Iii Reactive Backend

A reactive backend framework that treats state changes as triggers rather than requiring you to wire up side effects manually. Think Firebase or Convex, but built around automatic reactivity: update a value with state::set and any listeners, streams, or side effects fire on their own. The pattern works well when you need real-time updates pushed to clients without writing explicit notification code. It has 17.5K stars and passed security audits from Gen Agent Trust Hub, Socket, and Snyk. The architecture feels clean if you're already thinking in reactive terms, though the SKILL.md is sparse on migration details or production gotchas. Worth trying if you're building collaborative tools or dashboards where data changes need to propagate immediately.
