What it does

Cover Skill is an agent skill from kangarooking/kangarooking-skills. Use for the owner's personal creator-content thumbnails and covers for short video, Bilibili, Douyin, WeChat, or similar platforms from a title, summary, established real portrait, kangaroo IP, product Logo, screenshot, or app reference. It enforces the owner's visual signature, runs a four-concept selection stage, then five responsive platform ratios. Do not use for generic clients, book or album covers, slide title pages, generic posters or social cards, article body illustrations, document headers, website…

Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 19 other files, including scripts, reference files and assets (for example `agents/openai.yaml`, `references/core-rules.md` and `references/exploration.md`).

It sits in Media & Creative, covering Social media graphics, Messaging and chat bots and Slides and decks. It works with Bilibili, Douyin and WeChat. The repository describes itself as: My custom AI Agent skills.

When your agent uses it

  • The owners personal creator-content thumbnails and covers for short video
  • Similar platforms from a title
  • Established real portrait
  • Generic clients

Example prompts

  • “/cover-skill”

Requirements

  • Python 3

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Four concepts
  2. Five ratios

What it can do on your machine

Read from SKILL.md and the folder at commit 08bbee0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cover Skill loads about 2.9k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 163 tokens; SKILL.md has 1,458 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~163
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~11k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,458 words (~2,852 tokens).

“Create high-attention covers for this creator while keeping the personal signature and quality bar consistent—not a fixed palette, font, texture, or layout. The validator assumes the personal signature applies.”
