The five lines
Paste them into Claude one at a time when the answer feels too confident, too agreeable or too vague. Not all five at once — stacked into one message they cancel each other out and you get a wall of hedging instead of an answer.
Same chat as the answer you are questioning. These only work because the model can still see what it just said. Open a fresh window and line 4 has nothing to argue against, so it invents a decision and then disagrees with that instead.
“Ask me up to three questions before you start.”
Before it answersAsk me up to three questions before you start.
What it does. Stops it guessing. Instead of filling your gaps silently and answering anyway, it has to say out loud what it does not know. Half the time the questions it asks are the ones you had not thought to answer, which tells you more about your own brief than the answer would have.
What it does not do. It will not ask good questions off a thin request. If all you gave it was one line, expect one lazy question back. And "up to three" is a ceiling, not a quota — some jobs get one. It also does not stop it answering; it just makes it earn the answer first.
“List the assumptions you’re making.”
The quiet oneList the assumptions you’re making.
What it does. Pulls the invisible bits into the open — the budget it assumed, the audience it assumed, the fact it decided you were solo when you have two contractors. Usually one item on that list is wrong, and that one item is the whole reason the answer felt off.
What it does not do. It is listing the assumptions it can see, which is not the same as all of them. It cannot list the assumption it does not know it made. Treat the list as a starting point you argue with, not a completed audit.
“Give me three options and recommend one.”
For decisionsGive me three options and recommend one.
What it does. Breaks the single-answer trap. The moment it has to produce three and rank them, it has to hold a reason for the ranking — and the reason is the useful part, more than the pick.
What it does not do. The three will not always be genuinely different. You will sometimes get one real option and two obviously worse ones dressed up to make the first look considered. If two and three are straw men, ask for three it would actually defend.
“Argue against your own decision.”
The best oneArgue against your own decision.
What it does. The strongest of the five. It turns the model off your side for one message, and the objections that come back are usually the ones you have been walking past for a fortnight. Run this before you spend money, not after.
What it does not do. It is arguing on command, not because it believes any of it — and it will fold the second you push back. That is not a second opinion from someone with skin in the game. It is a list of the objections a reasonable person might raise, which is worth having, and is not the same thing.
“Turn the final answer into a checklist and start with step one.”
Run it lastTurn the final answer into a checklist and start with step one.
What it does. Converts advice into something you can start in the next ten minutes. The second half is the half that matters — without "start with step one" you get a tidy fourteen-item list and the exact same paralysis you had before, just better formatted.
What it does not do. A checklist is not a plan. There are no dependencies in it, no dates, and no sense of which step is the hard one. It also will not catch bad advice — it is reformatting what is already above it, so mushy reasoning becomes a very neat list of mush.
Yes, they really are one line each
There is a whole cottage industry in four-hundred-word prompts full of role-play and formatting rules. These are five short instructions because you are not configuring anything — you are asking for one specific behaviour in a conversation the model can already see. The context is doing the work. The line is just pointing at it.
How to actually fire them
Line 1 goes in before it starts. Lines 2 to 5 go in after you have an answer you are not sure about. That is the whole system.
Ask for the thing, then send line 1 before it answers
Describe what you want, then paste "Ask me up to three questions before you start." on its own. Answer whatever it asks. Everything downstream is built on those answers, so this thirty seconds is the highest-value part of the whole exchange.
Read the answer and decide if it needs pressure
Most answers do not. If it is a low-stakes bit of copy, take it and move on. Reach for lines 2 to 5 when there is money, time or a client on the other side of the decision.
Send line 2, then argue with exactly one item
Ask for the assumptions, read the list, and pick the one that is wrong. Correct just that one and let it redo the answer. Correcting five at once gets you a rewrite that ignores three of them without mentioning it.
Line 3 if you are choosing, line 4 if you have already chosen
Three options when you are still deciding. The argument against when you have made up your mind and want to know what you are walking into. Line 4 is the uncomfortable one and it is the one worth running.
Finish with line 5 and do step one now
Not later, now, while the chat is still open. The gap between "I have a good plan" and "I have started" is where this whole exercise usually goes to die.
The mistake almost everyone makes
Pasting all five at the top of a fresh chat as some kind of system prompt. They are not settings — they are five separate interruptions, and each one only works because there is something specific in front of it to interrupt. Fired as a block, you get a very cautious model that asks three questions about a decision it has not been told about yet.
How to spot a yes-man answer
You do not need these lines on every reply. You need them the moment you notice one of these four. Each one has a line that fixes it.
It restated your idea in better words and called that analysis
Use line 4You described a plan, it handed the plan back polished, and somewhere in there was the word "solid". Nothing was tested. It has agreed with the framing so completely that it never considered a different one. Ask it to argue against the decision and watch what surfaces.
There are no numbers and no tradeoffs
Use line 2Real advice has a cost attached — this takes longer, that one is cheaper but worse, this only works if you already have a list. An answer with no downside anywhere in it has usually assumed away the hard parts. Get the assumptions out and you will find them.
It changed its answer the second you pushed back
The big oneYou said "hmm, are you sure?" and gave it no new information, and it reversed. That is not learning, that is agreeableness — and it means the original answer was never held with any confidence either. Try it deliberately once. It is genuinely clarifying, and slightly depressing.
It answered instantly on almost no information
Use line 1You gave it four sentences about your business and got a confident twelve-month strategy. It did not stop to ask what you sell or who to. It filled every gap with the most average version of that gap, so what you are reading is the industry median wearing your name.
What this will not fix
Being straight with you, because a prompt pack that claims to make AI reliable is a prompt pack you use once and then stop trusting.
These do not make it correct. They make it legible.
Every one of these five gets you more of the model's working: the questions, the assumptions, the alternatives, the counter-case, the steps. That is a much better thing to check than a paragraph of confident prose. But you are still the one checking. A well-reasoned wrong answer is still wrong — it is just easier to catch, which is the entire point.
A few other honest limits:
- It cannot know what you did not tell it. No line conjures your actual margins, your client's temperament or the thing you already tried in March. If the information is not in the chat, the assumptions list will be full of plausible guesses.
- Line 4 is a performance. A good and useful one, but it is arguing because you asked, not because it disagrees. Do not read a strong counter-argument as evidence you are wrong, and do not read a weak one as evidence you are right.
- Used on everything, they cost you more than they save. Five rounds of interrogation on a caption is a waste of an afternoon. Save them for decisions with money or a client attached.
- They will not stop it being wrong confidently. Nothing does. The fix is that you now have four other angles on the same answer, and confident wrongness is much harder to sustain across all of them at once.
Where these came from
These are five I actually use, not five I made up for a video. Line 4 is the one I resisted longest, because it is genuinely annoying to be told the case against something you have already decided to do — which turned out to be exactly why it earns its place.
