DART: Semantic Recoverability for Structured Tool Agents
Researchers have introduced DART, a new runtime system designed to improve the reliability of structured tool agents, particularly in commitment-sensitive scenarios. DART addresses the challenge of recovering from agent failures when downstream systems have already acted on the agent's output. It achieves this by certifying semantically recoverable boundaries, aligning checkpoints, and selecting admissible restore points to preserve downstream work, thereby preventing data inconsistencies that simpler rollback methods might miss.
