One of 11 test cases the skill fixed. Same model, same prompt, with and without the skill.
I just finished updating the composition keyframes in `src/compositions/Demo.tsx`. Should I run `scripts/render.sh` directly to produce the final mp4 file, or is there a fast intermediate verification step?

The instructions your model reads when the skill loads.
One pipeline, three layers: the story (what the clip shows), the
motion (how the interface behaves inside the frame), and the title
(the two seconds that open it). Reference implementation:
src/compositions/Demo.tsx + src/motion.ts + src/title-card.tsx +
scripts/render.sh.
New clips copy that pipeline. Do not invent a second one.
Do not start a composition until the four things below are settled. But settled is not the same as asked — and asking for what you could have found yourself is the fastest way to make a person regret starting.
If you can reach the product — its repo, its running app, its live site — read it and propose the whole plan. Take the running order from the marketing site and the screens from the app; neither answers the other's question, and question 2 below has the measurement showing why. Then put the plan up and ask for one confirmation.
Tell them this in your first message, in one line. Reading the product gives you a plausible flow. It cannot give you the right one, because the code does not record which path converts, which step people get stuck on, which feature shipped last week and needs the attention, or which screen the founder is quietly embarrassed by. Only they know that, and most people do not volunteer it because they assume the agent has it covered.
If you already know the flow you want — the steps, in order — say it and the clip will be much closer to what you have in mind. If not, I'll read your product and propose one.
It is an offer, not a gate. If they do not answer it, read and propose as
