Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral disclosure burden. The verb 'Check' implies a read-only diagnostic actionchers, which is a meaningful behavioral signal. However, it does not state what happens on success/failure, whether any system state can be changed, or what output the agent should expect, leaving important behavior implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
