Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses the max 40 character constraint for the name, which is not in the schema. However, it lacks details on permissions, idempotency, or what happens if the tag already exists. With no annotations, the description carries more burden but only partially fulfills it.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
