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.

Claude Code v2.1.251

Auto mode can now grant artifact room joins on its own

In auto mode, Claude can join an artifact's live room itself unless you refused before.

auto
What

Consent to join an artifact's live room, previously only a yes or no you gave, can now be recorded as granted by the automatic permission classifier. That grant holds only while the session stays in auto permission mode, and a refusal or a manual stop you made earlier keeps the classifier from auto-joining that room again.

Details
  • Consent is stored per room with the value classifier alongside the existing true/false.
  • The check requires the mode to be auto and the room not to have been stopped by the user.
  • Bookkeeping tracks whether the room was asked about, refused by the user, and stopped by the user.
  • A sweep detects when a classifier grant is no longer valid, leaves the room and clears the stored consent.
