Next-generation IDE combining AI-powered development with semantic code understanding through knowledge graphs

Created by Jim McKenney with AEON AI Personal Agent

OpenSPG (Open Semantic Programming Graph) is a revolutionary web-based IDE that merges AI-assisted development with knowledge graph technology. It's not just a code editor—it's an intelligent development companion that understands your code semantically and helps you build better software faster.

Three Pillars:

1. 🤖 AI-First Development - Multi-agent BMAD workflow automates requirements → architecture → code
2. 🧠 Semantic Understanding - Knowledge graphs capture code relationships and domain knowledge
3. ⚡ Modern Developer Experience - VS Code-quality editing with real-time AI assistance

Multi-Agent BMAD Workflow:

• Business Analyst Agent - Analyzes requirements, generates user stories & acceptance criteria
• Method Designer Agent - Designs technical approach, selects technologies & patterns
• Architect Agent - Creates system architecture, API contracts, database schemas
• Developer Agent - Generates production-ready code, tests, and documentation

AI Chat Assistant:

• Context-aware code assistance
• Persistent conversation history
• Multi-model support (GPT-4, Claude 3.5, Gemini, etc.)
• Integrated with Monaco Editor

Intelligent Code Suggestions:

• Real-time code analysis
• Refactoring recommendations
• Performance optimizations
• Bug detection and fixes

Monaco Editor Integration:

• Full VS Code editing experience with IntelliSense
• Syntax highlighting for 12+ languages
• Multi-file tabs with overflow handling

OpenSPG implements the Business-Method-Architecture-Development workflow using AI agents:

Business Analyst Agent analyzes requirements and produces:

• User stories with personas
• Acceptance criteria
• Success metrics
• Risk assessment

Method Designer Agent creates technical approach:

• Technology stack selection
• Design patterns
• Implementation steps
• Performance considerations

Architect Agent designs system structure:

• Component architecture
• API contracts
• Database schemas
• Deployment diagrams

Developer Agent generates implementation:

• Production-ready code
• Unit tests
• Integration tests
• Documentation

All orchestrated through the Taskmaster system with progress tracking.

# Run all tests
pnpm test

# Run specific package tests
pnpm test --filter=@opencode/openrouter-sdk

# Run with coverage
pnpm test -- --coverage

# Watch mode
pnpm test -- --watch

# Development
pnpm dev              # Start all services in dev mode
pnpm build            # Build all packages

pnpm typecheck        # TypeScript type checking
pnpm lint             # Lint code (ESLint)
pnpm format           # Format code (Prettier)

# Docker
docker-compose up        # Start all containers
docker-compose down      # Stop all containers
docker-compose logs -f   # Follow logs
docker-compose restart   # Restart services

# Taskmaster CLI
