That's it. Reads the Codex session (task, git log, last N turns, session file pointer), builds a structured handoff, launches Claude with it as the first message. Works all 6 directions between Claude Code, Codex CLI, and OpenCode.

Shorthand for power users: rses cc w cdx --last

~1200 lines, one npm dep (commander), zero config. Node 22+ built-in SQLite for the session indexes.

npm i -g rses-cli
