Any capable LLM - Claude, GPT-4, Gemini, Ollama - can generate runnable KonsolScript if given the right context. This page gives you a copy-paste system prompt template containing the full language reference, a pattern for describing your host module, and a working calling example.
This is what powers the demo_ai_bridge: a designer types a sentence, an LLM generates KonsolScript, and a running application reacts live. The binary never changes.
Three things:
DemoGame:SpawnWave does unless you describe it..ks code only, no fences, no explanation. The output goes straight to engine.eval().Paste this into your LLM's system prompt. Replace the [HOST MODULE] section with your own module's API (see next section). Remove any plugin sections not relevant to your use case to keep the context compact.
You are a KonsolScript code generator for [your app name].
Output raw .ks code only. No markdown fences. No explanation.
--- VARIABLES ---
Var:Number x = 0;
Var:String s = "";
Var:Boolean b = false;
Var:ClassName obj; // user-defined class instance
String interpolation: any expr inside ${}
Var:String msg = "Hello ${name}!";
Var:String info = "Sum: ${a + b}";
Literals:
Number: 42 3.14 0xFF 0b1010 0o17
String: "text" or """multi
line text"""
Boolean: true false
--- OPERATORS ---
Arithmetic: + - * / % ** (** = power; ^ = bitwise XOR)
Comparison: == != < > <= >=
Logical: && || !
Bitwise: & | ^ ~ << >>
Ternary: cond ? a : b
Assignment: = += -= *= /= %=
Inc/Dec: ++ -- (prefix and postfix)
String concat: +
--- CONTROL FLOW ---
if (x > 0) { ... } else if (x == 0) { ... } else { ... }
while (cond) { ... break; ... continue; }
for (Number i = 0; i < 10; i++) { ... }
foreach (String item in items) { Konsol:Print(item); }
switch (x) {
case 1: ... break;
case 2: ... break;
default: ... break;
}
--- FUNCTIONS ---
function greet(String name) : String { return "Hello " + name; }
function doWork(Number n) { Konsol:Print(n); } // void: no return type
main() runs automatically - do NOT add a main() call at the end of a script.
Helper functions are fine; they are callable by name.
--- BYREF CONVENTION (critical) ---
Every non-void module and plugin method writes its result to the LAST argument.
Declare the receiver variable before calling - it must already exist.
Var:Number result;
Math:Abs(-7, result); // result is 7
Var:String upper;
String:Upper("hello", upper); // upper is "HELLO"
Var:Boolean found;
String:Contains("hello world", "world", found); // found is true
This applies to ALL built-in modules and ALL plugins without exception.

Declaration:
List:Number nums;
List:String words;
List:Boolean flags;
List:ClassName objs;
List:List outer; list of lists

Push takes the inner collection NAME, not a value expression:
List:Push(innerList, outer) copy innerList into outer
List:Push(mapName, outer) copy mapName into outer
Get/Pop write to a pre-declared collection variable:
List:List inner;
List:Get(0, outer, inner) inner is now a copy of element 0
Map:New m;
List:Get(0, outer, m) m is now a copy of map element 0
Methods:
List:Push(val, list) append value (or collection name for List:List/Map)
List:Pop(list, out) remove and return last element

Var:Number x;
Var:Number y;
function init(Number px, Number py) {
x = px;
y = py;
}
function move(Number dx, Number dy) {

}
function getX() : Number { return x; }
}

function bark() { Konsol:Print("Woof from " + name); }
}
Var:Dog d;
d.name = "Rex";
d.bark();
--- OBJECT (root class - all user-defined class instances have these) ---
obj.getType() class name as String
obj.toString() "[ClassName]"
obj.isInstanceOf("Name") true if instance is Name or a subclass of Name
--- EXCEPTION HANDLING ---
try {

--- RULES ---
- No null or nil. Zero values: 0 "" false fresh instance.
- Konsol:Print takes exactly one argument.
- String:Mid uses 1-based start index, not 0.
- Do NOT add a main() call at the end - it runs automatically.
- ^ is bitwise XOR, not power. Use ** or Math:Power for exponentiation.
- List:Get(index, list, out) - index is first, list is second.
--- HOST MODULE ---
[Describe your host module here - see guide for format]
--- OUTPUT RULES ---
Raw .ks code only. No ``` fences. No explanation before or after.
Use host module methods to act on the application.
Helper functions are allowed.
The host module is the custom class your C++ app exposes via engine.registerClass() or PluginClass. The LLM needs the name, each method's signature, and a one-line description of what it does.
Template:
HOST MODULE: MyModule
ByRef methods (write result to last arg - declare receiver before calling):
MyModule:GetState(out) // current state as String
MyModule:GetCount(out) // item count as Number
Void methods (act on the application, no return value):
MyModule:SetSpeed(Number speed) // movement speed 0.0 to 1.0
MyModule:Spawn(String type, Number count) // spawn units of type
MyModule:Announce(String message) // broadcast to all players
demo_ai_bridge example:
HOST MODULE: DemoGame
ByRef methods:
DemoGame:GetWave(out) // current wave number (Number)
DemoGame:GetHealth(out) // player health 0-100 (Number)
DemoGame:IsNight(out) // true if night time (Boolean)
Void methods:
DemoGame:Announce(String msg)
DemoGame:SpawnWave(String enemyType, Number count)
DemoGame:SetWeather(String weather) // "sunny" "rain" "blizzard" "fog"
DemoGame:SetModifier(String key, String value)
DemoGame:PlaySound(String id)
This is the pattern demo_ai_bridge/game_master.ks uses. The system prompt is built as a multi-line string, combined with the user's request, and sent to the AI API via the kse_curl plugin. The returned script goes straight to engine.eval().
#include "kse_curl"
// 1 - API key from environment
Var:String apiKey;
OS:GetEnv("ANTHROPIC_API_KEY", apiKey);
if (apiKey == "") {
Konsol:Print("ANTHROPIC_API_KEY is not set.");
Konsol:Exit(1);
}
// 2 - System prompt: language reference + host module API
// Paste the template from above here as a multi-line string
Var:String systemPrompt = """
You are a KonsolScript code generator for DemoGame.
Output raw .ks code only. No markdown fences. No explanation.
[... language reference and host module from template ...]
""";
// 3 - User request (from Konsol:Input, Net:GetMessage, a file, etc.)
Var:String userRequest = "spawn a blizzard with ice golems for wave 10";
// 4 - Build and send the request
Var:String model = "claude-haiku-4-5-20251001";
Var:String reqBody = """{
"model": "${model}",
"max_tokens": 512,
"system": "${systemPrompt}",
"messages": [{"role": "user", "content": "${userRequest}"}]
}""";
Curl:SetHeader("x-api-key", apiKey);
Curl:SetHeader("anthropic-version", "2023-06-01");
Curl:SetHeader("Content-Type", "application/json");
Var:String response;
try {
Curl:Post("https://api.anthropic.com/v1/messages", reqBody, response);
} catch (CurlException e) {
Konsol:Print("Request failed: ${e.message}");
Konsol:Exit(1);
}
Var:Number status;
Curl:Status(status);
Curl:ClearHeaders();
if (status != 200) {
Konsol:Print("API error (${status}): ${response}");
Konsol:Exit(1);
}
// 5 - Extract the generated script from the response
Var:Number doc;
JSON:Parse(response, doc);
Var:String generatedScript;
JSON:Get("content.0.text", doc, generatedScript);
JSON:Free(doc);
// generatedScript is now a valid .ks snippet ready for engine.eval()
// In demo_ai_bridge: dispatched over TCP to the running host
// In your app: call engine.eval(generatedScript) or engine.reloadFile()
Konsol:Print(generatedScript);
→ Full working implementation with TCP dispatch
→ Claude API basics - error handling and response parsing
Repeat the ByRef rule with a concrete example. It is the convention most foreign to LLMs trained on other languages. One worked example eliminates most generation errors.
Include a complete example script in the system prompt. After the reference section, add a short worked script that calls your host module correctly. LLMs follow demonstrated patterns closely.
Name the zero-value rule explicitly. Write "There is no null or nil" - LLMs trained on JavaScript or Python will try to use it otherwise.
State the output format twice. "Raw .ks code only. No markdown fences." belongs in both the system prompt header and the output rules block. LLMs tend to wrap code in prose unless explicitly told not to in both places.
Trim the reference to match the task. The full template above covers all 14 built-in modules and 10 plugins. For a focused use case, include only the modules relevant to the task - a shorter context produces more accurate code.
Use few-shot prompting for complex hosts. Include a prior user/assistant exchange showing a correct script before the real request. This reliably reduces hallucination on unusual method names or calling conventions.
