This repository is a curated, multi-vendor collection of leaked system prompts from major AI chatbots (ChatGPT, Claude, Gemini, Grok, Perplexity, DeepSeek, etc.), captured verbatim from production systems. It serves as a reference corpus for studying AI behavior instructions, safety guardrails, tool definitions, and product positioning across model versions and vendors. The repository also includes Claude Code bundled skills (code review, design-sync, dataviz, deep research) and Claude Design starter components, which are supplementary tooling. While primarily a documentation archive, it contains some well-crafted reusable components such as color palette validation scripts, a design system build/diff pipeline, and a deep research workflow script. The prompts are organized by vendor with version tracking, and the repository is actively maintained with recent updates. However, the tooling scripts lack dependency pinning, and the prompts are time-sensitive snapshots that will drift as products evolve.
