Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It states 'delete' implying a destructive operation, but doesn't specify permissions required, whether deletion is permanent/reversible, or any side effects (e.g., impact on associated deals). This leaves significant gaps for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
