Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description usefully adds that the returned artifact is a controller targeting the /api/v1/payment endpoint, but discloses nothing about what the snippet contains or requires. With annotations doing the heavy lifting, this is an adequate but modest contribution.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
