Guided Promo Video

What it does

When your agent uses it

• Making brand-aligned promo
• Tasks that involve Video production
• Tasks that involve Brand strategy and identity

Example prompts

• “/guided-promo-video”

Requirements

• Node.js
• A credential in ELEVEN_LABS_API_KEY

Workflow steps

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

1. 1"Are we inside your brand's repository, or would you like to provide a URL (e.g. your marketing site) so I can research your brand online?"
2. 2"Would you like generated background music? If yes, you'll need an ELEVEN_LABS_API_KEY in your environment. You can get one at…

What it can do on your machine

Read from SKILL.md and the folder at commit 24c0d4b. 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

  No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript).

  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):

  • elevenlabs.io

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

• Credentials

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

  • ELEVEN_LABS_API_KEY

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

Context cost

Guided Promo Video loads about 1.3k tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 572 words of instructions outside code blocks.

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

~70

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

~1.3k

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

• NoteMentions a .env fileSKILL.md:24

  Do not attempt to read .env files or verify keys yourself.

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.
