powershell-windows

powershell-windows is an agent skill that lists critical patterns and pitfalls for Windows PowerShell. Its first rule concerns operator syntax. When logical operators join cmdlet calls, each cmdlet call must be in its own parentheses, otherwise PowerShell reads the expression differently from what you intended. The skill gives examples of the wrong and right forms, such as a test of two paths joined with an or operator, and then a test of a file's existence combined with a value comparison. It also covers error handling and the other syntax rules that trip up people who move from other shells. Use it when writing or fixing a PowerShell script on Windows, especially one that uses conditions, pipelines or error handling.
