Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden of disclosing behavior. 'List' implies a read-only operation, which is a basic behavioral trait. However, it does not disclose any details about pagination, sorting, permissions, or return format. Given the simplicity of the tool, this is adequate but lacks depth, meriting a mid-range score.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
