One skill format, deployed to 46 AI coding agents
Write a skill once and translate it into the formats used by all 46 supported agents, including hooks, MCP tools and context conventions.
Search and browse hundreds of thousands of skills across 35+ aggregated registries and sources, organized into a hierarchical skill tree.
Generate skills from plain language using Claude, GPT-4, Gemini, Ollama or OpenRouter, and auto-generate optimized agent instructions from your codebase.
A 46-rule scanner flags prompt injection, secrets and malicious patterns, while a built-in test framework with assertions validates skills before deployment.
