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 that deletion cascades to sources, chunks, and vectors, which is critical for an agent to understand the destructive scope. However, it does not mention irreversibility, permissions, or other side effects, keeping it below a perfect score.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
