Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Since no annotations are provided, the description carries full responsibility. It states the read-only nature via the verb '列出' (list) and specifies the return fields (name, version, description), giving agents a concrete expectation of the output. It does not mention edge cases like empty lists or pagination, but the simple scope is adequately disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
