Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden, yet it discloses almost nothing: no behavior on an out-of-range index, no indication of what happens to the dialog afterward, and no error semantics. The single disclosed trait is the 1-based indexing convention.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
