# 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
|
|
# Diagnose the environment first
|
|
deskctl doctor
|
|
|
|
# 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.
|
|
|
|
Source layout:
|
|
|
|
- `src/lib.rs` exposes the shared library target
|
|
- `src/main.rs` is the thin CLI wrapper
|
|
- `src/` contains production code and unit tests
|
|
- `tests/` contains Linux/X11 integration tests
|
|
- `tests/support/` contains shared integration helpers
|
|
|
|
## 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
|
|
|
|
If setup fails, run:
|
|
|
|
```bash
|
|
deskctl doctor
|
|
```
|
|
|
|
## Contract Notes
|
|
|
|
- `@wN` refs are short-lived handles assigned by `snapshot` and `list-windows`
|
|
- `--json` output includes a stable `window_id` for programmatic targeting within the current daemon session
|
|
- `list-windows` is a cheap read-only operation and does not capture or write a screenshot
|
|
|
|
## Support Boundary
|
|
|
|
`deskctl` supports Linux X11 in this phase. Wayland and Hyprland are explicitly out of scope for the current runtime contract.
|
|
|
|
## Workflow
|
|
|
|
Local validation uses the root `Makefile`:
|
|
|
|
```bash
|
|
make fmt-check
|
|
make lint
|
|
make test-unit
|
|
make test-integration
|
|
make site-format-check
|
|
make validate
|
|
```
|
|
|
|
`make validate` is the full repo-quality check and requires Linux with `xvfb-run` plus `pnpm --dir site install`.
|
|
|
|
The repository standardizes on `pre-commit` for fast commit-time checks:
|
|
|
|
```bash
|
|
pre-commit install
|
|
pre-commit run --all-files
|
|
```
