> ⚠️ **Production Release (v2.5.56)**: Stable and actively maintained. LanceDB is now the default backend for better performance and stability.

A modern, fast, and intelligent code search tool that understands your codebase through semantic analysis and AST parsing. Built with Python, powered by LanceDB, and designed for developer productivity.

## ✨ Features

### 🚀 **Core Capabilities**
- **Semantic Search**: Find code by meaning, not just keywords
- **AST-Aware Parsing**: Understands code structure (functions, classes, methods)
- **Multi-Language Support**: 13 languages - Python, JavaScript, TypeScript, C#, Dart/Flutter, PHP, Ruby, Java, Go, Rust, HTML, and Markdown/Text (with extensible architecture)
- **Knowledge Graph**: Temporal knowledge graph with KuzuDB for entity extraction and relationship mapping (`kg build`, `kg status`, `kg query`)
- **Interactive Visualization**: D3.js-powered visualization with 5+ views (Treemap, Sunburst, Force Graph, Knowledge Graph, Heatmap)
- **Development Narratives**: Generate git history narratives with `story` command (markdown, JSON, HTML output)
- **Real-time Indexing**: File watching with automatic index updates
- **Automatic Version Tracking**: Smart reindexing on tool upgrades
- **Local-First**: Complete privacy with on-device processing
- **Zero Configuration**: Auto-detects project structure and languages

### 🛠️ **Developer Experience**
- **CLI-First Design**: Simple commands for immediate productivity
- **Rich Output**: Syntax highlighting, similarity scores, context
- **Fast Performance**: Sub-second search responses, efficient…
