The um CLI workflow
The `um` CLI is a workflow surface rather than a magic game converter. Its value comes from connecting reconnaissance, reusable knowledge, safe automation, testing, and documentation.
The problem to solve
Running a powerful command before understanding its target game or output directory can create an opaque failure and a difficult restore.
Write the expected behavior before changing a game directory or adding a new dependency. A precise failure statement helps you choose a smaller test and prevents a tool from becoming a collection of unrelated experiments.
A practical method
Scan first, search the relevant field notes, back up saves, run the smallest command, inspect output, and only then add asset generation, automation, recording, or packaging.
Keep the base loop, input contract, and save boundary visible. Use original placeholders and a reversible local test whenever the workflow touches game files or generated assets.
How to verify the result
Keep a command log with inputs, output files, process IDs, game state, and the command used to restore the original setup.
Record the engine or tool version, the exact steps, the observed result, and the recovery path. A problem article is useful when another reader can reproduce the check without guessing what changed.
101 / Quick answers
Common The um CLI workflow questions
001What should the first um command prove?+
It should prove that the tool can identify or inspect the intended game without changing protected files or player data.
002What should the first test include?+
One controlled scenario, one expected result, and one reset or restore path. Expand only after that scenario is repeatable.
003What should I document?+
Document the base game or tool version, required ownership, files changed, expected output, and the safe way to undo the experiment.
004What should I avoid?+
Avoid distributing proprietary files, bypassing ownership or anti-cheat checks, and making irreversible changes before a backup and a small test exist.
FAQ
FAQ
What should the first um command prove?+
It should prove that the tool can identify or inspect the intended game without changing protected files or player data.
Can I solve this with a larger prompt?+
Usually not. A smaller prompt tied to one reproducible failure produces a more useful implementation and a clearer review.
Where can I continue?+
Continue with universal modder github explained or universal modder setup or universal modder verification and compare the linked workflow before expanding scope.
