entra-app-registration
Guides Microsoft Entra ID app registration, OAuth 2.0 authentication, and MSAL integration. USE FOR: create app registration, register Azure AD app, configure OAuth, set up authentication, add API permissions, generate service principal, MSAL example, console app auth, Entra ID setup, Azure AD authentication. DO NOT USE FOR: Azure RBAC or role assignments (use azure-rbac), Key Vault secrets (use azure-keyvault-expiration-audit), general Azure resource security guidance.

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 strongly. It provides specific capabilities, comprehensive trigger terms covering both legacy and current Azure naming, explicit use/don't-use guidance, and clear boundary delineation with related skills. The DO NOT USE FOR clause with skill redirects is a particularly effective pattern for reducing conflict risk.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: app registration, OAuth 2.0 authentication, MSAL integration, API permissions configuration, service principal generation, and console app auth. These are clearly defined capabilities. | 3 / 3 |
Completeness | Clearly answers both 'what' (guides Entra ID app registration, OAuth 2.0, MSAL integration) and 'when' (explicit USE FOR clause with trigger terms). Additionally includes DO NOT USE FOR guidance with alternative skill references, which further strengthens routing clarity. | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural terms users would say: 'create app registration', 'register Azure AD app', 'configure OAuth', 'set up authentication', 'MSAL example', 'Entra ID setup', 'Azure AD authentication'. Covers both old (Azure AD) and new (Entra ID) naming conventions. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche (Entra ID/OAuth/MSAL authentication). The explicit DO NOT USE FOR clause with redirects to azure-rbac and azure-keyvault-expiration-audit actively prevents conflicts with related Azure skills. | 3 / 3 |

Implementation
42%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The skill is well-structured as a navigation hub with excellent progressive disclosure to reference files, but the main body is too verbose—spending significant tokens on concept definitions and tables that Claude already understands. Actionability suffers because the SKILL.md itself delegates nearly all concrete, executable content to reference files without providing any inline code examples, and the workflow lacks validation checkpoints.
Suggestions
Remove or drastically condense the Key Concepts table, Application Types table, and Security Best Practices table—Claude already knows these concepts. Replace with only project-specific or non-obvious guidance.
Add at least one inline executable code example (e.g., a minimal Azure CLI app registration command with all required flags) so the skill is immediately actionable without needing to open reference files.
Add validation checkpoints to the workflow, such as 'Verify registration: `az ad app show --id <app-id>`' after Step 1, and a check after adding permissions to confirm they were granted.
Trim explanatory prose like 'Microsoft Entra ID (formerly Azure Active Directory) is Microsoft's cloud-based identity and access management service'—Claude knows this.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is verbose and explains many concepts Claude already knows (what an App Registration is, what a Tenant ID is, what MSAL is, application types table). The Key Concepts table, Application Types table, and much of the explanatory text add little value for Claude. The security best practices section lists generic advice Claude would already know. | 1 / 3 |
Actionability | The skill provides structured steps and references to external files for concrete commands and code, but the SKILL.md itself contains almost no executable code or copy-paste-ready commands. The portal method is described in vague UI navigation terms, and actual CLI commands are listed in a table but without full executable examples (arguments, flags, etc.). | 2 / 3 |
Workflow Clarity | The 5-step workflow is clearly sequenced and covers the main process, but there are no validation checkpoints or feedback loops. For operations involving secret creation (shown once, must copy immediately) and permission configuration, there's no verification step to confirm success or catch errors. | 2 / 3 |
Progressive Disclosure | The skill effectively uses a hub-and-spoke model with clear one-level-deep references to detailed files (CLI commands, OAuth flows, console app examples, API permissions, SDK references by language). References are well-signaled with descriptive labels and organized into logical sections. | 3 / 3 |
