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.
Result output documents its pending-user-turn count
Under the hood
Useful2Signal2
Elsewhere
The result message documents exactly which queued sends its pending count includes.
What's wrong with this entry?
Anonymous. No account, no email.
What
The result message field counting queued sends now explains itself: it counts only your own sends still waiting when the result was produced, queued sends may merge together, entries the system queued are not counted, and the field is missing on results from a fatal startup failure.
Evidence
User-initiated sends still waiting in the command queue when this result was produced.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
