Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must fully disclose behavioral implications. 'Disable registrar lock' conveys the core action but omits critical details such as whether the lock must currently be enabled, any verification steps, reversibility, or potential impacts on domain transfers. This is insufficient for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
