Lists multiple specific concrete capabilities: object storage, SMB file shares, async messaging, NoSQL key-value, big data analytics, access tiers, and lifecycle management across five named Azure Storage services.

Clearly answers both 'what' (Azure Storage Services with specific capabilities) and 'when' (explicit USE FOR and DO NOT USE FOR clauses with trigger terms and routing guidance to other skills).

Excellent coverage of natural terms users would say: 'blob storage', 'file shares', 'queue storage', 'table storage', 'data lake', 'upload files', 'download blobs', 'storage accounts', 'access tiers', 'lifecycle management'. These are terms users would naturally use when working with Azure Storage.

Highly distinctive with explicit DO NOT USE FOR boundaries that route SQL databases, Cosmos DB, Event Hubs, and Service Bus to other specific skills, minimizing conflict risk with related Azure skills.

Generally efficient with good use of tables, but has some redundancy—the 'Azure SDKs' section at the bottom largely repeats the 'SDK Quick References' section above it. The redundancy options and storage account tiers tables, while informative, contain reference information Claude likely already knows.

Provides concrete, copy-paste-ready CLI commands with clear parameter placeholders, specific MCP tool commands with exact command names, and direct links to SDK guides per language. The guidance is immediately executable.

The skill is primarily a reference/lookup skill rather than a multi-step workflow, so complex sequencing isn't strictly required. However, there are no validation steps for operations like uploads/downloads (e.g., verifying upload success, checking blob existence before download), and no error handling guidance for common failure modes.

Excellent progressive disclosure with a clear overview in the main file, well-organized SDK references split by service and language pointing to separate files, and external documentation links for deep dives. All references are one level deep and clearly signaled.
