Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full burden of behavioral disclosure. It indicates a state-changing operation ('complete') but gives no details on prerequisites beyond timing, potential side effects, error conditions, or what the function returns. For an OAuth completion step, an agent might need to know whether it can be called multiple times, what happens if called before authorization, or how to handle failures. This is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
