Handoff

Handoff -- Session Context Transfer

When to use

• You are about to hit context limits and need to preserve task state
• A task needs to continue in a fresh session (yours or another agent's)
• Inter-agent delegation of a complex, multi-step task
• User explicitly says /handoff or asks to "save context for later"
• Before a /checkpoint when the task is too complex for 3-5 bullet points

Arguments

Examples:

• /handoff purpose="Continue the Pipedrive connector PR review and address CI failures"
• /handoff purpose="Finish the scheduler forceSend implementation" target=dev2
• /handoff purpose="Debug the auth redirect loop" output=/tmp/handoff-auth.md

Procedure

1. Gather context

Collect data from these sources (skip any that return empty):

# Active kanban cards (assigned to current agent or recently touched).
# Via the dashboard API, NOT the sqlite3 CLI: sqlite3 (and jq) are absent on a
# stock Linux install -- measured on two live hosts 2026-08-04, where the CLI
# call died with exit 127 while python3 was present on both.
AGENT_ID="$(echo $BOT_NAME | tr '[:upper:]' '[:lower:]')"
PORT="$(sed -n 's/^WEB_PORT=//p' .env 2>/dev/null | head -1 | tr -d '"')"; PORT="${PORT:-3420}"
curl -s -H "Authorization: Bearer $(cat store/.dashboard-token)" \
  "http://localhost:$PORT/api/kanban" | AGENT_ID="$AGENT_ID" python3 -c "
import json,os,sys
me=os.environ.get('AGENT_ID','')
rows=[c for c in json.load(sys.stdin)
      if not c.get('archived_at') and ((c.get('assignee') or '').lower()==me or c.get('status')=='in_progress')]
rank={'urgent':0,'high':1,'normal':2,'low':3}
rows.sort(key=lambda c:(rank.get(c.get('priority'),9), -(c.get('updated_at') or 0)))
for c in rows[:10]:
    print(c['id'], '|', c.get('status'), '|', c.get('priority'), '|', (c.get('assignee') or '-'), '|', c.get('title'))
"

# Hot memories from last 24h
curl -s -H "Authorization: Bearer $(cat store/.dashboard-token)" \
  "http://localhost:$PORT/api/memories?agent=$AGENT_ID&category=hot&limit=10"

# Recent warm memories (project context)
curl -s -H "Authorization: Bearer $(cat store/.dashboard-token)" \
  "http://localhost:$PORT/api/memories?agent=$AGENT_ID&category=warm&limit=5"

# Today's daily log
DATE=$(date +%Y-%m-%d)
curl -s -H "Authorization: Bearer $(cat store/.dashboard-token)" \
  "http://localhost:$PORT/api/daily-log?agent=$AGENT_ID&date=$DATE"

Also include from your current conversation context:

• The last significant user/peer messages and decisions
• Any error patterns or debugging findings
• File paths and line numbers you were working on
• Git branch, uncommitted changes, open PRs

2. Generate HANDOFF.md

Structure with exactly these 5 sections:

# Handoff: {purpose}

Generated: {ISO timestamp}
From: {agent name}
To: {target agent or "next session"}

## Goal
{What the overall task is trying to accomplish. 2-3 sentences max.}

## Current Progress
{What has been done so far. Bullet list with specifics:
- File paths changed
- PRs opened (with URLs)
- Kanban card IDs and their status
- Key decisions made}

## What Worked
{Approaches, tools, or patterns that succeeded:
- Specific commands or API calls that gave good results
- Architecture decisions that held up
- Workarounds that solved blockers}

## What Didn't Work
{Dead ends, failed approaches, gotchas:
- Commands or approaches that failed and WHY
- Assumptions that turned out wrong
- Edge cases discovered}

## Next Steps
{Concrete, actionable items for the receiving session:
1. First thing to do (most specific)
2. Second thing
3. ...
Keep each step concrete enough to execute without asking questions.}

3. Deliver

File mode (default): Write HANDOFF.md to the project root (or output path).

Inter-agent mode (target= specified): Send the full HANDOFF.md content as an inter-agent message:

curl -s -X POST http://localhost:$PORT/api/messages \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $(cat store/.dashboard-token)" \
  -d "{\"from\":\"$AGENT_ID\",\"to\":\"TARGET\",\"content\":\"[HANDOFF] purpose: ... \n\n$(cat HANDOFF.md)\"}"

4. Confirm

Report to the user/caller:

• Where the handoff was written (file path or inter-agent message ID)
• Summary: how many kanban cards, memories, and log entries were included
• The purpose line for quick reference

Pitfalls

• Do NOT include secrets, tokens, or .env values in the handoff
• Do NOT include full file contents -- use paths and line numbers
• Keep it under 3000 words -- the receiving session needs room to work
• If target= agent is not running (check tmux), warn and fall back to file mode
• The handoff is a snapshot -- it goes stale. Include the timestamp prominently

Relation to other persistence mechanisms

The handoff READS from these systems but does not REPLACE them. After a handoff, the receiving session should still check the live state of kanban/memory -- the handoff is a starting-context accelerator, not the source of truth.
