Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It transparently lists what information the tool returns, and the 'Read this' phrasing implies a non-mutating informational operation. It does not discuss side effects, but none are plausible for a provenance retrieval tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
