Azure Dev Box Skill

This skill provides expert guidance for Azure Dev Box. Covers troubleshooting, best practices, decision making, 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

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.
