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 'fetch' suggesting a read operation, but does not confirm safety, disclose if the operation has side effects, or mention prerequisites like permissions. The phrase 'full HAL detail' lacks elaboration on response format or pagination.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
