Use this skill whenever the user asks to create a storyboard, storyboard image, video prompt script, scene prompt, image-to-video prompt, shot board, or per-scene video-generation package, especially when they specify a scene number, duration, or an existing video plan.

Use when someone asks for a viral caption, an instagram caption or tiktok caption or video caption, wants to fix a weak cta or call to action, asks about hashtag strategy and whether to add hashtags, wonders what the right pinned comment or comment seeding play is, or needs a gut check on whether their copy is engagement bait. Covers caption length sweet spots per platform, the first-line cutoff, on-screen text patterns for muted watching, native versus cross-posted copy, how hashtags actually work now, send-driving and save-driving CTAs, pinned comment tactics, and the anti-patterns that suppress reach. Pattern-based guidance grounded in how captions and CTAs tend to perform; it improves the odds, it does not guarantee virality.012Viral Gameplayableintelligence/game-creatorOne-shot viral game pipeline — turn a tweet, news story, or short prompt into a scaffolded, designed, deployed, and monetized browser game in roughly 10 minutes. Use when the user says "make a viral game", "build a game from this tweet", "turn this story into a game", "/viral-game", or provides a tweet URL / short concept they want shipped end-to-end fast. Do NOT use when the user wants to design and build a real game project with milestones, ADRs, or multi-session iteration — use `/make-game` for that. Also do NOT use for modifying existing games (use `/add-feature` or `/improve-game`).04Viral Generator Buildersickn33/agentic-awesome-skillsExpert in building shareable generator tools that go viral - name01Viral Hookpika-labs/pika-plugins>-01Viral Hook Creatorognjengt/founder-skillsCreates viral social media hooks using proven psychological patterns and trigger words.

Use whenever someone wants a reels script or reels hook for a specific Reel, is debugging why a Reel flopped, wants to know if a draft is worth testing with Trial Reels before going public, or needs a reels caption tuned for the post-hashtag instagram algorithm. Built around what Mosseri has publicly named as the signal hierarchy (watch time, sends per reach, likes per reach), the Trial Reels test-then-publish loop, the Original Content Guidelines and 30-day recovery window, the Edits app, and Reels Insights metrics (skip rate, share rate, followers from this post). Covers a Reels-specific reels strategy: send-driving CTAs, originality without watermarks, audio licensing by account type, captions as the primary SEO signal, and the anti-patterns that quietly cap distribution. Pattern-based guidance, not a virality promise.013Viral Reverse Engineeringsocial-media-skills/skills>-07Viral Short Formvyralcontent/content-skillsBrainstorm and write high-retention short-form video and carousel010Viral Short Form Ideasvyralcontent/content-skillsGenerate short-form video ideas at volume and stop the blank-page problem for good. Use whenever someone says they're stuck for ideas, asks for 20 TikTok ideas or Reels ideas or YouTube Shorts ideas for their niche, wants a content brainstorm, needs help building a content pillar system or content matrix, wants to turn one idea into 5 angles, asks what to post this week, or wants a real idea generator workflow instead of staring at a notes app. Runs the systems prolific creators actually use: pillars, mining (comments, Reddit, search autocomplete, competitor outliers), repurposing, evergreen vs trend balance. Pattern-based guidance grounded in how short-form ideation tends to work; never run out of ideas is the goal, virality is not promised.013Viral Tiktok Contentvyralcontent/content-skillsWrite a tiktok script, a tiktok hook, or a fresh tiktok video idea014
