Explain a PowerShell script line by line

Overview
SCRIPT EXPLAINER
This tool does not run or send your code anywhere. It identifies common PowerShell structures and explains the role they play.
Line-by-line view
READ BEFORE YOU RUN
What the script explainer helps you inspect
Use it when you inherit a script and need a first-pass map of what the code is doing before you execute it.
Commands and pipelines
Identify cmdlets, pipeline stages and common control-flow patterns. Follow the data from the source command through filters, transforms and output instead of reading the file as one block of text.
Variables and decisions
Look for variables, loops, conditions and places where external state may change the result. Then verify unfamiliar commands with Get-Help and inspect objects with Get-Member .
The explainer does not execute uploaded code and cannot prove that a script is safe. Treat it as a learning aid, then review modules, credentials, file paths and state-changing commands yourself.
Review your script
Text-based review hints only. This does not execute or fully validate PowerShell.
