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, focused skill description that clearly identifies its niche at the intersection of RxJS Observables and Angular Signals. It includes an explicit 'Use when' clause and good trigger terms. The main weakness is that the 'what' portion could be more specific about the concrete actions or scenarios beyond just 'bridging' and 'converting'.
Suggestions
Expand the capabilities list with more concrete actions, e.g., 'Convert Observable streams to reactive Signals with toSignal, convert Signals back to Observables with toObservable, handle initial values, manage subscription cleanup.'
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Names the domain (Angular Signals/RxJS Observables) and the specific functions (toSignal, toObservable), but doesn't list multiple concrete actions beyond 'bridge' and 'converting'. Could elaborate on specific use cases like handling initial values, error handling, or subscription management. | 2 / 3 |
Completeness | Clearly answers both 'what' (bridge Observables and Signals using toSignal and toObservable in Angular) and 'when' (Use when converting between RxJS Observables and Angular Signals) with an explicit 'Use when' clause. | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would actually say: 'Observables', 'Signals', 'toSignal', 'toObservable', 'RxJS', 'Angular', and 'converting'. These cover the main terms a developer would use when seeking this functionality. | 3 / 3 |
Distinctiveness Conflict Risk | Very specific niche targeting the interop between RxJS Observables and Angular Signals with named utility functions. Unlikely to conflict with general Angular skills or general RxJS skills due to the precise scope. | 3 / 3 |

Implementation
57%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill covers the key Angular RxJS interop APIs concisely and identifies important anti-patterns, which is valuable. However, it lacks complete executable code examples — a full component snippet showing toSignal/toObservable in context would significantly improve actionability. Minor redundancy (auto-unsubscribe mentioned twice) and the absence of a clear step-by-step workflow for the common Signal↔Observable conversion pipeline slightly weaken the content.
Suggestions
Add a complete, executable component example showing toSignal() converting an HTTP Observable to a Signal used in a template, and another showing the toObservable → RxJS operators → toSignal pipeline.
Remove the redundant 'Auto-Unsubscribe' bullet since it's already covered in the first principle, to improve conciseness.
Add a numbered step-by-step workflow for the common pattern: create Signal → toObservable → apply debounceTime/switchMap → toSignal → render in template, with validation notes about injection context requirements.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient but has some redundancy — 'Auto-Unsubscribe' is stated as a separate principle but was already mentioned in the first bullet. Some bold formatting is excessive and adds visual noise without adding information. | 2 / 3 |
Actionability | Provides inline code snippets and specific API calls (toSignal, toObservable, takeUntilDestroyed) but lacks complete, executable code examples. The HTTP example is a fragment rather than a copy-paste-ready block showing a full component usage pattern. | 2 / 3 |
Workflow Clarity | The Observable-to-Signal and Signal-to-Observable patterns are described but not sequenced as clear step-by-step workflows. The 'Sync to Async' flow (Signal → toObservable → RxJS operators → toSignal) is mentioned but would benefit from an explicit numbered sequence or a complete code example showing the full pipeline. | 2 / 3 |
Progressive Disclosure | For a skill of this size, the content is well-organized into clear sections (Principles, Guidelines, Anti-Patterns, References) with a single-level reference to a separate file for deeper comparison of Signals vs Observables. | 3 / 3 |
