Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It makes clear the tool exposes field metadata rather than performing a mutation, and it notes that allowed options are included only where they exist. It does not explicitly say the operation is read-only, describe response wrapping, or mention any constraints, so it is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
