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 states the tool returns metadata but doesn't disclose important behavioral traits: whether it's read-only (implied but not stated), pagination or rate limits, authentication requirements, error conditions, or what happens with large graphs. For a listing tool with zero annotation coverage, this leaves significant gaps in understanding its operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
