+# AI Context File for MSAL Custom Authentication Project
+
+## 📦 Description
+
+MSAL Custom Authentication is a TypeScript-based library that extends Microsoft's Authentication Library (MSAL) to enable customized authentication experiences in modern web applications. Key features include:
+
+-   **Flexible Authentication Flows:**
+
+    -   Sign-in with username/password or passwordless options
+    -   Sign-up with customizable user attributes
+    -   Password reset and account recovery
+    -   Account management and token handling
+
+-   **UI Framework Agnostic:**
+
+    -   Built as a headless authentication library
+    -   Complete control over UI implementation
+    -   Separation of authentication logic from presentation
+    -   Seamless integration with any UI framework (React, Angular, Vue, vanilla JavaScript)
+
+-   **Developer-Friendly:**
+    -   Strongly typed APIs for enhanced development experience
+    -   Comprehensive error handling and logging
+    -   Built-in state management for auth flows
+    -   Clear separation of concerns for better maintainability
+
+## 🧱 Technology Stack
+
+-   **Language & Runtime:**
+    -   TypeScript 5.7+
+    -   Node.js 10+
+-   **Core Dependencies:**
+    -   @azure/msal-browser - Core MSAL browser library
+-   **Build System:**
+    -   Rollup.js - Module bundling
+    -   TypeScript compiler
+    -   Babel - JavaScript compilation
+-   **Testing & Quality:**
+    -   Jest - Testing framework with JSDOM environment
+    -   ESLint - Code linting

+
+## 🔁 Patterns & Conventions
+
+### 📌 General
+
+-   Always define classes and significant logic in separate TypeScript files under `src/core/`.
+-   Public-facing APIs should be exposed through `src/index.ts`.
+-   Avoid embedding complex logic directly within entry points or utility scripts.
+
+### 📌 Async Method Handling
+
+-   All methods interacting with network or authentication flows must be marked `async`.
+-   Properly await promises and handle exceptions internally using try-catch.
+
+```typescript
+async signInUser(credentials): Promise<AuthenticationResult> {
+  try {
+    const result = await this.performAuthentication(credentials);
+    return result;
+  } catch (error) {
+    logger.error("Sign-in error:", error);
+    throw error;
+  }
+}
+```
+
+### 📌 Error Handling
+
+-   Use centralized logging for all caught exceptions (`logger.error()` for errors).
+-   Return standardized error objects to maintain consistency across API responses.
+
+### 📌 Testing
+
+-   Unit tests must be located under `/test` directory, following `.spec.ts` naming convention.
+-   Maintain high test coverage, especially for core authentication flows.
+
+## 🗝️ Key Files
+
+-   `src/index.ts`: Exports all public classes, interfaces, types, and constants.
+-   `src/CustomAuthPublicClientApplication.ts`: Main application class implementing custom authentication flows.
+-   `src/ICustomAuthPublicClientApplication.ts`: Interface definition for the main application.
+-   `src/CustomAuthActionInputs.ts`: Type definitions for authentication flow inputs.
+-   `src/CustomAuthConstants.ts`: Shared constants used throughout the library.
+-   `src/UserAccountAttributes.ts`: User account attribute management.
+-   `src/configuration/`: Configuration and initialization related files.
+-   `src/controller/`: Authentication flow controllers.
+-   `src/core/`: Core error handling and utilities.
+-   `src/get_account/`: Account retrieval and management.
+-   `src/sign_in/`, `src/sign_up/`, `src/reset_password/`: Authentication flow implementations.
+-   `package.json`: Manage dependencies and npm scripts.
+-   `rollup.config.js`: Defines build steps.
+-   `jest.config.cjs`: Testing framework setup.
+
+## 🎯 Goals for Copilot / AI Tools
+
+When modifying or extending authentication functionality:
+
+-   Keep main application logic in `CustomAuthPublicClientApplication.ts` focused on high-level flow coordination.
+-   Implement specific authentication flows in their dedicated directories (`sign_in/`, `sign_up/`, `reset_password/`).
+-   Place shared utilities and error handling in `src/core/`.
+-   Implement flow controllers in `src/controller/` to manage authentication state and operations.
+-   Define new action inputs in `CustomAuthActionInputs.ts`.
+-   Add any new constants to `CustomAuthConstants.ts`.
+-   Export all public APIs through `src/index.ts`.
+-   Write corresponding tests under `/test` folder immediately.
+-   Ensure proper error handling using the error types defined in `src/core/error/`.
+-   Follow established async patterns for all network and authentication operations.
+-   Use type-safe interfaces and maintain strict type checking throughout the codebase.
