Small utilities are most useful when they fit into the work engineers already do. A tool should make one task faster, leave behind a clear output, and avoid creating another place to manage work.
Use the same basic structure
Most utility workflows can be organized around inputs, checks, notes, exports, and review. That structure works for naming, calculations, documentation, and repeatable handover tasks.
Make outputs easy to review
The output should be easy for another engineer to inspect. Clear labels, assumptions, version notes, and export-friendly formatting matter more than complicated dashboards.
