Projects in Amp can now include more than one repository.
Additional repositories are checked out to an adjacent directory in the orb and the agent is made aware of them. The changes panel will show the diff across all repositories in the project.

To add additional repositories, specify them when creating the project or later in project settings. You can add up to 20 additional repositories per project.

Only the primary repository's .agents/setup script runs automatically on orb setup. If an additional repository requires initialization, you should update the primary's setup script to include this, or ask an Amp agent to make this update for you.
