Skill Builder · Free tool

Turn your files and videos into agent skills

Upload files, paste source text, or add a video URL you own or have permission to use. We extract the useful workflow, verify what we can, and email you a ready-to-use starter skill for Claude Code or Cursor.

Upload docs, code, transcripts, audio, or video files. Large videos may take longer to process.

It takes a few minutes. We'll email you a download link when your skill is built and verified. We package the generated skill, not your raw source files.

How it works

1

Read your materials

We work from the files, video, URL, or source text you provide, with a rights check before anything is submitted.

2

Extract the real procedure

A model separates the actual steps from the intro and filler — tools, prerequisites, gotchas, and snippets included.

3

Verify, then email

Every skill is tested before we send it. The package contains generated instructions and helper files, not a copy of your raw sources.

What you get back

---
name: setup-nextjs-project
description: Scaffold a new Next.js app with the App Router. Use
  when the user wants to start, bootstrap, or initialize a Next.js project.

# Set up a Next.js project

## Prerequisites
- Node.js 18+ installed
- npm available on PATH

## Procedure
1. Scaffold the app     npx create-next-app@latest my-app
2. Move into it         cd my-app
3. Start the dev server npm run dev   → http://localhost:3000

## Common gotchas
- If port 3000 is busy, Next.js prompts for another port.

Open the email link or the Skill Library and download the generated .skill file.

2

Give it to your AI

Paste the whole file into Claude, Cursor, Codex, LM Studio, or any AI chat that accepts long instructions.
