Field notesAgents as Code
01 / Position
Systems thinking for agents in production.
I work where AI agents meet the less glamorous constraints that make them dependable: identity, policy, observability, networking, and operator control.
Built from field work.
Documented without theatre.
02 / Current systems
Working systems, shown with constraints.
Three parts of one operating model: define the agent, observe what it does, and govern what it may reach.
