• 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

🚀 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

node index.js clean --temp-only

# Force optimization
npm run optimize

Performance Issues:

# Get optimization report
# Use get_optimization_report tool in Claude

# Check cache statistics
# Use get_kg_statistics tool with includeDetails: true

# Force cache refresh
node index.js clean --temp-only

Debug Mode

# Enable comprehensive debugging
export LOG_LEVEL=debug
export NODE_ENV=development
node index.js start --debug

📈 Performance

• Response Time: <100ms for simple queries, <5s for complex analysis
• Memory Usage: ~50MB baseline, scales with codebase size
• Cache Hit Rate: >90% for repeated operations
• Concurrent Requests: Supports 100+ simultaneous tool calls
• Database Size: ~1MB per 10K lines of analyzed code
