Show HN: 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.
