Summary

ARE-bench preserves unfinished files, old decisions and failed attempts instead of evaluating agents in a clean room.

ARE-bench contains 75 tasks reconstructed from real researcher sessions and full in-progress workspaces across seven research stages. Its 1,173 binary checklist items include not only the immediate deliverable but also historical decisions and material workspace constraints. Across seven frontier models, the strongest passed every item on 66.2% of tasks. Three models passed about 69% when judged only on delivery contracts and general norms, but 28.4% to 40.0% when historical and workspace requirements were added, showing how clean-task evaluation can overstate reliability.
