claude-kb 0.1.0

Universal knowledge base with Qdrant for Claude Code integration

Claude KB

Universal knowledge base with Qdrant for Claude Code integration.

Provides semantic search across:

• Claude Code conversation history
• Personal knowledge entities
• Documents and research notes

Installation

Run directly (no install)

uvx claude-kb status

Install as a tool

uv tool install claude-kb
kb status

Development

git clone https://github.com/tenequm/claude-kb.git
cd claude-kb
uv sync --extra dev

Features

• Hybrid search: Dense (semantic) + sparse (keyword) vectors with RRF fusion
• Claude Code import: Automatically import your conversation history
• LLM-optimized CLI: kb ai command provides token-efficient schema for AI agents
• FastEmbed/ONNX: Fast local embeddings with bge-base-en-v1.5 (768 dim, ~1s search time)
• Self-hosted: Run locally with Docker Compose

Quick Start

# Start Qdrant
docker compose up -d

# Initialize collections
kb init

# Import your Claude Code conversations
kb import claude-code-chats

# Search!
kb search "qdrant vector databases"

Usage

Search conversations

kb search "your query"
kb search "query" --collection conversations --limit 20

Get specific message

kb get msg_abc123

Check status

kb status

LLM-optimized schema (for AI agents)

kb ai

This outputs a token-efficient format that Claude Code and other LLMs can parse to understand how to use the CLI. See docs/AI_COMMAND_SPEC.md for details.

Architecture

• Simplified structure: cli.py, core.py, import_claude.py (No manual embedding code!)
• Qdrant collections: conversations, entities, documents
• Embedding: QdrantClient built-in FastEmbed with BAAI/bge-base-en-v1.5 (768 dim, ONNX-optimized)
• Search time: ~1 second total (0.7s model load + 0.3s search)
• Output format: Structured plaintext (NOT JSON) optimized for LLM parsing

Configuration

Create .env file (see .env.example):

QDRANT_URL=http://localhost:6333
EMBEDDING_MODEL=BAAI/bge-base-en-v1.5  # FastEmbed model (768 dims, ~1s search)

# Alternative models:
# EMBEDDING_MODEL=BAAI/bge-small-en-v1.5  # Faster (384 dims, ~0.5s)
# EMBEDDING_MODEL=BAAI/bge-large-en-v1.5  # Higher quality (1024 dims, ~2s)

Development

# Format + lint
ruff format . && ruff check . --fix

# Test (manual for now)
uv run kb --help

Roadmap

• Streaming search (background mode)
• Entity management (kb add entity)
• Document import (kb add document)
• Relationship traversal (kb related)
• Full hybrid search (sparse vectors)
• Token-aware context window truncation
