 3. Interact using refs (`click @ref`, `fill @ref "text"`)

 - Prefer `snapshot -i` to reduce output size.
 - On iOS, `xctest` is the default and does not require Accessibility permission.
 - If XCTest returns 0 nodes (foreground app changed), agent-device falls back to AX when available.
-- `open <app>` can be used within an existing session to switch apps and update the session bundle id.
+- `open <app|url>` can be used within an existing session to switch apps or open deep links.
+- `open <app>` updates session app bundle context; URL opens do not set an app bundle id.
 - If AX returns the Simulator window or empty tree, restart Simulator or use `--backend xctest`.
 - Use `--session <name>` for parallel sessions; avoid device contention.
-- Use `--activity <component>` on Android to launch a specific activity (e.g. TV apps with LEANBACK).
+- Use `--activity <component>` on Android to launch a specific activity (e.g. TV apps with LEANBACK); do not combine with URL opens.
+- iOS deep-link opens are simulator-only in v1.
 - Use `fill` when you want clear-then-type semantics.
 - Use `type` when you want to append/enter text without clearing.
 - On Android, prefer `fill` for important fields; it verifies entered text and retries once when IME reorders characters.
