Under the hood
Artifact tool's 'read' action now documents which claude.ai link formats it supports
What
The description of the publish/read/list artifact tool's 'read' action now spells out that it accepts any claude.ai artifact link, in either the claude.ai/artifact/{id} or claude.ai/code/artifact/{uuid} format, and explicitly tells Claude to read these links using this tool action rather than WebFetch or curl.
Why
This steers Claude toward using the correct, more reliable tool for reading artifact links instead of general-purpose web fetching, which likely wouldn't handle them properly.
