PolicyGuide: From Guarding One Action to Guiding the Whole Workflow for Policy-Compliant LLM Agents
PolicyGuide turns policy rules into workflow graphs so an agent is steered through required steps, not just blocked at risky actions.
The paper says customer-service agents fail both by taking forbidden actions and by skipping required procedures like identification or confirmation. PolicyGuide checks at user-turn boundaries, tracks graph state, and returns step-specific remediation toward a compliant path. In τ²-bench tests across airline, retail, and telecom domains, it raises mean Pass⁴ from 0.42 to 0.62, with the biggest gain in telecom. The same workflows transfer to Claude Sonnet 4.6 and Gemini 2.5 Pro agents. HF Daily Papers' note
