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, but 'Share... to the community database' only states the action and destination. It does not disclose whether the share is reversible, whether it makes the template publicly visible, what happens if the template is already shared, or any permission requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
