Ornn vs openInvest

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.; openInvest: openInvest is a self-hosted investment decision engine that plugs into agents such as Claude Code, Codex, Hermes and OpenClaw. It runs an information-isolated multi-agent committee, keeps an auditable decision trail and publishes backtests and negative results, positioning itself as a discipline and transparency tool rather than an alpha generator.
