An open directory of 2,500+ AI agent skills and MCP servers that helps developers discover and install reusable skill modules for Claude Code, Cursor, Windsurf, and more IDEs.
Killer-Skills is a web-based open directory and installation entry point for developers who want reusable AI agent skills across Claude Code, Cursor, Windsurf, and 19+ other compatible IDEs.
Key capabilities include:
Skill Discovery: Search across 2,500+ open-source skills organized into categories like research, coding, marketing, and analysis.
One-Command Installation: Quick setup via the CLI using npx killer-skills add owner/repo directly from individual skill pages into supported environments.
IDE-Native Packaging: Ensures the same skill installs in the correct native format for multiple IDEs and agent environments.
Curation & Verification: Features “Official Skills” maintained by the core team and trusted partners (like Anthropic, Sentry, and Hugging Face), alongside featured community collections.
Pricing: The platform is an open-source directory; specific skill licensing depends on the individual repository, but the service itself does not specify a platform fee.
What makes it notable: It serves as a unified install flow for agent skill modules across a broad range of IDEs (19+). By centralizing install commands, supported environment data, and source repository details, it eliminates the friction of manually configuring skills for different AI-integrated development tools.
