🚀 Usage Examples

Define Domain Architecture

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

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

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: - Repository pattern implementation - Input validation with Joi schemas - Structured error handling - Comprehensive logging - Unit test templates
