Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly=false, openWorld=true, idempotent=true, destructive=false, so the safety profile is covered. The description adds genuinely useful context beyond that: the operation is a two-step flow that returns a link, nothing is connected until the user approves, and no password/key is passed — meaningful behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
