Biome Developer

If you're contributing to the Biome codebase, this skill is a solid reference for avoiding the paper cuts that trip up new contributors. It covers AST inspection shortcuts (use the parser's quick_test instead of building the whole binary), string extraction gotchas (inner_string_text versus text_trimmed), and framework-specific quirks like Vue using quoted strings while Svelte uses curly braces. The borrow checker guidance and clippy patterns are immediately useful. Most valuable for understanding how Biome handles embedded languages across different frameworks. The tone is practical and assumes you're already writing Rust, not learning it.
