Source documentation, not instructions for this website. Review permissions before running any commands.
A handoff is a baton, not a backpack: it carries just enough for the next session to resume, and points at everything else. The receiving agent has none of this conversation's context, so the document is the entire transfer — but it must stay compact, or it competes for the very context budget it is meant to preserve.
Core principle: Reference artifacts by path or URL; never duplicate their content into the handoff.
The optional [focus] argument shapes the summary toward the next objective (e.g. /groundwork:handoff finish the auth refactor). Without it, summarize toward the most recent active thread.
Gather what already exists rather than restating it. Run as needed:
git rev-parse --abbrev-ref HEAD # current branch
git log --oneline -5 # recent commits
git status --short # uncommitted changes
git diff --stat # scope of working-tree changes
Note paths to PRDs, plans (.groundwork-plans/), ADRs, specs, and any issue/PR URLs. These become links, not content.
Write to a temp path outside the repo, slug derived from the focus:
SLUG=$(echo "${ARGUMENTS:-session}" | tr '[:upper:] ' '[:lower:]-' | tr -cd 'a-z0-9-' | cut -c1-40)
OUT="${TMPDIR:-/tmp}/groundwork-handoff-${SLUG}.md"
The document has exactly these sections:
| Section | Contents |
|---|---|
| Summary | Focused recap of the conversation, tailored to the next objective. Decisions made and why; dead ends ruled out. |
| State | What is done, what is in progress, what is blocked. Branch and commit refs. |
| Next objective | The single thing the receiving session should accomplish next. |
| Artifacts | Bulleted links — paths, branch names, commit SHAs, diffs, issue/PR URLs. References only. |
| Suggested skills | Which Groundwork skills to invoke next, and a pointer to [[using-groundwork]] to map any remaining work. |

# Handoff
## Overview
A handoff is a **baton, not a backpack**: it carries just enough for the next session to resume, and points at everything else. The receiving agent has none of this conversation's context, so the document is the entire transfer — but it must stay compact, or it competes for the very context budget it is meant to preserve.
**Core principle:** Reference artifacts by path or URL; never duplicate their content into the handoff.
## When to Use
- Ending a session with work still in progress
- Handing a task to another agent or person
- Approaching context compaction and wanting a durable resume point
The optional `[focus]` argument shapes the summary toward the next objective (e.g. `/groundwork:handoff finish the auth refactor`). Without it, summarize toward the most recent active thread.
## Process
### 1. Locate work products
Gather what already exists rather than restating it. Run as needed:
```bash
git rev-parse --abbrev-ref HEAD # current branch
git log --oneline -5 # recent commits
git status --short # uncommitted changes
git diff --stat # scope of working-tree changes
```
Note paths to PRDs, plans (`.groundwork-plans/`), ADRs, specs, and any issue/PR URLs. These become links, not content.
### 2. Compose the document
Write to a temp path **outside the repo**, slug derived from the focus:
```bash
SLUG=$(echo "${ARGUMENTS:-session}" | tr '[:upper:] ' '[:lower:]-' | tr -cd 'a-z0-9-' | cut -c1-40)
OUT="${TMPDIR:-/tmp}/groundwork-handoff-${SLUG}.md"
```
The document has exactly these sections:
| Section | Contents |
|---------|----------|
| **Summary** | Focused recap of the conversation, tailored to the next objective. Decisions made and why; dead ends ruled out. |
| **State** | What is done, what is in progress, what is blocked. Branch and commit refs. |
| **Next objective** | The single thing the receiving session should accomplish next. |
| **Artifacts** | Bulleted links — paths, branch names, commit SHAs, diffs, issue/PR URLs. **References only.** |
| **Suggested skills** | Which Groundwork skills to invoke next, and a pointer to [[using-groundwork]] to map any remaining work. |
### 3. Redact before writing
Strip secrets, API keys, tokens, credentials, and PII from every section. Replace with `[REDACTED]`. Never echo a `.env` value or auth header into the file.
### 4. Report the path
Print the absolute temp path so the user can hand it off. Do not move it into the workspace.
## Rationalizations
| Excuse | Reality |
|--------|---------|
| "I'll paste the plan/diff inline so it's all in one place" | That's the backpack. The next agent can open the path; copying it bloats the handoff and rots when the source changes. |
| "Writing it next to the code is more convenient" | The repo is not scratch space. Temp dir only — a handoff is transient and must never be committed. |
| "The secret is needed to resume" | Reference where it lives (env var name, secret manager path), never the value. |
## Red Flags
- The document file lives anywhere under the repository or worktree
- A PRD, plan, ADR, or diff is pasted in full instead of linked
- An API key, token, password, or PII appears in the text
- No "Suggested skills" section / no [[using-groundwork]] pointer
## Verification
- [ ] Document exists at a `${TMPDIR:-/tmp}/...` path, not inside the repo or any worktree
- [ ] Summary is tailored to the next objective (and to `[focus]` when given)
- [ ] State, Next objective, Artifacts, and Suggested skills sections all present
- [ ] Artifacts are links/paths/URLs — no copied source, plan, or diff bodies
- [ ] Secrets, tokens, and PII redacted
- [ ] Suggested skills names concrete skills and points at [[using-groundwork]]
- [ ] Absolute path reported to the user
