A branded video-production skill for creating animated explainers, product demos, and archive-style origin films. It uses Remotion, a React-based tool for rendering videos from code.

Use it to make software demos, feature launches, SaaS promos, animated explainers, and films assembled from existing footage.

It gives video work a defined production process and reusable visual treatment for branded content.

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	$0.00314	$0.06320
Opus 5	$0.00157	$0.03160
Sonnet 5	$0.00063	$0.01264
Haiku 4.5	$0.00031	$0.00632

Security

Grade A, and why

promo 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 11d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (templates/glass/assemble.py, templates/glass/scripts/detect_sections.py, templates/glass/scripts/wait_valid.py, …), 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 — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Makes two kinds of premium branded video. Powered by Remotion (React-based video) + Claude Code + the remotion-best-practices skill.

🎬 PICK THE MODE FIRST (ask the user if it's not obvious)

MODE A — ANIMATED EXPLAINER / DEMO. Fully animated, no real long-form footage as the spine. Deck demos, feature launches, the content-flywheel video, SaaS promos, branded explainers. → built from templates/glass/ (premium liquid-glass) or templates/saas/. See the glass section below. Worked example: ~/Downloads/engine/2026-06-12_WorkflowDemo (the FlywheelFilm composition).
MODE B — ARCHIVE / ORIGIN-STORY FILM. The user hands you a long assembly cut (their own edit — real footage, chapters separated by black frames) and wants it turned into a branded film: chapter cards between sections, scene-matched music per chapter, flash transitions, and a growth-curve payoff. → era cards + assemble.py. See the MODE B section below. Worked example: ~/Downloads/engine/2026-06-14_BrandHistory (a "4.5 years in ~5 minutes" origin film).

Both modes share the same brand-tokenized glass kit (sting, GlassBG, era cards, growth curve, brand constants.ts), so they look like one family. Rebrand per brand in constants.ts + public/ logos — never hard-code a brand name into a component.

When to use this (vs other video skills)

✅ Use this: standalone promo videos, SaaS demos, course teasers, feature launch videos, animated explainers from a URL
❌ Don't use this: talking-head clips, face-tracked reframing, filler-word surgery, captioning existing video (use shortform / caption-clips instead)

Ready-made SaaS animation templates

Three production-ready Remotion components for the "SaaS animation style" (the $1-2k/video style dominating tech-brand Instagram/TikTok in 2026). Drop them into any Remotion project:

templates/saas/SaasTextPopup.tsx — 4s branded intro with pop-in text + logo reveal
templates/saas/SaasGlassReveal.tsx — 6s glass-UI feature cards with backdrop-blur
templates/saas/SaasDashboardTour.tsx — 8s 3D dashboard tour with animated cursor

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
