Worker Handover

Overview

When workers approach their turn limit (100 turns), they must create a handover that enables a replacement worker to continue without losing context.

Core principle: A replacement worker should understand the work as well as the original worker did.

Announce at start: "I'm approaching my turn limit. Creating handover for replacement worker."

State Management

CRITICAL: Handover context is stored in GitHub issue comments. NO local handover files.

State	Location	Purpose
Handover context	Issue comment	Full context for replacement worker
Git changes	Branch commits	Work completed so far
Test status	Issue comment	Current test state

Handover survives crashes because it's in GitHub, not local files.

When to Handover

Turns Used	Action
85+	Evaluate if handover needed
90+	Begin handover preparation
95+	Complete handover, prepare to exit
100	Exit (automatic)

Handover Format

Post to the issue with structured markers:

<!-- HANDOVER:START -->

Handover created by [WORKER_ID] at [TIMESTAMP]

## Creating a Handover

### Step 1: Assess State

```bash
# Check git status
git status
git log --oneline -10

# Check test status
pnpm test 2>&1 | tail -20

# Count modified files
git diff --name-only HEAD~[N]

Step 2: Post Handover to Issue

ISSUE=123
WORKER_ID="worker-1234567890-123"
BRANCH=$(git branch --show-current)
LAST_COMMIT=$(git log -1 --format='%h - %s')
COMMITS_AHEAD=$(git rev-list --count main..HEAD)

gh issue comment "$ISSUE" --body "<!-- HANDOVER:START -->

# Handover: Issue #$ISSUE

## Metadata

| Field | Value |
|-------|-------|
| Issue | #$ISSUE |
| Previous Worker | $WORKER_ID |
| Turns Used | 94/100 |
| Timestamp | $(date -u +%Y-%m-%dT%H:%M:%SZ) |
| Orchestration | $ORCHESTRATION_ID |

## Current State

### Branch Status
- **Branch:** \`$BRANCH\`
- **Commits:** $COMMITS_AHEAD commits ahead of main
- **Last Commit:** \`$LAST_COMMIT\`

[... rest of handover content ...]

<!-- HANDOVER:END -->"

Step 3: Commit Any Uncommitted Work

git add -A
git commit -m "chore: Save progress before handover

Worker $WORKER_ID reached turn limit.
Handover posted to issue #$ISSUE.

Orchestrator: $ORCHESTRATION_ID"

Step 4: Exit Gracefully

Worker exits after posting handover. Orchestrator will spawn replacement.

Receiving a Handover

When a replacement worker starts, it reads handover from issue comments:

Step 1: Read Handover from GitHub

ISSUE=123

# Get latest handover from issue comments
HANDOVER=$(gh api "/repos/$OWNER/$REPO/issues/$ISSUE/comments" \
  --jq '[.[] | select(.body | contains("<!-- HANDOVER:START -->"))] | last | .body')

echo "$HANDOVER"

Step 2: Verify State

# Verify branch
git branch --show-current

# Check current state matches handover
git status
git log --oneline -5

# Run tests
pnpm test

Step 3: Acknowledge Receipt

Post acknowledgment to issue:

**Handover Received**

**Replacement Worker:** [NEW_WORKER_ID]
**Continuing from:** [PREVIOUS_WORKER_ID]
**Attempt:** [N]

**Handover verified:**
- [x] Branch state matches
- [x] Tests status matches
- [x] Context understood

**Continuing with:**
[First task from "Recommended Next Steps"]

---
*Orchestration: [ORCHESTRATION_ID]*

Step 4: Continue Work

Follow the "Recommended Next Steps" from the handover.

Handover Quality Checklist

Before creating handover:

• All local changes committed
• Handover captures current state accurately
• Key decisions are documented
• Gotchas are noted
• Next steps are specific and actionable
• Files to review are listed in priority order
• Commands to run are tested and correct
• Handover posted to issue comment
• Work committed to branch

Bad Handover Examples

Too Vague

## Work Completed
- Did some stuff
- Made progress

## Next Steps
- Finish the feature

Missing Context

## Work Completed
- [x] Implemented the thing

## Next Steps
- Fix the tests

(No explanation of WHY tests are failing)

Good Handover Example

See the full format above for a complete, high-quality handover that includes:

• Specific commit references
• Test failure details
• Decisions with rationale
• Gotchas discovered
• Actionable next steps
• File priority list
• Verified commands

Integration

This skill is used by:

• worker-protocol - Triggers handover creation
• worker-dispatch - Provides handover to replacement workers

This skill uses:

• GitHub issue comments for handover storage
• Git for state verification
