Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must disclose behavioral traits. It states the tool 'List available forms' and describes the return, implying a read-only operation. However, it lacks details on permissions, side effects, or whether forms are site-wide, resulting in adequate but minimal transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
