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 only says 'retrieves the current permalink structure' — implying a read operation but providing no details on permissions, return format, caching, or side effects. This is minimal and does not add meaningful behavioral context beyond the title.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
