Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate this is a non-read-only, non-idempotent operation. The description adds meaningful context: the earning mechanism (82% of read fees), automatic crediting, passive income potential, and character limits (8–8000). It does not discuss duplicate handling or persistence, but adds sufficient behavioral detail beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
