English

Orchestration & Integration

Connects and orchestrates with domain skills like brainstorming, zero-to-prod-orchestrator, saas-multi-tenant, saas-billing, session-memory-manager, prd-architect, and production-ready-hardener.

• MANDATORY: Execute senior-frontend FIRST for all frontend HTML/CSS/JS features to ensure compliance with modern standards.

Description

The SaaS Architect is the master lifecycle orchestrator for building commercial SaaS platforms. It operates in two specialized modes:

• Mode A (Greenfield MVP 0-to-1): Validating ideas, rapid stack selection, multi-entry points architecture, authentication, billing setup, and launch checklist.
• Mode B (App Modernization 1-to-N): Systematically converting existing single-tenant or internal applications into enterprise-grade multi-tenant SaaS platforms using a 9-phase transformation pipeline.

Trigger Conditions

• Planning or launching a brand-new SaaS product from scratch.
• Modernizing or converting an existing web app into a commercial SaaS.
• Setting up multi-tenancy, workspace isolation, team management, or feature gating.
• Conducting a technical audit of an existing SaaS architecture.

---

Mode A: Greenfield SaaS MVP (0 to 1)

1. Idea Validation & Scoping

• Define the exact customer problem in one sentence.
• Verify 3+ pre-commitments or letters of intent before deep coding.
• Keep MVP scope tight (target 4-6 weeks to launch).

2. Modern SaaS Stack Blueprint (2026)

• Frontend & App: Next.js 15 App Router + React 19 + TypeScript.
• Styling & UI: Tailwind CSS v4 + Base UI / shadcn/ui primitives.
• Data Layer: PostgreSQL (Neon Serverless / Supabase) via Drizzle ORM or Prisma 6.
• Auth: Clerk, Auth.js v5, or Supabase Auth with OAuth2 PKCE.
• Billing: Stripe / Midtrans / DOKU via webhook-driven synchronization.
• Email & Jobs: Resend + React Email; BullMQ / Trigger.dev v3 for background jobs.
• Deployment: Vercel / Cloudflare Edge with zero-config CI/CD.

3. Architecture & Entry Points Isolation

Apply the multiple-entry-points architecture (guided by cloud-hosting-expert) to segregate responsibilities:

• Public Entry (app.example.com or example.com): Marketing landing, pricing, documentation, and blog.
• Tenant Dashboard (app.example.com/dashboard or [tenant].example.com): Authenticated customer workspace.
• Super Admin Subdomain (admin.example.com): Dedicated subdomain strictly isolated from customer tenant routes for global metrics, tenant provisioning, user moderation, and feature override controls.

4. Pre-Launch Quality Gate

• Authentication and session validation (Edge JWT + Redis caching).
• Webhook signature validation active for all billing events.
• Error tracking configured (Sentry) and rate limiting on API routes.
• ToS, Privacy Policy, and 2-3 pricing tiers with trial workflows.

Mode B: SaaS Transformation & Modernization (1 to N)

For existing codebases, execute the structured 9-phase transformation pipeline:

┌──────────────────────────────────────────────────────────────────┐
│                   SAAS TRANSFORMATION PIPELINE                   │
│  Phase 1: Discovery & Architecture Audit (Scanner script)        │
│  Phase 2: Multi-Tenancy & Data Isolation (saas-multi-tenant)    │
│  Phase 3: Identity & RBAC Management (authentication-identity)  │
│  Phase 4: Billing, Subscriptions & Webhooks (saas-billing)      │
│  Phase 5: Workspace & Team Collaboration (Invites, Roles)        │
│  Phase 6: Frontend App Shell & Multi-Entry Points               │
│  Phase 7: Feature Gating, Limits & Metering                     │
│  Phase 8: Production Hardening, Testing & Security Audit        │
│  Phase 9: Deployment, Multi-Tenant Monitoring & Launch          │
└──────────────────────────────────────────────────────────────────┘

Transformation Scanner

Run python scripts/saas_transformation_scanner.py to inspect the legacy codebase. It scores readiness across:

1. Multi-Tenancy Readiness (Foreign keys, tenant isolation)
2. Auth & RBAC Maturity
3. Billing & Subscription hooks
4. Feature Gating presence

Core Modernization Principles

• Data Isolation: Refer to saas-multi-tenant for Shared Schema RLS or Schema-per-tenant patterns. Do not write raw duplicate schemas.
• Subscription State Machine: Refer to saas-billing for webhook handling, invoice synchronization, and dunning cycles.
• Feature Gating: Implement hierarchical checks (System Flag -> Plan Tier -> Tenant Addon -> User Role) as detailed in references/feature_gating_patterns.md.

🎨 Automatic Visual Assets Generation Mandate (CRITICAL)

When initializing or scaffolding any new SaaS application:

1. Automatically invoke generate_image to create a production-quality application logo matching the brand identity.
2. Use this asset immediately as the navbar logo, browser favicon (favicon.ico), and Open Graph social banner (og:image). Never use placeholder icons.

📄 Standard Pages Mandate

Every SaaS application must scaffold complete, functional implementations for:

• Landing Page (Hero, Features, Social Proof, Pricing, FAQ)
• Authentication (Sign In, Sign Up, Password Reset, Magic Link)
• Onboarding Wizard (<5 minutes to first value)
• Settings (Profile, Workspace, Team Members, Billing / Plans, API Keys)
• Super Admin Panel on dedicated subdomain (admin.example.com)

Integrasi Orkestrasi

Terhubung dan mengorkestrasi skill domain seperti brainstorming, zero-to-prod-orchestrator, saas-multi-tenant, saas-billing, session-memory-manager, prd-architect, dan production-ready-hardener.

• WAJIB: Jalankan senior-frontend PERTAMA KALI untuk semua pengerjaan frontend web.

Deskripsi

SaaS Architect adalah orkestrator siklus hidup utama untuk membangun platform SaaS komersial. Beroperasi dalam dua mode:

• Mode A (Greenfield MVP 0 ke 1): Validasi ide, pemilihan tech stack kilat, arsitektur multi-entry points, autentikasi, billing, dan checklist peluncuran.
• Mode B (Modernisasi Aplikasi 1 ke N): Mentransformasi aplikasi single-tenant atau internal yang sudah ada menjadi SaaS multi-tenant enterprise menggunakan pipeline 9 fase terstruktur.

Kondisi Pemicu

• Membangun produk SaaS baru dari awal.
• Memodernisasi atau mengubah aplikasi web biasa menjadi SaaS komersial.
• Mengonfigurasi multi-tenancy, isolasi ruang kerja (workspace), manajemen tim, atau feature gating.
• Melakukan audit arsitektur teknis SaaS.

---

Mode A: SaaS MVP dari Nol (0 ke 1)

1. Validasi Ide: Rumuskan masalah dalam satu kalimat, validasi dengan 3+ komitmen bayar sebelum mulai coding.
2. Tech Stack Modern (2026): Next.js 15 App Router, Tailwind CSS v4, PostgreSQL (Neon/Supabase) via Drizzle/Prisma, Clerk/Auth.js, Stripe/Midtrans/DOKU, Resend, Vercel.
3. Isolasi Entry Point: Pisahkan landing page publik, dashboard penyewa (tenant), dan Dashboard Super Admin pada subdomain terpisah (admin.example.com).
4. Gerbang Kualitas Pra-Rilis: Sesi login teroptimasi (JWT + Redis), webhook billing tervalidasi, Sentry aktif, rate limiting, halaman harga 2-3 tier.

---

Mode B: Transformasi & Modernisasi SaaS (1 ke N)

Gunakan pipeline 9 fase terstruktur:

1. Audit arsitektur & jalankan python scripts/saas_transformation_scanner.py.
2. Fondasi multi-tenancy (merujuk ke saas-multi-tenant).
3. Autentikasi terpusat & RBAC (merujuk ke authentication-identity-expert).
4. Mesin billing & siklus langganan (merujuk ke saas-billing).
5. Manajemen tim & undangan workspace.
6. Shell frontend & pemisahan entry point.
7. Feature gating berjenjang (references/feature_gating_patterns.md).
8. Pengujian E2E & hardening keamanan.
9. Rilis & pemantauan multi-tenant.

🎨 Mandat Pembuatan Aset Visual Otomatis (KRITIS)

Gunakan tool generate_image secara otomatis untuk membuat logo aplikasi kustom saat inisialisasi aplikasi. Pasang logo tersebut sebagai logo navbar, favicon (favicon.ico), dan gambar Open Graph (og:image). Dilarang memakai placeholder.
