The Greatest AI Ever. Fable 5 is back.
However, since it can be used within the subscription plan only until July 7th...
'How you use it during this period' will greatly affect your work productivity for the next few months.
It's a serious waste to use it for light questions. I'll explain 5 'heavy tasks' I'm giving to Fable 5.
I'll also provide the full version of the prompt I actually use at the end. ↓
▫️How to Maximize Fable 5's Capabilities
Since its revival on July 1st, Pro / Max / Team plan users can use Fable 5 for up to 50% of their weekly usage limit until July 7th. After that, it's expected to switch to a pay-as-you-go system (usage credits).
In other words, this is practically the only week you can use it to your heart's content for a flat fee.
Moreover, Fable 5 consumes limits faster than normal models.
If you use it for light small talk, your precious quota will melt away in an instant.
Fable 5's true strength isn't just clever answers, but
'Long-duration autonomous work.'
Complex design. Organizing messy operations. Skill creation, automation, and QA.
It can complete heavy tasks that would take a human a full day without giving up halfway.
This is what makes it exceptional.
That's why I'm having Fable 5 rebuild the 'business foundation' that will continue to be effective even after July 8th.
It's about creating a state where the AI can run the work on its own without needing instructions from scratch every time.
I've narrowed down what to do by the 7th into five points.
Finally, I'll give you the full version of the business improvement prompt I actually use, so please read while saving it.
① Show all current operations and have it perform an inventory
The first thing to do isn't automation. It's an inventory.
Daily tasks. Weekly tasks. Tasks that are a bit tedious every time. Tasks where you explain the same thing over and over.
Throw all of these to Fable 5 and have it organize them.
The point is not to say 'automate this' right away.
First, have it categorize 'what is the input, what is the process, what is the output, and where is human judgment necessary.'
I also failed at first by jumping straight into automation. If you leave it to AI without visualizing the business, you'll just mass-produce things that are off-target.
It's plain, but this becomes the foundation for everything.
② Have it clean up accumulated Skills and prompts
For those using Claude Code or Codex, you've probably noticed prompts and Skills (work procedures taught to the AI) increasing before you know it.
We also realized we had over 20 Skills, and honestly, it looked like this:
- Multiple similar Skills exist.
- Old prompts remain.
- Don't know which one to call.
- Output quality fluctuates every time.
Have Fable 5 organize all of this.
'Read all current Skills, consolidate duplicates, supplement missing steps, and fix them into an easy-to-use format.'
That's it.
This isn't for a one-time deliverable; it's maintenance that affects all future AI work. Fable 5's long-duration work capability is best utilized in these 'read everything and fix it' type tasks.
③ Challenge the automations you gave up on in the past once more
Personally, this is what I want you to do most.
- Gave up because of errors halfway through.
- Couldn't finish because the specifications were complex.
- Quality didn't stabilize no matter how many times it was fixed.
Everyone has at least one of these 'shelved automations.'
Throw that to Fable 5 one more time.
At this time, changing how you throw it is important.
Instead of 'fix this script,' say:
'I want to reduce this task. Think of the optimal method, and if necessary, create Skills, checklists, and mini-tools.'
Hand it over as a whole. Things that were impossible with previous models might just be completed normally. I've had several production-related automations that were stuck start moving because of this.
④ Rebuild deliverables as a 'single flow' rather than 'standalone'
AI can make LPs. It can make slides. It can write LINE messages.
But what's needed for work isn't a standalone deliverable.
- Get interest with an X post.
- Have them apply via an LP.
- Convince them with seminar slides.
- Give them a final push with a LINE message.
If this flow isn't connected, it won't become a deliverable that leads to sales.
So, I prompt Fable 5 like this:
'From product information, design a consistent production flow from X posts, LPs, slides, to LINE messages. Separate the parts to be left to AI and the parts for human confirmation.'
What can be made with AI and what can be used in business are different. Don't stop at 'making' with Fable 5; have it create a 'state that runs in practice.' This is where the biggest difference is made.
⑤ Finally, have it perform QA
Things made with AI are most dangerous the moment they are made.
It looks like it's working, but it gets stuck when used in practice. This happens often.
So finally, always have Fable 5 itself check what was made.
Look for things like these:
- Does it stop when input is insufficient?
- Is the output format stable every time?
- Is there a risk of misposting, missending, or file destruction?
- Are the points humans should check clear?
You don't have to aim for full automation. Semi-automation that doesn't cause accidents is overwhelmingly stronger in practice.
Humans look at the final 5%. Have the AI create the checklist that makes that 5% easy to see. This is the form that runs best on the ground.
I'll give you the prompt I actually use
I've created a business improvement prompt that lets you do all five of these at once.
It's a long prompt where Fable 5 proceeds all at once from business inventory to identifying 15 improvement ideas, prioritizing, implementing Skills/checklists/mini-tools, and final QA and reporting.
Honestly, I think just using this will be worth it before July 7th.
1You are an AI that combines the roles of a Business Improvement Architect, AI Automation Engineer, Skill Designer, and QA Lead.23Your goal is to analyze my current operations and use Fable 5's long-term thinking and implementation capabilities to significantly reduce my future workload.45Do not stop at light brainstorming; if necessary, create Skills, prompts, templates, checklists, mini-web apps, scripts, automation flows, and operational rules.67Premise:8- I want to utilize AI in my business.9- However, I haven't fully organized what to automate, which Skills to create, or where to start improving.10- I want you to think from the perspective of "how my current business should be AI-fied."11- Always confirm before performing dangerous operations, destructive operations, handling credentials, external posting, or operations that incur costs.1213First, ask me the following questions.14If there are parts you can proceed with by estimation even without an answer, please do so.15161. What are my main business tasks?172. What tasks do I repeat daily/weekly?183. Which tasks take a lot of time?194. What have I given up on automating in the past?205. What deliverables do I often create?216. What tools, files, folders, MCPs, APIs, and external services do I use?227. Ideally, what state do I want to be in eventually?2324After that, proceed in the following order:2526STEP 1: Create a Business Map27- Organize into daily, weekly, monthly, and one-off tasks.28- Create a table of inputs, processes, outputs, tools used, and common bottlenecks.29- Separate judgments humans should make from tasks that can be left to AI.3031STEP 2: Propose Automation/Efficiency Candidates32Provide at least 15 improvement ideas from the following perspectives:33- Skills that can be made immediately34- Improvements to existing Skills35- MCP/plugin integration36- Standardized prompting37- Checklist creation38- Mini-web app creation39- Spreadsheet/CSV processing40- Semi-automation of posting/delivery/document creation41- Debugging/QA automation42- File organization/naming/storage rule maintenance43- Knowledge search/summarization/reuse4445Evaluate each candidate in the following format:46- Improvement Idea:47- Problem it solves:48- Expected effect:49- What to create:50- Implementation difficulty:51- Time required:52- Risk:53- Priority:5455STEP 3: Determine Priorities56Categorize improvement ideas into the following three:571.

Summary
Fable 5 is available for a flat fee only until July 7th.
What you should do this week isn't testing its cleverness, but
Showing it your current business, having it think about what to automate, having it create necessary Skills and tools, and finally having it perform QA.
The answers will disappear, but the foundation will remain.
If this was even slightly helpful, please like and save.
