DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Design error classes relocated in the bundle

Under the hood
Useful1 Signal1
Claude Design

Design auth error types moved, joined by a new precondition error and response shapes.

What

The Claude Design authentication error types moved to the top level of the bundle with their wording and the design_tool_auth_401 code intact, joined there by a new precondition error and the response shapes for the project read, search, write, delete and info calls. Whether the consent and project-grant error types were re-declared elsewhere is not visible in this build.

Evidence

design_tool_auth_401

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
