Self-improving agent from Nous Research — writes its own skills from experience and carries them forward.
The learning loop is the point: it creates skills after complex tasks and searches its own past sessions. Runs anywhere from a $5 VPS to Modal or Vercel Sandbox.
Open-source meta-harness that orchestrates Claude Code, Codex, Cursor, OpenCode, Hermes and Pi from one session, on any device.
A common orchestration layer over other harnesses rather than a harness of its own — swap Claude Code/Codex/Cursor/etc. in and out, enforce policies, and run sessions in cloud sandboxes (Modal, Daytona, E2B and others).
