Introduction
Prompt engineering is the skill of writing instructions so AI models produce accurate, useful output on the first try. It is not magic — it is structured communication.
Why This Topic Matters
A strong prompt can turn a 30-minute task into a 3-minute task. Weak prompts waste tokens, produce hallucinations, and frustrate teams.
Real-Life Example
Instead of "write python code", use: "Act as a senior Python developer. Write a binary search function with type hints, docstring, and 3 pytest test cases. Explain time complexity."
Syntax Breakdown
Use the CRISPE framework:
Capacity & Role — who the AI should act as
Request — the exact task
Instruction — steps and constraints
Situation — background context
Persona — tone and audience
Experiment — ask for variations if needed
Step-by-Step Code Explanation
Example prompt template:
``
Role: Technical writing assistant for IT Vizag students
Task: Explain Python list comprehensions
Constraints: Max 200 words, include 1 code example, beginner-friendly
Format: Markdown with headings
`Few-shot pattern:`
Convert notes to bullet summaries.
Input: "Python uses indentation for blocks"
Output: "
Python relies on indentation (not braces) for code blocks"
Input: "Lists are ordered and mutable"
Output: "
Lists store ordered items and can be changed after creation"
Now convert: "Functions reduce repeated code"
``
Expected Output
Clear, structured AI responses that match your format, audience, and constraints — without endless re-prompting.
Common Beginner Mistakes
Being vague ("make it better")
Asking for too many unrelated tasks in one prompt
Forgetting to specify output format
Not providing examples for complex tasks
Best Practices
Start with role + task + format
Use few-shot examples for repetitive formats
Set temperature low (0–0.3) for factual tasks
Iterate: refine one section of the prompt at a time
Practice Problems
#
Easy — Problem 1
Write a CRISPE prompt asking AI to summarize a news article in 5 bullet points for a 10th-grade reader.
#
Medium — Problem 2
Create a few-shot prompt that converts informal WhatsApp messages into professional email replies.
#
Hard — Problem 3
Design a prompt chain: first extract facts, then verify, then format as a table.
Mini Assignment
Pick a real task from your studies or job. Write 3 prompt versions (bad, okay, excellent). Compare AI outputs and note differences.
Lesson Summary
Clear prompts with role, context, constraints, and format produce the best AI results. Treat prompting as a repeatable skill, not guesswork.
