Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose all behavioral traits. It does state that the operation is a write and requires confirmation, which is some disclosure. However, it doesn't explain what confirmation entails, what parameters are needed for confirmation (e.g., confirm_token, confirmation_id), or what the side effects of the write are. The description is too sparse to give an agent confidence in how the tool behaves.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
