--- title: "Context Substrate" type: concept tags: [ai-agent, memory, architecture] last_updated: 2026-04-23 --- ## Definition AI Agent 的上下文管理技术路线之一(Camp 2)。维护结构化、人类可读的上下文文件(Markdown、知识图谱、上下文容器),跨会话自然累积增长。 ## Core Philosophy **"What context should the AI work inside?"**(而非 Camp 1 的 "what should the AI remember?") - Nothing gets extracted — the context is the files. - 文件是人类可读、可编辑、可理解的。 - 因为上下文是文件,人可以随时纠正、补充和理解 Agent 知道什么。 - 系统随时间自然复合增长(compounding),而非依赖提取质量。 ## Mechanism ``` Agent reads structured context → Agent works within that context → Agent (or background process) writes back to the structured context → Next session, the context is richer than before ``` ## Representative Tools - [[OpenClaw]]:Markdown 文件 + dreaming cycle - [[Zep]]:Temporal knowledge graph(Graphiti) - [[Thoth]]:Personal knowledge graph(10 entity types, 67 relations) - [[TrustGraph]]:Context Cores(可移植版本化上下文捆绑包) - [[MemSearch]]:Markdown-first + shadow vector index - [[ALIVE]]:Structured context substrate, walnuts as portable containers ## Relationship to Camp 1 - Camp 1 优化目标:**召回**(can the system find the right fact?) - Camp 2 优化目标:**复合**(does the system get better over time?) - Zep 从"memory"→"context engineering"的品牌重塑,是 Camp 1/Camp 2 边界处最强的市场信号 - Supermemory(Camp 1)的时序感知和 Honcho(Camp 1)的心理建模,代表 Camp 1 向 Camp 2 的演进趋势 ## Key Distinction from RAG RAG 通常指一次性的文档检索问答场景;Context Substrate 强调**跨时间的上下文累积**,是持续运行 Agent 的基础设施。
