Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With empty annotations, the description carries the full burden of disclosing behavior, but it does not state that the tool is read-only, what it returns, or any side effects. The name suggests a lookup, but the description never explicitly says it reads or retrieves settings, nor does it mention response structure or limitations. This is a significant gap for a tool with no annotation support.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
