DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Artifact room messages and page verification now show up in the transcript

Artifacts

Artifact room messages and page verification now render readably instead of as raw tool calls.

What

Two artifact actions render properly instead of appearing as raw tool calls. room_send shows the topic, plus target and payload in verbose mode, and reports results such as "sent to N peers" or "not sent (reason)". verify reads back console diagnostics captured by a viewer's browser, with distinct wording for nothing captured, output truncated at a size cap, and a clean load.

Details
  • The clean case reads "loaded clean: zero diagnostics captured".
  • The watches summary now counts joined artifact rooms and shows connecting, registering and ended states separately.
  • Rendering is unconditional; whether the actions exist at all comes from the artifact tool's own schema.
Evidence

loaded clean: zero diagnostics captured

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
