feat(agents): optimize sub-agent architecture with comprehensive prompt engineering

Browse Source 
This commit implements a comprehensive optimization of all sub-agent prompt
definitions based on Opus-powered prompt engineering analysis. All agents now
match the quality standard established by librarian.md.

Agent Improvements:
- scribe.md: 29→340 lines (11.7x expansion)
  * Added 6 usage examples with role clarity
  * Implemented comprehensive responsibilities section
  * Added 3 complete ASCII diagram templates
  * Included safety protocols and decision frameworks

- backend-builder.md: 40→291 lines (7.3x expansion)
  * Added 6 usage examples with clear boundaries
  * Expanded core responsibilities (Ansible, Terraform, Docker, Python, Shell)
  * Added technology stack and validation rules tables
  * Included handoff protocol for lab-operator deployment
  * Defined clear boundaries (CREATES code, does NOT deploy)

- lab-operator.md: 37→193 lines (5.2x expansion)
  * 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
  * Defined clear boundaries (DEPLOYS/OPERATES, does NOT create IaC)

- librarian.md: Minor formatting improvements

CLAUDE.md Fixes:
- Moved YAML frontmatter to line 1 (was incorrectly at line 89)
- Fixed trailing pipe character
- Completed incomplete sentences about backup strategy and storage growth
- Removed redundant information
- Expanded status file template with recovery instructions

Files Added:
- Claude_UPDATES.md: Comprehensive prompt engineering analysis report
- monitoring/pve-exporter/pve.yml: PVE monitoring configuration

Impact:
- Total agent documentation: 249→967 lines (288% increase)
- Usage examples: 6→24 total (400% increase)
- All agents now have comprehensive safety protocols
- Clear role boundaries prevent agent overlap
- Validation testing confirms all agents functional

### Agent Collaboration Patterns
**Documentation Workflow:**
1. `backend-builder` or `lab-operator` creates/modifies infrastructure
2. `scribe` updates documentation
3. `librarian` commits all changes
**Infrastructure Deployment:**
1. `backend-builder` writes IaC (Ansible/Terraform/Compose)
2. `lab-operator` deploys to Proxmox/Docker
3. `scribe` documents deployment
4. `librarian` commits configuration
## Infrastructure Overview
### Proxmox Environment
- **Platform**: Proxmox Virtual Environment 8.3.3
- **Architecture Pattern**: Services/Development Laboratory
- **Primary Node**: `serviceslab` (single-node cluster)
- **Deployment Model**: Hybrid VM + LXC container approach
**For detailed, current infrastructure inventory, see:**
- **Live Status**: `CLAUDE_STATUS.md` (most current)
- **Service Details**: `services/README.md`
- **Complete Index**: `INDEX.md`
### Key Services & Virtual Machines (QEMU/KVM)
**Quick Summary:**
- **VMs**: 10 total (IDs: 100, 101, 104-111)
- **LXC Containers**: 4 total (IDs: 102, 103, 112, 113)
- **Storage Pools**: local, local-lvm, Vault (ZFS), PBS-Backups, iso-share
- **Monitoring**: VM 101 at 192.168.2.114 (Grafana/Prometheus/PVE Exporter)
The infrastructure employs full VMs for services requiring kernel-level isolation, complex dependencies, or heavyweight applications:
| VM ID | Name | Purpose | Notes |
|-------|------|---------|-------|
| 100 | docker-hub | Container registry/Docker hub mirror | Local container image caching |
| 101 | monitoring-docker | Monitoring stack | Grafana/Prometheus/PVE Exporter at 192.168.2.114 |
| 104 | ubuntu-dev | Ubuntu development environment | Additional dev workstation |
| 105 | dev | Development environment | General-purpose development workstation |
| 106 | Ansible-Control | Automation control node | IaC orchestration, configuration management |
| 107 | ubuntu-docker | Ubuntu Docker host | Docker-focused environment |
| 108 | CML | Cisco Modeling Labs | Network simulation/testing environment |
| 109 | web-server-01 | Web application server | Production-like web tier (clustered) |
| 110 | web-server-02 | Web application server | Load-balanced pair with web-server-01 |
| 111 | db-server-01 | Database server | Backend data tier |
### Containers (LXC)
Lightweight services leveraging LXC for reduced overhead and faster provisioning:
| CT ID | Name | Purpose | Notes |
|-------|------|---------|-------|
| 102 | nginx | Reverse proxy/load balancer | Front-end traffic management (NPM) |
| 103 | netbox | Network documentation/IPAM | Infrastructure source of truth |
| 112 | twingate-connector | Zero-trust network access | Secure remote access connector |
| 113 | n8n | Workflow automation | n8n.io platform at 192.168.2.107 |
### Storage Architecture
The storage layout demonstrates a well-organized approach to data separation:
| Storage Pool | Type | Usage | Purpose |
|--------------|------|-------|---------|
| local | Directory | 15.13% | System files, ISOs, templates |
| local-lvm | LVM-Thin | 0.0% | VM disk images (thin provisioned) |
| Vault | NFS/Directory | 10.88% | Secure storage for sensitive data |
| PBS-Backups | Proxmox Backup Server | 27.43% | Automated backup repository |
| iso-share | NFS/CIFS | 1.4% | Installation media library |
| localnetwork | Network share | N/A | Shared resources across infrastructure |
**Note**: Infrastructure details change frequently. Always reference `CLAUDE_STATUS.md` for accurate counts, IPs, and status.
### Architecture Patterns & Design Decisions
**Tiered Application Architecture**: The infrastructure implements a classic three-tier design with dedicated web servers (109, 110), database server (111), and reverse proxy (102), suggesting this lab is used for practicing production-like deployments.
**Automation-First Approach**: The presence of Ansible-Control (106), GitLab (101), and NetBox (103) indicates a focus on Infrastructure as Code and proper documentation practices—rather civilized.

### Best Practices
1. **Backup Strategy**: With PBS-Backups at 21.6% utilization and excellent uptime (27-68 days), ensure regular backup schedules are maintained. Consider implementing the 3-2-1 rule if not already in place.
2. **Resource Management**: Monitor the local-lvm pool (currently 0.0%)—this appears to be reserved capacity. Ensure thin provisioning doesn't lead to overcommitment.
3. **Configuration Management**: Utilize the Ansible-Control node (106) for infrastructure changes. Avoid manual configuration drift.
4. **Documentation**: NetBox (103) should be the single source of truth for IP addressing, VLANs, and service inventory. Keep it updated.
5. **Version Control**: GitLab (101) should house all Infrastructure as Code, scripts, and configuration files from this repository.
6. **Load Balancing**: The paired web servers (109, 110) suggest HA testing—ensure nginx (102) is properly configured for failover.
### Access Patterns
- **Proxmox Web UI**: Primary management interface for VM/CT lifecycle operations
- **Ansible**: Automated configuration deployment and orchestration
- **GitLab**: CI/CD pipelines for infrastructure testing and deployment
- **Gitea**: CI/CD pipelines for infrastructure testing and deployment
- **NetBox**: Network documentation and IP address management
### Maintenance Considerations
- **Uptime**: Services showing 27-68 days uptime—schedule maintenance windows for kernel updates
- **Storage Growth**: PBS-Backups at 21.6% allows healthy retention; review backup policies quarterly
- **Capacity Planning**: Current utilization suggests comfortable headroom; monitor trends via Proxmox metrics
- **Uptime**: Track uptime metrics in disaster recovery exports for trend analysis
- **Storage Growth**: PBS-Backups at 27.43%, Vault at 10.88%, local at 15.13% (see CLAUDE_STATUS.md for current metrics)
- **Capacity Planning**: Current utilization suggests comfortable headroom; monitor trends via Proxmox metrics in monitoring-docker (101)
