Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden. 'Adopt' implies a write/mutation operation that likely changes device state, but it doesn't disclose behavioral traits such as required permissions, whether it's idempotent, potential side effects, or error conditions. This leaves significant gaps for an agent to understand the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
