Advanced Prompt Patterns
Explore meta-prompting, structured output formats, prompt templates with variables, multi-modal prompting, retrieval-augmented prompting, and prompt compression.
Meta-Prompting
Meta-prompting is the technique of using AI to generate prompts. Instead of writing a prompt yourself, you ask the AI to design the optimal prompt for your task. This is especially useful for complex tasks where you are not sure how to structure the prompt.
Prompt: I need to use an AI to analyze customer support tickets and categorize them by urgency, topic, and sentiment. The AI should also suggest a response template. Design the optimal prompt for this task. Include: - A clear role assignment - Specific instructions with edge cases - Output format specification - 2-3 few-shot examples - Error handling instructions The AI will generate a complete, optimized prompt that you can then use directly for your task.
Constitutional AI Prompting
Inspired by Anthropic's Constitutional AI approach, this technique involves giving the model a set of principles to follow, then asking it to self-evaluate and revise its responses against those principles.
Prompt: Generate a response to the user's question below. Then evaluate your response against these principles: Principles: 1. Accuracy: All facts must be verifiable 2. Completeness: Address all parts of the question 3. Clarity: Use simple language, avoid jargon 4. Balance: Present multiple perspectives if relevant 5. Safety: Do not include harmful or misleading info After generating your response, score it 1-5 on each principle. If any score is below 4, revise the response to improve that aspect. Show both the original and revised response. User Question: "What are the pros and cons of nuclear energy?"
Structured Output Formats
Requesting specific output formats is essential for building AI-powered applications. Here are the main formats and when to use each:
JSON Output
Prompt: Extract the following information from this job posting and return it as a JSON object: Fields: title, company, location, salary_range, required_skills (array), experience_years, remote_policy (onsite/hybrid/remote) Job Posting: """ Senior React Developer at TechCorp in Austin, TX. $130K-$160K. Hybrid (3 days office). 5+ years experience required. Must know React, TypeScript, Node.js, PostgreSQL, and AWS. """ Response: { "title": "Senior React Developer", "company": "TechCorp", "location": "Austin, TX", "salary_range": "$130K-$160K", "required_skills": ["React", "TypeScript", "Node.js", "PostgreSQL", "AWS"], "experience_years": 5, "remote_policy": "hybrid" }
XML Output
Prompt: Analyze this text and return the results in XML format with tags for: <summary>, <key_points>, <sentiment>, and <action_items>. Response: <analysis> <summary>The Q3 report shows 15% revenue growth but rising customer churn.</summary> <key_points> <point>Revenue up 15% YoY</point> <point>Churn rate increased to 8%</point> </key_points> <sentiment>mixed</sentiment> <action_items> <item>Investigate churn causes</item> <item>Launch retention campaign</item> </action_items> </analysis>
YAML and CSV
# YAML - great for configuration-like output Prompt: "Generate a deployment config in YAML format" Response: app: name: my-service version: 2.1.0 replicas: 3 resources: cpu: "500m" memory: "256Mi" # CSV - great for tabular data Prompt: "List top 5 programming languages with their use cases. Format as CSV with headers." Response: language,primary_use,popularity_rank Python,Data Science/AI,1 JavaScript,Web Development,2 TypeScript,Full-Stack Apps,3 Java,Enterprise/Android,4 Rust,Systems Programming,5
Prompt Templates and Variables
Prompt templates allow you to create reusable prompt structures with placeholders that get filled in dynamically. This is essential for production AI applications.
def create_review_prompt(product, review_text, aspects): """Generate a product review analysis prompt.""" return f""" Analyze the following {product} review. Review: "{review_text}" For each of these aspects, provide a rating (1-5) and a brief explanation: {chr(10).join(f'- {a}' for a in aspects)} Format your response as JSON with this structure: {{ "overall_sentiment": "positive/negative/neutral", "aspects": {{ "aspect_name": {{ "rating": 1-5, "explanation": "brief explanation" }} }}, "summary": "one-sentence summary" }} """ # Usage prompt = create_review_prompt( product="laptop", review_text="Great performance but battery life is disappointing. The keyboard feels premium.", aspects=["performance", "battery", "build_quality"] )
Dynamic Prompting
Dynamic prompting adjusts the prompt based on runtime conditions such as user profile, previous interactions, or external data. This enables personalized AI experiences.
def build_dynamic_prompt(user): # Adjust complexity based on user expertise if user.level == "beginner": style = "Use simple language, avoid jargon, include analogies" elif user.level == "intermediate": style = "Use technical terms with brief explanations" else: style = "Use precise technical language, assume deep domain knowledge" # Add context from previous interactions history = get_relevant_history(user.id, limit=3) return f""" {style} Previous context from this user: {history} User's current question: {user.query} """
Multi-Modal Prompting
Multi-modal prompting involves combining text with other data types like images. Models such as Claude, GPT-4V, and Gemini can process both text and images simultaneously.
# Using Claude's API with an image import anthropic client = anthropic.Anthropic() message = client.messages.create( model="claude-sonnet-4-20250514", max_tokens=1024, messages=[{ "role": "user", "content": [ { "type": "image", "source": { "type": "url", "url": "https://example.com/chart.png" } }, { "type": "text", "text": "Analyze this sales chart. Identify: (1) overall trend, (2) seasonal patterns, (3) anomalies, (4) forecast for next quarter. Format as JSON." } ] }] )
Retrieval-Augmented Prompting
Retrieval-augmented prompting combines prompt engineering with retrieved context. You fetch relevant documents and include them in your prompt to ground the model's responses in specific data.
Prompt: Answer the user's question using ONLY the provided context documents. If the answer is not in the documents, say "I don't have enough information to answer this question." Context Documents: --- Document 1 (Company Policy - Updated Jan 2026): [retrieved content here] --- Document 2 (Employee Handbook Section 4.2): [retrieved content here] --- User Question: "What is the company's policy on remote work for new employees?" Instructions: - Cite the specific document and section - Quote relevant passages - If documents conflict, note the discrepancy - Do not use knowledge outside these documents
Prompt Compression Techniques
When dealing with large contexts or limited token budgets, prompt compression helps you convey maximum information in minimum tokens:
Abbreviation
Use standard abbreviations and remove filler words. "Please provide a detailed analysis of" becomes "Analyze:"
Structured Shorthand
Use lists, bullets, and key-value pairs instead of prose. Saves 40-60% of tokens with the same information.
Summarized Context
Summarize long documents before including them. Use a first pass to extract key points, then include only those.
Schema References
Define a schema once, then reference it. "Follow the JSON schema above" instead of repeating the full schema.
