Session Summarize

Purpose

Compress long threads into a reusable handoff summary so new chats can continue with minimal context and lower token usage.

When to Use

Use this skill when:

• a thread is long (around 20+ messages),
• a task domain is switching (for example coding to deployment),
• user asks "summarize session", "start new thread", or "reduce context."

Workflow

1. Produce a concise session summary with:
   • objective,
   • decisions made,
   • files changed,
   • tests run and outcomes,
   • blockers,
   • exact next steps.
2. Ask user to start a new thread.
3. Instruct user to paste the summary as the first message in the new thread.
4. Continue work from that summary only, loading only task-relevant context.
