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 well-structured with a clear 'Use when' clause and good distinctiveness for Angular DI. However, the 'what' portion is somewhat terse and repetitive with the 'when' clause, and the trigger terms could be expanded to cover more natural user phrasings and specific DI concepts.
Suggestions
Expand specific actions beyond general categories, e.g., 'Create injection tokens, configure hierarchical injectors, set up providedIn strategies, use useFactory/useClass/useValue providers'.
Add more natural trigger terms users might say, such as 'injection token', 'InjectionToken', 'providedIn', 'service injection', 'useFactory', 'useClass', 'useValue', 'injector hierarchy'.
| 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, and providers in Angular) and 'when' with an explicit 'Use when...' clause specifying trigger conditions (configuring Angular dependency injection, using inject(), or 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', 'service injection', 'useFactory', 'useClass', 'InjectionToken', or 'hierarchical injectors'. | 2 / 3 |
Distinctiveness Conflict Risk | Clearly scoped to Angular dependency injection specifically, which is a distinct niche unlikely to conflict with other skills. The mention of Angular-specific concepts like 'inject()' and 'providers' makes it clearly distinguishable. | 3 / 3 |

Implementation
77%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, concise Angular DI skill that efficiently communicates modern patterns (inject(), providedIn: 'root', provideAppInitializer) and anti-patterns. Its main weakness is the lack of complete executable code examples — the inline code fragments are helpful but a short concrete example block would improve actionability. The referenced di-patterns.md file is not present in the bundle, making progressive disclosure harder to fully evaluate.
Suggestions
Add a short, complete executable code example showing a typical DI setup (e.g., an InjectionToken defined, provided in app.config.ts, and injected via inject()) to improve actionability.
Include the referenced 'references/di-patterns.md' file in the bundle, or remove the reference if it doesn't exist yet.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. It avoids explaining what DI is or how Angular works fundamentally, instead jumping straight to specific patterns and decisions. Every bullet point conveys actionable, non-obvious guidance. | 3 / 3 |
Actionability | Provides specific patterns and syntax (e.g., inject(), InjectionToken, provideAppInitializer) with inline code snippets, 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 configuration/pattern skill rather than a multi-step workflow skill. The single-task guidance is unambiguous — it clearly states when to use each pattern (e.g., route providers for scoped services, useFactory for runtime config, provideAppInitializer for pre-bootstrap). No destructive or batch operations require validation checkpoints. | 3 / 3 |
Progressive Disclosure | References a 'references/di-patterns.md' file for deeper patterns, which is good structure. However, the bundle has no files, so the reference is unverifiable. The single reference is appropriately signaled but the skill could benefit from clearer navigation to what additional content exists in that reference. | 2 / 3 |
