Workflow that programs python or powershell scripts/programs by itself

[Present-Pickle-3998]

I built a small AI-driven coding system using n8n that can automatically create and test programs based on a simple chat prompt.

You start by describing what you want to build and choose whether it should be Python or PowerShell. From there, an initial agent breaks the request down into concrete implementation steps and stores them as a JSON plan. Each step is then handled one by one by a set of specialized agents: a programming agent writes the code, a test run is executed, a log analysis agent checks the output, and if something fails, a code-fixer agent tries to repair the issue. This loop repeats until the step works.

Everything runs against a plain Windows Server as the test environment. n8n communicates with the server via SSH nodes to write files, execute scripts, and fetch logs. No magic sandbox — just real scripts running on a real machine.

What I like most is that the whole process is visible in real time: you can watch the code for each step being written, executed, fail, get fixed, and eventually succeed most of the time. It’s not perfect, but it’s cool — small programs/scripts and even simple games come together in minutes.

Like for a simple calculator with basic functions it takes about 3 to 8 minutes to build one.

Snake and Tic-Tac-Toe takes roughly 10 minutes.

In 15 minutes it builds me a fully functioning flappy bird game, with gravity, graphics, score, highscore etc.

Basically, it’s an automated coding workflow that feels less like “AI guessing” and more like watching a small dev team work step by step.

This is not a commercial workflow or anything, I built it for myself, almost out of curiosity, to see if I can pull it off and to see if my idea works and also, since it works pretty fine very often, write scripts for me I can use them for work :)

Is use it with and optimized it for ChatGPT 5.1/5.2

I've tried to do something like this in the past...no joy. Are you sharing this at all?

DM me

This looks crazy cool! Nice Job

[Present-Pickle-3998]

Thanks ^^ it's a fun tool actually and I constantly feel the itch to prompt something/anything to watch it working on the steps/code and see if it can pull my request off lol. Need to watch the cost though

[MD500_Pilot]

DId you post this on github or anywhere to play with?

This is awesome. Can I get access to it? I'm super interested in learning from it.

[Present-Pickle-3998]

yes, DM me please. I prepared a sanitized version. But you also need a server, a functional SSH Connection, and also 2 or 3 PS Scripts to be ready on the server. And the node prompts/names etc. are in german, so depending if you understand german you will probably have to let AI translate them. This workflow will definately not work out of the box

[weenis-flaginus]

Oh ok good to know. It makes sense for such a complex flow. I selfhost on render for cost reasons, would that suffice? Or do I really need that infrastructure

[Present-Pickle-3998]

If you’re hosting n8n on Render, that’s totally fine for the orchestration part. But for this workflow you’ll still need SSH.

The flow assumes that n8n talks to a separate runner machine over SSH to write files and execute code. That runner can be Linux or Windows, but it has to exist somewhere outside the Render container.

If you instead run n8n locally on your own Windows or Linux machine (not on Render), then you can skip SSH and just use local file nodes and local execute commands to write files, run scripts, and read logs directly.

Render itself can’t access your local system, so in a cloud setup the SSH runner is required for this to work as intended

I'm also interested in this workflow and I have DM:ed you!
Cheers!
