### Teleport - Resume Sessions Across Machines

A powerful new `--teleport` feature allows you to resume Claude Code sessions from other machines or continue someone else's shared session.

**Usage:**

`# Resume by session ID claude --teleport abc123def456 # Resume from a URL claude --teleport https://claude.ai/chat/abc123def456` **Features:**

- Automatically fetches conversation history from remote sessions
- Switches to the appropriate git branch if needed
- Offers to stash uncommitted changes before switching branches
- Supports custom headers via `TELEPORT_HEADERS` environment variable
- Validates authentication status before proceeding

**Environment Variables:**

- `TELEPORT_RESUME_URL`: Override the default URL for session resumption
- `TELEPORT_HEADERS`: Pass custom headers as JSON (e.g., `export TELEPORT_HEADERS='{"Authorization": "Bearer token"}'`)

### Customizable Output Modes

Configure how Claude Code communicates with you by selecting from different output modes.

**Features:**

- Support for custom output modes stored in `.claude/output-modes/` directories
