handoff

handoff is a skill for Claude Code from reidemeister94/development-skills. It costs 29 tokens per session (545 once invoked), scanned A, original, MIT.

A handoff document that records enough of a coding session for another person or agent to continue in a new chat. It captures the request, discoveries, decisions, current state, and next action.

In plain words
What is it for?
Use it when transferring unfinished work, preserving exact decisions, documenting relevant files and errors, or giving the next chat a clear starting point.
Why use it?
It removes the need to reconstruct important context from a long conversation. The document is stored temporarily outside the project repository.

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 9d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Handoff

Create a standalone document that lets a person or agent continue the work in a new conversation. Follow the writing contract. Preserve the user’s request, useful discoveries, exact decisions, current state, relevant files, and the next action. Do not copy the conversation or raw logs.

Compute the path

Use the OS temp directory, never the repo:

${TMPDIR:-/tmp}/handoff-YYYY-MM-DD-HHMMSS-{slug}.md
  • {slug} = kebab-case topic, from $ARGUMENTS if passed, else inferred from the work.
  • Resolve ${TMPDIR:-/tmp} with Bash; macOS may not use /tmp.

Write

Write the absolute path. Keep the first three sections. Include the later sections only when they carry useful information.

# Handoff: {topic}

## What the user wants
[Explain the requested result and why it matters. Preserve exact wording only for decisions that the next conversation must not reinterpret.]

## Where things stand
[Explain what works, what is incomplete or broken, and the evidence. Give exact files, line numbers, and errors where they matter.]

## Next step
[`$ARGUMENTS` as a clear directive, or the next concrete action inferred from the current state.]

## Decisions that must survive
- [Decision and reason. Add a rejected alternative only when it helps prevent the same debate.]

## What the next agent needs to know
- [Constraint, project rule, hidden dependency, environment detail, or known trap.]

## Files and existing work
- `path/to/file.ext` — [what it contains and why it matters]
- Plan: `docs/plans/NNNN__...md` — [what it settles]
- Chronicle: `docs/chronicles/NNNN__...md` — [what it records]
- Other: [PRD, ADR, issue, pull request, commit, or URL]

## Questions still open
- [Question, why it matters, and who can answer it.]

## Useful skills
- `development-skills:<name>` — [when and why to use it]

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.
