# Introduction

> Chatfuel SDK scaffolds an app of your own on Chatfuel’s infrastructure, in one command, as source you keep.

The wizard runs once. After it, the CLI is gone and what you have is an ordinary React + Vite
project you own — no framework of ours between you and your code, and nothing in your
`package.json` pointing back at our repository. The design system, the API client and the proxy
are copied in as source instead. That is the whole trade: a component you disagree with is a
file you can edit, and upgrades are a re-run of the wizard or a diff you apply yourself, not
`npm update`.

What it writes is an app wired to your Chatfuel workspace — an operator inbox, a CRM, deals,
bookings, everything the AI agent knows, a flow builder. You choose which of those you want
before anything is written to disk. The wizard is MIT, and so is the app it leaves behind.

## Three ways in [#three-ways-in]

<Cards>
  <Card title="Run the command" href="/docs/quickstart" description="npx @chatfuel/wizard, four questions, and the app running on your machine." />

  <Card title="Add it to a project you already have" href="/docs/what-you-get" description="--embed copies the modules into src/chatfuel/ instead of writing a new app." />

  <Card title="Hand it to your coding agent" href="/docs/first-change" description="The wizard installs one skill per module, then the agent does the next change." />
</Cards>

That third one is the point of the run rather than a bonus. The wizard installs a skill per
module — `.claude/skills/chatfuel-<id>/` for Claude Code, `.agents/skills/chatfuel-<id>/` for
Codex CLI — and writes the instructions file each of them reads on startup, `CLAUDE.md` or
`AGENTS.md`. Each skill carries the operations of that module and the edges of the API behind
it, which is why "add a column to the deals table" is a sentence you can type rather than a file
you have to find. If you want to start from the agent instead of from the terminal, this site
serves the same entry point as a skill at `/SKILL.md`.

## What is in it [#what-is-in-it]

Thirteen modules. `core` is installed with all of them and has no interface of its own — it is
the transport, the error envelope, the pagination and the proxy spec. The other twelve are each
a directory under `src/modules/<id>/` in the app you end up with, and each adds a surface to it
— except sign-in, which adds no page of its own and instead decides who may reach the others.

for the tree it leaves on disk, and [deploy](/docs/deploy) for putting it in production.

<Callout type="info">
  A Chatfuel token can read and change every bot in an account, so it never reaches the browser.
  Calls go to a same-origin `/chatfuel/*` path and a proxy attaches the token server-side.
