Viral Youtube Shortsvyralcontent/content-skillsWrite and diagnose YouTube Shorts that hold attention on the Shorts Feed and route viewers into your long-form. Use when someone wants a shorts script, a shorts hook tuned for VVSA and the first 3 seconds, a fix for a flopping short, a read on whether to link a short to a long-form video, or a plan to build the shorts to long form funnel for their channel. Covers what the youtube shorts algorithm rewards now that the Shorts feed runs separately from long-form, how shorts retention is measured, and the youtube shorts strategy choices that move RPM (licensed music split, Creator Pool math, Engaged Views). Pattern-based viral shorts guidance grounded in how shorts tend to perform.010Virtual Listspatternsdev/skillsTeaches virtual list (windowing) techniques for rendering large datasets. Use when rendering lists or tables with hundreds or thousands of items that cause scroll jank or slow initial render.01Visa Debugleokemp223/embed-ai-tool当需要调试 GPIB/USB/TCP/Serial VISA 仪器通信时使用，支持 SCPI 命令收发、波形捕获、截图和持续监控。04Visa Doc Translateaffaan-m/eccビザ申請書類（画像）を英語に翻訳し、原文と翻訳を含むバイリンガルPDFを作成する02Visionkunchenguid/vision>03Vision Analysisminimax-ai/skills>01Vision Frameworkdpearson2699/swift-ios-skillsImplement computer vision features including text recognition (OCR), face detection, barcode scanning, image segmentation, object tracking, and document scanning in iOS apps. Covers both the modern Swift-native Vision API (iOS 18+) and legacy VNRequest patterns, VisionKit DataScannerViewController for live camera scanning, and CoreMLRequest/VNCoreMLRequest for custom model inference. Use when adding OCR, barcode scanning, face detection, or custom Core ML model inference with Vision.04Vision Multimodalthelobbi/claudeVision and multimodal capabilities for Claude including image analysis, PDF processing, and document understanding. Activate for image input, base64 encoding, multiple images, and visual analysis.01Vision Sftwshobson/agentsFine-tune vision-language models (VLMs) with supervised learning on image+text data. Use when adapting a VLM to a visual domain or task, configuring frozen-vision-tower LoRA, or debugging a VLM fine-tune that trains without learning.02Vision Supportpenfick/skills为非多模态模型（如 deepseek-v4-pro、GLM-5.1、mimo-v2.5-pro 等纯文本模型）提供图片识别能力。当主模型无法识别图片、用户发送了截图/设计稿/UI 截图需要分析、或者用户说'看看这张图'、'分析这个截图'、'这张图片有什么问题'时，自动触发此技能。也适用于用户粘贴了图片但当前模型不支持图片输入的任何场景。支持同时识别多张图片，通过配置多个识图模型实现主备回退。使用指令 /skill:vision-support 或 /vision 也可手动触发。铁律：本技能配置的模型仅用于图片内容识别，绝不参与主逻辑推理。注意：如果当前模型本身是多模态模型（如 Claude Sonnet 4、GPT-4o、Gemini 等可以直接识图的模型），不要使用此技能，直接让主模型识别即可。013Visionos Design Guidelinesehmo/platform-design-skillsApple Human Interface Guidelines for Apple Vision Pro. Use when building spatial computing apps, implementing eye/hand input, or designing immersive experiences. Triggers on tasks involving visionOS, RealityKit, spatial UI, or mixed reality.04Visualnick-vels/velsvisualГенерация фото, видео и аудио через VelsVisual CLI и KIE API (kie.ai). Используй, когда пользователь просит «сгенерируй картинку/изображение/фото/видео/музыку/песню/озвучку/голос/саунд-эффект», text-to-image, image-to-video, TTS или апскейл изображения.01Visual Contentkostja94/marketing-skillsWhen the user wants to plan, create, or repurpose visual content (images, infographics, social post images) across channels. Also use when the user mentions "content images," "social media images," "infographic," "visual content," "post image," "image specs," "visual repurposing," "content visuals," or "image for social post." For Pinterest, use pinterest-posts.01Visual Design Foundationswshobson/agentsApply typography, color theory, spacing systems, and iconography principles to create cohesive visual designs. Use when establishing design tokens, building style guides, or improving visual hierarchy and consistency.04Visual Design System Extractorsrinitude/skillsUse when reference images, screenshots, moodboards, style frames, brand boards, cinematic stills, product interface shots, or a live site URL must become a production design system, design tokens, art direction, motion rules, or a YAML style specification. Covers reverse engineering visual references into a deterministic YAML contract with graded confidence, evidence boundaries, and typefaces drawn from the live Google Fonts catalog and ranked as rarely used. Not for generating images or for ordinary frontend work where no reference has to be decoded first.091Visual Edit Precisionwshobson/agents>-01Visual Emphasis And Hierarchydembrandt/dembrandt-skillsThe most important actions and content in a UI should be visually prominent — through size, colour, weight, and position. Visual hierarchy guides the user's eye to what matters most and signals which action is primary. Use when designing button groups, CTAs, dashboards, cards, or any layout where actions or content have different importance levels.01Visual Explainernicobailon/visual-explainerGenerate self-contained HTML visual explanations for systems, code changes, plans, data, and technical concepts. Use for diagrams, architecture overviews, diff or plan reviews, project recaps, comparison tables, slide decks, and other visual explanations.027Visual Formatsmotion-team/creative-strategy-skillsA reference library of 45+ visual ad formats for Meta and paid social, each with a definition, funnel stage guidance, and medium (video/static/both). Use this whenever choosing how an ad should look and feel, building out a creative concept, writing a creative brief, or deciding which format best serves a messaging angle and awareness stage. Trigger when the user asks "what format should this be," "how should we execute this," "give me concept ideas," or any time a creative concept needs a production structure. Always pair with creative-mechanics to fully flesh out the concept — format defines the vessel, mechanic defines the cognitive move inside it. Either can come first; they work in both directions.01Visual Hierarchyowl-listener/designer-skillsEstablish hierarchy through size, weight, colour, spacing, and position so the eye lands in the intended order. Use when composing new work. For judging an existing screen, use `critique-visual-hierarchy` (visual-critique).01Visual Moderemotion-dev/remotionGuidance for working on Remotion Studio Visual Mode, sequence identity, node paths, symbolicated stacks, override IDs, and hot reload behavior. Use when implementing or debugging visual editing of Sequences.01Visual Novelgamedev-skills/awesome-gamedev-agent-skills>02Visual Planbuilderio/skills>-08Visual QAdylanfeltus/skillsUse vision models to self-review screenshots against design intent. Catches spacing issues, alignment problems, color inconsistencies, responsive bugs, and accessibility gaps. Use when reviewing designs, comparing implementations to mockups, or doing pre-ship QA.02Visual QA Testingspencerpauly/awesome-cursor-skillsVisually QA a web application by launching it in Cursor's built-in browser, taking screenshots, checking console errors, and auditing network requests. Use after making UI changes to verify they look correct.01Visual Recapbuilderio/skills>-05Visual Regression Testingaj-geddes/useful-ai-prompts>09Visual Stylecalesthio/openmontage|016Visual Testingpetrkindlmann/qa-skills>-02Visual Verdictyeachan-heo/oh-my-claudecodeStructured visual QA verdict for screenshot-to-reference comparisons01Visualizescaccogatto/okf-skills>-02Viteantfu/skillsVite build tool configuration, plugin API, SSR, and Vite 8 Rolldown migration.
