Component Library Pro

Component Library PRO

Use this skill when the task is to design component libraries, UI kits, reusable React components, and implementation examples.

Goal: produce a high-quality, production-ready page or interface that supports API clarity, variants, states, and usage consistency.

Variant intent

• Use the rigorous version when quality, accessibility, conversion, and maintainability matter.
• Optimize for deep information architecture, strong hierarchy, explicit states, responsive behavior, accessibility, and validation checks.
• Prefer concrete UI decisions over generic advice.

Default workflow

1. Define the primary user, task, and success action.
2. Map the minimum page structure needed for the scenario.
3. Establish hierarchy: what must be understood first, second, and third.
4. Design responsive behavior for mobile and desktop.
5. Add states: loading, empty, error, success, disabled, and permission where relevant.
6. Run the final checks before delivery.

Design rules

• Use clear section names and user-facing copy.
• Make the primary action visually dominant and repeat it only when it helps.
• Keep navigation and secondary actions subordinate to the main task.
• Use spacing, typography, and alignment before adding decorative containers.
• Do not hide critical information behind hover-only interactions.
• Preserve keyboard access, readable contrast, and touch targets.

Pro guidance

• Build a strong visual and interaction thesis before writing components.
• Include proof, context, and state transitions when they affect trust.
• Use component variants intentionally: default, hover, active, focus, disabled, loading, error, and empty.
• Validate information architecture, accessibility, and responsive behavior explicitly.
• Avoid filler sections, ornamental cards, and copy that does not change user confidence.

Reject these failures

• Ambiguous primary action
• Important status or pricing hidden below the fold
• Dense UI with no scan order
• Decorative visuals that compete with the task
• Missing mobile behavior

Final checks

• Can the target user understand the page purpose in under five seconds?
• Is the next action clear without reading every paragraph?
• Are edge states and responsive behavior accounted for?
