Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses what the tool returns (skills_count, total_downloads, etc.) which is somewhat behavioral, but it does not explicitly state that this is a read-only operation, nor does it mention permissions, rate limits, or side effects. For a simple getter, this is adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
