Discovery
75%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
The description is functional and covers both what and when adequately, with a clear Angular DI niche that reduces conflict risk. However, it could be stronger in specificity by listing more concrete actions and in trigger term quality by including more natural variations of terms users might use when seeking help with Angular dependency injection.
Suggestions
Add more specific concrete actions like 'create injection tokens, configure hierarchical injectors, set up useFactory/useClass/useValue providers, manage providedIn scoping'.
Expand trigger terms to include common variations like 'injection token', 'providedIn', 'useFactory', 'useClass', 'Angular services', 'service injection', '@Injectable'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Angular DI) and some actions ('Configure DI', 'inject() usage', 'defining providers'), but these are somewhat general categories rather than multiple specific concrete actions like 'create injection tokens, configure hierarchical injectors, use providedIn strategies'. | 2 / 3 |
Completeness | Clearly answers both 'what' (configure DI, inject() usage, providers in Angular) and 'when' with an explicit 'Use when...' clause specifying trigger conditions (configuring dependency injection, using inject(), defining providers). | 3 / 3 |
Trigger Term Quality | Includes relevant keywords like 'DI', 'inject()', 'providers', and 'Angular dependency injection', but misses common variations users might say such as 'injection token', 'providedIn', 'useFactory', 'useClass', 'service injection', or 'Angular services'. | 2 / 3 |
Distinctiveness Conflict Risk | The description targets a clear niche — Angular dependency injection specifically — which is distinct enough from general Angular skills or other framework skills. The mention of inject() and providers makes it unlikely to conflict with other skills. | 3 / 3 |

Implementation
85%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, concise Angular DI skill that efficiently communicates modern Angular patterns (inject(), providedIn, InjectionToken, provideAppInitializer). Its main weakness is the lack of complete, executable code examples — the inline code fragments are helpful but not copy-paste ready. The organization into Principles, Guidelines, and Anti-Patterns with a reference link is effective progressive disclosure.
Suggestions
Add at least one complete, executable code example showing a full provider configuration in app.config.ts with InjectionToken definition and inject() usage together.
Consider adding a brief executable example for the provideAppInitializer pattern since it's Angular 19+ specific and the syntax may be unfamiliar.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient, covering only Angular-specific DI patterns that Claude wouldn't inherently know (like Angular 19+ provideAppInitializer, multi providers syntax, route-scoped providers). No unnecessary explanations of what DI is or how it works generally. | 3 / 3 |
Actionability | Provides specific patterns and syntax snippets inline (e.g., inject(MyService), InjectionToken usage, provideAppInitializer), but lacks complete, executable code examples. The guidance is concrete but presented as inline code fragments rather than copy-paste ready blocks showing full context. | 2 / 3 |
Workflow Clarity | This is a single-purpose reference skill for DI configuration patterns, not a multi-step workflow. The content is clearly organized into Principles, Guidelines, and Anti-Patterns sections, making it unambiguous which pattern to apply in which situation. | 3 / 3 |
Progressive Disclosure | The skill provides a concise overview with well-organized sections and a clear one-level-deep reference to 'references/di-patterns.md' for detailed patterns. Content is appropriately split between the overview and the referenced file. | 3 / 3 |
