What this skill tells your AI

The instructions your AI receives, as published by jonreid/mastermind in .claude/skills/writing-bash-scripts/SKILL.md and read by ahel’s review.

Use #!/usr/bin/env bash as shebang
Always use set -euo pipefail for safety
Keep scripts minimal: no unnecessary comments or echoes
Minimal input validation; print usage to stderr and exit if inputs are missing/invalid
Don't check for installed commands if failure is obvious on use
Make script executable: chmod +x <script>
Prefer concise, direct logic over verbosity
