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 well-crafted skill description that excels at trigger terms and distinctiveness by combining Angular-specific terminology with Auth0 SDK references. The explicit 'Use when...' clause ensures completeness. The main weakness is that it describes integration at a high level rather than listing specific concrete actions the skill enables.
Suggestions
Add specific concrete actions like 'configure login/logout flows, protect routes with AuthGuard, attach tokens to API requests, handle authentication state'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Angular authentication) and mentions specific components (route guards, HTTP interceptors, @auth0/auth0-angular SDK), but doesn't list multiple concrete actions - it describes integration rather than specific capabilities like 'configure login flows, protect routes, handle token refresh'. | 2 / 3 |
Completeness | Explicitly answers both what (adding authentication with route guards and HTTP interceptors, integrating Auth0 SDK) and when (starts with 'Use when adding authentication to Angular applications'). The 'Use when...' clause is present and clear. | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'authentication', 'Angular', 'route guards', 'HTTP interceptors', 'auth0', 'SDK', 'SPAs'. Good coverage of both general terms (authentication) and specific technical terms users familiar with Angular would use. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear niche: specifically Angular + Auth0 + SPAs. The combination of framework (Angular), library (@auth0/auth0-angular), and specific patterns (route guards, HTTP interceptors) makes it unlikely to conflict with generic auth skills or other framework auth skills. | 3 / 3 |
Total | 11 / 12 Passed |
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 skill with excellent actionability - all code examples are complete and executable. The progressive disclosure is exemplary with clear navigation to reference materials. Main weaknesses are minor verbosity in explanatory sections and missing explicit validation steps in the workflow (e.g., how to verify authentication is working correctly).
Suggestions
Add explicit validation step after 'ng serve' - e.g., 'Verify: Click Login, complete Auth0 flow, confirm user profile displays'
Trim the 'When NOT to Use' section to a single line or move to reference docs - Claude can infer these constraints
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is mostly efficient with good code examples, but includes some unnecessary sections like 'When NOT to Use' explanations and verbose table entries that Claude could infer. The Prerequisites section explaining what Auth0 is could be trimmed. | 2 / 3 |
Actionability | Provides fully executable, copy-paste ready code for all steps including npm install, environment config, module setup for both standalone and NgModule patterns, and complete component code with template. Commands are specific and complete. | 3 / 3 |
Workflow Clarity | Steps are clearly numbered 1-5 with logical sequence, but lacks explicit validation checkpoints. Step 5 says 'Test Authentication' but doesn't specify what to verify or how to confirm success. No error recovery guidance in the main workflow. | 2 / 3 |
Progressive Disclosure | Excellent structure with Quick Start in main file and clear one-level-deep references to Setup Guide, Integration Guide, and API Reference. The 'Detailed Documentation' section clearly signals where to find advanced topics with descriptive labels. | 3 / 3 |
Total | 10 / 12 Passed |
