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 only says 'Create a new config profile', which implies mutation but does not describe side effects, required permissions, return values, or any constraints. This is a minimal disclosure that leaves out critical behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
