handoff

name	handoff
description	Compact the current conversation into a handoff document for another agent to pick up.
argument-hint	What will the next session be used for?

Write a handoff document summarising the current conversation so a fresh agent can continue the work. Save it as an in-memory tmp file at $TMPDIR/claude-handoff/<short-slug>.md (create the directory if missing). On macOS $TMPDIR is a per-user tmpfs-style location — fast, ephemeral, survives until reboot.

Before writing, list $TMPDIR/claude-handoff/ and read any existing file with the same slug — extend it rather than overwriting. Print the absolute path of the saved file at the end so the next session can Read it directly.

How to create the file

1. Resolve the path with Bash, stripping any trailing slash from $TMPDIR (macOS leaves one, producing // otherwise):

   DIR="${TMPDIR%/}/claude-handoff" && mkdir -p "$DIR" && echo "$DIR/<slug>.md"
   

2. Check for an existing handoff with the same slug:

   ls "${TMPDIR%/}/claude-handoff/" 2>/dev/null
   

   If <slug>.md exists, write to the another file with a different name (e.g. <slug>-<label>.md).
3. Use the Write tool with the absolute path from step 1 (not the $TMPDIR literal — Write does not expand shell variables).
4. Print the final absolute path back to the user.

Required structure:

• Goal — what the next session should accomplish
• State — what's done, what's in progress (reference commits/PRs/files by path, don't restate diffs)
• Next steps — concrete first actions
• Open questions / risks
• Suggested skills — skills the next session should invoke

Do not duplicate content already captured in other artifacts (PRDs, plans, ADRs, issues, commits, diffs). Reference them by path or URL.

If the user passed arguments, treat them as a description of what the next session will focus on and tailor the doc accordingly.
