Big Idea

The argument in one line.

The value of a more capable AI model isn't the model itself, it's having a ready list of specific prompts that turn raw capability into finished work across code, business planning, and daily productivity.

Who This Is For

Read if. Skip if.

READ IF YOU ARE…
  • You use Claude or a similar AI coding assistant regularly and want a stack of ready-to-copy prompts instead of starting from a blank chat.
  • You're a solo builder or 'vibe coder' who ships code without a dedicated security or QA process.
  • You're weighing whether to brainstorm a new business or side project with an AI assistant instead of a person.
  • You want a simple way to figure out which of your daily tasks could be automated or delegated to an AI agent.
SKIP IF…
  • You don't use Claude, Claude Code, or a comparable coding assistant — the prompts assume access to that specific tool.
  • You need rigorous, cited information about AI pricing policy — the cost details described are informal and specific to one model's promotional window.
  • You're looking for game-development tutorials beyond a single MCP integration name-drop.
TL;DR

The full version, fast.

The video announces the return of a Claude model (called 'Fable 5' throughout) after a temporary removal, explains its usage-based pricing (free up to 50% of quota, then API-rate billing), and warns it will fall back to a more conservative model for risky requests. The core content is eight copy-paste prompts: run a security-and-optimization code review over recent commits, use a browser-control extension to walk through your app like a real user and get a UX report, run an interview-style business-brainstorming session, schedule a recurring 24-hour security audit of API endpoints, connect an X/Twitter research tool to mine your own posts for business ideas, connect an Unreal Engine integration to build 3D games conversationally, and finally list out a day's tasks and ask the assistant how it could have automated them. The throughline is treating the assistant as a standing team member with recurring jobs, not a one-off chat.

Where the time goes.

00:0000:44

01 · Intro

Cold open declaring the model's return; sets up the promise of eight things to do with it.

00:4403:06

02 · Pricing

Explains the temporary 50%-usage promotional window through July 7th, the switch to API pricing after that, and a tighter security fallback to a more conservative model for risky requests.

03:0604:40

03 · Improving your code

Use case 1: run a review of all code written while the model was unavailable, looking for optimizations, gaps, and security issues.

04:4005:50

04 · Having it use Claude for Chrome

Use case 2: use a browser-control extension to have the assistant walk through the app like a real user and write a UX report.

05:5007:35

05 · Coming up with businesses

Use case 3: an interview-style business-consultant prompt that asks about skills, passions, assets, and goals before proposing SaaS/service/product ideas.

07:3509:23

06 · Security loops

Use case 4: a recurring 24-hour scheduled task that checks API endpoints for security holes, framed as a standing defense for vibe-coded apps.

09:2311:05

07 · X MCP

Use case 5: connecting a Twitter/X integration so the assistant can read the creator's own posts (and others') to surface business ideas and see how others are using the model.

11:0512:20

08 · Unreal MCP

Use case 6: a free Unreal Engine 5.8 integration that lets the assistant build and modify 3D game elements conversationally, pitched as a major upgrade over simpler web-based game libraries.

12:2014:21

09 · Automate your life

Use case 7 (framed as the final, most broadly useful tip): write down every task done in a day and ask the assistant how it could have automated or handled each one, called 'reverse prompting.'

Atomic Insights

Lines worth screenshotting.

  • A returned or upgraded AI model is only as useful as the specific prompts you already have queued up to run against it.
  • Scheduling a recurring security review of API endpoints turns a one-time audit into an ongoing safeguard instead of a task that gets forgotten.
  • The most common attack surface for hobbyist-built web apps is the API layer, not the frontend.
  • Interview-style prompting, where the assistant asks you questions one at a time before giving advice, produces more tailored output than asking for a plan up front.
  • Feeding an assistant your own social media post history turns writing you've already done into raw material for new project ideas.
  • Letting an AI agent operate a browser to click through your own product surfaces confusion points a developer is too familiar with the product to notice.
  • Writing down a full day's tasks and asking an assistant which ones it could have done is a low-effort way to discover automation opportunities you wouldn't think to ask about directly.
  • Treating code review as an ongoing habit after any model upgrade, rather than a one-time cleanup, catches quality gaps introduced while a stronger model was unavailable.
Takeaway

A capable AI model is only useful with a ready list of prompts

WHAT TO LEARN

The eight examples in this video share one underlying habit: turning a general-purpose assistant into a recurring worker with specific, repeatable jobs instead of a one-off chat window.

  • Running a code review pass after any tool upgrade catches quality or security gaps introduced while a weaker tool was in use, rather than assuming existing code is fine.
  • Letting an assistant operate a browser to walk through your own product like a first-time user surfaces confusion points that someone too familiar with the product would miss.
  • An interview-style prompt, where the assistant asks one question at a time before giving advice, produces more specific output than asking for recommendations immediately.
  • Turning a security check into a recurring scheduled task, rather than a one-time review, closes the gap where new vulnerabilities appear between manual audits.
  • Feeding an assistant your own past writing or social posts gives it concrete material to work from when generating new ideas, instead of relying on generic prompts.
  • Listing out a full day's completed tasks and asking what could have been automated surfaces delegation opportunities that are easy to miss when brainstorming from scratch.
Glossary

Terms worth knowing.

MCP (Model Context Protocol)
A connector standard that lets an AI assistant read from and act on an external service, such as a social media platform or game engine, instead of being limited to plain text chat.
Reverse prompting
Asking an AI assistant to review a list of tasks you already completed and suggest which ones it could have handled for you, rather than asking it to solve a problem you pose directly.
API pricing
A pay-per-use billing model, based on the amount of text sent and received, that applies once a subscription's included usage allowance is exhausted.

00:00The moment you've been waiting for happened, Claude Fable five is officially back. It is the greatest AI model. Nay, the greatest technology I've ever used in my entire life.
00:11It was taken away from us. It was ripped out of our hands, and it is finally back.
00:17You can now use it in Claude, Claude code, any platform that uses Claude, Cursor, everything, all of them is by you don't need me to convince you. You already know. It's the best technology ever made.
00:26It is by far the best model ever. I have the first eight things you need to do with Claude Fable five now that it is back. These eight things will help you get so much more out of it.
00:36If you feel like everyone else on the internet is getting tons of usage out of Fable five, you, this video is for you. But before we get into that, let's just go over the news and what the pricing is like now, what the usage is like now, how Claude Fable five will work moving forward. Check this out.
00:52You have 50% usage through July 7. What does that mean? You can use this model up to the first 50% of your usage.
01:01Once you're at 50% of your usage, then you have to pay API pricing just as a reminder. Claude Fable five is very expensive.
01:09So this will get very expensive once you used 50% of your usage with this model. You have to manually turn on extra usage if you wanna keep using it after that. That is a button in your settings.
01:21You turn that on. It basically allows you to deposit money, and that money is used as credits towards your extra usage. So it's API pricing.
01:29And then on top of that, there'll be much more tight security with Fable. Meaning, if you ask it to do things that are kinda iffy, hey.
01:37Hack this other government. Hey. Steal all the money from my friend.
01:40It'll be like, nuh-uh. We're falling back to Opus, and it will automatically switch to Opus for those tasks. My guess is it will be a little trigger happy with the security.
01:51It will fall back a little bit too often. You gotta imagine they're gonna be super careful now that the US government has cracked down on them. So that is kind of the bad news of all of this.
02:01Uh, you can use it a lot less. And if you use it more, it's very expensive. I will say this before we get into those eight big things you need to do the moment it releases, which is right now.
02:10Here's the story. I'm turning on extra usage. I'm going to deposit.
02:14I think it is, like, a thousand dollars. You can buy a thousand dollars worth of credits for $700. I'm going to take that deal because I think it is a pretty solid deal.
02:23Claude Fable five isn't just a step better than what the other models were before. It is a gargantuan step forward.
02:31And so the people that use Fable five will have an outrageous advantage against those who don't. So if you are building a business right now, if you're trying to earn revenue, you need every advantage you can get.
02:44So for me personally, I will be paying the API pricing for the extra usage. I think you should consider it too. I'm not sponsored by Claude.
02:51They're not paying me. No one from their team has ever reached out to me. I am not affiliated with their company in any sort of way, but Fable five is incredible, so I'll be paying the extra money.
03:00Now let's go into those eight use cases. What are those first eight things you should be doing now that Claude Fable five is back? These first two things I'm gonna go over is for those out there who vibe code, who build apps, who have been maybe vibe coding the last couple weeks.
03:13The first thing you wanna do is find exactly all the code you wrote the last couple weeks while Claude Fable has been gone and fix all of it. Opus is a great model. Don't get me wrong, but Fable is literally 10 times better.
03:25I mean, it's just so much better. So what you wanna be doing is and I will put all these prompts down below. Everything will be down below.
03:32Please check all the pool requests we merged the last two weeks. Do a code review. Find any optimizations or improvements we can make.
03:38I did this on Fable five on high. For code reviews like this, we're fine with high. We don't need to go to ultra code.
03:44Let's just stick with high for that. And then you hit enter on that. If you don't use proper GitHub best practices, you can just say, at all the code from the last two weeks that we wrote.
03:54It'll go through its memory and find all the changes it made. But you wanna make sure all non Fable code is found and improved and checked. Fable is so much better at writing code.
04:05The first thing you wanna do is fill any gaps, get out any optimized code, anything like that, any code that might have security issues. Use this.
04:14Put it in. It'll check the code. You're good to go.
04:16The second tip takes advantage of a feature not many people use, so this will be a good one to set up just for everything you do moving forward. And that taking advantage of the Claude for Chrome extension. Claude is amazing at browser use.
04:31It is amazing at controlling browse. And by the way, if you don't vibe code as much, you can just skip to the third lesson from here. We get into more general tasks.
04:37I wanna start a little bit with vibe coding first, but taking advantage of that Chrome extension. And so the prompt you wanna steal is this again down below. Walk through every major user path in the app you're building using browser control.
04:51Write a report on where users can get confused and what I can do to improve the UX. If you don't have the Chrome extension installed yet, just say, hey. How do I install the Chrome extension?
05:01It'll set it up for you. You just have to go into your settings. And then from there, what will happen is Fable will literally open up your browser, open up a new tab, and walk through whatever app you're building and test it like a real user would.
05:14Then it's gonna write a report. It's gonna tell you how you can improve the user experience, and it'll do it for you. Fable is the most human like model I've ever used, and using it in this way will get you such better improvements out of the user experience.
05:28I also like to just do all testing of all code I write this way. Anytime code's written, I'll go and say, hey. Now pop open a browser and test it for yourself.
05:36So this is a tip you wanna use over and over and over again inside Cloud Code. Just as a side note, this is Cloud Code for desktop. I think it's the best way to use Cloud Code.
05:43I think it's better than the CLI. Makes it really easy to manage all your sessions. So just a little side tip there.
05:49For this next use case you should be doing immediately, I switched over to the chat section of the Claude desktop app. I went in here Fable five high. This next one's going to help us figure out businesses we can create with Claude Fable.
06:02If you're looking to start a digital business much like I have, I have, like, eight or nine different businesses I started. Brainstorming with AI is one of the best ways to do it, and Claude Fable five is by far the best business planner I've ever talked to in my entire life. So what you wanna do is steal this prompt, and, again, I will put it down below for you so you can just copy and paste it in.
06:22But, what Fable five will do is act as a business consultant. He will figure out my goals, my ambitions, my priorities, what my passions are, what my audiences are, what my different assets are, what value I can provide to the Internet, and then come up with direct plans for what I can build to start making money online.
06:42If you're not making revenue online right now, you should at least be striving to get there. It allowed me to quit my job.
06:50I quit my job three years ago because of all my different business lines. My YouTube's blowing up. I have different SaaS, Creator Buddy, Henry Intelligent Machines.
06:59I have my community. All these are different things that I've built and brainstormed with AI, and you should be doing the exact same thing. I promise I'm nothing special about me.
07:07You can be doing it too. This is how you do it. Seal this prompt.
07:10What it will do is interview you question by question by question to understand you on a really deep level, and then it will give you precise recommendations about the products and services you can create to start making money online, start generating revenue.
07:25Even if it's just side revenue to your current job today, this will help you through it. FableVise is the best, like, business consultant planner I've ever talked to in my life. Steelist prompt is down below.
07:35Next, let's talk about looping. Looping is the topic of the day. Everyone's talking about looping.
07:41Inside of Claude code, you have a slash loop skill. The way this works is you can do slash loop. Give it a amount of time.
07:50So we're gonna do twenty four hours, and then we can give it a task to do every twenty four hours. So if you wanna do this every five minutes, you can do that. If you wanna do it every ten minutes, you can do that as well.
07:59But what we're going to do is because Fable is so good at security, we're going to make sure that our app is secure. So if you are a vibe coder, this is something you wanna do quite often.
08:12The biggest attack vector of vibe coded apps is API routes. And so one thing I've been doing that is really helpful here is if you do slash loop twenty four hours.
08:23You can say, check out our API endpoints and make sure they are secure. And now every twenty four hours when I hit enter on this, Fable will go in and loop through every single API endpoint in our app and make sure they're not hackable, make sure no one can get in, delete data from your database, or anything like that.
08:45If you are vibe coding anything right now, this is security practice. You a 100% wanna do do slash loop. Give it whatever time period you want.
08:53For this, I'm gonna do once a day just because Fable is so expensive. And we're gonna say check out our API endpoints and make sure they are secure. Now we have an agent that's like protector, our Batman of the app or vibe coding to make sure our app and all our API endpoints are very secure.
09:09It's the reason why my app creator buddy hasn't had a a single security incident in the year and a half it's been out is because I'm constantly having agents pound the API endpoints and find any security issues that might be going around. The next thing I'd want you to do is take advantage of the XMCP. If you use Twitter slash x at all, this is an amazing, amazing tool I've been using recently.
09:31I'll put a link down for this down below if you wanna use it. This has been an amazing tool for customer research. So, basically, the XMCP works is it allows Claude and Fable to actually go in and look at your tweets, look at your posts, search for other people's posts.
09:48It basically just gives it access to all of Twitter. And so me, as a business creator, I like to go in and see based on my tweets and based on other people's tweets, what are other businesses I can start?
10:02What are other apps I can build to solve their challenges? So if you take the link to XMCP below, you give it to Claude Code, you give it to Fable and say, hey.
10:11Set this up. It'll walk you through setup. You then can do interesting things like, say, look at my last 100 posts and let me know five SaaS ideas I could build out based on my strengths and interests.
10:22So if you tweet on Twitter and you got a bunch of tweets, they are good data in context you can feed into your Claude code agent to figure out apps to build out. This is an awesome one. Take the link down below from XMCP.
10:36There's so many other things you can do here as well. You can even say search through X, find other use cases people are doing with Claude Fable, and let me know the top five use cases of Claude Fable. And that will go and kinda crowdsource what everyone's doing with Claude Fable, which is really awesome as well.
10:52Set that up. It's an ultra valuable tool for everything you're doing. Claude, you can just deposit a couple bucks in the XMCP accounts.
10:58You can pull a ton of different posts, and you can use that as data for everything you build, which is really, really sick. The next use case you can do is really cool if you are a nerd like me and enjoy building video games. If you're one of those people that were building a bunch of really cool three JS games, that's like the first thing you do with every new model that comes out.
11:18I have an upgrade for you, which is the unreal 5.8 MCP. This is completely free.
11:24This allows you to build really, really sick games using Unreal Engine, which is just, like, a 100 times better than three JS. It's completely free. It plugs into Claude code.
11:36And if you use Claude Fable, it's just, like, 10,000 times better at building games. You can just go in and say, hey. Build me this in the game.
11:45Make the guy do this. Give it this gun. Make it shoot this.
11:47And Claude code will go in and add all those things to the three d game you're building. Obviously, this just looks like a 100 times better than anything you get in Three. Js.
11:57If you're a nerd and you've experiments around with building games inside Claude Code and maybe use weaker libraries like Three. Js, you wanna upgrade, try out Unreal 5.8 m three. It's the first, like, major video game engine that you can connect to Claude Code and Claude Fable and actually use it to build games directly without any technical knowledge at all.
12:15So this was a really fun one. I'll leave the link down below for Unreal MCP as well. And this last one is great if you just don't know how to get the most out of these models.
12:25And this is an exercise I have everyone do that I work with. And that is write down every task you do today. Every single task, write it down on a piece of paper.
12:35Use a pen and paper. As you walk around your apartment, your house, whatever it is, write down your task, put them on a piece of paper. I have, like, my 20 different tasks I'm doing today here.
12:45Then you go into Claude. You go into Fable. You list every single task you did that day, whether it's checking emails, responding to things, building things, whatever it is.
12:55You put it in, and then you ask Claude Fable, take a look at my tasks I did today. How can I use you to better handle, automate, and complete these tasks? How could you be the most service to me and save me as much time as possible?
13:08You hit enter. This is what I call reverse prompting, asking the agent what it can do for you. Fable will then go and figure out how it can save you the most time, automate your tasks, do the most work possible for you.
13:20Everyone should continuously be doing reverse prompting exercises like this every single day to discover new things the agent can be doing for you. I don't care if you're at work. You put in all your tasks that you're doing at work.
13:33This will help you figure out how to automate and handle as as much of your life as humanly possible. Reverse prompt. I'll take this.
13:39I'll put this down below. All the prompts or all these things are down below. Just copy, paste, take whatever you want.
13:45Fable five is back. Take advantage of this. Make sure to use as much of this free credit they're giving you for the next week as possible.
13:53You should be disappointing yourself if this weekend and you didn't use your 50% of your usage. It's such an incredible technology. It's such amazing time to be alive.
14:03I am so grateful. If you learn anything at all, leave a like, subscribe, turn notifications. I'm gonna do a live full boot camp this Friday on Claude Fable five inside the Vibe Coding Academy.
