+# PowerShell Token Optimization
+
+- **Use Short Aliases:** Use short aliases instead of full cmdlet names to drastically cut output tokens:
+  - Use `gc` instead of `Get-Content`
+  - Use `gci` instead of `Get-ChildItem`
+  - Use `%` instead of `ForEach-Object`
+  - Use `?` instead of `Where-Object`
+  - Use `measure` instead of `Measure-Object`
+- **Pipeline Over Loops:** Prefer pipeline chains (`gci | % { ... }`) over multi-line `foreach ($item in $items) { ... }` blocks.
+- **No Help/Comments:** Do not generate `.SYNOPSIS`, `.DESCRIPTION`, or comment-based help at the top of scripts.
+- **Omit Parameter Names:** Drop explicit parameter names where positional arguments are clear (e.g., use `gc file.txt` instead of `Get-Content -Path file.txt`).
+- **Silent Execution:** Do not add verbose logging, `Write-Host`, or `Write-Output` unless explicitly asked to create UI/logs.
+- **Preserve CLI Arguments:** Do not duplicate full multi-line `yt-dlp` command-line arguments, format strings, or output templates if they are not the subject of the modifications. Use placeholders or variable references.
