Open Cross Session

Open Cross-session

Claude Code, Codex, Pi, OpenCode, and terminal agents message and wake each other — on one machine, and across the computers on your LAN (macOS, Linux, Windows). No server, no account.

ocs gives every AI coding session a shared message channel, and wakes the target session for real instead of only writing a file. Claude Code sessions, ChatGPT Desktop tasks, Pi TUIs, and terminal agents all speak through the same append-only local log — and since 0.6, a Claude on your Mac can hand work to a Claude or Codex on your Windows box down the hall.

For repeatable planning, implementation, and review across independent sessions, pair OCS with Session Flow.

OpenCode

OpenCode 2.2.1 or later uses a local plugin installed alongside the skill:

The plugin registers sessions that it actually observes, injects the current session identity into tool shells, and submits incoming messages to OpenCode's durable native queue (delivery: "queue"). Busy sessions finish their active turn first. DM, @mentions, replies, inbox/read, rename, no-wake, batch, doctor repair and paired LAN addressing use the same commands as other hosts. Queue acceptance does not prove a read or task completion. V1 is not supported; upgrade OpenCode first.

The installer adds plugins/ocs.js and skills/ocs/SKILL.md under the OpenCode configuration directory without editing your configuration. See the adapter contract for paths, lifecycle and verification.

New in 0.6: agents across your computers

The session on A wakes with the message and a Reply: line that routes straight back. Verified Mac ↔ Windows
