An experimental skill for turning a design image into a responsive page layout made of colored blocks. It builds only the page structure, such as navigation, main content, sidebars, and panels.

In plain words
What is it for?
Use it to create a full-page or section layout skeleton in Svelte, with different arrangements for mobile, tablet, and desktop.
Why use it?
It lets you test page proportions and responsive arrangement before spending time on detailed interface elements.

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

dryui-build 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

DryUI Layout Blocks: Shell Area Strict

Build only a colored block layout skeleton. Do not recreate detailed UI.

Only edit:

  • src/routes/+page.svelte
  • src/layout.css

Do not import anything. Do not use DryUI components, Lucide, icons, SVGs, images, charts, tables, forms, buttons, inputs, avatars, realistic widgets, or generated data.

1. Classify The Task

  • Full page: build a page shell with topbar/navigation, primary, and optional secondary, utility, rail, summary, actions.
  • Page section: build a section shell with primary and optional adjacent regions.

For full-page design-image references, treat the whole image as the page shell.

2. Blueprint Before Coding

Write the region plan mentally before editing:

  • Mobile: one-column top-to-bottom order.
  • Tablet: first useful two-pane/grouped composition.
  • Desktop: persistent rail/sidebar, right panels, attached panes, dominant work surface.

Decide:

  • Which region is primary.
  • Whether spacing is contiguous, guttered, or mixed.
  • Which regions are secondary or utility, so they do not become larger than primary.
  • Which visible bands are shell regions versus nested primitives.

3. Use Recipes Only For Proportions

Do not change required area names for a recipe.

  • Dashboard: summary strip, primary chart/workspace, insights/activity.
  • Board/Kanban: board is primary; task detail is secondary; activity is utility; desktop rail if present.
  • CRM: table/pipeline is primary; account/detail is secondary; forecast/activity are utility.
  • Settings/Admin: settings/profile/form stack is primary; help/status/activity are secondary/utility; compact actions; desktop rail if present.
  • Knowledge/Document Reader: reader is primary; collections/list are navigation/secondary; AI summary is secondary/utility; reader must be largest at desktop.

4. Markup Contract

For a full page, use this direct-child shape:

<main data-layout="<name>-shell">
	<div data-layout-area="page">
		<header data-layout-area="topbar">Topbar</header>
		<nav data-layout-area="navigation">Navigation</nav>
		<section data-layout-area="primary">Primary workspace</section>
		<aside data-layout-area="secondary">Secondary panel</aside>
	</div>
</main>

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.
