Covers best practices, decision making, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.89## How to Use This Skill1011> **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 file1213This skill requires **network access** to fetch documentation content:14- **Preferred**: Use `mcp_microsoftdocs:microsoft_docs_fetch`. Returns Markdown.15- **Fallback**: Use `WebFetch`. Returns Markdown.1617## Category Index1819| Category | Lines | Description |20|----------|-------|-------------|21| Best Practices | L30-L51 | End-to-end Azure security hardening guidance: identity,
