Claude Island installs PowerShell hook scripts into %HOMEPATH%\.claude\hooks and registers them in %HOMEPATH%\.claude\settings.json. These hooks fire on Claude Code events (tool use, permission requests, session start/end, etc.) and communicate with the app via a Windows Named Pipe (\\.\pipe\claude-island).

The app listens for events and displays session state in the overlay panel. When Claude needs permission to run a tool, the overlay expands with approve/deny buttons — no need to switch to the terminal.

Claude Code → Hook Event → PowerShell Script → Named Pipe → Claude Island → UI
