What

Claude Code used to carry a file called claude-code.d.ts packed inside itself. A file of this kind describes the shapes of data and functions for programming tools. It is no longer included.

Another bundled file, used for allowing tools, was also replaced with a different version.

Why

The type definitions are no longer shipped inside Claude Code. That could affect any feature that read them.
