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 uses 'Check' and 'Shows,' implying a read-only operation with no side effects. However, it does not explicitly state read-only status, mention authentication requirements, or clarify whether 'remaining rate cap allowances' refers to the tool's own rate limits or the agent's reward caps. This leaves some ambiguity, though the overall intent is clear.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
