+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Skybridge is an all-in-one "startup starterpack" monolith application designed to provide everything needed to start a software company with a single platform. Built with a microfrontend architecture, it combines multiple business-critical services including API key management, user authentication, permissions, and a modular plugin system for additional business applications.
+
+**Key Technologies:**
+- **Backend**: Go 1.23+ with Gin router, PostgreSQL, JWT tokens  
+- **Frontend**: React 18+ with TypeScript, Mantine UI components
+- **Module Federation**: Webpack 5 Module Federation for plugin architecture
+- **Infrastructure**: Podman/Docker Compose, Nginx
+- **Security**: HMAC token signing, RBAC permissions, rate limiting
+
+## Startup Platform Architecture
+
+### Business Applications (Microfrontends)
+```

+
+### Plugin Architecture (Module Federation)
+- **Shell Dashboard (port 3000)**: Central hub for all business applications
+- **KMS Module (port 3002)**: API key and authentication management
+- **Demo Module (port 3001)**: Template for building new business modules
+- **Extensible Design**: Easy addition of new business applications (CRM, billing, analytics, etc.)
+
+### Backend Architecture (KMS)
+```
+cmd/server/          - Application entry point  
+internal/            - Go backend core logic

+└── database/        - Database connection and migrations
+```
+
+## Development Commands
+
+### Startup Platform Development
+
+```bash
+# Start complete platform in development mode (run in separate terminals)
+
+# Terminal 1: Main Dashboard Shell
+cd web
+npm install
+npm run dev        # Central dashboard on port 3000
+
+# Terminal 2: KMS Business Module
+cd kms/web
+npm install  
+npm run dev        # API Key Management on port 3002
+
+# Terminal 3: Demo/Template Module
+cd demo  
+npm install
+npm run dev        # Plugin template on port 3001
+
+# Production build
+npm run build      # In each business module directory
+```
+
+### Platform Backend Development
+
+```bash
+# Start core platform backend with authentication services
+cd kms
+INTERNAL_HMAC_KEY=test-hmac-key JWT_SECRET=test-jwt-secret AUTH_SIGNING_KEY=test-signing-key go run cmd/server/main.go
+
+# Build platform backend
+go build -o platform-server ./cmd/server
+
+# Run platform tests
+go test -v ./test/...
+
+# Test specific business modules
+go test -v ./test/ -run TestApplicationCRUD
+go test -v ./test/ -run TestStaticTokenWorkflow
+```
+
+### Full Platform Deployment (Recommended)
+
+**CRITICAL**: This project uses `podman-compose`, not `docker-compose`.
+
+```bash
+# Start complete startup platform (database, API, all business modules)
+podman-compose up -d
+
+# Start with forced rebuild after code changes  
+podman-compose up -d --build
+
+# View platform logs
+podman-compose logs -f kms-api-service
+podman-compose logs -f postgres
+
+# Stop entire platform
+podman-compose down
+
+# Check platform health
+curl http://localhost:8081/health
+```
+
+### Database Operations
+
+**CRITICAL**: All database operations use `podman exec` commands.
+
+```bash
+# Access database shell
+podman exec -it kms-postgres psql -U postgres -d kms
+
+# Run SQL commands via exec
+podman exec -it kms-postgres psql -U postgres -c "SELECT * FROM applications LIMIT 5;"
+
+# Check tables
+podman exec -it kms-postgres psql -U postgres -d kms -c "\dt"
+
+# Reset test database  
+podman exec -it kms-postgres psql -U postgres -c "DROP DATABASE IF EXISTS kms_test; CREATE DATABASE kms_test;"
+```
+
+## Key Architecture Patterns
+
+### Business Module Plugin System
+- **Shell Dashboard** (`web/webpack.config.js`): Central hub consuming all business modules
+- **Business Modules** (`kms/web/webpack.config.js`, `demo/webpack.config.js`): Independent applications exposing functionality
+- **Shared Infrastructure**: React, Mantine, icons shared across all business modules
+
+### Startup Platform Routing
+- **Central routing**: `/app/{businessModule}/*` handled by shell dashboard
+- **Module autonomy**: Each business application handles internal navigation independently  
+- **Isolated contexts**: No React Router conflicts between business modules
+
+### Core Authentication System (KMS Module)
+The platform's authentication system uses **exact permission names** (not wildcards):
+- **Application management**: `app.read`, `app.write`, `app.delete`
+- **Token operations**: `token.read`, `token.create`, `token.revoke` 
+- **Repository access**: `repo.read`, `repo.write`, `repo.admin`
+- **Permission management**: `permission.read`, `permission.write`, `permission.grant`, `permission.revoke`
+
+### Business Application Types
+Valid application configurations for the platform:
+- `"static"` - Service-to-service authentication for business modules
+- `"user"` - User authentication for startup team members
+
+### Ownership Models
+Platform supports different ownership structures:
+- `"individual"` - Individual founder/employee ownership
+- `"team"` - Team/department ownership
+
+## Important Development Notes
+
+### Business Module Development
+- **Port allocation**: Dashboard:3000, Demo:3001, KMS:3002, [Future modules:3003+]
+- **Environment variables**: All business modules require `webpack.DefinePlugin` for process.env
+- **Shared dependencies**: Must match versions across all business modules
+- **Navigation**: Use `window.history.pushState()` and custom events for inter-module routing
+- **Local Development**: Do not start webpack microfrontends as they are already running locally
+
+### Platform API Integration
+- **Base URL**: `http://localhost:8080` (development)
+- **Authentication**: Header-based with `X-User-Email: admin@example.com`
+- **Duration format**: Convert human-readable formats like "24h" to seconds (86400) for API
+- **Permission validation**: Use exact permission names from database, not wildcards
+
+### Startup Platform UI Standards
+- **UI Framework**: Mantine v7.0.0 (consistent across all business modules)
+- **Icons**: Tabler Icons React (shared icon system)
+- **Forms**: Mantine Form with validation (standardized form handling)
+- **Notifications**: Mantine Notifications (unified notification system)
+
+### Critical Platform Configuration
+```bash
+# Platform Backend Environment Variables (Required)
+INTERNAL_HMAC_KEY=<secure-hmac-key-32-chars-min>
+JWT_SECRET=<secure-jwt-secret-32-chars-min>  
+AUTH_SIGNING_KEY=<secure-auth-key-32-chars-min>
+
+# Platform Database
+DB_HOST=postgres  # Use 'postgres' for containers
+DB_PORT=5432
+DB_NAME=kms
+DB_USER=postgres  
+DB_PASSWORD=postgres
+
+# Startup Platform Authentication
+AUTH_PROVIDER=header
+AUTH_HEADER_USER_EMAIL=X-User-Email
+```
+
+### Testing & Debugging
+- **Platform E2E Tests**: `./kms/test/e2e_test.sh` for core authentication system
+- **Test Users**: `admin@example.com`, `test@example.com`, `limited@example.com`
+- **Service Ports**: API:8080, Nginx:8081, Dashboard:3000, DB:5432
+- **Debug Business Modules**: Check browser network tab for remoteEntry.js loading from each module
+
+### Build & Deployment
+- **Development**: Run dashboard shell + all business modules + platform backend
+- **Container Issues**: Use `podman-compose build --no-cache` if changes don't appear
+- **Module Federation**: All business modules must be running for dashboard to load them
+- **Production**: Build all business modules and serve via nginx with proper CORS headers
+
+## Security Considerations
+- All platform tokens use HMAC signing with secure keys
+- Permission validation at both API and UI levels across all business modules
+- Rate limiting and comprehensive audit logging for startup compliance
+- CORS configured for secure business module communication
+- Never commit secrets or API keys to repository
+
+## Adding New Business Modules
+To extend the startup platform with new business applications (CRM, billing, analytics, etc.):
+
+1. **Create new module directory** following the pattern of `demo/` or `kms/web/`
+2. **Configure Module Federation** in webpack.config.js to expose the module
+3. **Update shell dashboard** (`web/webpack.config.js`) to consume the new remote
+4. **Add to navigation** in `web/src/components/Navigation.tsx`
+5. **Follow UI standards** using Mantine components and shared dependencies
+6. **Implement authentication** using the platform's permission system
+7. **Test integration** ensuring the module loads properly in the dashboard

+- **Rationale**: Shell app is primarily navigation/layout, minimal form/table needs
+- **Build Status**: ✅ Successful
+
+## Architecture Benefits Achieved
+
+### 🎯 Code Standardization
+- **Consistent Form Patterns**: All forms now use declarative field configuration
+- **Unified Table Interface**: Standardized search, pagination, CRUD operations
+- **Shared Validation**: Common validation rules across all microfrontends
+
+### 📉 Code Reduction
+- **UserSidebar**: 250 lines → 80 lines (70% reduction)
+- **Applications**: Complex table implementation → clean configuration
+- **Overall**: Estimated 60-70% reduction in form/table boilerplate across platform
+
+### 🔧 Maintainability Improvements
+- **Single Source of Truth**: Component logic centralized in `web-components`
+- **Consistent Updates**: Bug fixes and features propagate to all microfrontends
+- **Type Safety**: Shared TypeScript interfaces ensure consistency
+
+### 🚀 Developer Experience
+- **Faster Development**: New forms/tables can be built with configuration vs custom code
+- **Consistent UX**: Users experience uniform behavior across all applications
+- **Easy Onboarding**: New developers learn one component system
+
+## Technical Implementation
+
+### Package Management
+```json
+{
+  "dependencies": {
+    "@skybridge/web-components": "workspace:*",
+    "@mantine/modals": "^7.0.0"  // Added where needed
+  }
+}
+```
+
+### Typical Integration Pattern
+```tsx
+// Before: 200+ lines of custom form code
+// After: Clean configuration
+const fields: FormField[] = [
+  { name: 'email', type: 'email', required: true },
+  { name: 'role', type: 'select', options: [...] }
+];
+
+return (
+  <FormSidebar
+    fields={fields}
+    onSubmit={handleSubmit}
+    editItem={editItem}
+  />
+);
+```
+
+## Current Status
+
+### ✅ Completed Tasks
+1. ✅ Web components library built and distributed
+2. ✅ All 5 microfrontends successfully integrated
+3. ✅ FormSidebar components refactored across platform
+4. ✅ DataTable components implemented with consistent APIs
+5. ✅ All builds passing with shared dependencies
+
+### Build Verification
+All microfrontends build successfully with only expected asset size warnings:
+- ✅ `user/web`: 6.6s build time
+- ✅ `kms/web`: 6.8s build time  
+- ✅ `demo`: 6.4s build time
+- ✅ `faas/web`: 6.7s build time
+- ✅ `web`: 12.3s build time
+
+## Additional Shared Component Integration (Final Phase)
+
+### ✅ SidebarLayout Standardization - **NEW**
+- **Status**: Completed across all microfrontends with sidebars
+- **Problem Solved**: Fixed sidebar overlay behavior where main content was covered instead of shrinking
+- **New Components Added**:
+  - `SidebarLayout`: Manages main content area resizing when sidebars open
+  - `Sidebar` (enhanced): Added `layoutMode` prop for integration with SidebarLayout
+- **Components Updated**:
+  - `Applications.tsx` (KMS): Replaced Stack with manual margins → SidebarLayout + enhanced Sidebar
+  - `UserManagement.tsx` (User): Replaced Stack with manual margins → SidebarLayout  
+  - `App.tsx` (FaaS): Replaced Stack with manual margins → Optimized margin calculation for existing fixed sidebars
+- **Benefits**: Main content now properly shrinks to accommodate sidebars, providing better UX and preventing content from being hidden
+
+## Additional Shared Component Integration (Previous Phase)
+
+### ✅ StatusBadge Integration
+- **Status**: Completed across FaaS and KMS modules
+- **Components Updated**:
+  - `ExecutionModal.tsx` & `ExecutionSidebar.tsx` (FaaS): Replaced duplicate `getStatusColor` function with `ExecutionStatusBadge`
+  - `Audit.tsx` (KMS): Replaced custom status logic with standardized `StatusBadge` component
+- **Benefits**: Eliminated duplicate status color mapping logic, consistent status display across platform
+- **Code Reduction**: ~30 lines of duplicate status logic removed per component
+
+### ✅ Pattern Consolidation Analysis
+- **Duplicate Status Logic**: Found and replaced in 4+ components across microfrontends
+- **Shared Loading States**: Available but not universally adopted (complex implementation differences)
+- **Empty State Patterns**: Standardized components available for future adoption
+- **Form Sidebar Usage**: Already well-adopted in User and Application management
+
+## Updated Architecture Benefits
+
+### 🎯 Enhanced Code Standardization
+- **Consistent Status Indicators**: All status badges now use standardized color mapping
+- **Unified Badge Variants**: Execution, severity, runtime, and application type badges standardized
+- **Cross-Platform Consistency**: Status colors consistent between KMS audit logs and FaaS execution displays
+
+### 📉 Final Code Reduction Metrics
+- **UserSidebar**: 250 lines → 80 lines (70% reduction)
+- **Applications Table**: Complex implementation → clean DataTable configuration
+- **Status Logic**: ~120 lines of duplicate status functions eliminated
+- **Sidebar Layout Logic**: ~90 lines of manual margin management replaced with declarative SidebarLayout
+- **Overall Platform**: Estimated 70-80% reduction in form/table/status/layout boilerplate
+
+### 🔧 Maintainability Improvements
+- **Centralized Status Logic**: All status colors managed in single StatusBadge component
+- **Standardized Layout Behavior**: SidebarLayout ensures consistent sidebar behavior across all microfrontends
+- **Type Safety**: StatusBadge variants and SidebarLayout props ensure consistent usage patterns
+- **Easy Updates**: Status color changes and sidebar behavior improvements propagate automatically to all components
+
+## Current State Assessment
+
+### ✅ Fully Integrated Components
+1. **User Management** - Complete FormSidebar and DataTable adoption
+2. **KMS Applications** - Complete FormSidebar and DataTable adoption  
+3. **FaaS Functions** - DataTable with hybrid FormSidebar approach
+4. **Demo Application** - Full shared component showcase
+5. **Shell Dashboard** - Appropriate minimal integration
+
+### ⚡ StatusBadge Adoption Completed
+- **FaaS Execution States**: ExecutionStatusBadge integrated
+- **KMS Audit Logs**: StatusBadge for event status
+- **Available Variants**: Status, Role, Runtime, Type, Severity, Execution
+- **Consistent Color Mapping**: Standardized across all business domains
+
+### 🎨 SidebarLayout Integration Completed
+- **KMS Applications**: SidebarLayout with ApplicationSidebar (450px width)
+- **User Management**: SidebarLayout with UserSidebar (400px width)  
+- **FaaS Functions**: Optimized margin calculation for dual fixed sidebars (600px width each)
+- **Behavior**: Main content shrinks instead of being covered by sidebars
+- **Mobile Support**: ResponsiveSidebarLayout available for mobile-friendly overlays
+- **Compatibility**: Works with both new SidebarLayout pattern and existing fixed-positioned sidebars
+
+### 🔄 Remaining Opportunities
+1. **Loading/Empty States**: Complex patterns exist but require careful migration
+2. **Additional Status Types**: Future business modules can extend StatusBadge variants
+3. **Performance Optimization**: Monitor shared component bundle impact
+
+## Final Recommendations
+
+### 🎯 Implementation Complete
+- **Core Integration**: All major form and table components successfully migrated

+# Skybridge FaaS Client
+
+A lightweight Go client library for interacting with the Skybridge Function-as-a-Service (FaaS) platform.
+
+## Installation
+
+```bash
+go get github.com/RyanCopley/skybridge/faas-client
+```
+
+## Usage
+
+### Basic Client Setup
+
+```go
+package main
+
+import (
+    "context"
+    "log"
+    
+    faasclient "github.com/RyanCopley/skybridge/faas-client"
+)
+
+func main() {
+    // Create a new client
+    client := faasclient.NewClient(
+        "http://localhost:8080", // FaaS API base URL
+        faasclient.WithUserEmail("admin@example.com"), // Authentication
+    )
+    
+    // Use the client...
+}
+```
+
+### Authentication Options
+
+```go
+// Using user email header (for development)
+client := faasclient.NewClient(baseURL, 
+    faasclient.WithUserEmail("user@example.com"))
+
+// Using custom auth headers
+client := faasclient.NewClient(baseURL,
+    faasclient.WithAuth(map[string]string{
+        "Authorization": "Bearer " + token,
+        "X-User-Email":  "user@example.com",
+    }))
+
+// Using custom HTTP client
+httpClient := &http.Client{Timeout: 30 * time.Second}
+client := faasclient.NewClient(baseURL,
+    faasclient.WithHTTPClient(httpClient))
+```
+
+### Function Management
+
+#### Creating a Function
+
+```go
+req := &faasclient.CreateFunctionRequest{
+    Name:    "my-function",
+    AppID:   "my-app",
+    Runtime: faasclient.RuntimeNodeJS18,
+    Image:   "node:18-alpine", // Optional, auto-selected if not provided
+    Handler: "index.handler",
+    Code:    "exports.handler = async (event) => { return 'Hello World'; }",
+    Environment: map[string]string{
+        "NODE_ENV": "production",
+    },
+    Timeout: faasclient.Duration(30 * time.Second),
+    Memory:  512,
+    Owner: faasclient.Owner{
+        Type:  faasclient.OwnerTypeIndividual,
+        Name:  "John Doe",
+        Owner: "john@example.com",
+    },
+}
+
+function, err := client.CreateFunction(context.Background(), req)
+if err != nil {
+    log.Fatal(err)
+}
+
+log.Printf("Created function: %s (ID: %s)", function.Name, function.ID)
+```
+
+#### Getting a Function

+
+### Execution Management
+
+#### Getting Execution Details
+

+
+```go
+// List all executions
+response, err := client.ListExecutions(context.Background(), nil, 50, 0)
+if err != nil {
+    log.Fatal(err)
+}
+
+// List executions for a specific function

+    log.Fatal(err)
+}
+
+for _, exec := range response.Executions {
+    log.Printf("Execution: %s, Status: %s", exec.ID, exec.Status)
+}
+```
+
+#### Canceling an Execution
+
+```go
+err := client.CancelExecution(context.Background(), executionID)
+if err != nil {
+    log.Fatal(err)
+}
+```
+
+#### Getting Execution Logs
+
+```go
+logs, err := client.GetExecutionLogs(context.Background(), executionID)
+if err != nil {
+    log.Fatal(err)
+}
+
+for _, logLine := range logs.Logs {
+    log.Printf("Log: %s", logLine)
+}
+```
+
+#### Getting Running Executions
+
+```go
+response, err := client.GetRunningExecutions(context.Background())
+if err != nil {
+    log.Fatal(err)
+}
+
+log.Printf("Running executions: %d", response.Count)
+for _, exec := range response.Executions {
+    log.Printf("Running: %s (Function: %s)", exec.ID, exec.FunctionID)
+}
+```
+
+## Types
+
+The client provides comprehensive type definitions that match the FaaS API:
+
+- `FunctionDefinition` - Complete function metadata
+- `FunctionExecution` - Execution details and results
+- `RuntimeType` - Supported runtimes (NodeJS18, Python39, Go120, Custom)
+- `ExecutionStatus` - Execution states (Pending, Running, Completed, Failed, etc.)
+- `Owner` - Ownership information
+- Request/Response types for all operations
+
+## Error Handling
+
+The client provides detailed error messages that include HTTP status codes and response bodies:
+
+```go
+function, err := client.GetFunction(ctx, nonExistentID)
+if err != nil {
+    // Error will include status code and details
+    log.Printf("Error: %v", err) // "get function failed with status 404: Function not found"
+}
+```
+
+## Architecture Benefits
+
+This client package is designed as a lightweight, standalone library that:
+
+- **No heavy dependencies**: Only requires `google/uuid` 
+- **Zero coupling**: Doesn't import the entire FaaS service
+- **Modular**: Can be used by any service in your monolith
+- **Type-safe**: Comprehensive Go types for all API operations
+- **Flexible auth**: Supports multiple authentication methods

+# Skybridge FaaS Implementation Guide
+
+This document explains the implementation of the Function-as-a-Service (FaaS) component in Skybridge, specifically focusing on the Docker runtime implementation that replaced the original mock implementation.
+
+## Overview
+
+The Skybridge FaaS platform allows users to deploy and execute functions in isolated containers. The implementation consists of several key components:
+
+1. **Function Management**: CRUD operations for function definitions
+2. **Execution Engine**: Runtime backend for executing functions
+3. **Repository Layer**: Data persistence for functions and executions
+4. **Services Layer**: Business logic implementation
+5. **API Layer**: RESTful interface for managing functions
+
+## Docker Runtime Implementation
+
+The original implementation contained a mock Docker runtime (`faas/internal/runtime/docker/simple.go`) that didn't actually interact with Docker. The new implementation provides real container execution capabilities.
+
+### Key Features Implemented
+
+1. **Real Docker Client Integration**: Uses the official Docker client library to communicate with the Docker daemon
+2. **Container Lifecycle Management**: Creates, starts, waits for, and cleans up containers
+3. **Image Management**: Pulls images when they don't exist locally
+4. **Resource Limiting**: Applies memory limits to containers
+5. **Input/Output Handling**: Passes input to functions and captures output
+6. **Logging**: Retrieves container logs for debugging
+7. **Health Checks**: Verifies Docker daemon connectivity
+
+### Implementation Details
+
+#### Container Creation
+
+The `createContainer` method creates a Docker container with the following configuration:
+
+- **Environment Variables**: Function environment variables plus input data
+- **Resource Limits**: Memory limits based on function configuration
+- **Attached Streams**: STDOUT and STDERR for log capture
+
+#### Function Execution Flow
+
+1. **Container Creation**: Creates a container from the function's Docker image
+2. **Container Start**: Starts the container execution
+3. **Wait for Completion**: Waits for the container to finish execution
+4. **Result Collection**: Gathers output, logs, and execution metadata
+5. **Cleanup**: Removes the container to free resources
+
+#### Error Handling
+
+The implementation includes comprehensive error handling:
+
+- **Connection Errors**: Handles Docker daemon connectivity issues
+- **Container Errors**: Manages container creation and execution failures
+- **Resource Errors**: Handles resource constraint violations
+- **Graceful Cleanup**: Ensures containers are cleaned up even on failures
+
+## Testing
+
+### Unit Tests
+
+Unit tests are located in `faas/test/integration/` and cover:
+
+- Docker runtime health checks
+- Container creation and execution
+- Error conditions
+
+### Example Function
+
+An example "Hello World" function is provided in `faas/examples/hello-world/` to demonstrate:
+
+- Function structure and implementation
+- Docker image creation
+- Local testing
+- Deployment to Skybridge FaaS
+
+## Deployment
+
+### Prerequisites
+
+1. Docker daemon running and accessible
+2. Docker socket mounted to the FaaS service container (as shown in `docker-compose.yml`)
+3. Required permissions to access Docker
+
+### Configuration
+
+The FaaS service reads configuration from environment variables:
+
+- `FAAS_DEFAULT_RUNTIME`: Should be set to "docker"
+- Docker socket path: Typically `/var/run/docker.sock`
+
+## Security Considerations
+
+The current implementation has basic security features:
+
+- **Container Isolation**: Functions run in isolated containers
+- **Resource Limits**: Prevents resource exhaustion
+- **Image Verification**: Only pulls trusted images
+
+For production use, consider implementing:
+
+- Container user restrictions
+- Network isolation
+- Enhanced logging and monitoring
+- Authentication and authorization for Docker operations
+
+## Performance Optimizations
+
+Potential performance improvements include:
+
+- **Image Caching**: Pre-pull commonly used images
+- **Container Pooling**: Maintain a pool of ready containers
+- **Parallel Execution**: Optimize concurrent function execution
+- **Resource Monitoring**: Track and optimize resource usage
+
+## Future Enhancements
+
+Planned enhancements include:
+
+1. **Multiple Runtime Support**: Add support for Podman and other container runtimes
+2. **Advanced Resource Management**: CPU quotas, disk limits
+3. **Enhanced Monitoring**: Detailed metrics and tracing
+4. **Improved Error Handling**: More granular error reporting
+5. **Security Hardening**: Additional security measures for container execution
+
+## API Usage
+
+The FaaS API provides endpoints for:
+
+- **Function Management**: Create, read, update, delete functions
+- **Deployment**: Deploy functions to prepare for execution
+- **Execution**: Execute functions synchronously or asynchronously
+- **Monitoring**: View execution status, logs, and metrics
+
+Refer to the API documentation endpoint (`/api/docs`) for detailed information.

+# Hello World Function Example
+
+This is a simple example function that demonstrates how to create and deploy functions in the Skybridge FaaS platform.
+
+## Function Description
+
+The function takes a JSON input with an optional `name` field and returns a greeting message.
+
+### Input Format
+```json
+{
+  "name": "John"
+}
+```
+
+### Output Format
+```json
+{
+  "message": "Hello, John!",
+  "input": {
+    "name": "John"
+  }
+}
+```
+
+## Building the Function
+
+To build the function as a Docker image:
+
+```bash
+docker build -t hello-world-function .
+```
+
+## Testing the Function Locally
+
+To test the function locally:
+
+```bash
+# Test with a name
+docker run -e FUNCTION_INPUT='{"name": "Alice"}' hello-world-function
+
+# Test without a name (defaults to "World")
+docker run hello-world-function
+```
+
+## Deploying to Skybridge FaaS
+
+Once you have the Skybridge FaaS platform running, you can deploy this function using the API:
+
+1. Create the function:
+```bash
+curl -X POST http://localhost:8083/api/functions \
+  -H "Content-Type: application/json" \
+  -H "X-User-Email: test@example.com" \
+  -d '{
+    "name": "hello-world",
+    "image": "hello-world-function",
+    "runtime": "custom",
+    "memory": 128,
+    "timeout": "30s"
+  }'
+```
+
+2. Deploy the function:
+```bash
+curl -X POST http://localhost:8083/api/functions/{function-id}/deploy \
+  -H "X-User-Email: test@example.com"
+```
+
+3. Execute the function:
+```bash
+curl -X POST http://localhost:8083/api/functions/{function-id}/execute \
+  -H "Content-Type: application/json" \
+  -H "X-User-Email: test@example.com" \
+  -d '{"input": {"name": "Bob"}}'
