Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description carries the full burden. It does disclose an important behavioral trait: the tool runs in the user's Kuudo deployment, not in the current environment. But it does not mention read-only semantics, authentication needs, output format, or whether 'Catalog entry' means it is only a placeholder.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
