Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states this is a 'get' operation, implying read-only behavior, but doesn't confirm if it's safe, whether it requires specific permissions, or if it has rate limits. It mentions 'detailed information' but doesn't specify what that includes (e.g., user attributes, roles) or potential errors (e.g., invalid ID). For a tool with zero annotation coverage, this leaves significant behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
