Use when asked to polish, finish, ship, "make it feel done", or before a release.

Includes a built-in share safe-zone check — when a WeChat official account cover is shared to Moments, only the central 1:1 square is kept, and this Skill ensures the title is not cropped. Triggered when the user says "make a WeChat official account cover", "make a header image", "article lead image", "2.35:1 cover", "WeChat official account cover image", or "make a few cover versions".
Build the pre-migration spec of a website — pages, redirects, 404s, layout variants, the EDS blocks each page needs with reuse verdicts, dynamic features, martech and open decisions — as documented knowledge files for people and a migration agent. Use when someone asks to scope, estimate or plan a migration, wants "which pages use block X / which blocks does page Y need", a redirect or 404 inventory, or the facts behind a migration brief. Not the migration itself (replica, migrate, rollout)
Find missing interface and service states such as loading, empty, partial, permission, timeout, stale data, validation, failure, interruption, and recovery. Use when a designer asks what states or edge cases are missing from a screen, component, journey, or feature.
Converts a Stitch screen, a local HTML file, or a URL into clean, platform-agnostic HTML5 + CSS — semantic markup, CSS custom properties for theming, dark mode via prefers-color-scheme, mobile-first responsive, zero framework dependencies. Works in browsers, WebViews, Capacitor, and Ionic. Only the Stitch route needs an API key.
Conversational design ideation agent that researches trends, explores visual directions, and refines ideas through adaptive questioning — then produces a rich PRD document and auto-generates Stitch screens. Your design buddy that thinks deeply before designing.

Surgical aesthetic upgrade pipeline for existing React codebases. Takes ugly, functional code (Bootstrap defaults, generic Tailwind, amateur CSS) and transforms it to Awwwards-tier quality WITHOUT touching or breaking the underlying JavaScript logic - states, effects, API calls, event handlers, routing, and data flow are sacred and untouchable.
