Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavioral traits. The verb 'Retrieve' clearly implies a read-only, side-effect-free operation, and it lists the specific state aspects returned. However, it does not explicitly state failure modes (e.g., what happens if no bulb is connected) or any additional behavioral nuances.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
