About
This skill empowers Claude to generate production-grade shell scripts for both POSIX sh and Bash environments. It emphasizes defensive programming through fail-fast patterns, comprehensive cleanup using trap handlers, and sophisticated argument parsing. By integrating best practices for utility tools like jq and yq, and providing frameworks for testing with ShellCheck and Bats, it ensures that automation scripts, CI/CD pipelines, and container entrypoints are maintainable, secure, and portable across Linux and macOS systems.
