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.

Turn handling moved out of the REPL into the turn controller

Under the hood
Useful1 Signal1
Elsewhere

Turn handling moved out of the prompt loop into the turn controller with nothing changing on screen.

What

Work that lived in the interactive prompt loop now belongs to the turn object, with no change to what happens on screen.

Details
  • Moved: loading-state reset, spinner tip selection, session signal tracking (bash tools, hosts, tools used), rate-limit auto-continue arm/cancel/prefill/retract, initial message submission with the resume partial-output hint, and queued input execution.
  • Many separate references, including file-read state, session env vars, tool state, memory selection, isolation latch, content replacement, tool and MCP computation, dialog requests and sandbox verdicts, were collapsed into one scope object on the host.
  • The telemetry involved already existed in the previous build.
Evidence

prefillRateLimitAutoQueueContinue

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