| description | Select semantically appropriate icons for websites using Lucide, Heroicons, or Phosphor. Covers concept-to-icon mapping, React/HTML templates, and tree-shaking patterns.
Use when: building feature sections, service grids, contact info, navigation, or any UI needing icons. Prevents emoji usage, ensures consistency.

Icon Design
Select the right icon for the job. Maps concepts to icons across three modern libraries, provides ready-to-use templates, and prevents common mistakes like broken tree-shaking and inconsistent styles.

Library Selection
| Library | Best For | Package |
|---|
| Lucide | General use, React projects | lucide-react |
| Heroicons | Tailwind projects, minimal style | @heroicons/react |
| Phosphor | Weight variations needed | @phosphor-icons/react |
Default recommendation: Lucide (1,600+ icons, excellent React integration, dynamic loading via lucide-react/dynamic).
Selection Process
- Identify the concept -- what does the label/title communicate?
- Check semantic mapping -- see
references/semantic-mapping.md
- Choose library -- Lucide (default), Heroicons (Tailwind), Phosphor (weights)
- Apply template -- see
references/icon-templates.md
- Verify consistency -- same style, same size within each section
Icon Style Rules
| Rule | Detail |
|---|
| No mixed styles | Use all outline OR all solid in a section |
| No emoji | Use proper icon components (tree-shakeable) |
| Use currentColor | Icons inherit text color via stroke="currentColor" |
| Semantic colors | Use text-primary, not text-blue-500 |
| Consistent sizing | Inline w-4 h-4, cards w-8 h-8, hero w-10 h-10 |
| Tree-shaking safe | Use explicit named imports and icon maps, never import * |
| Accessibility | Add aria-hidden="true" to decorative icons, aria-label to buttons |
Common Mistakes
| Mistake | Correct Pattern |
|---|
Importing all icons with import * as Icons breaking tree-shaking | Use explicit named imports and a static icon map |
| Mixing outline and solid icon styles within the same section | Pick one style per section and apply consistently |
| Using emoji instead of proper icon components | Always use tree-shakeable icon components from Lucide, Heroicons, or Phosphor |
Hardcoding color values like text-blue-500 on icons | Use semantic colors like text-primary so icons inherit theme changes |
| Choosing icons by visual appeal rather than semantic meaning | Map the concept first using the semantic mapping reference, then select the icon |
Missing aria-label on icon-only buttons | Add aria-label="Description" to buttons containing only icons |
| Using old Heroicons import paths without size prefix | Use @heroicons/react/24/outline with the size prefix |
Delegation
- Audit existing icon usage for consistency and tree-shaking issues: Use
Explore agent to scan imports and identify mixed styles or wildcard imports
- Migrate icons from Font Awesome or Material to modern libraries: Use
Task agent with the migration guide reference
- Plan icon system architecture for a design system: Use
Plan agent to select library, define sizing conventions, and establish semantic mappings
