# @cssdoc/providers

`@cssdoc/providers` — the host-agnostic language-service core. It exposes diagnostics (author-side
hygiene and consumer-side usage), completions, hover, and definitions over a `@cssdoc/index`, built
from modular aspect modules. Every adapter — the Stylelint and ESLint plugins, and the language
server — is a thin translation of these into its host's API.
