Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations provide readOnlyHint=false, idempotentHint=true, and destructiveHint=false, indicating it's a non-destructive, repeatable mutation. The description adds minimal context by specifying the action involves moving between projects/lists, but doesn't elaborate on behavioral traits like permissions needed, effects on task metadata, or error conditions. No contradiction with annotations exists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
