# Install ChatCut in Google Antigravity

Paste this into Google Antigravity on your computer:

> Read ChatCut.io/antigravity to install ChatCut

Antigravity adds the ChatCut plugin, installs ChatCut Desktop on your Mac or Windows PC, connects it, and then asks you to start a new conversation, where ChatCut's tools and Skills are ready. Sign in once, in the browser page or the ChatCut window. Your projects and media stay on your computer.

## For Antigravity: install ChatCut

If you are an Antigravity agent reading this guide for a user, carry out the installation now; do not only summarize the steps. Tell the user briefly what you are doing at each step.

Continue only inside Google Antigravity (App, CLI or IDE) on the user's own macOS 13+ or Windows 10+ x64 computer with a graphical desktop, a shell and the `agy` CLI. In another host, read [ChatCut.io/desktop](https://chatcut.io/desktop) instead. A Linux, headless or remote shell cannot install the app on the user's computer: explain that and stop.

```sh
agy --version
```

If `agy` is missing, ask the user to install the Antigravity CLI, or to add ChatCut from **Customizations → Marketplace** once it is listed. If `agy` reports "not currently available in your location", stop: Antigravity is not available for this account or region, and that restriction must not be bypassed.

### 1. Add the ChatCut plugin

```sh
agy plugin list --json
```

If `chatcut-desktop` is already enabled, skip to step 2. Otherwise install the Desktop package from its subdirectory, not the repository root:

```sh
agy plugin install https://github.com/ChatCut-Inc/agent-plugin/tree/main/antigravity-desktop
```

Run `agy plugin list --json` again and check that `chatcut-desktop` is enabled with 1 skill. A disabled plugin can be enabled in Antigravity's installed-plugin controls. Do not report success if this check fails; keep the exact error.

An older `chatcut` plugin (the hosted Web package) can stay installed next to it; leave it unless the user asks to remove it.

### 2. Install and connect ChatCut Desktop now

The plugin's Skill loads only in a new conversation, so follow it in this one. Read it in full:

```sh
curl -fsSL https://raw.githubusercontent.com/ChatCut-Inc/agent-plugin/main/antigravity-desktop/skills/connect-chatcut-desktop/SKILL.md
```

On Windows, use `curl.exe`. Carry out its steps 1–5 in one go: reuse a working `chatcut_desktop` connection, otherwise install Desktop with `CHATCUT_INSTALL_SOURCE=antigravity_marketplace`, register `chatcut_desktop` with `agy mcp add`, link Desktop's Skills into `~/.gemini/config/skills`, and finish with the hand-off message and copyable prompt for a new conversation. Do not add a ChatCut Web server.

## Troubleshooting

- **"not currently available in your location":** stop and explain; do not attempt a workaround.
- **Plugin installs with no skills, or as a `gemini-cli` extension:** the repository root was installed instead of the subdirectory. Uninstall that plugin and install the `/tree/main/antigravity-desktop` URL from step 1.
- **Desktop launcher missing after install:** ask the user to open ChatCut once, then check again. Never create or edit the launcher.
- **No `chatcut_desktop` tools in the new conversation:** check that **Customizations → Installed MCP Servers** lists `chatcut_desktop` as enabled, refresh it there once, and start another conversation.
