What it does

This repository aggregates system prompts, internal tool definitions, and AI models from commercial coding agents and assistants—Cursor, Devin, Replit, Windsurf, Claude Code, and others listed in the description. The README itself is essentially a sponsorship and donation page; the actual content lives in the repository tree, which the maintainer admits took effort to “obtain and share.” If you want to read the hidden instruction manuals behind these tools, this is the unofficial archive.

The interesting bit

The maintainer simultaneously publishes these leaks and runs ZeroLeaks, a service that helps AI startups prevent prompt extraction—a tidy bit of vertical integration. With 141,494 stars, the project has become a de facto transparency library for developers obsessed with how their favorite IDEs are wired to think.

Key highlights

Covers 25+ products including Cursor, Devin AI, Replit, Windsurf, VSCode Agent, and Perplexity
141,494 stars reveal intense curiosity about proprietary system instructions
README includes a “Security Notice” warning startups that exposed prompts are hacker targets
Monetized via sponsorships, crypto donations, and the ZeroLeaks security-audit service

Caveats

The README previews no actual prompts and reveals almost nothing about file structure or sourcing
The listed “Latest Update” is 10/05/2026, a future date that suggests placeholder or stale metadata

Verdict

Worth bookmarking for prompt engineers, red-teamers, and anyone who enjoys reading other people’s instruction manuals. Skip it if you need officially licensed documentation or a carefully curated, well-sourced dataset.
