 A **Multi-Agent Orchestration & Messaging Backplane** built on [herdr](https://herdr.dev) and MQTT. It runs long-lived coding agents (`claude`, `agy`, `hermes`, `grok`, `opencode`, `codex`) in isolated herdr panes, delegates work to them as tracked jobs, and drives planner / creator / reviewer loops until every reviewer passes the change.
