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 the action ('Load') but doesn't explain what 'load' entails—whether it's a read-only operation, if it modifies data, requires authentication, or has rate limits. This leaves critical behavioral traits unspecified for safe invocation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
