Hook by koenvdheide
When your Claude Code session's real token count crosses a configurable threshold (default 450K), an informational reminder names the warm handoff file. A Stop hook continuously maintains an on-disk handoff JSON (cumulative file paths, in-progress todos, active subagent launches, recent user-message quotes). The /prep-compact skill reads this warm handoff and adds an analytical layer (decisions, constraints, blockers, verb-anchored next-step) to emit a tailored /compact <instructions> block.
