What
The description text that tells Claude how and when to use the Claude Design tool was reworked.
- The opening paragraphs pitching Claude Design as the preferred tool for presentations, decks, and prototypes over local files or HTML artifacts were removed, leaving only the operational "what this tool can do" listing.
- New guidance was added distinguishing the collaborative Claude Design canvas (for decks/prototypes the user can co-edit live) from standalone Claude Design projects (to be used only when the user explicitly names or links one), and directs other deck/mockup requests to the Artifacts tool's Slides or Design Artifact types instead.
Why
This changes when Claude reaches for the Claude Design tool versus the Artifacts tool, aiming for a more accurate fit between the request (e.g. a quick mockup vs. a real-time collaborative deck) and the tool used to fulfill it, rather than always steering toward Claude Design.
