What this measures

Can an agent get things done on the web? It drives realistic clones of shopping, forum, and wiki sites to complete tasks like 'order the cheapest blue mug.' Measures tool-use and planning.

Sample
'Find the most-upvoted post in the r/books forum from last month and reply to it.' — judged by the final site state.
