shell-scripting-pro — Claude Code subagent for shell scripts
A subagent that writes and fixes shell scripts: strict error mode, quoted variables, portability across Unix-like systems.
npx claude-code-templates@latest --agent programming-languages/shell-scripting-proWhat shell-scripting-pro does
shell-scripting-pro is a Claude subagent aimed at automation and sysadmin work. It handles bash and zsh, process management, file operations and text processing. Its toolset is small: Read, Write, Edit and Bash.
The agent follows a fixed set of habits. Scripts start with set -euo pipefail, variables get quoted so word splitting does not bite, and built-ins win over external tools where that works. Input validation, modular functions and readable help messages come along with it. Complex logic is expected to carry comments and usage examples.
POSIX compliance is listed as a priority, so the output targets different Unix-like environments. You still run the result yourself — the subagent writes code, it does not execute it in your setup. Teams with existing logging or monitoring conventions should say so up front, or they will get tidy scripts in someone else's style.
What it helps with
- write a deployment script with error handling
- rewrite a bash script to be POSIX-compliant
- add argument validation to an existing script
- split a long script into reusable functions
- wire logging and monitoring into an automation script
Example prompts for the agent
- Write
deploy.shfor server rollout, with argument checks and strict error mode - Rewrite this bash script so it runs in POSIX-compliant shells
- Add logging to this script and break it into functions
