**CodeEntity**: Classes, functions, variables with complexity metrics - **Pattern**: Design patterns (Singleton, Factory, Observer, etc.) - **Rule**: Business rules and coding standards - **Standard**: Naming conventions and formatting rules - **TechnicalDebt**: Identified debt with severity and remediation - **HardwareComponent**: Arduino pins, sensors, actuators - **TimingConstraint**: Real-time timing requirements ### Relationship Types - **IMPLEMENTS**: Code implements design pattern - **VIOLATES**: Code violates rule or standard - **DEPENDS_ON**: Dependency relationships - **COUPLED_WITH**: Code coupling analysis - **USES_HARDWARE**: Hardware component usage - **HANDLES**: Interrupt handling relationships ## 🚀 Usage Examples ### Define Domain Architecture ```markdown Use the `define_domain_ontology` tool to establish your system architecture: Entities: - UserService (authentication, authorization) - ProductCatalog (inventory, pricing) - OrderProcessor (workflow, payments) Relationships: - UserService AUTHENTICATES OrderProcessor - ProductCatalog PROVIDES OrderProcessor Business Rules: - "All API endpoints must have authentication" - "Database connections must use connection pooling" - "Error responses must include correlation IDs" Coding Standards: - Use TypeScript for type safety - Follow SOLID principles - Maximum function complexity: 10 ``` ### Analyze Arduino Project ```markdown Use the `analyze_arduino_sketch` tool for embedded analysis: Sketch path: "./arduino/sensor_hub/sensor_hub.ino" Target board: "mega2560" Include libraries: true Returns comprehensive analysis: - Memory usage: RAM 1.2KB/8KB, Flash 15KB/256KB - Pin conflicts: None detected - Interrupt usage: 2/6 available - Timing violations: Loop takes 45ms (target: <50ms) - Optimization suggestions: Use PROGMEM for strings ``` ### Generate Context-Aware Code ```markdown Use the `generate_code_with_context` tool: Requirement: "Create API endpoint for user registration" Patterns to apply: ["repository", "validation", "error-handling"] Constraints: {"language": "typescript", "framework": "express"} Generates: -
