Varg Video Generation

What it does

When your agent uses it

• Creating videos
• Talking characters
• Social media content

Example prompts

• “/varg-video-generation”

Requirements

• A credential in FAL_KEY
• A credential in ELEVENLABS_API_KEY
• Compatibility (from SKILL.md): Requires bun runtime. FAL_KEY required. Optional ELEVENLABS_API_KEY, REPLICATE_API_TOKEN, GROQ_API_KEY
• Pre-approved tools (allowed-tools): Bash(bun:*), Bash(cat:*), Read, Write, Edit

Workflow steps

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

1. 1Onboarding (REQUIRED for new users)
2. 2Running Videos

What it can do on your machine

Read from SKILL.md and the folder at commit da4face. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash(bun:*)
  • Bash(cat:*)
  • Read
  • Write
  • Edit

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • bunx

  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):

  • fal.ai
  • elevenlabs.io
  • replicate.com
  • console.groq.com

  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
  • FAL_KEY
  • REPLICATE_API_TOKEN
  • GROQ_API_KEY

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

• Compatibility

  Requires bun runtime. FAL_KEY required. Optional ELEVENLABS_API_KEY, REPLICATE_API_TOKEN, GROQ_API_KEY

  From compatibility in the SKILL.md frontmatter.

Context cost

Varg Video Generation loads about 788 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 227 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~53

When it runs · the whole SKILL.md, loaded when a task matches

~788

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.

  3. Add to `.env` file in project root

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.
