# Handoff: Close When a parked task is resolved, its handoff file is no longer needed. Closing a handoff means deleting `.handoffs/handoff-NNNN.md`. Because this permanently removes a file, always confirm before deleting. ## Step 1 — Resolve which handoff - If `.handoffs/` does not exist or is empty, tell the user there are no saved handoffs to close and stop. - If the user gave a number, target `.handoffs/handoff-NNNN.md` (zero-pad it). - If they referred to a topic instead, match it against the `title` and `<handoff-summary>` of the files; if ambiguous, ask which one. - If the specific file does not exist, say so and list the handoffs that do exist. ## Step 2 — Show what will be closed and confirm Read the file and show the user the number, title, and summary of the handoff about to be deleted, so they can confirm it is the right one. Ask for explicit confirmation before deleting — for example: > Handoff `0002` — "Migrate config to TypeScript". Closing this will delete > `.handoffs/handoff-0002.md` permanently. Go ahead? If the user already gave a clear, unambiguous instruction to delete a specific numbered handoff, you may treat that as confirmation and proceed — but still show what is being removed. ## Step 3 — Delete the file Remove the file: ```bash rm .handoffs/handoff-NNNN.md ``` (On Windows: `Remove-Item .handoffs\handoff-NNNN.md`) (In some environments deleting a file may prompt for permission — that is expected; let the user approve it.) ## Step 4
