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 mentions 'owner access required' which is valuable context about authentication needs, but doesn't describe what happens after creation (e.g., whether the wallet is immediately usable, what data is returned, or if there are rate limits). For a creation tool with zero annotation coverage, this leaves significant behavioral aspects unspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
