## 📋 Nächste Schritte

### Sofort (heute)
- [ ] Session-Logs aus dieser Woche reviewen
- [ ] Skill-Proposals durchsehen

### Diese Woche
- [ ] \`/vault-janitor distill\` ausführen (falls > 5 neue Logs)
- [ ] Projekt-MEMORYs synchronisieren (\`vault-sync\`)

### Diesen Monat
- [ ] Anti-Patterns aktualisieren (neue Fehler dokumentieren)
- [ ] Skill-Usage-Matrix analysieren (welche Skills werden oft genutzt?)
- [ ] Obsolete Skills identifizieren (welche Skills werden nie genutzt?)
