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 explicitly states that the action cannot be undone, which is a critical behavioral trait. It does not mention related side effects (e.g., on meal plans), but for a simple delete by slug, this is sufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
