Lean and dense; no preamble explaining what Angular/RxJS is, every bullet states a concrete rule and API. It does not explain concepts Claude already knows, and each token earns its place.

Provides concrete snippets like 'http.get<User[]>(...).pipe(catchError(() => of([])))' and named APIs, but several examples are partial/inline rather than complete executable code (e.g. toSignal/toObservable calls lack full import + injection context wiring), so it falls short of copy-paste ready.

Principles and anti-patterns are well organized but there is no explicit sequenced workflow with validation checkpoints; the HTTP and race-condition guidance lists steps implicitly without a validate/retry feedback loop, matching the score-2 anchor.

A concise overview body with a single one-level-deep reference to references/observables-vs-signals.md, which exists and is well-organized; navigation is clearly signaled and appropriately split.

Names concrete actions ('Bridge Observables and Signals using toSignal and toObservable') plus specific APIs, listing multiple specific concrete actions like the score-3 anchor.

Clearly states what it does ('Bridge Observables and Signals...') and when to use it ('Use when converting between RxJS Observables and Angular Signals'), answering both what and when with an explicit trigger clause.

Includes natural terms users would say ('Observables', 'Signals', 'RxJS Observables', 'Angular Signals', 'toSignal', 'toObservable') with good coverage of common variations.

Targets a clear niche (RxJS/Angular interop) with distinct triggers unlikely to conflict with other skills; the combination of toSignal/toObservable is specific to this domain.
