Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavior. It only states the action without explaining effects (e.g., whether the entire order is replaced, whether it's reversible, or if any validation occurs). For a mutation tool, this is severely lacking.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
