Someone leaked the full system prompts of every major AI tool in one GitHub repo.
You can now see exactly how they built:
→ Cursor, Devin AI, Windsurf, Claude Code, Replit
→ v0, Lovable, Manus, Warp, Perplexity, Notion AI
→ 30,000+ lines of hidden instructions exposed
→ The exact rules, tools, and personas behind each product
