vesti-handoff

vesti-handoff is a skill for Claude Code, Codex from firefly-hefeng/VESTI-SKILLS. It costs 74 tokens per session (1,227 once invoked), scanned A, original, MIT.

A structured handoff format for passing a coding task to another AI or session. It records the goal, completed work, files, decisions, failed approaches, verification, and next steps.

In plain words
What is it for?
Use it when compacting a session, switching tools, transferring unfinished work, or preparing instructions for another coding agent.
Why use it?
It preserves important project context when a task changes hands and tells the next agent to rerun the latest check before trusting the summary.

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

vesti-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 12d 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.

VESTI Handoff V2 — 结构化工作交接(含接手先验证规则)

把当前工作压缩为下一会话/另一个 AI 可直接接手的交接文档。清单类信息(文件、命令、git 状态)从真实记录提取,不凭印象罗列;叙事类由你归纳。

V2 格式(与 VESTI-APP Relay Pack 对齐)

{
  "meta": { "version": 2, "createdAt": "<ISO 8601>", "conversationCount": 1 },
  "goal": "可检验的目标(一两句)",
  "state": {
    "completed": ["已完成事项 + 证据锚点"],
    "inProgress": ["进行中事项 + 停在哪一步"],
    "blocked": ["被阻塞事项 + 阻塞原因"]
  },
  "files": [
    { "path": "真实碰过的文件路径", "why": "为什么重要", "last_state": "目前改动状态" }
  ],
  "decisions": [
    { "decision": "做了什么决定", "rationale": "理由 + 否决的替代方案" }
  ],

    { "approach": "试过的方案", "whyFailed": "失败原因", "evidence": "上下文中的证据位置" }
  ],
  "verification": {

交接文档结构(Markdown 可读版本,按此顺序)

# 交接:<任务一句话>
> 另一个 AI 产出了以下工作摘要。请在已有基础上继续,避免重复劳动。
> **在采信最后的结论之前,先回到「验证」一节重新跑一遍最后一条验证命令,确认无误后再继续。**

## 目标(Goal)
做完是什么样(一两句,可检验)。

## 状态(State)
### 已完成(Completed)
- 每条带证据锚点:文件路径 / 命令输出 / 会话引用。

### 进行中(In Progress)
- 当前停在哪一步、为什么。

### 被阻塞(Blocked)
- 哪些事项因未解决的依赖而无法推进。

## 关键决策(Key Decisions)
- 选了什么 + 否决了什么 + 原因。

## 关键文件(Key Files)
| 路径 | 为什么重要 | 最后状态 |
(从工具调用/编辑记录确定性提取,禁止虚构;每条带来源)

## 失败死路(Failed Paths)
- 试过什么 → 结果如何 → 为什么放弃。(最贵、最易丢的一段,必须保留)
- 每条附带证据位置(哪个会话/消息显示了该失败)

## 验证(Verification)
- 最后执行的验证命令 + 最近一次实际结果(时间)。
- 标注通过/失败状态。接手方第一条必须重跑。

## 下一步(Next Steps)
- 每条自包含、离开本聊天也能执行;第一条 = 重跑验证。

## 置信度
- 整体 0-100% + 低置信区域(哪些部分需要接手方重点复核)。

## 环境(Environment)
- Git 分支/远程、Node/包管理版本等可重现的环境信息。

守则

  • 接手先验证:无论交接方多可信,先把「验证」节最后一条命令重跑一遍——"报告说完成"不等于完成。
  • 失败尝试与否决原因完整保留,不许美化成"一切顺利";每条致命 evidence 指向上下文中的证据。
  • 文件清单只列真实碰过的(编辑/读取/引用);不确定的条目标「待核实」。
  • 阻塞项与进行中区分:因依赖未满足而无法推进的标为 blocked,正在做的标为 inProgress。
  • 决策要写否决方案:不光写做了什么决定,还要写否决了哪些替代方案及原因。
  • 交接文档本身落盘(如 HANDOFF.md 或交给 VESTI 沉淀区),不要只存在于对话里。
  • V2 JSON 格式与 VESTI-APP Relay Pack 对齐,确保机器可读。

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.

vesti-handoff is a skill published in the GitHub repository firefly-hefeng/VESTI-SKILLS (190 stars, last pushed today), licensed MIT. It adds 74 tokens to every session and 1,227 once invoked, about $0.0004 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.
