Shell Scripts is a production-ready Claude Code skill (quality score 70/100) in the dev-shells sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/shell-scripts/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when writing or reviewing Bash scripts and shell snippets, especially for shebang selection, quoting, parameter expansion ("${VAR}" style), test expressions ([ ] vs [[ ]]), ShellCheck-guided fixes, and portability decisions across POSIX sh, Bash, and zsh compatibility targets.
The Shell Scripts skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It is part of the open ClaudSkills registry, a community-curated catalog of 15,000+ capabilities you can install for Claude Code — the Claude CLI agent.
