What
When the artifact read action is given something that is not a URL (a web address), its error message now names the design tool if that tool is available. After publishing creates a typed artifact, Claude Code can also start an extra background step when a certain condition holds.
Why
The error now points to the design tool by name, so it is clearer what to use instead.

Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
