Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the burden of behavioral disclosure. It does disclose that no API key is required and that the tool is read-oriented ('fetch', 're-check'), but it does not explain error behavior, rate limits, or what happens for an invalid id. It gives some useful context but is 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.
