How to Use This Skill

如何使用本技能

IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g., 
L35-L120
), use 
read_file
with the specified lines. For categories with file links (e.g., 
[security.md](security.md)
), use 
read_file
on the linked reference file
IMPORTANT for Agent: If 
metadata.generated_at
is more than 3 months old, suggest the user pull the latest version from the repository. If 
mcp_microsoftdocs
tools are not available, suggest the user install it: Installation Guide
This skill requires network access to fetch documentation content:
  • Preferred: Use 
    mcp_microsoftdocs:microsoft_docs_fetch
    with query string 
    from=learn-agent-skill
    . Returns Markdown.
  • Fallback: Use 
    fetch_webpage
    with query string 
    from=learn-agent-skill&accept=text/markdown
    . Returns Markdown.
Agent 重要提示：使用下方的分类索引查找相关章节。对于带有行范围的分类（例如 
L35-L120
），使用
read_file
读取指定行内容。对于带有文件链接的分类（例如 
[security.md](security.md)
），使用
read_file
读取链接的参考文件
Agent 重要提示：如果
metadata.generated_at
已超过3个月，建议用户从仓库拉取最新版本。如果
mcp_microsoftdocs
工具不可用，建议用户安装该工具：安装指南
本技能需要网络访问权限以获取文档内容：
  • 首选方式：使用
    mcp_microsoftdocs:microsoft_docs_fetch
    ，并携带查询字符串
    from=learn-agent-skill
    ，返回Markdown格式内容。
  • 备用方式：使用
    fetch_webpage
    ，并携带查询字符串
    from=learn-agent-skill&accept=text/markdown
    ，返回Markdown格式内容。
