Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the behavioral disclosure burden. It clearly explains the data source (BacklinkMCP's proprietary web-scale link index), the scoring emphasis, and the return values (domain_rating-style score plus referring domain count). It does not mention rate limits, freshness, or explicit read-only status, but the 'Get' verb and described output provide meaningful behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
