Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It explicitly states 'This action cannot be undone,' which is a key trait. However, it does not mention potential cascading effects on associated projects, tasks, or time records, nor authentication requirements. The irreversibility warning adds value but leaves room for more context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
