handoff

handoff is a skill for Claude Code, Codex from Szotasz/marveen. It costs 55 tokens per session (1,555 once invoked), scanned A, original, MIT.

A context-transfer document for continuing complex work in another session or with another agent. It records the current task, relevant project state, and what should happen next in a HANDOFF.md file or inter-agent message.

In plain words
What is it for?
Use it before a context limit, when switching sessions, when delegating work, or when you need to preserve detailed instructions for continuation.
Why use it?
It prevents important decisions and unfinished work from being lost when a session ends or the task changes hands.

    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
  • medium Excessive Agency · line 112
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

handoff scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

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

Argument Required Description
purpose YES What the next session should do with this context
target no Agent name (e.g. target=dev2) -- sends via inter-agent message instead of writing file
output no File path override (default: project root HANDOFF.md)

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'))

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

handoff is a skill published in the GitHub repository Szotasz/marveen (98 stars, last pushed yesterday), licensed MIT. It adds 55 tokens to every session and 1,555 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
