Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description includes the [mutation] tag, indicating a state change, and specifies the campaign should be 'completada'. However, it does not disclose what happens after archiving (e.g., whether it hides the campaign, if it's reversible, or error conditions for non-completed campaigns). With no annotations, the description carries the full burden but provides only minimal behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
