Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states 'Query the database' but doesn't disclose critical behavioral traits: whether it's read-only or can modify data, authentication requirements, error handling, result format, or performance implications. For a database tool with zero annotation coverage, this leaves significant gaps in understanding how the tool behaves.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
