This is one of the more practical explanations of agentic systems I've read lately.
The line "an assistant answers you; an agent does the thing" sounds simple, but the real insight is that the gap isn't model intelligence—it's execution, permissions, guardrails, and observability.
I especially liked the principle: "Let the model be wrong cheaply, but never wrong expensively." That's the difference between a demo and a production system. Read/write separation, human approval for state-changing actions, and keeping permissions enforced by deterministic code are patterns that scale far better than simply trusting the model.
We've seen similar lessons emerge at IT Path Solutions when building AI agents for business workflows. The challenge is rarely getting the model to call a tool; it's designing the surrounding system so mistakes are contained, recoverable, and auditable.
Great breakdown of why agent engineering is fundamentally a systems design problem.
