Problem Statement

Windows 11 is shipped with Powershell 5.1 by default. Claude Code defaulting to Powershell 7.x when using Powershell tool writes scripts that are not portable (especially for RMM software).

I write a lot of powershell scripts that have to be portable and usable with RMM software. I have tried to use Powershell tool by setting it as default one (instead of bash) and it caused many problems, most importantly - scripts lost compatibility and portability.

I have run adversarial agents that test both versions and general resolution was: more problems than solutions.

PS 7.x is not compatible with PS 5.1, these are totally different technologies. Different data folders, module paths, different credential stores.

I always ask Claude Code to do research and find edge cases of tool usage deliberately, find places where Claude is not sure then test them then write skills for them. Claude admitted - PS 7.x is very bad for portability.

Proposed Solution

1. Implement compatibility with 5.1 (that is default on Windows 11)
2. Add option to choose which version of Powershell we want to use 5.1 or 7.x.
3. Maybe default to 5.1 not 7.x at least until Microsoft switches to 7.x as default one.
