Make Claude Code compact itself: a CLAUDE.md rule plus a script that types /compact into its own tmux pane once the turn ends

A developer published a workaround that lets Claude Code trigger its own /compact command, since the tool cannot invoke it internally. A rule added to CLAUDE.md has Claude run a compact-self script as its final action, and the script waits for the turn to end before typing /compact plus the context to keep into Claude's own tmux pane and pressing Enter. The approach requires tmux, and the author notes it will not type into a pane that has been scrolled back and can collide with user input if typing begins just as a turn ends.

Claude Code can't run /compact on itself, so this does it from outside. A rule in CLAUDE.md has Claude run compact-self "<what to keep " as the last thing it does when it finishes a task. The script waits in the background until the turn is over, then types /compact <what to keep into Claude's own tmux pane and presses Enter. Needs tmux. 1. Save compact-self as ~/.claude/bin/compact-self and make it executable chmod +x . 2. Merge settings.json into ~/.claude/settings.json . The Stop hook records when a turn ends; the allow rule lets Claude run the script without asking. 3. Add the rule in rule-for-CLAUDE.md to ~/.claude/CLAUDE.md . It won't type into a pane you've scrolled back in. It doesn't check the input line, so if you start typing in that pane just as the turn ends, the two get mixed.
