让个人AI工具像协奏曲一样联动，靠共享状态实现无缝协同。
PSI: Shared State as the Missing Layer for Coherent AI-Generated Instruments in Personal AI Agents
- 用共享上下文总线统一各AI模块的状态与操作接口。
- 三周自用测试显示新工具可自动接入已有系统，无需手动配置。
- 适合构建一体化个人智能助手的开发者或极客用户。
个人AI工具如今可通过自然语言生成，但生成后往往彼此孤立。本文提出PSI，一种共享状态架构，将独立生成的模块转化为持久、互联且支持对话的协同工具，可通过图形界面和通用聊天代理访问。通过向共享个人上下文总线发布当前状态与可写回操作，各模块实现跨模块推理与多界面同步操作。我们在自研的个人AI环境中进行了为期三周的自述式部署，结果表明后期生成的工具可自动通过相同契约集成。PSI揭示了共享状态是将零散的AI生成软件转变为连贯个人计算环境所缺失的关键系统层。
原文摘要 · Abstract (English)
Personal AI tools can now be generated from natural-language requests, but they often remain isolated after creation. We present PSI, a shared-state architecture that turns independently generated modules into coherent instruments: persistent, connected, and chat-complementary artifacts accessible through both GUIs and a generic chat agent. By publishing current state and write-back affordances to a shared personal-context bus, modules enable cross-module reasoning and synchronized actions across interfaces. We study PSI through a three-week autobiographical deployment in a self-developed personal AI environment and show that later-generated instruments can be integrated automatically through the same contract. PSI identifies shared state as the missing systems layer that transforms AI-generated personal software from isolated apps into coherent personal computing environments.
