AppWorld-UL (Function Calling) - Confirmation Tasks: leaderboard

AppWorld-UL (2026) turns AppWorld test-challenge scenarios into user-in-the-loop tasks that are infeasible, underspecified or need confirmation, so an agent succeeds only if it also asks, informs or confirms with a simulated user. Interactive task goal completion in percent on the 102 confirmation-requiring tasks with a function-calling agent; higher is better.

Metric: Interactive task goal completion (%; share of 102 tasks whose actions need explicit user confirmation first whose AppWorld unit tests all pass, including a test that the agent asked the simulated user for every piece of hidden information it needed; function-calling agent over the AppWorld app APIs; GPT-5.5 user simulator answering from a fixed knowledge set).
