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 5.1 | $0.00022 | $0.00377 |
| Opus 5 | $0.00011 | $0.00188 |
| Sonnet 5 | $0.00004 | $0.00075 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
session-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 8d 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
Session Handoff（会话交接）
把有用项目状态保存在聊天上下文之外。
触发时机
以下情况使用这个 skill：
- 一个工作 session 即将结束。
- context 可能会压缩或重置。
- 另一个 agent 或人类会继续工作。
- worktree 里有有意义的未完成工作。
必读材料
AGENTS.mddocs/product.mddocs/architecture.mddocs/plans/active.mdfeature_list.jsondocs/status.mddocs/mistake-log.md- 当前改动文件或 git diff。
- 本 session 的命令输出。
流程
- 识别已完成工作。
- 识别未完成工作。
- 记录当前 feature 状态和 evidence。
- 记录已运行命令和结果。
- 记录已知失败和风险。
- 记录本 session 做过的决策。
- 运行
./scripts/clean-state.sh，或记录无法运行的原因。 - 更新
docs/status.md。 - 给出精确的建议下一步。
产出
- 更新后的 status。
- 当前 feature 状态。
- 改动文件摘要。
- 验证证据。
- 干净状态检查结果。
- 已知风险。
- 下一步动作。
边界
- 如果 worktree 有未提交改动，不要声称状态干净。
- 不要隐藏失败的检查。
- 不要让未来工作依赖私有聊天上下文。
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.

session-handoff is a skill published in the GitHub repository CadeYu/vibe-harness (5 stars, last pushed 2mo ago), licensed MIT. It adds 22 tokens to every session and 377 once invoked, about $0.0001 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 2026-08-31.
