Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds valuable behavioral context beyond the readOnlyHint annotation: it lists the specific consent documents, notes the return fields (IDs, titles, summaries, order), and emphasizes that each consent must be fetched individually. It also mentions authentication, which is relevant for a patient-session tool. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
