What it is

AskUserQuestion now logs detailed completion stats and shows a transcript line for itself again

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.269.

Presence across releases

0

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

First cited

1

The earliest release whose published evidence quoted tengu_ask_user_question_completed was v2.1.269, 11 Sep 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table above.

Gate readings

0

No release here has a gate table behind it for this flag. Most published releases have none at all: the readings exist only for versions the pipeline captured flag state on.
