airline

An executable Environment for tool-using agents, rebuilt from traces by Kullback and published by Leibler: the world, the Tasks and a code Verifier per Task, no recordings. tasks.jsonl lists the Tasks.

Release: replays at least 90% of its Tasks.


Fidelity over Tasks	100.0% (130 of 130)

Untrusted Tasks are not graded, and the simulated user does not ship, so a fetched package cannot finish a Task that needs a fact the user gives mid conversation, though the Task still carries a Verifier.
