Scribus computer app

Exported by REA's export-desktop-application from a capture of the scribus package (capture Evidence ev_d819eeeffe6b96576a6e675911321db97fd7c68c3aa2179bda8e17c4cc347ecb). It was checked against agentenv-framework 0.9.1431.

  • envs/scribus/ is a computer app on the ubuntu-24.04 base with the reference driver, for amd64 and arm64. It installs scribus from the distribution archive, launches sh -c cd "$HOME" 2>/dev/null; exec 'scribus' "$HOME"/'Documents/jazz-night-flyer.sla' at boot and is ready when a window of class scribus appears.
  • At launch the app opens ~/Documents/jazz-night-flyer.sla, the seed's one document.
  • Owned paths: ~/.config/scribus, ~/Documents. data/get returns their files and a typed JSON view of each; data/reset restores the seed.
  • Seed: 2 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/scribus/seed/ before publishing the bundle.

Task change-flyer-headline

tasks/change-flyer-headline.json deploys the app, has the agent work through the computer from the prompt below, and grades the outcome with artifacts/change-flyer-headline-check/verify.py, which reads the app's data/get views and needs no model. evals/scribus.toml names it, so a run of the bundle runs it.

Change the headline of the event flyer in Documents/jazz-night-flyer.sla to Harbor Lights Jazz Festival and save it.

Checks, each of which must pass:

  • headline: {"kind":"value_equals","file":"Documents/jazz-night-flyer.sla","pointer":"/root/children/[name=DOCUMENT]/children/[name=PAGEOBJECT][@ANNAME=Headline]/children/[name=StoryText]/children/[name=ITEXT]/attributes/CH","value":"Harbor Lights Jazz Festival"}
  • details-untouched: {"kind":"value_equals","file":"Documents/jazz-night-flyer.sla","pointer":"/root/children/[name=DOCUMENT]/children/[name=PAGEOBJECT][@ANNAME=Details]/children/[name=StoryText]/children/[name=ITEXT]/attributes/CH","value":"Saturday, June 14 at 7:00 PM - Maple Street Community Hall"}

REA kept the task because its checks fail on the seed (headline) 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 change-flyer-headline --agent claude-code --model MODEL
