Perceive Before Reasoning: A Pre-Reasoning Perception Framework for Efficient and Reliable Proactive Mobile Agents

In three linesTwo-stage framework (PRPF) for proactive mobile agents decouples perception (deciding when to intervene) from reasoning (how to assist). Lightweight perceptor gates false triggers and compresses context, activating the MLLM reasoner only when needed. Reduces false trigger rates and improves efficiency on ProactiveMobile benchmark.
