It was my first time using AI to formalize the rules from an RFC and turn them into testable, working code. That's why I also explicitly say that this tool is not currently in use for production (I'm sure it will contain bugs!), it's just like a tinkering tool for me and at one point I hope to make this into something that people can maybe even use in their production system.
For visualization, I built a hex viewer that shows how the CBOR is decoded. It's really helping me understand the format better.
Right now it's just a basic version—you can encode, decode, and diff two CBOR values. There's still a lot of work to do. I'd like to add more educational content about what CBOR actually is and offer more tools.
I work in the Cardano space where CBOR is used heavily, so one thing I want to add is a function that can recognize which Cardano era a transaction (or part of a transaction) comes from.
There is still a ton of work to do and I have more ideas in mind, but for now that's my first version and I would like to get some feedback :)
The CBOR parser for that project is already open sourced, and I also built a small test suite to validate my CBOR parser against test cases and see how I compare to different parsers. That's why I created two projects that make this app possible. They are both linked in the about page and they're called Nachos and Taco.
