Context-Aware System Builder

Build complete, production-ready AI systems tailored to your domain in minutes.

Overview

The Context-Aware System Builder is a sophisticated meta-system that generates complete .opencode folder architectures customized to your specific domain, use cases, and requirements. It combines prompt-enhancer techniques with comprehensive context-aware system design principles to create production-ready AI systems.

What It Does

Transforms your requirements into a complete AI system with:

✅ Main Orchestrator Agent - Intelligent coordinator that analyzes requests and routes to specialists
✅ Specialized Subagents - Domain-specific experts (3-7 agents)
✅ Organized Context Files - Modular knowledge base (domain/processes/standards/templates)
✅ Workflow Definitions - Reusable process patterns
✅ Custom Slash Commands - User-friendly interfaces
✅ Complete Documentation - README, architecture guide, testing checklist, quick start

Context Flow

Level 1: Complete Isolation (80% of generation tasks)

• Used for: domain-analyzer, command-creator
• Context: Task specification only
• Efficiency: 80% reduction in overhead

Level 2: Filtered Context (20% of generation tasks)

• Used for: agent-generator, context-organizer, workflow-designer
• Context: Architecture plan + domain analysis + relevant specs
• Efficiency: 60% reduction in overhead

Level 3: Windowed Context (Never used in generation)

• System generation is stateless

4. Run workflows end-to-end
5. Test custom commands
6. Validate error handling
7. Test edge cases

Integration Testing

1. Multi-agent coordination
2. Context loading verification
3. Routing logic validation
4. Validation gates functionality
5. Performance measurement

Quality Validation

• Agent quality scores
• Context organization scores
• Workflow completeness scores
• Documentation clarity scores
• Overall system score (must be 8+/10)

Customization

After generation, customize:

1. Context Files: Add domain-specific knowledge
2. Workflows: Adjust based on real usage
3. Validation Criteria: Refine quality standards
4. Agent Prompts: Add examples and edge cases
5. Commands: Create additional slash commands

Best Practices

For Interviews

• Be specific about use cases
• Provide concrete examples
• Identify dependencies between tasks
• Think about edge cases
• Consider integration needs

For Generated Systems

• Start with simple use cases
• Test thoroughly before production
• Customize context with real knowledge
• Monitor performance and iterate
• Document learnings and patterns

For Context Management

• Keep files focused (50-200 lines)
• Use clear, descriptive names
• Avoid duplication
• Document dependencies
• Include concrete examples

For Performance

• Use Level 1 context for 80% of tasks
• Only use Level 2 when domain knowledge needed
• Rarely use Level 3 (complex coordination only)
• Load context selectively
• Monitor efficiency metrics

Troubleshooting

Common Issues

Issue: Interview doesn't capture all requirements
Solution: You can revise before generation or customize after

Issue: Generated agents don't route correctly
Solution: Check @ symbol usage and context level specifications in agent files

Issue: Context files are too large
Solution: Split into smaller, focused files (target 50-200 lines)

Issue: Workflows are unclear
Solution: Add more detailed steps and examples in workflow files

Issue: Commands don't work as expected
Solution: Verify agent routing in command frontmatter
