Use when designing, scripting, or iterating on a YouTube Short or vertical short-form video. Use when writing a hook, choosing music, deciding when to reveal a payoff, planning a climax, evaluating a draft short before publishing, or figuring out why a short feels weak.
Knowledge base for designing YouTube Shorts that retain viewers. Distilled from analysis of viral shorts and the techniques top creators use to consistently blow up.
This skill is knowledge for designing, not a tool for analyzing already-published analytics. Load it into context when planning or refining a short.
Every successful short is a single line from left to right:
HOOK ─────── PROGRESSION ─────── CLIMAX
(0-5s) (middle) (final beats)
Also called HPC — Hook, Progression, Climax. Every design decision should make this line flatter on the retention graph. Retention is the only metric that matters: the algorithm rewards high-retention shorts and almost nothing else.
Every short falls into one of two categories. The category determines design rules.
| Type | Engine | Music type | Examples |
|---|---|---|---|
| Payoff videos | Tension building toward a climax | Rising music with a synced beat drop | "Snowball fight in the desert", "Two Starbucks beef" |
| Emotion videos | Sustained strong emotion | Ambient mood-matching music | A wholesome gym moment, a satisfying cook |
Pick ONE per short. Mixing them dilutes both.
Run every draft against this checklist before publishing. If any answer is "no," pull up the matching reference file.

If you take only one thing from this skill, take this:
Build maximum tension, then save the reveal for the final beat.
