Tray & window behavior

Sentinel is a tray-only app — there’s no Dock icon. The tray icon lives in your menu bar (macOS) or system tray (Windows/Linux).

Showing and hiding the window

• Click the tray icon to open the window.
• Closing the window with the red ⨉ (or ⌘W) hides it — the background daemon keeps running so Claude Code can keep routing through it.
• To fully quit, use the ⋯ menu → Quit Sentinel, or the tray menu → Quit Sentinel.

The ⋯ menu

The in-app overflow (⋯) menu offers:

• Live daemon pid and uptime.
• Uninstall Sentinel… (with an option to also delete local data).
• Quit Sentinel.

Window sizing

The window is pinned to a compact, non-resizable size for tray-menu ergonomics. The exception is when DevTools is open (see below), where the window temporarily grows to give the inspector room.

The dev badge

The footer carries a dev version badge that toggles the platform’s native web inspector docked inside the Sentinel window — Safari Web Inspector on macOS, Edge DevTools on Windows, WebKitGTK Inspector on Linux. Click it to open, click again to close. The window grows while the inspector is docked and restores its tray size when you close it. See Debugging for what each inspector gives you.

Launch at login

Controlled by the launchAtLogin setting (default on) — see the Settings reference.
