About KILLER-SKILLS
KILLER-SKILLS is a web-based open directory designed for developers who need reusable AI agent skills across multiple IDEs. It centralizes discovery and installation of 2,500+ open-source skills, including modules for research, coding, marketing, and analysis. The platform provides one-command installation via CLI using npx killer-skills add owner/repo, streamlining setup directly from individual skill pages into supported environments like Claude Code, Cursor, Windsurf, and 19+ other compatible IDEs. Skills are packaged in IDE-native formats to ensure correct installation across different agent environments. The directory features curated collections, including ‘Official Skills’ maintained by core teams and trusted partners such as Anthropic, Sentry, and Hugging Face, alongside community-contributed skill sets. While the platform itself is open-source and free to use, licensing for individual skills depends on their respective repositories.
