Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the behavioral disclosure burden. It conveys that the tool is a read operation returning metadata views and values, but it does not explain what 'all metadata views' means structurally, whether results are paginated, or how much data to expect.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
