At a 30-person distributor in Greeley, one salesperson got quote follow-ups down from 12 minutes to 3. She had spent two weeks refining how she asked, and it worked. Everyone else was still at 12 minutes, or had tried once, gotten something generic, and gone back to typing.
Then she took 3 weeks of leave. The prompt was in her personal notes app. For 3 weeks, follow-ups took 12 minutes again.
The company had bought a tool. It had not kept anything. That’s the difference a prompt library makes, and it is a shared document, not a piece of software.
What a library entry actually contains
The prompt itself is the smallest part. An entry that survives being handed to a coworker has 6 things in it.
A name and a trigger. “Quote follow-up, no response after 5 days.” Somebody scanning the list should know in 2 seconds whether this is the one.
The prompt text, ready to copy. Written out in full. Not a description of the prompt, not “ask it to summarize nicely.” The words.
What you paste in with it. The original quote, the customer’s last email, your price list. Half of what makes a good prompt good is the material handed to it, and that part gets left out of every screenshot on the internet.
One example of good output. This is the most valuable line in the entry and the one people skip. It tells the next person what “working” looks like, so they know whether to keep editing or stop.
What to check before it goes out. Two or three specific items. Prices match the quote. No commitment to a date we haven’t confirmed. Customer’s name spelled the way they spell it.
Who owns it and when it was last touched. A prompt that nobody has looked at in 8 months is a liability, because the model behind it changed and nobody re-tested.
Where it lives
Wherever your team already looks things up. A shared doc, a wiki page, a folder in the drive. It must not be a personal notes app, a pinned message, or somebody’s memory.
Eight to twelve entries is a real library for a business under 100 people. Beyond that, people stop reading it and start guessing again. When a new one goes in, ask which one comes out.
Keep the writing plain enough that a new hire could use an entry on their second day without asking. If they can’t, the entry isn’t finished.
Start with what you already have
This is the part you can do this week, and it costs nothing.
Find the 2 or 3 people in your company already using these tools regularly. There always are some, and it is usually not who you’d guess. Ask each of them for the single prompt they use most. Not their best idea, the one they actually reach for.
Put those in one document. Add the paste-in list, one good example, and the review step for each. That is 3 entries, and it took an hour.
Then leave it alone for a month and watch which ones get used. The ones nobody touches were somebody’s theory. The ones that get used are your library, and now they belong to the business rather than to whoever happens to be in the office.
