Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only states 'poll task status/result' without revealing idempotency, side effects, prerequisites (e.g., task must exist), or what happens if the task is still running. This is insufficient for an agent to understand the tool's behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
