Atuin launches Threads to sync and resume AI agent sessions across machines

Atuin, the maker of the shell history tool, released Atuin Threads in Atuin 18.24. Threads gathers AI coding agent sessions into one searchable history that syncs between machines, and lets a user resume a session started in one agent inside a different one — for instance beginning in Claude Code on a dev server and finishing in Codex on a laptop with context intact. At launch it supports Claude Code, Codex, Pi, Omp and OpenCode, with more planned. Capturing sessions is opt-in, synced data is end-to-end encrypted, and users can pick Atuin's hosted sync server, run their own, or stay local. An MCP server, installed with `atuin mcp install`, lets agents search earlier sessions themselves. Opt-in sharing for teams is still in development.
