PowerShell.MCP v1.3.1 - Complete Stream Capture + Context Display Everywhere

Complete Stream Capture + Context Display Everywhere

This release delivers complete stream capture for all PowerShell output and extends context display from Show-TextFile to all file editing cmdlets. Zero breaking changes—just better reliability and visibility.

✨ What's New

🛡️ Complete Stream Capture

All PowerShell output streams (Success, Error, Warning, Info, Verbose, Debug) are now reliably captured. v1.3.0 could not capture Verbose and Debug streams, which is now fixed. This also eliminates duplicate error messages and ensures no output is lost.

🔍 Context Display for All File Operations

v1.3.0 introduced context display for Show-TextFile. Now all file editing cmdlets show context with 2 lines before/after each change:

# All of these now show context automatically
Update-MatchInFile config.json -Pattern "old" -Replacement "new"
Update-LinesInFile script.ps1 -LineRange 10,15 -Content $newCode
Add-LinesToFile functions.ps1 -LineNumber 42 -Content $newFunction
Remove-LinesFromFile old-code.cs -LineRange 100,200

Features:

• 2 lines of context before and after each change
• Grep-style formatting with visual highlighting
• Smart range merging for nearby changes
• Consistent formatting across all cmdlets
