Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00035 | $0.01809 |
| Opus 5 | $0.00017 | $0.00905 |
| Sonnet 5 | $0.00007 | $0.00362 |
| Haiku 4.5 | $0.00003 | $0.00181 |
Grade A, and why
modern-short-video 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 9d ago.
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 — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Modern Short Video Skill
Create professional, modern product launch videos using Remotion and React.
Prerequisites (MANDATORY)
WARNING: Do NOT skip this step. Skipping will result in missing rich expression opportunities.
This skill extends Remotion best practices. You MUST do both:
-
Load the skill first:
/remotion-best-practices -
Read the SKILL.md of remotion-best-practices and identify which rules are relevant to the product (maps, charts, text animations, 3D, lottie, etc.)
Workflow
Step 1: Analyze Product & Select Rich Expressions (CRITICAL)
Before asking for screenshots, analyze the product and find relevant rich expressions from remotion-best-practices.
Replace static screenshots with dynamic content wherever possible:
- Map app → animated map with route drawing
- Dashboard → animated charts
- Text app → typewriter effects
- etc.
Read the relevant rule files from remotion-best-practices and use them.
Step 2: Device, Theme & BGM Questions
Use AskUserQuestion to ask:
-
Device Type: Is the product primarily for smartphone (SP) or PC/Desktop?
- SP (Smartphone) → Use phone mockup frame
- PC/Desktop → Use browser/desktop mockup frame
-
Screenshot Theme: Should screenshots be in Light mode or Dark mode?
- Dark mode (Recommended) → Blends with video background (#0a0a0a)
- Light mode → Higher contrast, screenshots stand out more
-
BGM (Background Music): Add background music?
- Yes (Recommended) → Download free music from Pixabay
- No → Create video without BGM
Step 3: Collect Screenshots
Note: Screenshots for scenes using rich expressions (Step 1) are not needed.
Required images (place in public/ folder):
| File | Purpose | Required |
|---|---|---|
mockup.png |
Main product screenshot (Mockups scene) | Yes |
feature-1.png |
Feature 1 screenshot | Yes |
feature-2.png |
Feature 2 screenshot | Optional |
feature-3.png |
Feature 3 screenshot | Optional |
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 9d ago First seen · 187 lines · 35 tokens per session scan A 3850b70caa91
modern-short-video is a skill published in the GitHub repository Marve10s/Better-Fullstack (738 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 1,809 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
