Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only states a simple action ('show') with no details about the output format (e.g., list vs. single result), determinism, limitations, or what 'standard' means. This is a minimal disclosure that leaves many behavioral aspects unexplored.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
