I was working on reading the comments on this post, and got tired of scrolling with the mousepad. I had not used any of the LLMs in a few weeks now and wanted to see how they fared for writing a web extension to let me browse hacker news via arrow keys and the "prev" and "next" comment buttons. My goal was to write 0 lines of code myself and rely solely on copy-pasting(successful in my eyes). ChatGPT 4o disappointed me on getting a final product, but Claude Sonnet blew me away enough to push me to pull out my credit card to subscribe to a pro plan.
All that to say I "worked" on a chrome extension to let you browse a hacker news post via arrow keys: https://github.com/humishum/hacker_news_keys.
(While typing this I found that the arrow key actions are still active while in the textbox, time for claude to provide me a fix!)
