Leaked System Prompts

Leaked system prompts from widely used AI products — for prompt engineering research.

A source-verified collection of leaked system prompts — one dated markdown file per product and version, spanning Anthropic's Claude family (Claude Code, Claude Design, Opus, Sonnet), OpenAI's ChatGPT and Codex CLI, Cursor, Windsurf, Cline, Devin, Gemini, Grok, Kimi, Perplexity, and dozens more. Submissions must include verifiable sources or reproducible prompts, and the maintainer keeps the scope DMCA-conscious.

What it does

  • One dated markdown file per product and prompt version, so instruction changes are traceable over time
  • Wide vendor coverage — Claude (including Claude Code and Claude Design), ChatGPT and Codex CLI, Cursor, Windsurf, Cline, Devin, Gemini, Grok, Kimi, and dozens more
  • Verification process: pull requests need verifiable sources or reproducible prompts, checked by the maintainer before merging

When to use it

Use it to study how production products phrase guardrails, tool descriptions, and instruction hierarchies — and to compare how one product's instructions changed between versions.

Getting started

Plain markdown files — browse or clone the repository; no software to install.

Things to know

Unofficial leaked material with no license attached: accuracy cannot be verified against vendors, files go stale when products change, and the collection itself carries takedown risk.
