Working Directory Detection

MANDATORY: ALWAYS detect and navigate to solution root automatically in ALL PowerShell scripts; NEVER assume correct working directory; ALWAYS use Set-CorrectWorkingDirectory or similar.

• Check .sln files OR (src/ + .github/) combo to identify solution root
• Walk up to 5 levels
• Test common paths (../../, .., ../../../../)
• Visual feedback on navigation

function Set-CorrectWorkingDirectory {
    $current = Get-Location
    for ($i = 0; $i -lt 5; $i++) {
        if (Test-Path "*.sln" -or (Test-Path "src" -and Test-Path ".github")) {
            Write-Host "Solution root found: $PWD" -ForegroundColor Green
            return
        }
        Set-Location ".."
    }
    throw "Could not find solution root"
}

Path Safety

• ALWAYS use Test-Path before Set-Location
• Resolve-Path to validate
• Join-Path for building paths
• Avoid hardcoded absolute paths
• Use relative paths from solution root

if (Test-Path $targetPath) {
    $resolvedPath = Resolve-Path $targetPath
    Set-Location $resolvedPath
}

Error Handling

• try/catch for critical ops
• Meaningful error messages
• Appropriate exit codes (0=success, 1=failure)
• Write-Error for critical
• Write-Warning for warnings

try {
    Set-CorrectWorkingDirectory
} catch {
    Write-Error "Failed to find solution root: $_"
    exit 1
}

AI Guidance

Include directory navigation notes in responses that involve PowerShell scripts; explain root detection briefly; do not assume user is in correct directory; show navigation commands when relevant.

Script Structure

• param block first
• Helper functions for navigation
• Validation before execution
• Cleanup in finally blocks
• Structured output with colors

Execution Policies

Use -ExecutionPolicy Bypass when needed; document requirements; handle security restrictions; provide alternatives.

Cross-Platform

Correct path separators; consider case sensitivity; handle different PS versions; test on Windows/Linux when applicable.
