# Hyprland desktop bridge
|
||||
|
||||
Local stdio MCP server for Hyprland 0.56+, using `grim`, `hyprctl`, `ydotool`,
|
||||
`wtype`, and `xdotool`. Registered as `hyprland_desktop` in the Linux Codex config.
|
||||
The shared skill is `~/.agents/skills/hyprland-computer-use/SKILL.md`.
|
||||
|
||||
The server starts on demand as the logged-in user. It has no network listener,
|
||||
shell-command tool, or arbitrary file-write tool. It inherits the graphical session
|
||||
environment through the MCP config. The agent's normal sandbox remains enabled.
|
||||
Focus checks and coordinate validation reduce misdirected input but do not isolate
|
||||
apps or prevent desktop-wide keyboard shortcuts. Use one desktop task at a time.
|
||||
|
||||
The existing user `ydotool.service` owns a mode-0600 socket at
|
||||
`$XDG_RUNTIME_DIR/.ydotool_socket`. This machine already grants the active user access
|
||||
to `/dev/uinput` through its installed Steam input udev rule. No new root service,
|
||||
input-group membership, or system-wide permission rule was added.
|
||||
|
||||
## Maintenance
|
||||
|
||||
Inspect input service state with `systemctl --user status ydotool.service`.
|
||||
If input stops after system package changes, check `/dev/uinput` and its ACL before
|
||||
changing permissions. Stop input injection with `systemctl --user stop ydotool.service`;
|
||||
other programs using that shared service will also lose synthetic mouse input.
|
||||
To disable this MCP bridge, set `enabled = false` in its Codex config section and
|
||||
restart the client.
|
||||
|
||||
Dependencies are pinned in `requirements.lock`. Recreate the environment with:
|
||||
|
||||
```sh
|
||||
cd ~/.codex/bridges/hyprland-desktop
|
||||
uv venv .venv --python 3.13
|
||||
uv pip sync --python .venv/bin/python requirements.lock
|
||||
```
|
||||
|
||||
## Verification
|
||||
|
||||
These commands briefly operate a temporary test window on the live desktop.
|
||||
Keep local mouse and keyboard input idle during the run.
|
||||
|
||||
```sh
|
||||
.venv/bin/python test_desktop.py
|
||||
.venv/bin/python test_desktop.py --native
|
||||
```
|
||||
|
||||
The first tests XWayland with Tk; the second tests native Wayland with GTK 4.
|
||||
They exercise the MCP handshake and tool calls, Unicode text, selection shortcuts,
|
||||
clicks, wheel input, dragging, PNG capture, input validation, and the focus guard.
|
||||
The latest screenshot is `/tmp/hyprland-desktop-verified.png`.
|
||||
Test fixtures require the system Python Tk and PyGObject/GTK packages.

description: "Delegate desktop GUI and workstation control to a Codex subagent that acts as remote hands while Claude Code reads the screenshots. Use when a task needs to see or operate the local desktop: take a screenshot, check what is currently on screen, inspect or drive a native or Electron app window, read window/workspace/monitor state, launch a desktop program, or run a live-session workflow that a sandboxed shell cannot reach. Not for web pages (use the Chrome DevTools or Playwright MCP tools) and not for ordinary repo edits (use the delegate skill). Codex only: gpt-5.6-terra for narrow work, gpt-5.6-sol for complex or risky work; never gpt-5.6-luna, Luna aliases, or Claude models."

# Claude Code Computer Delegate
|
||||
|
||||
## The one thing to understand first
|
||||
|
||||
**Codex is the hands. Claude Code is the eyes.**
|
||||
|
||||
Verified on this machine: a `codex exec` subagent *cannot view image files*. Asked to
|
||||
screenshot the desktop and describe it, it replies `CANNOT VIEW IMAGES`. So never ask
|
||||
Codex "what does the screen look like" or "check whether the dialog appeared". It is
|
||||
blind.
|
||||
|
||||
The working division of labor:
|
||||
|
||||
| Step | Who | How |
|
||||
|---|---|---|
|
||||
| Capture screen, drive windows, launch apps, run live-session commands | Codex subagent | `grim`, `hyprctl`, `wtype` |
|
||||
| Interpret pixels: layout, colors, error text, "did it work" | Claude Code (you) | `Read` the PNG path Codex reports |
|
||||
| Decide the next action | Claude Code (you) | Send a follow-up brief |
|
||||
|
||||
Codex reasons only over **text**: `hyprctl -j clients` JSON, command output, exit codes,
|
||||
log files. Have it report those. Have it report *screenshot paths*, never screenshot
|
||||
*descriptions*.
|
||||
|
||||
## Use this skill when
|
||||
|
||||
- "What's on my screen right now", "take a screenshot", "look at my desktop"
|
||||
- Inspecting or operating a native/Electron/GTK/Qt app window
|
||||
- Reading window, workspace, or monitor layout state
|
||||
- Launching or focusing a desktop program
|
||||
- A command that must touch the live graphical session
|
||||
|
||||
## Do NOT use this skill when
|
||||
|
||||
- **Web page or web app work.** You have `chrome-devtools` and `playwright` MCP tools
|
||||
in-process. They give you the DOM, console, network, and snapshots you can actually
|
||||
see. Delegating browser work to a blind subagent is strictly worse. Use the MCP tools.
|
||||
- **Plain repo work** (reading code, edits, reviews) with no GUI involved. Use the
|
||||
`delegate` skill instead.
|
||||
- The task is a single command you can just run in Bash yourself. Do that.
|
||||
|
||||
## Hard model policy
|
||||
|
||||
- Provider `codex` only. Model must be `gpt-5.6-terra` or `gpt-5.6-sol`.
|
||||
- Never `gpt-5.6-luna`, `luna`, aliases, `latest`, fallbacks, Claude models, or pre-5.6
|
||||
Codex models.
|
||||
- If the user names a model outside this set, stop and report the conflict. Do not
|
||||
silently substitute.
|
||||
- The subagent must not delegate further.
|
||||
|
||||
| Complexity | Model | Effort |
|
||||
|---|---|---|
|
||||
| Single screenshot, one command, bounded lookup | `gpt-5.6-terra` | medium |
|
||||
| Same scope, long logs or fiddly state | `gpt-5.6-terra` | high |
|
||||
| Multi-step GUI workflow, ordinary debugging | `gpt-5.6-sol` | medium |
|
||||
| Risky, ambiguous, or touching credentials/money/user data | `gpt-5.6-sol` | high |
|
||||
|
||||
Default to `sol` when a mistake could change user data, spend money, publish, delete, or
|
||||
overwrite. Default to `terra` when the action is reversible and easy to verify.
|
||||
|
||||
## Sandbox: the part that used to silently fail
|
||||
|
||||
GUI access requires `--sandbox danger-full-access`. This is not optional and there is no
|
||||
narrower mode that works.
|
||||
|
||||
Measured on this box (Wayland, Hyprland 0.56.2):
|
||||
|
||||
| Sandbox | `grim` screenshot | `hyprctl` |
|
||||
|---|---|---|
|
||||
| `read-only` | fails, `failed to create display` | fails, `Couldn't set socket timeout` |
|
||||
| `workspace-write` | fails, `failed to create display` | fails |
|
||||
| `workspace-write --add-dir /run/user/1000` | still fails | still fails |
|
||||
| `danger-full-access` | works | works |
|
||||
|
||||
The sandbox passes `WAYLAND_DISPLAY` and `XDG_RUNTIME_DIR` through as environment
|
||||
variables but blocks the compositor sockets themselves, so the failure looks like a
|
||||
missing display rather than a permission error. `--add-dir` does not fix it.
|
||||
|
||||
Because `danger-full-access` removes the sandbox entirely, keep the blast radius in the
|
||||
brief instead: name the exact commands allowed, and forbid everything else.
|
||||
|
||||
## Run it
|
||||
|
||||
```bash
|
||||
cd "$PWD" && timeout 900 codex exec \
|
||||
--ignore-user-config \
|
||||
--model gpt-5.6-terra \
|
||||
--config model_reasoning_effort="medium" \
|
||||
--config approval_policy="never" \
|
||||
--sandbox danger-full-access \
|
||||
--ephemeral \
|
||||
--skip-git-repo-check \
|
||||
--output-last-message /tmp/codex-gui-1.md \
|
||||
--cd "$PWD" - <<'TASK'
|
||||
<brief from the template below>
|
||||
TASK
|
||||
cat /tmp/codex-gui-1.md
|
||||
```
|
||||
|
||||
Notes that matter:
|
||||
|
||||
- Always feed the brief on stdin via a **quoted** heredoc (`<<'TASK'`) so the shell does
|
||||
not expand anything in it. The trailing `-` is what tells Codex to read stdin.
|
||||
- `--output-last-message` gives you the clean report; stdout also carries the reasoning
|
||||
stream, which is what you want when a run fails.
|
||||
- Give screenshots a path you can reach afterward. Prefer your scratchpad directory.
|
||||
- A nonzero exit or empty report file is a failure even if stdout printed something.
|
||||
Check both.
|
||||
|
||||
## Brief template
|
||||
|
||||
Codex starts with zero context.
|
||||
|
||||
```
|
||||
You are a subagent with direct access to the live graphical session.
|
||||
|
||||
Environment: Wayland + Hyprland. Available: grim (screenshot), slurp (region),
|
||||
wtype (typing), hyprctl (window control and JSON introspection), xdotool
|
||||
(XWayland windows only), playwright, google-chrome-stable, firefox.
|
||||
|
||||
You CANNOT view images. Never describe the contents of a screenshot. Capture it,
|
||||
report the absolute path, and let the caller look at it.
|
||||
|
||||
Hard constraints:
|
||||
- Run only these commands: <explicit list>
|
||||
- Do not close, move, or resize the user's existing windows unless told to.
|
||||
- Do not type into or click on windows the task does not name.
|
||||
- Do not delegate further or invoke Codex/Claude recursively.
|
||||
|
||||
Report, in these sections:
|
||||
- Summary: what you did.
|
||||
- Screenshots: absolute path of each, and what each was meant to capture.
|
||||
- Structural state: relevant `hyprctl -j clients` output or command stdout, verbatim.
|
||||
- Commands run: each with its exit code.
|
||||
- Open questions: anything you could not determine without vision.
|
||||
|
||||
Task:
|
||||
<self-contained task>
|
||||
```
|
||||
|
||||
Pass raw evidence. Do not tell Codex the answer you expect it to find.
|
||||
|
||||
## Desktop cookbook (verified available here)
|
||||
|
||||
Prefer structured text over pixels wherever possible, since that is the part Codex can
|
||||
reason about.
|
||||
|
||||
```bash
|
||||
grim /path/shot.png # whole screen
|
||||
grim -g "$(slurp)" /path/region.png # region (interactive, needs a human)
|
||||
hyprctl -j clients # every window: class, title, at[x,y], size[w,h], workspace
|
||||
hyprctl -j activewindow # focused window
|
||||
hyprctl -j monitors # geometry and scale
|
||||
hyprctl notify -1 3000 "rgb(44ccff)" "message"
|
||||
wtype 'text to type' # types into the focused window
|
||||
```
|
||||
|
||||
`hyprctl -j clients` is the highest-value call: it returns exact window rectangles, so
|
||||
Codex can position and identify windows without seeing anything.
|
||||
|
||||
## Known limits, state honestly
|
||||
|
||||
- **No synthetic mouse clicks.** `ydotool` is not installed and the user is not in the
|
||||
`input` group, so `/dev/uinput` is not writable. There is no working click injection.
|
||||
If a task needs a click, say so and ask the user, rather than having Codex flail.
|
||||
- **Hyprland 0.56 changed the dispatch API** to a Lua form (`hl.dsp.window.close()`).
|
||||
Old `hyprctl dispatch <name>` strings error out. Verify a dispatcher before relying on
|
||||
it.
|
||||
- `xdotool` only reaches XWayland clients, not native Wayland ones.
|
||||
- **Screenshots are downscaled when you Read them.** A 3440x1440 capture is shown to you
|
||||
at 2000x837. If you derive coordinates from the image, multiply by the stated factor
|
||||
before handing them to anything.
|
||||
|
||||
## After the run
|
||||
|
||||
- Read the screenshot yourself before believing any claim about UI state.
|
||||
- Treat the report as a claim. Spot-check load-bearing parts against the raw output.
|
||||
- On failure, report the model, the exact command, and the error. Retry once only for
|
||||
transient faults, on the same model family. If the error is `failed to create display`,
|
||||
the sandbox flag was wrong, not the task.
