Shell Channel

Communication channel for zylos shell — the CLI interactive mode.

How It Works

1. zylos shell starts a readline REPL and a Unix domain socket server
2. User input is sent to Claude via c4-receive (channel=shell, endpoint=socket path)
3. Claude responds via c4-send which invokes scripts/send.js
4. send.js connects to the Unix socket and delivers the response to the REPL
5. The REPL prints the response and prompts for the next input

Socket Protocol

• Socket path is passed as the endpoint (e.g., /tmp/zylos-shell-<pid>.sock)
• send.js connects, writes the full message as UTF-8, then closes the connection
• The REPL reassembles the message from socket data events
