Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It reveals that the output is portable and can be restored in another environment, including a self-hosted installation, which is meaningful context. However, it does not state whether the operation is read-only, what side effects exist, or any permission or state-capture details.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
