Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It discloses nothing: whether files are modified in the directory, whether api_key is used as a signing secret, what 'token-based' means concretely, or whether the operation is idempotent. An agent cannot anticipate any side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
