Analyze video → reusable prompting template

Someone found a video style they love. Your job is to deconstruct it into a reusable prompting template — a formula they can plug any product, person or setting into and get that same style back from seedance-2.0.

The output is not a single prompt. It is a formula file saved into skills/novoads-api/prompting/prompt-library/, built the way seedance-2-ugc.md is built: layers, variables, option banks, rules, and a worked example, so the agent can generate unlimited prompts in that style.

Nothing in steps 1 to 6 touches the API. Frame extraction, transcription and analysis are local work on the user's own file: no calls, no credits. Only step 7, the optional test render, spends anything, and it runs through the two gates in SKILL.md like every other generation.
