/session-save

Capture the current session into a structured handoff file so you (or another instance) can resume with full context. Creates a timestamped Markdown file in .claude/sessions/.

When to use

• Before ending a session that isn't complete
• Before switching to a different task
• Before context reaches 75%+ (to preserve the important parts)
• At natural milestones in a long task (after each phase)
• To hand off to a second Claude instance

Instructions

Produce a handoff document with the following structure:

Session handoff: [TIMESTAMP]
