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.

Background-state reads retry before giving up

Background Tasks

Background state reads retry on transient errors instead of failing immediately.

What

Reads of background state now retry on a delay schedule while the error looks transient, so a momentarily unavailable read no longer surfaces as a failure.

Details
  • Retried when the error is Unavailable, or Failed but outside a known set of permanent failure classes.
  • A read that succeeded only after retries reports tengu_bg_state_read_recovered with the number of attempts; a clean first read is noted separately.
Evidence

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