# Review changes

> Check what an agent changed, follow your branch, isolate work in worktrees and review pull requests without leaving Vato.

Vato shows Git information next to each conversation. Git features need Git installed on your computer and a project that is a Git repository.

## Review what an agent changed

When an agent edits files during a turn, the conversation shows a card such as **3 files changed**, with the lines added and removed.

- Click **Review** to show the diff of every file at once. Click it again to hide them.
- Click the arrow at the end of a file row to see only that file's diff (**View diff**).
- Hover a file row to preview its diff.
- Click a file name to open the file in your system's default app.
- When the card lists many files, click **Show** followed by the number of hidden files to see them all.

Some cards also show **Undo**, which rewinds the conversation to before this turn. With **Claude** and **Codex**, your files go back too. With other providers, only the conversation goes back. See [Start your first conversation](../agents/first-conversation.md).

## Follow your branch

The **Environment** panel on the right of the conversation shows:

| Row | What it tells you |
| --- | --- |
| **Changes** | Lines added and removed in this conversation. |
| **Local workspace**, **Worktree** or **Vato Cloud** | Where the agent reads and edits files. |
| Branch name | The current branch, or **No repository** if the folder isn't a Git repository. |

When the remote branch has new commits, a row **Pull 2 incoming commit(s)** appears, with the actual number.

1. Click it to see the incoming commits.
2. Click **Pull all** to bring them into your project.

## Isolate a conversation in a worktree

A worktree gives a conversation its own branch and folder, so its changes don't mix with yours. Choose it before you send the first message:

1. In a new conversation, click the environment button in the message toolbar. It shows **Local workspace** by default.
2. Choose **New worktree**, then **Choose the base branch**. You can also pick one of the **Existing worktrees**.
3. Send your message. The agent works in that worktree.

Manage worktrees in **Settings → Worktrees**:

- **Setup script** runs inside every worktree after it is created or reused, for example to install dependencies. Click **Save** after editing it.
- **Git checkouts** lists each worktree, its branch and its linked conversations.
- **Remove worktree** deletes the folder and its uncommitted changes. Move linked conversations back to the local workspace first.

## Pull requests, issues and Actions

Vato reads GitHub through the GitHub CLI. Install `gh` and sign in with `gh auth login` first.

1. In the main navigation bar, click **Conversation** to switch to **GitHub**.
2. Choose a tab: **Pull requests**, **Issues** or **Actions**.

In **Pull requests**, Vato lists the open pull requests of your project repositories. Use **Search pull requests** or filter by repository, then open one to see its details.

From a pull request you can, among other actions:

- **Approve**, **Request changes** or **Comment**.
- **Rebase and merge** when GitHub allows it.
- **Ask questions** to start a conversation where an agent reads the pull request and its diff.
- **Open on GitHub**.

Use **Create PR** to open a new pull request from a branch.

If a repository can't be read, Vato says so at the top of the list. Check your GitHub access, then refresh.
