Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It states the tool returns identity and firmware info, which implies a read operation, but it does not disclose behavior such as whether the 'extended' parameter changes the output shape, whether it requires a connection to the mixer, or whether it has side effects. The description is minimal and leaves behavioral traits undisclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
