Session Handoff

Compress the critical context from the current conversation into a prompt so the user can paste it into a new session and the new AI can pick up the work immediately.

The Problem

Long sessions accumulate cache tokens that slow responses and drain quota. But starting a new session cold loses all conversation context. This skill solves: compress context, don't lose context.

Execution Steps

Phase 1: Retrospective Scan

Scan back through the entire conversation history in sequence. Early context is easily lost to attention decay or compression truncation — scan from the beginning forward, don't rely only on recent memory.

Tag each piece of information with a priority:

• P0 (must include): information that, if lost, would cause the new session to make errors, redo work, or violate user intent
• P1 (should include): improves efficiency and avoids detours, but not fatal if lost
