Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of revealing side effects. 'Clean build artifacts' implies deletion or removal, but it does not state what exactly is deleted, whether it is safe to run, or if it has any irreversible consequences. This is a significant gap for a potentially destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
