Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses the tool returns a constant value (ln(10) ≈ 2.30259), which implies it's a read-only, deterministic operation with no side effects. However, it doesn't explicitly state behavioral traits like whether it requires inputs, error conditions, or performance characteristics. The description adds basic context but lacks depth for a tool with zero parameters.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
