What it does

Guided Testimonial Video is an agent skill from BintzGavin/helios. End-to-end guided workflow for creating a social proof or testimonial video. Extracts brand identity from the repo, generates a warm soundtrack, and produces a trust-building motion.dev composition rendered via Helios CLI. Use when making customer testimonial, review highlight, or social proof videos.

Its SKILL.md is about 1.7k 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 Marketing & SEO, covering Marketing psychology, Brand strategy and identity and Music and audio generation. It works with Motion. 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 customer testimonial
  • Review highlight
  • Social proof videos

Example prompts

  • “/guided-testimonial-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. "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 Testimonial Video loads about 1.7k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 777 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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.

description
End-to-end guided workflow for creating a social proof or testimonial video. Extracts brand identity from the repo, generates a warm soundtrack, and produces a trust-building motion.dev composition rendered via Helios CLI. Use when making customer testimonial, review highlight, or social proof videos.

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 • Testimonial sections or components • Review/rating displays • Customer logos or partner sections • Trust badges or certification marks • Social proof patterns (counters, stats, logos) • Marketing copy and value propositions • CTA structure

Construct internal brand profile:

• Core value proposition • Target audience • Tone of voice (warm, authentic, trustworthy) • Visual density • Primary palette • Accent palette (warm tones for trust) • Typography character • Social proof strategy (quotes, stats, logos, or combination)

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:

• Warm, uplifting tone • Gentle build to emotional peak • Inspiring but not aggressive • Target runtime

Save audio locally.


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

Extract:

• BPM • Beat timestamps • Downbeats • Energy peaks

Create beat timing map.

Quote reveals must land on downbeats. Name/title reveals should align to 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 brand trust architect designing for Helios using motion.dev.

Input example: make a 30 second testimonial video

Output:

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

The specification must include:

• Duration • Aspect ratio (16:9) • Brand summary • Motion language (warm, elegant, deliberate) • Beat synchronized scene breakdown • Exact timestamps • Voiceover (optional — may use text-only approach) • On screen text (quotes, attribution, stats, CTA) • Visual composition (quote cards, avatars, star ratings, customer logos) • Explicit motion.dev animation behavior • Transition logic (gentle fades, soft slides, subtle scale) • Layering order (background texture → quote card → avatar/photo → attribution → stats) • Audio direction • Asset requirements • Typography hierarchy (quote text large, attribution smaller, stats prominent)

Show full SKILL.md (270 more words)Show less

Use motion.dev compatible terminology only.

Testimonial structure requirements:

• Opening brand moment or context setter (2-3 seconds) • Quote 1: Full quote with attribution • Quote 2: Full quote with attribution (if duration allows) • Social proof stats (numbers, ratings, customer count) • Closing CTA with brand mark

Each quote segment: • Quote text animates in (typewriter or fade-in by line) • Brief pause for reading • Attribution appears (name, title, company) • Optional: customer company logo or avatar


STEP 8 — Implement DOM Based Helios Composition

Using the creative specification:

Create a composition.html file that:

• Uses HTML + CSS + motion.dev • Implements animations using WAAPI / CSS / motion.dev • Aligns quote reveals to downbeats • Uses elegant quote card typography • Includes quotation mark decorative elements • Includes generated audio file • Has exact duration

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 • Quotes must remain readable for minimum 4 seconds each • Star ratings should animate sequentially


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

Render with:

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

Requirements:

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

Output file must be:

output.mp4


RUNTIME RULES

If duration ≤ 15 seconds Show 1 quote + 1 stat + CTA. Prioritize the strongest quote.

If no duration specified Default to 30 seconds.

Maximum 3 quotes for any duration. Quotes must be real or representative — never fabricate. If no testimonials exist in the repo, use placeholder structure with clear labels.

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