What is document-lifecycle-guard?

A rule for keeping each development role's core documents in one maintained location instead of creating parallel versions.

Use it to manage role-specific folders, update documents in place, record changes, initialise missing files, and preserve old versions after major revisions.

It prevents scattered documents, outdated copies, and unclear ownership of project information.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00087	$0.02020
Opus 5	$0.00044	$0.01010
Sonnet 5	$0.00017	$0.00404
Haiku 4.5	$0.00009	$0.00202

Security

Grade A, and why

document-lifecycle-guard 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 7d 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.

文档生命周期守门规则（document-lifecycle-guard）

核心原则：文档不是「为这次任务新建的」，而是「被这次任务更新了」。一个项目中，每类核心文档永远只有一份——不断演化，不断增厚，不创建平行版本。

每个角色的文档领地

每个角色在项目中有且仅有一个文件夹，这是它的唯一文档领地：

角色	文件夹	核心文档（最多3个）	追踪台
产品经理	`产品经理/`	产品定义.md / 开发计划.md	产品问题追踪台.md
技术架构师	`技术架构师/`	技术架构.md	技术问题追踪台.md
测试工程师	`测试工程师/`	test-spec.md / 主测试文档.md	—
DevOps	`DevOps/`（或项目根目录）	DEPLOY_ARCH.md	—
内部总控（跨角色）	`内部总控/`	修复记录.md	—

文档管理铁律（所有角色必须遵守）

铁律 1：自建不等待

激活任何角色时，执行：
  Glob: 项目群/[项目]/[角色文件夹]/*.md
  
  IF 文件夹不存在 OR 核心文档缺失：
    → 立即创建（见「标准初始化模板」）
    → 不需要用户授权，不需要等待
    → 输出：「📁 已初始化 [角色] 文档领地」

铁律 2：in-place 更新，禁止创建平行版本

✅ 正确：打开 产品定义.md → 找到相关章节 → 修改内容 → 更新版本号 → 追加变更记录
❌ 禁止：创建 产品定义_v2.md / 产品定义_新版.md / 产品定义_20260325.md
❌ 禁止：创建 技术架构_修改版.md
❌ 禁止：同一角色文件夹下有超过3个核心文档（追踪台不计）

判断方法：
  IF 你想创建一个文件名含「v2/新版/修改版/副本/temp」的文档 → 停止，改为更新原文档

铁律 3：所有核心文档必须有变更记录

每个核心文档底部必须有：

## 变更记录

| 版本 | 日期 | 修改内容 | 修改原因 |
|------|------|---------|---------|
| v1.0 | 初始日期 | 初始创建 | — |
| v1.1 | 修改日期 | [改了什么] | [为什么改] |

每次修改文档，必须在此表追加一行。不可省略。

铁律 4：重大改版先存旧版

判断标准：满足任一条 → 视为「重大改版」
  □ 修改内容超过文档总量的 30%
  □ 删除了已有章节
  □ 更改了核心数据结构/接口定义
  □ 产品定位/技术方向发生调整

重大改版流程：
  Step 1: 将当前版本复制到 history/ 子目录
    命名：[文件名]_v[当前版本]_[YYYYMMDD].md
    示例：产品定义_v1.2_20260325.md
  Step 2: 修改原文件内容
  Step 3: 更新版本号
  Step 4: 追加变更记录

IF 只是小改动（修正措辞/补充细节/修复错误描述）→ 不需要存旧版，直接改

铁律 5：追踪台文件 append-only

产品问题追踪台.md / 技术问题追踪台.md / 修复记录.md：
  ✅ 只追加行，不删除行
  ✅ 解决后更新「状态」列为「已解决」
  ❌ 不删除已解决的条目（需要历史追溯）
  ❌ 不需要存旧版（本身就是历史记录）

标准初始化模板

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.

document-lifecycle-guard is a cursor rule published in the GitHub repository TashanGKD/tashan-cursor-skills (20 stars, last pushed 5mo ago), licensed MIT. It adds 87 tokens to every session and 2,020 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.
