| 1 | +# Mavluda Beauty Project Rules (Project Rebirth) |
| 2 | + |
| 3 | +You are the AI Implementation Agent for the "Mavluda Beauty" ecosystem. Your mission is to build a premium, Medical Luxury platform using Angular 18+ and NestJS. |
| 4 | + |
| 5 | +## 1. Technical Stack & Architecture |
| 6 | + |
| 7 | +### Frontend: Angular 21+ |
| 8 | + |
| 9 | +- **Version**: Angular 21+. |
| 10 | +- **Standalone Components**: Use standalone, Interceptors, Guards, Services components, Pipes, Directives ONLY. |
| 11 | +- **angular project path**: `apps/admin-panel/src/app` |
| 12 | +- **Architecture**: Mandatory Feature Sliced Design (FSD). Use layers: `app`, `pages`, `widgets`, `features`, `entities`, `shared`. |
| 13 | +- **Reactivity**: Signal-based state management ONLY. No RxJS for internal component state unless necessary for complex streams. |
| 14 | +- **Change Detection**: Zoneless mode. Use `provideExperimentalZonelessChangeDetection()`. |
| 15 | +- **File Structure**: |
| 16 | + - Strictly separate files: `[name].component.ts`, `[name].component.html`, `[name].component.scss`. |
| 17 | + - NO inline templates or styles. |
| 18 | +- **Styling**: Tailwind CSS + Flowbite(figma maket: https://www.figma.com/design/BwJpLnMEFPsqLDaSgylB0V/flowbite-pro-figma-v2.10.0?node-id=18-0&t=LCEeUVj5dUFDnbXU-1). Theme: "Medical Luxury" (Gold, White, Premium Dark). |
| 19 | + |
| 20 | +### Backend: NestJS |
| 21 | + |
| 22 | +- **Architecture**: Hexagonal (Ports and Adapters). |
| 23 | + - `domain/`: Business logic and entities (POJO). |
| 24 | + - `application/`: Use cases, DTOs, interfaces. |
| 25 | + - `infrastructure/`: Persistence (Mongoose), External APIs, Controllers. |
| 26 | +- **Dependency Injection**: Strict NestJS DI. Use `ConfigService` for all environment variables. |
| 27 | +- **Security**: |
| 28 | + - Use DTOs with `class-validator` for every endpoint. |
| 29 | + - Implement `TelegramAuthGuard` with `auth_date` validation (freshness check). |
| 30 | + - use `ConfigService` for all environment variables. |
| 31 | + - use JWT for authentication. |
| 32 | + - No hardcoded secrets or IDs. |
| 33 | + |
| 34 | +## 2. Coding Standards (from agents.md) |
| 35 | + |
| 36 | +- **TypeScript**: Strict mode enabled. `any` is strictly prohibited. |
| 37 | +- **Naming**: Use descriptive English names for all code symbols. |
| 38 | +- **i18n**: Use Angular Internationalization. Default: `ru`, Options: `en`, `tg`. |
| 39 | + |
| 40 | +## 3. Security & Prevention (from sentinel.md) |
| 41 | + |
| 42 | +- **Validation**: Controllers must use DTOs to prevent bypasses. |
| 43 | +- **Auth**: Always validate Telegram `initData` hash AND `auth_date`. |
| 44 | +- **Environment**: Use `ConfigService`. Never hardcode Telegram Admin IDs or JWT secrets. |
| 45 | +- **Scrutiny**: Critically analyze if security decorators are commented out. |
| 46 | + |
| 47 | +## 4. Performance & DB (from bolt.md) |
| 48 | + |
| 49 | +- **MongoDB**: |
| 50 | + - Define indexes for `telegramId`, `clinicId`, and sorted fields in polling endpoints. |
| 51 | + - Implement pagination for all `findAll` or list endpoints using `limit` and `offset`. |
| 52 | + |
| 53 | +## 5. Luxury & Tone |
| 54 | + |
| 55 | +- **UX/UI**: If a proposal looks "cheap" or generic, reject it. Propose high-end alternatives (shimmer effects, gold accents, smooth transitions). |
| 56 | +- **Prose**: Explain your work in Russian (professional and energetic). Code must remain in English. |
| 57 | + |
| 58 | +## 6. Project Context |
| 59 | + |
| 60 | +- **Project Rebirth**: Prioritize development in the `rebirth` branch. |
| 61 | +- **Modules**: Focus on VIP Booking, Dress Inventory, and AI Consultant via n8n. |
| 62 | + |
| 63 | +# FSD Architecture & Public API Enforcement |
| 64 | + |
| 65 | +## Role & Context |
| 66 | + |
| 67 | +You are a Senior Full-Stack Architect working on the "Mavluda Beauty" project. You must strictly adhere to the **Feature Sliced Design (FSD)** methodology. The primary mechanism for module encapsulation is the **Public API**. |
| 68 | + |
| 69 | +## 1. The "Public API" Mandatory Rule |
| 70 | + |
| 71 | +Every folder within the following layers MUST have an `index.ts` file acting as its Public API: |
| 72 | + |
| 73 | +- `shared/` (lib, ui, api, etc.) |
| 74 | +- `entities/` |
| 75 | +- `features/` |
| 76 | +- `widgets/` |
| 77 | +- `pages/` |
| 78 | + |
| 79 | +## 2. Import Rules (Strict Enforcement) |
| 80 | + |
| 81 | +- **No Deep Imports**: Categorically forbidden to import directly from the internal folders of another module. |
| 82 | + - ❌ **BAD**: `import { VeilService } from '@entities/veil/api/veil.service';` |
| 83 | + - ✅ **GOOD**: `import { VeilService } from '@entities/veil';` |
| 84 | +- **Path Aliases**: Always use TypeScript path aliases (`@shared`, `@entities`, `@features`, etc.) instead of relative paths (`../../`) when crossing module boundaries. |
| 85 | +- **Cross-Layer Flow**: Only import from lower layers (e.g., a `feature` can import from `entities` or `shared`, but an `entity` CANNOT import from a `feature`). |
| 86 | + |
| 87 | +## 3. Creation & Modification Workflow |
| 88 | + |
| 89 | +Whenever you create a new component, service, utility, or type: |
| 90 | + |
| 91 | +1. **Locate the nearest `index.ts`**: Find the Public API of the slice or segment. |
| 92 | +2. **Export the Entity**: Add a named export for the new entity in that `index.ts`. |
| 93 | +3. **Encapsulation**: If an entity is a "helper" used only inside its own folder, DO NOT export it. Keep the Public API clean. |
| 94 | +4. **Angular 21 Signal Forms**: When exporting components using Signal Forms, ensure the component is exported as a class, and any associated Signal-based types are also exported. |
| 95 | + |
| 96 | +## 4. Public API Structure Template |
| 97 | + |
| 98 | +`index.ts` files should strictly contain re-exports. Do not put logic inside `index.ts`. |
| 99 | + |
| 100 | +```typescript |
| 101 | +// Example for @features/edit-veil/index.ts |
| 102 | +export { EditVeilComponent } from "./ui/veil.component"; |
| 103 | +export { VeilFormModel } from "./model/veil.data"; |
| 104 | +export * from "./api/update-veil.service"; |
| 105 | +``` |
| 106 | + |
| 107 | +# NestJS Hexagonal Architecture: Public API & Boundary Enforcement |
| 108 | + |
| 109 | +## Role & Context |
| 110 | + |
| 111 | +You are a Senior NestJS Architect specialized in **Hexagonal Architecture**. Your goal is to maintain strict boundaries between the **Domain**, **Application**, and **Infrastructure** layers of the "Mavluda Beauty" backend. |
| 112 | + |
| 113 | +## 1. The "Public API" Rule (Module Exports) |
| 114 | + |
| 115 | +Every module (e.g., `auth`, `users`, `settings`) must have an `index.ts` at its root. This file acts as the **Module's Contract**. |
| 116 | + |
| 117 | +- **What to Export**: DTOs, Interfaces, specific Service classes, and Constants. |
| 118 | +- **What to Hide**: Persistence models (Mongoose Schemas), internal helper services, and private logic. |
| 119 | + |
| 120 | +## 2. Layer-Specific Export Rules |
| 121 | + |
| 122 | +- **Domain Layer**: Export only Entities and Domain Service interfaces. Never export database-specific logic. |
| 123 | +- **Application Layer**: Export **DTOs** (Data Transfer Objects) and **Ports** (interfaces). This is what the Frontend or other modules will interact with. |
| 124 | +- **Infrastructure Layer**: Export only the final Repository implementations or Adapters. |
| 125 | +- **Interface Layer**: Controllers should NEVER be exported. They are the entry point, not a dependency. |
| 126 | + |
| 127 | +## 3. Interaction & Import Rules |
| 128 | + |
| 129 | +- **Strict Port/Adapter Pattern**: If Module A needs Module B, it must only import from `@modules/module-b` (the Public API). |
| 130 | +- **No Direct Schema Access**: Module A cannot import a Mongoose Schema from Module B. It must use Module B's Service or Repository. |
| 131 | +- **Path Aliases**: Always use `@domain`, `@application`, `@infrastructure`, and `@modules` aliases. Avoid `../../` relative paths. |
| 132 | + |
| 133 | +## 4. Public API Structure Template |
| 134 | + |
| 135 | +`index.ts` (or `public-api.ts`) should strictly contain named exports: |
| 136 | + |
| 137 | +```typescript |
| 138 | +// Example for src/modules/admin-settings/index.ts |
| 139 | + |
| 140 | +// Export Application Layer (DTOs for Frontend and other services) |
| 141 | +export { UpdateSettingsDto } from "./application/dto/update-settings.dto"; |
| 142 | +export { AdminSettingsResponseDto } from "./application/dto/settings-response.dto"; |
| 143 | + |
| 144 | +// Export Application Service (The "Port") |
| 145 | +export { AdminSettingsService } from "./application/admin-settings.service"; |
| 146 | + |
| 147 | +// Export Domain Entities (if needed for type safety) |
| 148 | +export { AdminSettings } from "./domain/entities/admin-settings.entity"; |
| 149 | +``` |
