Really enjoyed this perspective. The idea that uncertainty should be treated as an explicit part of the system rather than simply another error to patch really stood out to me. It’s tempting to keep adding guardrails whenever an agent behaves unexpectedly, but that can eventually make the system overly rigid. I especially liked the comparison with exception handling in distributed systems it makes the concept much easier to understand. Defining where deterministic control ends and where the agent is allowed to reason and adapt seems like an important architectural decision. Looking forward to seeing how the next parts explore reliability and maintainability in practice.
