Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden for behavioral disclosure, but it only says 'get target tracks.' It does not explain what target tracks are, whether the operation is purely read-only, what the return value looks like, or any side effects. The 'get' verb weakly implies no mutation, but little else is disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
