Separating specification from synthesis improves LLM code generation
A new research framework challenges how LLM agents approach program synthesis from scratch, where current methods fail on over 99% of tasks. The work separates behavioral specification elicitation as a distinct phase before code generation, drawing from classical software engineering practice. This addresses a critical gap in agent reasoning: existing end-to-end approaches conflate documentation parsing, behavioral exploration, and implementation, causing agents to misinterpret requirements early and propagate errors downstream. The insight matters for anyone building autonomous coding systems, as it suggests frontier models need structured exploration phases to ground their synthesis in actual system behavior rather than documentation alone.
