Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare idempotentHint=true and openWorldHint=true, which cover retry safety and open-world behavior. The description adds minimal extra context by specifying 'all restrictions', but does not disclose potential side effects or permission requirements. It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
