handoff

handoff is a skill for Codex from CassioRoos/godfly-skills. It costs 57 tokens per session (568 once invoked), scanned A, original, MIT.

A skill for writing a compact handoff document so another agent session can continue work without rebuilding the full context.

In plain words
What is it for?
It is for creating continuation notes, session summaries, resume briefs, and operational handoffs.
Why use it?
It preserves the important decisions, files, commands, risks, and next steps when work moves between sessions.

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 today.

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.

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Handoff

Write a handoff that lets a fresh agent continue without spelunking the entire conversation.

Workflow

  1. Identify what the next session will do. If the user gave a focus, tailor the handoff to that.
  2. Save the handoff outside the current repository in a durable location: ~/.codex/handoffs/ (create it if missing), named <YYYY-MM-DD>-<short-slug>.md. Never use the OS temporary directory — a handoff that must survive into a future session cannot live somewhere the OS wipes.
  3. Include only operationally useful context. Do not duplicate artifacts that already exist; reference paths, PRs, commits, docs, logs, or notebooks instead.
  4. Redact secrets, tokens, credentials, private personal data, and unnecessary customer data.
  5. Include suggested skills and why they should be used.
  6. Include exact commands already run only when they matter for continuation or verification.

Composition with toolshed

  • In-repo multi-session task state lives in docs/work/<slug>/ via the toolshed skill (thin STATE + D/Q/E). Prefer updating toolshed session-end over writing a fat handoff when the next agent will open the same repo.
  • Handoff is for off-repo or cross-machine continuation: no clone, toolshed gitignored/local-only, or a compact note outside the tree.
  • Do not re-serialize a full toolshed closeout packet into the handoff. Point at docs/work/<slug>/STATE.md, PR URLs, and SHAs.
  • Not the Workbench product/MCP (Slack/highlights app).

Rules

  • Keep it compact.
  • Prefer links, paths, commit SHAs, and command names over prose.
  • Distinguish verified facts from assumptions.
  • Say where the file was saved.
  • Suggested skills should use current names (toolshed, not workbench for task state).

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.
