handoff

handoff is a skill for Claude Code from lttr/claude-marketplace. It costs 20 tokens per session (770 once invoked), scanned A, original, MIT.

A skill that writes a handoff note for the next Claude Code session. The note records the original request, completed work, recent conclusions, and next steps.

In plain words
What is it for?
Use it at the end of a coding session when another session needs to continue the work. An optional focus can determine which part of the work the note emphasises.
Why use it?
It prevents important context from being lost when work moves to a new session. Existing handoff notes are replaced with a fresh summary.

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 0 findings 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 11d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Write ~/.claude/custom-handoff.md (resolve ~ to the user's home directory) summarizing current work so the next Claude session can pick up where this one left off.

Focus argument

$ARGUMENTS, when present, is the user's steer for what the handoff should emphasize. Let it bias every section — GOAL, RECENT CONCLUSIONS, and NEXT especially — toward that thread of the work. Trim or drop details unrelated to the focus, and let NEXT lead with the focused action. Still keep # ORIGINAL PROMPT verbatim; the focus reshapes emphasis, not the recorded intent. When $ARGUMENTS is empty, weight sections as the rules below describe.

Steps

  1. Run trash-put ~/.claude/custom-handoff.md 2>/dev/null || true to remove any prior handoff (ignore error if file absent).
  2. Write fresh content per template. No merge, no preserve.

Template

# ORIGINAL PROMPT

<the user's opening prompt from this conversation, verbatim if short; otherwise a one-to-two-sentence summary that preserves the ask>

# GOAL

<one line: what we're doing now>

# DONE

- <thing done>
- <thing done>

# RECENT CONCLUSIONS

- <decision, agreement, or insight from last few turns — what shifted the plan>
- <open question raised at end, still unanswered>

# NEXT

<concrete next action — derived from RECENT CONCLUSIONS, not stale earlier intent>

# WATCH OUT

<gotchas; omit section if none>

# SUGGESTED SKILLS

- `/plugin:skill` — <why the next session should invoke it>

Rules

  • Terse, scannable, under 250 words total.
  • # ORIGINAL PROMPT anchors intent across sessions — do not drop it even if the work has drifted.
  • Weight the final turns heaviest. Conclusions, decisions, course corrections, and open questions from the last few messages drive NEXT. Early-conversation context is backdrop, not the lead.
  • # RECENT CONCLUSIONS captures what was just decided or learned — not a re-summary of DONE. If the last turns only restated earlier work, leave it empty rather than padding.
  • If user and assistant disagreed or pivoted near the end, record the resolution (or that it's unresolved).
  • Use file paths, not descriptions (e.g. src/auth.ts:42, not "the auth file").
  • No prose narration ("we decided to...").
  • Redact secrets. API keys, tokens, passwords, connection strings, and personal data never land in the file. Name where a value lives (.env:DATABASE_URL) instead of the value itself.
  • Point, don't copy. Anything already captured in a spec, ticket, ADR, commit, or diff gets referenced by path or id — never re-summarized here.
  • # SUGGESTED SKILLS names the skills the next session should invoke for this work, with a few words on why each. Omit the section when nothing specific applies.
  • Omit # WATCH OUT when there are no gotchas.

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.
