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.

Preconnect skip rules replaced with a provider check

Under the hood
Useful1 Signal3
Internals

The startup warm-up request now skips based on your resolved provider rather than a list of variables.

What

The warm-up request to /api/hello no longer checks a list of provider environment variables such as Bedrock, Vertex, Foundry and Mantle. It now skips when the resolved provider is not first-party, when the login method is a gateway, and on one further condition whose meaning is not settled in this build. Proxy, unix socket and client certificate skips are unchanged.

Evidence

/api/hello

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