Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It only states that details are retrieved, without disclosing what 'details' include, whether a missing gym_id yields an error, or any access requirements. For a read tool, this is minimal information.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
