ramybarsoum/prodkit/CLAUDE.md

This file is the schema layer of prodkit's knowledge system (inspired by Karpathy's LLM Wiki pattern). It tells the LLM how to maintain the user's product knowledge base and how skills interact with it. Two jobs: (1) define the three-layer knowledge architecture, and (2) encode 7 passive automations that make skills smarter across sessions. No setup required. Everything activates on first use.

CLAUDE.md vs AGENTS.md

About CLAUDE.md

What is CLAUDE.md?

A file Claude Code reads at the start of every session. It holds the commands, conventions and warnings the agent needs for this project.

Where does it go?

At the repository root. Claude Code also reads CLAUDE.md files in subdirectories when it works there.

What should it contain?

Build and test commands, the project's layout, conventions that aren't obvious from the code, and mistakes to avoid. Short files tend to work better than long ones.

CLAUDE.md or AGENTS.md?

Claude Code reads CLAUDE.md; most other agents read AGENTS.md. Many projects keep one and point the other at it.
