Tools

vite_docs_search

Semantic search over Vite documentation. Uses a 6-step pipeline: embed query, hybrid search (dense + BM25), resolve HyPE hits, expand cross-references, rerank, and reconstruct into readable markdown.

query	string		Developer question or topic (max 2000 chars)
scope	string	"all"	Documentation section to search within
max_results	integer	3	Number of sections to return (1-20)

Scope values: all, guide, config, changes, plugins

vite_api_lookup

Fast exact-match API reference lookup with fuzzy fallback. Returns type signatures, descriptions, and usage examples directly from the documentation.

Parameter	Type	Default	Description
name	string		API name to look up (e.g. defineConfig, createServer, server.proxy)

vite_get_related

Find related APIs, concepts, and documentation pages for a given API or topic.

Parameter	Type	Default	Description
name	string		API name or concept to explore

Resources

URI	Description
vite://topics	Full table of contents
vite://topics/{section}	TOC for a specific section (e.g. vite://topics/guide)
vite://pages/{path}	Raw markdown of any doc page (e.g. vite://pages/config/shared-options)
vite://api/index	Complete API entity index grouped by type
vite://api/entities/{name}	Details for a specific API (e.g. vite://api/entities/defineConfig)
vite://scopes	All valid search scope values

Prompts

Benchmarks vs Context7

Evaluated on 49 Vite questions scored by an LLM judge (Gemini, temperature 0) across 5 dimensions on a 1-5 scale.

Methodology

Each question has a ground-truth answer with expected API names and documentation paths. Both providers receive the same question and return documentation context. The judge scores the retrieved context on relevance, completeness, correctness, API coverage, and conciseness. See the eval/ directory in the repository for the full evaluation framework.
