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 action ('claim rewards') but does not describe what 'claim' entails—e.g., whether it's a read-only operation, if it modifies state, requires authentication, has side effects like token transfers, or involves rate limits. 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.
