Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

popular-web-designs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

98% identical to popular-web-designs — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.

54 real-world design systems ready for use when generating HTML/CSS. Each template captures a site's complete visual language: color palette, typography hierarchy, component styles, spacing system, shadows, responsive behavior, and practical agent prompts with exact CSS values.

  • claude-design — use for the design process and taste (scoping a brief, producing variants, verifying a local HTML artifact, avoiding AI-design slop). Pair it with this skill when the user wants a thoughtfully-designed page styled after a known brand: claude-design drives the workflow, this skill supplies the visual vocabulary.
  • design-md — use when the deliverable is a formal DESIGN.md token spec file, not a rendered artifact.

How to Use

  1. Pick a design from the catalog below
  2. Load it: skill_view(name="popular-web-designs", file_path="templates/<site>.md")
  3. Use the design tokens and component specs when generating HTML
  4. Pair with the generative-widgets skill to serve the result via cloudflared tunnel

Each template includes a the agent Implementation Notes block at the top with:

  • CDN font substitute and Google Fonts <link> tag (ready to paste)
  • CSS font-family stacks for primary and monospace
  • Reminders to use write_file for HTML creation and browser_vision for verification

HTML Generation Pattern

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Page Title</title>
  <!-- Paste the Google Fonts <link> from the template's the agent notes -->
  <link href="https://fonts.googleapis.com/css2?family=..." rel="stylesheet">
  <style>
    /* Apply the template's color palette as CSS custom properties */
    :root {
      --color-bg: #ffffff;
      --color-text: #171717;
      --color-accent: #533afd;
      /* ... more from template Section 2 */
    }
    /* Apply typography from template Section 3 */
    body {
      font-family: 'Inter', system-ui, sans-serif;
      color: var(--color-text);
      background: var(--color-bg);
    }
    /* Apply component styles from template Section 4 */
    /* Apply layout from template Section 5 */
    /* Apply shadows from template Section 6 */
  </style>
</head>

  <!-- Build using component specs from the template -->

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
