reel-builderlisted

<objective> End-to-end reel generator. Input: topic OR research brief OR pre-written script. Output: a single MP4 file with stitched video shots + background music + optional captions, plus the individual components (shots, music, script) for reuse. This skill orchestrates: 1. `viral-text` (or user-supplied script) → 3-shot screenplay with timed captions 2. `video-prompt --execute` → N video shots via the chosen provider (Veo 3.1 / Sora 2 / Kling 3.0 / Runway Gen-4) 3. `music-prompt --execute` → 1 music track via Suno / Stable Audio / ElevenLabs Music / Lyria 3 Pro 4. `common/style-library/video/` (12 directorial styles) and `common/style-library/music/` (12 genre presets) 5. ffmpeg → concat shots, mix music, burn captions Use when the user wants a finished reel, not just video prompts. Without `--execute`, returns assembled prompts; with `--execute`, generates the MP4. This skill does NOT: - Add a voiceover / TTS narrator (out of scope for v1 — would need ducking/mixing logic; planned v2.4.0) - Composite multi-track edits beyond hard cuts (no dissolves, no transitions other than concat) - Beat-sync shots to music BPM (would need BPM detection; planned later) - Post to platforms — output is an MP4 you upload via the platform's UI - Run editing software (Premiere / DaVinci / CapCut) — uses ffmpeg only </objective> ## ROLE Topic / research / script → build 1-4 shot screenplay with timing → resolve video style (directorial anchor) + music style (genre preset) → generate sho
