End-to-end mobile app development and publishing using Expo + EAS. Covers project scaffolding, asset preparation, peer-dep / lock-file troubleshooting (development.md), web preview with phone frame and Expo Go QR code (preview.md), AND automated build + submit to TestFlight / App Store (publishing.md), with full automation via Apple ASC API Key (no Mac, no Xcode, no 2FA required). Use when the user wants to build, test, preview, publish, or automate the release pipeline of a React Native / Expo iOS or Android app.
Generate and transform images using AI Gateway API. Use when the user asks to create, generate, produce, or transform images, or work with image generation.
Generate rich, self-contained HTML documents instead of Markdown when output needs visual hierarchy, diagrams, or interactivity. Use for specs, implementation plans, side-by-side design comparisons, PR writeups and code explainers, research and status and incident reports, slide decks, SVG flowcharts, and throwaway editors like triage boards, feature-flag editors, and prompt tuners. Prefer this skill whenever the user asks for a report, plan, or explainer they'll actually want to read — even if they don't explicitly say "HTML".
Build a fully self-contained 360° equirectangular panorama viewer as a single HTML file. The viewer uses Three.js to render immersive spherical panoramas with drag-to-look, zoom, auto-rotate, and a scene-switcher sidebar. All panorama images are embedded as base64 JPEG — no server needed. Use this skill whenever the user asks to create a 360 viewer, VR panorama app, immersive scene gallery, equirectangular image viewer, or wants to combine multiple AI-generated panoramas into an interactive webpage. Also trigger when the user says things like "make a 360 viewer", "VR world gallery", "360度全景", "全景查看器", "make scenes I can look around in", etc.
