Azure Key Vault Skill

This skill provides expert guidance for Azure Key Vault. Covers troubleshooting, best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.

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 readfile with the specified lines. For categories with file links (e.g., [security.md](security.md)), use readfile on the linked reference file

IMPORTANT for Agent: If metadata.generatedat is more than 3 months old, suggest the user pull the latest version from the repository. If mcpmicrosoftdocs tools are not available, suggest the user install it: Installation Guide

This skill requires network access to fetch documentation content:

Preferred: Use mcpmicrosoftdocs:microsoftdocs_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.
