LibreOffice Writer: a computer-use environment

The real LibreOffice Writer 24.2 word processor running on an Ubuntu 24.04 desktop, as an agentenv 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, run 2, run 3
• Scripted witness, which proves the task can be done through the computer: 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

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).

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 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).
