The skill is remarkably efficient — it assumes Claude already knows Svelte syntax and focuses entirely on changing defaults and mental models. Every principle is stated as a concise rule with a brief rationale, code examples are minimal but illustrative, and there's no padding or explanation of basics.

The skill provides concrete, executable Svelte 5 code examples with clear ❌/✅ patterns, a structured review process (4 steps), and a comprehensive smell index that maps directly to referenced guides. The 'Running a Review' section gives specific, actionable steps including what to check first and how to prioritize output.

The 'Running a Review' section provides a clear 4-step sequence: detect version → apply principles with smell index → judge performance on evidence → shape output by priority. The workflow includes validation (check package.json first, don't recommend wrong-version syntax) and prioritization guidance (high-impact first, then rewrites, then nice-to-haves).

The skill is an exemplary overview that states each principle concisely inline, then points to one-level-deep reference files for details. Every reference is clearly signaled with descriptive names and consistent linking. The smell index serves as a navigation table mapping problems to specific reference files. Cross-references to the sveltekit skill are clearly noted. However, no bundle files were provided to verify the references exist.

Lists multiple specific concrete actions: reviews components for idiomatic patterns, identifies anti-patterns from React/Vue/Svelte 4, suggests Svelte 5 refactorings. Also enumerates many specific code smells like 'effect assigns state', 'prop copied to $state', 'createEventDispatcher', 'export let', etc.

Clearly answers both 'what' (reviews Svelte components, identifies anti-patterns, suggests refactorings) and 'when' (explicit 'Use when...' clause with multiple trigger scenarios). Also clarifies scope boundaries by noting delegation to sveltekit for routes/load/actions.

Excellent coverage of natural trigger terms users would say: 'is this idiomatic', 'Svelte way', 'Svelte 5 migration', plus specific technical terms like 'createEventDispatcher', 'export let', 'on:click', 'slot-shaped APIs', '$bindable', 'shadcn-svelte'. These are terms a developer would naturally use when seeking Svelte review help.

Highly distinctive with a clear niche in Svelte component review specifically. Explicitly delineates boundaries with related skills (delegates to sveltekit for routes/load/actions/server concerns), reducing conflict risk. The extensive list of Svelte-specific smells makes it very unlikely to trigger for non-Svelte tasks.
