MAGS: multi-agent auto-formalization provides formal safety guarantees for agentic code
The paper introduces MAGS, a multi-agent framework that auto-formalizes LLM-generated programs into Dafny, repairs verifier-detected violations, and compiles verified code back to executables. Evaluated on 100 CUDA kernels, 100 terminal scripts, and 20 robotic-arm tasks (220 examples), MAGS produced programs with machine-checkable safety guarantees against frozen specifications in all cases, while noting failures when the auto-formalized semantics did not fully capture intended behavior.
KEY POINTS
- The paper introduces MAGS, a multi-agent framework that auto-formalizes LLM-generated programs into Dafny, repairs verifier-detected violations, and compiles verified code back to executables.
- Evaluated on 100 CUDA kernels, 100 terminal scripts, and 20 robotic-arm tasks (220 examples), MAGS produced programs with machine-checkable safety guarantees against frozen specifications in all cases, while noting failures when the auto-formalized semantics did not fully capture intended behavior.
- This provides a practical, partially automated path to machine-checkable safety guarantees for code produced by LLM agents, reducing manual proof engineering and improving trustworthiness of agentic outputs.
