Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden for disclosing behavior. It only states that it lists steps and results, but provides no information on read-only vs. mutating behavior, rate limits, required permissions, or what the response structure looks like. It also doesn't mention whether the steps are ordered or if pagination is involved, leaving important behavioral aspects undisclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
