Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description explicitly declares the tool as 'Read-only', which is a key behavioral trait. In the absence of annotations, this disclosure is valuable and sufficient for a simple tool with no side effects. However, no further details on output format or performance implications are provided.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
