I wrote the spec. An agent wrote the code. Most of my time went on deciding which of its suggestions were wrong.

The spec lives at the root of the repo as CLAUDE.md — tokens down to the hex, component contracts, a phase list where nothing starts until the previous thing passes its check. It took longer to write than the first few pages took to build, which sounds like bad maths until you've watched an agent confidently invent a component library nobody asked for. The specificity is the job. Vague instructions still get you vague software, just faster than before.

The method is the one I teach: stream, structure, build, test. Dump everything, let a model turn the mess into a brief, argue with the brief until it's small enough to be true, then build one testable thing at a time. So the four-phase diagram on my CV isn't a retrofit — it's what produced the CV. The palette you're looking at is the second one, incidentally. The first was monochrome and sharp-cornered and I liked it right up until I put it next to something warm.
