 ### Phase 3: VM Agent Executable ✅
 - [x] Screen capture (scrap), input injection (enigo), auto-reconnect
 
+### Phase 3.6: System Service Installation ✅
+
+#### CLI Subcommands
+- [x] `agent/src/cli.rs` — Subcommand-based CLI (`run`, `service install/uninstall/start/stop/status/restart`)
+- [x] `agent/src/config.rs` — Renamed `AgentConfig` → `RunOptions`, added `Clone`, `to_service_args()`, hidden `--windows-service` flag
+
+#### Service Management (Linux systemd)
+- [x] `agent/src/service.rs` — systemd unit file generation with proper `ExecStart`, restart policy, env capture
+- [x] Auto-detects display environment variables (DISPLAY, WAYLAND_DISPLAY, XDG_RUNTIME_DIR, DBUS_SESSION_BUS_ADDRESS)
+- [x] `systemctl enable --now` on install, `daemon-reload` after changes
+- [x] Configurable user (`--user`), working directory (`--working-directory`), log file (`--log-file`)
+
+#### Service Management (Windows)
+- [x] `agent/src/service.rs` — Windows Service registration via `sc.exe` (create, start, stop, delete, query)
+- [x] Auto-start on boot, failure recovery (restart after 5s, reset after 1 day)
+- [x] `agent/src/main.rs` — Full Windows Service runtime via `windows-service` crate (SCM dispatcher, service control handler, SERVICE_RUNNING/STOPPED state reporting)
+
+#### Graceful Shutdown
+- [x] `tokio::signal::ctrl_c()` handler in foreground mode
+- [x] `tokio::sync::watch` shutdown channel propagated through reconnect loop
+- [x] WebSocket close frame sent on shutdown
+- [x] Windows SCM STOP/SHUTDOWN events trigger clean shutdown
+- [x] Reconnect loop checks shutdown before attempting reconnection
+
+#### Dependencies
+- [x] `agent/Cargo.toml` — `windows-service 0.7` (cfg windows), `clap` env feature, `base64 0.22`
