Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description adds a content inventory (OAuth metadata, installer client identifiers, project-handoff status, workflow stages), but since an output schema exists this largely restates return values rather than disclosing new behavior such as auth prerequisites or caching semantics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
