Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your machine
›Node.js 16+ with npm — verify with node --version
›Active project directory where you want to add add-sfx

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Steps

1. Add to remotion.media repo (must be done first)

In the remotion-dev/remotion.media repo:

Add the WAV file to the root of the repo

Add an entry to the soundEffects array in generate.ts:

{
  fileName: "my-sound.wav",
  attribution:
    "Description by Author -- https://source-url -- License: Creative Commons 0",
},

Run bun generate.ts to copy it to files/ and regenerate variants.json

Deploy

2. Add the export to packages/sfx/src/index.ts

Use camelCase for the variable name. Avoid JavaScript reserved words (e.g. use uiSwitch not switch).

export const mySound = 'https://remotion.media/my-sound.wav';

3. Create a doc page at packages/docs/docs/sfx/<name>.mdx

Follow the pattern of existing pages (e.g. whip.mdx). Include:

Frontmatter with image, title (camelCase export name), crumb: '@remotion/sfx'

<AvailableFrom> tag with the next release version

<PlayButton> import and usage

Description

Example code using @remotion/media's <Audio> component

Value section with the URL in a fenced code block

Duration section (fetch the file and use afinfo on macOS to get duration/format)

Attribution section with source link and license

See also section linking to related sound effects

4. Register in sidebar and table of contents

packages/docs/sidebars.ts — add 'sfx/<name>' to the @remotion/sfx category items

packages/docs/docs/sfx/table-of-contents.tsx — add a <TOCItem> with a <PlayButton size={32}>

5. Update the skills rule file

Add the new URL to the list in packages/skills/skills/remotion/rules/sfx.md.

6. Build

cd packages/sfx && bun run make
