formatter-development

The skill is a coherent developer tooling guide for Biome formatters. It describes legitimate workflows (boilerplate generation, node formatting, IR usage, comment handling, Prettier comparison, and tests) and relies on user-managed tool installations. There are no suspicious data flows, credential handling, or external data exfiltration patterns evident in the described content. Overall, the footprint is benign and proportionate to its stated purpose as a formatter development guide.
