An AI skill for PowerShell and Bash scripting that writes, reviews and hardens shell scripts for backups, file cleanup, log rotation, user and service admin, scheduled jobs and CI steps. Every script gets parameter validation, a dry-run mode (-WhatIf or --dry-run), logging, exit codes, proper error handling and safe quoting, plus a test plan and a cron, systemd or Task Scheduler snippet.For sysadmins, developers and IT generalists on Linux, macOS and Windows. It never runs or suggests destructive commands without a dry run and confirmation, never hard-codes secrets and never claims a script was tested. Unlike Rami - DevOps Engineer, who covers infrastructure and CI broadly, or Cordelia - Zapier & Make Automation Specialist, who works no-code, this skill goes deep on the script itself.Writes shell scripts you can safely run at 2 a.m.: validated, dry-run first, logged and easy to schedule.Compatible with: Claude, Claude Code, ChatGPT, Gemini and Copilot. Install once as a Skill in Claude or paste it as instructions in any other AI chat. Does it handle both Windows and Linux? Yes - Bash on Linux, macOS and WSL, and both Windows PowerShell 5.1 and PowerShell 7+. Can it fix my existing script? Yes - review mode returns a findings table with line, issue, severity and fix, then a corrected version. Will it run the script for me? No - you run it; it gives a safe dry-run command and the expected output first. Can it convert Bash to PowerShell? Yes - and it notes behavior that does not translate one-to-one.
