UI Templates — Human-Designed Template Library

380 pre-built HTML/CSS/JS templates from 9 professional template libraries. All templates are human-designed with real design quality — NOT AI-generated. The agent MUST use an existing template as the starting point. Never write HTML/CSS/JS from scratch.

1. How to Find Templates

Step 1 — Determine the Category

Match the user's request to one or more categories from §4 Category Reference. Be precise — match the user's actual stated need, not a generalized assumption.

• "I want a restaurant website" → restaurant
• "Build me a portfolio" → portfolio
• "I need a blog" → blog
• "Make a landing page for my app" → app or landing
• Unclear or general request → read 2-3 candidate category catalogs and compare

Step 2 — Read the Category Catalog

Each category has a JSON catalog file: catalogs/{category}.json (relative to this skill directory).

read_file("skills/ui-templates/catalogs/{category}.json")

If no specific category matches, use catalogs/multipurpose.json. For broad requests, read multiple catalogs (e.g., both personal and portfolio).

Step 3 — Match Templates Using Catalog Metadata

Each catalog entry contains rich metadata for intelligent selection:

Matching priority:

1. matchSignals keyword overlap with user request
2. features and sections matching user's functional needs
3. colorScheme + visualStyle matching user's aesthetic preference
4. source quality tier (prefer higher tiers)

Step 4 — Download and Use the Template

Templates are hosted on GCS. Each catalog entry has a downloadUrl field pointing to a .zip file.

# Download and extract the template
curl -sL "{downloadUrl}" -o /tmp/template.zip
mkdir -p output/website
unzip -o /tmp/template.zip -d output/website/
rm /tmp/template.zip

After extraction, use the indexPath field from the catalog entry to locate the index.html within the extracted directory.

2. Customization Guide

When customizing a template, focus on content replacement while preserving the human-designed structure:

1. Page title & headings — Update <title> and main headings
2. Navigation — Adjust nav links to match actual sections
3. Body text — Replace lorem ipsum with real content
4. Images — Keep template originals unless user provides their own
5. Colors — Use colorPalette to understand which CSS properties to modify for brand colors
6. Fonts — Keep the template's fonts (already well-chosen by human designers)
7. Sections — Add/remove/reorder sections to match user needs
8. Responsive — Most templates are already responsive. Check breakpoints field.

6. Important Notes

• All 380 templates are usable — every template has an index.html file. Use indexPath to find it under ui-templates/.
• Category catalogs — read catalogs/{category}.json for enriched metadata.
• Keep the human design — these templates look good because humans designed them. Don't over-modify the CSS structure.
• Use colorPalette for customization — when the user has brand colors, use colorPalette to understand which CSS colors to replace.
• Responsive — most templates are already responsive. Check breakpoints for responsive behavior.
