I used to walk into meetings with a plan that only I had poked at. It sounded fine in my head. Ten minutes in, someone asked a question I had not thought about, and the whole thing wobbled. The fix was not more slides. It was five quiet minutes with AI before I opened the calendar invite.
The idea is simple. You already have a plan, a proposal, or a half-written update. Before you present it, ask a model to attack it like a sharp colleague would. Not to rewrite it. To find the soft spots.
What to paste in
Keep the prompt short and specific. Something like:
Here is the plan I am about to take into a meeting:
[paste your outline, email draft, or bullet list]
Act like a sharp colleague who wants this to succeed. List:
1. The three weakest assumptions
2. Two questions someone will almost certainly ask
3. One thing I should cut or simplify before I go in
Do not rewrite my plan. Just stress-test it.That is enough. You do not need a persona, a role play, or a long system prompt.
What you get back
Usually three useful things.
First, the assumptions you forgot you were making. Things like “finance will be fine with this” or “the timeline is obvious.” Seeing them written down is half the win.
Second, the questions you would rather rehearse once than invent under pressure. I keep those in a note and answer them in one sentence each before I join.
Third, the cut. Almost every plan has one paragraph, slide, or side quest that does not earn its place. Cutting it early is kinder than watching the room glaze over.
A Thursday morning version
If you only have five minutes before the call, paste the chat thread or the email chain instead of a polished brief. Ask for the weakest assumption and the one question to prepare for. That alone beats walking in cold.
It does not replace thinking. It just catches the holes while there is still time to fill them.
When to skip it
Skip the stress-test when the meeting is a listening session, a personal catch-up, or something you are still exploring out loud. Stress-testing half-formed thoughts can make you sound more certain than you are. Save it for the moments when you are about to recommend a path.
Try it once
Pick the next meeting where you are bringing a plan. Paste the outline, run the prompt above, and fix one thing before you join. That is the whole habit.
If it saved you an awkward question, keep the prompt. If it did not, tweak the ask. The goal is a sharper five minutes, not another process to maintain.
