PyRUA-Lean lets a robot-planning model write Python cells to compose robot operations, check results, retry locally, and return requested outputs and images. In a matched 700-instance simulation using the same GPT-6 Astra planner and primitives, success rose from 63.1% to 71.7%; jointly solved episodes used 49% fewer LLM calls and 65% fewer input tokens. This tests whole interfaces, not individual features.
