Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral insight. It implies a state-changing operation ('Pause') but doesn't disclose whether this requires specific permissions, if it's reversible (though 'props_resume_auto_clear' suggests it is), what 'auto-clear' entails, or any side effects. More context is needed for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
