SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides an automated cover-engineering workflow to generate and select platform-ready cover images for social content, with a robust three-tier fallback to ensure a cover is produced even when the original image is missing.

Core Features & Use Cases

  • Supports platform-specific output schemas for WeChat (thumbMediaId with crop_multi), XHS (cover index), and Twitter (og:image).
  • Implements a three-tier fallback: user-provided cover → first image from body → image-generation with placeholder fallback.
  • Useful for design teams and content creators who publish on social platforms and require consistent, brand-aligned covers with minimal manual intervention.

Quick Start

Provide a title and content, and specify the target platform; CoverArtist will generate a platform-ready cover following the fallback rules.

FAQPage Schema
How do I automate cover generation for social posts across WeChat, XHS, and Twitter?▼

Automate cover generation by providing a title, content, and target platform to generate platform-ready outputs like WeChat thumbMediaId, XHS cover index, and Twitter og:image, ensuring functional schema compliance.

What happens to social media cover generation when the original image is missing?▼

When the original image is missing, cover generation uses a deterministic three-tier fallback: it selects a user-provided cover, then the first body image, then triggers an image-generation placeholder fallback.

Does cover generation support WeChat crop_multi schema and XHS cover index output?▼

Cover generation supports platform-specific schemas, directly meeting functional requirements for WeChat crop_multi and thumbMediaId, alongside XHS cover index and Twitter og:image outputs.

How do I start generating platform-ready covers with a fallback workflow?▼

Start generating platform-ready covers by providing your content title, body text, and specifying the target platform; the workflow applies its three-stage fallback to produce a compliant cover automatically.

Can I use body images as a fallback for platform-specific cover outputs?▼

Yes, you can use body images as a fallback; if no user-provided cover exists, the workflow automatically extracts the first image from the body content to fulfill platform-specific cover requirements.

What is the best way to ensure brand-aligned covers with minimal manual intervention?▼

The best way to ensure brand-aligned covers with minimal manual intervention is using an automated cover-engineering workflow that applies a deterministic three-stage fallback across social platforms.
