Source Intelligence

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.

New cli_api_error event when API retries are exhausted

Under the hood
Useful2 Signal2
Telemetry

An API call that fails every retry now records attempts, timing, model and route.

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.

Evidence

did_fallback_to_non_streaming

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