The content is lean and efficient. The brief intro establishes Vite 8/Rolldown context without explaining what a build tool is. Tables are compact, code examples are minimal but complete, and no unnecessary explanations are included.

Provides executable CLI commands, a complete copy-paste-ready vite.config.ts example, specific plugin package names, and clear preferences (TypeScript, ESM). The common config example covers the most frequent use cases concretely.

For a configuration/reference skill like this, there isn't a multi-step destructive workflow requiring validation checkpoints. The CLI commands are clearly listed in logical order (dev → build → preview → SSR build), and the config example is unambiguous. This is appropriate for the skill's nature.

Excellent structure with a concise overview and well-organized tables pointing to one-level-deep reference files. Topics are logically grouped (Core, Build & SSR, Advanced), references are clearly signaled with descriptive links, and cross-skill references provide additional navigation.

Lists multiple specific concrete actions/domains: 'build tool configuration', 'plugin API', 'SSR', and 'Vite 8 Rolldown migration'. These are distinct, concrete capabilities rather than vague abstractions.

Clearly answers both 'what' (Vite build tool configuration, plugin API, SSR, Rolldown migration) and 'when' with an explicit 'Use when...' clause listing specific trigger scenarios (working with Vite projects, vite.config.ts, Vite plugins, building libraries/SSR apps).

Includes strong natural keywords users would say: 'Vite', 'vite.config.ts', 'Vite plugins', 'SSR', 'building libraries', 'Rolldown', 'Vite projects'. These cover common variations of how users would reference Vite-related work.

Highly distinctive with clear niche around Vite specifically. The mention of 'vite.config.ts', 'Vite plugins', 'Rolldown migration' makes it very unlikely to conflict with generic build tool or bundler skills (e.g., webpack, esbuild).
