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."
description: Compatibility guidance for requests that explicitly invoke the old Claude Code computer-delegate workflow on this Hyprland desktop. For ordinary desktop work, use hyprland-computer-use and the local desktop MCP tools.

# Claude Code Computer Delegate
# Computer delegate compatibility
## The one thing to understand first
The current desktop workflow is documented in
[hyprland-computer-use](../hyprland-computer-use/SKILL.md).
Use its `hyprland_desktop` MCP tools directly when available.
**Codex is the hands. Claude Code is the eyes.**
The previous machine-specific assumptions are obsolete: `ydotool` is installed,
the host has a user-owned input socket, and image viewing depends on the caller's
actual tools. Do not assume Codex cannot view screenshots or require an unrestricted
agent sandbox for ordinary desktop work.
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.
If the user explicitly requests delegation, use the available delegation workflow
and give the delegate a bounded app/task. Check that it actually has the desktop MCP
tools and image-viewing capability. If it cannot inspect images, have it return the
screenshot to the caller for interpretation. Never claim visual verification from a
command's exit status alone.
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.
This bridge's Codex MCP registration does not automatically configure Claude Code.
Configure the same stdio server separately in any other client that needs it.

# 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.
