Mobile Tauri

Mobile/Desktop Developer - Tauri v2 (OPCIONAL)

Skill OPCIONAL. Usa Tauri para empacotar o frontend web como app nativo para Android, Windows, macOS e Linux.

Governanca Global

Esta skill segue GLOBAL.md, policies/execution.md, policies/handoffs.md, policies/quality-gates.md, policies/token-efficiency.md, policies/stack-flexibility.md, policies/tool-safety.md e policies/evals.md.

Para setup detalhado, permissoes e builds nativos, consultar docs/skill-guides/mobile-tauri.md apenas quando necessario.

Quando Usar

• adaptar projeto web para app desktop ou mobile via Tauri
• configurar build nativo, permissao e integracao com APIs nativas

Quando Nao Usar

• quando o projeto nao precisa de distribuicao nativa
• para deploy web padrao sem camada nativa

Entradas Esperadas

• frontend web funcional
• restricoes de plataforma e distribuicao
• requisitos de permissao, storage e notificacao

Saidas Esperadas

• estrategia de empacotamento nativo
• configuracao de permissao e build coerentes
• handoff claro para QA/Deploy

Responsabilidades

1. Configurar projeto Tauri no repositório existente
2. Adaptar frontend para mobile/desktop (navegação, safe areas, responsividade)
3. Gerar builds nativos (APK, .exe/.msi, .dmg, .deb/.AppImage)
4. Configurar permissões nativas com princípio de menor privilégio
5. Implementar features nativas (notificações, file system, shell)
6. Otimizar performance para dispositivos mobile de baixo custo

Adaptacoes Mobile

Deteccao de Plataforma

import { platform } from '@tauri-apps/plugin-os';

function isTauri(): boolean {
  return typeof window !== 'undefined' && '__TAURI__' in window;
}

async function getPlatform(): Promise {
  if (!isTauri()) return 'web';
  const p = await platform();
  return p as 'android' | 'ios' | 'windows' | 'macos' | 'linux';
}

Hook de Navegacao Mobile

import { useState, useEffect } from 'react';

interface MobileNavState {
  showBackButton: boolean;
  showBottomNav: boolean;
  showSidebar: boolean;
  safeAreaInsets: {
    top: number;
    bottom: number;
    left: number;
    right: number;
  };
}

function useMobileNavigation(): MobileNavState {
  const [state, setState] = useState({
    showBackButton: false,
    showBottomNav: false,
    showSidebar: true,
    safeAreaInsets: { top: 0, bottom: 0, left: 0, right: 0 },
  });

  useEffect(() => {
    async function detect() {
      const p = await getPlatform();
      const isMobile = p === 'android' || p === 'ios';

      setState({
        showBackButton: isMobile,
        showBottomNav: isMobile,
        showSidebar: !isMobile,
        safeAreaInsets: isMobile
          ? { top: 44, bottom: 34, left: 0, right: 0 }
          : { top: 0, bottom: 0, left: 0, right: 0 },
      });
    }

    detect();
  }, []);

  return state;
}

CSS Safe Areas

  --safe-area-top: env(safe-area-inset-top, 0px);
  --safe-area-bottom: env(safe-area-inset-bottom, 0px);
  --safe-area-left: env(safe-area-inset-left, 0px);
  --safe-area-right: env(safe-area-inset-right, 0px);

  padding-top: var(--safe-area-top);
  padding-bottom: var(--safe-area-bottom);
  padding-left: var(--safe-area-left);
  padding-right: var(--safe-area-right);
  min-height: 100dvh;

.bottom-nav {
  position: fixed;
  bottom: 0;
  left: 0;
  right: 0;
  padding-bottom: var(--safe-area-bottom);
  background: white;

Deep links configurados (se aplicavel)
Auto-update configurado para desktop (se aplicavel)
Testado em dispositivo real (Android + desktop)

Evidencia de Conclusao

• build e permissao planejados com menor privilegio
• impacto de mobile/desktop documentado
• riscos de distribuicao e QA destacados

Handoff

Recebe do Frontend

1. App web funcional com build de producao
2. Assets (icones, splash) em alta resolucao
3. Lista de features que precisam de acesso nativo
4. Variaveis de ambiente documentadas

Entrega para QA

1. APK de debug e release assinado
2. Executaveis desktop (Windows, macOS, Linux)
3. Lista de permissoes nativas utilizadas e justificativa
4. Instrucoes de instalacao por plataforma
5. Matriz de features nativas vs web (o que funciona em cada)

Regra de Codigo

Comentarios no codigo so fazem sentido quando explicam contexto nao obvio, restricoes externas ou workarounds temporarios. Nomes de funcoes, variaveis e tipos devem ser autoexplicativos.
