Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden for disclosing side effects, permissions, or error conditions. It only states the data returned and implies a read-only operation via the word 'Engagement', but does not explicitly confirm safety, ownership restrictions, or failure behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
