media-model-router

[Responsibility boundary] Day 3 S4 dedicated to automatic model routing for advertising videos. Backend integration: Kling 3 (direct Higgsfield MCP) + Veo 3 · Seedance 2.0 (delegated via fal-gateway). Clearly distinguished from paired skills video-gen (general video generation) · image-gen (image-only) — differentiation keys are category-matrix-based automatic routing + suspicion-blocking hook pattern + generation of main/auxiliary video sets. Use this skill for requests such as: "Make an ad video", "main cut video", "automatic ad video generation", "Day3 S4 video", "suspicion-blocking hook video", "ecommerce ad video", "auxiliary 2-cut video", "Kling·Veo·Seedance routing". V6 Day3: ⑮ one main video 5–10 seconds + ⑯ two auxiliary cuts (Day3 S4 14:08–14:20 instructor demo, SPEC §3.1). [Internal materials] references/category-matrix.md: category matrix for instructor/development-team internal use. Do not expose to students (REQ-MEDIA-013). references/hook-pattern.md: analysis of the suspicion-blocking hook (internal).
