Handover

Produce a compact, structured summary so a fresh agent or session can continue without re-deriving what already happened. This is a context-handover artifact, not a status report — the audience is the next agent, not a stakeholder. Save to the temporary directory of the user's OS, not the current workspace.

When to invoke

• 5-10% of the session limit remains with work unfinished: pause at the next safe point and write the handover — don't run to the last token and stop silently.
• Context usage passes 40% of the window on unfinished multi-step work.
• Context is about to cross an agent, session, or clear boundary — including when the user signals they're about to clear context — or work is blocked and non-obvious state must be preserved.
• User says "handoff", "handover", "wrap up session", or a near-equivalent.

Skip it when ample context remains and work is progressing, or when the work is complete and legible from the issue, PR, and tests.
