What probably matters to youSection of the release
What
When a first-party connector for reading and writing documents (Claude Docs) is attached, the artifacts flow now routes document creation to that connector or its skill instead of creating an Artifact, falling back to the normal quickstart flow otherwise.
A validation rule that used to block the auto_open: "after_first_write" option under a certain tool-availability condition has been removed from artifact publishing.
The instructions Claude sees when starting a new Artifact now explicitly say auto_open: "after_first_write" should never be used for a type whose content is written through a connector, such as a Claude Docs document.
The description of the auto_open parameter on the artifact-creation tool was simplified, dropping an extra sentence that used to appear only when a certain feature flag was on.
Why
This avoids opening an artifact automatically for content that is actually being created through a connector like Claude Docs, keeping the auto-open behavior consistent with where the content is really going.
