Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully communicate behavioral aspects. It only says 'tracker', implying read-only, but lacks details on output format, pagination, rate limits, or any side effects. This is insufficient for an agent to understand behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
