ChatGPT and Claude’s Hidden Instructions Are on GitHub

This GitHub repository documents system prompts and internal instruction formats associated with ChatGPT, Claude, Gemini, Grok, Perplexity, Copilot and other AI products.

System prompts are instructions loaded before a user's message. They can influence personality, tool usage, workflows, formatting, priorities and safety behavior.

The repository may include a mixture of officially published material, extracted prompts, reconstructed content and older versions. Individual files should be independently verified before being treated as authentic, complete or current.

For AI developers, the useful lesson is not copying private instructions—it is studying how production-grade assistants structure tool rules, task hierarchy, failure handling and consistent behavior.
