+
+![An agent solving the task in Zim](media/hero.gif)
+
+**The real Zim 0.75 desktop wiki 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 27 minutes, with only REA's build skill and MCP tools; [How it was made](#how-it-was-made) has the request and the steps. Zim opens a notebook, Notes, at launch, on its empty Home page. The notebook's Meeting Notes page holds a weekly sync's attendees, decisions and two action items written as unchecked checkboxes. The agent has to open Meeting Notes, add a third action item, "Dana to update the release checklist", as an unchecked checkbox, and save the page. 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 Zim notebook, add a new action item to the Meeting Notes page: "Dana to update the release checklist". Add it as an unchecked checkbox in the Action items list, like the others there, and save the page.
+
+`bundle/artifacts/add-action-item-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 |
+| --- | --- | --- |
+| `dana-item` | `lines_present` | `Notebooks/Notes/Meeting_Notes.txt` |
+| `dana-once` | `line_count` | `Notebooks/Notes/Meeting_Notes.txt` |
+| `other-items-kept` | `lines_present` | `Notebooks/Notes/Meeting_Notes.txt` |
+
+A Zim page is a text file in Zim's wiki markup, here `Notebooks/Notes/Meeting_Notes.txt`, where an unchecked checkbox is written `[ ]` at the start of its line. The checks read the page line by line: it must have the line "[ ] Dana to update the release checklist", only one line may mention Dana's item, and the two existing action items must still be there. REA's draft suggested the first check as written; Claude Code added the other two.
+
+## Results
+
+3 of 3 runs passed, about $0.57 per run.
+
+| Run | Outcome | Turns | Cost | Video |
+| --- | --- | --- | --- | --- |
+| 1 | passed | 11 | $0.71 | [video](media/solve-1.mp4) |
+| 2 | passed | 12 | $0.25 | [video](media/solve-2.mp4) |
+| 3 | passed | 11 | $0.74 | [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 (`zim` 0.75.2).
+
+```bash
+pip install agentenv-framework==0.9.1431
+hf download earakely-scale/ZimFromRequestComputerEnv-REA --repo-type dataset --local-dir zim-request
+agent-env run zim-request/bundle --task add-action-item --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 Zim environment where the agent adds an action item to a meeting-notes page.
+
+It asked only the skill's upfront questions, wrote no app-specific scripts, and finished in about 27 minutes. The steps were REA's usual ones:
+
+1. **Capture.** REA launched Zim 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 item was added 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 page has no line for Dana's item; the kept-items check passes |
+| `after_edit` | pass |
+| `near_miss` | fail, as expected: the new item's checkbox was ticked |
+| `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
+
+- Zim starts on the notebook's Home page, which is empty, so the agent must open Meeting Notes from the index on the left. After `data/reset`, Zim reopens on the last page it showed instead: its `~/.cache/zim` is not part of the seed.
+- The new item's place on the page is not checked: the line passes anywhere, not only in the Action items list. A ticked checkbox (`[*]`), a bullet or different wording fails.
+- The verifier reads the page as soon as the agent stops. Zim also saves an edited page by itself on a timer (`autosave_timeout=15` in its preferences), so a run that leaves the saving to Zim can be graded on the unsaved page. The prompt asks for a save, and all three runs passed.
+- The computer installs whatever `zim` Ubuntu 24.04's archive holds at build time (0.75.2 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. Zim itself is not included: the computer installs it from Ubuntu's archive (`zim` 0.75.2) at build time, under its own licence (GPL-2.0-or-later).

+0.9.1431.
+
+- `envs/zim/` is a computer app on the `ubuntu-24.04` base with the `reference` driver, for
+  `amd64` and `arm64`. It installs `zim` from the distribution archive, launches `sh -c cd "$HOME" 2>/dev/null; exec 'zim'` at boot and is ready
+  when a window of class `Zim` appears.
+- The app opens no document at launch, since the seed holds 2 documents (~/Notebooks/Notes/Meeting_Notes.txt, ~/Notebooks/Notes/notebook.zim) and the app opens one only when it holds exactly one.
+- Owned paths: `~/.config/zim`, `~/Notebooks/Notes`.
+  `data/get` returns their files and a typed JSON view of each; `data/reset` restores the seed.
+- Seed: 4 file(s) made for the task, as saved at checkpoint `seed`.
+  Text files and dconf keys spell the capture host's name as `localhost`, `user@host` as `user@localhost`
+  and the home as `/home/user`, which the computer respells to its own at boot.
+- `tasks/smoke.json` deploys the app.
+
+Run the task with `agent-env run <this folder>`, or only the deploy with `--task smoke`.
+
+The seed was made for this task, not taken from a user's own data; read `envs/zim/seed/` before publishing the bundle.
+
+## Task `add-action-item`
+
+`tasks/add-action-item.json` deploys the app, has the agent work through the computer from the prompt below, and grades
+the outcome with `artifacts/add-action-item-check/verify.py`, which reads the app's `data/get` views and needs
+no model. `evals/zim.toml` names it, so a run of the bundle runs it.
+
+> In my Zim notebook, add a new action item to the Meeting Notes page: "Dana to update the release checklist". Add it as an unchecked checkbox in the Action items list, like the others there, and save the page.
+
+Checks, each of which must pass:
+
+- `dana-item`: `{"kind":"lines_present","file":"Notebooks/Notes/Meeting_Notes.txt","lines":["[ ] Dana to update the release checklist"]}`
+- `dana-once`: `{"kind":"line_count","file":"Notebooks/Notes/Meeting_Notes.txt","contains":"Dana to update the release checklist","equals":1}`
+- `other-items-kept`: `{"kind":"lines_present","file":"Notebooks/Notes/Meeting_Notes.txt","lines":["[ ] Priya to send the revised budget","[ ] Marco to book a room for the offsite"]}`
+
+REA kept the task because its checks fail on the seed (`dana-item`, `dana-once`) and all
+pass on the captured end state.
+
+To measure a solve rate, run the task k times (3 by default) with the agent and model to measure, and count the runs
+whose summary line says `passed`; a run that says `failed` did not finish and is run again rather than counted:
+
+    agent-env run <this folder> --task add-action-item --agent claude-code --model MODEL
