Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It implies a read-only operation but does not mention pagination, return format, or the folder scoping that contradicts the phrase 'all solution articles'. The requirement for folder_id is a key behavior that is omitted, making the tool appear more global than it actually is.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
