# Cortex

> Use this tool when you need to efficiently navigate and understand complex codebases, and solve problems related to code discovery, documentation, and architecture. Cortex indexes code into structured entities, enabling semantic search, graph relationships, and incremental updates, and provides this context via JSON-RPC stdio. It is ideal for use cases where developers require a deeper understanding of their codebase, such as during onboarding, debugging, or refactoring.

## Description

Indexes codebases into structured entities (files, rules, ADRs) and exposes that context over JSON-RPC stdio. Provides semantic search across code and documentation, graph relationships between entities and architectural constraints, and incremental updates to keep context fresh as the repository changes. Works with Claude Code/Desktop and Codex clients.
