Introducing Clause Code — The Christmas Themed Coding Agent That You’ve Been Waiting For – About Things

Part of riding the Generative AI wave is learning how to build my own tools. I have been using Claude Code since February, and it occurred to me that I have never built my own coding agent. Anthropic provides all of the pieces of the puzzle: APIs, SDKs, and Python Packages. And since I always try to be funny… I thought it would be funny to create Clause Code… see how funny I am? See!?

So, Clause Code is my attempt to learn the Anthropic SDK and add a little Christmas magic to coding.

Why don’t I just let Clause Code tell you about Clause Code?

Clause Code transforms your coding workflow into a delightful holiday experience. Every interaction features festive ASCII art, and cheerful status messages like “Sleighing…” and “Jingling…” while Claude thinks. It’s like having Santa’s workshop right in your terminal!

Clause Code automatically detects when Claude generates code and extracts it into the right files. Just ask “Create a Flask app with authentication” and watch as it generates and writes app.py, auth.py, requirements.txt and more – all organized in your project folder. No more copy-pasting from chat windows!

Beautiful Syntax Highlighting Code is rendered with rich syntax highlighting using the Monokai theme, making every snippet easy to read and understand. Whether it’s Python, JavaScript, Rust, or any other language, your code looks gorgeous in the terminal.

Clause Code Modes

Santa Mode 🎅 – Full festive experience with maximum holiday cheer (/santa)
Grinch Mode ⚙️ – Minimal, professional output when you need to focus (/grinch)
December Advent Calendar 🎁 – Throughout December, use /advent to unlock daily coding challenges with a festive twist. It’s like an advent calendar for developers – a new challenge each day!

I did learn a lot building this coding agent. For one, I learned how Anthropic is building these cool terminal apps. I totally missed that developers were making terminal apps. I discovered Textualize/rich (https://github.com/Textualize/rich) and other techniques that make the terminal interactive.

How To Use Clause Code

Copy Clause Code to your machine, navigate to that folder, and set your Anthropic API Key
Run the app with uv sync and uv run clause-code
Set a project folder with /project
Send in a prompt

Demo Time

Of course, I am going to make CheerLights project with my very own Clause Code coding agent.

Here’s my prompt:

build a web page that reads the cheerlights color from thingspeak and set its background to it. in the foreground show me falling snow using css.

With a bit of Christmas magic, I will get a webpage that gives me just what I wanted this year for Christmas. Or, maybe have been naughty and using a quantized model at peak hours of the day 😉

CheerLights Webpage Created by Clause Code

Check out the project on GitHub, feel free to make changes, learn something new, and share the joy. Make sure to use it during December and try out the Advent coding challenge feature!
