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 clearly states this is a destructive operation ('This action cannot be undone'), which is crucial context for a deletion tool. However, it doesn't mention authentication requirements, rate limits, error conditions, or what happens to associated data, leaving some behavioral aspects unspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
