Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description only says 'through Frenchie', implying an external service, but does not disclose behavioral traits such as potential side effects, network usage, or whether files are modified. Annotations indicate readOnlyHint false, but the description adds no further context beyond the raw conversion action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
