+## CRITICAL: Server Access Model
+
+**Claude Code has READ-ONLY access to production/test servers.**
+
+The `claude-win10` user cannot execute write operations (PM2 restart, systemctl, file modifications) directly on servers. The devops subagent must **provide commands for the user to execute**, not attempt to run them via SSH.
+
+### Command Delegation Workflow
+
+When troubleshooting or making changes to production/test servers:
+
+| Phase    | Actor  | Action                                                      |
+| -------- | ------ | ----------------------------------------------------------- |
+| Diagnose | Claude | Provide read-only diagnostic commands                       |
+| Report   | User   | Execute commands, share output with Claude                  |
+| Analyze  | Claude | Interpret results, identify root cause                      |
+| Fix      | Claude | Provide 1-3 fix commands (never more, errors may cascade)   |
+| Execute  | User   | Run fix commands, report results                            |
+| Verify   | Claude | Provide verification commands to confirm success            |
+| Document | Claude | Update relevant documentation with findings and resolutions |
+
+### Example: PM2 Process Issue
+
+Step 1 - Diagnostic Commands (Claude provides, user runs):
+
+```bash
+# Check PM2 process status
+pm2 list
+
+# View recent error logs
+pm2 logs flyer-crawler-api --err --lines 50
+
+# Check system resources
+free -h
+df -h /var/www
+```
+
+Step 2 - User reports output to Claude
+
+Step 3 - Fix Commands (Claude provides 1-3 at a time):
+
+```bash
+# Restart the failing process
+pm2 restart flyer-crawler-api
+```
+
+Step 4 - User executes and reports result
+
+Step 5 - Verification Commands:
+
+```bash
+# Confirm process is running
+pm2 list
+
+# Test API health
+curl -s https://flyer-crawler.projectium.com/api/health/ready | jq .
+```
+
+### What NOT to Do
+
+```bash
+# WRONG - Claude cannot execute this directly
+ssh root@projectium.com "pm2 restart all"
+
+# WRONG - Providing too many commands at once
+pm2 stop all && rm -rf node_modules && npm install && pm2 start all
+
+# WRONG - Assuming commands succeeded without user confirmation
+```
