Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for behavioral disclosure, but it only says 'analyze' without addressing side effects, read-only nature, or what inputs are accessed. The sparse description does not clarify whether the tool modifies anything or what data it relies on.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
