# flue add

Last updated Jul 17, 2026[View as Markdown](https://nightly.flueframework.com/docs/cli/add/index.md)

## Synopsis

```bash
flue add [<kind> <name|url>] [--print]
```

## Description

`flue add` fetches a blueprint — a Markdown implementation guide that an AI coding agent follows to build an integration into your project. It is not a package installer: the command prints the guide, and your coding agent applies it. Run with no arguments to list every available blueprint.

When invoked by a coding agent (detected from environment markers) or with `--print`, the guide’s Markdown is written to stdout. From a plain shell without `--print`, instructions for piping it to a coding agent are printed instead. Blueprints are fetched at run time from the registry at `https://flueframework.com/cli/blueprints/`.

[flue update](https://nightly.flueframework.com/docs/cli/update/) fetches the same guide for upgrading an existing integration.

## Arguments

| Argument    | Description                                                                                                                                                                                                                                                                 |
| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| <kind>      | The integration category: channel, database, sandbox, or tooling.                                                                                                                                                                                                           |
| <name\|url> | A blueprint name (slack, postgres, daytona, sentry, …; run flue add with no arguments for the catalog), or an absolute URL to provider documentation, which selects the kind’s generic build-from-scratch guide with the URL as the coding agent’s research starting point. |

## Options

| Option   | Description                                                                  |
| -------- | ---------------------------------------------------------------------------- |
| \--print | Write the blueprint Markdown to stdout regardless of coding-agent detection. |

## Examples

```bash
# List every available blueprint
flue add

# Add a Slack channel with Claude Code
flue add channel slack --print | claude

# Build a channel from scratch, starting the agent from a provider docs URL
flue add channel https://developers.notion.com/reference/webhooks --print | codex

# Add a Postgres persistence adapter
flue add database postgres --print | claude
```
