Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavioral traits. It does not mention potential side effects (e.g., executing all due events, possible performance impact), whether the operation blocks until completion, or what the return value indicates. The single sentence provides no context beyond the action itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
