Graft

Graft is an open-source tool that creates a graph-based map of your codebase, enabling AI coding agents like Claude Code, Cursor, and Codex to understand code structure without starting from scratch. It commits plain-English documentation to git and runs entirely locally with no embeddings or external dependencies.

The tool reduces latency by 60%, cuts tool calls by 46%, and lowers costs by up to 32% while maintaining or improving correctness. Setup takes two commands, and Graft automatically keeps the map in sync during development. It supports 20+ languages via Tree-sitter parsing and provides impact analysis to show a symbol's full blast radius before changes.
