Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for behavioral disclosure. It states that the tool returns captured traffic, but does not disclose whether the operation is read-only, whether it flushes or clears the buffer, or any other side effects. 'Dump' suggests retrieval, but the lack of explicit safety information is a gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
