Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the burden of behavioral disclosure. It does explicitly say 'Irreversible action', which is a meaningful warning about side effects. However, it does not disclose whether execution is synchronous, whether it can be repeated safely, what happens to target data, or how results/status are returned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
