Installation

Copy the skill folder to your Claude Code skills directory:

cp -r powershell-expert ~/.claude/skills/

Or unzip the packaged skill:

unzip powershell-expert.skill -d ~/.claude/skills/

Usage

The skill activates automatically when you ask Claude Code to:

  • Write PowerShell scripts or functions
  • Create Windows Forms or WPF GUIs
  • Find or recommend PowerShell modules
  • Follow PowerShell best practices

Example Prompts

"Write a PowerShell script to monitor disk space"
"Create a GUI for selecting and renaming files"
"What module should I use for working with Excel files?"
"Help me add proper error handling to this script"

Live Verification

When accuracy is critical, the skill verifies information against live sources:

Verification TypeSource
Module exists/activePowerShell Gallery
Cmdlet syntaxMicrosoft Learn / raw GitHub docs
PSResourceGet cmdletsRaw GitHub markdown (deterministic URL)
Version requirementsGallery metadata

Module recommendations are always verified before being presented. If live verification fails, the skill falls back to executing Search-Gallery.ps1 locally or prompts the user to verify manually.
