One of 8 test cases the skill fixed. Same model, same prompt, with and without the skill.
A client demands that write operations to Azure Blob Storage supply an explicit AES-256 encryption key in the request headers for each blob write, rather than relying solely on platform-managed or Key Vault Key-managed account keys. What encryption feature satisfies this requirement, and what is its documentation URL?
| Checked | Without skill | With skill |
|---|---|---|
| Identifies Customer-Provided Keys (CPK) as the mechanism for passing encryption keys in HTTP request headers. | Passed | Passed |
| Includes the official documentation URL https://learn.microsoft.com/en-us/azure/storage/blobs/encryption-customer-provided-keys for customer-provided keys guidance. | Missed | Passed |

| Troubleshooting | L36-L48 | Diagnosing and fixing Azure Blob Storage issues: Storage Mover errors/networking, support bundles, BlobFuse/BlobFuse2 mount & I/O problems, metrics/logging quirks, NFS 3.0, and SFTP limitations. |
| Best Practices | L49-L84 | Performance, reliability, and cost-optimization guidance for Azure Blob/Data Lake: access tiers, lifecycle, hot partitions, NFS/SFTP, client tuning, retries, monitoring, and backup best practices. |
| Decision Making | L85-L114 | Cost and pricing guidance for Azure Blob and related storage: choosing tiers, connectivity, migration tools, data protection, SFTP/BlobFuse options, and estimating transfer, archive, and multi-region costs. |
| Limits & Quotas | L115-L134 | Limits, quotas, performance, and known issues for Blob Storage features (tiers, lifecycle, replication, NFS/SFTP, static sites, premium accounts, tools like BlobFuse and Storage Mover). |
| Security | L135-L196 | Securing Blob Storage: identity-based access (RBAC/ABAC, Entra ID), SAS tokens, SFTP, encryption (CSE, CPK, scopes), ACLs, WORM, anonymous access controls, and Storage Mover security. |
| Configuration | L197-L256 | Configuring monitoring, lifecycle, immutability, networking, mounts (BlobFuse/NFS), inventory, restore/versioning, and third‑party backup/migration tools for Azure Blob Storage. |
| Integrations & Coding Patterns | L257-L381 | SDK and CLI patterns for integrating with Blob and ADLS Gen2: connect, upload/download, copy, list, manage containers/blobs/leases/metadata/tags/tiers, events, SAS, mounts, and migration/inventory workflows. |
| Deployment | L382-L394 | Guides for deploying static websites on Blob Storage, enabling Data Lake features, and migrating data from on-prem, AWS, and third‑party NAS solutions into Azure Storage. |
