Notes on Agents

Practical notes on building production agent systems — from a single control loop to policy-as-code, multi-agent coordination, eval, and durable execution. The running example is ShopOps: Northline support for a stalled order, with draft≠send as a hard rule.

Jordan asks where order O-1001 is. Maya opens a ShopOps case. The system loads facts, proposes a path, checks policy, drafts outreach — and only sends after approval.
