Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the burden, and it does disclose a meaningful security trait: read-only, holds no key, and does not act as session key or guardian. It adds useful context for a blockchain-auth tool, though it omits any permission requirements or pagination/error behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
