Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden. It only says 'Get a specific organization_unit by ID,' which restates the tool's name and offers no details about error behavior (e.g., 404 if not found), response format, or authorization requirements. It adds minimal behavioral context beyond the obvious read intent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
