Why It Works
Zero-shot produced generic copy ('delightful,' 'heart of,' 'incredible value'). One-shot captured the agent's conversational voice and em-dash style. Few-shot produced the tightest writing because three examples taught AI the agent's range — short punchy lines for different property types. For listing descriptions, one-shot is the minimum. Few-shot is the gold standard.
