The System Prompts & Models of AI Tools repository by x1xhlol is one of the most comprehensive open-source collections of AI system prompts, internal tool instructions, and LLM model configurations available today. Featuring over 30,000 lines of real-world prompt architectures, this project offers developers unprecedented insights into how leading AI tools—including Cursor, Devin AI, Claude Code, Replit, Poke, NotionAI, Perplexity, Warp.dev, Windsurf, Trae, Qoder, Z.ai Code, and many others—design their agents, copilots, workflows, and coding assistants.
Updated frequently and supported by a large community of AI engineers, this repository is a goldmine for anyone studying prompt engineering, agent orchestration, multi-tool collaboration, LLM behavior, or how AI development environments are built internally. It includes system prompts, role prompts, mode-switching logic, editor prompts, browser/terminal agents, reasoning instructions, memory structures, and more.
Whether you’re building your own AI agent, improving an AI-powered development tool, researching LLM security, or designing workflow automation systems, this dataset provides real, proven examples from top AI platforms—something rarely accessible to the public.
This is not just a resource—it’s a blueprint for understanding and building next-generation AI systems.
