Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description is the sole source of behavioral information. The description is straightforward but minimal; it does not mention any side effects, permissions, or limitations beyond the basic 'lists courses you are enrolled in.' For a simple read-only tool, this is adequate but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
