Write a handoff document so a fresh agent can continue this work without re-reading the full conversation.

Step 1 — Determine the target path

Check git branch (git rev-parse --abbrev-ref HEAD). Use no-git if not in a repo.
Generate a unique filename: YYYY-MM-DD-HHMM-<branch>.md using date +%Y-%m-%d-%H%M.
Target: docs/handoffs/<filename>. Create the directory if needed.
If prior handoffs exist, read the most recent (sort by filename) and carry forward still-relevant open questions.

Step 2 — Detect the handoff type

Signal	Type
git repo + edited source files + plan/todos	Code task
requirements/, context files, running skill workflow	Document/workflow
Neither	Lightweight
