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 communicate the destructive overwrite semantics ('replace all current protocols'), which is the key behavioral trait. But it doesn't disclose side effects on protocol progress or tracking state, especially relevant given the sibling tick_protocol.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
