Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description bears full responsibility. It discloses return content (skill name, description, downloads, rating, trust level) and the popularity-sorted behavior for agent-optimized search, along with limit constraints (default 20, max 50). However, it doesn't discuss auth or error conditions, which are less critical for a read-only search.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
