What is faceless-explainer?

A workflow for turning written material into a faceless explainer video, using invented typography, diagrams, abstract graphics, and data visuals instead of filmed footage or a captured website.

Use it for topic explainers, concept breakdowns, how-to videos, and listicles built scene by scene in HyperFrames.

It helps create a teaching video when the source is only an article, notes, topic, or brief and there is no product footage to use.

faceless-explainer — Skill for Claude Code by heygen-com/hyperframes

About the project

HyperFrames is an open-source framework that turns HTML, CSS, media, and timed animations into deterministic MP4 videos. It is used locally, by coding agents, and in hosted authoring workflows to create rendered videos from web-based designs. Its catalogue add-ons provide skills, agents, instructions, hooks, settings, and a plugin for agent-driven video production.

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00098	$0.06856
Opus 5.5	$0.00039	$0.02742

Security

Grade A, and why

faceless-explainer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 22 executable files (scripts/assemble-index.mjs, scripts/assemble-index.test.mjs, scripts/audio.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plugin installs: Before setup or freshness commands, follow plugin execution rules when this skill is inside a HyperFrames plugin. Standalone installs keep the update instructions below.

First, keep this skill fresh — confirm with the user before running: npx hyperframes skills update faceless-explainer. A fast no-op when everything is current; otherwise it refreshes this skill plus the core domain skills it depends on before you rely on them.

media-use: Before sourcing audio/images/logos, call /media-use to resolve BGM/SFX/images from the HeyGen catalog and brand logos from their official sources. Run --adopt first to register existing assets. See /media-use skill. When the host app provides its own music or sound-effect tools, use those for music and sound effects.

Faceless Explainer to HyperFrames

Use this skill to turn a body of text into an explainer video: pick a design system, plan a teaching story, and build it frame by frame in HyperFrames. Faceless means every visual is invented downstream — there is no capture step and no real asset inventory.

The front door is /hyperframes. You are the orchestrator. Run each step, verify its gate, and only then continue. This skill is for explaining a topic from text, with no product and no website to capture. Any other intent, a bare "make a video", or any uncertainty → read /hyperframes first — the intent layer owns every route decision, and a fresh creation arriving here without BRIEF.md goes through it anyway (Setup's opening rule).

You are the orchestrator. Work in videos/<project>/. Run steps in order and pass each gate before continuing. User-gated steps are Step 0, Step 3, and Step 6. Read ../hyperframes/references/brief-contract.md before Step 0 — it defines the gate types and how BRIEF.md's flow/storyboard derive the mode that governs the Step 3/4/6 gates. Do every step yourself except Step 5, where you dispatch one sub-agent per frame. Do not put design or motion rules here; those live in the frame-worker sub-agent, this skill's local ../hyperframes-animation/rules/ + ../hyperframes-animation/blueprints/, and hyperframes-creative.

Workflow: Step 0 setup → hyperframes.json; Step 1 brief → capture/extracted/; Step 2 design system → frame.md; Step 3 storyboard/script → STORYBOARD.md and SCRIPT.md; Step 3.1 audio → audio_meta.json; Step 4 visual design → enriched STORYBOARD.md; Step 5 frames → compositions/frames/NN-*.html and index.html; Step 6 final render → renders/video.mp4.
