A Claude Code plugin that lets you hand off an in-flight task from one AI tool to another — Claude Code → Codex, Codex → Cursor, Cursor → a fresh Claude session — without losing decisions, dead-ends, or "what to do next." Sessions are named, so multiple parallel threads of work can coexist in the same repo. Ships: /handoff [session] — write the current session's state into HANDOFF.<session>.md /resume [session] — read that file, reconcile with git status, and execute the next concrete step A PreCompact hook that blocks context compaction until a fresh handoff exists, so Claude Code never silently summarizes away your unsaved state
