 ### curl Usage
 When using curl commands, always set a timeout to 5 seconds:
-```bash
-curl --max-time 5 <url>
-# or
-curl -m 5 <url>

+ ### DNS Management
+
+ #### Create DNS Record via Cloudflare API
+ ```bash
+ # Get zone ID for domain
+ ZONE_ID=$(curl -s -X GET "https://api.cloudflare.com/client/v4/zones?name=symbiotrip.com" \
+   -H "Authorization: Bearer <CLOUDFLARE_API_TOKEN>" \
+   -H "Content-Type: application/json" | jq -r '.result[0].id')
+
+ # Create A record
+ curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/dns_records" \
+   -H "Authorization: Bearer <CLOUDFLARE_API_TOKEN>" \
+   -H "Content-Type: application/json" \
+   --data '{"type":"A","name":"<subdomain>","content":"<IP_ADDRESS>","ttl":1,"proxied":true}'
+ ```
+ **Common DNS Issues:**
+ - Local DNS caching: Add entry to `/etc/hosts` temporarily for testing
+ - Use Cloudflare's proxy IPs directly if DNS propagation is slow
+
 8. **Process Improvement**
-   - After successful deployment, propose 3 suggestions to add to agents.md that would help with future deployments:
-     1. [Specific pattern or configuration approach discovered]
-     2. [Common pitfall to avoid]
-     3. [Useful command or tool discovered]
+   - After successful deployment, propose 3 new tools to add to agents.md.

-1. **Borg Backup Server**
-   - Set up a dedicated Borg backup server for automated backups
-   - Configure backup schedules for critical systems
-   - Implement retention policies and pruning rules
+# List systemd services from new config
+ls /nix/store/<path>-nixos-system-<system>/etc/systemd/system/*.service
 
-2. **Secrets Management with sops-nix**
-   - Implement sops-nix for secrets management
-   - Move all hardcoded secrets from server configs into sops-nix
-   - Set up encryption keys and key rotation policies
-   - Document the secrets management workflow
