KnowledgeHub

KnowledgeHub 是面向本地多知识库的统一扫描、增量索引和 AI 检索基础设施。

它不搬运原始文件,而是注册多个知识目录,检测新增、修改和删除,更新本地 SQLite/FTS5 全文索引,并通过只读 MCP 同时向 Claude Code 和 Codex 提供带绝对路径、章节、行号和原文片段的检索能力。

当前状态

  • 实现版本:0.1.0
  • 运行时:Python 3.12
  • 项目目录:/Users/your-user/KnowledgeHub
  • 实际配置:config/knowledge-bases.yaml
  • 索引数据库:index/knowledge.db
  • 已启用知识库:daily-workbusiness-dev
  • 首次真实索引:2026-07-16,共 850 个文档、16,610 个 chunks
  • AI 接入:Claude Code 与 Codex 均已注册用户级/全局 knowledgehub MCP
  • 调度:macOS launchd 每天本地时间 12:00 执行 kb reconcile --all
  • 通知:复用本机 Lark 机器人脚本发送任务摘要

已实现能力

  • 多知识库、多根目录和 project_id 路由
  • Markdown、Text、YAML、JSON、HTML、PDF、DOCX 解析
  • SHA-256 增量检测与 Manifest 全量对账
  • SQLite WAL + FTS5 trigram 全文检索
  • 1–2 字中文查询 LIKE 回退
  • 显式 chunk_id 关联、scope/project 过滤
  • 解析失败保留最后一次成功索引
  • 敏感路径和敏感内容拒绝索引
  • 只读 MCP:kb_searchkb_readkb_project_contextkb_status
  • PID 锁、stale lock 恢复、当天成功去重、Lark 重试与 outbox

快速使用

cd /Users/your-user/KnowledgeHub

# 校验配置
.venv/bin/kb config validate --config config/knowledge-bases.yaml

# 快速增量扫描:不做全局删除对账
.venv/bin/kb scan --scope daily-work --config config/knowledge-bases.yaml

# 完整 Manifest 对账:每日任务使用此命令
.venv/bin/kb reconcile --all --config config/knowledge-bases.yaml

# 全文检索
.venv/bin/kb search "半双工消息流" --scope daily-work --config config/knowledge-bases.yaml

# 项目知识路由
.venv/bin/kb project-context /Users/your-user/workspace/bit-news \
  --config config/knowledge-bases.yaml

# 查看健康状态
.venv/bin/kb status --json --config config/knowledge-bases.yaml

安全边界

  • Indexer 不修改、不删除、不移动原始知识文件。
  • MCP 只提供读取和检索,不提供写入/删除工具。
  • .env、私钥、证书、Token、凭据文件默认拒绝索引。
  • Lark Webhook 或应用凭据保留在项目目录外,不复制进 KnowledgeHub。
