Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds that the operation downloads (consistent with openWorldHint) and converts into Fluent source, clarifying the transform direction. It omits where output lands, whether existing files are overwritten, and any auth requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
