Prompt

Zero-shot prompting is the foundation — no examples, just clear instruction. Techniques: 1. Task Definition — state exactly what you want in the first sentence. "Classify the following review as positive, negative, or neutral." 2. Format Specification — define the output shape. "Respond with only the label, no explanation." 3. Constraint Framing — set boundaries. "Use only information provided. Do not infer." 4. Role Priming — "You are an expert [your domain] analyst" activates relevant knowledge without examples. 5. Instruction Ordering — put the most important constraint first. Models attend most to the beginning. 6. Negative Constraints — "Do NOT include..." is often more effective than "Only include..." Zero-shot works best when the task is well-defined and the model has strong prior knowledge. When accuracy drops, add examples (few-shot) or reasoning (CoT). The art is knowing which technique to reach for.
