AICode - AI generating code engineered for long-term maintainability.

AI coding agents generate code fast, but large applications quickly become hard to maintain. AICode is a VSCode extension powered by ChatGPT and built around a controlled AI development methodology: Ideate → Specify → Refine → Code → Verify. It prioritizes architecture and review before generation. It is slower than autonomous agents, but far faster than coding without an AI and produces structured, maintainable software built for real long-term projects.

This is a methodology I created and perfected using ChatGPT.com, directly on their webpage. I had a set of pre-defined prompt pieces in a notepad that I assembled manually to have the AI generate my code. I then added constraints in ChatGPT settings and refined the prompts and methodology: specifications, self-checks before coding, and checks after coding. Once this manual system became efficient through trial and error, I transferred the system prompt, the prompts, and the methodology into a software package: a Visual Studio Code extension: AICode. Now I publish this extension and methodology. I use it in my own work and can write and maintain a 500K LOC app with pure vibe coding.
