# `ClaudeWrapper.DuplexSession.Adapter.Port`
[🔗](https://github.com/genagent/claude_wrapper_ex/blob/main/lib/claude_wrapper/duplex_session/adapter/port.ex#L1)

Default `ClaudeWrapper.DuplexSession.Adapter`: a real `claude`
subprocess over an Erlang port.

The port is opened by (and delivers its `{port, {:data, _}}` /
`{port, {:exit_status, _}}` / `{:EXIT, port, _}` messages directly to)
the session process, which calls `open/1` from its own `init/1`. The
returned handle is the port itself.
