Handoff

Generate a HANDOFF.md in the project root that gives a fresh agent everything it needs to continue the current task without re-reading the entire conversation.

Why this matters

Context windows are finite. When a session ends or gets too long, the next agent starts cold. A good handoff document is the difference between the next agent picking up in seconds versus spending 10 minutes re-discovering what you already know. Write it as if you're briefing a colleague who is smart but has zero context about this project or task.

When triggered

1. Read the full conversation history and any files you modified or read during the session.
2. Write HANDOFF.md to the project root. If the file already exists, overwrite it completely.
