Unclear It is not stated what turns these features on or whether anything uses them yet.

What

Two pieces of groundwork appear:

  • Voice-call records: transcripts from a voice call are marked as not coming from you. Claude is told to treat them as untrusted background that never shows what you want.
  • MCP App views: a tool reads the current state that an MCP App view has shared, picked out by its widget_id. An MCP App is an interactive view supplied by an MCP server, an outside program that gives Claude extra tools.
Why

This prepares for voice-call and MCP App features, with protection built in against text in a call trying to give Claude instructions.
