Ready-to-use prompt

I work as a water / wastewater treatment plant / system operator. Part of my job is to record operational data, personnel attendance, or meter and gauge readings on specified forms.

Context: We use Records management software and Microsoft Word.
Operation: [kitchen, production line, security desk]
Data to record: [quantities, times, readings, items issued]

Design a log format and draft today's entries from my notes. Mark gaps with [CHECK]. Use plain language and headings where they help, and mark anything you had to guess with [CHECK].

10-minute exercise: Production log entry

Step 1Pick a real example: the next time you record operational data, personnel attendance and meter and gauge (today). Leave out names and identifying details.
Step 2Fill in [Operation] and [Data to record] with the real details, then run the prompt.
Step 3Check entries against counts or readings before signing.

AI will happily make up numbers, names and dates. Every fact in the draft needs checking against your source.
