Structured code reasoning is replacing pure text generation
Code agents are beginning to shift from “generate directly” to “build structure first, then generate.” The strongest signal comes from API evolution migration: KCoEvo uses a knowledge graph to explicitly represent cross-version relationships, then has the model generate code along migration paths, delivering large gains across multiple models on difficult version migration tasks. In parallel, patch correctness assessment also shows that graph-structured representations are more stable, suggesting that in code tasks, structured program information is replacing pure text prompts or ordinary retrieval as the main driver of reliability improvements.
