RevengeBench: Reverse Engineering Code-Space Policies from Behavioral Experiments

arXiv:2606.26094v1 Announce Type: new Abstract: For most of scientific history, researchers studying behavior could only infer hidden mechanisms from outward actions: an inverse problem that becomes more tractable when observation is augmented by targeted intervention. We pose a computational analogue: given only behavioral traces of an agent in a game environment, can a learner reconstruct the underlying decision program as executable code, and how much does this reconstruction improve with the ability to design controlled experiments? We introduce RevengeBench, a benchmark of 75 LLM generate

Why this matters
Why now

The proliferation of complex AI systems, particularly large language models, necessitates advanced methods to understand and reverse-engineer their decision-making processes.

Why it’s important

Understanding and reconstructing AI decision programs is crucial for debugging, auditing, security, and ensuring predictability and safety, especially as autonomous systems become more integrated into critical infrastructure.

What changes

The ability to reverse-engineer AI policies from behavioral experiments could lead to more robust, transparent, and controllable AI systems, moving beyond black-box analysis.
