  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by crane-in-clear-sky on GitHub. Read the source before you install it.

Installation

Install the Marketplace Skill Installer AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/crane-in-clear-sky/WorkWit-AI-Agent/tree/main/workwit/backend/builtin_skills/marketplace_skill_installer
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/crane-in-clear-sky/WorkWit-AI-Agent.git /tmp/WorkWit-AI-Agent
mkdir -p .claude/skills
cp -r /tmp/WorkWit-AI-Agent/workwit/backend/builtin_skills/marketplace_skill_installer .claude/skills/marketplace_skill_installer
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Marketplace Skill Installer in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Marketplace Skill Installer on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Marketplace Skill Installer is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

⚠️ 环境适配:本技能面向 WorkBuddy 技能推荐市场(BuiltinMarket),当前系统的技能广场即对应能力——技能创建用元工具 create_skill,技能浏览用 list_skills。

Marketplace Skill Installer

帮助用户用一句话从 WorkBuddy 推荐市场(BuiltinMarket)安装 Skill。

When to Use

只要用户表达"安装某个技能/skill"的意图就用此 Skill,例如:

  • 「帮我安装飞书套件」
  • 「安装一个 lark-unified 的 skill」
  • 「我想用 X 技能,帮我装下」
  • 「install Y skill」

严格的工具调用约束

  • 禁止直接构造任何 HTTP 请求,禁止涉及 token/cookie/Authorization。
  • 只能通过 workbuddy_marketplace_skill 这个内置工具完成全部操作;鉴权和后端调用由宿主处理。
  • 禁止伪造或猜测 skillId——必须从 search 结果中拿到。

Workflow

Step 1:识别关键字

从用户输入中抽取一个搜索 keyword:

  • 如果用户说了显示名(例:"飞书套件"),用显示名;
  • 如果用户说了技术名(例:"lark-unified"),用技术名;
  • 既没说显示名也没说技术名(仅说"装个 skill")→ 礼貌追问"想安装哪个技能?可以告诉我名字或关键字"。

Step 2:搜索

调用 workbuddy_marketplace_skill,action 为 search:

limit 一般保持默认 5,必要时可上调到 10–20。

返回字段说明:

  • success: false → 把 error 透传给用户,停下;
  • results: [](空数组)→ 告诉用户"未在推荐市场找到匹配的 skill",停下;
  • results.length === 1 → 直接进入 Step 3;
  • results.length >= 2 → 进入 Step 4 让用户挑。

Step 3:单一命中

逻辑分支(r = results[0]):

  • 未安装(r.installed === false)→ 直接调 install:
  • 已安装且已是最新(r.installed === true && r.updateAvailable === false)→ 告诉用户"该 Skill 已是最新版本 v<r.version>,无需重复安装",停下;
  • 已安装且有新版(r.installed === true && r.updateAvailable === true)→ 询问用户"已安装 v<r.installedVersion>,最新版本是 v<r.version>,是否更新?"。用户同意后再调 install。

⚠️ 不要自己用字符串相等判断版本新旧;updateAvailable 字段已用 semver 计算好。

Step 4:多命中

把 results 列出来让用户选。展示时只展示 name、version、description 的前 60 字、是否 installed。不要把 skillId 透露给用户——那是机器内部 id。例:

用户选定后取对应 results[i].skillId,按 Step 3 的分支处理。

Step 5:调用 install 后

workbuddy_marketplace_skill 的 install action 返回:

  • success: true → 用 message 告诉用户安装到了哪里、版本是什么;可附一句"在【技能管理】面板里能看到它"。不要手动构造路径——直接用 message 字段。
  • success: false → 把 error 透传,并按错误类型给提示(见下表)。

常见错误透传

error 前缀含义建议提示
[CONFIG_ERROR]主进程未配置 endpoint"WorkBuddy 推荐市场暂未启用,可能需要更新到最新版客户端"
[BUILTIN_MARKET_ERROR]后端业务错误直接展示 error 内容
[UNKNOWN_SKILL_ID]install 阶段发现该 skillId 在推荐市场已不存在不要重试相同的 skillId;重新调 search 拿新的 skillId 再安装
[DOWNLOAD_ERROR]下载签名 URL 或 zip 失败"下载失败,可能是网络问题或权限不足"
[EXTRACT_ERROR]解压失败"解压安装包失败,建议清理 $WORKBUDDY_CONFIG_DIR/skills/(默认 ~/.workbuddy/skills/)后重试"
[INSTALL_ERROR]其他未知直接展示 error 内容

重要规则

  • 鉴权全部由宿主处理,不要让用户提供 token / cookie / 任何 header。
  • 不要主动列举所有可用的 skill——只在用户明确想看时才用 search 拉。
  • 安装成功后不要自我开启该 Skill,也不要尝试直接调用它的工具——让用户自己启用。
  • 除了上述工具,本 Skill 不应触发 Bash、文件写入或网络请求。

Frequently asked questions

What does the Marketplace Skill Installer AI skill do?

Why use Marketplace Skill Installer on TypingMind?

Because you install it once and use it with any model. Marketplace Skill Installer is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Marketplace Skill Installer in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/crane-in-clear-sky/WorkWit-AI-Agent/tree/main/workwit/backend/builtin_skills/marketplace_skill_installer. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Marketplace Skill Installer?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Marketplace Skill Installer?

As many as you like. As long as a model supports skills, you can use Marketplace Skill Installer with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Marketplace Skill Installer AI skill free?

It is published on GitHub by crane-in-clear-sky. Check the repository for licensing terms. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
