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 watches can be woken by a turn instead of streaming

Not switched on
Useful2 Signal4
Artifacts

A watch can register a wake-up instead of streaming, waking your session when the artifact publishes.

Durable wake watch results and a registration-failure message are present under off-by-default artifact gating.

What

A watch can come back marked as a durable wake, meaning no live updates arrive and the session is instead woken by a new turn the next time the artifact is published, with instructions to re-read the artifact on wake. A separate message covers the case where that durable subscription could not be registered.

Details
  • Nothing in this build requests this mode; it applies only when the server returns it for a watch.
Evidence

this session will be woken by a new turn when the artifact is next published; no live updates are streamed, so re-read the artifact on wake.

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