Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Run a query to database' implies a potentially mutating operation (e.g., INSERT, UPDATE, DELETE) but doesn't specify if it's read-only, destructive, requires authentication, has rate limits, or what the output format is. This is a significant gap for a tool with no annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
