1. What is Prompt Engineering?
Prompt engineering is the practice of designing and optimizing inputs (prompts) to AI systems like ChatGPT, Claude, or Gemini to get the best possible outputs. It's the bridge between human intent and AI capability.
A prompt can be as simple as a question or as complex as a multi-page system specification. The difference between a good prompt and a great prompt can mean the difference between useless output and transformative results.
The Anatomy of a Prompt
Role/Persona
Who is the AI? "You are an expert Python developer with 10 years of experience..."
Context
Background information the AI needs. User data, constraints, requirements, examples.
Task/Instruction
What do you want the AI to do? Be specific and clear about the desired action.
Format/Output Structure
How should the response be structured? JSON, markdown, code, bullet points, etc.
Constraints
What should the AI avoid? Length limits, topics to exclude, style guidelines.
Examples (Few-Shot)
Show the AI what you want with input-output examples before asking for the actual task.
Simple vs Engineered Prompt
| Simple Prompt | Engineered Prompt |
|---|---|
| "Write a cover letter" | "You are a career coach helping a recent CS graduate apply for a software engineering role at Google. Write a cover letter that: 1) Opens with a hook, 2) Highlights 2 specific projects, 3) Shows cultural fit, 4) Is under 300 words. Use confident but not arrogant tone." |
2. Why Prompt Engineering Matters
The Impact of Good Prompting
- Quality: Well-crafted prompts can improve output quality by 50-300%
- Consistency: Structured prompts produce more reliable, repeatable results
- Efficiency: Reduce iterations and back-and-forth with better initial outputs
- Cost: Fewer tokens = lower API costs for production applications
- Safety: Well-designed prompts reduce harmful or off-topic responses
Who Needs Prompt Engineering?
Everyone (Basic Level)
Every knowledge worker will use AI tools. Basic prompt skills will be as essential as email or spreadsheets.
Professionals (Intermediate)
Marketers, writers, designers, analysts, developers—domain experts who integrate AI into their work.
Specialists (Advanced)
Dedicated prompt engineers who design AI systems, optimize prompts for production, and solve complex problems.
3. Core Prompting Techniques
1. Zero-Shot Prompting
Asking the AI to perform a task without any examples. Relies on the model's pre-trained knowledge.
Example:
"Classify the sentiment of this review as positive, negative, or neutral: 'The food was amazing but the service was slow'"
2. Few-Shot Prompting (Critical Technique)
Providing examples of input-output pairs before the actual task. Dramatically improves accuracy and consistency.
Example:
"Classify sentiment:
Review: 'Loved it!' → Positive
Review: 'Terrible experience' → Negative
Review: 'It was okay' → Neutral
Review: 'The food was amazing but service was slow' → ?"
3. Chain-of-Thought (CoT) Prompting (Most Important)
Asking the AI to show its reasoning step by step. Dramatically improves performance on complex tasks.
Example:
"Solve this problem step by step: If a train travels at 60 mph and needs to cover 150 miles, but stops for 30 minutes midway, how long is the total journey?"
Trigger phrases:
"Let's think step by step" / "Show your reasoning" / "Explain your thought process"
4. Role Prompting
Assigning a specific persona or role to the AI to shape its responses.
Examples:
- • "You are a senior software engineer at Google..."
- • "Act as a Socratic tutor who asks guiding questions..."
- • "You are a legal expert specializing in contract law..."
5. Output Formatting
Explicitly specifying the structure and format of the response.
Techniques:
- • Request JSON for structured data
- • Use markdown headers for organization
- • Specify tables for comparative information
- • Define schemas for consistent outputs
6. Constraint Setting
Defining boundaries and limitations for the response.
Examples:
- • "Keep response under 200 words"
- • "Only use information from the provided context"
- • "Do not use technical jargon"
- • "Avoid speculation; state facts only"
4. Advanced Prompting Strategies
Self-Consistency
Generate multiple responses and take the majority answer. Useful for reasoning tasks.
Tree of Thoughts (ToT)
Have the AI explore multiple reasoning paths, evaluate them, and choose the best one. For complex problem-solving.
ReAct (Reasoning + Acting)
Combine reasoning with tool use. The AI thinks, acts (uses tools), observes results, and continues.
Recursive Prompting
Break complex tasks into subtasks. Use output from one prompt as input to the next.
Meta-Prompting
Ask the AI to help you write better prompts for a task.
Example:
"I want to use AI to summarize research papers. What would be the ideal prompt structure? Consider tone, format, and key information to extract."
Prompt Chaining
Link multiple prompts in sequence, where each builds on the previous output.
1. Generate outline →
2. Expand each section →
3. Add examples →
4. Review and refine
