CodeAppsDevelopmentStandard: Skill for Claude Code

.github/skills/mobile-apps/SKILL.md

mobile-apps is a skill for Claude Code, Codex from geekfujiwara/CodeAppsDevelopmentStandard. It costs 59 tokens per session (2,799 once invoked), scanned A, original, MIT.

A guide for creating native mobile Power Apps Code Apps with Expo, React Native, and TypeScript. Native apps can use phone features such as the camera, barcode scanner, and location services.

In plain words
What is it for?
Use it to design and preview iOS or Android applications in the Power Apps Developer app, connect them to Power Platform, use native features, and prepare the supported Wrap and deployment flow.
Why use it?
It separates phone-specific applications from responsive browser apps and makes the Private Preview and production restrictions explicit.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

This is geekfujiwara/CodeAppsDevelopmentStandard's own configuration. It tells Claude Code and Codex how to work on CodeAppsDevelopmentStandard itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything CodeAppsDevelopmentStandard configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is python ../.github/skills/mobile-apps/scripts/validate_mobile_project.py ..

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00059 $0.02799
Opus 5.5 $0.00024 $0.01120

Security

Grade A, and why

mobile-apps 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 28d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/check_upstream.py, scripts/register_wrap_application.py, scripts/scaffold_mobile_app.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Power Apps Native Mobile Code Apps 開発スキル

Microsoft 公式 microsoft/power-platform-skills/plugins/mobile-apps を upstream として、 Expo + React Native + TypeScript の Native Mobile Code App を作成する。

[!CAUTION] Private Preview であり、本番利用は禁止。 スキル開始時、計画承認時、最終結果でこの制約を明示する。 ユーザーが Preview 利用を明示承認するまで scaffold、環境変更、Wrap 登録、push を開始しない。

Web Code App との境界

「モバイル対応」の依頼では、最初にどちらを求めているか確認する。

選択肢 ランタイム 選ぶ条件 スキル
レスポンシブ Web Code App React + Vite、ブラウザ／Power Apps player PC とモバイルで同じ Web UI、ネイティブ機能が不要 code-apps
Native Mobile Code App Expo + React Native、Power Apps Developer app／Wrap カメラ、バーコード、位置情報等の端末機能が必要 本スキル

Native 経路は Preview 承認に加え、対象 OS、必要な端末機能、オンライン要件、実機テスト端末を確認する。

ワークフロー

Step 0: Preview 利用を確認する

次を説明し、明示承認を得る。

  1. Private Preview で本番利用できない。
  2. iOS / Android のローカル native build や App Store / Google Play 配布は v0 の対応範囲外。
  3. 公式対応は Power Apps Developer app による実機 preview と、pa app push 後の Wrap 導線まで。
  4. Preview の破壊的変更に備え、upstream commit と依存セットを固定する。

承認がない場合は code-apps のレスポンシブ Web 案を提示して停止する。 承認後の scaffold は mobile-preview-approval.json を生成する。検証器はこの記録がなく、または productionAllowed: true のプロジェクトを拒否する。

Step 1: 要件とネイティブ機能を設計する

対象 OS、画面、データ、コネクタ、認証、端末機能、オンライン／オフライン要件を整理する。 端末機能は公式テンプレートの package.json に存在する module だけを候補にする。

  • Phase 1: Dataverse／connector、基本画面、camera／location／barcode、実機 preview、push
  • Phase 2: PDF、pen／signature、File／Image、sharing、生体認証
  • Phase 3: Offline Profile の authoring／assignment／drift check

オフライン runtime store／sync queue は upstream 対応を確認できるまで実装済みと扱わない。

Step 2: 公式テンプレートを生成する

Windows PowerShell 7 で、記録済み upstream commit から生成する。

python .github/skills/mobile-apps/scripts/scaffold_mobile_app.py `
  --target ./my-mobile-app `
  --preview-approved `
  --install
Set-Location ./my-mobile-app

依存は upstream-template.json の互換性セットを使う。 Expo、React Native、Tamagui、native host、Power Apps SDK を個別に latest へ上げない。

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.
