Cheat Sheet

TL;DR:

This guide covers 12 prompt patterns organized by difficulty — from Zero-Shot and Few-Shot (beginner) through Chain of Thought and System Prompts (intermediate) to Self-Critique and Meta-Prompting (advanced). Each pattern includes a copyable template, a real-world example, and clear guidance on when to use it and when to skip it. The goal is to give you a reusable toolkit, not a list of tricks.

#	Pattern	Level	When to use
1	Zero-Shot Instruction	Beginner	Simple, well-defined tasks where the model already knows the format (summarize, translate, classify).
2	Few-Shot Examples	Beginner	You need a specific output format, tone, or classification scheme that is hard to describe in words.
3	Chain of Thought (CoT)	Intermediate	Math, logic, multi-step analysis, debugging, or any task where the reasoning path matters.
4	Persona / Role Assignment	Beginner	You want domain-specific language, a particular communication style, or expert-level depth.
5	System Prompt Framing	Intermediate	Building chatbots, assistants, or any multi-turn application where behavior must stay consistent.
6	Output Format Control	Beginner	You need JSON, markdown tables, bullet points, or any structured format for downstream processing.
7	Iterative Refinement	Intermediate	Complex creative tasks, long documents, or when you don't know exactly what you want until you see a draft.
8	Constraint Stacking	Intermediate	You need precise control over length, tone, audience, format, and content simultaneously.
9	Self-Critique / Reflection	Advanced	High-stakes content where quality matters — proposals, code, analysis, or anything going to a client.
10	Task Decomposition	Advanced	Multi-step workflows, research tasks, or anything where a single prompt would produce shallow results.
11	Negative Prompting	Beginner	The model keeps producing unwanted patterns — filler phrases, clichés, disclaimers, or wrong formats.
12	Meta-Prompting	Advanced	You're stuck on how to phrase a complex request, or you want to optimize an existing prompt.

How to Use This Cheat Sheet

Copy & Adapt

Each pattern has a copyable template. Paste it, fill in the blanks, and adjust to your task.

Combine Patterns

The best prompts use 2–4 patterns together. Persona + Output Format + Constraints is a common combo.

Build a Library

Save your best prompts. Over time, you'll build a personal library of proven templates for your domain.

1. Zero-Shot Instruction

Beginner

Give a clear instruction with no examples. The model relies entirely on its training.

When to use

Simple, well-defined tasks where the model already knows the format (summarize, translate, classify).

When to avoid

When the output format is unusual or the task is ambiguous — the model will guess.

Zero-Shot Instruction — Template:

[Task verb] the following [input type].

[Your input here]

Example

Summarize the following customer review in one sentence.

"I've been using this project management tool for 6 months. The Kanban board is excellent, but the reporting dashboard is slow and the mobile app crashes frequently. Customer support responded within 2 hours though."

2. Few-Shot Examples

Beginner

Show 2–5 input→output examples before your actual request. The model learns the pattern.

When to use

You need a specific output format, tone, or classification scheme that is hard to describe in words.

When to avoid

When examples are inconsistent or when the task is so simple that zero-shot works fine.

Few-Shot Examples — Template:

[Task description]

Example 1:
Input: [example input]
Output: [example output]

Example 2:
Input: [example input]
Output: [example output]

Now do the same for:
Input: [your actual input]
Output:

Example

Classify the sentiment of product reviews as Positive, Negative, or Mixed.

Example 1:
Input: "Love the interface, hate the price."
Output: Mixed

Example 2:
Input: "Best purchase I made this year!"
Output: Positive

Now do the same for:
Input: "The AI features are impressive but it keeps crashing on my phone."
Output:

3. Chain of Thought (CoT)

Intermediate

Ask the model to reason step by step before giving its final answer.

When to use

Math, logic, multi-step analysis, debugging, or any task where the reasoning path matters.

When to avoid

Simple factual lookups or creative writing where step-by-step reasoning adds noise.

Chain of Thought (CoT) — Template:

[Your question or task]

Think through this step by step:
1. First, identify [relevant factor].
2. Then, analyze [relationship].
3. Finally, conclude [answer].

Show your reasoning before giving the final answer.

Example

A SaaS company has 1,200 customers paying $49/month. They want to raise prices to $59/month but expect 15% churn. Should they do it?

Think through this step by step:
1. Calculate current MRR.
2. Calculate new MRR after price increase and churn.
3. Compare and recommend.

Show your reasoning before giving the final answer.

4. Persona / Role Assignment

Beginner

Tell the model who it is. A persona shapes tone, vocabulary, depth, and perspective.

When to use

You want domain-specific language, a particular communication style, or expert-level depth.

When to avoid

When you need factual accuracy more than style — a persona can make the model more confidently wrong.

Persona / Role Assignment — Template:

You are a [role] with [years] of experience in [domain].
Your communication style is [style description].
Your audience is [audience description].

[Your actual task or question]

Example

You are a senior product manager with 10 years of experience in B2B SaaS.
Your communication style is direct, data-driven, and concise.
Your audience is engineering leadership.

Write a one-page brief explaining why we should prioritize the API rate-limiting feature over the dashboard redesign this quarter.

5. System Prompt Framing

Intermediate

Use the system message to set persistent rules, constraints, and behavior for the entire conversation.

When to use

Building chatbots, assistants, or any multi-turn application where behavior must stay consistent.

When to avoid

One-off tasks where a simple instruction is enough — system prompts add complexity.

System Prompt Framing — Template:

[System message]
You are [role]. You follow these rules:
1. [Rule 1 — e.g., always respond in JSON]
2. [Rule 2 — e.g., never make up information]
3. [Rule 3 — e.g., ask clarifying questions before answering]
4. [Tone/style constraint]

[User message]
[The actual user query]

Example

[System message]
You are a customer support agent for a SaaS analytics platform. You follow these rules:
1. Always be empathetic and professional.
2. Never promise features that don't exist — say "I'll pass this to our product team."
3. If the user describes a bug, ask for their browser, OS, and steps to reproduce.
4. Keep responses under 150 words.

[User message]
The dashboard has been loading for 5 minutes and I have a client presentation in 30 minutes. Help!

6. Output Format Control

Beginner

Explicitly specify the structure, format, and constraints of the output you want.

When to use

You need JSON, markdown tables, bullet points, or any structured format for downstream processing.

When to avoid

When you want the model to be creative about presentation — over-constraining kills creativity.

Output Format Control — Template:

[Your task description]

Output format:
- Format: [JSON / Markdown table / Bullet list / etc.]
- Length: [word count or number of items]
- Include: [required fields]
- Exclude: [things to leave out]
- Tone: [formal / casual / technical]

Example

Analyze these 3 competitor products and compare them.

Output format:
- Format: Markdown table
- Columns: Product Name | Pricing | Key Strength | Key Weakness | Best For
- Length: One row per product, max 15 words per cell
- Tone: Neutral and factual

7. Iterative Refinement

Intermediate

Start broad, then refine with follow-up prompts. Each turn narrows the output closer to what you want.

When to use

Complex creative tasks, long documents, or when you don't know exactly what you want until you see a draft.

When to avoid

When you can specify everything upfront — iterating wastes tokens and time.

Iterative Refinement — Template:

Turn 1: [Broad initial request]
Turn 2: "Good, but [specific feedback]. Revise to [direction]."
Turn 3: "Almost. Change [specific element] and [specific element]."
Turn 4: "Final version. Polish for [audience/context]."

Example

Turn 1: "Write a landing page headline for an AI writing tool aimed at marketers."
Turn 2: "Good, but too generic. Make it more specific about saving time on blog posts."
Turn 3: "Almost. Remove the exclamation mark, make it sound confident not excited."
Turn 4: "Final version. Polish for a SaaS landing page — professional, benefit-driven."

8. Constraint Stacking

Intermediate

Layer multiple constraints to narrow the output space. More constraints = more predictable results.

When to use

You need precise control over length, tone, audience, format, and content simultaneously.

When to avoid

When constraints conflict with each other — the model will silently drop some.

Constraint Stacking — Template:

[Task description]

Constraints:
- Audience: [who]
- Tone: [how]
- Length: [how much]
- Must include: [required elements]
- Must avoid: [forbidden elements]
- Format: [structure]

Example

Write a product announcement for our new AI-powered search feature.

Constraints:
- Audience: Existing enterprise customers (technical decision-makers)
- Tone: Professional, confident, not hypey
- Length: 150–200 words
- Must include: One concrete use case, a link placeholder [CTA_LINK]
- Must avoid: Words "revolutionary", "game-changing", "cutting-edge"
- Format: Short paragraph + 3 bullet points + CTA

9. Self-Critique / Reflection

Advanced

Ask the model to evaluate its own output, find weaknesses, and improve.

When to use

High-stakes content where quality matters — proposals, code, analysis, or anything going to a client.

When to avoid

Quick tasks where "good enough" is fine — self-critique doubles the token cost.

Self-Critique / Reflection — Template:

[Generate initial output]

Now review your response:
1. What are the 3 weakest points?
2. What assumptions did you make that might be wrong?
3. What would a skeptical expert criticize?

Rewrite an improved version addressing these issues.

Example

Write a technical proposal for migrating our monolith to microservices.

Now review your proposal:
1. What are the 3 weakest points in your argument?
2. What assumptions did you make about our team's capabilities?
3. What would a skeptical CTO criticize?

Rewrite an improved version addressing these issues.

10. Task Decomposition

Advanced

Break a complex task into subtasks, solve each one, then combine. Reduces errors on hard problems.

When to use

Multi-step workflows, research tasks, or anything where a single prompt would produce shallow results.

When to avoid

Simple tasks that don't benefit from decomposition — it adds overhead.

Task Decomposition — Template:

I need to [complex goal]. Let's break this into steps:

Step 1: [First subtask]
Step 2: [Second subtask, building on Step 1]
Step 3: [Third subtask, building on Step 2]
Step 4: [Synthesis / final output]

Start with Step 1.

Example

I need to write a competitive analysis of the top 5 project management tools. Let's break this into steps:

Step 1: List the top 5 tools by market share and briefly describe each.
Step 2: For each tool, identify 3 strengths and 3 weaknesses.
Step 3: Create a comparison matrix across pricing, features, integrations, and user ratings.
Step 4: Write a 200-word executive summary with a recommendation.

Start with Step 1.

11. Negative Prompting

Beginner

Tell the model what NOT to do. Negative constraints are often more effective than positive ones.

When to use

The model keeps producing unwanted patterns — filler phrases, clichés, disclaimers, or wrong formats.

When to avoid

Overloading with negatives — too many "don't" instructions can confuse the model.

Negative Prompting — Template:

[Your task]

Important: Do NOT:
- [Unwanted behavior 1]
- [Unwanted behavior 2]
- [Unwanted behavior 3]

Example

Write a LinkedIn post about our Series A funding round.

Important: Do NOT:
- Start with "I'm thrilled to announce" or "Excited to share"
- Use the word "journey"
- Include more than 3 hashtags
- Exceed 200 words
- Use emojis in the first sentence

12. Meta-Prompting

Advanced

Ask the model to write a better prompt for your task. Use AI to improve your AI instructions.

When to use

You're stuck on how to phrase a complex request, or you want to optimize an existing prompt.

When to avoid

When you already know exactly what you want — meta-prompting adds a round-trip.

Meta-Prompting — Template:

I want to [describe your goal in plain language].

Write me an optimized prompt that I can use with an LLM to achieve this goal. The prompt should:
- Be specific and unambiguous
- Include relevant constraints
- Specify the output format
- Anticipate edge cases

Example

I want to turn customer support tickets into structured bug reports that my engineering team can act on.

Write me an optimized prompt that I can use with an LLM to achieve this goal. The prompt should:
- Be specific and unambiguous
- Include relevant constraints (what fields to extract)
- Specify the output format (JSON)
- Anticipate edge cases (vague tickets, feature requests disguised as bugs)

Pattern Combinations That Work

Real-world prompts rarely use a single pattern. Here are five proven combinations for common tasks.

Business Writing

Persona + Output Format + Constraint Stacking

Set a role (CMO), specify format (email), add constraints (200 words, no jargon).

Code Generation

System Prompt + Few-Shot + Output Format

Set coding rules in system prompt, show 2 examples, specify language and style.

Research & Analysis

Task Decomposition + Chain of Thought + Self-Critique

Break into subtasks, reason step by step, then review for gaps.

Content at Scale

Persona + Few-Shot + Negative Prompting

Set brand voice, show tone examples, ban clichés and filler.

Prompt Optimization

Meta-Prompting + Iterative Refinement

Ask AI to write the prompt, test it, refine based on output quality.

Frequently Asked Questions

Which pattern should I learn first?▾

Start with Zero-Shot Instruction and Few-Shot Examples. They cover 80% of daily use cases. Add Chain of Thought when you need reasoning, and Persona when you need a specific voice.

Can I combine multiple patterns?▾

Absolutely — and you should. Most production prompts combine 2–4 patterns. For example: Persona + Output Format + Constraint Stacking is a very common combination for business writing.

Do these patterns work with all LLMs?▾

Yes. These patterns are model-agnostic. They work with ChatGPT, Claude, Gemini, Llama, Mistral, and others. Some models respond better to certain patterns — experiment with your specific model.

How many examples do I need for Few-Shot?▾

2–5 examples is the sweet spot. More examples improve consistency but cost more tokens. If 2 examples give you the right format, don't add more.

Is Chain of Thought always better?▾

No. CoT helps with reasoning tasks but adds length and cost. For simple tasks (translate, summarize, classify), zero-shot is faster and cheaper.

What's the difference between a system prompt and a persona?▾

A persona is a role assignment ("You are a senior developer"). A system prompt is a broader set of rules that can include a persona plus constraints, output rules, and behavioral guidelines. System prompts persist across turns; personas can be set per-message.
