Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. It discloses that the tool creates a real order and returns a payment link, indicating a mutation. However, it does not specify potential side effects (e.g., whether the draft is invalidated after use), error handling, or idempotency. Given the absence of annotations, more behavioral detail would be beneficial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
