Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden of disclosing behavior. It reveals that the operation is a state change ('mark as ready'), but does not say whether this actually publishes components, whether it is reversible, what permissions are required, or what happens to components already marked ready.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
