AI

I spent years avoiding fragile, undocumented legacy systems. AI didn't make the code less scary, it made understanding cheap, and that changed everything, including a Slack bot nobody would touch for a year.

Vibe coding gets you a prototype. It doesn't get you a production system. The missing piece isn't a better prompt - it's a structure. AI-Scrum is an experiment in running autonomous agent teams the way good engineering teams have always worked: defined roles, sprint cadence, QA loops and retrospectives that actually feed the next cycle. I ran it on a Node.js home finance project. Some of it worked surprisingly well. Some of it burned tokens on Playwright setup for what felt like forever. This post covers both.
