Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the full burden. It does disclose one meaningful behavioral trait — that it does not mutate READY_DATA or advance P3 maturity — which tells the agent this is a non-destructive classification. However, it says nothing about what it reads, whether it requires existing factor records, or what happens on missing data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
