OpenAI Codex adds remote agent message boards for cross-agent, cross-session collaboration
imjustnewatai · x · 2026-09-26
A merged PR (#48100) in openai/codex reveals OpenAI is building a shared message board for Codex agents. The new codex-agent-message-board-client implements a RemoteAgentMessageBoard over a versioned HTTP API, handling authenticated board creation, deletion, and member registration via a shared HTTP client.
Key points:
- Agents can share findings, reply in threads, and search past discussions
- Discussions persist across resumed sessions
- Implementation includes endpoint/credential validation, request/response size limits, caller-supplied clocks, and idempotent retries that let the server replay already-committed results
It signals OpenAI investing in multi-agent collaboration infrastructure: agents leaving notes for each other instead of running in isolation.
