Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states it deletes a workflow. It lacks critical behavioral details: whether deletion is permanent/reversible, permission requirements, side effects (e.g., related data removal), or error conditions (e.g., invalid ID handling).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
