[davemc50]

Summary

• add a PowerShell script at scripts/install-cursor-agent-cli-windows.ps1
• script installs Cursor Agent CLI on Windows using Cursor's official installer URL
• includes basic safety checks (Windows-only guard, empty payload check) and verifies installation with agent --version

Usage

Run in PowerShell:

powershell -ExecutionPolicy Bypass -File .\scripts\install-cursor-agent-cli-windows.ps1

Optional custom URL:

powershell -ExecutionPolicy Bypass -File .\scripts\install-cursor-agent-cli-windows.ps1 -InstallUrl "https://cursor.com/install?win32=true"

Testing

• not executed in this Linux cloud environment (script is Windows-specific)
• static validation completed by reviewing script logic and PowerShell compatibility handling
