# Summarize

Create a short handoff from information already visible in the active session, written so a fresh agent session can resume the work without other context.

The bar is the **cold-start test**: a fresh agent that has only this summary — no transcript, no memory of the session — must be able to pick the work back up and take the next action without guessing. Write to that reader, and check each section against the cold-start test before you finish: if a cold-start agent would still have to ask "what was the goal?" or "what was already verified?", the summary is not done.
