Discovery
100%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 strong skill description that clearly identifies the domain (Vite), lists specific capabilities (configuration, plugin API, SSR, Rolldown migration), and provides explicit trigger guidance with natural keywords. It uses proper third-person voice and is concise without being vague. The description would effectively differentiate this skill from other build tool or frontend skills.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | 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 language. | 3 / 3 |
Completeness | 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 like working with Vite projects, vite.config.ts, plugins, or building libraries/SSR apps. | 3 / 3 |
Trigger Term Quality | Includes strong natural keywords users would say: 'Vite projects', 'vite.config.ts', 'Vite plugins', 'SSR', 'building libraries', 'Rolldown migration'. Covers both the tool name and specific file/concept terms users would mention. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with clear niche around Vite specifically. Terms like 'vite.config.ts', 'Vite plugins', 'Rolldown migration' are unique to Vite and unlikely to conflict with other build tool skills (e.g., webpack, esbuild). | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
100%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-crafted skill that serves as an efficient index into Vite's ecosystem. It provides just enough inline content (CLI commands, common config, plugin list) to be immediately useful while properly delegating detailed topics to reference files. The content is concise, actionable, and well-organized with clear progressive disclosure.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is lean and efficient. The brief intro is justified (Vite 8/Rolldown context is new information). Tables are compact, code examples are minimal but complete, and there's no explanation of concepts Claude already knows. | 3 / 3 |
Actionability | Provides executable CLI commands, a complete copy-paste-ready vite.config.ts example, specific plugin package names, and clear preferences (TypeScript, ESM). The quick reference section gives concrete, immediately usable guidance. | 3 / 3 |
Workflow Clarity | For a configuration/reference skill like this, there isn't a destructive multi-step workflow requiring validation checkpoints. The CLI commands are clearly listed, the config example is unambiguous, and the table-based organization makes topic discovery straightforward. This is appropriate for the skill's nature. | 3 / 3 |
Progressive Disclosure | Excellent structure with a concise overview and well-signaled one-level-deep references to detailed files (core-config.md, core-features.md, core-plugin-api.md, build-and-ssr.md, environment-api.md, rolldown-migration.md). Topics are logically grouped into Core, Build & SSR, and Advanced sections. Cross-skill references are also well-handled. | 3 / 3 |
Total | 12 / 12 Passed |
