Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of disclosing behavior. It only says it gets status and tails logs, without mentioning what happens for invalid session IDs, whether it returns immediately or waits, or what the status response contains. It does not disclose any side effects or permission requirements, leaving the agent to infer the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
