Stage 1: Analysing what’s out there
The first thing I did was pull apart a bunch of existing files — both hand-crafted ones and the scraped collections circulating on GitHub. Some of them are pretty decent, others – questionable.

The pattern was immediate. Almost every underperforming file starts the same way: with a colour palette. No context before the first hex code. No sense of what the product does, who uses it, or what a good decision looks like in this specific context.

What you get is description — here’s what the system looks like. What a model actually needs is constraint — here’s what the system permits, what it forbids, and what to do when it hits a situation you didn’t anticipate.

Those are different writing tasks. And treating them the same way is why most files produce mediocre output.
