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), Azure resource security (use azure-security).

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 key dimensions well. It provides specific capabilities, comprehensive trigger terms covering both legacy and current Azure naming, explicit 'use when' guidance, and notably includes 'do not use for' clauses that reduce conflict risk with related Azure skills. The description is concise yet thorough.
| 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 setup. | 3 / 3 |
Completeness | Clearly answers 'what' (guides app registration, OAuth, MSAL integration) and 'when' with explicit USE FOR triggers. Additionally includes DO NOT USE FOR clauses with alternative skill recommendations, which 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 explicit boundary-setting via DO NOT USE FOR clauses that redirect to specific alternative skills (azure-rbac, azure-keyvault-expiration-audit, azure-security). The niche of Entra ID/OAuth/MSAL is clearly carved out from adjacent 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 has excellent structure and progressive disclosure, appropriately delegating detailed content to reference files. However, it is overly verbose in the main body, spending significant tokens explaining concepts Claude already understands (identity concepts, application types, what MSAL is). The actionability suffers because nearly all concrete, executable guidance is deferred to references, leaving the main skill body as mostly descriptive rather than instructive.
Suggestions
Remove the Key Concepts and Application Types tables - Claude already knows these. Replace with a brief note like 'Gather: app name, type (web/SPA/mobile/daemon), redirect URIs, required permissions' to jump straight into the workflow.
Include at least one complete, executable CLI command inline (e.g., `az ad app create --display-name 'MyApp' --sign-in-audience AzureADMyOrg`) rather than deferring all concrete commands to reference files.
Add validation checkpoints to the workflow, e.g., after Step 1: 'Verify: `az ad app show --id <app-id>` returns the expected configuration' and after Step 3: 'Verify permissions: `az ad app permission list --id <app-id>`'.
Trim the Security Best Practices table to only non-obvious recommendations (e.g., remove 'Use HTTPS only' and 'Enable MFA' which are standard knowledge) to reduce token usage.
| 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). The Key Concepts table, Application Types table, and much of the descriptive text add little value for Claude. The overview paragraph explaining what Entra ID is wastes tokens. | 1 / 3 |
Actionability | The skill provides some concrete guidance (CLI command names, portal navigation steps, permission names) but almost all executable content is deferred to reference files. The main body contains no executable code examples, no copy-paste ready commands, and relies heavily on 'See [reference]' links for actual implementation details. | 2 / 3 |
Workflow Clarity | The 5-step workflow is clearly sequenced and logically ordered, but lacks validation checkpoints. There's no verification step after registration, no way to confirm permissions were granted correctly, and no error recovery guidance. For a multi-step process involving security-sensitive configuration, the absence of validation steps is notable. | 2 / 3 |
Progressive Disclosure | The skill excels at progressive disclosure with a clear overview structure and well-signaled one-level-deep references to detailed files (CLI commands, OAuth flows, console app examples, API permissions, troubleshooting). References are clearly labeled with purpose descriptions and organized logically. | 3 / 3 |
Total | 8 / 12 Passed |
