Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, openWorldHint=false, and idempotentHint=true. The description adds a quality claim about being 'verified against the official Discover Canada guide' but does not disclose any behavioral aspects beyond what annotations provide. The bar is lowered due to annotations, and the description adds some value but not substantial 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.
