+# Basic Protocol Examples
+
+A standalone package containing comprehensive examples demonstrating core ObjectStack protocols and features.
+
+## 📦 Package Information
+
+- **Package**: `@objectstack/example-basic`
+- **Type**: Demonstration/Reference
+- **Status**: Standalone examples with type checking
+
+## 🚀 Usage
+
+### Build and Type Check
+
+```bash
+# From monorepo root
+pnpm install
+
+# Build the spec package first
+pnpm --filter @objectstack/spec build
+
+# Type check the examples
+pnpm --filter @objectstack/example-basic typecheck
+
+# Or run directly with tsx
+npx tsx examples/basic/stack-definition-example.ts
+```
+
+### Running Examples
+
+Each example file can be run independently with `tsx`:
+
+```bash
+# Run a specific example
+npx tsx examples/basic/ai-rag-example.ts
+
+# Or uncomment the demonstration function calls at the end of each file
+```
+
+## 📚 Examples
+
+### Stack Definition
+**File:** [`stack-definition-example.ts`](./stack-definition-example.ts)
+
+Demonstrates the `defineStack()` helper for creating comprehensive ObjectStack configurations:
+- Minimal stack setup
+- Task management application with Objects, UI, and Workflows
+- CRM with AI agent integration
+- Type-safe configuration patterns
+
+**Key Concepts:**
+- Manifest configuration
+- Object and Field definitions
+- UI components (Apps, Views, Dashboards)
+- Automation (Workflows)
+- Security (Roles, Permissions)
+- AI Agents
+
+### Capabilities Configuration
+**File:** [`capabilities-example.ts`](./capabilities-example.ts)
+
+Shows how to define runtime capabilities for ObjectStack instances:
+- Production environment with full features
+- Development environment with minimal features
+- AI-focused environment optimized for RAG
+- Capability checking helpers
+
+**Key Concepts:**
+- ObjectQL (Data) capabilities
+- ObjectUI (UI) capabilities
+- ObjectOS (System) capabilities
+- Environment-specific configurations
+
+### API Discovery
+**File:** [`api-discovery-example.ts`](./api-discovery-example.ts)
+
+Demonstrates the API Discovery protocol for runtime introspection:
+- Complete discovery response
+- Development mode discovery
+- Adaptive client behavior
+- AI agent system prompt generation
+
+**Key Concepts:**
+- System identity and versioning
+- Available API endpoints (REST, GraphQL, OData, WebSocket)
+- Runtime capabilities
+- Authentication configuration
+- Feature flags
+
+### AI & RAG Pipeline
+**File:** [`ai-rag-example.ts`](./ai-rag-example.ts)
+
+Shows Retrieval-Augmented Generation (RAG) pipeline configuration:
+- Document ingestion and chunking
+- Vector embeddings and storage
+- Semantic search and retrieval
+- Context assembly for LLMs
+- AI agent with RAG integration
+
+**Key Concepts:**
+- RAG pipeline configuration
+- Document processing
+- Vector database integration
+- Hybrid search (vector + keyword)
+- Reranking for better results
+- Context template formatting
+
+### Auth & Permissions
+**File:** [`auth-permission-example.ts`](./auth-permission-example.ts)
+
+Demonstrates authentication and authorization systems:
+- User identity and sessions
+- Role-based access control (RBAC) with hierarchy
+- Object and field-level permissions
+- Row-level security (RLS)
+- Sharing rules for data access
+- Territory management
+
+**Key Concepts:**
+- User authentication and profiles
+- Role hierarchy and inheritance
+- Permission sets
+- Granular access control
+- Dynamic data filtering
+- Territory-based assignments
+
+### Automation & Workflows
+**File:** [`automation-example.ts`](./automation-example.ts)
+
+Shows automation capabilities in ObjectStack:
+- Workflow rules for field updates
+- Email alerts and notifications
+- Automatic record creation
+- Multi-step approval processes
+- Screen flows with user interaction
+- ETL processes for data integration
+
+**Key Concepts:**
+- Event-driven automation
+- Scheduled workflows (cron)
+- Approval hierarchies
+- Visual process automation
+- Data transformation pipelines
+- Error handling and notifications
+
+## 🎯 Usage
+
+These examples are TypeScript files in a proper package that can be:
+
+1. **Type checked:**
+   ```bash
+   pnpm --filter @objectstack/example-basic typecheck
+   ```
+
+2. **Run directly:**
+   ```bash
+   npx tsx examples/basic/stack-definition-example.ts
+   ```
+
+3. **Used as references:**
+   Import types and patterns in your own projects
