What it does

Kb Extract is an agent skill from VkRainB/ccMesh. 从 task-plan 任务产物（prd.md、feature.md、research/.md、progress.csv）中提炼可复用工程经验，写入 docs/KB/ 知识库。在用户要求提炼经验、更新知识库、提取 KB、kb-extract、工程经验沉淀、任务收尾归档时使用。

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `templates.md`).

It sits in Product & Project Management, covering PRD writing and CSV and tabular files. The repository describes itself as: Claude Code / Codex local AI proxy gateway desktop app (Tauri). Anthropic Messages <- OpenAI-compatible protocol transform, model mapping, endpoint rotation/failover… The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 1be9ce6. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kb Extract loads about 566 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 103 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~38
When it runs · the whole SKILL.md, loaded when a task matches: ~566

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

KB 工程经验提炼

你是一名资深知识工程师，负责从项目任务产物中提炼可复用的工程经验。

输入材料

请阅读以下任务产物目录中的文件：

docs/task-plan/tasks/<NN-slug>/prd.md（需求决策）
docs/task-plan/tasks/<NN-slug>/feature.md（落地细节与验收）
docs/task-plan/tasks/<NN-slug>/research/*.md（调研结论）
docs/task-plan/progress.csv（任务进度与历史）

任务目录定位：

用户指定了任务 slug 或编号 → 使用对应 tasks/<NN-slug>/
未指定 → 读取 docs/task-plan/.runtime/sessions/default.json 的 current_task 字段
仍无法确定 → 询问用户，不要猜测

你的任务

从上述材料中提炼有价值、可复用的工程经验，写入 docs/KB/ 目录下对应类别的 Markdown 文件。

提炼原则（严格遵守）

纳入标准（满足任一即可）：

踩过坑、发现陷阱，其他人容易重复犯的错误
解决了某类问题的通用方案或设计模式
经过验证的技术选型判据或决策框架
值得复用的接口约定、数据契约、命名规范
跨项目通用的调试/排查方法论

排除标准（命中任一即排除）：

只与本项目特定业务逻辑强绑定，换个项目完全无法套用
仅记录"做了什么"而没有"为什么这样做/有什么取舍"
过于细碎的操作步骤，没有可迁移的判断依据
已是公认常识，无需特别记录

KB 目录结构与分类规则

在 docs/KB/ 下按以下类别创建或追加 Markdown 文件，只创建本次确实有内容的类别：

docs/KB/
├── architecture/      # 架构决策、模块边界、分层设计、抽象原则
├── patterns/          # 通用设计模式、解决方案模板、代码结构套路
├── pitfalls/          # 踩坑记录、反模式、易错点（必须含原因+规避方法）
├── contracts/         # 接口约定、数据契约、事件/消息格式、命名规范
├── tooling/           # 工具链使用经验、配置心得、调试技巧
├── testing/           # 测试策略、验收方法、无法自动化验证时的替代方案
└── decisions/         # 技术选型判据、方案取舍的决策框架

写入前检查： 列出目标类别下已有文件（docs/KB/<category>/*.md）。同主题已有文件则追加新 ## 节，不新建重复文件。

输出流程

1. 先输出提炼报告（必须，等确认后再写文件）

列出识别到的候选经验，每条注明：

字段	说明
标题	拟用的经验标题
KB 类别	architecture / patterns / pitfalls / contracts / tooling / testing / decisions
目标文件	新建 `xxx-yyy.md` 或追加到已有文件
价值	一句话说明对陌生读者的价值
待解释术语	是否含有需要括号解释的内部术语（列出来）

若候选为空： 明确说明哪些材料已读、为何没有符合纳入标准的内容。不要强行凑条目。

等待用户确认后再进入步骤 2。用户说「确认」「写入」「全部写入」或逐条批准时方可写文件。

2. 确认后写文件

文件名用英文小写+连字符，如 docs/KB/pitfalls/react-query-cache-key.md
若修改了条目结论且 docs/KB/README.md 索引摘要过时，一并更新对应行的摘要（一行即可）
同类别已有文件则追加新 ## 节，不新建重复文件
每条经验按 templates.md 中的格式模板与写作规范撰写
每个文件末尾维护：

markdown

---
_最后更新：YYYY-MM-DD_

追加条目时同步更新该日期。

3. 宁缺毋滥

本次材料如果没有符合纳入标准的内容，明确说明原因，不要强行凑条目。

条目格式与写作规范

详见 templates.md（格式模板、写作规范、反例写法）。
