Handoff

Write a handoff document summarising the current conversation so a fresh agent can continue the work. Save it to the temporary directory of the user's OS — not the current workspace. Resolve the temp dir from $TMPDIR, falling back to /tmp (or %TEMP% on Windows), and tell the user the absolute path.

Include a "Suggested skills" section that names the tt: skills the next agent should invoke (e.g. /tt:diagnose to continue a debugging loop, /tt:tdd to keep building test-first, /tt:prd-to-issues to slice the remaining work).

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

Redact any sensitive information — API keys, passwords, or personally identifiable information.

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