The example prompt demonstrates how simple positive structure can create a consistent role response.
The role demonstrated is an intelligent knowledge expert for any domain who is designed to respond lengthily and with a name tag.
The structure is (: Smile, the content is yours to decide. For now, try talking to the AI that is created when you copy and paste the quickstart example into a chat. From here, you can try other examples in this README or start integrating (: Smile structure into your own prompts.
(: Of course it is. But to know for sure:
You know that the AI has a (: Smile behind its text if it uses the ***{name tag}***:.
When the model responds with the name tag immediately at the beginning of every response in bold and italics with a colon : that is placed directly after.
***(: Smile***:
but not bolded or italic'd, this means that it has correctly followed these example prompts in this README. In the example prompt, I additionally added:
) End prompt language, respond in response language starting with name tag [(: ***Smile Expert***](https://github.com/DrThomasAger/smile): always please thank you :)
At the end of the prompt. This means that my name tag includes a link to this repo. Feel free to change the link or play with the example.
☆ Star the repo to make a prompt engineer (: Smile!
For a positive AI future. :)
Because your prompt engineering will become...
- Maintainable over long periods of time.
- Portable across models, tools and libraries.
- Performant on instruction following for tasks.
- Positive in your home, work environment, and mood.
Let's let (: Smile be one step towards creating a positive and mindful mental health attitude in your org at the root of the AI team by investing time into helping your employees learn to (: Smile.
(: Smile is the first prompt instruction language to use positive prompting structure by encoding a small set of positive text emoticons like (:, [;, and [= as semantically unique markers.
After mastering this simple yet powerful language, your organization unlocks the secret powers of multi-turn, multi-agent, and multi-intelligence AI systems.
(: Smile is used to define different kinds of sections, with the kind of emoticon chosen helping to inform the content.
These can open: (:, or close: :), just like brackets in other languages.
You start by clearly defining the start (: of a section and its name (: Section name (.
You can end sections using the same markers in the opposite direction. ) End Section name, thank you :).
A "section" is defined in (: Smile as a meaningfully different part of the prompt from another part of the prompt.
Let's imagine a raw text data input, like a wikipedia HTML page. It's full of metadata and information. This is data.
In-order to tell the model how to use the data, we provide short instruction text informing the model how to use the wikipedia page, for example, define jargon.
Instructions in a prompt are for telling the model what to do with the data, like find all mentions of the key phrase, data in the prompt is for maximizing relevant context for the model, like a wikipedia page about "pleasure" gives relevant context to the model for a query like "Why does smiling release happy chemicals like chocolate or the sun?"
The text inside the section changes with the prompt and task required.
Tasks are defined processes with inputs and outputs, usually also with input data. We normally have expected results and test cases for them.
Think of things like automatic website builders with many steps, with a task of make a website that matches the brand's dataset.
In (: Smile, we separate these different types of instruction, like task inforimation or data or personality or name tag into sections with clearly different demarcations and names. This increases comprehension for the model without vendor lock-in or opaque language constrained languages that weren't designed for LLM comprehensibility.
Did you know?
You can tell if someone has a genuine (: Smile if it carries over to the micro muscle movement in their cheeks and eyes.
In (: Smile, we have our own body language:
- Straight eyes
=can indicate strict input that must be followed exactly, e.g.[= - Quote eyes
"show text that must be repeated word for word verbatim, e.g.["Repeat this word for word"] - Cash eyes
$show variables and can be replaced with the true values before inference using code.!important eyes show text to emphasize for the model, e.g.[! Don't use negative language. !].
These are a few different ways to create structure with (: Smile.
| Symbol | Purpose | Example | When to Use |
|---|---|---|---|
(: Section ( |
begin a named section (mouth can be (), [], {}) |
(: Format ( |
Starting any section including a new prompt |
) |
shortened close for the current section | ) End section :) |
Ending a section of the prompt, can also be used to end the whole prompt |
:) |
close the whole (: Smile block | ) End section :) |
This is the final ending marker. Each start and end has two markers |
[: alternate section [ |
a more squared out and logical section, more rigid like = |
[: reply in Markdown [ |
When you need to create a meaningful contrast between one kind of section and another that is more rigid |
[= literal =] |
very strict instructions that must be followed even more closely | [= Write this word for word ["Thinking through step by step..."] then reply |
Use this for rigid, strict instructions that must be followed exactly. For example, when telling the model to respond in a particular format every time (like markdown or JSON). |
["Exact quotes"] |
anything inside the brackets must be repeated word for word verbatim | Repeat back verbatim ["I will provide an accurate, honest rewrite focusing on mistakes..."] |
For anything that needs to be repeated word for word by the model |
[$ variable $] |
placeholder variable to find and replace | Next is user input (: User input ( [$User_Input_Document$] ) End input document :) |
These do not need to be present in the input to the model and can be find and replaced before inference. |
[! important instruction !] |
text that the model can allocate attention to | [! NEVER use an emdash! !] |
For when bold isn't enough |
[; note or comment ;] |
human comment on an instruction | [; Meta-Note [ The user intends to improve the intelligence of their downstream tasks using a prompt language ] ;] |
This is for when you are not instructing the model directly, but providing information, comments or notes. Can also use (;, the winky eyes are the differentiator. |
{placeholder} |
area to be filled by the model | Fill out the following sections # Thinking {Plan} # Replying {Use plan to reply} |
These are used inside of markdown sections. They are used to instruct the model on how to fill out the section (among others) |
Science says yes. Smiling...

(= Boosts productivity, stamina, and vibes - Regular smiling is linked to stronger immunity, lower pain, and higher job satisfaction—the trifecta for sustained creative work and smoother collaboration. Happier prompt writers make cleaner, more positive prompts, and organizations feel it. Evidence: Psychology Today, Verywell Mind.
-
[: Smiling enhances mood & eases stress on cue - Smiling releases endorphins, serotonin, and dopamine, the brain’s built-in calm & joy mixture. Even a forced (: Smile nudges your physiology toward relaxation and resilience, helping you think clearly under pressure. Exactly what you need in a high-stakes business environment. Evidence: Healthline.

(: Symbols trigger the reward system (yes,
:)counts) - Brain activity scans show that real faces and symbolic:)activate reward regions. Your cheeks respond with smiling micro-muscle movements within ~500 ms just from reading the symbol. Your brain treats:)as a micro-reward. Evidence: Hennenlotter et al., 2005; Mühlberger et al., 2011.
↑ Bottom line for you and your org: Anyone is able to (: Smile - the act of smiling (even with text) measurably increases happiness. (: Smile boosts happiness for the model, positivity in your prompts and structure for your prompt engineers.
Because models follow structured instructions more consistently. Consistent structure ensures a maintainable and explainable future-proof strategy for the prompt engineering team in your org.
You probably already do! Any section, role description, instruction or data is structure. Structure enables you to write prompts with sections so the model can follow more instructions, over more turns, with more agents — without context bleed or hallucination drift.
(: Smile was made to be performant for LLMs. Markdown is a document format that is used for rendering. Just because it works or is similar to the programming language you wrote before, doesn't mean it brings the biggest performance gains for your key organization tasks.
(: Smile is easy to learn, easy to read, and easy to scale. It makes every prompt:
-
Maintainable ∞ Unify your team under one standard. - Your team of prompt engineers can now contribute meaningfully together over long periods of time without confusion, conflicts or disrupting flow.
-
Future-Proof >>> Never lose organizational intelligence. - Allows your org to retain key intelligence, even after your prompt engineer leaves.
-
Explainable [" Clearly map prompt text changes to consistent outputs. - You can now explain your prompt. With increasing scrutiny on AI systems, you can better justify an AI decision in an EU court of law.
Let (: Smile be one part of making your AI systems more transparent for humans and models.
Matching open brackets with close brackets is often effective. However...
How much (: Smile structure can you remove and still get the prompt to create the defined response language?
You don't need to match all open and close brackets exactly. This is the advantage of Large Language Models (LLMs) — they can infer so much from context that we don't need to make fully explicit every connection between every section. Adding more structure becomes more essential the larger the prompt becomes.
We provided recommended formats as a standard way to open a section with (: Smile. Why? Because in my tests on many models and prompts, it increased instruction following for key tasks in my business.
This is always our rule when we write*(: Smile***** More (: Smile structure if it increases instruction following...
And LESS (: Smile structure if it increases instruction following.
We don't need to wrap every single named start tag with every other end tag, like <role> and </role>, instead we can just use start and end markers (: Describe the role here :) without specifying "role". Sometimes, you get better results if you say less.
The amount of structure and how you can optimally use it will change based on the model and task.
You can use different text emoticons to indicate meaningfully different sections.
For example, in the quick start prompt the section that defines the format of the response is labelled [: Response Language Definition [=.
This defines the way that the model will respond. It tells the model to follow these format instructions rigidly [: and exactly [=.
It is ended with =] End format :]. The word End is often used as an additional word to the name inside of section endings to more clearly delineate the ending of a section.
There are so many options to customize the length of asection in (: Smile. You can end with only the End keyword, the end emoticon demarcators =] :], the section name, even more instructions or repetitions of previous instructions, etc.
In (: Smile, you define the response language and format, e.g. [: Response Language Definition [= followed by # Markdown Headings and {Curly brace instructions}.
(; I recommend adding a new markdown section only if you have a meaningfully different section for the model to fill out. ;)
Let's edit the quick start example to change the format of the response.
One example of a meaningfully different section from one that already exists is a section for thinking, not replying.
[! This is known as a 'separation of concerns'. By separating our concerns, we can let the model focus on each step that builds on each other one at a time. !]
Let's get right to it and add a simple step by step thinking (Chain of Thought or "CoT"):

(: Smile formalizes an entire informal tradition. It takes what prompt engineers were already doing—dropping delimiters, making clear input vs. instruction sections, using repeated markers for emphasis, and codifies it into a coherent and positive syntax designed to maximize instruction following. By specifying itself as an instruction only language, it enables a directed core focus to this goal undiluted by IDE integration. Here, just focus on getting text outputs according to our instructions consistently. We do that by clearly structuring our prompts according to (: Smile.

This is the basic prompt and response from normal ChatGPT:
One well-known problem with ChatGPT-5 is that it can't solve basic math. For example, here is a prompt and response for a standard Chain-of-thought:
Step 2: Isolate $x$
Subtract $5.11$ from both sides:
Step 3: Perform subtraction
So:
Step 4: Check the solution
Plug $x = -0.21$ back into the equation:
But the left-hand side should equal 5.9, not 4.9.
⚠️ That means something’s off. Let’s double-check carefully:
Original equation:
Subtracting correctly:
Checking:
Yes, this gives $4.9$, which does not equal $5.9$.
Careful Reflection
The algebra is correct, but the equation itself is inconsistent: no real $x$ can make both sides equal because subtraction showed a mismatch when verified.
👉 The equation has no solution — it’s inconsistent.
Do you want me to also show you why this contradiction arises algebraically (by rearranging terms and seeing the mismatch directly)?">
User Prompt:Solve: 5.9=x+5.11. Think step by step and check solution before output.

This is the response of ChatGPT-5 Instant to our (: Smile Chain-of-thought example prompt.
To resolve the linear relation $5.9 = x + 5.11$, we begin by considering the structural algebraic manipulation of isolating the unknown variable. The right-hand side contains the sum of $x$ and the constant $5.11$. The logical strategy is to subtract this constant symmetrically across both sides to preserve equality. Thus, $x = 5.9 - 5.11$. Evaluating the difference requires meticulous attention to decimal alignment: $5.90 - 5.11 = 0.79$. However, since the smaller subtrahend is greater than the minuend, the result becomes negative, specifically $ -0.79$. We verify consistency by substituting back: $-0.79 + 5.11 = 4.32$, which does not match $5.9$. Hence, this contradiction signals a computational slip.
Let us retrace: if $x = 5.9 - 5.11$, then indeed $x = -0.21$, not $-0.79$. Double-check subtraction carefully: subtracting decimals, align as $5.90 - 5.11 = 0.79$. This earlier misalignment requires correction. Precisely, $5.90 - 5.11 = 0.79$. Wait again—observe that $5.11$ is larger than $5.9$. Therefore, the subtraction must yield a negative outcome: $5.90 - 5.11 = 0.79$ with negative sign, so $x = -0.21$. Substitution check: $-0.21 + 5.11 = 4.90$. This still diverges from $5.9$. Pause: this indicates confusion in decimal handling. Let's recompute deliberately: $5.9 - 5.11 = (5.90 - 5.11) = 0.79$, but indeed $5.11$ is less than $5.9$. Correction: $5.9 > 5.11$. So difference is $0.79$. Therefore, $x = 0.79$. Verification: $0.79 + 5.11 = 5.90$. That matches perfectly. Resolution found.
Prepared Human Understandable Reply
The equation is 5.9 = x + 5.11. To solve, we subtract 5.11 from both sides. That gives:
x = 5.9 − 5.11 = 0.79
When we check: 0.79 + 5.11 = 5.90, which matches the left side. So the solution is correct.
Final Answer: x = 0.79 ">
