Purpose
This tool is a Claude Code skill that provides templates, best practices, and live verification for developing PowerShell scripts, modules, and GUIs.

Security Assessment
The skill operates as a knowledge base and reference guide but includes capabilities that require user awareness. It executes PowerShell commands and scripts locally (such as `Search-Gallery.ps1`) and makes network requests to external sources like the PowerShell Gallery and Microsoft Learn documentation to verify module availability and cmdlet syntax. The automated scan flagged no dangerous permissions and found no hardcoded secrets. Because it is designed to generate and facilitate the execution of PowerShell code on the host machine, the overall risk is rated as Medium. Users should review any generated code before running it.

Quality Assessment
The project appears to be active and well-documented, with its last push occurring today. It enjoys a moderate level of community trust, evidenced by 21 GitHub stars. The repository includes a comprehensive README detailing installation, usage, and skill contents. There is a minor discrepancy regarding licensing: the README prominently displays an MIT license badge, but the automated health check failed to find a formal license file in the repository. The code scan was also incomplete due to unsupported source files, meaning a deeper manual review of the PowerShell scripts is advisable.

Verdict
Use with caution: the skill provides useful, actively maintained development guidance, but its ability to make network requests and execute local PowerShell scripts warrants a review of any generated code prior to execution.

PowerShell Expert Skill

License: MIT
Version
Platform
Claude Code

A Claude Code skill for developing PowerShell scripts, tools, modules, and GUIs following Microsoft best practices.

Features

  • Script Development - Templates, naming conventions, parameter design, pipeline patterns
  • GUI Development - Windows Forms and WPF/XAML patterns with 15+ control examples
  • PowerShell Gallery Integration - Search, install, and manage modules via PSResourceGet
  • Module Recommendations - Curated list of popular modules by category
  • Live Verification - Validates module availability and cmdlet syntax against live documentation

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 Type Source
Module exists/active PowerShell Gallery
Cmdlet syntax Microsoft Learn / raw GitHub docs
PSResourceGet cmdlets Raw GitHub markdown (deterministic URL)
Version requirements Gallery 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.
