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.

Tool telemetry records how far into a call an interruption arrived

Under the hood
Useful2 Signal2
Telemetry

Interrupted tool calls now report how long they'd been running when you cancelled.

What

Every tool call now watches for cancellation and reports how long it had been running when the abort came in, on both the success and error events.

Details
  • The value is durationMsAtAbort; if the call was already cancelled when it was dispatched, the abort time is the start time, giving zero.
  • Recent-activity records gained the time they were recorded and the tool use id.
Evidence

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