COMPASS: Cognitive MCTS-Guided Process Alignment for Safe Search Agents

arXiv:2605.30838v1 Announce Type: new Abstract: LLM-powered search agents enable multi-step reasoning and tool use. However, these capabilities introduce retrieval-induced safety degradation, as harmful intents may decompose into seemingly innocuous sub-queries that lead to unsafe outcomes. Existing alignment methods struggle to capture sparse safety signals and fail to supervise diverse violations across multi-step interactions. We propose COMPASS, a Cognitive MCTS-Guided Process Alignment framework designed to achieve robust safety alignment throughout the agent workflow while preserving gen

Why this matters
Why now

As LLM-powered search agents become more sophisticated, the challenge of 'retrieval-induced safety degradation' becomes a pressing concern, necessitating advanced alignment methods.

Why it’s important

This work directly addresses a critical safety and reliability bottleneck for autonomous AI agents, determining their trustworthiness and broad deployability.
