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.

Groundwork for pre-warmed sessions claimed on demand

Under the hood
Useful2 Signal4
Cloud Sessions

Sessions can now register as spare and poll to claim one, pointing at sessions started before you need them.

Registration tracks and reports spare sessions and polls to claim them, but nothing in the build makes spare sessions reachable by default.

What

Session registration now tracks whether a session was created spare and polls to claim one, and reports itself as spare when registering. This points at sessions started ahead of time and handed out when needed. Nothing in this build shows spare-session creation being reachable by default, so whether any are made is decided elsewhere.

Details
  • The related lock that keeps one session's work from another now records whether it is bound to this specific machine.
  • A dedicated error type was added for two resume attempts racing each other.

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