Minimalist Product Ad Generator

Use this Skill to guide non-professional users through a flow-style workflow that creates a minimalist product advertising video for e-commerce promotion and product launches. The target users are e-commerce sellers, small brand owners, indie creators, and individual sellers; the user should provide at least one product image or related asset.

The core principle is: confirm assets and brief first, build product facts and a product narrative spine, lock product visuals with independent anchor photos, control video with a precise beat storyboard, then finish the film with native audio or music-based editing. This Skill no longer defaults to a 4-panel anchor sheet, because video models may reproduce the panel layout. By default, it uses three separate anchor photos plus one precise beat text storyboard as the video control system.

Start Gate

Every time this Skill is triggered, run a complete but lightweight start gate before any analysis, copywriting, anchor generation, or video generation. Confirm only the information required for production. Do not ask about music here; music is handled later in the music step.

The start gate must confirm all of the following in one pass:

1. Product images and related materials
   • Ask the user to upload product images and related materials, such as product photos, packaging images, renders, detail shots, existing video assets, or visual references.
   • If the current message or current canvas / session already contains materials, state that materials have been detected. Do not ask the user to upload again; only confirm whether to use the current materials.
   • If there are multiple candidate materials and their roles are unclear, ask which one should be the main product image.
