Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of disclosing behavior. The word 'soft' hints that the operation is non-destructive, but it does not explain side effects (e.g., whether the item disappears from listing, whether it can be restored, what happens to related entities). For a mutation tool, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
