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.

What
An API call that fails after all retries now emits an error-level telemetry event recording the attempt count, the duration with and without retries, whether it fell back to non-streaming, the client request id, the model, the query source and the route.

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