Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description fully carries the behavior disclosure burden. It does reveal one useful fact—'No identifiers are retained'—but it omits whether the operation is read-only, what 'classification' means, or any side effects. For an unannotated tool with four parameters, this is insufficient behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
