- "What customer touchpoints?" → Email, notifications
Generated:
- ecommerce-orchestrator
- order-processor (subagent)
- inventory-checker (subagent)
- refund-manager (subagent)
- Commands: /process-order, /check-inventory
Integration: Leverages existing task-manager, workflow-orchestrator
Existing: Dev tools (openagent, opencoder, build-agent, tester)
Command: /build-context-system "Add documentation generation"
Flow:
- Detects existing project
- User chooses: "Extend existing"
- Domain type: Hybrid (dev + content)
- Reuses: openagent, opencoder, documentation
- Adds: doc-orchestrator, api-doc-generator
- Result: Unified system with dev + docs

All generated systems implement proven patterns:
- +20% routing accuracy (LLM-based decisions with @ symbol routing)
- +25% consistency (XML structure with optimal component ordering)
- 80% context efficiency (3-level context allocation)
- +17% overall performance (position-sensitive component sequencing)
The system detects and integrates with existing agents:
Development Agents:
openagent- Universal agent for questions and tasksopencoder- Code analysis, file operationsbuild-agent- Build validation, type checkingtester- Test authoring, TDDreviewer- Code review, quality assurancecoder-agent- Code generationdocumentation- Documentation authoring
Business Agents:
task-manager- Task tracking, project managementworkflow-orchestrator- Workflow coordinationimage-specialist- Image generation/editing
Integration Strategy:
- Reuses existing agents where applicable
- Creates new agents only for gaps
- Builds unified orchestrator routing to both
- Merges context files intelligently
- ✅ Keeps all existing files
- ✅ Adds new capabilities
- ✅ Creates unified orchestrator
- ✅ Integrates new with existing agents
- Best for: Adding features to active projects
- ✅ Keeps existing system intact
- ✅ Creates new system in separate namespace
- ✅ Both systems coexist
- Best for: Multi-domain projects
⚠️ Backs up to.opencode.backup.{timestamp}/⚠️ Creates fresh system⚠️ Use with caution- Best for: Complete redesign
Generated systems score 8+/10 on:
Agent Quality:
- ✅ Optimal component ordering (context→role→task→instructions)
- ✅ Hierarchical context structure
- ✅ @ symbol routing with context levels
- ✅ Clear workflow stages with checkpoints
- ✅ Validation gates (pre_flight and post_flight)

-
Be specific about use cases
- Good: "Process customer orders from multiple channels"
- Bad: "Do stuff with orders"
-
Identify dependencies
- "Inventory check must happen before order processing"
-
Choose appropriate merge strategy
- Extending? Choose "Extend existing"
- New domain? Choose "Create separate"
-
Customize after generation
- Add domain-specific knowledge to context files
- Refine workflows based on real usage
- Add examples to improve agent performance
Fresh Build:
/build-context-system "Your domain name"Extend Existing:
/build-context-system "Add new capability"
# → Detects existing
# → Choose "Extend existing"
# → Integrates with current systemMulti-Domain:
/build-context-system "Client B project"
# → Detects existing Client A
# → Choose "Create separate"
# → Both systems coexist- Test orchestrator with simple request
- Test each subagent independently
- Verify context files load correctly
- Run workflows end-to-end
- Test custom commands
- Validate error handling
- Test edge cases
- Multi-agent coordination
- Context loading verification
- Routing logic validation
- Validation gates functionality
- Performance measurement
Issue: System overwrites existing files
Solution: Stage 0 should detect existing project and offer merge options. If not working, check project detection logic.
Issue: Questions don't match my domain
Solution: Stage 2.5 should detect domain type. Verify domain classification logic.
Issue: Doesn't integrate with existing agents
Solution: Check that existing agents are in .opencode/agent/ or .opencode/agent/subagents/
Issue: Generated agents don't route correctly
Solution: Verify @ symbol usage and context level specifications in agent files
After initial generation, you can:
- Add new agents manually
- Extend existing workflows
- Create additional commands
- Add more context files
Modify templates in .opencode/context/system-builder-templates/ to customize generation patterns.
Study generated orchestrators to understand integration patterns for your own agents.
Time: 10-15 minutes from start to production-ready system
Quality: All components score 8+/10
Safety: No data loss, backup before replace
Integration: Leverages existing agents, no duplication
Adaptability: Works for any domain (dev or non-dev)
