Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden for behavioral disclosure. It indicates a read-style 'get' operation but does not explain what paths are included, whether the result is scoped to the current project, size/performance implications, or the return shape. No behavioral traits beyond the operation name are disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
