Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden of behavioral disclosure. The verb 'promote' implies a state-changing operation, but the description never states what actually happens to the timeline entries (are they consumed, deleted, marked?), whether changes are reversible, whether authorization is required, or what the tool returns. Consequences of the mutation are entirely undisclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
