How to Use This Skill

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
