What it does

Style Library is an agent skill from nateherkai/hyperframes-student-kit. Select, customize, or extend the project's reusable motion-graphics card library and style templates. Use for choosing a visual style, adding a card, building a new style pack, or reusing a template in a HyperFrames video.

Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Motion graphics. It works with HeyGen. The repository describes itself as: Edit videos, reels, and YouTube Shorts with Codex or Claude Code. 14 skills, transcript-driven cuts, storytelling, 406 motion-graphics cards, and HyperFrames templates.

When your agent uses it

  • Choosing a visual style
  • Building a new style pack
  • Reusing a template in a HyperFrames video

Example prompts

  • “/style-library”

What it can do on your machine

Read from SKILL.md and the folder at commit 0d30152. 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

    Shell commands in SKILL.md call:

    • node

    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

Style Library loads about 401 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 184 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~401

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); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 184 words (~401 tokens).

“Read style-library/GUIDE.md, then style-library/registry.json. Filter by style, tier, and purpose before opening individual cards. Read the selected style's DESIGN.md, tokens.css, and manifest slot limits.”
