Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. 'Create' implies a write operation, but it doesn't specify permissions needed, whether this is idempotent, what happens on failure, or what the response looks like. It lacks details on rate limits, authentication requirements, or side effects, which are critical for a creation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
