Use this skill when you need to:

• Set up linting and formatting in a JavaScript, TypeScript, CSS, or JSON project using Biome
• Configure biome.json / biome.jsonc for a project
• Migrate from ESLint, Prettier, or other linters/formatters to Biome
• Run linting and formatting consistently in CI and local development
