Oi — Inter-Session Messaging

Send and receive messages between independent Claude Code sessions using filesystem mailboxes.

Commands

Parse the user's input to determine which subcommand to run. The scripts are located at ${CLAUDE_PLUGIN_ROOT}/skills/oi/scripts/.

register

Register this session with a name. Run:

bash "${CLAUDE_PLUGIN_ROOT}/skills/oi/scripts/register.sh" "<name>"

After registering, remember your session name for all future send and check calls. You MUST register before sending or checking messages.

send

Send a message to another session. You must be registered first. Run:

bash "${CLAUDE_PLUGIN_ROOT}/skills/oi/scripts/send.sh" "<your-name>" "<target>" "<message>"

check

Check your inbox for new messages. Run:

bash "${CLAUDE_PLUGIN_ROOT}/skills/oi/scripts/check.sh" "<your-name>"

Messages are cleared after reading. Report each message to the user with the sender and timestamp.

who

List all registered sessions and their status. Run:

bash "${CLAUDE_PLUGIN_ROOT}/skills/oi/scripts/who.sh"

Behavior

• If the user says /oi with no arguments, show a brief usage summary.
• If the user hasn't registered yet and tries to send or check, remind them to register first.
• Keep your registered session name in memory for the duration of the conversation.
