# Port Management System
## When to use this
Load this skill whenever you need to:
- Add a new service that binds to a TCP port
- Diagnose port conflicts ("port already in use", "port is already allocated")
- Audit which services are running and on which ports
- Lock a port to a specific user/process via iptables
- Recover from a port collision
## Architecture
```
port-manager status # List all live ports
port-manager verify # Check locked ports have correct owners
