Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of disclosing behavioral traits. It states the action cannot be undone, which is a key warning for a deletion operation. However, it omits other important behaviors such as whether associated tasks are cascaded or if deletion is blocked when tasks exist, leaving gaps in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
