What is awesome-ai-system-prompts?

This repository is a collection of system prompts from popular AI tools, paired with a guide explaining how those prompts are structured and why certain patterns work. A system prompt is the hidden set of instructions that shapes how an AI assistant behaves before a user ever types anything. Tools like ChatGPT, Claude, Vercel's v0, Manus, and others all rely on carefully written system prompts to define their personality, capabilities, and limits. The main README doubles as an educational document. It walks through eight recurring principles found in well-designed agentic system prompts: defining the AI's role clearly, organizing instructions with structure, describing tools and when to use them, encouraging step-by-step reasoning, making the AI aware of its environment, constraining it to a specific domain, setting safety boundaries, and establishing a consistent tone. Each principle comes with direct excerpts from real prompts in the collection so readers can see concrete examples rather than abstract advice. The target audience is people building AI-powered tools or agents, sometimes called prompt engineers. If you are wiring up an AI model to perform tasks automatically and you want to understand how established products configure their AI, this repository gives you both the raw materials and a framework for thinking about them. Beyond the guide, the repository stores the actual prompt files for systems like Claude, ChatGPT, Cline, Bolt, Windsurf, Notion, and others. These are organized by product name so they can be read and compared side by side. The full README is longer than what was shown.
