Turning the Leaked Claude Prompt Into a Universal Version
Velocity_Off · reddit · 2026-07-19
The author claims to have distilled the leaked Claude Fable 5 system prompt into a **universal 500-token Markdown agent prompt**, compatible with ChatGPT and Gemini. The original prompt is reportedly around 120,000 characters long, incurring massive inference overhead, with much of it tied to Anthropic's internal infrastructure. By stripping away this "enterprise noise," the author preserved core principles like self-verification, strict formatting constraints, and high autonomous execution. The full prompt is shared in the post, alongside a GitHub repository for forking and starring.
