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-watch tokens can be renewed in place, once the server allows it

Not switched on

Artifacts

Live artifact watches could refresh their connection token in place, but the server never says they can.

Token renewal for live artifact subscriptions is implemented but only runs when the server marks a subscription renewable, which nothing does.

What

A new call renews the token for an artifact's live update channel instead of tearing down and re-establishing the whole subscription. The client only takes that path when the subscribe response marks the subscription renewable, and nothing in the client sets that field, so the code ships inactive until the artifact service starts returning it.

Details
  • Renewal posts to /api/frame/watch-token/<slug>; a failure is reported as a renewal miss and the old re-subscribe path is used.

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