What

Claude Code has a new comparison that looks at two versions of a changing schema (the description of what something accepts) and labels the difference as equal, a text-only change, the saved version offering more, the live version adding things, or something else. A function named prompt.compose was also added.

Why

This looks like a way to record how tool descriptions drift over time.
