Screen my Marketplace buyer calls on the agent's own number

The AI runs his Facebook Marketplace sales inside rules he set

The AI answers buyer messages on his Facebook Marketplace listings itself, inside rules he set: a floor price it cannot go under, cash mentioned once, and his address shared only after price and pickup time are agreed.
