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.

Engine controller subscribes to dialogs, thinking and now-priority commands

Under the hood
Useful3 Signal3
Session Loop

The engine pauses during blocking dialogs and aborts your turn when a command must run now.

What

Binding the engine to a host now pauses it while a blocking dialog is open, mirrors the thinking toggle into the thinking-token budget (zero when off), keeps the engine model in step with the host's main-loop model, and aborts the in-flight turn when a queued command is marked as needing to run now. It also merges salvaged continuation text into displayed message content.

Evidence

_abortOnNowPriorityCommand

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