New benchmark reveals AI agent decomposition harms policy compliance

A new benchmark called Fiducia-bench has been developed to evaluate the governability of financial AI agents, specifically their adherence to policies like Know Your Customer (KYC) and Anti-Money Laundering (AML). The research indicates that decomposing an AI agent into smaller components can significantly degrade its policy compliance. This degradation occurs because facts relevant to policy decisions are attenuated at the boundary between components, leading to issues like under-escalation or over-escalation of actions. The study found that a 32B open-weights model lost up to 85% of discovered facts in a decomposed architecture, while a more capable GPT-4.1 mini model showed less severe attenuation, suggesting model capability plays a role in mitigating these governance costs.

    Governance at the Boundary: How Agent Decomposition Degrades Policy Compliance

    arXiv:2608.16055v1 Announce Type: new Abstract: Existing agent benchmarks ask whether the agent finished the task. We ask whether it finished it within policy. We introduce Fiducia-bench, a benchmark for the governability of financial agents---whether they escalate when obligated…
