| # LibreOffice Writer: a computer-use environment |
|
|
|  |
|
|
| **The real LibreOffice Writer 24.2 word processor 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.** |
|
|
| Writer opens a delivery notice from a corner shop. The agent has to move the delivery to a new date by editing the line under the title, keep the time, and save the document. 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) |
| - Scripted 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 the delivery notice open in LibreOffice Writer, move the delivery to Monday 24 November (same time, 8am to 10am) by changing the date under the title, then save the notice. |
|
|
| `bundle/artifacts/move-delivery-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 | |
| | --- | --- | --- | |
| | `new-date` | `value_equals` | `Documents/notice.odt` | |
| | `title-kept` | `value_equals` | `Documents/notice.odt` | |
| | `signature-kept` | `value_equals` | `Documents/notice.odt` | |
|
|
| The `.odt` is a zip. The checks read `content.xml` inside it and find paragraphs by their paragraph style, never by position. The subtitle must read the new date exactly, and the title and signature must be unchanged. |
|
|
| ## Results |
|
|
| 3 of 3 runs passed, about $0.58 per run. |
|
|
| | Run | Outcome | Turns | Cost | Video | |
| | --- | --- | --- | --- | --- | |
| | 1 | passed | 11 | $0.72 | [video](media/solve-1.mp4) | |
| | 2 | passed | 14 | $0.57 | [video](media/solve-2.mp4) | |
| | 3 | passed | 10 | $0.44 | [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-writer` 24.2.7). |
|
|
| ```bash |
| pip install agentenv-framework==0.9.1431 |
| hf download earakely-scale/LibreOfficeWriterComputerEnv-REA --repo-type dataset --local-dir writer |
| agent-env run writer/bundle --task move-delivery --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 |
|
|
| [REA](https://github.com/morluto/rea) built this environment from a real session with the app: |
|
|
| 1. **Capture.** REA launched LibreOffice Writer on a Linux desktop and recorded its package, windows and opened files while a scripted user made the edit. 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 and runs.** Scripted computer actions solved the task in a fresh computer, and the verifier failed before, passed after and failed again after `data/reset`. Then an agent solved it 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 seeded Writer profile turns off Writer's revision IDs (Tools > Options > Writer > Comparison, `StoreRSID`). With them on, which is Writer's default, retyping text splits the paragraph into styled runs, and the checks, which read the paragraph's first run, would fail a correct edit. A check on a paragraph's whole text would remove this need. |
| - The subtitle paragraph is found by its `Subtitle` style. An edit that changes the paragraph's style fails even if the text is right. |
| - The computer uses the `libreoffice-writer` version in Ubuntu 24.04's archive at build time; 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 Writer itself is not included: the computer installs it from Ubuntu's archive (`libreoffice-writer` 24.2.7) at build time, under its own licence (MPL-2.0). |
