Automatic context rotation for Claude Code (no manual steps)

AI coding agents break when the context window fills up — they lose state, hallucinate, or auto-compact shreds the context you built up. I built a 3-hook pipeline that rotates before that happens, with a dry-run replay you can run locally (no LLM/API keys). Quick demo: - https://github.com/Vinix24/vnx-orchestration/tree/master/dem... How it works: ┌─────────────────┐ │ PreToolUse hook │── checks context % every tool call │ (≥65% → block) │ └────────┬────────┘ ▼ ┌─────────────────┐ │ Agent writes │── structured ROTATION-HANDOVER.md │ handover file │ (task state, files, progress, next steps) └────────┬────────┘ ▼ ┌─────────────────┐ │ PostToolUse │── detects handover → atomic lock │ launches rotator│ → vnx_rotate.sh (nohup, detached) └────────┬────────┘ ▼ ┌─────────────────┐ │ Rotator │── /clear via tmux → waits for SessionStart │ injects resume │ → pastes continuation prompt └─────────────────┘ Why 65%? It’s ~15 points before auto-compact (~80%), so there’s enough headroom to write a clean handover without racing compaction. I analyzed 5 projects attempting similar fixes — none have a full detect → handover → clear → resume → verify loop.
