HexaShell provides robot-coding agents reusable perception, motion-checking, and error-reporting tools, with task-specific knowledge in reviewed natural-language skills. On RoboDojo, its GPT-6-Astra setup without skills achieved a 69.9% macro success rate, versus 22.5% for another agent using the same model. The comparison uses different agents and protocols, so it does not isolate which system component accounts for the gap.
