Prompt Engineering Deep Dive: Mastering the CO-STAR Framework
In this article, we do a deeper dive in Prompt engineering—the art of crafting instructions for large language models (LLMs) like ChatGPT ( GPT3, GPT4 ) or Gemini ( Gemini Pro, Gemini Ultra ) or Claude etc. If you skimmed the basics in my last article, it’s time to elevate your skills with the CO-STAR framework. CO-STAR framework is one of the most popular and trusted templates for better results with Prompts. I have been using this framework for my own interactions with LLMs getting much better responses. This structured approach helps you create tailored prompts, leading to far superior and insightful AI outputs.
CO-STAR: Your Prompt Powerhouse
So why use CO-STAR? Here’s where it shines:
Focus: LLMs thrive on clear goals. CO-STAR helps you set specific objectives for your prompts.
Specificity: Providing rich context allows the LLM to generate outputs that are laser-focused on your needs.
Customization: With CO-STAR, you tailor the tone, style, and target audience of your prompts, unlocking the LLM’s full potential.
CO-STAR in Action: A Creative Scenario
Imagine you run a small business specializing in handcrafted home decor. To stand out, you need fresh marketing copy for social media. Let’s see CO-STAR work its magic!

"ChatGPT Plus" Response: using GPT4 LLM gave the below result:
Absolutely! Crafting engaging and creative captions can really highlight your home decor business on social media. Here are some ideas across different themes:
Inspirational

Seasonal
“Fall in love with your space all over again this autumn 🍂 Embrace cozy vibes with our latest collection. #AutumnInteriors #CozyHome”
“Spring has sprung, and so have our latest decor trends! Refresh your space with vibrant colors and fresh designs. 🌸 #SpringDecor #HomeRefresh”
Motivational

Humorous

“Sofa so good! Discover couches that you’ll never want to leave. Warning: May cause extreme coziness. 🛋️😉 #HomeHumor #CozyLiving”
Call to Action

“Don’t just dream about a beautiful home, make it a reality. Visit our website or DM us to start your home decor journey today! 🌈 #DecorDreams #StartToday”
These captions can be adjusted to fit the specific aesthetic and branding of your business, as well as the social media platform you’re using. Remember, the key is to engage your audience with a mix of product highlights, inspirational content, and calls to action.
While the LLM gave varied options, they lack specificity, clarity, branding and targeting . Let’s try CO-STAR for the same scenario.
Context: “My business uses reclaimed wood and vintage textiles to create one-of-a-kind home decor. I want to emphasize sustainability and a cozy, nostalgic feel.”
Objective: “Write three Instagram captions that highlight these aspects.”
Style: “Short, impactful, and friendly.”
Tone: “Warm and inviting.”
Audience: “Eco-conscious people who love a home with character.”
Improved Response:
Absolutely, emphasizing the unique and sustainable aspects of your business in a warm and inviting tone can really connect with your target audience. Here are three Instagram captions tailored to your needs:
“Every piece tells a story 🌿 Crafted from reclaimed wood and vintage textiles, our decor not only adds warmth to your home but also to the planet. #SustainableLiving #CozyHomeVibes”
“Bring a piece of history into your living space. Our one-of-a-kind decor, made from reclaimed materials, offers both charm and a step towards a greener earth. 🌎💚 #EcoChic #NostalgicHome”
“Embrace the beauty of the past with a touch that feels right at home. Our sustainable, vintage-inspired pieces are perfect for adding that cozy, nostalgic feel. Together, let’s make sustainability stylish. 🏡❤️ #VintageCharm #SustainableStyle”
These captions are designed to resonate with eco-conscious individuals who appreciate homes with character, emphasizing the sustainability and unique cozy appeal of your products.
The Difference is Clear
Context (C): Setting the scene for your request.
Output or Objective (O): Spelling out what you want to get back.
Specificity or Style (S): Being super clear so there’s no mix-up.
Task or Tone (T): The job you’re asking AI to do.
Assumptions or Audience (A): Any guesswork you’re expecting AI to make. Or Audience you are catering to.
Requirements or Response (R): The must-haves for your answer.
Here’s a breakdown of those CO-STAR template variations, providing nuance and clarifying how they influence your prompts:
Provides: The backstory, subject matter, relevant keywords, and any crucial details the AI needs to understand the “world” your prompt exists in.
Example: “I’m an interior designer looking for modern color palettes that combine blue and yellow in a playful way.”
2. Output or Objective (O): Spelling out what you want to get back
Guides: The specific format and result you desire. Could be a piece of text, code, a list, a table, etc.
Example: “Generate five color palette names and their corresponding hex codes.”
3. Specificity or Style (S): Being super clear so there’s no mix-up
Specificity: Gives more detail about the nature of your required output to avoid ambiguity and generic responses.
Style: Dictates the register and “feel” of the language the AI should use (formal, playful, technical, etc.)
Example: “Specificity: Focus on bright, joyful tones. Style: Whimsical and evocative.”
4. Task or Tone (T): The job you’re asking the AI to do
Task: Expresses the action you want the AI to perform - analyze, summarize, translate, write, etc.
Tone: Sets the mood, feeling, or attitude in the final response.
Example: “Task: Write a persuasive sales pitch. Tone: Bold and confident.”
5. Assumptions or Audience (A): Any guesswork you’re expecting AI to make, or the audience you’re catering to
Assumptions: Helps the AI ‘fill in the blanks’ on things you may not explicitly state (e.g., target audience knowledge, or assumptions about the goal of the content)
Audience: Guides the AI in selecting vocabulary, references, and style appropriate to your intended readers or consumers.
Example: “Assumption: Customer doesn’t understand jargon. Audience: Teenagers looking for a trendy new backpack.”
6. Requirements or Response (R): The must-haves for your answer
Requirements: Outlines non-negotiable elements, length limits, and other constraints the response must adhere to.
Example: “Requirement: Maximum 200 words. Include at least one SEO keyword from the following list: [list of keywords].”
