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 states that it 'finds' broken references, but does not specify whether it is read-only, what it returns (e.g., a list, summary, errors), or whether it modifies anything. This is a significant gap for a validation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
