App replicasDomain expertsCoding and SWETool use
Idler builds RL environments from real production work. ShelfLife is a digital twin of a live e-commerce company with about 200 environments and a public leaderboard, and CorpLaw is built from a law firm’s anonymized data. Private collections cover long-horizon SWE, cybersecurity and terminal agents on request.
