Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, so the description carries the burden, and it does disclose a security-relevant behavioral trait: names and hints only, never secret values. It does not cover auth/permission requirements, pagination, or scoping side effects beyond the parameter's own text.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
