azure-storage
Azure Storage Services including Blob Storage, File Shares, Queue Storage, Table Storage, and Data Lake. Answers questions about storage access tiers (hot, cool, cold, archive), when to use each tier, and tier comparison. Provides object storage, SMB file shares, async messaging, NoSQL key-value, and big data analytics. Includes lifecycle management. USE FOR: blob storage, file shares, queue storage, table storage, data lake, upload files, download blobs, storage accounts, access tiers, storage tiers, hot cool cold archive, storage tier comparison, when to use storage tiers, lifecycle management, Azure Storage concepts. DO NOT USE FOR: SQL databases, Cosmos DB (use azure-prepare), messaging with Event Hubs or Service Bus (use azure-messaging).

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that covers all evaluation dimensions well. It provides specific capabilities, comprehensive trigger terms, explicit 'USE FOR' and 'DO NOT USE FOR' clauses, and clear boundaries that distinguish it from related Azure skills. The description is thorough without being unnecessarily verbose.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions and capabilities: Blob Storage, File Shares, Queue Storage, Table Storage, Data Lake, access tiers (hot, cool, cold, archive), lifecycle management, object storage, SMB file shares, async messaging, NoSQL key-value, and big data analytics. | 3 / 3 |
Completeness | Clearly answers both 'what' (Azure Storage Services with specific sub-services and capabilities) and 'when' (explicit 'USE FOR' clause with trigger terms, plus a 'DO NOT USE FOR' clause that further clarifies boundaries). The explicit trigger guidance is thorough. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'blob storage', 'file shares', 'queue storage', 'upload files', 'download blobs', 'storage accounts', 'access tiers', 'hot cool cold archive', 'storage tier comparison', 'lifecycle management'. These are terms users would naturally use when asking about Azure Storage. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear boundaries. The 'DO NOT USE FOR' clause explicitly redirects SQL databases, Cosmos DB, Event Hubs, and Service Bus to other skills, significantly reducing conflict risk. The focus on Azure Storage services is a clear niche. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured Azure Storage reference skill that effectively uses tables for quick lookup and provides concrete CLI commands and MCP tool references. Its main weaknesses are minor redundancy between the SDK sections and lack of error handling/validation guidance for storage operations. The progressive disclosure pattern with language-specific SDK references is particularly well done.
Suggestions
Remove the duplicate 'Azure SDKs' section at the bottom since 'SDK Quick References' already covers the same content with more detail.
Add brief error handling notes for common storage operations (e.g., what to do when blob download fails, how to handle auth errors).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | 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 useful, include information Claude likely already knows about Azure. | 2 / 3 |
Actionability | Provides concrete, copy-paste ready CLI commands with clear parameter placeholders, specific MCP tool commands with exact command names, and well-organized reference links to SDK guides for multiple languages. The guidance is immediately executable. | 3 / 3 |
Workflow Clarity | The skill is primarily a reference/lookup skill rather than a multi-step workflow, so explicit validation steps are less critical. However, the MCP vs CLI fallback path is clear, and the content is well-sequenced from listing accounts to containers to blobs. No validation or error handling guidance is provided for operations like uploads/downloads. | 2 / 3 |
Progressive Disclosure | Excellent progressive disclosure with a concise overview in the main file and well-signaled one-level-deep references to SDK guides per language, external Microsoft documentation, and a centralized SDK usage guide. Navigation is clear and organized. | 3 / 3 |
