Conciseness

The body is lean bullet-point guidance that assumes Claude's competence — "Run `ng add @angular/ssr`", "Defer hydration with `@defer (hydrate on viewport)`" — with no explanation of what SSR or hydration are. Every section earns its place; the only marginal redundancy is the hydration.md link appearing in both section 1 and the References section, which is not enough to drop below the 'lean and efficient' anchor.

Actionability

Most guidance is concrete and executable: `ng add @angular/ssr`, `provideClientHydration(withEventReplay())`, named `@defer` triggers, and named RenderMode enum values with route-appropriate use cases. It falls short of fully copy-paste ready because section 4 says "Export `ServerRoute[]` in `app.routes.server.ts`" without showing a route-config example, and `TransferState` is only named, not demonstrated — matching 'concrete code or commands with minor gaps' rather than the 5 anchor.

Workflow Clarity

Sections 1–5 form a sensible ordered sequence (enable hydration → guard browser-only code → prevent double-fetching → configure render modes → incremental hydration), and the Anti-Patterns section reinforces the guardrails. This is configuration guidance, not a destructive or batch operation, so no validation loop is required; it sits at 'clear sequence with minor gaps' because steps are independent config tasks rather than a strictly dependent sequence, keeping it below the explicit-checkpoint anchor.

Progressive Disclosure

The bundle structure is appropriate: a concise overview body plus one real, one-level-deep reference (`references/hydration.md`, 41 lines of complete code examples), linked with a descriptive label ("See [hydration examples](references/hydration.md) for app config and hydration setup"). Two issues keep it from the top anchor: the reference is linked twice (section 1 and the References section), and the reference contradicts the body — the body says to use `isPlatformBrowser(platformId)` while hydration.md says "Do not use `isPlatformBrowser`. Use Lifecycle hooks." — an organization/consistency gap.

Specificity

The description lists multiple concrete capabilities — "Implement Angular SSR with hydration, TransferState caching, and per-route render modes" — naming specific APIs and features rather than generic actions. This matches the 'comprehensive coverage' anchor; it is not a 4 because no meaningful capability of the skill's stated scope is left unnamed.

Completeness

It explicitly answers both questions: what it does ("Implement Angular SSR with hydration, TransferState caching, and per-route render modes") and when to use it ("Use when configuring Angular Universal SSR, client hydration, static prerendering, or preventing double-fetching") with concrete trigger phrases. This is a direct match for the top anchor; a 'Use when...' clause is present and specific.

Trigger Term Quality

"Use when configuring Angular Universal SSR, client hydration, static prerendering, or preventing double-fetching" covers the key natural phrases a user would say. It misses a few common variations — "server-side rendering" spelled out, "SEO", or version-specific phrasing like "Angular 17" — so it falls just below the comprehensive-synonyms anchor (5) but clearly above 'a few natural terms missing' being only partially satisfied.

Distinctiveness Conflict Risk

"Angular SSR" with triggers like "Angular Universal SSR", "client hydration", and "prerendering" carves out a clear niche that would not fire for general Angular component work or non-Angular SSR frameworks. Minimal conflict risk; the 4 anchor ('minor overlap risk with closely related skills') is a weaker fit because the triggers are all SSR/hydration-specific.
