The original and largest open-source prompt library — 143,000+ GitHub stars, featured by Forbes, cited by Harvard and Columbia, and the most-liked dataset on Hugging Face. Started in December 2022 as a curated collection of role-based prompts, it has grown into a full prompt management platform with MCP server and Claude Code plugin.
