Quality
Discovery
89%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 a solid description with clear trigger guidance and a well-defined niche. It excels at distinctiveness and completeness with an explicit 'Use when' clause. The main weakness is that it could list more concrete actions (e.g., configure login/logout, token management, protect API calls) rather than just naming the integration mechanisms.
Suggestions
Expand the capability list with more concrete actions like 'configure login/logout flows, attach bearer tokens to API requests, protect routes with auth guards' to improve specificity.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (authentication in Angular) and some actions (route guards, HTTP interceptors), but doesn't list multiple concrete actions like 'configure login flows, protect routes, attach tokens to API calls'. The mention of SDK integration adds some specificity. | 2 / 3 |
Completeness | Explicitly answers both what (adding authentication with route guards and HTTP interceptors, integrating Auth0 SDK) and when ('Use when adding authentication to Angular applications'). The 'Use when...' clause is present and clear. | 3 / 3 |
Trigger Term Quality | Includes strong natural trigger terms: 'authentication', 'Angular', 'route guards', 'HTTP interceptors', '@auth0/auth0-angular', 'SPAs'. These are terms a user would naturally use when seeking this functionality. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive - targets a very specific niche: Auth0 authentication in Angular SPAs with specific mechanisms (route guards, HTTP interceptors). Unlikely to conflict with generic auth skills or other framework-specific skills. | 3 / 3 |

Implementation
72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-structured Auth0 Angular integration skill with strong actionability through complete, executable code examples and excellent progressive disclosure. Its main weaknesses are moderate verbosity (some sections like 'When NOT to Use' and 'Related Skills' could be trimmed) and missing validation checkpoints in the workflow, particularly around verifying the Auth0 dashboard configuration matches the app settings.
Suggestions
Add a validation checkpoint after Step 5, e.g., 'Verify: check browser console for errors; if you see redirect_uri mismatch, confirm Allowed Callback URLs in Auth0 Dashboard includes http://localhost:4200'
Remove or significantly trim the 'When NOT to Use' and 'Related Skills' sections to save tokens—Claude can infer these from context
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient with concrete code examples, but includes some unnecessary sections like 'When NOT to Use' with explanations Claude would already know, the 'Prerequisites' section is somewhat obvious, and the 'Related Skills' section adds little value. The Quick Reference section at the end partially duplicates what's already shown in the code examples. | 2 / 3 |
Actionability | Provides fully executable, copy-paste ready code for every step: npm install command, environment configuration, both standalone and NgModule setup patterns, and a complete component with login/logout UI. The common mistakes table also gives concrete fixes. | 3 / 3 |
Workflow Clarity | The 5-step workflow is clearly sequenced (install → configure env → configure module → add UI → test), but lacks validation checkpoints. Step 5 just says 'ng serve' with no guidance on what to verify, no mention of checking browser console for errors, and no feedback loop if Auth0 configuration is wrong (e.g., redirect URI mismatch). | 2 / 3 |
Progressive Disclosure | Excellent structure with a concise quick-start workflow in the main file and clearly signaled one-level-deep references to setup.md, integration.md, and api.md for detailed topics like guards, interceptors, and testing. The 'Detailed Documentation' section is well-organized with descriptive labels. | 3 / 3 |
