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 mentions the permission requirement ('Requires write_mode'), which is valuable context. However, it doesn't describe what 'delete' entails (e.g., permanent vs reversible, cascading effects on related resources like executions), nor does it address rate limits, error conditions, or response format. For a destructive operation with zero annotation coverage, this leaves significant gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
