handoff

handoff is a skill for Codex from flonat/flonat-research. It costs 51 tokens per session (737 once invoked), scanned A, original, MIT.

A shared project handoff record for passing work between AI sessions, computers, or assistants. It stores the current project state, ownership, outcome, and restart information in a standard file.

In plain words
What is it for?
Use it to prepare, accept, or update handoffs when continuing a project in a new session or transferring responsibility between assistants.
Why use it?
It prevents the next session from having to reconstruct what happened or guess what remains. This reduces duplicated work and lost context when work changes hands.

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 5d 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Handoff

Use one client-neutral handshake for every route. Before acting, read ../shared/cross-client-handoff.md completely and follow its schema and state machine.

Choose the route

  • If the user names Claude or Codex, use that client as to.
  • If the user asks for the next or a fresh session without naming a client, set to to the current client. This is the default for Claude-to-Claude and Codex-to-Codex continuation.
  • Use to: either only when the task is deliberately client-agnostic.
  • Set from to the current client, or human when invoked outside a client session.

All routes write <project-root>/.context/ai-handoff.md. Do not create a separate client-specific handoff file.

Prepare a handoff

  1. Resolve the project root from the current working directory or the named project.
  2. Read only the relevant durable guidance and state: CLAUDE.md, AGENTS.md, the latest approved plan, current focus, recent log, and any existing handshake. Never inspect restricted data/raw/ content.
  3. Use the supplied outcome. If none is supplied, infer the highest-priority open loop; ask only if different choices would materially change scope.
  4. Reconcile the existing handshake. Preserve still-valid decisions and its log, then create a new handoff_id and set status: ready.
  5. Record the source and target client, source and target machine, branch, commit, exact working-tree ownership, observable acceptance criteria, real commands, and the first concrete action.
  6. Validate the YAML frontmatter and Markdown sections against the shared protocol. Check that the file contains no secrets, credentials, transcripts, caches, or restricted data.

Never overwrite project-owned CLAUDE.md or AGENTS.md: they remain durable client guidance. Never auto-commit or push the handshake.

Receive a handoff

When .context/ai-handoff.md targets the current client or either:

  1. Read both native guidance files and the handshake before editing.
  2. Compare the recorded branch, commit, machine, and changed-file ownership with the actual working tree.
  3. Set status: accepted and append a timestamped log entry before substantive work.
  4. Set status: in_progress when execution begins.
  5. Maintain acceptance criteria and the log. Finish with complete, or use blocked with the precise blocker and safe next action.

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.
