Key points
- This is the follow up to our first blog post, The Agent Said It Was Done.
- We built ThinkingBox to evaluate an agent's work by comparing the final database state with the expected outcome.
- ThinkingBox turns executable checks of terminal database state into rewards for post-training agents on tasks outside ThinkingBox-Bench.
- So we constructed a training pool from ThinkingBox-format tasks outside the benchmark and used their executable outcomes as rewards.
