Pre(r)amble

This is part of a series of posts documenting some of the process of (building|cat herding an AI agent to build) Clipy, an easily hosted Python teaching tool built with just front-end JS and a WASM port of MicroPython.

You can find the GitHub repo for the project here

I keep a relatively up to date version here if you want to try it

What we had before

Last week was mostly about fixing up issues with implementation methods.

Last week was adding the record-replay feature (lots more about that this week, what a rabbit hole) and putting in nicer file management (which still needs some tweaks, but I’m pretty happy with it).

I have a (somewhat) up to date version of this tool running on the site. Things might occasionally be broken, things might not work the same way as they did before.

This week I was really excited about getting the Abstract Syntax Tree feedback and testing working, as well as just tightening up the user experience a bit, hiding knobs and dials when they weren’t used, etc. I’m getting close to the end of my initial feature list!

The outcome of the previous week’s achievements was pretty satisfying since I’d tried and failed to solve the problems of having a responsive WASM Python runtime for user code before. Being able to lean on the agent to do things like make changes to C code where I knew what the outcome needed to be, and knew how it needed to work, but didn’t know what to do to make it happen was so valuable.

I’m in a strange place in my head with respect to coding agents. On one hand I see all the really dumb stuff that “intelligent” chatbots produce, on the other hand, I’ve used them myself to turn something from “I should do that sometime when I’m motivated” into something I can actually use. It’s a weird time to be a teacher, let alone one of Digital Technologies.

Anyhow, this post (and hopefully some future ones) is an attempt to use AI to help shift some projects out of my head and backlog, and try and get them made. I’m aware of some of the things I found with my first AI coding experiment, in that rather than necessarily turning me into a “10x Engineer”, in fact it can turn me into a “0.95x Engineer”, getting me 95% of the way there and then getting stuck. The wonderful Cory Doctorow had a turn of phrase “reverse centaur” in this post, referring to when humans are forced to use AI. I loved the term, but probably not for the reason it was intended. I feel that when you’re being a centaur using AI agents, sometimes you’re the human, and sometimes you’re the horse(’s arse).
