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.

Live room events always need a human approval

Useful3 Signal4
Artifacts

Broadcasting a live event to artifact viewers always asks you first, no exceptions.

What

The room_send action, which broadcasts a live, non-persisted event to everyone currently viewing a published artifact, cannot be auto-approved under any configuration. It is refused in plan mode, refused in a Cowork session with no way to show an approval card, and otherwise raised as an ask prompt that no always-allow rule can satisfy.

Details
  • Plan mode refusal reads "Live room events cannot be sent from plan mode".
  • Without a consent surface the Cowork refusal points you at the approval card.
  • The ask permission sets suppression of always-allow rules, and the automatic permission classifier is explicitly barred from approving it.
  • Inputs are validated: a lowercase topic name, and a JSON object payload under a size cap. Delivery and peer counts come back to the model as the tool result.

Live room events cannot be sent from plan mode

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