Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations supplied, the description must carry the full burden of explaining behavior. It does not disclose whether this operation is read-only, whether it requires a project to be open, what side effects occur, or what the output looks like. The name implies a read operation but this is never verified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
