Common questions

Is Skill Shelf (Rust singleton daemon) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.5) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

Skill Shelf

上千个专业技能,只占 context 7 个工具定义。

给 AI agent 装 skill,最痛的问题是:skill 越多,context 越胖。每个 skill 的 description 常驻上下文,几百个 skill 就是几万 tokens 白白浪费,每次对话都背着跑。开多个客户端还各跑各的进程,内存翻倍。更烦的是,装了一堆 skill 自己都记不住哪个是干嘛的、哪些真的好用哪些是花架子,最后还是全靠人去翻文档。

Skill Shelf 连这个问题一起解决了:LLM 看见 MCP 工具就会自己去查、自己去用。你不需要记住每个 skill 的内容,也不需要判断什么时候该用——LLM 遇到合适的场景自己会去搜索和加载。

Skill Shelf 的解法:skill 全部存本地仓库,context 里只有 7 个工具定义。需要时搜索加载,不需要时零开销。Rust 单例 daemon,一个进程服务所有 MCP 客户端——Claude Code、Codex、Cursor、Windsurf 同时开也只有一个后台进程。

不只是用内置的几百个 skill 和 group。工作中积累的经验、踩过的坑、反复用的工作流,都可以整理成 skill 入库——一份 Markdown 文件就是一个 skill。内置的 18 个组不够用就自己建,manage_group 创建自定义分组,install_skills 批量入库。把自己团队的 know-how 变成可复用的 skill 库。

安装

从 GitHub Release 使用

下载与你的平台匹配的 release 包并解压:

skill-shelf-vX.Y.Z-windows-x64.zip

skill-shelf-vX.Y.Z-windows-arm64.zip skill-shelf-vX.Y.Z-linux-x64.tar.gz skill-shelf-vX.Y.Z-linux-arm64.tar.gz skill-shelf-vX.Y.Z-macos-x64.tar.gz skill-shelf-vX.Y.Z-macos-arm64.tar.gz

MCP 客户端配置:

{

"mcpServers": { "skill-shelf": { "command": "node", "args": ["D:/Tools/Skill-Shelf/bin/skill-shelf.js", "mcp"] } } }

release 包已经内置对应平台的 Rust daemon 二进制,不需要安装 Rust 或执行 cargo build。

从源码使用
git clone https://github.com/halflifezyf2680/Skill-Shelf.git

cd Skill-Shelf npm install npm run rust:build

MCP 客户端配置:

{

"mcpServers": { "skill-shelf": { "command": "node", "args": ["D:/AI_Project/Skill-Shelf/bin/skill-shelf.js", "mcp"] } } }

也可以先 npm link,再使用 npm bin:

npm link
{

"mcpServers": { "skill-shelf": { "command": "skill-shelf", "args": ["mcp"], "cwd": "/your/path/to/Skill-Shelf" } } }

支持 Claude Code(~/.claude.json)、Claude Desktop(claude_desktop_config.json)、Cursor、Windsurf 等所有 MCP 兼容客户端。每个客户端各自启动一个 stdio shim,共享同一个 daemon 进程。

首次调用时 stdio shim 会自动拉起 Rust daemon。多个 MCP 客户端会共享同一个 daemon,不需要分别管理后台进程。

使用

配置完成后,在 MCP 客户端里先调用:

browse_shelf()

正常结果应包含:

{

"groupsCount": 18, "totalSkills": 524, "watcherStatus": { "running": true } }

常用流程:

browse_shelf()

→ 看到 group catalog → browse_shelf(group="marketing", limit=10) → read_skill(skill="微信公众号运营")

如果不知道该进哪个组,直接搜索:

search_skills(query="运营 用户 增长 活动 社群 内容 数据", limit=10)

安装自己的 skill 包:

install_skills(sourcePath="/path/to/my-skills")

validate_skills()

如果你希望把 skill 库放到包目录以外的位置,设置 SKILL_SHELF_ROOT。例如:

{

"mcpServers": { "skill-shelf": { "command": "node", "args": ["D:/AI_Project/Skill-Shelf/bin/skill-shelf.js", "mcp"], "env": { "SKILL_SHELF_ROOT": "D:/SkillShelf/hub" } } } }

架构

Claude Code (stdio shim) ─┐

Claude Desktop (stdio) ├─→ Rust daemon (单进程, 单端口) → 本地 skill 仓库 Cursor / Windsurf / ... ─┘

  • 单进程: 整个仓库只有一个 Rust daemon 在跑,不会因为开多个客户端就跑出几十个 Node 进程
  • stdio shim: 每个 MCP 客户端启动一个极轻量的 shim 进程(只做 stdin↔IPC 转发),真正的业务逻辑全在 daemon 里
  • 共享状态: 所有客户端共享同一个 skill 索引和缓存,热重载一次全局生效
  • workspace 隔离: 不同 SKILL_SHELF_ROOT 的配置各自独立,互不干扰

路由协议

browse_shelf()                ← Level 1: group catalog(name + description + count)

│ ├─ 选定 group → browse_shelf(group="engineering") → skill summaries │ ├─ 选定 skill → read_skill(skill) → 默认返回 summary │ └─ 需要全文 → read_skill(skill, full=true) │ └─ 组路由不足时 → search_skills(query) 作为兜底 │ ▼ search_skills(query) ← fallback: 直接按关键字兜底定位

先看组,再看组内 skill,最后才用 search_skills 兜底。

语言策略

搜索会先用用户语言尝试,没结果时再换英文重试。skill 作者无需为每个 skill 写多语言 description。

中文搜索

search_skills 支持两种输入方式:

  1. 空格分词(推荐):品牌 视觉 设计
  2. 连续输入(兜底):品牌设计视觉 — 自动切分为 CJK bigram,匹配精度略低于手动分词

工具清单(7 个)

只读
工具用途
browse_shelf不传参返回 group catalog + 状态信息;传 group 返回组内 skill summaries
search_skills兜底搜索全部 skill,返回 top N 匹配结果
read_skill默认读取 skill summary;full=true 时读取完整正文、资源、参考文件
写操作
工具用途
install_skills从目录安装 skill 包(支持新建和 LLM 辅助分组)
validate_skills校验完整性;clean=true 时自动删除有问题的 skill
manage_group创建/更新/删除存储组(mode: create/update/delete)
reclassify_skill将 skill 移至新的组(更新 frontmatter + 移动目录 + 重建索引)

组体系

18 个内置组:

engineering · design · product · project-management · marketing · paid-media · sales · finance · legal-compliance · hr-talent · support-operations · supply-chain · academic-research · testing-qa · spatial-gaming · specialized-domain · game-studios · creative-media

安装 skill 时,如果 SKILL.md frontmatter 未指定 group,工具会返回 skill 描述和可用组列表,由 LLM 选择最合适的组。

存储结构

data/hub/

config/groups.json # 组定义(18 个内置组 + 自定义组) packages/{group}/{skill-id}/ SKILL.md # skill 正文(必须) meta.json # 自动生成的元数据 references/ # 可选参考文件 scripts/ # 可选辅助脚本 assets/ # 可选资源文件 staging/imports/ # 待审查的导入候选 index/ # 索引文件(运行时自动维护)

Skill 包格式

每个 skill 是一个包含 SKILL.md 的目录:

---

name: my-skill description: 这个 skill 做什么 group: engineering


My Skill

Skill 正文内容...

name 和 description 是必填 frontmatter 字段。group 可选,不填时由 LLM 在安装时分类。

热重载

daemon 启动时自动监听 packages/ 目录变更,新增、修改、删除 skill 后索引自动更新,无需重启。

CLI 命令

skill-shelf mcp      # 启动 stdio shim(MCP 客户端调用)

skill-shelf daemon # 启动/连接 daemon skill-shelf status # 查看 daemon 状态 skill-shelf stop # 停止 daemon

环境变量

变量默认值说明
SKILL_SHELF_ROOT /data/hub数据根目录
SKILL_SHELF_SEARCH_LIMIT8search_skills 默认返回上限
SKILL_SHELF_MAX_RELATED_SKILLS5read_skill 返回的最大关联 skill 数
SKILL_SHELF_WATCH1是否启用文件监听
