feat: refactor 30+ skills to Anthropic progressive disclosure pattern

- All SKILL.md files now <500 lines (avg reduction 69%)
- Detailed content extracted to references/ subdirectories
- Frontmatter standardised: only name + description (Anthropic standard)
- New skills: brand-guidelines, spec-coauthor, report-templates, skill-creator
- Design skills: anti-slop guidelines, premium-proposals reference
- Removed non-standard frontmatter fields (triggers, version, author, category)

Plugins affected: infraestrutura, marketing, dev-tools, crm-ops, gestao,
core-tools, negocio, perfex-dev, wordpress, design-media

+# PBS Avancado - Funcionalidades e Troubleshooting
+
+## Monitoring e Maintenance
+
+### Verificar Deduplicacao
+```bash
+# Ver estatisticas datastore
+proxmox-backup-manager datastore status main-store
+
+# Ratio deduplicacao (tipico 1.3-2.5x)
+```
+
+### Garbage Collection
+```bash
+# Liberar espaco de backups removidos (retention)
+proxmox-backup-manager garbage-collection start main-store
+
+# Agendar GC semanal (Domingo 02:00)
+# Via Web UI: Datastore -> main-store -> Prune & GC
+```
+
+### Verificar Disk Usage
+```bash
+df -h /mnt/pbs-datastore
+
+# ZFS
+zfs list -o name,used,available,refer rpool/pbs-datastore
+```
+
+### Alertas Email
+```bash
+# Configurar notificacoes
+# Via Web UI: Configuration -> Notifications
+# SMTP server: mail.descomplicar.pt
+# Alertas: disk usage >80%, backup failures
+```
+
+## PBS Advanced Features
+
+### Verification Jobs
+```bash
+# Verificar integridade backups
+proxmox-backup-manager verify-job create verify-main \
+  --store main-store \
+  --schedule "0 4 * * 0"  # Domingo 04:00
+```
+
+### Namespace Organization
+```bash
+# Organizar backups por tipo
+proxmox-backup-manager namespace create main-store/production
+proxmox-backup-manager namespace create main-store/testing
+proxmox-backup-manager namespace create main-store/archived
+```
+
+### Tape Backup (futuro)
+- PBS suporta LTO tape
+- Para compliance de longo prazo
+- Cold storage
+
+## Troubleshooting
+
+### Backup failing: "no space"
+```bash
+# Verificar disk usage
+df -h /mnt/pbs-datastore
+
+# Run GC manual
+proxmox-backup-manager garbage-collection start main-store
+
+# Ajustar retention (reduzir keeps)
+proxmox-backup-manager datastore update main-store --keep-daily 5
+```
+
+### Remote sync not working
+```bash
+# Verificar conectividade
+ping <remote-pbs-ip>
+
+# Testar autenticacao
+curl -k https://<remote-pbs-ip>:8007/api2/json/access/ticket \
+  -d "username=pve-backup@pbs&password=<password>"
+
+# Logs
+journalctl -u proxmox-backup -f
+```
+
+### Dedup ratio baixo (<1.2x)
+```bash
+# Verificar se VMs tem dados compressiveis
+# VMs com random data (encrypted) nao deduplica bem
+
+# Verificar chunk size (padrao 4MB adequado)
+proxmox-backup-manager datastore show main-store
+```
+
+## Estrategia 3-2-1 Backup
+
+**Implementacao para Cluster Descomplicar:**
+
+**3 copias:**
+1. **Original:** VMs em Node A (producao)
+2. **Backup primario:** PBS Node B (16TB HDD)
+3. **Backup secundario:** PBS Node A remote sync (12TB HDD)
+
+**2 medias diferentes:**
+1. NVMe (VMs producao)
+2. HDD Enterprise (PBS datastores)
+
+**1 off-site:**
+- **Opcao A:** Hetzner Storage Box (rsync daily)
+- **Opcao B:** S3-compatible (Wasabi/Backblaze)
+- **Opcao C:** PBS em VPS externo
+
+**RPO:** 1h (backups hourly se critical)
+**RTO:** 2-4h (restore + validacao)
+
+## Metricas Esperadas
+
+| Metrica | Valor tipico |
+|---------|-------------|
+| Dedup ratio | 1.5-2.5x |
+| Compression ratio | 1.3-1.8x |
+| Backup speed | 100-300 MB/s |
+| Restore RTO | 2-4h (para VM 100GB) |
