AppWorld-UL (Code Agent) - Compositional 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 210 tasks combining several interaction types with a ReAct code agent; higher is better.

Metric: Interactive task goal completion (%; share of 210 tasks combining two or three interaction types whose AppWorld unit tests all pass, including a test that the agent asked the simulated user for every piece of hidden information it needed; ReAct code agent that writes Python against the AppWorld app APIs; GPT-5.5 user simulator answering from a fixed knowledge set).
