What is popular-web-designs?

A collection of 54 design references based on real websites, including systems inspired by Stripe, Linear, Vercel, Notion, and Airbnb. Each reference describes colors, fonts, spacing, layouts, components, and responsive behavior for building HTML and CSS.

Use it when generating HTML/CSS pages, choosing a visual style, defining design tokens, or recreating the look and behavior of a selected website.

It gives a developer concrete visual rules to follow instead of starting a web design from vague style descriptions. The references help keep a page’s appearance consistent across its parts and screen sizes.

popular-web-designs — Skill for Claude Code and Codex by moltis-org

About the project

Moltis is a persistent personal agent server written in Rust that runs on hardware controlled by its user. It provides an AI agent with sandboxed command execution, model-provider connections, memory, voice, scheduling, messaging integrations, browser automation, and MCP tools. Its catalogue add-ons extend the agent’s workflows and available tools.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00066	$0.02295
Opus 5	$0.00033	$0.01148
Sonnet 5	$0.00013	$0.00459
Haiku 4.5	$0.00007	$0.00230

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 11d 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

Popular Web Designs

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.

How to Use

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

Each template includes a 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 implementation 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>
<body>
  <!-- Build using component specs from the template -->
</body>
</html>

Write the file with write_file, serve with the generative-widgets workflow (cloudflared tunnel), and verify the result with browser_vision to confirm visual accuracy.

What this file has done since we first saw it

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.
