   - Search by error message or stack trace
   - Update issue status (resolve, ignore)
   - Add comments to issues

+### SSH Server Access
+
+Claude Code can execute commands on the production server via SSH:
+
+```bash
+# Basic command execution
+ssh root@projectium.com "command here"
+
+# Examples:
+ssh root@projectium.com "systemctl status logstash"
+ssh root@projectium.com "pm2 list"
+ssh root@projectium.com "tail -50 /var/www/flyer-crawler.projectium.com/logs/app.log"
+```
+
+**Use cases:**
+
+- Managing Logstash, PM2, NGINX, Redis services
+- Viewing server logs
+- Deploying configuration changes
+- Checking service status
+
+**Important:** SSH access requires the host machine to have SSH keys configured for `root@projectium.com`.
