A shared design bar,
built into the work.
The DX Design Harness turns product intent, design decisions, and checkable standards into a workflow every team can use. It helps people and agents ship coherent interfaces, with or without a designer on every task.
Start with the harness
Install it once, pick the skill that fits the work, then follow the loop when a change needs design decisions and review.
Standards
Use the control catalogue for enforceable requirements. Use the pages under it (writing, colour, typography, motion, and the rest) when the work needs judgement.
Standards
The must layer. Checkable rules that bind every screen you ship, human-built or agent-built.
12 pages
Writing
Not written to be read. Written to be acted on.
Colour
Colour tells people which product they're in and what needs their attention. Each product keeps its own primary; neutrals and status colours stay shared.
Typography
Type sets the hierarchy a tired reader scans first: what's a heading, what's next, what can wait. Your DESIGN.md names the fonts, their roles, and the scale.
Motion
Motion is feedback, not decoration: four durations, two easings, and one rule — nothing moves that doesn't mean something.
