Context is the bottleneck for coding agents now

Can you show something you have built with that workflow?

Of course not.

Not yet unfortunately, but I'm in the process of building one.

This was my journey: I vibe-coded an Electron app and ended up with a terrible monolithic architecture, and mostly badly written code. Then, I took the app's architecture docs and spent a lot of my time shouting "MAKE THIS ARCHITECTURE MORE ORTHOGONAL, SOLID, KISS, DRY" to gpt-5-pro, and ended up with a 1500+ liner monster doc.

I'm now turning this into a Tauri app and following the new architecture to a T. I would say that it is has a pretty clean structure with multiple microservices.

Now, new features are gated based on the architecture doc, so I'm always maintaining a single source of truth that serves as the main context for any new discussions/features. Also, each microservice has its own README file(s) which are updated with each code change.

I vibe coded an invoice generator by first vibe coding a "template" command line tool as a bash script that substitutes {{words}} in a libre office writer document (those are just zipped xml files, so you can unpack them to a temp directory and substitute raw text without xml awareness), and in the end it calls libre office's cli to convert it to pdf. I also asked the AI to generate a documentation text file, so that the next AI conversation could use the command as a black box.

The vibe coded main invoice generator script then does the calendar calculations to figure out the pay cycle and examines existing invoices in the invoice directory to determine the next invoice number (the invoice number is in the file name, so it doesn't need to open the files). When it is done with the calculations, it uses the template command to generate the final invoice.

This is a very small example, but I do think that clearly defined modules/microservices/libraries are a good way to only put the relevant work context into the limited context window.

It also happens to be more human-friendly, I think?

I "vibe coded" a Gateway/Proxy server that did a lot of request enrichment and proprietary authz stuff that was previously in AWS services. The goal was to save money by having a couple high-performance servers instead of relying on cloud-native stuff.

I put "vibe coded" is in quotes because the code was heavily reviewed after the process, I helped when the agent got stuck (I know pedants will complain but ), and this was definitely not my first rodeo in this domain and I just wanted to see how far an agent could go.

In the end it had a few modifications and went into prod, but to be really fair it was actually fine!

One thing I vibe coded 100% and barely looked at the code until the end was a MacOS menubar app that shows some company stats. I wanted it in Swift but WITHOUT Xcode. It was super helpful in that regard.
