A set of rules and components for building Svelte 5 web interfaces with DryUI. Svelte is a framework for creating web interfaces, and the package covers controls, layout conventions, themes, and accessibility.

Use it to create or edit Svelte pages, routes, forms, dashboards, components, and design-to-code work with DryUI.

It gives implementation guidance for composing pages and responsive layouts while keeping the project’s linting and accessibility rules intact.

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	$0.00062	$0.01897
Opus 5	$0.00031	$0.00949
Sonnet 5	$0.00012	$0.00379
Haiku 4.5	$0.00006	$0.00190

Security

Grade C, and why

dryui-build scanned grade C with 1 finding 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 6d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

DryUI Build

Build real Svelte 5 UI with DryUI. This skill is only for UI implementation and polish. It does not install DryUI, scaffold projects, run live feedback, or resolve feedback submissions.

Lint First

DryUI lint rules are the contract. If lint, the compiler, or component metadata disagrees with a visual idea, restructure the markup or CSS instead of bypassing the rule.

Use @dryui/ui primitives when DryUI provides one. Do not recreate controls with raw HTML.
DryUI does not ship a layout component. Use plain markup with data-layout and data-layout-area.
Page and section layout lives in src/layout.css, scoped under [data-layout='<name>'].
All consumer display: grid and display: flex declarations live in src/layout.css or @container blocks inside it.
In src/layout.css, use only lint-safe display values such as grid or flex; never add display: block, contents, flow-root, or reset-style display values.
Route and component <style> blocks must not contain page-level display: grid, display: flex, layout breakpoints, inline style=, or Svelte style: directives.
Responsive layout is mobile-first and uses @container page (...); never @media for layout breakpoints.
src/layout.css is structural only: display, grid, flex, container, tokenized spacing, alignment, and block-size constraints. No color, background, border, shadow, opacity, transition, transform, font, text, position, z-index, width, height, or inline-size.
Visual CSS belongs in app/component CSS and uses real --dry-* tokens such as --dry-color-bg-base, --dry-color-text, and --dry-color-border, or app-owned custom properties.
In app/component CSS, constrain replaced media and text inside media-backed grids so intrinsic image size or long headings cannot enlarge grid tracks: use inline-size: 100%, max-inline-size: 100%, min-inline-size: 0, object-fit, and readable max-width/maxMeasure where needed.
Set body { font-family: var(--dry-font-sans); } in src/app.css so dialogs, popovers, and top-layer UI inherit the app font.

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.
