Quick Start
Install:
npx skills add biomejs/biome --skill biome-developer -y -g -a antigravity claude-code codex crush cursor gemini-cli github-copilot grok opencodeUse: /biome-developer
Works with Claude Code, Gemini CLI, OpenCode, and other agentskills.io-compatible agents.
What It Does
Section titled “What It Does”biome-developer supplies internal best practices and gotchas for contributors working on the Biome (formatter/linter) codebase itself. It covers AST navigation, string extraction without allocation, embedded language handling, clippy/style rules (no emojis, let chains, path imports), dev-dependency path usage, comment guidelines, testing via quick_test, and common API confusion tables. Marked as compatibility: “Designed for coding agents working on the Biome codebase (github.com/biomejs/biome).”
Harness Coverage
Section titled “Harness Coverage”Targets verified harnesses: antigravity, claude-code, codex, crush, cursor, gemini-cli, github-copilot, grok, opencode.
Portable multi-harness install command:
