Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must convey behavioral traits. It does not disclose if this operation is destructive, if it overwrites the existing file, or if it requires specific permissions. The description only states what it rebuilds but not the consequences or safety profile.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
