Performance

• Duration: 4 min
• Started: 2026-01-31T04:04:21Z
• Completed: 2026-01-31T04:08:41Z
• Tasks: 3
• Files created: 11

Accomplishments

• Created GoogleSignInButton component with Google icon SVG and signInWithOAuth
• Built complete login and register pages with Google button prominently above email form
• Added "oppure" divider to separate social login from email form
• Created comprehensive Google OAuth setup documentation
• All UI text in Italian per project requirement

Task Commits

Each task was committed atomically:

1. Task 1: Create Google Sign-In button component - 1d454d2 (feat)
2. Task 2: Add Google button to login and register pages - dcbd7e8 (feat)
3. Task 3: Document Google OAuth setup process - bd0df40 (docs)

Files Created

• src/lib/utils.ts - cn() utility for class name merging
• src/components/ui/button.tsx - Button component with variants
• src/components/ui/card.tsx - Card component with Header, Title, Content
• src/components/ui/input.tsx - Input component with error state
• src/components/auth/google-button.tsx - Google OAuth button
• src/components/auth/login-form.tsx - Email/password login form
• src/components/auth/register-form.tsx - Registration form with validation
• src/app/(auth)/layout.tsx - Centered auth layout
• src/app/(auth)/login/page.tsx - Login page with Google + email
• src/app/(auth)/register/page.tsx - Register page with Google + email
• docs/GOOGLE_OAUTH_SETUP.md - Setup guide for Google Cloud + Supabase

Decisions Made

1. Google button above email form - Faster login option should be more prominent
2. Created full auth pages - Plan runs parallel with 01-03 which also creates these pages; created complete pages with Google integration since 01-03 not yet executed
3. Client-side forms - Used client-side state management for forms since OAuth requires client-side redirect handling; Server Actions can be added later if needed

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Created UI components and forms not in plan scope

• Found during: Task 2 (Add Google button to pages)
• Issue: Login/register pages didn't exist (01-03 not yet executed), and plan specifies "If they don't exist, create them with the Google button included"
• Fix: Created full auth pages including layout, forms, and UI components
• Files created: src/components/ui/input.tsx, src/components/auth/login-form.tsx, src/components/auth/register-form.tsx, src/app/(auth)/layout.tsx
• Verification: Build passes, pages render correctly
• Committed in: dcbd7e8

---

Total deviations: 1 auto-fixed (blocking - parallel plan dependency) Impact on plan: Extended scope to create complete auth UI since parallel plan 01-03 not yet executed. When 01-03 runs, it may need to skip or modify already-created files.

Issues Encountered

None - plan executed smoothly.

User Setup Required

External services require manual configuration. See docs/GOOGLE_OAUTH_SETUP.md for:

• Google Cloud Console OAuth client ID creation
• Supabase Dashboard Google provider configuration
• Testing steps and troubleshooting guide

Next Phase Readiness

• Google OAuth button ready and functional
• Login and register pages complete
• Auth callback at /auth/callback expected to exist (from 01-01)
• Middleware for session refresh needed (01-05)
• Protected routes needed for /dashboard redirect (01-06)
