Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the full burden of behavioral disclosure. It does disclose the core side effect: 'marking it as submitted with timestamp.' However, it omits other relevant behavioral traits such as reversibility, permission requirements, or the outcome of submitting an already-submitted inject. It provides basic transparency but lacks depth for a mutation operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
