Azure Relay Skill

This skill provides expert guidance for Azure Relay. Covers troubleshooting, security, configuration, and integrations & coding patterns. 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.

Summary

This skill provides expert guidance for Azure Relay configuration, troubleshooting, security, and coding patterns. It combines a structured category index with remote documentation fetching via `mcp_microsoftdocs` or `fetch_webpage` tools, directing agents to retrieve learn.microsoft.com content on demand rather than bundling documentation directly.

Use Cases

Configure Azure Relay Hybrid Connections and WCF relays
Troubleshoot common Azure Relay connection and authentication errors
Implement Entra ID or SAS authentication for Azure Relay clients
Set up network security: IP firewall, virtual network rules, or Private Link
Build Azure Relay clients in .NET or Node.js using WebSocket APIs
Understand Azure Relay Hybrid Connections protocol for custom integrations
Configure port and firewall requirements for Azure Relay endpoints

Quality Notes

Strong: Clear category index with line ranges and descriptive headings helps agents navigate content efficiently
Strong: Explicit fallback mechanism if primary tool (mcp_microsoftdocs) is unavailable
Strong: Scope boundaries are well-defined—excludes related services (Service Bus, Event Hubs, Web PubSub, Application Gateway) by name
Moderate: Metadata freshness check ('3 months old') is good practice but no guidance on what to do if repositories are unavailable
Limitation: Line range references (L32-L57) suggest content distribution across multiple sections, but referenced files (security.md, etc.) are not present in manifest—skill is read-only and relies entirely on remote documentation
Limitation: No error handling guidance for network failures or documentation fetch timeouts
Limitation: No concrete code examples or step-by-step tutorials in the skill itself—agents must fetch all content remotely
