What it does

Yuv Viral Video is an agent skill from hoodini/ai-agents-skills. Edit any selfie or screen-share footage into a viral short-form video in YUV.AI's signature style — Apple-style liquid-glass cards (real CSS backdrop-filter), dark-mode polish, MrBeast-paced cuts, video-title karaoke captions, premium GSAP motion graphics, no fake content, never covering the speaker's face. Hebrew is rendered in Rubik Black, English in Anton uppercase. Always renders BOTH 9:16 and 16:9 and always saves with V<N suffix for backups. Trigger when the user drops a path to an .mp4/.mov/.mkv and says…

Its SKILL.md is about 7.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 21 other files, including scripts, reference files and assets (for example `README.md`, `references/setup.md` and `scripts/apple_glass.py`).

It sits in Media & Creative, covering Motion graphics, Transcription and Web animation and motion. It works with GSAP and HeyGen. The repository describes itself as: 🧠 AI Agent Skills Repository - A curated collection of specialized skills for AI coding agents (Claude Code, GitHub Copilot, Cursor, Windsurf). Created by Yuval Avidani using…

When your agent uses it

  • The user drops a path to an .mp4/.mov/.mkv and says edit this
  • Turn this into a short
  • Any Hebrew equivalent (ערוך סרטון
  • Podcast-only audio edits

Example prompts

  • “edit this”
  • “make it viral”
  • “turn this into a short”
  • “/yuv-viral-video”

Requirements

  • Python 3
  • A credential in ELEVENLABS_API_KEY

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Per-glyph font routing — Anton handles Latin, Rubik Black handles Hebrew. The single font-family: 'Anton', 'Rubik', sans-serif declaration…
  2. RTL containers — every Hebrew caption line gets dir="rtl" on its container. English brand tokens stay LTR within the same line via the…
  3. Brand-name spelling in Hebrew — Yuval's preferred Hebrew transliterations
  4. Companion catalog has bilingual EN/HE everywhere — the live catalog flips entire UI to Hebrew on toggle (see effects.yuv.ai). The same…

What it can do on your machine

Read from SKILL.md and the folder at commit f7a43d8. 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 10 files in scripts/ (Python, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • python
    • ffmpeg
    • npx

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

  • Network

    Links to these hosts (documentation or services it may open):

    • effects.yuv.ai

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • ELEVENLABS_API_KEY

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

Context cost

Yuv Viral Video loads about 7.5k tokens when it runs, and up to ~8.5k if it reads all its reference files. Until then it costs about 221 tokens; SKILL.md has 3,265 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~221
When it runs · the whole SKILL.md, loaded when a task matches
~7.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.5k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:36
    ABS_API_KEY` from `~/Developer/video-use/.env`. Set it once and both skills work. Do not duplicate the key in this skill

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 3,265 words (~7,465 tokens).
