Checkpoint

Write a durable, high-fidelity breadcrumb so the next context window (after /compact, /clear, or /resume) picks up exactly where this one left off. This is the manual, high-quality save; the PreCompact hook (~/.claude/hooks/pre-compact.sh) is the automatic fallback that writes the same HANDOVER.md via Haiku when you don't run this. The SessionStart hook reads HANDOVER.md back on the next compact/resume.

When to run

• Nearing the context limit mid-task (don't wait for auto-compact to fire at ~80%).
• At a natural boundary before /compact or /clear.
• Before stepping away from a long session.
