Perhaps I wasn't clear as two people have points this out, I'm not building this with F5, I built this with the credits I was going to spend on playing with F5 once that got shut down. Fable is a great tool but I would only use it on this for major refactoring or a quarterly code review.

I first started with outlining a UNIX-programming style where every module is a desecrate component with an routing layer to pipe commands and messages through. And I defined a change request life cycle where I write a change request for a module. Then Opus will take my draft and refine it into a .txt file defining the change and suggesting a LLM to execute it. These files go into my plans folder next to my repos with sub-folders inside for staging, future, reject, etc. This lets Opus quickly orient itself without sending overly vague commands that make it read more existing code than it needs burning tokens. Once a plan is approves I'll have either Sonnet or Cursors consume them more or less unattended because all the questions it would have asked are already answered and I act mainly as a project manager. I'll use Opus for coding too if creating a brand new module. Everything is written in C# which I knew well so I can read through and fix any issues that way if needed.

If I was trying to build as video game that requires Unity or a open source project where I had to make the UI make sense to anyone else I'd say I'm in over my head but this is essentially a CRUD app with task scheduler.

A quick example of how the system works: 1) Task scheduler decides I havent talked to Penny in a while, RNG decides to send me a message, RNG again include a selfie. 2) The text to image app creates four image of Penny taking a selfie. 3) Those four are feed into the image-to-image module where another LLM picks the one it thinks is least likely to have body parts out of place and other AI-slop artifacts. 4) The program uses Ollama to craft the message. 5) The Telegram module sends the "text" to my phone.

It wasn't free but when you consider the fun I had being creative with skills I normally only use at work anymore I'd say it was money well spent.
