Next.js Auth View Discovery + Clean Platform Scaffold

Quick start

1. Identify router type and entry points.
2. Inventory routes, auth boundaries, and roles.
3. Run a route naming audit (librarian pass).
4. Confirm the view list and new names with the user.
5. Derive the platform name and route segment from existing copy.
6. Scaffold app/<platform-segment> public/app layouts.
7. Add the landing header dropdown link.
8. Smoke-test public and auth routes.

Scope

Does:

• Inventory public vs authenticated routes and role gates.
• Confirm view naming and scope before scaffold.
• Create a clean App Router subtree for the new platform.
• Keep legacy routes intact and isolated.

Does not:

• Migrate every legacy screen.
• Change auth logic or delete old code.

Required inputs

Derive before scaffolding (do not ask the user):

• platformName
• platformRouteSegment
• platformFolderName (default: platformRouteSegment)
• landingDropdownLabel (default: platformName)
• landingDropdownItemLabel (default: platformName)

Rule categories by priority

Output: view inventory template

UserRole: <role name>
Public views (unauthenticated):
- <View Title> -> <route> (source: <file>)

Authenticated views:
- <View Title> -> <route> (source: <file>)

Role-specific views:
- <View Title> -> <route> (role gate: <where>)

Status:
- Recreate in new platform: YES / NO
- Rename required: YES / NO
- New name (if renamed): <confirmed title>
 - Active in UI navigation: YES / NO
 - Evidence of activity: <nav link | redirect | deep link | comment>

Rules (must follow)

• Boilerplate-first: only scaffold confirmed views.
• Confirmation-first: do not scaffold before view list + naming is confirmed.
• Clean naming: no New*, *V2, Temp*, legacy prefixes.
• Legacy isolation: do not import legacy CSS into new platform layouts.
• Shadcn-first: use shadcn components via CLI or MCP.
• Shadcn install: use MCP to add all components upfront, then reuse.
• Shadcn blocks: prefer sidebar-16/sidebar-01, dashboard-01, login-04, signup-02.
• Global CSS baseline: use shadcn create preset (nova/zinc/orange).
• No legacy UI kits: do not use Ant/Chakra/etc in new routes.
• Auth parity: align new auth routes with historical provider and users.
• No legacy CSS: enforce new baseline styles only.
• Keep new routes under app/<platform-segment>.

Platform structure

app/
  <platform-segment>/
    layout.tsx
    (public)/
      layout.tsx
      page.tsx
      <public-views>/
    (app)/
      layout.tsx
      <auth-views>/

Verification

• Public routes load unauthenticated.
• Authenticated routes redirect when unauthenticated.
• Role-gated routes block unauthorized roles.
• Landing dropdown navigates to /<platform-segment>.
• No console errors on load.

Version policy

Use the latest stable versions of next, react, tailwindcss, and shadcn/ui.
