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.
