Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the tool executes queries and returns results, but doesn't specify whether this is read-only or can modify data, what permissions are required, whether there are rate limits, what format the results come in, or any error conditions. For a general query execution tool with no annotation coverage, this leaves significant behavioral questions unanswered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
