## Architecture Patterns

### Monitoring & Observability (NEW)
The infrastructure now implements a comprehensive monitoring stack following industry best practices:

- **Metrics Collection**: Prometheus scraping Proxmox metrics via PVE Exporter
- **Visualization**: Grafana providing real-time dashboards and alerting
- **Isolation**: Dedicated VM for monitoring services (fault isolation)
- **Integration**: Ready for AlertManager, additional exporters, and integrations

**Design Decision**: VM-based deployment provides kernel-level isolation and prevents resource contention with critical infrastructure services.

### Zero-Trust Security (NEW)
Implementation of zero-trust network access principles:

- **Twingate Connector**: Lightweight connector providing secure access without VPNs
- **Container Deployment**: LXC container for minimal resource overhead
- **Network Segmentation**: Secure access to homelab from external networks

**Design Decision**: LXC container chosen for quick provisioning and low resource consumption.

### Automation-First Approach
Workflow automation and infrastructure orchestration:

- **n8n Platform**: Visual workflow builder for API integrations
- **Scheduled Tasks**: Automated backup checks, monitoring alerts, reports
- **Integration Hub**: Connects monitoring, documentation, and operational tools

**Design Decision**: PostgreSQL backend ensures data persistence and supports complex workflows.

### Tiered Application Architecture
Classic three-tier design for production-like environments:

- **Presentation Tier**: Paired web servers (109, 110) behind load balancer
- **Business Logic**: Application processing on web tier
- **Data Tier**: Dedicated database server (111) with backup strategy

**Design Decision**: Separation of concerns, scalability testing, high availability patterns.

### Selective Containerization Strategy
Hybrid approach balancing performance and resource efficiency:

- **LXC Containers**: Stateless services (nginx, netbox, twingate, n8n)
- **Full VMs**: Complex applications, kernel dependencies, heavy workloads
- **Rationale**: LXC for ~10x lower overhead, VMs for isolation and compatibility

## Current Initiative: Sub-Agent Architecture Optimization (2025-12-07)

### Goal
Improve the quality and effectiveness of all sub-agent prompt definitions to match best practices identified through comprehensive Opus-powered prompt engineering analysis. Target: bring all sub-agents to the quality standard established by librarian.md (~120-340 lines with comprehensive examples, safety protocols, and decision frameworks).

### Phase
✅ COMPLETED - All sub-agent improvements and validations finished

### Progress Checklist
- [x] Prompt engineering analysis completed (Opus model)
  - Analyzed CLAUDE.md and all 4 sub-agent files
  - Identified 5 critical issues, 12 high-impact improvements
  - Generated comprehensive improvement recommendations
- [x] scribe.md improved (29→340 lines)
  - Added 6 usage examples (4 positive, 2 negative redirects)
  - Implemented comprehensive responsibilities section
  - Added 3 complete ASCII diagram templates
  - Included safety protocols and decision frameworks
  - Quality now matches librarian.md standard
- [x] backend-builder.md improved (40→291 lines)
  - Added 6 usage examples with clear boundaries
  - Expanded core responsibilities with Ansible, Terraform, Docker Compose, Python, Shell
  - Added technology stack table and validation rules table
  - Included safety protocols for secrets and destructive operations
  - Added handoff protocol for lab-operator deployment
  - Defined clear boundaries (CREATES code, does NOT deploy)
- [x] lab-operator.md improved (37→193 lines)
  - Added 6 usage examples with role clarity
  - Expanded domain expertise with specific commands
  - Added command style guide (5-step pattern)
  - Included safety protocols and decision-making framework
  - Added error handling and escalation guidelines
  - Defined clear boundaries (DEPLOYS/OPERATES, does NOT create IaC)
- [x] CLAUDE.md structural fixes
  - Moved YAML frontmatter to line 1 (was at line 89)
  - Fixed trailing pipe character on line 87
  - Completed incomplete sentence about backup strategy
  - Completed incomplete sentence about storage growth
  - Removed redundant "Key Services" reference
  - Expanded status file template with actual structure and recovery instructions
- [x] Final validation and testing
  - librarian: ✅ Git status check successful, clear output format
  - scribe: ✅ File reading functional (note: reported encoding issue, likely false positive)
  - backend-builder: ✅ YAML validation successful, proper syntax checking
  - lab-operator: ✅ Directory listing successful, proper command execution
  - All agents demonstrate improved structure and clarity

### Context
**Why It Matters**: Well-designed sub-agent prompts improve task routing accuracy, execution quality, error reduction, and maintainability. The librarian.md agent (143 lines) sets the quality standard; scribe was severely underdeveloped at 29 lines before improvement.

**Next Steps**: Improve backend-builder.md and lab-operator.md using scribe.md as quality template.
