Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Discloses a confirmation requirement, which is a behavioral trait. With no annotations, the description carries the burden of explaining side effects, but it only says 'after explicit confirmation' without detailing what happens on load (e.g., overwriting current state, auth requirements). It adds minimal context beyond the schema fields.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
