What it does

Popular Web Designs is an agent skill from yc-software/qm. 54 real-world design systems (Stripe, Linear, Vercel, Notion, Apple…) as ready-to-paste HTML/CSS — exact colors, typography, components, and spacing for styling a page after a known brand.

Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 55 other files (for example `templates/airbnb.md`, `templates/airtable.md` and `templates/apple.md`).

It sits in Frontend & Design, covering Design systems and Typography. It works with Vercel, Notion and Stripe. The repository describes itself as: Multiplayer agent harness for work. The licence is MIT.

When your agent uses it

  • Tasks that involve Design systems
  • Tasks that involve Typography

Example prompts

  • “/popular-web-designs”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Pick a design from the catalog below
  2. Read it: skills({ action: "read", name: "popular-web-designs", path: "templates/.md" })
  3. Use the design tokens and component specs when generating HTML
  4. Build with files action write, then serve the result with the publish skill

What it can do on your machine

Read from SKILL.md and the folder at commit 747be10. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • fonts.googleapis.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Popular Web Designs loads about 2.9k tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 992 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

54 real-world design systems (Stripe, Linear, Vercel, Notion, Apple…) as ready-to-paste HTML/CSS — exact colors, typography, components, and spacing for styling a page after a known brand.

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.

Default look comes first

This skill is for when the user wants a page styled after a specific known brand. If they have not named one, use your deployment's house-style skill (a *-design skill in the Skills index, when installed) instead of picking from this catalog.

  • The house-style skill (*-design, when installed) — the org's default look as ready-to-apply tokens. Use it unless the user asks for a specific brand below.
  • taste-skill — use for the design process and taste (reading the brief, producing variants, verifying the result, avoiding AI-design slop). Pair it with this skill when the user wants a thoughtfully-designed page styled after a known brand: taste-skill drives the workflow, this skill supplies the visual vocabulary.

How to Use

  1. Pick a design from the catalog below
  2. Read it: skills({ action: "read", name: "popular-web-designs", path: "templates/<site>.md" })
  3. Use the design tokens and component specs when generating HTML
  4. Build with files action write, then serve the result with the publish skill

Each template includes an 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 files action write for HTML creation and local headless Chromium for verification

HTML Generation Pattern

html
<!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>

    <link href="https://fonts.googleapis.com/css2?family=..." rel="stylesheet" />
    <style>
      :root {
        --color-bg: #ffffff;
        --color-text: #171717;
        --color-accent: #533afd;
      }

      body {
        font-family: "Inter", system-ui, sans-serif;
        color: var(--color-text);
        background: var(--color-bg);
      }
    </style>
  </head>
  <body></body>
</html>

Write the file with files action write, verify the result locally (curl -fsS http://localhost:<port>, then chromium --headless --no-sandbox --disable-gpu --screenshot=/tmp/page.png http://localhost:<port> when a render check matters), and serve it with the publish skill to confirm visual accuracy and hand over a stable link.

Font Substitution Reference

Most sites use proprietary fonts unavailable via CDN. Each template maps to a Google Fonts substitute that preserves the design's character. Common mappings:

Proprietary FontCDN SubstituteCharacter
Geist / Geist SansGeist (on Google Fonts)Geometric, compressed tracking
Geist MonoGeist Mono (on Google Fonts)Clean monospace, ligatures
sohne-var (Stripe)Source Sans 3Light weight elegance
Berkeley MonoJetBrains MonoTechnical monospace
Airbnb Cereal VFDM SansRounded, friendly geometric
Circular (Spotify)DM SansGeometric, warm
figmaSansInterClean humanist
Pin Sans (Pinterest)DM SansFriendly, rounded
NVIDIA-EMEAInter (or Arial system)Industrial, clean
CoinbaseDisplay/SansDM SansGeometric, trustworthy
UberMoveDM SansBold, tight
HashiCorp SansInterEnterprise, neutral
waldenburgNormal (Sanity)Space GroteskGeometric, slightly condensed
IBM Plex Sans/MonoIBM Plex Sans/MonoAvailable on Google Fonts
Rubik (Sentry)RubikAvailable on Google Fonts

When a template's CDN font matches the original (Inter, IBM Plex, Rubik, Geist), no substitution loss occurs. When a substitute is used (DM Sans for Circular, Source Sans 3 for sohne-var), follow the template's weight, size, and letter-spacing values closely — those carry more visual identity than the specific font face.
