你的 AI Agent 需要一个「三层记忆」,而不是一个聊天记录
Manoir Yantai · 2026-06-23 · via DEV Community

Manoir Yantai

去年我开始给 Hermes Agent 搞知识库。最初的想法很简单:装个向量数据库,查资料时能命中就行。结果跑了一圈发现——纯向量检索在 Agent 场景下不够用

有些记忆是你能精确描述的("帮我查上次那篇讲 gbrain 孤页的文章"),有些记忆你只记得个大概("有个关于知识图谱的……"),有些记忆你甚至不知道你该知道什么("我有哪些笔记是没关联起来的?")。一个检索策略覆盖不了这三种场景。

这就是 Knowledge-and-Memory-Management v0.0.2 解决的问题。

三层不是为了「多」,而是为了互补

项目是目前运行在 Hermes Agent 生态里的扩展层,底座是 hermes-memory-installer 提供的 gbrain(知识图谱)+ Hindsight(向量记忆)。KMM 在这上面加了四组模块:采集、笔记/RAG、云盘同步、知识增广。

其中最有工程价值的设计是三层跨层召回

FTS5 全文搜索  →  精确命中,知道你要什么
Hindsight 向量语义  →  模糊配匹,关键词不够时靠语义
gbrain 知识图谱  →  关系探索,你不知道但相关的节点

lightweight_recall.py 把这三级串联成一条管线——先查本地 SQLite FTS5,命中直接返回;没命中走 Hindsight 的文本嵌入匹配;还不满意就用 gbrain 展开知识图谱的邻接节点。

代码在 $AGENT_HOME/scripts/lightweight_recall.py,调用并不复杂:

# 三层召回示例
from knowledge_collector.knowledge_management import KnowledgeManager

km = KnowledgeManager()

# 一次调用,三级自动回退
results = km.tiered_search(
    query="Agent 记忆系统设计",
    tiers=["fts5", "hindsight", "gbrain"],
    limit_per_tier=5
)

for tier, hits in results.items():
    print(f"[{tier}] {len(hits)} 条结果")
    for h in hits[:2]:
        print(f"{h['title']} ({h['relevance']:.2f})")

FTS5 走 SQLite 内置,零依赖;Hindsight 端口 8890;gbrain 端口 8787。每层都是独立的可降级——向量服务挂了,全文搜索照样能跑。

真正干活的是这 40+ 工具

三层召回是检索层,采集层才是让知识库有东西可喂的入口。项目塞了 40+ 采集分析工具,按类型分:

  • 网页采集(9 引擎):Scrapling 做反检测,Crawl4AI 做智能路由,爬公众号不走弯路
  • 视频采集(12 工具):yt-dlp 拖流 → Whisper ASR 转写 → PaddleOCR 关键帧,抖音/YouTube 一把抓
  • 文档分析(9 工具):SenseNova 三件套(PDF/PPT/Word)处理扫描件和复杂排版
  • 书籍精炼(6 工具)book_to_skill 管线把 PDF/EPUB 拆成结构化 Skill + KMM 笔记

每周日凌晨还有个 knowledge_discovery.py 爬起来,扫 OneDrive 上的新笔记,自动录入 gbrain,顺便跑孤页链接修复——这些属于「你不需要知道它存在,但它让系统不腐烂」的基建。

几个工程取舍

  • 不做纯向量优先:FTS5 第一级是因为延迟低(毫秒级),且精确关键词匹配在查代码、查配置时远好于语义
  • gbrain 孤页处理是刚需:知识图谱不加链接维护,三个月后 90% 的页面都成孤岛(亲测 10,666 页从 1,716 个孤页降到 33)
  • 采集优先于检索:没有好的采集管线,检索再强也是对着空库跑——项目把采集工具堆到 40+ 不是炫技

适用场景

如果你的 Agent 需要从多个来源(网页、视频、文档、公众号)持续摄入知识,并且知识需要在精确搜索、模糊回忆和关系探索三个维度上都能命中——三层模式值得一试。不需要全部部署,只接 FTS5 + gbrain 两层也能跑,每层独立可降级。
