Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With annotations present the bar is lower, and the description still adds real context: authorization requirements, retry semantics, and the explicit non-effect on bounty outcome. The retry-is-safe wording sits slightly at odds with idempotentHint=false, but this reads as scoping one field rather than a flat contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
