Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without annotations, the description explains the verification mechanism (checking _agentstamp.domain.com TXT record and cross-referencing the registry) and notes the tool is free. However, it does not disclose return behavior, error handling, or permission requirements, leaving some behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
