Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full disclosure burden. It does state the output shape ('each short definition as well as the name') and the non-mutating verb 'List' implies a read-only operation. It doesn't cover ordering guarantees, behavior for categories with no terms, or how the listed items connect to goji_explain_term, but for a simple browse tool the disclosed behavior is adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
