In the spirit of 12 Factor Apps. The source for this project is public at https://github.com/humanlayer/12-factor-agents, and I welcome your feedback and contributions. Let’s figure this out together!
AI is transforming the way we work — automating production, collapsing handoffs, and enabling non-designers to ship work that once required a full design team. Like it or not, we’re heading into a world where many design tasks will no longer need a designer.
“These questions feel really personal”; ”This is going to be too controversial”; “You should stick to programming surveys”.
New research backs up what gamers have thought for years: video games can be an antidote to stress and anxiety.
Your first step is to define that job in a single sentence. This isn’t just a nice-to-have, it’s your design compass. It makes priorities obvious and tradeoffs easier to navigate.
But that was AI, before APIs that bill you for every little thing, before people subscribed to tools they don’t even remember signing up for, before you could hit $10M ARR in a year and still have no idea if your product will stick.
What if you could design and build on the same canvas? Here’s how we created code layers to bring design and code together.
When you hear “whiteboard,” the first thing that probably comes to mind is a classic brainstorming session filled with sticky notes, doodles, and scattered ideas.
The Müller-Lyer illusion, pictured below, makes you think that, of two lines, one is longer than the other when in fact they are of the same length. It appears in virtually every introductory book on graphic design and, of course, in books on perception and psychology. You might not have known it by name, but you must have seen it before:
Chrome 137 shipped the if() CSS function, so it’s totally possible we’ll see other browsers implement it, though it’s tough to know exactly when. Whatever the case, if() enables us to use values conditionally, which we can already do with queries and other functions (e.g., media queries and the light-dark() function), so I’m sure you’re wondering: What exactly does if() do?
