favicon-gen
Generate custom favicons from logos, text, or brand colours. Produces favicon.svg, favicon.ico, apple-touch-icon.png, icon-192/512.png, and web manifest. Use whenever the user wants a favicon, mentions replacing a CMS default favicon, converting a logo into a favicon, creating branded initials icons, or troubleshooting favicon not displaying / iOS black square / missing manifest.
Resumen
Favicon Generator
Generate a complete favicon package from a logo, initials, or brand colours. Produces all required formats and HTML integration code.
Workflow
Step 1: Choose Your Approach
Have a logo with an icon element?
YES -> Extract icon from logo
NO -> Have text/initials?
YES -> Create monogram favicon
NO -> Use branded shapeStep 2: Create Source SVG
Extracted icon — copy icon paths from logo, centre in 32x32 viewBox, simplify for small sizes.
Monogram — use a template from assets/:
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32">
<circle cx="16" cy="16" r="16" fill="#0066cc"/>
<text x="16" y="21" font-size="16" font-weight="bold"
text-anchor="middle" fill="#ffffff" font-family="sans-serif">AC</text>
</svg>Branded shape — circle (universal), rounded square (modern), shield (security), hexagon (tech).
SVG templates available in assets/ directory.
Step 3: Generate All Formats
Requires ImageMagick (convert command). Install if needed: brew install imagemagick (macOS) or apt install imagemagick (Linux).
# ICO (16x16 + 32x32)
convert favicon.svg -define icon:auto-resize=16,32 favicon.ico
# Apple Touch Icon (180x180, SOLID background — transparent = black on iOS)
convert favicon.svg -resize 180x180 -background "#0066cc" -alpha remove apple-touch-icon.png
# Android/PWA icons
convert favicon.svg -resize 192x192 icon-192.png
convert favicon.svg -resize 512x512 icon-512.pngNo ImageMagick? Use https://favicon.io to convert from the SVG instead.
Step 4: Create Web Manifest
Copy and customise assets/manifest.webmanifest:
{
"name": "Your Business Name",
"short_name": "Business",
"icons": [
{ "src": "/icon-192.png", "sizes": "192x192", "type": "image/png" },
{ "src": "/icon-512.png", "sizes": "512x512", "type": "image/png" }
],
"theme_color": "#0066cc",
"background_color": "#ffffff",
"display": "standalone"
}Step 5: Add HTML Tags
<link rel="icon" type="image/svg+xml" href="/favicon.svg">
<link rel="icon" type="image/x-icon" href="/favicon.ico">
<link rel="apple-touch-icon" sizes="180x180" href="/apple-touch-icon.png">
<link rel="manifest" href="/site.webmanifest">
<meta name="theme-color" content="#0066cc">Place all files in site root (/public/ in Vite/React).
Critical Rules
- Always generate ALL formats — SVG, ICO, apple-touch-icon, 192, 512, manifest
- iOS icons MUST have solid backgrounds — transparent = black square
- Always use bold font weight for monogram text (regular disappears at 16x16)
- Test at 16x16 — if it's not legible, simplify
- Never launch with CMS defaults (WordPress "W", etc.)

npx skills add jezweb/claude-skills --skill favicon-genMás de jezweb
- shadcn-uijezwebInstall and configure shadcn/ui components for React projects. Guides component selection, installation order, dependency management, customisation with semantic tokens, and common UI recipes (forms, data tables, navigation, modals). Use after tailwind-theme-builder has set up the theme infrastructure, when adding components, building forms, creating data tables, or setting up navigation.3,500 instalaciones en skills.sh0
- tailwind-theme-builderjezwebSet up Tailwind v4 + shadcn/ui themed UI with dark mode. Install deps, configure CSS variables via @theme inline, wire dark mode toggle, verify. Use whenever the user mentions Tailwind v4, setting up Tailwind theming, shadcn/ui colours, dark mode, or troubleshooting colours not working, tw-animate-css errors, @theme inline conflicts, @apply breaking after upgrade, or v3 → v4 migration issues.3,200 instalaciones en skills.sh0
- color-palettejezwebGenerate complete, accessible colour palettes from a single brand hex. Produces 11-shade scale (50-950), semantic tokens, dark mode variants, Tailwind v4 CSS output, WCAG contrast checks. Use whenever the user supplies a brand hex and asks for a palette, mentions setting up a design system, wants Tailwind theme colours from a brand colour, or asks to check colour accessibility / contrast.3,100 instalaciones en skills.sh0
- wordpress-elementorjezwebEdit Elementor pages and manage templates on WordPress sites via browser automation (for visual / structural changes) or WP-CLI (for safe text replacements). Use whenever the user wants to edit an Elementor page, update text in Elementor widgets, apply or manage Elementor templates, or make content changes to pages built with the Elementor page builder.2,800 instalaciones en skills.sh0
- ux-auditjezwebWalk through a live web app AS a real user to find usability + behavioural bugs that static reviews miss. REQUIRES proof of interaction (typing, clicking, sending, observing) before any verdict — a sweep that didn't interact terminates with verdict 'Incomplete'. Walks threads, exercises every element, runs the multi-pane stress matrix, visual polish sweep, component perfection checklist, automated a11y (axe-core), pragmatic performance budget (LCP/CLS/INP), scenario battery (11 scenarios), and stress recipes including the real-flavour data battery. Hard gates: console errors/warnings = 0, network 5xx = 0, layout collapse = 0, axe Critical/Serious = 0, perf budget green. Audit-the-audit meta-check rejects rushed reports. Each finding has reproduction steps, evidence path, and suspected code location. Trigger with 'ux audit', 'walkthrough', 'qa sweep', 'audit the app', 'dogfood this', 'check all pages', 'find what's broken', 'stress the UI'.2,700 instalaciones en skills.sh0
