What is CLAUDE.md and how do I make one?

Touch CLAUDE.md in your project root. Fill with the five sections: overview, stack, conventions, do-nots, context. Claude Code auto-reads it.

Does CLAUDE.md work with other AI code tools like Cursor or Copilot?

Nope, Claude Code specific (Anthropic's extension). But copy the format—similar hacks exist for others via custom instructions.

No silver bullet. Fixes 80% drift, but complex logic still needs human eyes. Use it as guardrails, not autopilot.

🤖 Large Language Models

Claude's great—until it isn't. One markdown file at your repo root fixes the forgetfulness, forcing consistency across sessions. But does it stick?
