Use this skill when implementing or modifying Biome's formatters. It covers the trait-based formatting system, IR generation, comment handling, and testing with Prettier comparison.
This generates FormatNodeRule implementations for all syntax nodes. Initial implementations use formatverbatimnode (formats code as-is).
Leading and trailing comments are handled automatically by the formatter infrastructure.
