Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description must carry the full burden of disclosing behavior. It states a list action, which implies a read-only operation, but does not disclose nuances like pagination, sorting, filtering, or what 'available' means. The description is too terse to provide adequate transparency for an unannotated tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
