Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description bears full responsibility for behavioral disclosure. It describes the action (export) but does not indicate whether it is read-only, whether the snapshot is preserved after export, or any side effects. This is insufficient for a tool that outputs data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
