Description from the maker (original English)
Progressive group routing for 524 professional skills via Rust daemon stdio shim.
These three are never merged into one score: opinions, measurements and popularity are different things.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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).
The GitHub repo last changed –, and the latest version (2.0.5) reached the registry 2 months ago.

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。
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。
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。
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" } } } }
Claude Code (stdio shim) ─┐
Claude Desktop (stdio) ├─→ Rust daemon (单进程, 单端口) → 本地 skill 仓库 Cursor / Windsurf / ... ─┘
SKILL_SHELF_ROOT 的配置各自独立,互不干扰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。
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。
search_skills 支持两种输入方式:
品牌 视觉 设计品牌设计视觉 — 自动切分为 CJK bigram,匹配精度略低于手动分词| 工具 | 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 |
| 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) |
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。
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)
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
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。
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。
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
| 变量 | 默认值 | 说明 |
|---|---|---|
SKILL_SHELF_ROOT | /data/hub | 数据根目录 |
SKILL_SHELF_SEARCH_LIMIT | 8 | search_skills 默认返回上限 |
SKILL_SHELF_MAX_RELATED_SKILLS | 5 | read_skill 返回的最大关联 skill 数 |
SKILL_SHELF_WATCH | 1 | 是否启用文件监听 |
