Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It does mention the authorization requirement ('x-agent-key and task ownership') and the existence constraint, which is useful. However, it does not disclose side effects (e.g., append vs overwrite) or the response shape, leaving some behavioral ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
