What is responsive-ui?

A set of rules for building interfaces that work across different screen sizes and devices. It covers breakpoints, web and React Native patterns, safe areas, overflow, and touch-target sizing.

It is for planning responsive web or React Native layouts, choosing breakpoints, handling device safe areas, controlling overflow, and sizing touch controls.

It helps avoid layouts that break on phones, tablets, or other screen sizes, and reduces problems caused by cramped or unreachable controls.

Install

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.

Clone the repo

git clone --depth 1 https://github.com/jaycewalzer1/SilverKey-Inc.

Made for: Cursor.

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	$0.00000	$0.00564
Opus 5.5	$0.00000	$0.00226
Sonnet 5.5	$0.00000	$0.00113
Haiku 4.5	$0.00000	$0.00056

Security

Grade A, and why

responsive-ui 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.

What it actually says

Responsive UI (SilverKey)

Canonical reference: documentation/guides/responsive-ui-standards.md — read it for WEB-1–WEB-8, RN-1–RN-10, BOTH-1–BOTH-5, SilverKey route notes, and the seven-area path map.

Must follow (summary)

Mobile-first (web): Base layout for small screens; add sm: / md: / lg: only to enhance. Do not use max-width hacks to bolt mobile onto desktop-first layouts.
No accidental desktop changes: Preserve desktop appearance unless fixing a real bug or applying a necessary global rule. Prefer minimal diffs.
Overflow: Use min-w-0 on flex children with long text; wrap tables in overflow-x-auto. Do not add overflow-x-hidden to ancestors of position: sticky without checking sticky behavior.
Touch targets: ≥44×44px (web: min size / padding; RN: minHeight/minWidth or hitSlop).
Forms (web): Inputs use at least text-base on touch devices to reduce iOS zoom-on-focus.
React Native: SafeAreaView from react-native-safe-area-context on root screens; keyboard + ScrollView patterns per doc; bounded images (width: '100%' + aspectRatio where appropriate).
Design system: Keep using standardized Button, Title, BodyText, etc. from Client/packages/ui/ (or @/components/ui / @ui aliases) — responsive work adjusts layout and primitives, not one-off raw <button>/heading styles.

SilverKey specifics

Public landing lives under packages/features/homeauth/.../landing/ (web HomeFeature.web.tsx).
Post-login (web): default is /dashboard, not a separate home route.
Mobile auth welcome: HomeScreenNative is pre-login; first tab after auth is Dashboard.

After edits

Run pnpm lint and pnpm typecheck in Client/ when touching responsive code (see documentation/reference/linting.md).

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.
