FuseBase agent plugins

The fusebase-apps plugin lets you create FuseBase apps by asking your coding agent, without opening a terminal. It works with Claude Code and Codex.

Install

Three ways to install. The first two need your agent's CLI on your PATH. The third does not, so it works everywhere.

Ask your agent

Paste this into Claude Code or Codex:

Install the fusebase-dev/agent-plugins marketplace and the fusebase-apps plugin from it.

The agent runs its own CLI to do this. That only works if the CLI is on your PATH, which it often is not when you installed the desktop app alone. If the agent reports that its command was not found, skip to installing from the app itself.

Run the commands yourself

These are the same commands the agent would run, so if asking the agent failed because the CLI was not found, these will fail the same way. Use the next method instead.

For Claude Code:

claude plugin marketplace add fusebase-dev/agent-plugins
claude plugin install fusebase-apps@fusebase

For Codex:

codex plugin marketplace add fusebase-dev/agent-plugins
codex plugin add fusebase-apps@fusebase

Install from the app itself

Both Claude Code and Codex can add the marketplace from their own interface. This needs no CLI, so it works when the other two methods do not.

Claude Code desktop

1. Click + next to the prompt box and pick Add plugins....
2. In the Plugins directory, click + (Add marketplace) at the top right.
3. Choose Add from a repository, enter fusebase-dev/agent-plugins, and press Sync.
4. Open the Code tab, select the fusebase marketplace, and install Fusebase apps.

Codex

1. Open Settings -> Plugins.
2. Click Add -> Add a marketplace.
3. Enter fusebase-dev/agent-plugins as the source and press Add marketplace.
4. Find FuseBase Apps under the Personal tab and press Install.

Claude Code needs /reload-plugins or a restart before a plugin installed mid-session becomes active.

What the plugin contributes

Three skills, and nothing else. No hooks, no agents, no MCP server, and nothing written to your CLAUDE.md or AGENTS.md.

Skill	What it does
create-app	Creates a FuseBase app. Picks your organisation, makes a directory, runs fusebase init, then hands off to the generated project's own skills.
existing-fusebase-app	Updates the CLI and the project's own agent instructions when you open an app that already exists.
install-cli	Installs, updates and authenticates the FuseBase CLI. Loads only when the CLI is missing or out of date.

Installing the plugin installs nothing else. The CLI and the login happen the first time you actually ask for an app.

What it does to your machine

The first time install-cli runs:

• macOS and Linux: installs the fusebase binary to ~/.local/bin, adding that directory to your PATH via your shell rc file if it is not there already. No sudo. Node is required, and the skill will help you install it if it is missing.
• An older install at /usr/local/bin/fusebase is removed first, because it would shadow the new one. That path needs root, so the installer stops and prints a single sudo rm line for you to run yourself.
• Windows: downloads and starts the signed FuseBase CLI installer. Windows shows the usual elevation prompt and you click Yes. The installer handles Node itself. Restart your agent afterwards so fusebase resolves.
• Authentication: fusebase auth opens your browser so you can log in to FuseBase.

Linux arm64 is not supported.

Updates

Skills change as they are tuned, so keep the marketplace syncing. Codex does this by default. Claude Code exposes a Sync automatically toggle when you add a marketplace, and install-cli asks you to confirm it is on.

Security

This plugin runs code on your machine with your privileges, as every plugin does. Everything it runs is in this repository in readable form, with no build step, so you can check it before installing. The installer scripts it invokes are published at thefusebase.com/fusebase-cli/.
