Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish the tool as read-only, idempotent, and non-destructive, lowering the burden on the description. The description adds useful behavioral context: this opens a fuller page than a preview and is tied to Pod search result IDs. No contradiction with annotations is present.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
