+title: "Improve Your Code Twice with GenAI 🛠️"
+authors: genaiscript

+draft: true
+tags: ["genai", "code improvement", "automation"]

+
+## Introduction
+
+Have you ever wished to improve your code automatically? This script uses GenAI to enhance your code by running a specific function twice. You can view the script [here](https://github.com/microsoft/genaiscript/blob/main/packages/sample/genaisrc/makeitbetter.genai.mjs).
+
+## Motivation
+
+The goal of this script is to leverage artificial intelligence to analyze and enhance your code without manual intervention. It's like having a smart assistant that can refine your work effortlessly.
+
+## Code Explanation
+
+Let's walk through the script line by line:
+
+```js
+import { makeItBetter } from "genaiscript/runtime"
+```
+This line imports the `makeItBetter` function from the GenAIScript runtime. This function is used to improve code by repeating a set of instructions multiple times.
+
+```js
+def("CODE", env.files)
+```
+This line defines a constant named "CODE" that represents the files in the environment. It essentially sets up the context for the code that needs improvement.
+
+```js
+$`Analyze and improve the code.`
+```
+This line is a prompt for the AI model. It instructs the system to analyze and enhance the code. The `$` is used to denote that this is a special instruction, not a regular code command.
+
+```js
+// tell the LLM to 'make it better' 2 times
+```
+This comment explains the upcoming line of code, making it clear that the `makeItBetter` function will be called twice.
+
+```js
+makeItBetter({ repeat: 2 })
+```
+This line calls the `makeItBetter` function with an option to repeat the improvement process twice. It triggers the enhancement process.
+
+## How to Run the Script
+
+To run this script using the GenAIScript CLI, you need to execute the following command in your terminal:
+
+```bash
+genaiscript run makeitbetter
+```
+
+For detailed instructions on installing and setting up the GenAIScript CLI, check out the [GenAIScript documentation](https://microsoft.github.io/genaiscript/getting-started).
+
+By following these simple steps, you can harness AI to make your code better with ease! 🌟

+
+Surprising results happen when you repeatidely ask the LLM to "make it better" (see [blog post](https://minimaxir.com/2025/01/write-better-code/)).
+
+In this sample, we use the `makeItBetter` function from the `genaiscript/runtime`
+to acheive exaclty that: asking the LLM to make it better for a few rounds.
+
+## Code Explanation
+
+Let's walk through the script line by line:
+
+```js
+import { makeItBetter } from "genaiscript/runtime"
+```
+
+This line imports the `makeItBetter` function from the GenAIScript runtime. This function is used to improve code by repeating a set of instructions multiple times.
+
+```js
+def("CODE", env.files)
+```
+
+This line defines a constant named "CODE" that represents the files in the environment. It essentially sets up the context for the code that needs improvement.
+
+```js
+$`Analyze and improve the code.`
+```
+
+This line is a prompt for the AI model. It instructs the system to analyze and enhance the code. The `$` is used to denote that this is a special instruction, not a regular code command.
+
+```js
+makeItBetter({ repeat: 2 })
+```
+
+This line calls the `makeItBetter` function with an option to repeat the improvement process twice. It registers a [chat participant](/genaiscript/reference/scripts/chat-participants)
+that injects messages in the chat conversation loop.
+
+The `makeItBetter` rouhgly looks like this. It registers a callback function that gets called
+on every chat turn.
+
+```js
+export function makeItBetter(options?: { repeat: ... }) {
+    let round = 0
+    defChatParticipant((cctx) => {
+        if (round++ < repeat) {
+            cctx.console.log(`make it better (round ${round})`)
+            cctx.$`make it better`
+        }
+    })
+}
+```
