claude-remotion-kickstart: Command for Claude Code

.claude/commands/new-composition.md

new-composition is a command for Claude Code from jhartquist/claude-remotion-kickstart. It costs 9 tokens per session (747 once invoked), scanned A, original, MIT.

A command that creates the starter files and folders for a Remotion video composition. Remotion is a tool for building videos with React components.

In plain words
What is it for?
Use it to create a named composition with configuration, content, title and content segments, and the surrounding source folder structure. It converts the name into suitable folder and component formats.
Why use it?
It removes the repetitive setup needed before building a new composition and applies consistent naming and folder conventions.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: positional $N argument.

This is jhartquist/claude-remotion-kickstart's own configuration. It tells Claude Code how to work on claude-remotion-kickstart itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-remotion-kickstart configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { TitleSlide } from "../../../components/TitleSlide";.

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.

Security

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.

task

Create a new Remotion video composition named "$1".

steps

  1. 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")
  2. Create the folder structure:

    src/compositions/{folder-name}/
    ├── Composition.tsx
    ├── config.ts
    ├── content.ts
    └── segments/
        ├── TitleSegment.tsx
        └── ContentSegment.tsx
    
  3. 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.
