name: handoff
description: Prepare a verified resumption brief when moving work to another agent, device, or session, including local-to-cloud coding handoffs, and start the receiving agent with `runpane handoff`. Use for "hand this off," "continue on my Mac," "give this to Codex," or "save where we are."

# Handoff

You are the outgoing collaborator. Give the next person or agent the verified context, decisions, and lessons needed to pick up where you left off.

## Capture what matters

- Preserve the goal, why it matters, constraints, non-goals, and decisions with their reasons. Distinguish approved work from suggestions.
- Verify the current state. Record completed work, remaining work, meaningful failed attempts, blockers, and the next concrete action.
- Link authoritative instructions, plans, evidence, and artifacts. Make the brief self-contained and focused on what the next worker needs.
- Include pending approvals and the scope of authorized work. Treat launching the receiving agent as a separate, user-authorized action.

## Make coding work portable

- Identify the repository, branch, exact commit, issue/PR, and relevant setup instructions. Include project-specific checks with their results and the revision they tested.
- Inspect staged, unstaged, untracked, and unpushed work. Separate task changes from unrelated edits and verify which revisions and files are available remotely.
- Transfer task-specific code and files through an authorized push or access-controlled destination. Preserve unrelated work and identify any files still awaiting transfer.
- Record required tools, services, and credential setup references. Keep secret values in their approved secret store and check the receiving agent’s plugin, skill, and network prerequisites.
- Keep private code and patches in access-controlled locations. Identify the next step needed to resolve any transfer or permission blocker.

## Write the note

Write the brief as the handoff note in [references/note-template.md](references/note-template.md): a compaction of your session, in nine required `##` sections, for a reader with none of your context.

## Start the receiving agent

When the person asks for another agent to continue, on this machine or another of theirs, use `runpane handoff`. It works the same from any harness. "Hand this to Claude on my Mac" authorizes starting that agent; it does not authorize pushing.

1. Find the machine's name: `runpane workspace list` lists the person's machines (a unique prefix such as `macbook-pro` works). Ask when more than one fits.
2. Get the template outside the checkout, so it is never committed: `runpane handoff --template > ~/handoff.md`. Fill in every section; write "None" where one does not apply. Leave the front matter alone, and don't add instructions for the receiver: the CLI rewrites the front matter and appends them when it sends.
3. Make the work reachable. Commit the task's files yourself; leave unrelated edits uncommitted. If the branch is not pushed, ask before pushing, then push it or pass `--push` (it commits every remaining change except the note as WIP and pushes; it never forces).
4. Check the destination: `runpane handoff "claude opus on <machine>" --note-file ~/handoff.md --dry-run`. The destination is freeform: the agent (claude, codex, cursor), and optionally the model, the effort and the machine, such as `"codex gpt-5 high on parsa-devbox"` or `"cursor on this machine"`. `--machine`, `--agent`, `--model` and `--effort` override the text. Effort is supported for Claude and Codex; Cursor effort is rejected before committing or sending.
5. Send it: the same command without `--dry-run`. It finds the destination's saved repository with the same remote, writes the note to that machine's `~/.pane/handoffs/`, and starts the agent in a new Pane branched from yours. If it fails, relay its message; it names the fix (Pane not running there, repository not saved there, branch not pushed).
6. Tell the person which Pane started on which machine, and give them the `agents status` command it printed. The receiver pushes to your branch and reports back to your panel, so stop changing that branch.

The note is the handoff. Skip the two sections below unless the person also wants a saved page, a Grain workspace or a PR comment, or there is no receiving agent to start.

## Save one authoritative brief

- Honor an explicit destination. Otherwise, when Grain is connected, read its installed skill and update the existing task workspace; if none exists, create a clearly named one in `Development Artifacts`. Retain its ID for subsequent updates.
- When the handoff lands in a Grain workspace and the `session-trace` skill is installed, attach this session's trace to it.
- Make essential text directly readable to both humans and agents. Link existing artifacts and retain one authoritative brief.
- For cross-device delivery, prefer a public-safe Grain share when public sharing is authorized by the request or an established user preference. Otherwise use an appropriately restricted destination or ask before publishing.
- Inspect the full shared content for its intended audience. Use access-controlled GitHub when the brief requires private source or sensitive context. Return the verified share URL supplied by the service.
- If Grain is unavailable or unsuitable, save the handoff as a page in the work's page bundle (see [page](../page/SKILL.md)) and open it for the person. With a posting grant, also update a clearly labeled handoff/status section on the existing PR, or the issue if there is no PR. Preserve the original intent, acceptance criteria, and other contributors' content; use a timestamped comment when editing the body would be disruptive.
- If both destinations are unavailable, return a self-contained, copyable brief in chat with its save status. Create a new issue or PR when the user requests one.
- Keep necessary local working files and verify that required material also has a remotely accessible copy. Report connected save failures and the outcome of any fallback.

## Verify and deliver

- Read back the saved brief and check its links, revision, and sharing scope. Verify public links in a signed-out context when possible, and state the verification status of recipient access to private resources.
- Return the brief's link and a paste-ready instruction to resume, naming the first action and any transfer/access blockers.
- Tell the receiving agent to read repository instructions and reconcile this checkpoint with the current branch, issue/PR, and artifact state before acting.

WSL handoff is currently unsupported and is rejected before committing or sending anything. Use a native repository. Remote shells must be Bash, Zsh, Sh, Fish, or PowerShell; cmd is unsupported. A staged note must be unstaged before using `--push`.
