Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must fully disclose behavioral traits. It states the tool fetches data and returns full definition, but fails to mention that it's read-only, what happens on invalid ID, rate limits, or authentication requirements. For a simple fetch, this is a notable gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
