Turns product photos into AI video shots that keep the product identical: a lock sheet (fixed geometry, fixed surface, allowed motion), a reference pack of 2-4 angles passed as @image roles to Seedance 2.5 or Kling 4, a camera-risk ladder (locked frame → push-in → slide → small orbit), banned motion words, one action per 4-6 s shot, a drift check with varg video_analyze, and the real packshot composited back where text must be exact. Fixes the #1 "looks fake" tell in AI product ads: warped…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Keep the product identical in every AI shot AI video models redraw the product in every frame. With one photo they guess the hidden sides, and long, soft or printed products drift: wedges turn into blocks, labels melt, cans invent a back. This skill locks the product before any clip is generated and checks every clip after. Generation runs on varg: REST `https://api.varg.ai/v2` (the `varg-ai` skill) or the MCP server `https://mcp.varg.ai/mcp`. ## 1. Write the lock sheet (one per product) ``` PRODUCT: car seat gap filler, single piece FIXED GEOMETRY: long thin wedge, ~50 cm long, ~4 cm wide at the top, tapering; seatbelt slot near one end FIXED SURFACE: black leather-like cover, contrast stitching along the top edge, no logo ALLOWED MOTION: held, slid into a gap, objects dropped on top; never bent, squeezed or rotated fast NEVER: boxy, shorter, glossy, another color, a second slot ``` Separate geometry, surface and motion; never mix an old and a new label in the references ([seedance.tv](https://www.seedance.tv/blog/how-to-keep-product-shape-consistent-in-ai-video-ads)). ## 2. Build the reference pack | Ref | What | How | |---|---|---| …

How to install
mdr add varghq/skills/varg-product-lock@sha256:2d1b6832b918f2cdThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
