Graft - Context layer for coding agents

Show HN: Graft – Claude Code hooks that cut grep tokens by 42%

Graft is an open-source context layer that builds a persistent, markdown-based graph of your codebase, enabling coding agents like Claude Code, Cursor, Codex, and Gemini to work faster and cheaper. By pre-computing a semantic map of your code, Graft reduces token usage by up to 42%, cuts tool calls by 46%, and speeds up tasks by 60%, while improving correctness on SWE-bench Verified by 12 points. It integrates seamlessly via hooks and an MCP server, supports multiple languages, and requires no daemon or external services—just files in your repo.
