Zim Desktop Wiki computer app

Exported by REA's export-desktop-application from a capture of the zim package (capture Evidence ev_d45c7017d2d25004cdb8f6d7204b4581a11cc51e2b2146b77fab7d34a724532e). It was checked against agentenv-framework 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
