# system-prompts-and-models-of-ai-tools

> Repository of extracted system prompts and tools from major AI assistants.

This repository documents leaked and reverse-engineered system prompts, tool schemas, and model configurations from commercial AI tools like Cursor, Lovable, v0, Devin, and Windsurf. It helps developers understand how top AI editors structure interaction rules, XML tags, and file operations. You can study these prompts to design AI products or adapt them into local project rules like Cursor MDC files.
