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. 'Accept all tracked changes' implies a mutation, but it does not disclose whether changes are irreversible, whether the document must be saved afterward, or what impact it has on comments or other artifacts. This is a significant gap for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
