mex vs Graft

mex: mex provides persistent, navigable project memory for AI coding agents, allowing every session to start with the right context instead of a cold prompt. It structures agent memory through a markdown scaffold, offers CLI tools for drift detection against the real codebase, and synchronizes context to keep agents aligned and reduce token usage.; Graft: Graft is an open-source context layer designed to accelerate and optimize coding agents like Claude Code, Cursor, and Gemini by providing deep contextual understanding of large codebases. It builds a human-readable code graph and linked markdown nodes, enabling agents to operate faster, cheaper, and with higher correctness by avoiding repeated code exploration.

Features

mex logomex
01Creates a structured markdown scaffold for AI agent memory (e.g., AGENTS.md, ROUTER.md, context/, patterns/).
02CLI tools for drift detection, validating scaffold against the actual codebase without using AI tokens.
03Automatically generates targeted prompts for AI agents to fix stale or broken context.
04Supports task-specific context routing, loading only relevant files for the current task.
05Includes an append-only event log to store decisions, notes, risks, and todos.
Graft logoGraft
01Generates a human-readable, linked markdown graph of the codebase for contextual understanding.
02Provides real explanations of system parts and their connections, bypassing redundant agent exploration.
03Automatically refreshes the code graph against the working tree for real-time accuracy, even with uncommitted edits.
04Supports multiple LLM providers for generating summaries, allowing users to use their preferred models and keys.
05Acts as a local, regenerable cache (`graft/` folder) that is not committed to version control.
