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. It effectively explains that deletion moves items to a recycle bin rather than permanent removal, which is crucial behavioral context not evident from the name alone. However, it doesn't mention permission requirements, rate limits, or error conditions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
