Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of disclosing behavior. It accurately describes a read-only list operation and mentions the output fields (IDs and names). However, it does not mention any limitation, auth requirements, or data format details, which are minimal for a simple list but still a slight gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
