Examples:<example>User needs to create a diagnostic for a lint rule</example><example>User wants to add helpful advice to error messages</example><example>User is improving diagnostic quality</example>
General development best practices and common gotchas when working on Biome. Use for avoiding common mistakes, understanding Biome-specific patterns, and learning technical tips. Examples:<example>Working with Biome's AST and syntax nodes</example><example>Understanding string extraction methods</example><example>Handling embedded languages and directives</example>
Fast linting/formatting for TypeScript/React. Use when setting up linter, migrating from ESLint/Prettier, or running code quality checks.
Use when applying Biome's linting capabilities, rule categories, and code quality enforcement to JavaScript/TypeScript projects.
Biome 2.x linting and formatting patterns. Use when configuring code quality tools, setting up linting rules, formatting code, or integrating with CI/CD. Covers migration from ESLint/Prettier.
Guide for working with Biome's module graph and type inference system. Use when implementing type-aware lint rules or working on TypeScript support. Examples:<example>User needs to understand type resolution for a lint rule</example><example>User is working on the module graph infrastructure</example><example>User wants to implement type inference for a new feature</example>
