A solid choice if you're working with PowerShell 7+ across different operating systems and want Claude to understand the modern syntax. It covers the new parallel processing features, pipeline chain operators, ternary expressions, and SSH remoting that distinguish PowerShell Core from the older Windows-only version. The skill has decent traction with 204 installs and comes from a repo with 76 stars, though it throws warnings on a couple security audits. Best for automation scripts that need to run on Linux or macOS, or if you're refactoring legacy PowerShell to use the newer language features. It's specific enough to be useful without being overly niche.
