Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states that the tool fetches details, which is an implicit read operation, but does not mention return format, permissions, side effects, or any constraints beyond the uuid. For a simple getter this is minimal but not fully transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
