A test case the skill fixed. Same model, same prompt, with and without the skill.
We have a large multi-tenant registry where team A should only have read/write access to repository path `teams/team-a/*` and team B to `teams/team-b/*`. Standard Azure RBAC at registry resource scope is too broad. How can we grant granular repository-level permissions in ACR?

| Recommends configuring Azure ABAC repository permissions to grant path-level access. | Missed | Passed |
| Explains how scoping permissions to specific repository paths restricts access within a shared registry. | Passed | Passed |

This skill provides expert guidance for Azure Container Registry. 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.
IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g.,
L35-L120), useread_filewith the specified lines. For categories with file links (e.g.,[security.md](security.md)), useread_fileon the linked reference file
IMPORTANT for Agent: If
metadata.generated_atis more than 3 months old, suggest the user pull the latest version from the repository. Ifmcp_microsoftdocstools are not available, suggest the user install it: Installation Guide
This skill requires network access to fetch documentation content:
mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.| Category | Lines | Description |
|---|---|---|
| Troubleshooting | L37-L52 | Diagnosing and fixing ACR issues: health checks, error codes, login/auth, network, performance, transfer, logs, artifact cache/streaming, Arc extension, and customer-managed keys. |
| Best Practices | L53-L60 | Best practices for ACR operations: managing public image dependencies, safe image deletion and storage cleanup, and robust image tagging/versioning strategies. |
| Decision Making | L61-L67 | Guidance on choosing Kubernetes auth methods for ACR, deciding geo-replication strategy, and migrating image signing from Docker Content Trust to Notary Project |
| Architecture & Design Patterns | L68-L73 | Patterns for ACR performance and governance: caching image pulls, geo-replication strategies, connected registries for edge/offline, and gated import workflows for public images. |
| Limits & Quotas | L74-L79 | Details on ACR SKUs (Basic/Standard/Premium) feature differences, performance and throughput limits, and how image storage capacity and quotas are calculated and enforced. |
| Security | L80-L118 | Securing ACR access: auth methods (Entra, managed identity, tokens), RBAC/ABAC, network/firewall/VNet rules, policy/compliance, encryption keys, image signing/verification, and Defender scanning. |
| Configuration | L119-L139 | Configuring ACR behavior: caching, retention/soft delete, purge, locks, IPv6, metrics/logs, webhooks, and setting up/automating ACR Tasks (YAML, timers, agent pools, patching). |
| Integrations & Coding Patterns | L140-L157 | Integrating ACR with Kubernetes, ACI, GitHub Actions, ORAS, Helm, and webhooks; configuring auth, caching, transfers, image builds, and Notation-based signing/verification. |
| Deployment | L158-L162 | Using ARM templates to automate ACR quick tasks and data transfer, and deploying/managing ACR connected registries via Azure Arc extension |
