Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. 'Cancel an order' implies a destructive mutation, but it doesn't disclose behavioral traits like whether cancellation is reversible, what permissions are needed, how it affects related entities (e.g., inventory, payments), or error conditions. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
