# LibreOffice Draw: a computer-use environment built from a one-line request
**The real LibreOffice Draw 24.2 drawing app running on an Ubuntu 24.04 desktop, as an [agentenv](https://pypi.org/project/agentenv-framework/) computer environment. An agent completes the task only through screenshots, mouse and keyboard, and a verifier grades the saved files with no model.**
Claude Code built this environment from a one-line request in about 26 minutes, with only REA's build skill and MCP tools; [How it was made](#how-it-was-made) has the request and the steps. LibreOffice Draw opens a small order fulfillment diagram, `Documents/order-flow.odg`, at launch: four boxes, Order Received, Pick Items, Pack Items and Ship Order, joined by connectors. The agent has to relabel the Pick Items box to Pick and Scan and save. It sees only the screen and acts only with the mouse and keyboard.
## Watch
- Agent runs (Claude Code with Claude Sonnet 5.5): [run 1](media/solve-1.mp4), [run 2](media/solve-2.mp4), [run 3](media/solve-3.mp4)
- Witness, which proves the task can be done through the computer: [witness.mp4](media/witness.mp4)
Each video is the computer's own screen recording at 10 frames per second.
## The task
> In my order fulfillment diagram, Documents/order-flow.odg, relabel the "Pick Items" box to "Pick and Scan" and save it.
`bundle/artifacts/relabel-pick-box-check/verify.py` reads the app's files through the computer's `data/get` view and passes only if every check holds:
| Check | Kind | File |
| --- | --- | --- |
| `relabeled` | `text_equals` | `Documents/order-flow.odg` |
| `box-above-kept` | `text_equals` | `Documents/order-flow.odg` |
| `box-below-kept` | `text_equals` | `Documents/order-flow.odg` |
| `four-boxes` | `member_count` | `Documents/order-flow.odg` |
An `.odg` file is a zip, and REA reads `content.xml` inside it. The checks find each box by the name it was given in the drawing (`draw:name`, Step 1 to Step 4), never by position or by the ids LibreOffice generates when it saves: Step 2 must read "Pick and Scan" exactly, Step 1 and Step 3 must keep "Order Received" and "Pack Items", and the page must still hold four boxes (`member_count`). Every check came from REA's draft: Claude Code switched the boxes' selectors from LibreOffice's generated `xml:id`s to their names and kept the count as REA wrote it.
## Results
3 of 3 runs passed, about $0.74 per run.
| Run | Outcome | Turns | Cost | Video |
| --- | --- | --- | --- | --- |
| 1 | passed | 11 | $0.99 | [video](media/solve-1.mp4) |
| 2 | passed | 12 | $0.49 | [video](media/solve-2.mp4) |
| 3 | passed | 12 | $0.75 | [video](media/solve-3.mp4) |
## Run it
You need Docker. `agentenv-framework` builds the computer: Ubuntu 24.04 with the app installed from Ubuntu's archive (`libreoffice-draw` 24.2.7, with `fonts-liberation`).
```bash
pip install agentenv-framework==0.9.1431
hf download earakely-scale/LibreOfficeDrawFromRequestComputerEnv-REA --repo-type dataset --local-dir draw-request
agent-env run draw-request/bundle --task relabel-pick-box --agent claude-code --model <model>
```
The agent needs a model provider configured for agentenv. `--task smoke` only boots the computer, with no agent. `bundle/README.md` describes the bundle in detail.
## How it was made
Claude Code built this environment from a one-line request, given only [REA](https://github.com/morluto/rea)'s build skill and REA's MCP tools:
> Build me a LibreOffice Draw environment where the agent relabels a box in a small diagram and saves it.
It asked only the skill's upfront questions, wrote no app-specific scripts, and finished in about 26 minutes. The steps were REA's usual ones:
1. **Capture.** REA launched LibreOffice Draw on a Linux desktop and recorded its package, windows and opened files while the edit was made. It also recorded the app's state folders before and after.
2. **Export.** REA turned the capture into an agentenv `computer_app`. It installs the app, seeds the starting files, starts the app, and waits for its main window. It also serves typed views of the app's files for verifiers.
3. **Task.** The task's checks were validated against the capture: they fail on the starting state and pass on the captured end state.
4. **Witness.** In a fresh computer, the edit was made through computer actions alone, and the checks were read at four stages. They held on the first try:
| Stage | Checks |
| --- | --- |
| `seed` | fail, as expected: the box reads Pick Items; the kept checks pass |
| `after_edit` | pass |
| `near_miss` | fail, as expected: the box was retyped as "Pick and Scna" |
| `after_reset` | fail, as expected: `data/reset` restored the seed |
The agent runs came after the build: Claude Code with Claude Sonnet 5.5 (`--model anthropic/claude-sonnet-5-5 --no-emulate`, on an amd64 host) solved the task 3 times, each run recorded.
## What's inside
```
bundle/ the agentenv bundle: envs/ (app module, seed files), tasks/, artifacts/ (verifier), evals/
media/ witness and agent-run recordings (MP4) with short GIF previews
results.json the runs above, with each check's result
```
## Limits
- The boxes are found by the names they were given in the drawing, Step 1 to Step 4. A new box drawn in place of Pick Items has no such name and fails, even when the drawing reads right. Ship Order and the connectors are not checked.
- The seed holds LibreOffice's user profile as the capture left it, including its icon cache (`~/.config/libreoffice/4/cache`, 599 files); the export left LibreOffice's document-recovery list out of it. LibreOffice started cleanly in the witness and in every run.
- The bundle installs `fonts-liberation` beside the app as an extra package; the build asked for it.
- The computer installs whatever `libreoffice-draw` Ubuntu 24.04's archive holds at build time (24.2.7 for these runs); it is not pinned.
- Three runs is a small sample: the solve rate shows the task is solvable, not how hard it is.
## Licences
The bundle code, the task and the synthetic seed files are Apache-2.0. LibreOffice Draw itself is not included: the computer installs it from Ubuntu's archive (`libreoffice-draw` 24.2.7, with `fonts-liberation`) at build time, under its own licence (MPL-2.0).
