What

When Claude Code reads an artifact whose page it has already probed as a live document, the successful read result now has an extra note appended describing your local working copy.

Details
  • Applies only after a successful read (HTTP 200), and only when the live-document module is present and reports the page as a probed live doc.
  • The note text is fetched asynchronously and appended to the read result; without the module or the probe, the read result is unchanged.
