The anti-brainrot Claude prompt pack

Hey, it's Cindy ๐ŸŒฑ You commented THINK, so here is the full pack: nine prompts across the three habits from the reel, plus the way to install them as a skill.
btw the waitlist for AI System Club is now open! If you're keen on using AI to automate your content, video editing, job search, business or build AI agents, feel free to sign up (only if you want to hehe). Ps. the waitlist gets first dibs:)
the actual problem

It is the prompt shape, not the tool

"Write my strategy" and "here is my problem, what am I missing" go to the same model and produce completely different effects on you. The first one takes the thinking off your plate. The second one puts it back on, with better inputs. Nothing about the app changes between those two messages. Only the shape of what you asked for.

There is real research behind why that matters, and it is more specific than "AI makes you dumb":

  1. ๐Ÿ’ก Confidence in the tool predicts less thinking, confidence in yourself predicts more. A Microsoft Research and Carnegie Mellon survey of 319 knowledge workers covering 936 real AI use cases found that higher confidence in the AI was linked to less critical thinking, while higher confidence in your own ability on the task was linked to more of it. Source: the full paper (PDF), presented at CHI 2025.
  2. ๐Ÿง  Your brain engages less when the tool writes for you. An MIT Media Lab study put people in EEG caps while they wrote essays. The group that leaned on the AI showed the weakest brain connectivity and remembered noticeably less of what they had supposedly written. Source: brainonllm.com.
๐ŸŒฑ Neither study says stop using AI. Both point at the same thing: the default way most people prompt, which is "hand me the finished answer", is the version that costs you something. Every prompt below is built to be the other version.

habit one

Claude as your sparring partner

Use these instead of asking for a plan. The job is to have your thinking pushed on, not replaced.

๐Ÿง  what angles am I missing
I am working through a problem and I want your angles, not your answer. Here is the situation: [describe it honestly, including the constraints you actually have and the thing you would rather not admit].

Give me the four or five genuinely different ways of framing this problem, not four versions of the same frame. For each one, tell me what it assumes, who would naturally see it that way, and what it would push me to do next. Rank them by which you think is most likely to be the frame I am currently missing.

Do not tell me what to do at the end. Instead, ask me which frame feels most uncomfortable, because that is usually the useful one.
๐Ÿ’ก interview me first
Before you give me any opinion on [the decision or problem], interview me. I want to work this out myself with better inputs, not have you decide for me.

Ask me the five sharpest questions that would actually change the answer here. Ask them one at a time and wait for my reply before moving on, and if an answer I give is vague, push back and ask again rather than politely accepting it. Do not soften questions to be nice.

Only after all five, give me your read, clearly labelled as your opinion so I can argue with it, and tell me which of my answers most influenced it.
๐ŸŒฑ break my plan
Here is my plan: [paste it in full, including the timeline and what you are betting on]. Do not improve it for me and do not compliment it.

Find the weakest assumption in it, the thing I have clearly not thought about, and the specific conditions under which this fails badly rather than just underperforms. Then tell me what would have to be true in the world for this plan to work, and rate how confident you are that each of those things is actually true.

Finish by making me defend it: give me your three strongest objections as questions directed at me, and wait for my answers before saying anything else.

habit two

Claude as your early-stage team

This is the one that changed things for me when I had no manager, no lawyer and no budget. It does not replace the team you will eventually build, it gets you to the point where you can build one. These three cover the situations where being new costs you real money.

๐Ÿ‘ฉโ€๐Ÿ’ป is this offer fair
I have been offered [paste the offer in full, or the email, with names removed]. Here is my context: [your audience size or experience level, what is being asked of you, how much work it actually is, and what you have been paid before if anything].

Break the offer down into what is actually being bought: the deliverables, the usage rights, the exclusivity, the timeline, and anything that quietly extends beyond the obvious work. Tell me which parts are standard for something at my level and which parts are unusual or one-sided, and explain why for each.

Then give me an honest read on the number: whether it is low, fair or good for this scope, what the range typically looks like, and which single term (not necessarily the price) is worth the most to me if I could only change one thing.
๐Ÿง  write my counter
I want to counter this offer without losing it. Here is the offer and my read on it: [paste both]. My relationship with them is [new and cold / warm / they came to me], and my honest walk-away point is [number or condition].

Draft the reply in my voice: warm, direct, no apologising for asking, no long preamble. Anchor on the value I bring rather than on my costs. Ask for the specific change I want, give one short reason for it, and include a fallback I would genuinely accept so the conversation has somewhere to land.

Then, separately from the draft, tell me the two most likely responses they will send back and how I should answer each. Flag any sentence in your draft that weakens my position so I can decide whether to keep it.
๐ŸŒฑ read this like a sceptic
Read this document like someone whose job is to protect me, and assume the other side wrote it to favour themselves: [paste the contract, brief or terms].

List every clause that could cost me money, time or ownership later, in plain English, with the exact wording quoted next to each one. Pay particular attention to anything about usage rights, exclusivity, how long it lasts, who owns the work, what happens if either side walks away, and payment timing.

For each item, tell me what a reasonable version of that clause would look like, and rank the whole list by what I should push back on first. Be clear that you are not a lawyer and that anything high-stakes needs a real one, then tell me which specific items on your list you think genuinely warrant that.
๐Ÿ’ก Where the line is. This makes you a much better-informed amateur, which is a real upgrade on being an uninformed one. It is not legal or financial advice. Use it to understand what you are looking at and to write better questions, then pay a professional for anything where being wrong is expensive.

habit three

Learn deeper, not faster

Summaries feel like learning and mostly are not. You get the shape of the thing and none of the structure. These three ask for the parts a summary throws away.

๐Ÿ’ก the intersection
I understand [topic A] reasonably well and [topic B] reasonably well, but not what happens where they meet. Explain the intersection.

Show me where the two genuinely interact rather than sit next to each other, where an idea from one breaks or has to be modified in the other, and what someone who knows both can see that someone who knows only one cannot. Use one concrete worked example that requires both.

At the end, tell me the single most common mistake people make when they try to apply one of these to the other, and what to watch for in my own thinking that would signal I am making it.
๐Ÿง  what patterns am I missing
Here is everything I currently understand about [topic]: [write out your actual mental model, messily, including the parts you are unsure about].

Do not correct me line by line. Instead, tell me what the underlying pattern is that my version is circling but not quite naming, and what the people who are genuinely good at this understand that my model does not include yet. Point at the structure, not the trivia.

Then tell me the one thing in my explanation that is subtly wrong rather than obviously wrong, because that is the one that will keep costing me. Explain why it is wrong and what the accurate version is.
๐Ÿ‘ฉโ€๐Ÿ’ป the teach-back test
I have just learned about [topic] and I want to find out whether I actually understand it or only recognise it. Test me properly.

Ask me to explain it back to you in my own words, then probe the weak spots in my explanation with follow-up questions rather than telling me the answers. Give me one applied scenario where I have to use the idea rather than describe it, and one case at the edge where the obvious answer is wrong.

When we are done, tell me honestly which parts I understand, which parts I am pattern-matching without understanding, and what I should go and read or try next to close that specific gap.

make it automatic

Turn the pack into a skill

Copying prompts out of a page works for about a week. A skill is a small folder holding your rules that Claude pulls in on its own when a request matches, so the behaviour becomes the default rather than something you have to remember.

  1. ๐Ÿง  Ask Claude to write it. No code involved. Paste the prompt below and it drafts the whole thing, including the description line that decides when it triggers.
  2. ๐Ÿ’ก Get it zipped. Ask Claude to package the result as a zipped folder with the SKILL.md inside. That folder is the skill.
  3. ๐ŸŒฑ Install it. In the Claude app: Customize, then Skills, then Add, then Upload a skill, and choose the zip. In Claude Code: drop the folder into ~/.claude/skills/. Custom skills work on every plan, Free included. Official steps: creating custom skills.
  4. ๐Ÿ‘ฉโ€๐Ÿ’ป Tune it after a week. If it pushes back when you wanted a quick answer, tell it so and have it edit the SKILL.md. Two rounds and it fits how you actually work.
๐ŸŒฑ build my thinking-partner skill
Build me a skill that changes how you respond when I bring you a decision, a plan or something I am trying to understand, so you make me think instead of thinking for me.

Write the SKILL.md. Give it a short lowercase hyphenated name (do not put "claude" or "anthropic" in the name, or the upload gets rejected) and a description that says clearly when to use it: whenever I ask what I should do, ask for a plan or strategy, or ask you to explain something I am learning. The instructions should tell you to ask me the questions that would change the answer before offering an opinion, to argue against the option I am leaning toward, to label your opinions as opinions so I can push back, and to hand the decision back to me rather than closing it.

Add an explicit exception so this does not get annoying: for straightforward tasks like formatting, drafting boilerplate, or a quick factual lookup, skip all of it and answer directly. Then package it as a zipped folder I can upload.

honest bit

When not to use any of this

๐Ÿ’ก These prompts are slower, and that is the point, but slower is only worth paying for on work that is genuinely yours to own: the decisions, the positioning, the things you will have to defend later. For real busywork, reformatting a doc, tidying a spreadsheet, writing boilerplate you would never read twice, let Claude do the whole thing with zero guilt. Turning every small task into a thinking exercise is its own kind of waste. Keep the muscle where it matters.
