I run a lot of long unattended Claude Code sessions. When I measured them, half of my tokens came from turns where the context was already past 200k. That’s expensive, since every step resends the whole context, and quality degrades because of context rot. By hand the fix is the usual routine: ask for a handoff, /clear, feed it back. Enabling autocompact at 200k keeps the context short but leaves little control over what is handed over. I already tried to have Claude Code write handoff documents pre autocompact window with hooks, but with modding the solution gets a LOT better. Handoff-compact answers the autocompact trigger instead of the built-in summarizer. A fork of the session (whole context) writes a handoff-document (goal, state and what proves it, next step, decisions and why, ruled-out approaches, open questions, files and commits, the verify command, the last 10 prompts verbatim), and the conversation is replaced by it. Handoff + /clear, but in the same session, mid-turn, with nobody at the keyboard. Obviously vibe-coded. Take the idea or the mod itself and customize it with your own setup. Modding is awesome. Install: /plugin marketplace add trytofly94/handoff-compact /plugin install handoff-compact@handoff-compact Repo: https://github.com/trytofly94/handoff-compact (MIT). Needs Claude Code 2.1.287+ with mods enabled. “/compact classic” gives you the built-in summary once. submitted by /u/speciallight
