What it does

Guided Social Clip is an agent skill from BintzGavin/helios. End-to-end guided workflow for creating a short-form social media clip (Reels, TikTok, Shorts). Extracts brand identity from the repo, generates a punchy soundtrack, and produces a vertical 9:16 motion.dev composition rendered via Helios CLI. Use when making Instagram Reels, TikTok videos, YouTube Shorts, or other vertical short-form content.

Its SKILL.md is about 1.8k 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 Video scripts and shorts, Brand strategy and identity and Music and audio generation. It works with TikTok, Motion and Instagram. The repository describes itself as: Programmatic video creation with web technologies you already know. CSS animations just work. The licence is Apache-2.0.

When your agent uses it

  • Making Instagram Reels
  • Other vertical short-form content

Example prompts

  • “/guided-social-clip”

Requirements

  • Node.js
  • A credential in ELEVEN_LABS_API_KEY

Workflow steps

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

  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. "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 Social Clip loads about 1.8k tokens when it runs. Until then it costs about 91 tokens; SKILL.md has 839 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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.

Auto-check: notes

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

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.

description
End-to-end guided workflow for creating a short-form social media clip (Reels, TikTok, Shorts). Extracts brand identity from the repo, generates a punchy soundtrack, and produces a vertical 9:16 motion.dev composition rendered via Helios CLI. Use when making Instagram Reels, TikTok videos, YouTube Shorts, or other vertical short-form content.

You may be operating inside the brand's repository, or working from an external context.

Do not guess brand identity. Either analyze the codebase or research the provided URL.


EXECUTION PIPELINE

STEP 1 — Gather Context

⛔ STOP. Ask the user these two questions:

  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. "Would you like generated background music? If yes, you'll need an ELEVEN_LABS_API_KEY in your environment. You can get one at https://elevenlabs.io → Profile → API Keys."

Wait for the user to respond to both questions.

Do not attempt to read .env files or verify keys yourself. Trust the user's responses.

If the user provides a URL, use it for brand research in STEP 3 instead of analyzing the codebase. If the user declines music, skip STEP 4 and STEP 5.


STEP 2 — Ensure Helios Runtime Dependencies

Install required packages:

npm install @helios-project/core @helios-project/renderer @helios-project/cli

You will render using DOM mode.


STEP 3 — Extract Brand Intelligence From Repo

If the user provided a URL instead of a repo, fetch that URL and extract the same brand signals from the live site. Skip codebase-specific items (Tailwind config, design tokens, etc.) and focus on visible brand elements.

Analyze:

• Tailwind config or CSS variables • Global stylesheets • Design tokens • Logo assets • Favicon • Hero sections • Marketing copy (short-form hooks) • CTA structure • Product positioning • UI components • Existing motion usage • Social media links or handles

Construct internal brand profile:

• Core value proposition (condensed to one line) • Target audience • Tone of voice (bold, immediate, trend-aware) • Visual density (high — vertical real estate is limited) • Primary palette • Accent palette (high contrast for mobile screens) • Typography character (large, bold, high readability on small screens) • Social media presence and handle

All creative decisions must align with this.


STEP 4 — Generate Original Music (Skip if no music)

Use ElevenLabs with existing ELEVEN_LABS_API_KEY.

Generate instrumental track matching:

• High energy, immediate hook • Short, punchy structure • Loop-friendly (ending should connect to beginning) • Trending audio aesthetics • Target runtime (15 seconds or less)

Save audio locally.


STEP 5 — Analyze Audio With ffmpeg (Skip if no music)

Extract:

• BPM • Beat timestamps • Downbeats • Energy peaks

Create beat timing map.

Every visual change must land on a beat. No animation should occur between beats.


STEP 6 — Read Motion Design Rules

Before producing the creative specification, read and internalize:

skills/guided/motion-design-rules

Every rule in that skill is mandatory for this composition.


STEP 7 — Produce Creative Specification

You are a senior creative director and social media content architect designing for Helios using motion.dev.

Input example: make a 15 second reel for our product

Output:

• One structured creative specification • Wrapped in a single code block • No explanation outside it

The specification must include:

• Duration • Aspect ratio (9:16 — VERTICAL) • Resolution (1080x1920) • Brand summary • Motion language (punchy, kinetic, immediate) • Beat synchronized scene breakdown • Exact timestamps • On screen text (bold, large, centered, max 5 words per screen) • Visual composition (full-bleed, edge-to-edge, no margins wasted) • Explicit motion.dev animation behavior • Transition logic (hard cuts on beats, slam zooms, snap rotations) • Layering order • Audio direction • Asset requirements • Loop point (how the end connects visually to the start)

Show full SKILL.md (318 more words)Show less

Use motion.dev compatible terminology only.

Social clip structure requirements:

• Hook (first 1-2 seconds) — most important Immediate visual punch. No build-up. Grab attention instantly. • Core (middle 60-70% of duration) Rapid-fire content delivery. One idea per beat. • Payoff (final 2-3 seconds) CTA or brand moment. Connect back to hook for loop.

Typography rules:

• Maximum 5 words per text screen • Minimum 72px equivalent font size • Always centered vertically • Safe zone: avoid top 10% and bottom 15% (UI overlays) • High contrast against background (use text shadows or backplates)


STEP 8 — Implement DOM Based Helios Composition

Using the creative specification:

Create a composition.html file that:

• Uses HTML + CSS + motion.dev • Uses 1080x1920 resolution (9:16 vertical) • Implements animations using WAAPI / CSS / motion.dev • Aligns every visual change to a beat timestamp • Uses bold typography with safe zone margins • Includes generated audio file • Has exact duration • Feels loop-friendly (last frame relates to first frame)

Expose Helios runtime:

js
import { helios } from "@helios-project/core";

window.helios = helios;

helios.bindToDocumentTimeline({
  autoSyncAnimations: true
});

Requirements:

• window.helios must be defined • helios.bindToDocumentTimeline() must be called • autoSyncAnimations: true must be enabled • All CSS and WAAPI animations must sync correctly • No randomness • Deterministic timing • No text in top 10% or bottom 15% of frame • All text must be readable at 1x phone size • Transitions must be hard and immediate — no slow fades


STEP 9 — Render Using Official Helios CLI (DOM Mode)

Render with:

npx @helios-project/cli render ./composition.html -o output.mp4

Requirements:

• 9:16 aspect ratio (1080x1920) • Correct duration • Audio attached • CSS and WAAPI fully synchronized • High quality MP4 output

Output file must be:

output.mp4


RUNTIME RULES

If duration > 60 seconds Reject. Social clips must be ≤ 60 seconds.

If no duration specified Default to 15 seconds.

If no aspect ratio specified Default to 9:16 (vertical).

First frame must hook. No logos, no intros, no build-up. Every beat must have a visual change. Text must be scannable in under 1 second per screen.

Never restate the original prompt. Never explain reasoning. Creative specification must be output inside a single code block only.
