Umbrello computer app

Exported by REA's export-desktop-application from a capture of the umbrello package (capture Evidence ev_ebffa2819a67223adce3ed669534631601016b20653d02c5dd858ce472a0aaeb). It was checked against agentenv-framework 0.9.1431.

• envs/umbrello/ is a computer app on the ubuntu-24.04 base with the reference driver, for amd64 and arm64. It installs umbrello from the distribution archive, launches sh -c cd "$HOME" 2>/dev/null; exec 'umbrello5' "$HOME"/'Documents/library.xmi' at boot and is ready when a window of class umbrello appears.
• At launch the app opens ~/Documents/library.xmi, the seed's one document.
• Owned paths: ~/.config/umbrellorc, ~/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.
• Neither owned nor seeded, so the app starts without what it saved there: these files or folders, which changed during the capture, ~/.config/QtProject.conf. To own them, capture again naming them with state_paths on start_build_capture, or --state-path on capture-desktop-application.
• 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/umbrello/seed/ before publishing the bundle.

Task add-member-email

tasks/add-member-email.json deploys the app, has the agent work through the computer from the prompt below, and grades the outcome with artifacts/add-member-email-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/umbrello.toml names it, so a run of the bundle runs it.

In Umbrello, add an attribute named email of type string to the Member class in the library model Documents/library.xmi and save it.

Checks, each of which must pass:

• email-string: {"kind":"value_equals","file":"Documents/library.xmi","pointer":"/root/children/[name=uml:Model][@xmi:id=m1]/children/[name=packagedElement][@name=Logical View]/children/[name=packagedElement][@name=Member]/children/[name=ownedAttribute][@name=email]/attributes/type","value":"uMUM2QvoIZjRj"}
• member-three-attributes: {"kind":"member_count","file":"Documents/library.xmi","pointer":"/root/children/[name=uml:Model][@xmi:id=m1]/children/[name=packagedElement][@name=Logical View]/children/[name=packagedElement][@name=Member]/children","matching":"[name=ownedAttribute][@xmi:type=uml:Property]","equals":3}
• name-kept: {"kind":"value_equals","file":"Documents/library.xmi","pointer":"/root/children/[name=uml:Model][@xmi:id=m1]/children/[name=packagedElement][@name=Logical View]/children/[name=packagedElement][@name=Member]/children/[name=ownedAttribute][@name=name]/attributes/type","value":"uMUM2QvoIZjRj"}
• memberid-kept: {"kind":"value_equals","file":"Documents/library.xmi","pointer":"/root/children/[name=uml:Model][@xmi:id=m1]/children/[name=packagedElement][@name=Logical View]/children/[name=packagedElement][@name=Member]/children/[name=ownedAttribute][@name=memberId]/attributes/name","value":"memberId"}

REA kept the task because its checks fail on the seed (email-string, member-three-attributes) 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-member-email --agent claude-code --model MODEL
