Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description reveals key behaviors: no image upload, caller-supplied dimensions, optional distortion check, payment ref consumed by gateway, and idempotency key. With no annotations, this provides adequate behavioral context, though it does not mention error handling or side effects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
