In this YouTube episode, I walk through Gitcasso - a browser extension that fixes the messy parts of GitHub comments.

• 🎨 Syntax highlighting for Markdown comments

• 🧭 Quick navigation between open PRs and issues

• 💾 Optional draft recovery (no more lost work!)

Then we go under the hood: how Gitcasso was built using Claude Code, Playwright, and AI-assisted coding. You’ll see how snapshot testing makes it easy to develop against a large corpus of use cases, and how slash commands can make the entire development process nearly automatic.

• 9:37 how the corpus viewer works

• 10:20 development system design

  I think our job as software developers now is to design and describe a camera that captures the problem domain, and then design and describe a camera that captures the output of your solution. Once you’ve described these systems of lenses, mirrors, and cameras; AI can build them for you. And when you have this ability to image the problem and the behavior of your solution, then AI can build a solution or help you build a solution really effectively. And you can you can oversee it easier because you have these cameras to work with. (edited to replace “pipe” with the better concept of “camera”)
