Extracted system prompts from Anthropic - Claude Fable 5, Opus 5, Claude Design, Claude Code. OpenAI - ChatGPT GPT-5.6-Sol, Codex. Google - Gemini 3.5 Flash, 3.1 Pro, Antigravity. xAI - Grok, Cursor, Copilot, VS Code, Perplexity, and more. Updated regularly.
This repository collects and archives extracted system prompts from major AI assistants, updated regularly as new model versions ship. For Anthropic products specifically, it includes prompts for Claude Fable 5, Claude Opus 4.8, multiple Claude Code variants (with separate files for the glob tool, grep tool, deferred tools, and bundled skills), Claude Cowork, Claude Design, and integrations such as Claude for Excel, Word, PowerPoint, and iOS. Beyond Anthropic, the repository covers OpenAI's GPT-5.5 Thinking, GPT-5.5 Instant, and Codex; Google's Gemini 3.5 Flash and Antigravity CLI; xAI's Grok; and tools like VS Code Copilot Agent, Cursor, and Perplexity. Where prompts change between versions, the repository links to diff views, such as the documented change from Claude Opus 4.8 to Claude Fable 5. The primary audience is prompt engineers, AI researchers, and developers who want to understand how these systems are instructed, reverse-engineer behavioral constraints, or benchmark prompt changes across model releases. The repository received coverage in The Washington Post in May 2026.
