Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool 'obtém informações detalhadas' (gets detailed information), implying a read-only operation, but doesn't specify aspects like authentication requirements, rate limits, error handling, or the format of returned data. For a tool with zero annotation coverage, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
