# Arachne

> Use this tool when you need to efficiently navigate and search a project's codebase, as it indexes code into a local database and provides targeted context through a 4-layer system, supporting keyword and semantic searches across multiple programming languages. It solves problems of code discovery, dependency chain traversal, and information overload, providing a precise overview of project structure and relationships. Ideal for use in large-scale development projects where quick code lookup and understanding are crucial.

## Description

Indexes a project codebase into a local SQLite database and assembles precisely targeted context using a 4-layer system: project tree overview, current files, search results with dependency chain traversal, and frequently accessed files. Supports BM25 keyword search with optional semantic vector search via Ollama embeddings, and follows import chains across JavaScript, TypeScript, Python, Rust, Go, and Java. Achieves significant token reduction while maintaining accuracy through intelligent file selection.
