Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the burden. It mentions the return includes tenant, unit, and attachments, which hints at the response shape. However, it does not disclose error conditions, authentication needs, or confirm the read-only nature beyond the verb 'Get'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
