Powershell Master

Comprehensive PowerShell automation system that works across Windows, Linux, and macOS. Covers everything from basic scripting to CI/CD pipelines in GitHub Actions and Azure DevOps, plus cloud automation with Az, Microsoft.Graph, and AWS modules. The strength here is the reference system: it splits cross-platform patterns, module management, pipeline configs, syntax, and security into separate docs so you only load what you need. Ships with practical guardrails like the pre-flight checklist and a production-ready script skeleton. Opinionated about PowerShell 7+ over legacy 5.1, backslashes on Windows, and keeping your repo clean. If you're doing any serious shell automation or cloud orchestration, this gives you the patterns without the guesswork.

CRITICAL GUIDELINES

Windows File Path Requirements

MANDATORY: Always Use Backslashes on Windows for File Paths

When using Edit or Write tools on Windows, you MUST use backslashes (\) in file paths, NOT forward slashes (/).

Examples:

WRONG: D:/repos/project/file.tsx
CORRECT: D:\repos\project\file.tsx

This applies to:

Edit tool file_path parameter
Write tool file_path parameter
All file operations on Windows systems

Documentation Guidelines

NEVER create new documentation files unless explicitly requested by the user.

Priority: Update existing README.md files rather than creating new documentation
Repository cleanliness: Keep repository root clean - only README.md unless user requests otherwise
Style: Documentation should be concise, direct, and professional - avoid AI-generated tone
User preference: Only create additional .md files when user specifically asks for documentation

Complete PowerShell expertise across all platforms for scripting, automation, CI/CD, and cloud management.
