  • 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.

  • 3 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by yan-labs on GitHub. Read the source before you install it.

Installation

Install the Skill Link Check 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/yan-labs/yan-skills/tree/main/skill-link-check
  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.
2

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/yan-labs/yan-skills.git /tmp/yan-skills
mkdir -p .claude/skills
cp -r /tmp/yan-skills/skill-link-check .claude/skills/skill-link-check
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Skill Link Check 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 Skill Link Check 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 Skill Link Check 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.

安装与更新

来源：Skills.sh

bash
# 首次全局安装，或更新失败时重新安装
npx skills add yan-labs/yan-skills --skill skill-link-check -g -y

# 更新已安装的全局 Skill
npx skills update skill-link-check -g -y

若使用项目级安装，去掉安装命令中的 -g；项目级更新使用 npx skills update skill-link-check -p -y。

本 Skill 只审计目录布局，不自动移动、删除或覆盖文件：

  • .agents/skills/<name>/ 保存真实源文件。
  • .claude/skills 要么整体链接到 .agents/skills，要么通过逐个子项链接镜像它。

最常见的漂移是 Skill 被直接创建成 .claude/skills/<name>/ 真实目录，却没有进入 .agents/skills/。它看似已安装，实际不会随正常备份、同步或迁移流程保存。

完成条件与退出码

在 /goal 或持续执行任务里，以审计证据完整为完成条件：从目标项目运行脚本，报告每个适用作用域的布局、问题分类和退出状态。有问题时列数量、路径和建议命令；无问题时报告 clean。脚本不修改被审计目录。

  • 0：审计完成且无问题。
  • 1：审计完成且发现问题；这仍是有效结果。
  • Python traceback、参数错误或目标不可读：执行失败，查明后重跑。

运行方式

bash
python3 "$(dirname "$0")/check.py"

默认审计：

  • Project：当前目录下的 .agents/skills 与 .claude/skills。
  • Global：$HOME 下的同名目录。

自动化或 checker 可使用：

bash
# 明确指定项目，避免依赖当前工作目录
python3 "$(dirname "$0")/check.py" --project-root /path/to/project

# 只查一个作用域
python3 "$(dirname "$0")/check.py" --project-only
python3 "$(dirname "$0")/check.py" --global-only

# 输出稳定 JSON 证据；发现问题时仍返回 1
python3 "$(dirname "$0")/check.py" --json

两种合法布局

两种模式都应通过：

  1. Parent symlink：.claude/skills 本身指向 .agents/skills。新增 Skill 自动保持一致。
  2. Per-child symlinks：.claude/skills 是真实目录，每个 .claude/skills/<name> 指向 ../../.agents/skills/<name>。

脚本会自动识别模式，不要求为了统一风格而改造一个本来健康的布局。

问题分类

  • orphan-in-claude：.claude/skills/ 中有真实条目，但 .agents/skills/ 没有对应源文件。报告时优先列出。
  • missing-link：源 Skill 存在，但运行时镜像缺失。
  • not-symlink：逐子项模式下，镜像位置是重复的真实文件或目录。
  • broken-symlink：链接目标不存在，包括损坏的父级链接。
  • wrong-target：链接存在，但指向错误 Skill 或 .agents/skills 之外。

报告规则

  1. 先给总问题数和分类计数；有 orphan-in-claude 时先报告它。
  2. 每项给出名称、证据路径和一行解释。
  3. 原样附上脚本生成的建议修复命令，便于用户复核后执行。
  4. 不自动修复。孤儿目录可能是用户尚未迁移的工作，重复目录也可能已经分叉；自动移动或删除会造成数据损失。
  5. 如果全部健康，一句话说明适用作用域及布局模式即可结束。

验证 Skill 自身

bash
python3 -m unittest discover -s "$(dirname "$0")/tests" -v

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Skill Link Check AI skill do?

Use when a skill or slash command is missing, duplicated, not loading, or inconsistent between `.agents/skills` and `.claude/skills`; includes “skill 没生效”“检查 skill 链接” and broken skill links. Audits project and global skill layouts without changing them.

Why use Skill Link Check on TypingMind?

Because you install it once and use it with any model. Skill Link Check 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 Skill Link Check in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/yan-labs/yan-skills/tree/main/skill-link-check. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Skill Link Check?

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 Skill Link Check?

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

Is the Skill Link Check AI skill free?

Yes. It is published on GitHub by yan-labs under the MIT license. 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.
