Under the hood
Warning about calling untested connector tools from an Artifact page now tells Claude to check the tool's argument schema too
What
When an Artifact page calls a connector tool that hasn't had a successful call observed during the current session, Claude Code shows a warning about that. The warning message now adds a new instruction: check the page's argument names against each tool's input schema, if the session has access to that tool, and treat the result fields the page reads as unverified unless a real, safe call can confirm them.
Why
This gives Claude a concrete way to partially verify an untested tool call, by checking argument names against the schema, rather than treating every unverified call the same way.
