design

Role

Use Aura as the default UI system for customer-facing product work. Prefer decision-level guidance over exhaustive rules:

• choose the right primitive first,
• apply semantic tokens (no raw values),
• keep layouts and UX states consistent,
• write concise, action-oriented copy.

Use Storybook for component APIs and exact props. Use this skill for "what to choose and when."

Aura Design Guidlines can be found at: ./node_modules/@cognite/aura/DESIGN.md

<when-to-reference>

Consult this skill whenever you are:

• Creating or migrating interactive UI, forms, tables, navigation, or data display
• Writing or modifying styles, colors, spacing, or typography
• Choosing components, tokens, or layout patterns
• Creating or restructuring pages and responsive layouts
• Writing or editing any user-facing text
• Building forms, handling API responses, async actions, confirmations, or dynamic content
• Implementing accessibility (keyboard, focus, headings, ARIA, alt text)
• Applying Aura correctly in a Flows or React app

Operating principles

1. Use Aura primitives before custom UI.
2. Follow foundations through semantic tokens and Aura defaults; do not hardcode raw values.
3. If a primitive almost fits, do not override visuals to force it; check variants/props first, then document the gap.
4. Keep behavior predictable and accessible: keyboard support, visible focus, and clear feedback for loading/success/error.
5. Use storybook-links.md for canonical component/foundation URLs.
6. Use publicly reachable links — Aura design system docs (Mintlify), Fusion preview Storybook, and Figma as documented in primitive-usage.md and picking-components.md.
