A small utility should solve one defined problem and make its assumptions visible.

SOURCE STATENew reference guidance; not a recovered test result
GOALRun the first test described in this guide and record the result for scripts, templates, calculators, and browser utilities.
STEPS
Define required inputs, units, valid ranges and the expected output with one worked example.
Keep calculations deterministic and validate invalid or missing inputs before running them.
For scripts and templates, include supported application versions, setup steps and a reversible sample. For browser utilities, keep secrets out of client code.
Test an ordinary case, a boundary case and an invalid case against an independent calculation or manual workflow.
TROUBLESHOOTING
Do not present an estimate as a certified engineering result. Downloaded scripts need readable source or a clear trust and maintenance story.
THINGS TO WATCH FOR
Do not present an estimate as a certified engineering result. Downloaded scripts need readable source or a clear trust and maintenance story.
RESULTThe user can reproduce the worked example and understand why an invalid input was rejected.
