# Kai

> Use this tool when you need to analyze and understand the structure and behavior of a codebase, and solve problems such as identifying dependencies, tracking changes, and optimizing test coverage. It provides structured access to a codebase's semantic graph through 12 tools, covering tasks like symbol listing and impact analysis. Ideal for use cases where AI coding assistants require comprehensive insights into codebase semantics, across multiple programming languages.

## Description

Gives AI coding assistants structured access to a codebase's semantic graph through 12 tools covering symbol listing, caller/callee analysis, dependency tracking, test coverage mapping, semantic diffs, and impact analysis. Built on Kai's semantic engine that understands function signatures, call graphs, and behavioral changes across five programming languages. The graph initializes lazily on first use and supports selective CI optimization based on behavioral impact rather than file diffs.
