What problem does it solve? Creating a visually consistent WeChat official account article cover normally requires manual design work in separate tools. This Skill turns a frozen article title, summary, and theme design spec into a ready-to-screenshot 900x383 horizontal cover page, keeping typography, layout, and theme decoration in one deterministic HTML deliverable. ## Core Features & Use Cases - Spec-driven cover generation: Reads cover-visual-input.json, cover-theme-snapshot.json, and cover-theme-design-spec.md to produce a single .page HTML file with inline CSS and inline SVG only. - Built-in visual references: Ships layout, visual contract, and component-mapping references that enforce safe zones, visual hierarchy, and truthful text usage without fabricating issue numbers or data. - Chunked single-agent writing: Writes the cover via a begin/append/finish/final sequence so the raw HTML/CSS is saved deterministically for Chromium screenshot rendering. - Use Case: Given an article about AI industry trends with a frozen title and summary, generate a themed 900x383 cover with a network-node visual system, brand line, and date, ready for screenshot delivery as the article cover. ## Quick Start Ask the agent to generate the article cover visual from the prepared cover input files and theme design spec in the workspace.
