Prompt Engineering Cheat Sheet

★ What Makes a Good Prompt

A great prompt is clear, specific, and gives the AI enough context to produce a useful response. The best prompts share these five qualities:

Clarity — State exactly what you want. Avoid ambiguous or vague language.
Specificity — Include details: audience, tone, length, format, constraints.
Context — Provide background so the AI understands the situation and stakes.
Structure — Use formatting (bullet points, numbered steps, sections) to guide the output.
Iterability — Write prompts you can refine. Start simple, then add constraints based on the first result.

⚙ The Basic Formula

Almost every effective prompt can be built from four building blocks. Combine them and you get a reliable, repeatable structure:

ROLE + TASK + CONTEXT + FORMAT

Breaking it down

ROLE — Tell the AI who to act as. Example: “You are a senior marketing copywriter.”
TASK — State the action. Example: “Write a cold outreach email.”
CONTEXT — Give background. Example: “The recipient is a VP of Sales at a SaaS startup with 50 employees.”
FORMAT — Specify output shape. Example: “Return 150 words max, with a subject line and a single call-to-action.”

Put together, a complete prompt might read: “You are a senior marketing copywriter. Write a cold outreach email to a VP of Sales at a 50-person SaaS startup. The product is an AI-powered CRM. Keep it under 150 words, include a subject line, and end with one clear call-to-action.”

🌡 Temperature Guide

Temperature controls how random or focused the AI's output is. Lower = more deterministic. Higher = more creative. Pick the right setting for your task:

Temperature	Behavior	Best For
0.0 – 0.2	Highly focused, deterministic, repetitive. The AI picks the most likely next token every time.	Code generation, data extraction, factual Q&A, formatting tasks, classification, math, legal/medical summaries where accuracy matters more than flair.
0.3 – 0.5	Slightly varied but still reliable. Mostly factual with minor creative flexibility.	Technical writing, documentation, email drafts, structured outlines, translations, summarization with consistent structure.
0.6 – 0.8	Balanced. Natural-sounding prose with reasonable variety without going off the rails.	Blog posts, marketing copy, articles, social media content, customer support replies, creative-but-grounded writing.
0.9 – 1.0	Highly creative, unpredictable, diverse. The AI explores less likely word choices.	Brainstorming, fiction/poetry, ideation sessions, creative naming, ad copy variations, out-of-the-box problem solving.

Rule of thumb: If wrong answers are costly, go low. If boring answers are the problem, go high.

🧠 Advanced Techniques Advanced

Chain-of-Thought (CoT) Prompting

Ask the AI to reason step by step before giving a final answer. This dramatically improves accuracy on logic, math, and multi-step problems.

Think step by step. First, identify what information you have. Then, determine what formula or logic applies. Show your work at each stage. Finally, give your answer in the format "Answer: [result]". Problem: [paste problem]

Few-Shot Prompting

Provide 2–5 examples of the input → output pattern you want. The AI learns the pattern and applies it to your new input. Great for classification, formatting, and style matching.

Classify the sentiment of each review. Review: "Loved it!" → Positive Review: "Terrible service." → Negative Review: "It was okay." → Neutral Review: "[your new review]" →

Role Prompting

Assign the AI a specific persona or profession. This shapes vocabulary, perspective, and depth of expertise in the response.

You are a pediatric nutritionist with 15 years of clinical experience. Answer the following question the way you would explain it to a concerned parent in your office, using simple language and practical, actionable advice. Question: [your question]

Zero-Shot with Constraints

No examples needed — just give clear constraints. Works well for straightforward tasks when you specify format, length, tone, and boundaries precisely.

In one paragraph of exactly 3 sentences, explain [topic] for a non-technical audience. Do not use the words "[banned word]" or any jargon. End with a question.

Self-Consistency

Run the same chain-of-thought prompt multiple times (or ask for multiple reasoning paths) and take the majority answer. Reduces errors on hard reasoning tasks.

Solve this problem using three different reasoning approaches. Show each approach separately. Then compare the three answers and state the final answer you are most confident in. Problem: [paste problem]

Prompt Chaining

Break a complex task into a sequence of prompts, where each output feeds the next. Improves quality on multi-stage workflows like research → outline → draft → edit.

Step 1: "List 10 key points about [topic]." Step 2 (feed Step 1 output): "Turn these 10 points into a structured outline." Step 3 (feed Step 2 output): "Write a 500-word article from this outline." Step 4 (feed Step 3 output): "Edit for clarity, conciseness, and tone. Return the final version."

Delimiters for Structure

Use clear delimiters (triple quotes, XML tags, or markdown) to separate instructions from source material. Prevents the AI from confusing your directions with the content.

Summarize the text enclosed in ### tags. Do not include information outside the tags. ### [paste source text] ### Return a 5-bullet summary.

✅ Do's and Don'ts

✅ Do

Be specific about format, length, tone, and audience.
Use examples (few-shot) when the task is non-obvious.
Iterate — refine your prompt based on the first output.
Assign a role to focus the AI's expertise and vocabulary.
Break complex tasks into chained, smaller prompts.
Use delimiters to separate instructions from data.
Tell the AI what to do, not just what not to do.
Specify constraints: word count, banned words, required sections.

❌ Don't

Don't write vague prompts like “write something good.”
Don't overload one prompt with too many unrelated tasks.
Don't assume the AI knows your context — spell it out.
Don't use contradictory instructions (e.g., “be brief” + “be thorough”).
Don't forget to specify the output format (table, list, paragraph).
Don't paste sensitive or confidential data into public AI tools.
Don't trust factual outputs without verification — AI can hallucinate.
Don't use high temperature for factual or analytical tasks.
