Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00058 | $0.00410 |
| Opus 5 | $0.00029 | $0.00205 |
| Sonnet 5 | $0.00012 | $0.00082 |
| Haiku 4.5 | $0.00006 | $0.00041 |
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 2d 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.
What it actually says
撰写一份交接文档，总结当前对话内容，使全新的 agent 能够无缝继续工作。
输出位置
先解析当前平台的系统临时目录，再保存为 handoff-YYYY-MM-DD-HHMM.md（用实际时间戳替换）。优先使用平台 API，例如 Python 的 tempfile.gettempdir()；在 Unix 环境可使用 $TMPDIR，未设置时回退到 /tmp。生成后告知用户完整绝对路径。
文档结构
按以下结构组织交接文档：
- 背景与目标 — 一句话概述当前任务
- 已完成工作 — 带路径/URL 引用
- 当前状态 — 进展到哪一步、卡在哪里
- 待办事项 — 下一个 agent 需要做什么
- 推荐技能 — 建议调用的 skill 列表
- 关键上下文 — 环境、分支、配置等必要信息
规则
- 不要重复已存在于其他产物（规格文档、计划、ADR、issue、commit、diff）中的内容，改为通过路径或 URL 引用。
- 脱敏处理：删除 API key、密码、个人身份信息等敏感内容。
- 如果用户传入了参数，将其视为下一次会话的重点方向，据此调整文档内容。
- 如果当前对话极短（少于 3 轮实质交流），直接告知用户无需生成交接文档，除非用户坚持。
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 feiskyer/codex-settings (236 stars, last pushed 20d ago), licensed MIT. It adds 58 tokens to every session and 410 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
