Devs using Cursor/Copilot: How do you stop AI from hallucinating component props?

I've been building React apps with AI assistants for a while now, and my biggest frustration is "Context Hallucination."

You know the feeling: You ask Copilot to build a form, and it tries to use props that don't exist in your component library, or it imports components you haven't installed.

I'm curious how everyone is handling this right now:

• Do you copy-paste docs into the chat every time?

• Do you maintain massive .cursorrules files?

• Or do you just accept that you have to fix the AI's mistakes manually?

I’m currently working on a UI library that uses the Model Context Protocol (MCP) to "feed" the component docs directly to the AI.

Do you think "AI-Native" libraries are the future, or is prompting enough?
