angular-dependency-injection
Configure DI, inject() usage, and providers in Angular. Use when configuring Angular dependency injection, using inject(), or defining providers. (triggers: **/*.service.ts, angular inject, providedIn, injection token, provideAppInitializer)

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 skill description that clearly identifies its niche (Angular dependency injection) with explicit 'Use when' guidance and well-chosen trigger terms. The main weakness is that the capability listing could be more specific with concrete actions beyond the general 'configure DI, inject() usage, and providers'. Overall it performs well for skill selection purposes.
Suggestions
Expand the capability list with more concrete actions, e.g., 'Create custom injection tokens, configure hierarchical injectors, set up factory and value providers, migrate to standalone inject() function'.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Angular DI) and some actions ('Configure DI, inject() usage, and providers'), but the actions are somewhat general and not deeply specific—e.g., it doesn't list concrete tasks like 'create custom injection tokens, configure hierarchical injectors, set up factory providers'. | 2 / 3 |
Completeness | Clearly answers both 'what' (configure DI, inject() usage, providers in Angular) and 'when' (explicit 'Use when...' clause with trigger terms and file patterns), meeting the criteria for a score of 3. | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'inject()', 'providedIn', 'injection token', 'provideAppInitializer', '*.service.ts', and 'Angular dependency injection'. These cover common variations and file patterns well. | 3 / 3 |
Distinctiveness Conflict Risk | Highly specific to Angular dependency injection with distinct triggers like 'inject()', 'providedIn', 'injection token', and 'provideAppInitializer' that are unlikely to conflict with other skills. The file pattern '**/*.service.ts' further narrows the scope. | 3 / 3 |
Total | 11 / 12 Passed |
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-crafted, concise Angular DI skill that efficiently communicates modern patterns (Angular 19+), clear preferences (inject() over constructor, providedIn: 'root'), and anti-patterns. Its main weakness is the lack of complete, executable code examples — the inline snippets are helpful but a short complete example showing a service with inject() and an app.config.ts setup would significantly improve actionability.
Suggestions
Add a short, complete executable example showing a service using inject() and its registration in app.config.ts to improve actionability from reference-style notes to copy-paste ready guidance.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Every line delivers Angular DI-specific knowledge that Claude wouldn't inherently know (Angular 19+ patterns, specific API choices, anti-patterns). No unnecessary explanations of what DI is or how Angular works generally. Bold formatting highlights key terms efficiently. | 3 / 3 |
Actionability | Provides specific API names, patterns, and inline code snippets (e.g., inject(MyService), InjectionToken usage, provideAppInitializer syntax), but lacks complete executable code examples. The guidance is concrete but closer to reference notes than copy-paste ready code blocks. | 2 / 3 |
Workflow Clarity | This is a reference/pattern skill rather than a multi-step workflow skill. The single-purpose guidance is unambiguous — it clearly states when to use each pattern (e.g., inject() over constructor, providedIn: 'root' for singletons, route providers for scoped services). No destructive or batch operations require validation checkpoints. | 3 / 3 |
Progressive Disclosure | The skill is well-structured with clear sections (Principles, Guidelines, Anti-Patterns) and appropriately references a single deeper document [DI Patterns](references/di-patterns.md) for extended content. One level deep, clearly signaled. | 3 / 3 |
Total | 11 / 12 Passed |
