “Set up ShellCheck in our GitHub Actions pipeline and explain how to fail the build on warnings”
  • “Why is ShellCheck flagging SC2086 in this deploy.sh, and how should I fix it?”
  • “Write a .shellcheckrc that targets POSIX sh and excludes SC1091 with a documented reason”
  • “Add a pre-commit hook that runs ShellCheck on staged shell files”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Paste the exact warning code and the surrounding lines so the agent can give a targeted fix rather than generic advice
  • Ask for each suppression to include a comment explaining why it is safe, as the skill recommends
  • Review any suggested CI changes before merging, since the agent cannot test them against your runner
