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 clearly defines its scope around Microsoft Entra ID authentication and MSAL integration. It uses proper third-person voice, includes comprehensive trigger terms covering both legacy (Azure AD) and current (Entra ID) terminology, and the DO NOT USE FOR clause with explicit skill redirects is a best practice for preventing conflicts in a multi-skill environment.
| 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 a DO NOT USE FOR clause that further clarifies boundaries and redirects to other skills. | 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 specific alternative skills (azure-rbac, 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-organized with excellent progressive disclosure and clear navigation to reference materials, but suffers from significant verbosity by explaining concepts Claude already knows (identity platform basics, what app registrations are, application types). The main file lacks any executable code examples, deferring everything to reference files, which weakens actionability. Adding validation checkpoints and trimming explanatory content would significantly improve quality.
Suggestions
Remove the Key Concepts table, Application Types table, and overview paragraph — Claude already knows what Entra ID, Client IDs, Tenant IDs, and service principals are. Replace with only project-specific or non-obvious information.
Add at least one inline executable code example (e.g., a complete `az ad app create` command with typical arguments, or a minimal MSAL authentication snippet) rather than deferring all code to reference files.
Add validation checkpoints to the workflow, such as 'Verify registration: `az ad app show --id <app-id>` and confirm redirect URIs and permissions are correct' after Step 3, and a verification step after granting admin consent.
Condense the Security Best Practices table to only non-obvious recommendations — items like 'Use HTTPS only' and 'Never hardcode secrets' are well-known to Claude.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is verbose and explains many concepts Claude already knows (what an App Registration is, what a Client ID is, what a Tenant ID is, application types table, what MSAL is). 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. There are no inline code examples, no executable snippets, and the portal steps are high-level. The CLI commands table lists commands but doesn't show complete usage with arguments. | 2 / 3 |
Workflow Clarity | The 5-step workflow is clearly sequenced and logically ordered, 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 the registration is correct or that permissions were granted successfully. | 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, SDK references by language). Navigation is easy and references are clearly labeled with their purpose. | 3 / 3 |
