Opinions, written down.

KB Development is a small practice built around a belief that the interesting problem in AI engineering is no longer the model — it is the system around it, and the workflow that produces that system.

Work starts from a specification rather than a prompt. Decisions get written down where the next person can find them, with the reasoning attached, because an architecture nobody can reconstruct is a liability regardless of how well it performs today.

The same standard applies to the visual layer. Colour roles carry measured contrast ratios, tokens are tested, and the rules that are easy to get wrong are documented as rules — not left in someone's head.
