What problem does it solve?

Biome configurations often drift from the expected schema and recommended settings, causing CI failures and stale setups. This Skill provides automated checks to ensure Biome 2.3+ compatibility, proper schema usage, and up-to-date configuration patterns.

Core Features & Use Cases

• Configuration validation: ensures correct $schema, Biome version, and core sections (linter, assist, and formatter).
• CI readiness: detects deprecated keys, missing domains, and outdated patterns, with fixes to pass validation in pipelines.
• Audits existing projects: quickly validates current Biome setups and suggests improvements.

Quick Start

Run the validator from your project root to verify Biome configuration:

• python3 path/to/validate.py --root .
• python3 path/to/validate.py --root . --strict
