Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only repeats the tool name. It does not disclose read-only nature (though implied by 'Get'), nor does it mention behavior when no sequence is active or when in/out points are not set. No return format or error conditions are described.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
