xsm enables cross-session messaging between Claude Code and Codex sessions running on the same machine or remote servers, allowing sessions to discover each other and exchange messages through project-scoped permissions. It operates entirely within the existing runtime infrastructure using Unix sockets and native delivery paths, with no external dependencies beyond the Python standard library.
