β¨οΈ Precision Instructions. Reliable Output.
Prompt Engineering
The gap between a useful AI and a useless one is the prompt. Learn the six techniques that separate operators who get reliable, structured, zero-hallucination output from those who don't.
The Core Principle
A large language model is a stochastic function. The same input produces different outputs each time. Prompt engineering is the discipline of writing instructions so precise that the variance collapses β the model behaves like a deterministic system, producing the same quality of output every time.
6 Core Prompting Techniques
Each technique targets a specific failure mode. Use them in combination for production-grade reliability.
Role + Context + Task (RCT) Framework
The single most impactful prompt structure. Define who the model is, what it knows, and exactly what you need. Eliminates 70% of hallucination by setting a constrained scope.
System: You are a senior financial analyst specializing in SaaS unit economics. Context: The company has $2M ARR, 500 customers, 5% monthly churn. Task: Calculate LTV:CAC ratio and identify the top 2 levers to improve it. Format: Bullet points, max 150 words.
Chain-of-Thought (CoT) Prompting
Force the model to show its reasoning step by step before reaching a conclusion. Dramatically improves accuracy on multi-step problems, math, and complex analysis tasks.
Task: Determine if this refund request is valid. Think through the following steps before answering: 1. What did the customer purchase? 2. What is the stated reason for the refund? 3. Does the reason meet our policy criteria? 4. What is your final decision and rationale? Then output: Decision + one-sentence explanation.
Few-Shot Examples
Provide 2β3 examples of ideal input/output pairs before your actual request. Locks the model into your desired format, tone, and depth without lengthy instructions.
Example 1: Input: "We need more leads" Output: "Define lead quality criteria, build ICP, deploy outbound + content in parallel." Example 2: Input: "Revenue is flat" Output: "Audit churn first. Then test price increase on renewals. Then open a new channel." Now respond to: "Our sales cycle is too long"
Output Format Constraints
Always specify format explicitly. JSON, markdown table, numbered list, max word count, required sections. Unstructured output is unusable in automated workflows.
Respond ONLY in valid JSON with this exact schema:
{
"decision": "approve" | "reject" | "escalate",
"confidence": 0.0-1.0,
"reason": "string (max 50 words)",
"next_action": "string"
}
Do not include any text outside the JSON object.Negative Constraints
Tell the model what NOT to do. Prevents common drift behaviors: padding responses, making up data, changing the format, or going off-topic.
Rules: - Do NOT fabricate statistics. If you don't know, say "Unknown." - Do NOT include disclaimers or caveats unless directly relevant. - Do NOT exceed 200 words. - Do NOT suggest consulting a professional β I am the professional. - Do NOT restate the question in your answer.
System Prompt Architecture
Separate your static instructions (persona, rules, format) from dynamic inputs (the actual request). Enables you to reuse the same system prompt across thousands of calls with consistent output.
[SYSTEM β never changes]
You are an expert B2B copywriter. Always write in second person. Sound like a veteran operator, not a consultant. Max 120 words per output.
[USER β changes every call]

The right model for the right task. Prompt quality matters more than model choice β but model choice matters for cost and context.
| Model | Best For | Avoid When | Cost |
|---|---|---|---|
| GPT-4o | Reasoning, code, structured output | Very long documents | $$ |
| Claude 3.5 Sonnet | Long context, writing, nuance | Real-time data | $$ |
| Gemini 1.5 Pro | 1M token context, multimodal | Complex multi-step logic | $ |
| Llama 3 (local) | Privacy, no API costs | State-of-the-art reasoning | Free |
