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.
Stale prompt cancellation reports which tool calls it killed
Under the hood
Useful2Signal2
Elsewhere
On resume, cancelled leftover prompts are now reported by id to the headless loop.
What's wrong with this entry?
Anonymous. No account, no email.
What
On resume in headless and print mode, the routine that cancels permission and dialog prompts left over from a prior worker now returns the tool call ids it cancelled, and both callers pass that set into the headless streaming loop. It previously returned nothing.
Details
Which prompts get cancelled, and the telemetry emitted for it, are unchanged.
Evidence

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