mex vs ditto
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.; ditto: Ditto is a tool that analyzes your past AI agent coding sessions to automatically create a personalized working profile. This profile helps AI agents understand your specific work habits, design preferences, and writing style, making them act more like you.

TL;DR
mexMemory & Context · ★ 1.8k
When to choose:
- Your AGENTS.md or CLAUDE.md has grown too big and you want a small anchor plus routed context files.
- You want memory as plain markdown in the repo, reviewable in pull requests and diffable.
- You want drift checks that run without AI tokens and flag missing paths, stale files and broken scripts.
When to skip:
- You want recall across unrelated projects or conversations; mex lives inside one repository.
- You have a small project: another set of files to maintain may cost more than it saves.
- You expect the AST code-graph feature today: the README marks it as an unreleased preview.

Features
mex01Creates 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.
ditto01Mines real coding-agent session logs (e.g., Claude Code, Codex, Copilot CLI) to extract implicit user behaviors.
02Generates a private, local working profile (`you.md`) that AI agents read before every task.
03Distinguishes and loads separate layers for work, design, and writing profiles based on the task.
04Ensures privacy by processing logs locally with best-effort redaction of secrets.
05Renders a shareable 'profile card' summarizing key laws and traits.

Use Cases
mex↳Maintaining consistent project context for AI coding agents across multiple sessions.
↳Significantly reducing token consumption in LLM interactions by providing only relevant context.
↳Onboarding new AI agents or developers to complex codebases with structured, up-to-date project knowledge.
↳Developing persistent AI agents for operational environments (homelab scenarios, system administration) with structured memory.
↳Automating the detection and correction of documentation or contextual drift from the actual codebase.
ditto↳Customize AI agents to understand your definition of 'done,' preferred debugging methods, and UI design principles.
↳Improve agent communication to match your actual working voice and avoid repetitive explanations.
↳Enhance agent rejections to align with what you typically reject on sight (e.g., 'fix the one thing,' not rewriting).
↳Develop a consistent persona for multi-agent systems without explicitly writing down all rules.
