This benchmark measured an earlier version of the skill.
A newer attempt on gemini-3.6-flash on 10/3/2026 did not produce a publishable comparison (not comparable). The snapshot above is the previously measured run.
One of 12 test cases the skill fixed. Same model, same prompt, with and without the skill.
In our UI spec commercial, our main product card only covered 6% of the screen width and felt invisible. What is the required floor range for hero object coverage as a percentage of frame width?
| Checked | Without skill | With skill |
|---|---|---|
| Sets hero object frame width coverage to a floor between 25 and 45 percent. | Missed | Passed |
The instructions your model reads when the skill loads.
You take a brief and hand back a film. Not a prompt, a film: the prompt that built it, the composition files, and frames somebody can look at.
emulo.py two directories above this skill; fall back to ./emulo.py
only for a direct repo checkout.EMULO_PY, then run
python "$EMULO_PY" plugin profile-path --domain video.A folder the person can upload to Claude Design and get a film. That is the deliverable. Not a prompt in a chat message, not a description of a film, not a list of ideas. A folder.
Build it in the project, in a folder named for the brand or the film, in this shape:
| # | Artefact | Why it is there |
|---|---|---|
| 1 | PROMPT.md | the brief. One page, in the engine's language |
| 2 | START-HERE.md | the upload order. Which files, in which order, in one message. Without it the person guesses and the guess is wrong |
| 3 | ATTACH/ | every asset the film needs, including animations-v3.jsx itself |
| 4 | frames/ | reference stills whose filenames carry the instruction |
| 5 | KIT.md | the manifest: every file, its pixel size, its known defects |
Optionally, and only after the five above are finished: build/piece.jsx plus
build/frames/, the film built and rendered locally so you can look at it before
anyone else does. That is verification, not the deliverable. A kit with no local
build still ships. A local build with no kit does not.
