This validates your Biome configuration against 2.3+ standards and catches outdated patterns before they bite you. Run it when setting up linting, after AI generates a biome.json, or when auditing existing projects. It checks schema versions, ensures you're using the new assist.actions syntax instead of the deprecated organizeImports config, verifies package versions are current, and flags missing domains for React or Next.js projects. The honest take: Biome moved fast between 1.x and 2.x, and this prevents you from shipping configs that look fine but use patterns that stopped working three versions ago. Includes a recommended baseline config and ESLint migration steps if you're making the switch.
