# Review and ship

Read an agent's changes, get a second review, commit, open a pull request, and let Machine Code watch it until it's green.

Canonical page: https://themachine.myapps.ai/docs/code/review-and-ship

## Read the changes

Open **Changes** (**Ctrl+Shift+G**) to see everything the agent changed, file
by file. Click a file to see its diff, or open it in the [code
editor](/docs/code/code-editor) to make your own edits.

The **Commits** section lists the commits on the task's branch. On your main
branch, or when nothing is ahead of the base branch, it shows the branch's
**Recent commits** instead. Click one to see its files and diffs.

## Review with Machine

For a second pair of eyes, click **Review with Machine** in the diff or in
the chat's **Changes** card. A Machine agent reads the diff and reports what
it finds. Ask the task's agent to fix anything you agree with.

## Commit

Click **Commit** in the toolbar, or **Commit…** above the diff. Write a
message, or leave it blank and Machine writes one. Click **Commit**.

## Open a pull request

Click **Create PR**.

1. Machine Code pushes the branch and opens **Create a pull request**.
2. Write the title and description yourself, or click **Write with Machine**
   to draft them from the changes.
3. Tick **Draft** if it isn't ready for review.
4. Click **Push and create pull request**.

Pull requests work with GitHub. If the GitHub command line (`gh`) isn't on
your computer, Machine Code uses the GitHub app you connected in Machine
instead.

After that, the toolbar shows **View PR**, and the pull request pane shows
its **Checks**.

## Watch a pull request

Turn on **Watch PR** in the pull request pane and Machine Code keeps an eye
on it for you. When a check fails, a reviewer comments, or the branch has
conflicts, it wakes the agent to deal with it. It gives up after a few
rounds, so a stuck PR doesn't spend credits forever.

To fix everything at once, click **Fix all … with agent**.

### Auto-merge when green

Turn on **Auto-merge when green** as well, and Machine Code merges the pull
request once its checks pass. You can also merge
yourself with **Merge**: squash, merge commit, or rebase.

Watching works for GitHub pull requests.
