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 high-level return content but says nothing about side effects, error behavior, what 'reproducible launch diagnostics' includes, or whether any checks are performed. The risk is low for a 0-parameter read-only tool, but the disclosure is thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
