Big Idea

The argument in one line.

Feeding an AI video model's own official prompting guide into a custom Claude skill turns any one-line idea into a fully-specified, shot-by-shot prompt without the user ever reading the guide.

Who This Is For

Read if. Skip if.

READ IF YOU ARE…
  • You generate AI video with Seedance 2.5 or a similar model and get inconsistent results from short, generic prompts.
  • You've heard of Claude skills but assumed building one required real coding ability.
  • You want a repeatable prompt template that matches a specific model's own best-practices documentation.
SKIP IF…
  • You don't use Claude or don't have access to Claude Skills.
  • You're looking for Seedance troubleshooting beyond prompt writing. This is prompt-crafting only.
TL;DR

The full version, fast.

Seedance 2.5 ships with an official 35-page prompt-adherence guide most users never read, and generic one-line prompts get inconsistent results because of it. The video builds a custom Claude skill by asking Claude itself how to make one, then uploading a PDF of the guide as the skill's source material. Once saved, typing a trigger phrase followed by a rough idea makes Claude auto-generate a fully-specified prompt: opening paragraph, timestamped shots, camera language, and consistency notes, all pulled from the official spec. The prompt then pastes directly into a Seedance 2.5 video generator. Any tool's documentation can become a personal Claude skill that encodes its rules into every future prompt.

Chapters

Where the time goes.

00:0000:45

01 · Cold open: the hidden Seedance guide

Opens on the AI-generated payoff clip, then reveals Seedance 2.5 ships with an official 35-page prompt-adherence guide almost no one reads.

00:4501:06

02 · What a Claude skill actually is

Defines a Claude skill in plain terms and previews folding the entire guide into one so Claude writes to spec automatically.

01:0601:44

03 · Community and course plug

Pitches his paid AI community as the source of ongoing tricks like this one.

01:4402:27

04 · The trigger-phrase demo

Types a one-line idea prefixed with a trigger phrase and shows Claude instantly return a fully structured, guide-compliant prompt.

02:2704:11

05 · Reading the generated prompt

Walks through the returned prompt's structure: opening paragraph, timestamped shots, and named camera angles pulled straight from the official guide.

04:1104:59

06 · Generating in Magnific

Pastes the prompt into Magnific's Seedance 2.5 video generator and renders the alien food-truck clip live.

04:5905:41

07 · Second demo: a simpler idea

Repeats the process with a shorter pickleball idea in a brand-new chat, showing the skill persists across conversations.

05:4106:15

08 · Why most people explain this wrong

Argues other creators sharing Claude skills either withhold the how or over-explain it technically, when asking Claude directly is enough.

06:1506:47

09 · Asking Claude to build the skill

Prompts Claude with a plain-language request to make a skill the easiest way possible, and gets back the exact file structure needed.

06:4708:16

10 · Feeding in the 35-page guide

A direct article link and a Google Doc link both fail to load; exporting the guide as a PDF and uploading it is what finally works.

08:1608:44

11 · Save vs. Update Skill

Explains the button changes from Save to Update Skill once the skill is active, and how to confirm it actually saved.

08:4410:24

12 · Locking the trigger phrase

Restricts the skill so it only fires on the exact trigger phrase, keeping normal Claude chats unaffected, then demonstrates renaming the trigger word.

10:2411:18

13 · Wrap-up and plugs

Recaps the result, then repeats the community and Magnific discount links before the standard subscribe ask.

Atomic Insights

Lines worth screenshotting.

  • Seedance 2.5 has an official 35-page prompt-adherence guide, and most people generating video with it have never read a page of it.
  • A Claude skill's bare minimum is one file: a SKILL.md with a YAML frontmatter block and markdown instructions underneath, no scripts or extra folders required.
  • You can ask Claude how to build a Claude skill, and it will generate the file, the structure, and the setup instructions for you.
  • Feeding a model's own prompt guide into a custom skill turns a five-word idea into a shot-by-shot prompt with camera angles, timestamps, and consistency notes.
  • Claude couldn't read a public Google Doc link directly. Exporting it as a PDF and uploading the file worked where the link failed.
  • Skills can be scoped to a trigger phrase, so typing a specific phrase before an idea activates the template while normal chat still works as expected.
  • A skill only takes effect after you explicitly save or update it. The button changes from Save to Update Skill once it's active.
  • The generated prompts name shot types explicitly (wide street-level, low angle, medium shot, close-up tracking) instead of leaving camera language to guesswork.
  • The same skill and trigger phrase work in a brand-new chat every time, since the skill lives at the account level, not inside one conversation.
  • Changing a skill's trigger phrase is just a follow-up chat instruction, followed by hitting Update Skill again to save the change.
Takeaway

Turn Any Tool's Guide Into a Skill

SKILL BUILDING

Feeding a tool's own documentation into a custom Claude skill, gated behind a trigger phrase, turns any short idea into output that follows that tool's exact rules.

01Cold open: the hidden Seedance guide
  • Seedance 2.5 has an official 35-page prompt-adherence guide, and most people generating video with it have never opened it.
  • Generic, one-line video prompts underperform against this specific model because the guide specifies structure the prompt needs to follow.
02What a Claude skill actually is
  • A Claude skill is a saved, reusable instruction set you call up on command, so Claude follows the same spec every time without you re-explaining it.
  • Folding an entire technical guide into a skill means you benefit from its rules without ever having to read the guide yourself.
04The trigger-phrase demo
  • Prefacing a prompt with a specific trigger phrase tells Claude which skill to apply, turning a five-word idea into a full spec instantly.
  • The trigger phrase has to come first in the message for the skill to recognize and activate it.
05Reading the generated prompt
  • A well-built skill returns a structured prompt: opening paragraph, timestamped shots, and named camera angles, not just expanded prose.
  • Naming camera moves explicitly, like wide street-level, low angle, or close-up tracking, is what separates a guide-compliant prompt from a generic one.
06Generating in Magnific
  • The output of a well-built skill is meant to be copied straight into the target tool with no manual editing required.
  • Selecting the correct model inside the target app before pasting is still a manual step the skill doesn't handle for you.
07Second demo: a simpler idea
  • A Claude skill persists across brand-new chats, since it's saved at the account level and not tied to one conversation.
  • The technique scales down to very short prompts too. Even a five-word idea gets expanded to the full spec.
08Why most people explain this wrong
  • When someone shares an AI trick without the how, or explains it in unnecessarily technical language, the fix is often just asking the AI directly.
  • AI tools are good at explaining their own setup process, often more clearly than a human tutorial, if you just ask them directly.
09Asking Claude to build the skill
  • Asking Claude how to make a skill the easiest way possible returns the exact minimum file structure needed, no separate documentation required.
  • The described minimum for a Claude skill is one file: a SKILL.md with a YAML frontmatter block and markdown instructions underneath.
10Feeding in the 35-page guide
  • A direct article link and a public Google Doc link both failed to load as skill source material.
  • Exporting the same document as a PDF and uploading the file directly worked when both link-based methods failed.
11Save vs. Update Skill
  • A skill only takes effect once you hit Save. After that, the same button becomes Update Skill, which confirms it saved and is live.
  • Confirming a skill saved correctly is as simple as checking whether the button now reads Update Skill instead of Save.
12Locking the trigger phrase
  • Restricting a skill to only activate on an exact trigger phrase, instead of every mention of the topic, is a one-line follow-up request.
  • Renaming a skill's trigger phrase is done conversationally too: state the new phrase, submit, then hit Update Skill to save the change.

Are all earth foods this good? Just wait for dessert. You're about to unlock the number one secret that no one shares.
How to create the absolute best Seed Dance 2.5 videos you've ever made.
Unlock the power of Seed Dance. And all you're gonna have to do is just just provide a generic basic description.
That's not landing again. Watch me. I'm gonna show you exactly how.
Unbelievable. It's the exact way you're supposed to prompt for Seed Dance 2.5 videos.
There is an actual prompt adherence protocol just for this model. A real dense 35 page guide.
You can't say it's not perfect because it's based 100% off of this 35 page article. This and you'll master c dance 2.5.
But here's the thing, I didn't actually read this guide and you won't have to either. You're going to build it into a Claude skill, and this skill creates the perfect prompt. But what's a Claude skill, bro?
A Claude skill is a set of instructions you can call up. So Claude writes to the perfect spec every time.
Now, most people think creating a Claude skill is way too technical, and don't get me wrong, it is. But here's the thing, it's not gonna be for you.
Because for you, I'm showing you the tricks and secrets the pros rarely share. We're gonna make AI do it all for us. And if you like learning tricks like this, making difficult strategies extremely easy, then you'll definitely want to join my new Let's AI school community.
Because this is where all the tricks like the one I'm showing you today live, and I add more and more to it almost every single day. If you're not in the Let's AI school community yet, you're literally just guessing. AI videos, AI images, prompt secrets the pros keep to themselves, it's all in there.
Check the link in the description, and here's the cheat code. In order to get a prompt that looks like this, this was all I said. You first preface it by saying c dance skill.
That automatically lets Claude know, let's get this rolling. We're gonna create the perfect prompt based off of this long c dance 2.5 guide.
All you have to do is present your idea. Now watch this. Let me show you this in real time, then I'm gonna show you exactly how to do this.
Here we go. Let's scroll down to the bottom, and let's come up with something just off the top of our head together right now. How about something out of the ordinary, extra creative, and unique?
A woman walks in New York City. It's midnight in Times Square. Bright lights and billboards surround her.
Now let's add something unique. Together and having fun.
Add dialogue, fun conversations. Right when I hit submit, look at the prompt we're about to get.
Now before we do, we have to put the most important part in the front. We're gonna say c dance skill just like this. That way, we're letting Claude know the kind of prompt that we want.
Because now watch this. It understands anytime you see c dance skill in any of my prompts. Look, it's crafting the perfect prompt.
Literally, you can't say it's not perfect because it's based 100% off of this 35 page article. The exact specifications and prompt inherent strategies from c dance themselves.
And now look at this. Look what we're gonna get. Prompt, copy, paste, ready.
You can see it is the exact format that we want. The opening paragraph. We get the time stamps.
In each of the time stamps, we get the director's shot, the wide street level shot, the low angle, the medium shot, the close-up tracking, thirty seconds, just like that. Watch this.
We're gonna head over into one of my favorite apps. We're gonna be in Magnific where we do have cdance 2.5 available. We're gonna go to video generator.
And now for the model, let's go ahead and select it. There it is. Cdance 2.5.
Now, if you don't have a subscription to Magnific yet, I highly recommend it. There's a link in my description to get an additional 20% off when you do sign up. Okay.
So here we are back in Magnific. Let's go ahead and paste this full prompt in. There it is.
Let's go ahead and generate this.
Longest day ever.
Oh, okay. Please don't probe me. Relax.
We come in peace and also hungry. Wait. You're actually kind of adorable.
We get that a lot. Okay. New best friends.
Pizza first. Pizza. Excellent choice, Earth.
This this changes everything. Wait till you try dumplings.
Are all earth foods this good? Just wait for dessert. Best midnight ever.
Same time tomorrow? Now, what I wanna do is come back over here in the Claude. Let's make this a little bit easier.
Now, this is gonna work in any chat. So watch this. If I go to a brand new chat, fresh.
Say this, c dance skill. Let's go even more basic. Okay.
We're gonna go simple. C dance skill, a man and woman playing an intense game of pickleball on a rooftop in Miami golden hour.
Again, add dialogue. Now with the full prompt there, let's go ahead and hit this submit button. Now right away, there we have it.
It's automatically coming up with the prompt. So here is the key question. How exactly did you train claw to do this?
Now, let me show you exactly how. But first, let's take a look at the prompt that we just got. Okay.
And now here it is. Here is the full prompt right here. This one's gonna be ten seconds.
Come back over in the Magnific. Let's now paste this one in, And since we do have a man and woman being referenced, we'll go ahead and add myself as the man, and we'll add in another influencer as the woman.
And now let's generate that one.
That's not landing again. Watch me.
Unbelievable. But now let me show you exactly how to do this. I see a lot of people sharing these clawed skills.
The difference is is that a lot of people don't tell you how they do it, or they will tell you how to do it, but they'll provide the instructions in a more technical way than is necessary. But here's the thing, we have AI for a reason, so why not leverage it? Now, I'm not saying that you can't make it any better.
Of course, when you become more advanced, maybe you do have a better way, but for the most part, Claude is using the exact guide and here's exactly how. Again, this is all you have to do.
Sometimes we make things a little bit too hard. Whenever you wanna know how to do something and leverage the power of Claude, just ask. Here's where we started.
How do you make a Claude skill the easiest way possible? Okay.
Instantly, it gives us the specific instruction. The bare minimum is generally just one file, a skill dot m d with a y a m l front matter block and some markdown instructions underneath.
Wait. What? I like how it follows up with that's it.
No scripts or extra folders. Well, for some people saying that's it, it's overwhelming. What even does that mean?
Again, no problem. Because even when you look the next step where it says the whole thing looks like this, if you're a beginner, you're like, I don't have any idea what this is.
No problem. Because here's what we're gonna do. Follow the instructions.
Again, because we said easiest way possible to get one made. Tell me what you want it to do and roughly when it should kick in. Hence, where I say c dance skill, that's when it knows it needs to kick in.
I will write the script for you and I'll package it into a dot skill file. You click save and install it. That's it.
Then I give it the instructions. I wanna create a skill based on this c dance 2.5 prompt guide.
Here's the link. Well, here's the thing. When you give it a link, it really couldn't read it because I tried one of two ways.
Now the first time I provided the link from the article itself. Now, if you want this full article, I'll include the link in the description. Okay?
So I took this full entire article right here. I then copied it and pasted it into a Google Doc, which is exactly what this link is at the very top. Well, again, it couldn't get access to the link even though it was public.
So I said, fine. I'll download the PDF, which is in fact what I did from Google Docs. I just exported the PDF.
Now I imported it in the cloud. Look. Here it is.
The whole 35 page guide. Immediately, it's doing everything for me. Now, I already saved it, but what's gonna happen is you're gonna get this prompt just like this.
You're gonna open it up. This is all you have to do. It gives you the full skill.
This is everything right here. Now what you would do instead of where it says right here update skill, before that it says save.
Okay? So once you select save, it's now gonna transform to update skill.
But here's the thing. At first, Claude was saying, every single time I mentioned c dance, it's gonna activate it. Well, what if I don't want it to?
What if I want some advice on c dance? I don't want it to just automatically start the prompting process.
So what I said is, is it possible only activate it when I say quote c dance skill followed by my instruction? That way, when I wanna use my existing frameworks, I can proceed as usual.
But if I say c dance skill, the I misspelled it, skill will be activated. Yes. Basically, easy change.
That's all you have to do. And then I selected update skill, and so I said, how exactly do we use it for clarification? So to use it, I can just open up a new chat and say the activation word and it will start.
Look. Yes. Open a fresh chat and start your message with c dance skill followed by whatever scene or instruction you want.
And that's exactly what we've been doing. Then I just asked a clarity question because I didn't know if I saved it. It didn't have access to it.
So I just went back up and I hit update skill again, which it already was. But that's all you have to do. If it says save skill, just make sure you hit save skill.
Once you do, it will now say update skill. That's how you know it's been saved. And now moving forward, anytime you say c dance skill or give it any certain word that you want.
I chose that specifically. You can just say in the instruction, you can actually type it down here in the message, change my activation word from c dance skill to c dance x y z, and then hit submit.
And then after you submit it, then you're gonna select update skill. That way any changes you make will then be saved. And I have to tell you, every time I've used this method, the prompts and videos turn out incredibly well.

The Hook

The bait, then the rug-pull.

Seedance 2.5 has an official 35-page guide dictating exactly how to prompt it, and almost nobody using the model has read it. This breakdown covers how one creator built a Claude skill that reads the guide for you, then auto-writes studio-grade prompts from a one-line idea.
