Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are absent, so the description must carry the behavioral disclosure burden. It only states the action and parameters, but does not mention read-only nature, response format, side effects, or any constraints (e.g., rate limits). This is insufficient for an agent to understand 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.
