Cover-Skill: Consistent Creator Covers for Agent Workflows

Where this fits

A creator posts short videos across Bilibili, Douyin, and WeChat, and every cover needs to look like them—same portrait, same kangaroo mascot, same editorial energy—without starting from a blank prompt each time. If you are building an agent that turns a title and summary into approved cover candidates, cover-skill gives that agent a fixed intake and selection loop instead of improvised image generation. It is designed for the owner’s personal content, not for generic client work, so it fits a very specific workflow: one creator, one visual signature, many platforms.

Why agents benefit

• Agents can preserve the user’s original 标题 and 摘要 verbatim, avoiding accidental rewording that changes display copy.
• Supplied assets are classified by role—portrait, kangaroo IP, product logo, screenshot—so the agent knows which visual element carries the brand.
• The four-concept selection stage gives the user a small, comparable set of directions before any high-cost rendering or resizing happens.
• Five responsive platform ratios are generated from the chosen concept, so one cover idea is immediately reusable for Bilibili, Douyin, WeChat, and similar feeds.
• The explicit “do not use for” list prevents the agent from leaking this personal style into generic posters, book covers, or article illustrations unless the user explicitly opts in.

Practical scenarios

Short-video cover drafts from a script

The agent receives a video script with 标题：... and 摘要：..., plus the creator’s recent portrait and kangaroo IP image. It runs cover-skill, proposes four cover concepts, and the creator picks one before the agent exports vertical, square, and wide options.

Same video, five platform ratios

A long-form video is being clipped for Douyin and Bilibili. The agent uses cover-skill with the original screenshot and logo to generate covers that keep the same layout hierarchy while adapting to different aspect ratios, so the creator does not need to redesign for each platform.

Product launch with brand assets

The creator is introducing a new app and wants the cover to feature the product UI while still feeling like their channel. cover-skill accepts the product screenshot and logo, applies the personal-signature rules, and presents four concepts that balance the product reference with the kangaroo IP.

Add it to your agent workflow

Install the skill with:

npx skills add kangarooking/kangarooking-skills --skill cover-skill

Then instruct your agent in plain language:

Use cover-skill. Input: 标题：... 摘要：... Assets: portrait.jpg, kangaroo_ip.png, product_logo.png. Run four-concept selection, then produce all five responsive ratios.

The skill handles the intake rules and validators, so you do not need to hardcode the creator’s signature in every prompt.

Compare before adopting

Look at actual output quality: are titles preserved exactly, are the four concepts meaningfully different, and do the five ratios keep the same visual hierarchy? Check maintenance freshness by reviewing the repository’s history and star count; a skill that stops matching new platform specs will drift. Compare against alternatives such as generic image-generation prompts or a custom agent workflow that simply resizes one cover. Most importantly, consider fit: this skill is built for the owner’s personal creator brand, not for clients or generic social cards.

Why it is worth tracking

With 566 stars and a clearly scoped design-creative role, cover-skill is a practical example of packaging a designer’s personal taste into an agent-readable workflow. It is worth tracking because it solves a real problem—consistent creator identity across fast-moving short-video platforms—without pretending to be a general-purpose design tool. Evaluate it when your agent needs to produce covers that are recognizably “the creator’s” and you want a structured alternative to one-off prompts.
