## Real-World Example: Proxmox Skill

Based on the proxmox-auth skill in this repository:

### Extracted Knowledge

**From**: Proxmox VE cluster documentation + operational experience

**Structured as**:
1. **Authentication**: SSH access patterns, node IPs
2. **Architecture**: Cluster topology (2 nodes, resources)
3. **Operations**: Container/VM management commands
4. **Troubleshooting**: Common errors and fixes
5. **Networking**: Bridge configuration, IP management
6. **GPU Passthrough**: Special container configurations

**Result**: Comprehensive skill covering:
- Quick access to any node
- Container lifecycle management
- GPU-accelerated containers
- Network troubleshooting
- Backup procedures
- Common gotchas and solutions

## Extraction Scripts

### Extract from Runbooks

```bash
#!/bin/bash
# extract-from-runbook.sh - Convert runbook to skill

RUNBOOK_FILE="$1"
SKILL_NAME="$2"

if [ -z "$RUNBOOK_FILE" ] || [ -z "$SKILL_NAME" ]; then
    echo "Usage: $0 <runbook.md> <skill-name>"
    exit 1
fi

SKILL_DIR="skills/$SKILL_NAME"
mkdir -p "$SKILL_DIR"

# Extract sections from runbook
cat > "$SKILL_DIR/SKILL.md" << EOF
---
name: $SKILL_NAME
description: $(head -5 "$RUNBOOK_FILE" | grep -v "^#" | head -1 | xargs)
license: MIT
extracted-from: $RUNBOOK_FILE
---

# ${SKILL_NAME^}

$(cat "$RUNBOOK_FILE")

---

**Note**: This skill was auto-extracted from runbook documentation.
Review and refine before use.

#!/bin/bash
# docker-compose-to-skill.sh - Extract skill from docker-compose.yaml

COMPOSE_FILE="${1:-docker-compose.yaml}"
PROJECT_NAME=$(basename $(pwd))

SKILL_DIR="skills/docker-$PROJECT_NAME"
mkdir -p "$SKILL_DIR"

# Extract services

# Docker $PROJECT_NAME

Manage Docker Compose stack for $PROJECT_NAME.

## Services

$(yq eval '.services | to_entries | .[] | "### " + .key + "\n" + (.value.image // "custom") + "\n"' "$COMPOSE_FILE")

## Quick Start

\`\`\`bash
# Start all services
docker-compose up -d

# Check status
docker-compose ps

# View logs
docker-compose logs -f

# Stop all services
docker-compose down
\`\`\`

## Service Details

### Ports

$(yq eval '.services | to_entries | .[] | select(.value.ports) | "- **" + .key + "**: " + (.value.ports | join(", "))' "$COMPOSE_FILE")

### Volumes

$(yq eval '.services | to_entries | .[] | select(.value.volumes) | "- **" + .key + "**: " + (.value.volumes | join(", "))' "$COMPOSE_FILE")

## Configuration

See \`$COMPOSE_FILE\` for full configuration.

## Common Operations

### Restart Service

\`\`\`bash
docker-compose restart SERVICE_NAME
\`\`\`

### Update Service

\`\`\`bash
docker-compose pull SERVICE_NAME
docker-compose up -d SERVICE_NAME
\`\`\`

### View Service Logs

\`\`\`bash
docker-compose logs -f SERVICE_NAME
\`\`\`

## Troubleshooting

### Service Won't Start

1. Check logs: \`docker-compose logs SERVICE_NAME\`
2. Verify ports not in use: \`netstat -tulpn | grep PORT\`
3. Check disk space: \`df -h\`

### Network Issues

\`\`\`bash
# Recreate network
docker-compose down
docker network prune
docker-compose up -d
\`\`\`

# k8s-to-skill.sh - Extract skill from Kubernetes manifests

K8S_DIR="${1:-.}"
APP_NAME="${2:-$(basename $(pwd))}"

SKILL_DIR="skills/k8s-$APP_NAME"
mkdir -p "$SKILL_DIR"

# Kubernetes $APP_NAME

Manage Kubernetes resources for $APP_NAME.

## Resources

$(find "$K8S_DIR" -name "*.yaml" -o -name "*.yml" | while read file; do
    KIND=$(yq eval '.kind' "$file" 2>/dev/null)
    NAME=$(yq eval '.metadata.name' "$file" 2>/dev/null)
    echo "- **$KIND**: $NAME ($(basename $file))"
done)

## Deployment

### Apply All Resources

\`\`\`bash
kubectl apply -f $K8S_DIR/
\`\`\`

### Check Status

\`\`\`bash
# Pods
kubectl get pods -l app=$APP_NAME

# Services
kubectl get svc -l app=$APP_NAME

# Deployments
kubectl get deploy -l app=$APP_NAME
\`\`\`

## Common Operations

### Scale Deployment

\`\`\`bash
kubectl scale deployment $APP_NAME --replicas=3
\`\`\`

### Update Image

\`\`\`bash
kubectl set image deployment/$APP_NAME container=new-image:tag
\`\`\`

### View Logs

\`\`\`bash
kubectl logs -f deployment/$APP_NAME
\`\`\`

### Port Forward

\`\`\`bash
kubectl port-forward svc/$APP_NAME 8080:80
\`\`\`

## Troubleshooting

### Pod Not Starting

\`\`\`bash
# Check pod events
kubectl describe pod POD_NAME

# Check logs
kubectl logs POD_NAME

# Previous instance logs
kubectl logs POD_NAME --previous
\`\`\`

### Service Not Reachable

\`\`\`bash
# Check endpoints
kubectl get endpoints $APP_NAME

# Check service
kubectl describe svc $APP_NAME

# Test from another pod
kubectl run -it --rm debug --image=busybox --restart=Never -- wget -O- http://$APP_NAME

## Deployment Workflow

1. **Backup current state**
   ```bash
   ./backup.sh

## Best Practices

### ✅ DO

1. **Document assumptions** - What's required before operations
2. **Include verification** - How to verify each operation succeeded
3. **Add troubleshooting** - Common issues and fixes
4. **Show outputs** - Expected command outputs
5. **Link resources** - Related documentation and skills
6. **Version information** - Software versions, configurations
7. **Security notes** - Security implications of operations
8. **Update regularly** - Keep skills current with infrastructure

### ❌ DON'T

1. **Don't hardcode secrets** - Use placeholders or env vars
2. **Don't skip context** - Explain why, not just how
3. **Don't assume knowledge** - Explain terminology
4. **Don't omit edge cases** - Document special scenarios
5. **Don't forget cleanup** - Include teardown procedures
6. **Don't ignore dependencies** - Document prerequisites
7. **Don't skip testing** - Verify all commands work
8. **Don't leave TODO** - Complete all sections
