Agent design / note 01
Deterministic agents need explicit state, not better vibes
Production agent failures usually come from weak boundaries: hidden state, vague retries, and handoffs nobody can inspect.
Systems design
State management
When a workflow is unreliable, better prompting is rarely the first answer. Most failures trace back to orchestration design that was left implicit.
A reliable agent system makes state visible, constrains transitions, and logs why it moved from one step to the next. That discipline is what turns a demo into infrastructure.
