Built by Austrian vibe coder Peter Steinberger, OpenClaw is MIT-licensed, local-first (Markdown files on disk), and community-extensible through a SKILL.md format. The community stories are wild — one agent negotiated USD 4,200 off a car purchase over email while the owner slept. Skills are shared through ClawHub, a searchable registry. The architecture is surprisingly similar to what we are building with the Mind system: messaging-first, skill-based, local storage. Worth studying.
