# CherryTree computer app

Exported by REA's `export-desktop-application` from a capture of the `cherrytree` package
(capture Evidence `ev_6d194ec1e9120b0e3eea507aaf60cf6fea6b34ead242762bca5b9676f145e254`). It was checked against agentenv-framework
0.9.1431.

- `envs/cherrytree/` is a computer app on the `ubuntu-24.04` base with the `reference` driver, for
  `amd64` and `arm64`. It installs `cherrytree` from the distribution archive, launches `sh -c cd "$HOME" 2>/dev/null; exec 'cherrytree' '--new_window'` at boot and is ready
  when a window of class `Cherrytree` appears.
- Installed beside the app because the export was asked for them with `--extra-package`, as a build computer asks
  for the packages its request named: `librsvg2-common`.
- The app opens no document at launch, since the seed holds 2 documents (~/.cache/dconf/user, ~/Documents/home-notebook.ctd) and the app opens one only when it holds exactly one.
- Owned paths: `~/.cache/dconf`, `~/.config/cherrytree`, `~/Documents`.
  `data/get` returns their files and a typed JSON view of each; `data/reset` restores the seed.
- Seed: 5 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.
- Neither owned nor seeded, so the app starts without what it saved there: these files or folders, which changed
  during the capture, `~/.config/enchant`.
  To own them, capture again naming them with `state_paths` on `start_build_capture`, or `--state-path` on `capture-desktop-application`.
- Seeded as captured, though the app keeps them for its own running, so a stale one can change how it starts:
  caches `~/.cache`.
- `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/cherrytree/seed/` before publishing the bundle.

## Task `add-chore-line`

`tasks/add-chore-line.json` deploys the app, has the agent work through the computer from the prompt below, and grades
the outcome with `artifacts/add-chore-line-check/verify.py`, which reads the app's `data/get` views and needs
no model. It grades once the app's files have held for 3 s, so a save the app makes on its own within that
time of the agent stopping counts; each result's `settled` is false when they were still changing 15 s after the
first read. `evals/cherrytree.toml` names it, so a run of the bundle runs it.

> In CherryTree, add a line saying Clean the gutters to the Weekend chores note in my notebook Documents/home-notebook.ctd and save it.

Checks, each of which must pass:

- `new-line`: `{"kind":"text_contains","file":"Documents/home-notebook.ctd","pointer":"/root/children/[name=node][@name=Weekend chores]","value":"Clean the gutters"}`
- `kept-water`: `{"kind":"text_contains","file":"Documents/home-notebook.ctd","pointer":"/root/children/[name=node][@name=Weekend chores]","value":"Water the tomato plants"}`
- `kept-sweep`: `{"kind":"text_contains","file":"Documents/home-notebook.ctd","pointer":"/root/children/[name=node][@name=Weekend chores]","value":"Sweep the back porch"}`
- `kept-bulb`: `{"kind":"text_contains","file":"Documents/home-notebook.ctd","pointer":"/root/children/[name=node][@name=Weekend chores]","value":"Replace the hallway bulb"}`
- `kept-library`: `{"kind":"text_contains","file":"Documents/home-notebook.ctd","pointer":"/root/children/[name=node][@name=Weekend chores]","value":"Return the library books"}`
- `three-notes`: `{"kind":"member_count","file":"Documents/home-notebook.ctd","pointer":"/root/children","matching":"[name=node]","equals":3}`

REA kept the task because its checks fail on the seed (`new-line`) 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-chore-line --agent claude-code --model MODEL
