Lists on-screen windows of any app with window_id, owning app bundle id + name, title, bounds (global space, top-left, points), display_id (the CGDirectDisplayID — matches list_displays, so you can look up which display a window is on), and is_focused. Window TITLES require Screen Recording permission — without it this returns an explicit permission_required error rather than a title-less result. Optional app_bundle_id filter — note that Electron-style apps often own their windows from a HELPER process with a different bundle id, so a filter can come back empty while the app is plainly on screen. on_screen_only DEFAULTS TO TRUE and excludes minimized, hidden and other-Space windows; pass false to see them. When the result is empty this tool returns a `note` explaining which filter emptied it and what to pass instead — read it instead of concluding the app has no windows. window_id is stable within the session for later targeting.
