New Skill: Session Continuity

Problem it solves: Claude loses all context when sessions restart or context windows compact. Users have to re-explain their entire task, decisions made, and progress from scratch.

What it does:

• Checkpoints working state (decisions, progress, modified files, next steps) to .claude/session-state.md
• Resumes with full context on session restart via /session-continuity
• Auto-suggests checkpoints before risky operations (large refactors, deployments)

Real use case: Working on a multi-file database migration. After 15+ messages of analysis and partial implementation, checkpoint saves the exact state. Next session resumes from where you left off instead of re-analyzing the codebase.
