Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden, but it only states the basic action. It does not disclose that this is a read-only operation, whether it accesses local or remote files, or any side effects. Important behavioral details like error handling or default behavior when the project parameter is omitted are missing.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
