Prompt engineering cheatsheet (for JavaScript developers)
Notes summarized from this tutorial.
Principle 1: Write clear and specific instructions
Tactic 1: Use delimiters to clearly indicate distinct parts of the input
Delimiters can be anything like this:
'''text'''
"""text"""
< text >
<tag>text</tag>
For instance:
const text = `
You should express what you want a model to do by \
providing instructions that are as clear and \
specific as you can possibly make them. \
This will guide the model towards the desired output, \
and reduce the chances of receiving irrelevant \
or incorrect responses. Don't confuse writing a \
clear prompt with writing a short prompt. \
In many cases, longer prompts provide more clarity \
and context for the model, which can lead to \
more detailed and relevant outputs.
`
const prompt = `
Summarize the text delimited by triple quotes into a single sentence.
"""${text}"""
`Tactic 2: Ask for a structured output
Like JSON or HTML
const prompt = `
Generate a list of three made-up book titles along \
with their authors and genres.
Provide them in JSON format with the following keys:
book_id, title, author, genre.
`Tactic 3: Ask the model to check whether conditions are satisfied
const text = `
Making a cup of tea is easy! First, you need to get some \
water boiling. While that's happening, \
grab a cup and put a tea bag in it. Once the water is \
hot enough, just pour it over the tea bag. \
Let it sit for a bit so the tea can steep. After a \
few minutes, take out the tea bag. If you \
like, you can add some sugar or milk to taste. \
And that's it! You've got yourself a delicious \
cup of tea to enjoy.
`
const prompt = `
You will be provided with text delimited by triple quotes.
If it contains a sequence of instructions, \
re-write those instructions in the following format:
Step 1 - ...
Step 2 - ...
...
Step N - ...
If the text does not contain a sequence of instructions, \
then simply write \"No steps provided.\"
"""${text}"""
`Tactic 4: "Few-shot" prompting
"Few-shot" prompting refers to providing a limited number of examples to an AI model, then having it generate new responses in a similar domain. It's a technique commonly used for training and utilizing large language models (LLMs).
The steps for few-shot prompting are:
-
Select a domain or topic you want the model to generate responses for. This could be a genre of text, way of speaking, etc.
-
Provide a small set of examples (the "prompts") from that domain for the model to condition on. Usually just 2-5 examples is sufficient for "few-shot" learning.
-
The model will analyze the patterns, styles, and structures in the prompts. It will learn the attributes that define responses in that domain.
-
Have the model generate a new response in that same domain. By conditioning on the prompts, it can produce a response that matches the desired style, structure, etc.
-
Review the response and provide feedback to further improve the model. This can either be explicit feedback to the model, or just note areas for generating the next set of prompts.
Example:
const prompt = `
Your task is to answer in a consistent style.
<child>: Teach me about patience.
<grandparent>: The river that carves the deepest \
valley flows from a modest spring; the \
grandest symphony originates from a single note; \
the most intricate tapestry begins with a solitary thread.
<child>: Teach me about resilience.
`Principle 2: Give the model time to βthinkβ
Tactic 1: Specify the steps required to complete a task
const text = `
In a charming village, siblings Jack and Jill set out on \
a quest to fetch water from a hilltop \
well. As they climbed, singing joyfully, misfortune \
struckβJack tripped on a stone and tumbled \
down the hill, with Jill following suit. \
Though slightly battered, the pair returned home to \
comforting embraces. Despite the mishap, \
their adventurous spirits remained undimmed, and they \
continued exploring with delight.
`
// example 1
const prompt_1 = `
Perform the following actions:
1 - Summarize the following text delimited by triple quotes with 1 sentence.
2 - Translate the summary into French.
3 - List each name in the French summary.
4 - Output a json object that contains the following keys: french_summary, num_names.
Separate your answers with line breaks.
Text:
"""${text}"""
`Tactic 2: Instruct the model to work out its own solution before rushing to a conclusion
const prompt = `
Your task is to determine if the student's solution \
is correct or not.
To solve the problem do the following:
- First, work out your own solution to the problem.
- Then compare your solution to the student's solution \
and evaluate if the student's solution is correct or not.
Don't decide if the student's solution is correct until
you have done the problem yourself.
Use the following format:
Question:
"""
question here
""
Student's solution:
"""
student's solution here
"""
Actual solution:
"""
steps to work out the solution and your solution here
"""
Is the student's solution the same as actual solution just calculated:
""
yes or no
"""
Student grade:
"""
correct or incorrect
"""
Question:
"""
I'm building a solar power installation and I need help \
working out the financials.
- Land costs $100 / square foot
- I can buy solar panels for $250 / square foot
- I negotiated a contract for maintenance that will cost \
me a flat $100k per year, and an additional $10 / square \
foot
What is the total cost for the first year of operations \
as a function of the number of square feet.
"""
Student's solution:
"""
Let x be the size of the installation in square feet.
Costs:
1. Land cost: 100x
2. Solar panel cost: 250x
3. Maintenance cost: 100,000 + 100x
Total cost: 100x + 250x + 100,000 + 100x = 450x + 100,000

`Iterative Prompt Develelopment
Rarely will your first prompt work as effectively as you'd like the first time (duh!).
Instead, recognize that it usually takes quite a few iterations before you can get it a place that works as well as you'd like.
Summarizing
Summarize with a word/sentence/character limit
const prod_review = `
Got this panda plush toy for my daughter's birthday, \
who loves it and takes it everywhere. It's soft and \
super cute, and its face has a friendly look. It's \
a bit small for what I paid though. I think there \
might be other options that are bigger for the \
same price. It arrived a day earlier than expected, \
so I got to play with it myself before I gave it \
to her.

In a recent survey conducted by the government,
public sector employees were asked to rate their level
of satisfaction with the department they work at.
The results revealed that NASA was the most popular
department with a satisfaction rating of 95%.
One NASA employee, John Smith, commented on the findings,
stating, "I'm not surprised that NASA came out on top.
It's a great place to work with amazing people and
incredible opportunities. I'm proud to be a part of
such an innovative organization."

Customizing the automated reply to a customer email
const review = `
So, they still had the 17 piece system on seasonal \
sale for around $49 in the month of November, about \
half off, but for some reason (call it price gouging) \
around the second week of December the prices all went \
up to about anywhere from between $70-$89 for the same \
system. And the 11 piece system went up around $10 or \
so in price also from the earlier sale price of $29. \
So it looks okay, but if you look at the base, the part \
where the blade locks into place doesnβt look as good \
as in previous editions from a few years ago, but I \
plan to be very gentle with it (example, I crush \
very hard items like beans, ice, rice, etc. in the \
blender first then pulverize them in the serving size \
I want in the blender then switch to the whipping \
blade for a finer flour, and use the cross cutting blade \
first when making smoothies, then use the flat blade \
if I need them finer/less pulpy). Special tip when making \
smoothies, finely cut and freeze the fruits and \
vegetables (if using spinach-lightly stew soften the \
spinach then freeze until ready for use-and if making \
sorbet, use a small to medium sized food processor) \
that you plan to use that way you can avoid adding so \
much ice if at all-when making your smoothie. \
After about a year, the motor was making a funny noise. \
I called customer service but the warranty expired \
already, so I had to buy another one. FYI: The overall \
quality has gone done in these types of products, so \
they are kind of counting on brand recognition and \
consumer loyalty to maintain sales. Got it in about \
two days.
