“But it worked last time”
Suppose a few rounds of editing produced a useful meeting summary. You save the last prompt. A week later, you paste it into a new conversation and the result omits deadlines again. What happened? The table format, example and way of marking gaps may have stayed in the old chat. The last instruction did not necessarily contain everything.
Different material or a different model can also change the result, but first let’s check we moved the entire instruction. We suggest storing a complete task card in your library. Start with three jobs you really return to: editing an email, extracting agreements and preparing interview questions. That is easier to maintain than a folder of prompts saved “for later.”
What do you need to know to use this card?
Write down what the instruction is for, what to paste and what must not change. Add a short fictional input without customer data and the expected kind of answer. The next person will know how to begin and whether they received what was intended.
A shared document or folder of text files is enough. “Meeting summary — decisions and deadlines” makes a card findable by task. “Superprompt v7 final” requires remembering what its author had in mind. Below is a template for a card.
Added a condition? Leave the reason too
Suppose the instructions gain a ban on filling in dates. Explain why: “The model gave a specific day when the note said only ‘next week.’” Someone shortening the prompt will understand why the sentence exists. Without context, they might consider it unnecessary.
Run the new version on the old example and one fresh input. Two trials do not establish reliability, but they may reveal that fixing dates broke something else. Add further troublesome cases to a shared set. Record the model and trial date too; a prompt version number alone does not tell the whole story.
A library should be handy, not impressive in size
Name someone familiar with each card’s use. It will be easier to decide whether a new condition helps or clashes with a previous one. Occasionally merge duplicates, remove unused instructions and update limitations.
Replace access keys, private addresses and confidential passages with visible placeholders. They should not travel with a template. Finally, open a new conversation and perform the task using only the card. If you still have to explain something aloud, you have found the missing part of the instruction.
