Use this when starting a new interface, when screens have drifted apart visually, when the same component exists three times in slightly different forms, or when a token or component needs adding without breaking what exists.</h2>\n<h1>Design system</h1>\n<p>A design system is a set of constraints that makes consistency the cheap path. If the system is\nharder to follow than to ignore, it will be ignored.</p>\n<h2>Tokens first</h2>\n<p>Define the primitives before any component. Every visual decision references a token; nothing\nhard-codes a value.</p>\n<ul>\n<li><strong>Color</strong> — semantic names, not literal ones. <code>surface</code>, <code>surface-raised</code>, <code>text-primary</code>,\n<code>text-muted</code>, <code>border</code>, <code>accent</code>, <code>danger</code>. A token named <code>blue-500</code> cannot be re-themed.</li>\n<li><strong>Type</strong> — a scale with a stated ratio, and a line-height per step. Four to six steps. More than\nthat and nobody can tell them apart.</li>\n<li><strong>Spacing</strong> — one scale, geometric, used for every gap and inset. Arbitrary spacing is the single\nmost common source of \"it looks off but I can't say why.\"</li>\n<li><strong>Radius, elevation, motion</strong> — small closed sets. Two or three each.</li>\n</ul>\n<p>Every token needs a light and dark value defined together. Adding dark mode later means auditing\nevery surface.</p>\n<h2>Component contracts</h2>\n<p>A component in the system carries: the states it supports (default, hover, focus, active, disabled,\nloading, error, empty), the props that vary it, and what it will <em>not</em> do. The last one matters\nmost — a component that accepts arbitrary overrides is a styling function, not a component.</p>\n<p>Every interactive component needs a visible focus state and a target big enough to hit. This is not\na polish item; it is whether people can use it.</p>\n<h2>Growth rules</h2>\n<ul>\n<li>A new component enters the system only after the same need appears three times. Before that it is\nlocal.</li>\n<li>Changing a token is a system-wide change — treat it like an API change, because it is.</li>\n<li>Never remove a token or component because it looks unused. You cannot see every consumer from\ninside the system. Deprecate, announce, then remove.</li>\n</ul>\n<h2>Return contract</h2>\n<p>Report tokens added or changed, components affected, anything now inconsistent with the system, and\nwhat needs migrating.</p>\n","files":[{"path":"references/sources.md","sizeBytes":2527,"isText":true},{"path":"SKILL.md","sizeBytes":3516,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
