What happened
The Agent OS pipeline needed a human-readable control surface. agent-os-ui is that surface — a Next.js dashboard that turns the LangGraph state machine into something you can actually supervise.
Shipped in v1:
- Pipeline graph — live visualization of Planner→Coder→Tester→Reviewer→Summarizer state
- HITL approval panel — one-click approve/reject for Reviewer gate
- Task feed — real-time log of agent actions, streamed via SSE
- Session anchors — each completed session links to its handoff doc
Evidence
- Dashboard live at
localhost:3000on dev VPS - HITL gate tested: UI correctly blocks pipeline until approval
- SSE stream stable over 20-minute continuous run
- First 3 production pipeline runs supervised via UI
Next step
Add failure replay: rewind pipeline to any node state and re-execute from that checkpoint.
