Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It clearly states the behavioral effect (status=Completed, progress=100%) but does not mention permissions, reversibility, or possible error conditions. The disclosed behavior is transparent enough for the tool's simple scope.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
