# deskctl
Desktop control CLI for AI agents on Linux X11.
## Install
```bash
cargo install deskctl
```
Build a Linux binary with Docker:
```bash
docker compose -f docker/docker-compose.yml run --rm build
```
This writes `dist/deskctl-linux-x86_64`.
Copy it to an SSH machine where `scp` is unavailable:
```bash
ssh -p 443 deskctl@ssh.agentcomputer.ai 'cat > ~/deskctl && chmod +x ~/deskctl' < dist/deskctl-linux-x86_64
```
Run it on an X11 session:
```bash
DISPLAY=:1 XDG_SESSION_TYPE=x11 ~/deskctl --json snapshot --annotate
```
Local source build requirements:
```bash
cargo build
```
At the moment there are no extra native build dependencies beyond a Rust toolchain.
## Quick Start
```bash
# See the desktop
deskctl snapshot
# Click a window
deskctl click @w1
# Type text
deskctl type "hello world"
# Focus by name
deskctl focus "firefox"
```
## Architecture
Client-daemon architecture over Unix sockets (NDJSON wire protocol).
The daemon starts automatically on first command and keeps the X11 connection alive for fast repeated calls.
## Runtime Requirements
- Linux with X11 session
- Rust 1.75+ (for build)
The binary itself only links the standard glibc runtime on Linux (`libc`, `libm`, `libgcc_s`).
For deskctl to be fully functional on a fresh VM you still need:
- an X11 server and an active `DISPLAY`
- `XDG_SESSION_TYPE=x11` or an equivalent X11 session environment
- a window manager or desktop environment that exposes standard EWMH properties such as `_NET_CLIENT_LIST_STACKING` and `_NET_ACTIVE_WINDOW`
- an X server with the extensions needed for input simulation and screen metadata, which is standard on normal desktop X11 setups
## Wayland Support
Coming soon. The trait-based backend design means adding Hyprland/Wayland support is a single trait implementation with zero refactoring of the core which is good.
