Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It states the core behavior (clearing overrides and resetting to defaults), which is transparent about the main effect. However, it does not disclose any side effects, reversibility, or what happens if no overrides are active, leaving some gaps for a tool that performs a global reset.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
