Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses one behavioral limitation (cannot detect Colab runtime) but omits other important traits like whether the operation is read-only, requires authorization, or has side effects. The name implies read-only, but the description should be explicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
