Azure Cosmos DB Skill

This skill provides expert guidance for Azure Cosmos DB. 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 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 Cosmos DB across all APIs (NoSQL, MongoDB, Cassandra, PostgreSQL, Gremlin, Table) and covers troubleshooting, best practices, decision-making, architecture patterns, limits/quotas, security, configuration, integrations, and deployment. It combines a structured category index with remote documentation fetching capabilities using Microsoft Docs and webpage fetch tools, enabling agents to deliver comprehensive Cosmos DB expertise with up-to-date Microsoft Learn content.

Use Cases

  • Troubleshoot Cosmos DB connectivity, performance, and error codes across APIs
  • Guide multi-region replication and high-availability design decisions
  • Advise on partitioning, indexing, and RU optimization strategies
  • Explain consistency levels, conflict resolution, and backup/restore options
  • Design AI/RAG and vector search implementations on Cosmos DB
  • Support migration planning from MongoDB, Cassandra, PostgreSQL, or DocumentDB
  • Configure security controls including RBAC, encryption, CMK, and network isolation
  • Select appropriate throughput modes, scaling options, and pricing strategies

Quality Notes

  • Excellent breadth: covers all Cosmos DB APIs (NoSQL, Mongo, Cassandra, Gremlin, PostgreSQL, Table, DocumentDB) and all operational domains
  • Well-structured category index with line ranges for in-file navigation and file links for external reference files
  • Clear scope boundaries: explicitly excludes Azure Table Storage, SQL Database, MySQL, and PostgreSQL managed services
  • Comprehensive topic reference with 400+ Microsoft Learn URLs organized by category, enabling agents to fetch targeted documentation
  • Supporting files (integrations.md, deployment.md, configuration.md) are present and properly linked
  • Smart fallback mechanism: recommends mcp_microsoftdocs first, then fetch_webpage, then suggests manual intervention if tools unavailable
  • Metadata staleness check built in: agents are instructed to suggest user pull latest version if generated_at exceeds 3 months
  • Well-documented exclusions prevent scope creep and confusion with other Azure database services
