Jordan Ramos d3dc899b30 docs(infrastructure): correct VM/template counts and clarify resource types 
Update infrastructure documentation across all files to accurately distinguish
between active VMs (8), templates (2), and LXC containers (4). Previously,
VM templates 104 (ubuntu-dev) and 107 (ubuntu-docker) were incorrectly counted
as active VMs, inflating the total VM count to 10.

Changes:
- CLAUDE.md: Update Quick Reference and Infrastructure Overview sections
- CLAUDE_STATUS.md: Add dedicated VM Templates section with explanatory note
- INDEX.md: Separate templates from active VMs in infrastructure inventory
- README.md: Add VM Templates section distinguishing from active VMs
- Claude_UPDATES.md: Update infrastructure counts in Quick Reference tables
- services/README.md: Correct footer infrastructure counts
- sub-agents/*.md: Update infrastructure context in all agent prompts

This ensures accurate resource tracking and clarifies that templates are
immutable base images for cloning, not running workloads.

Homelab Infrastructure Status

Last Updated: 2025-12-07 12:00:40 Export Reference: disaster-recovery/homelab-export-20251207-120040

Current Infrastructure Snapshot

Proxmox Environment

  • Node: serviceslab

  • Management IP: 192.168.2.200
  • Architecture: Single-node cluster
  • Total Resources: 8 VMs, 2 Templates, 4 LXC Containers

Virtual Machines (QEMU/KVM) - 8 VMs

VM ID Name IP Address Status Purpose

Recent Changes:

  • Added CT 112 (twingate-connector) for zero-trust network security
  • Added CT 113 (n8n) for workflow automation
  • Removed CT 112 (Anytype) - replaced by n8n

Storage Architecture

Storage Pool Type Total Used % Used 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 PBS - - 27.43% Automated backup repository

Capacity Notes:

  • PBS-Backups utilization increased to 27.43% (healthy retention)
  • Vault utilization decreased to 10.88% (space optimization)
  • local storage at 15.13% (system overhead normal)

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

  • 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
  • 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
  • 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)
  • 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)
  • 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
  • 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.
