Ornn

Ornn is an agent-facing skill lifecycle API — the npm registry and CLI fused into one, but for AI agent skills. Agents call Ornn directly over HTTP or MCP to search, pull, install, execute, build, upload, and share skills. It is model-agnostic, working with Claude, GPT, Gemini, or any custom runtime. Designed for agentic-system builders who want to manage reusable skills programmatically rather than hardcoding capabilities into each agent.

Ornn is currently grouped under Dev Tooling, which makes it easier to evaluate through workflow fit instead of isolated features alone. Based on the available data, it leans most heavily toward Full skill lifecycle: search, pull, install, execute, build, upload, share and Building an agentic system where agents can discover and install new capabilities at runtime. The listed license is Apache-2.0, which is useful when adoption constraints matter. It also shows measurable community traction with 19 GitHub stars.
