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 | $0.00009 | $0.00747 |
| Opus 5 | $0.00005 | $0.00374 |
| Sonnet 5 | $0.00002 | $0.00149 |
| Haiku 4.5 | $0.00001 | $0.00075 |
Grade A, and why
new-composition 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
task
Create a new Remotion video composition named "$1".
steps
-
Validate the name:
- Convert to lowercase for folder name (e.g., "My Video" → "my-video")
- Use PascalCase for component names (e.g., "my-video" → "MyVideo")
-
Create the folder structure:
src/compositions/{folder-name}/ ├── Composition.tsx ├── config.ts ├── content.ts └── segments/ ├── TitleSegment.tsx └── ContentSegment.tsx -
Generate files using these templates:
config.ts
// Segment durations in seconds
export const TITLE_DURATION_SECONDS = 3;
export const CONTENT_DURATION_SECONDS = 5;
content.ts
export const CONTENT = {
title: "{Composition Name}",
contentHeader: "Your Header",
contentBody: "Your content goes here.",
};
segments/TitleSegment.tsx
import { TitleSlide } from "../../../components/TitleSlide";
import { CONTENT } from "../content";
export const TitleSegment: React.FC = () => {
return <TitleSlide title={CONTENT.title} />;
};
segments/ContentSegment.tsx
import { ContentSlide } from "../../../components/ContentSlide";
import { CONTENT } from "../content";
export const ContentSegment: React.FC = () => {
return (
<ContentSlide header={CONTENT.contentHeader} content={CONTENT.contentBody} />
);
};
Composition.tsx
import { Series, useVideoConfig } from "remotion";
import { TitleSegment } from "./segments/TitleSegment";
import { ContentSegment } from "./segments/ContentSegment";
import { getDurationInFrames } from "../../config";
import { TITLE_DURATION_SECONDS, CONTENT_DURATION_SECONDS } from "./config";
import { createComposition } from "../../utils/createComposition";
const {ComponentName}Composition: React.FC = () => {
const { fps } = useVideoConfig();
const titleDuration = getDurationInFrames(TITLE_DURATION_SECONDS, fps);
const contentDuration = getDurationInFrames(CONTENT_DURATION_SECONDS, fps);
return (
<Series>
<Series.Sequence durationInFrames={titleDuration}>
<TitleSegment />
</Series.Sequence>
<Series.Sequence durationInFrames={contentDuration}>
<ContentSegment />
</Series.Sequence>
</Series>
);
};
const TOTAL_DURATION_SECONDS = TITLE_DURATION_SECONDS + CONTENT_DURATION_SECONDS;
export const {ComponentName} = createComposition({
name: "{ComponentName}",
component: {ComponentName}Composition,
durationInSeconds: TOTAL_DURATION_SECONDS,
preset: "Landscape-1080p",
});
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.

new-composition is a command published in the GitHub repository jhartquist/claude-remotion-kickstart (116 stars, last pushed 9mo ago), licensed MIT. It adds 9 tokens to every session and 747 once invoked, about $0.0000 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.
