The first 3 seconds = Life or death for your video"The [thing] that [surprising claim]..."
"What [expert/celebrity] doesn't want you to know about..."
"I discovered something about [topic] that changes everything..."
"There's a reason why [common belief] is completely wrong...""[Common advice] is actually making things worse..."
"Stop [doing X] immediately. Here's why..."
"Everything you know about [topic] is wrong..."
"This is the [worst/best] advice I've ever heard...""This is how I [achieved result] in [timeframe]..."
"Before vs After: What [X days/weeks] of [thing] looks like..."
"I went from [bad state] to [good state] by doing this one thing..."
"Watch what happens when I [do thing]...""Wait, don't scroll yet..."
"Okay hear me out..."
"I know this sounds crazy but..."
"You're not going to believe this...""If you're [specific situation], this is for you..."
"The reason you're not [getting result] is probably this..."
"[Specific audience], stop what you're doing..."
"You've been [doing X] wrong your whole life...""So there I was, [dramatic situation]..."
"This is the craziest thing that's ever happened to me..."
"I need to tell you about what happened when..."

"We need to talk about [common problem]...""What would you do if [scenario]?"
"Have you ever wondered why [thing]?"
"Can you guess what [thing] costs?"
"Which one would you choose?"More time to build curiosity:
- Can use 5-15 second hooks
- Setup + Payoff preview works well
- Credibility establishment helps
Example:
"In 7 years of [expertise], I've never seen anything like this.
What I'm about to show you completely changed how I [do thing],
and by the end of this video, you'll know exactly how to do it too."ULTRA-FAST hooks (1-3 seconds):
- First word/frame must hook
- Text on screen essential
- Visual hook + Audio hook together
Example:
[TEXT ON SCREEN: "The $3 thing that replaced my $300 product"]
[VOICEOVER: "Throw away your expensive [product]"]
[VISUAL: Dramatic product reveal or reaction]Slightly more polished feel:
- Aesthetic matters more
- Hook can be visual-first
- Trending audio helps
Example:
[VISUAL: Stunning transformation or result]
[TEXT: "Wait for it..."]
[AUDIO: Trending sound that builds anticipation]- "Is the [Product] actually worth [Price]? Let me show you..."
- "I spent [X days] testing this so you don't have to..."
- "The feature [Brand] doesn't advertise but should..."
- "Why I'm returning my [Product] after [timeframe]..."- "The [thing] nobody teaches you about [topic]..."

- "The exercise you're doing that's actually hurting you..."
- "Forget everything you know about [fitness topic]..."
- "This [quick thing] burns more calories than [long thing]..."- "I found a glitch that [amazing result]..."
- "This strategy is actually broken..."

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +18 percentage points is the difference between those two pass rates over the 22 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
