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.

Retry classifier labels errors that carry a type but no status

Under the hood
Useful2 Signal2
Elsewhere

Errors hidden inside a successful response now get their own retry label instead of being unclassified.

What

Errors returned inside an otherwise successful response, which have an error type but no HTTP status, now get their own label built from an in_band_ prefix plus the error type. This branch runs before the existing server error and modified-thinking-blocks cases.

Evidence

thinking_blocks_modified

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