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.

A single-agent event reader was added for resumed cloud sessions

Under the hood
Useful1 Signal2
Cloud Sessions

Resumed cloud sessions gained a reader that pages events for a single subagent.

What

The cloud client gained a third way to read session events, alongside the whole-session and all-subagents readers: it pages the worker's event feed filtered to one agent id. It is only supplied when the session is a resume, and nothing else is passed otherwise.

Details
  • Unlike the other two readers it accepts a cancellation signal, threaded into both the network request and the retry backoff sleep, and bails out immediately if the signal is already aborted.
  • Its retry cap is 3 attempts rather than the general 10.
  • No feature flag guards it. What causes a single-agent read to be requested lives in the component the reader is handed to, which is not part of this change.

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