Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, openWorldHint=true and readOnlyHint=false, so the agent knows this is a mutating, external-facing operation. The description adds genuinely non-redundant context: it is publish-scoped, requires the publish scope, and may post automatically with auto-publish. What actually gets destroyed/altered by a wake is not detailed, keeping it below 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
