Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It does disclose the key behavioral detail that the tool returns the template's HTML content, which is useful. However, it does not mention potential errors, authorization requirements, or any other side effects. For a simple read-only GET, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
