What you get

  • A 1080×1920 MP4 promo with its own beat-synced music, or 1080×1080 or 1920×1080 with their own layouts
  • An original soundtrack with an impact on the offer, a whoosh per card and ticks on every price, synthesised on your machine, with nothing to license
  • 2 to 4 product cards with 3D products in six shapes, labelled with your brand, or your own cut-out photos in the same light
  • Hang tags that strike the old price and flip the new one in, using only the prices you give
  • A tear-off promo-code ticket stamped with your end date, and an end card with your shop address and button
  • A brief checker that refuses an old price without a new one or one that is not higher, and a pasteable PROMPT.md for Claude Code or Codex
  • Open-source licenses for every part it builds on

Good fit

  • A shop announcing a weekend sale, a seasonal drop or intro prices on Reels, TikTok or Shorts.
  • A brand pushing a promo code with a clear end date.
  • A small store without packshots that still wants products on screen, or one with cut-out photos.

Not for

  • More than 4 products: make a second short
  • Product photos of your own without a cut-out PNG: the 3D shapes stand in
  • Prices worked out for you: it shows only the prices you give
  • Vocals or a licensed hit song, since the music is synthesised

About this skill

A promo short for a sale, a product drop or a promo code, with its own original soundtrack. The event opens as a poster, the offer smashes in as a giant rubber-stamped slab, then 2 to 4 product cards fly in on the beat, each with its product modelled and lit in 3D (a bottle, jar, candle, tin, mug or sneaker box) or your own cut-out photo, and a hang tag that strikes the old price and flips the new one in on a split-flap board. A promo-code ticket tears off its stub and the end date is stamped on, and the brand lands on the music's final hit over a stepped shop display of every product.

Example request

Make a sale promo short for our weekend sale: 30% off, four products with their old and new prices, our member code, ending Sunday, with the shop link at the end.

FAQ

Will it work out my sale prices?

No. Every old price, new price, discount, code and date comes from you as you write it. The brief checker refuses an old price without a new one, or an old price that is not higher than the new one.

Can I use my own product photos?

Yes. Cut each product out to a PNG with a transparent background and name it in the brief; it stands in the same studio light with a real shadow and replaces the 3D model.

How long does it take to render?

The short runs 12 to 19 s. The 3D products need WebGL, so a render is quick with a graphics card and much slower on a machine that falls back to software rendering.

Which agents is Sale Drop Short written for?

Any agent that reads SKILL.md folders, including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode.

Do I own what I make with it?

Yes. Everything your agent makes with this skill is yours, including for client and commercial work.

What if it doesn’t work for me?

Email support@lookbk.dev within 7 days of buying and we’ll fix it or refund you.
