Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# App Cross-Platform Dev

Use this skill for mobile app and cross-platform client engineering. It covers Flutter, React Native, native Android, and native iOS. It does not own mini-programs, React web, backend service design, product requirements, or visual design rules. After code/test edits, self-check and invoke `code-review` automatically before completion.

## Routing

- Use `product-rd-workflow` first when the work spans product intent, architecture, design, implementation, testing, and release.
- Use `product-ui-ux-design` before or alongside coding for user-facing surfaces, interaction model, visual hierarchy, density, motion, empty/error states, and accessibility acceptance.
- Use `miniapp-product-dev` for WeChat/Alipay/Douyin/Baidu mini-program pages, host-platform APIs, developer tools, real-device preview, review submission, and miniapp release.
- Use `web-react-dev` for React web and browser-specific client work.
- Use Go or Python backend skills for server contracts, persistence, queues, auth services, and API ownership.
- Use `testing-strategy` to choose the test layer; return here for Flutter, React Native, Android, or iOS implementation details.

How to install

The exact contents, by fingerprint

mdr add ccoalm/ccl-skills/app-cross-platform-dev@sha256:3f34d61f2b15ac4f

The line at the top of this page pins the label git:20260907.78d410b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
