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.

Cancelling tool calls now also cancels their queued follow-ups

Tool Execution

Cancelling a tool call now also cancels the follow-up work queued behind it.

What

Cancelling in-flight work now revokes the pending follow-up items attached to it, matched by the cancelled item's id or its note id, instead of leaving them queued to run.

Details
  • Follow-ups are revoked with an explicit "cancel" reason.
  • Unconditional.

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