## ADDED Requirements

### Requirement: Clone mode instance creation
The system SHALL support creating tool instances with a clone mode that clones the repository into the instance directory.

#### Scenario: Create instance in clone mode
- **GIVEN** an authenticated user with a repository that has an SSH key and remote URL
- **WHEN** they create an instance with `clone_mode: "clone"` and `branch: "main"`
- **THEN** the system clones the repository into the instance directory
- **AND** the compose file uses the clone path as `REPO_PATH`
- **AND** the instance record stores `clone_mode="clone"` and `branch="main"`

#### Scenario: Create instance in mount mode
- **GIVEN** an authenticated user with a repository
- **WHEN** they create an instance with `clone_mode: "mount"` (or omit the field)
- **THEN** the compose file uses the host repository path as `REPO_PATH`
- **AND** the instance record stores `clone_mode="mount"`

### Requirement: SSH key mounting for git operations
The system SHALL mount the repository's SSH key into clone-mode containers for git operations.

#### Scenario: Start clone-mode instance
- **GIVEN** a clone-mode instance with an associated SSH key
- **WHEN** the instance is started
- **THEN** the SSH key is decrypted and written to `instance_dir/.ssh/`
- **AND** the `.ssh` directory is mounted into the container
- **AND** the container can perform git push/pull operations

### Requirement: Dirty check on clone deletion
The system SHALL check for uncommitted changes before deleting a clone-mode instance.

#### Scenario: Delete clean clone
- **GIVEN** a clone-mode instance with no uncommitted changes
- **WHEN** the user requests deletion
- **THEN** the instance is deleted successfully

#### Scenario: Delete dirty clone with confirmation
- **GIVEN** a clone-mode instance with uncommitted changes
- **WHEN** the user requests deletion
- **THEN** the system returns a warning with change details
- **AND** the user must confirm deletion

#### Scenario: Force delete dirty clone
- **GIVEN** a clone-mode instance with uncommitted changes
- **WHEN** the user requests deletion with `force=true`
- **THEN** the instance is deleted regardless of uncommitted changes
