Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description should disclose behavioral traits. It only states it queries details, but does not mention that it is read-only, whether it requires authentication, rate limits, or what happens if the pool doesn't exist. This lack of transparency could lead to incorrect usage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
