Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description must disclose behavioral traits. It only says 'Get configuration settings' without explaining behavior like whether the key parameter is optional, what happens if the key is not found, or what the return format looks like. This is insufficient for an agent to understand the tool's full behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
