Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It does disclose one useful trait – results are scoped to the signed-in employee, not a passed-in user – but says nothing about permissions, whether settings are read-only, or what a caller should expect.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
