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 app registration and OAuth authentication. It uses comprehensive trigger terms covering both legacy (Azure AD) and current (Entra ID) terminology, and the explicit DO NOT USE FOR clause with skill redirects is a best practice for reducing conflict risk. The description is concise yet thorough, using proper third-person voice throughout.
| 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 app registration, OAuth, 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 explicit boundary-setting via the DO NOT USE FOR clause, which names specific competing skills (azure-rbac, azure-keyvault-expiration-audit). The domain is narrowly scoped to identity/authentication concerns, making conflicts unlikely. | 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, with well-organized references to detailed materials. However, it spends too many tokens explaining concepts Claude already knows (identity concepts, application types, generic security practices) and delegates nearly all executable content to reference files, leaving the main body with little actionable, copy-paste-ready guidance. Adding at least one concrete CLI example and removing definitional tables would significantly improve it.
Suggestions
Remove or drastically condense the 'Key Concepts' and 'Application Types' tables — Claude already knows what a Client ID, Tenant ID, and redirect URI are. Replace with a brief note only if there's project-specific naming or configuration.
Add at least one complete, executable CLI example 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 core workflow, such as 'Verify registration: `az ad app show --id <app-id>` should return the app details' after Step 1, and 'Test authentication: attempt a token acquisition before proceeding' after Step 5.
Trim the Security Best Practices table to only non-obvious, project-specific recommendations — generic advice like 'Use HTTPS' and 'Enable MFA' wastes tokens on things Claude already knows.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The overview explains what Entra ID is and defines basic concepts (App Registration, Client ID, Tenant ID, etc.) that Claude already knows. The 'Key Concepts' and 'Application Types' tables are padding that don't add actionable value. The security best practices table contains generic advice Claude would already follow. Significant token budget is spent on descriptions rather than instructions. | 1 / 3 |
Actionability | The skill provides some concrete guidance (portal steps, CLI command table, common Graph permissions) but almost all executable content is deferred to reference files. The main body contains no executable code examples, no copy-paste ready commands, and the CLI table only lists commands without arguments or examples. The 'Common Patterns' section describes what information is needed but delegates all implementation. | 2 / 3 |
Workflow Clarity | The 5-step core workflow is clearly sequenced and logically ordered, which is good. However, there are no validation checkpoints — no step to verify the registration succeeded, no step to test that permissions are correctly configured, no feedback loop for common errors like consent not being granted. For a multi-step process involving security configuration, the absence of verification steps is a notable gap. | 2 / 3 |
Progressive Disclosure | The skill excels at progressive disclosure with a clear overview structure and well-signaled one-level-deep references to CLI commands, OAuth flows, console app examples, API permissions, troubleshooting, and SDK references. Navigation is easy with a dedicated References section and inline links throughout. Content is appropriately split between the overview and detailed reference files. | 3 / 3 |
