Handoff Out

Create a local markdown handoff packet from current workspace facts, Miller context, impact analysis, and explicit session notes. This is a skill workflow, not a Miller MCP tool or CLI command.

Rules

• Store packets under .miller/handoffs/; write both a timestamped packet and .miller/handoffs/latest.md.
• Goldfish is not required and is not called automatically. Include only session context the active agent can state directly.
• Do not include secrets, credentials, tokens, private keys, customer data, or raw environment dumps in session notes or copied output.
• Keep the packet actionable: current state, changed files, impact, context, next action, and validation checklist.
• Do not commit .miller/handoffs/ packets.

Workflow

1. Confirm Miller freshness:

workspace(operation="status", format="json")
workspace(operation="health")

If health reports stale, missing, or corrupt sidecars, run workspace(operation="refresh") before collecting packet evidence. From JSON status, record index.built_revision and index.latest_revision as index_built_revision and index_latest_revision; do not invent a generic revision field.

2. Capture local git facts with shell/git:

git rev-parse --show-toplevel
git branch --show-current
git rev-parse --short HEAD
git status --short
git diff --stat
git diff --name-only

3. Capture Miller impact and context:

impact(git=true)
context(query="<goal, changed area, or next action>", token_budget=<budget>)

If the worktree is clean, write no local diff in the Impact section and use the goal/session notes to drive context(...).

4. Write the packet under .miller/handoffs/.

Filename shape:

.miller/handoffs/YYYY-MM-DDTHH-MM-SSZ-<source>-to-<target>-<branch>-<short-head>.md
.miller/handoffs/latest.md

Use UTC time. Sanitize harness and branch names for filenames.

## Resume Prompt

<Prompt the receiving agent can start with.>

## Current State

<Workspace status, branch, HEAD, dirty files, and concise state summary.>

## Changed Files

### git status --short

```text
<exact git status --short output, or "clean">

git diff --name-only

<exact git diff --name-only output, or "none">

git diff --stat

<exact git diff --stat output, or "none">

Impact

<Miller impact output for the working-tree diff, or explicit "no local diff".>

Context Bundle

Session Notes

<Agent-authored notes: what was tried, what failed, decisions made, constraints, and current intent. Do not include secrets.>

Next Action

Source Pointers

<Files, plans, tests, commands, or Miller calls worth opening first.>

Validation Checklist

• Same workspace root?
• Same branch?
• Same HEAD or acceptable drift?
• Dirty state and changed-file list match packet?
• Miller workspace fresh?
• Re-run impact if drifted?

## Final Check

Before reporting success:

```bash
test -s .miller/handoffs/latest.md
git check-ignore -q .miller

Report the timestamped packet path, whether the packet is safe for the target harness to read, and the next action. Do not paste the full packet unless the user asks.
