Validate Mobile Skill

CLAUDE: When this skill is invoked with /validate-mobile, run these commands in sequence:

cd frontend-mobile && bun run typecheck && bun run lint && bun test

Purpose

Validates the mobile app codebase (Expo + React Native + NativeWind) for type safety, lint compliance, and test correctness.

Usage

/validate-mobile

What It Validates

Tier 0: TypeScript (fastest feedback)

cd frontend-mobile && bun run typecheck
  • Catches type errors before runtime
  • Validates all .ts and .tsx files
  • Uses TypeScript strict mode

Tier 1: ESLint

cd frontend-mobile && bun run lint
  • React hooks rules
  • React Native specific rules
  • TypeScript ESLint integration

Tier 2: Unit Tests

cd frontend-mobile && bun test
  • Runs Jest with jest-expo preset
  • Tests components, hooks, and utilities
  • Uses Testing Library for React Native

Full Validation Command

cd frontend-mobile && bun run typecheck && bun run lint && bun test

Additional Commands

E2E Tests (requires iOS Simulator)

cd frontend-mobile && bun run e2e:build && bun run e2e:test

Integration Tests

cd frontend-mobile && bun run e2e:integration

Coverage Report

cd frontend-mobile && bun run test:coverage

Watch Mode

cd frontend-mobile && bun run test:watch

Port Configuration

CRITICAL: Mobile dev server uses port 8082 (port 8081 is reserved for Pierre MCP Server)

cd frontend-mobile && bun start  # Uses port 8082

Success Criteria

  • All TypeScript files compile without errors
  • Zero ESLint violations
  • All unit tests pass (135+ tests)
  • No type regressions
