A file of this kind describes the shapes of data and functions for programming tools. It is no longer included.\n\nAnother bundled file, used for allowing tools, was also replaced with a different version.\n\n**Why**\n\nThe type definitions are no longer shipped inside Claude Code. That could affect any feature that read them.\n\n- Area: SDK\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: yes"}
