Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure, but it only says 'convert' and fails to mention critical consequences such as the container becoming a template, becoming non-startable as a regular container, or the irreversible nature of the operation. No side effects, permissions, or state changes are disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
