Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosure. It does disclose the destructive nature ('Delete') and the requirement for confirmation, which are important behavioral traits. However, it omits details about what gets destroyed (e.g., associated docs), authentication prerequisites, or whether the action is reversible.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
