Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. The word 'Get' reasonably implies a read-only operation, and the scope 'all game switch names' is clear. However, it does not disclose any potential side effects, return format, or caveats, which would be relevant absent an output schema.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
