What is appCN CLAUDE.md?

Project instructions for appCN, an editable collection of React Native and Expo mobile interface components distributed through the shadcn command-line tool.

Use it to build, organize, preview, and document mobile components such as buttons, sheets, inputs, lists, tabs, chat bubbles, voice waveforms, and copilot overlays.

It explains how to keep component source code owned and editable while maintaining matching previews on the web and on real phones.

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	$0.02524	$0.02524
Opus 5.5	$0.01010	$0.01010
Sonnet 5.5	$0.00505	$0.00505

Security

Grade A, and why

appCN CLAUDE.md 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 2mo 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

appCN

A shadcn-philosophy component system for React Native / Expo: copy-paste ownership, editable source, NativeWind styling, motion-first premium defaults. Distributed through the shadcn CLI's custom-registry mechanism (npx shadcn add <url>), not as a black-box npm package.

Positioning

Base: a broad mobile component library (button, sheet, input, list, tabs, …).
Featured / hero: an AI-native mobile collection (packages/ui/src/ai/*) — streaming chat bubble, voice waveform, typing/thinking states, copilot overlay. This is the marketed wedge that differentiates appCN from the incumbent (React Native Reusables).
Differentiator: the previews experience — every component is viewable interactively in the browser, live on a real phone via QR (Expo), and as video.
- The interactive web preview is an iframe into the Expo web build (expo start --web, default :8081, route /c/<slug>), NOT react-native-web inside Next. Same code path as the phone, so web and device previews are guaranteed identical and we avoid NativeWind-in-Next config hell.
- The web app therefore has no React Native / NativeWind deps — it's plain Next.js + Tailwind v3.

Monorepo map

Turborepo + pnpm workspaces. The cross-bundler boundary (Metro for Expo vs Next for web) is handled inside the repo, not by splitting repos.

apps/
  web/        Next.js App Router — landing + docs + interactive previews + the registry JSON it serves
  showcase/   Expo Router app — renders every component; the target the docs QR codes deep-link into
packages/
  ui/         ★ SINGLE SOURCE OF TRUTH for all components (RN + NativeWind). Also exports the
              shared Tailwind/NativeWind preset + theme tokens consumed by BOTH apps.
  cli/        @app-cn/cli — the `appcn` binary: RN-aware shadcn wrapper (init + add). tsup-bundled.
  tsconfig/   shared TypeScript bases (@app-cn/tsconfig)

Golden rule: component source lives ONLY in packages/ui/src. The Expo app, the web previews, and the registry builder all read from there. Never fork a component into an app.

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.
