Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, establishing it as a safe read operation. The description adds value by specifying the return fields (status, gas used, logs) but does not disclose additional behavioral traits such as potential rate limits or dependency on transaction existence.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
