Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations available, the description carries the disclosure burden and covers meaningful behavioral ground: it requires an auth token and performs source URL validation before publishing. It does not detail side effects such as visibility or irreversibility, but the disclosed auth and sequencing exceed a bare action statement.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
