app_sms

This tool on every surface: CLI · MCP · Python · JavaScript · Go · Java · .NET

Deliver a simulated text message, to see what an app does when one arrives mid-flow. Emulator only, for the same reason as app_call. Discards the refs from the last app_map.

Changes the device, the app or the session: readOnlyHint is false.
