What
The WebFetch tool has a special carve-out allowing it to fetch claude.ai artifact links using your logged-in claude.ai session. That carve-out now also matches the shorter URL form claude.ai/artifact/{id}, in addition to the longer claude.ai/code/artifact/{uuid} form it already covered.
Why
This means fetching a claude.ai artifact link via its shorter URL now benefits from the same authenticated access as the longer form, rather than being treated as an ordinary, unauthenticated fetch.
